Astronomers have witnessed the biggest bang since the big bang— moment about 15 billion years ago when the universe was created in a massive explosion. The huge burst of energy from the edge of the universe is estimated to be second only to the moment of creation in its explosive force, releasing more energy in two seconds than the sun will give out in it lifetime. Scientists hope the explosion—known as a gamma-ray burst because it emits energy in the form of gamma radiation—will shed light on the earliest stages in the evolution of the stars and galaxies. Gamma-ray bursts cannot be seen by the human eye, but if they could the sky would light up like a camera flash each time they occurred. They are by far the most energetic events in the universe and, until now, have remained largely a mystery.
The latest gamma-ray burst to be detected accurately occurred last December. Using a network of telescopes and satellites, the astronomers were able to calculate its distance from Earth at about 15 billion light years. This means it must have happened soon after the big bang itself, while the intensity of the radiation revealed it to be the biggest bang recorded by man. Scientists from the American National Aeronautics and Space Administration and the California Institute of Technology are to announce details of their analysis this week. The huge distance between the source of the explosion and the Earth suggests gamma-ray bursts are up to 10 times larger than previously thought, said Jonathan Katz, professor of physics at Washington University in St Louis.
“Gamma-ray bursts may be the most distant things we will ever see and as such will act as beacons to probe into the very distant regions of the universe when stars and galaxies were first formed.”
American spy satellites looking for the radiation released from Soviet nuclear tests first detected gamma-ray bursts in 1967 but the details were kept classified until 1973. For nearly 25 years scientists were hampered in their efforts to find an explanation for the huge explosions because they lasted no longer than a few seconds. The inability to explain them led to speculation that gamma-ray bursts were the remnants of nuclear battles between alien civilizations, or even the exhaust energy of extraterrestrial spaceships going into warp drive. Two satellites, the American Compton gamma-ray observatory and the Italian-Dutch Bepposax satellite, have now been able to locate the precise direction of gamma-ray bursts within seconds of them occurring. John Quenby, professor of physics at Imperial College of Science, Technology and Medicine in London, said the most likely explanation for gamma-ray burst is that they result from the enormous energy released when two very dense objects—called neutron stars—collide

Around the World in 20 Days

Bertrand: In many people’s eyes, a round-the-world balloon flight was the last great challenge in aviation. The winter of 1998-99 was time of high anxiety. Five other teams were preparing to launch in various parts of the world. This would be my third, and last, attempt underwritten by the Breitling watch company. The weather was terrible, and February was drawing to a close. Normally the end of the month marked the end of the season for ballooning attempts. I was in despair. But early on February 24, 1999, the telephone rang. It was Luc Trullemans, one of our meteorologists.
“, there’s a really good slot coming on the first of March!” he exclaimed. Trullemans and fellow meteorologist Pierre Eckert felt sure we could swing the balloon around the edge of a big depression forming over the Mediterranean by flying counterclockwise—going down over France and Spain. Then we would be carried eastward over Africa.
Brian Jones, my British co-pilot, and I knew if the weather turned, we would fail. But if we waited for next year, somebody else might succeed in the interim.
A balloon piloted by British tycoon Richard Branson hand gone down in the Pacific, but one sponsored by Britain’s Cable & Wireless and piloted by Andy Elson and Colin Prescot had already been aloft for seven days. On Sunday, February 28, we struggled to make the crucial decision: carry on or not? Brian and I knew this was our last chance for 1999. Alan Noble, our flight director, and Don Cameron, head of the firm that built the balloon, were far from being positive. “From the weather maps,” they said, “we don’t see how you can get around the world.”
“You get them up there,” argued Luc, “and I’ll get them around.”
Following meteorological assurances, Alan said, “I think we can go.” We put it to a vote of the whole team, and the show of hands to take off was unanimous. By five the next morning, Brian and I were both wide awake. After years of preparation and dashed hopes, the moment was upon us.
The launch teams had started inflation at 3 a.m. on March 1. The balloon was designed to function with a combination of hot air and helium. During the day the sun heats the helium, causing it to expand and make the balloon climb. At night propane is burned to heat the gas, maintaining the balloon’s lift.
Our meteorologists would work out the trajectories, then we would travel along with the moving weather all the way around the world.
As down broke, the wind began to blow and gust. Since any strong wind might damage the envelope and dash the gondola against the ground, we knew we had to take off soon.
At 8 a.m., Brian and I climbed in and closed the rear hatch. High above us the Mylar envelope was crackling. Hair-raising noises started to emanate from the gondola. Supplies and equipment kept tumbling onto the floor.
Unable to risk disaster any longer, Alan waited for one more big bounce and severed the restraining rope with his Swiss Army knife.
As we rose into the sky, he thousands who had assembled were screaming. Church bells were ringing. A fire engine’s siren was wailing. This enthusiasm seemed to propel us into the sky.
Brian: My first task was to be carried out atop the gondola, so before takeoff I climbed out through the top hatch and sat. a heavy double railing ringed the area, and we took off with such a jerk, I hat to cling tight to it.
Bertrand and I were both amazed by the speed at which we went up. The balloon finally stopped climbing at 1,000 feet when we hit an inversion layer—the level at which cold air close to the ground meets warmer air above. It acts like an invisible barrier.
Bertrand called out, “One bag of sand!” I started pouring 33 pounds of ballast down a tube that sent the sand clear of the capsule.
A moment later he shouted, “Look out, I’m going to burn!” The propane jets and blue flames roared six feet up, warming the helium. We started to climb again. I scrambled back into the gondola, and we sealed the hatch. We were on our way.
Bertrand: By sunset our first problems set in. the pilot lights on the burners began to act erratically, and every few seconds we had to manually ignite the burners.
More worrisome was the fact that we thought we were using far too much propane to maintain our height. It looked as though our chances of making it were perilously slim. But the first pair of fuel tanks held out until the evening of day two, exceeding our expectations. And that was a huge encouragement.
As we entered Moroccan airspace, I was rewarded by one of the most magnificent sights. I had ever seen: an absolutely incredible view of the Atlas Mountains with a full moon. We had been told how boring it would be to fly over the Sahara, but on the next day the views that unfolded were fabulous. For me, the desert was alive. The light was alive, and the sand was alive, full of different colors, different shapes, like the bottom of the sea. I spent hours staring at the desert, feeling its strangeness.
Brian: Early in the morning of March 4 the plan called for releasing our four empty auxiliary tanks. That meant an EVA—extravehicular activity—to cut them free. We also wanted to get rid of the ice that had formed from riding in the freezing high altitudes. As we descended to 10,000 feet, our adrenaline was flowing.
When we opened the hatch and climbed out, we found icicles that were ten feet long dangling from the envelope’s skirt. While I concentrated on fixing the faulty ignition system, Bertrand went about attacking the icicles with a fire ax. He commented that it was probably the first time that ice had rained on the Sahara in several thousand years.
With Bertrand holding one of my ankles, I reached out and freed one of the empty tanks. We watched it tumbling all the way to the ground. A puff of sand marked where it slammed into the desert. If it buried itself, I thought, it might lie there for a couple of millennia before some archeologist g it up.
By then we had finished our counterclockwise swing and were at last heading east, just as our meteorologists had predicted. The air was warm; the sky cloudless. Below us stretched sand and rock as far as the eye could see.
Bertrand: We were over Yemen and two days from the Indian subcontinent when an astonishing message came in from our ground crew: “The cable & Wireless control room says their balloon is landing 70 miles off the coast of Japan. The balloon iced up. Search and rescue are with them.” Now we were the only ones in the race.
I was desperate to pass on the news to Brian, and when he finally stuck his head out of the sleeping bunk hours later, I said, “I’ve got the most incredible news.”
He instantly said, “Andy’s down.”
Meanwhile I spoke to Luc, who confirmed that our position was perfect for enter China at the right point. We had guaranteed them we would keep south of 26 degrees latitude. If we found ourselves straying north of the limit, we would come down.
Brian: Heading for Myanmar (formerly Burma), we found we were graally creeping north toward the 26th parallel. This kept us on tenterhooks. But back in Geneva our weathermen were telling us we had to go right up almost to the boundary. Once there, the wind would take us e east.
On the way we had the following exchange with a Myanmar air controller.
Tower: “What is your departure point and destination?”
Me: “Departure point, Switzerland. Destination, northern Africa.”
Tower: (after several seconds of silence) “If you’re going from Switzerland to northern Africa, what in hell are you doing in Myanmar?”
Shortly before down on the morning of March 10 we arrived at the Chinese border. The Chinese had seen us coming and sent the message: “Your balloon’s heading for the prohibited zone. It must land.”
Bertrand: It was amazing. We skimmed across a 1,300-mile-long corridor straight as an arrow, with the 26th parallel never more than 30 miles away. Our meteorologists had sent us on a swirling trajectory of 8,100 miles, then through the eye of a needle.
By March 11 we were heading out over the Pacific. Faced by 8,000 miles of water, I felt as if I had stepped onto the edge of the abyss.
I picked up my pen and wrote: “This is exactly my definition of adventure, a point at which you hat to dig inside yourself to find the courage to deal with what may lie ahead.”
On Saturday, March 13, we were still over the Pacific. Our meteorologists said our speed would improve from our miserable 35 knots to 100 knots once we climbed into the jet stream. By Tuesday it would increase to 120.
Our propane reserves seemed perilously small. We had already burned two-thirds of our fuel and yet covered only half our course. everything depended on our weathermen: If they were right, we had a chance. If they were wrong, we were doomed.
Brian: Like Bertrand, I was thoroughly on edge over the Pacific. After seven days above the water, we at last made the coast of Mexico. Later that night, lying there, I found it had to breath. And it was not until I got up that I realized something was seriously wrong. I found Bertrand in the pilot’s seat, slumped against the bulkhead, gasping. He crawled into the bunk wearing an oxygen mask.
Our symptoms were not those of hypoxia, and the instruments monitoring the CO2 levels had not signaled any alarm. But despite this, we felt that we were slowing being asphyxiated. People on the ground started telephoning doctors in a frantic search for clues to what could be wrong with us. I was also wearing my oxygen mask, and after a few minutes of breathing pure oxygen, my head cleared. I thought, I Screw the instruments, and changed both the CO2 and the carbon filters. The symptoms graally began to disappear.
We crossed Mexico in a day and were soon out over the Caribbean. Reporting to air-traffic control in Kingston, Jamaica, I heard a female controller with a delicious voice ask what we were doing.
“We took off from Switzerland,” I answered. “We’re hoping to get around the world.”
“You guys sure are taking a chance!” she said.
She was right. Our fuel was critically short, and nobody was sure if we had enough to get across the Atlantic. Alan Nobel suggested we make our decision over Puerto Rico.
Bertrand: By March 18 it was time to decide. With cameras from all over the world focused on him, Alan got on the phone with us. When we had run through the agreed-upon formalities, Alan said, “I think you can go for it.”
“Bertrand!” cried Brian. “Tell him we’re going.”
“We’re not going to quit,” I told Alan. “Even if we ditch in mid-Atlantic, we go for it.”
Our weathermen guided us into the middle of the jet stream, and our speed increased as we shot out over the Atlantic. But cursing at 15,000 feet, the cold was intense and our heaters had failed. The temperature inside was 28.4 F, and our water supply froze.
On March 20 came good news. Our navigation computer told us we had made landfall. We had crossed the Atlantic, and at 6:15 GMT, or Greenwich Mean Time, when the sun came over the horizon, I again saw the desert I had loved so much 20 days earlier. Now the finish line was only 300 miles away, about three hours’ time.
When we crossed the line at 9:54 GMT, Brian and I stood up and embraced, slapping each other on the back and shouting, “We’ve done it! We’ve done it.”
The next morning, after the longest flight in distance and ration ever made by a free balloon, we landed in the Egyptian desert. Brian sent this fax: “The Eagle has landed. All okay. Bloody good.” Our trip round the world, and into history, was done.

梅格·德隆（Meg
Delong）在佐治亚州北部城镇盖恩斯维尔（Gainesville）读高中时，是一名认真的学生，着眼于大学。她的许多女友都朝着同一目标努力。但是她的弟弟和大多数男性朋友似乎更喜欢像福斯塔夫那样，而不是学习莎士比亚。
“很多人都认为学习是针对女孩的，”现在雅典佐治亚大学攻读法语专业的德隆说。 “他们真的很聪明，但是他们会变得愚蠢，而且似乎被老师接受了。”
以DeLong的经验为例，在全州的学校中将其乘以数千次，今年在她的校园里，新生班的女生比例接近61％也就不足为奇了。在大一英语教程中，一小群男人静静地坐着，而女性则主导着课堂讨论。但是在课外，校园的气氛显然是男性友好的。
Sigma Nu兄弟会的社交主席Tyler Willingham指出，在聚会上，即使没有约会的男人也可以从“许多漂亮的女人”中进行选择。
这种性别差距在美国各地的校园中日益明显。直到1979年，男子占大学生的大多数。随着妇女在社会上其他地方赢得越来越多的平等，很自然并且期望她们能够在大学里达到平等，这是她们在1980年代初期所做的。但是令人惊讶的是，自1992年以来，男子的高等教育入学率有所下降。目前，男子只占全国本科生的44％。联邦的预测显示，到2010年，他们所占的比例将缩小到仅42％。这种趋势是大学招生人员中最热门的辩论话题之一。一些私立文科学院已经悄悄地开始了特别的招募工作，包括招收男性。
为什么短缺？很少有事实，但是有很多理论。轶事证据表明，在不需要学士学位的高科技工作的诱惑下，男人比女人多。有人称这是比尔·盖茨综合症，是微软大学毕业生退学后的结果。但是高科技行业仅雇用了美国约9％的劳动力。近年来，在经济火爆的情况下，一大批男性，尤其是来自低收入家庭的男性，可能正从高中直接进入飞机维修，电话和电力线维修等领域，平均每周支付850美元而不是承担大量的大学债务。一些社会评论家指责在学校教师中缺乏男性榜样，并且是一种在男孩中提倡反智主义的文化。而且，尤其是在城市中心地区，犯罪和团伙诱使男孩多于女孩而不是女孩。
性别差距有多普遍？据爱荷华州奥斯卡洛萨市的教育分析师托马斯·莫滕森（Thomas
Mortenson）称，几十年来，男性所获得的大学学位的比例一直在下降。美国政府的数据显示，从1970年到1996年，随着女性所获得的学士学位数量增加了77％，男性所获得的数量却增长了19％。并非所有的学校都感到失衡。许多精英学院和大学的男女申请都在飙升。莫滕森说，但是总体数字应该使我们“醒来，看看男孩有麻烦了”。
杰奎琳·金（Jacqueline
King）是大学近期性别差距研究的作者，他强调指出，这种差距在黑人（最新数字为63％的女性到37％的男性），西班牙裔（57％到43％）中最为广泛，在她的分析中，低收入白人（54％至46％）。她说：“不是要上大学的中产阶级白人年轻人。”而且，老年妇女的入学人数激增，使人数进一步增加。
不过，莫滕森（Mortenson）引用了美国人口普查数据，该数据表明种族和收入群体之间的差距有所缩小。此外，他和其他人认为，男孩作为一个整体，在K-12成绩的许多阶段都落后于女孩：男孩往往会获得较低的成绩，并且不太可能获得高中文凭。他们在SAT上的分数略高，但只有65％的男生考上了大学，而女生则只有69％。
保守派教育分析师克里斯蒂娜·霍夫·索默斯（Christina Hoff
Sommers）在她最近的《反对男孩的战争》一书中写道，男生“通常被视为存在着性别不平等的原始存在者，潜在的骚扰者和永恒者”，并且“生活在谴责的阴影中”。索默斯（Sommers）引用的研究表明，男孩上学的准备要比女孩少，做功课少，被停职的频率更高。卫斯理大学招生副院长克利福德·桑顿说：“对于男性来说，成为一名纯朴的学生没有任何社会意义。”尽管最新数据显示，大学毕业生的平均收入几乎是没有大学的人的两倍，但“社会上许多男孩都认为上大学是一件麻烦事，”社会学家和作家迈克尔·金梅尔（Michael
Kimmel）说。 “当时的想法是，'没有这份工作我就可以得到一份工作。'”
考虑贾斯汀·斯帕格诺利（Justin
Spagnoli）。高中毕业后，他在社区大学上课，然后辞去父亲在佐治亚州罗伊斯顿的内阁商店工作。如今，25岁的Spagnoli的年薪为50,000美元，而他的伙伴刚刚完成大学学业，以较低的薪水工作。他说：“您不需要再急，”如果您有才华的话。
一些私立文理学院正在使男人更容易进入。在宾夕法尼亚州卡莱尔的狄金森学院，今年的新生班男生为43％，高于去年的36％，部分原因是该校偏向“合格男性候选人”，招生和学生生活副总裁罗伯特·马萨（Robert
Massa）说。这个想法在狄金森的学生中受到了不同的评价。物理学专业的米歇尔·爱德华兹（Michelle
Edwards）说：“它具有平权作用。”但是马萨强调说：“我们承认的男人和女人一样有资格。”
去年七月，佐治亚大学败诉了女学生提起的诉讼，这些女学生由于采取有利于男性的平等权利政策而被拒绝录取。 20岁的尚娜·诺里斯（Shanna
Norris）大三说：“男生比女生的体重增加（录取指数）是不公平的，但是如果校园里有更多的男生会更好。”
那如何招募更多的人呢？在北卡罗来纳大学教堂山分校，招聘人员大肆宣传数学和科学课程-传统上在男性应聘者中很受欢迎。芝加哥的德保罗大学（女性占59％）向男孩寄出了额外的邮件。
但是，如果公立大学试图招募更多男性，可能会面临法律挑战。在加利福尼亚州，严格的反肯定行动法规有效地阻止了基于性别的宣传。在得克萨斯州和佛罗里达州-都在很大程度上废除了招生政策中的优惠-州官员说，没有特别的计划来引诱更多的男人。许多学校仍在通过向代表性不足的学生提供空缺来平衡过去由一种性别主导的课程（如工程学和社会工作）。但这并不一定会增加西班牙裔男性的人数。这导致一些教育工作者放弃了招聘规则。在旧金山州立大学，种族研究教授罗伯托·哈罗（Roberto
Haro）经常在市中心地区的男孩俱乐部和中学招募少数男性。结果，他说：“在过去的一年中，我们看到已申请的少数民族男性人数略有增加。”
黑色兄弟会也参与其中。在马里兰州，阿尔法·皮皮·阿尔法（Alpha Phi
Alpha）的霍华德县校友分会为高中男性提供指导计划，帮助他们提高成绩并激发他们申请大学。计划负责人大卫·巴雷特（David
Barrett）说：“我们的许多男孩都在监狱中。在校男孩–他们承受着来自同龄人的巨大压力，无法在学业上取得卓越。我们想向他们展示学习是可以的。”
迈克尔·金梅尔（Michael
Kimmel）相信，一旦我们开始改变文化中的反智主义潮流，市场力量将有助于弥合性别差距。他说：“最终，人们将开始重返大学，以满足对受过良好教育的劳动力的需求。”意识到他们将被聪明有魅力的女性所包围，并且他们的收入前景很好，因此肯定还会吸引更多的男性进入校园。

参考：
CHICAGO (AP) _ Blogs are everywhere _ increasingly, the place where young people go to bare their souls, to vent, to gossip. And often they do so with unabashed fervor and little self-editing, posting their innermost thoughts for any number of Web surfers to see.
There is a freedom in it, as 23-year-old Allison Martin attests: "Since the people who read my blog are friends or acquaintances of mine, my philosophy is to be totally honest _ whether it's about how uncomfortable my panty hose are or my opinions about First Amendment law," says Martin, who lives in Elk Grove Village and has been blogging for four years.
Some are, however, finding that putting one's life online can have a price. A few bloggers, for instance, have been fired for writing about work on personal online journals. And Maya Marcel-Keyes, daughter of conservative politician Alan Keyes, discovered the trickiness of providing personal details online when her discussions on her blog about being a lesbian became an issue ring her father's recent run for a U.S. Senate seat in Illinois (he made anti-gay statements ring the campaign).
Experts say such incidents belong to a growing trend in which frank outpourings online are causing personal and public dramas, often taking on a life they wouldn't have if the Web had not come along and turned indivials into publishers.
Some also speculate that more scandalous blog entries _ especially those about partying and dating exploits _ will have ramifications down the road.
"I would bet that in the 2016 election, somebody's Facebook entry will come back to bite them," Steve Jones, head of the communications department at the University of Illinois at Chicago, says, referring to thefacebook.com, a networking site for college students and alumni that is something of a cross between a yearbook and a blog.
More traditional blog sites - which allow easy creation of a Web site with text, photos and often music - include Xanga, LiveJournal and MySpace. And they've gotten more popular in recent years, especially among the younger set.
Surveys completed in recent months by the Pew Internet & American Life Project found that nearly a fifth of teens who have access to the Web have their own blogs. And 38 percent of teens say they read other people's blogs.
By comparison, about a tenth of alts have their own blogs and a quarter say they read other people's online journals.
Amanda Lenhart, a researcher at Pew who tracks young people's Internet habits, says she's increasingly hearing stories about the perils of posting the equivalent of a diary online.
She heard from one man whose niece was a college student looking for a job. Out of curiosity, he typed his niece's name into a search engine and quickly found her blog, with a title that began "The Drunken Musings of ...."
"He wrote to her and said, 'You may want to think about taking this down,"' said Lenhart, chuckling.
Other times, the ease of posting unedited thoughts on the Web can be uglier, in part because of the speed with which the postings spread and multiply.
That's what happened at a middle school in Michigan last fall, when principals started receiving complaints from parents about some students' blog postings on Xanga. School officials couldn't do much about it. But when the students found out they were being monitored, a few posted threatening comments aimed at an assistant principal - and that led to some student suspensions.
"It was just a spiraling of downward emotions," says the school's principal. She spoke on the condition that she and her school not be identified, out of fear that being named would cause another Web frenzy.
"Kids just feed into to that and then more kids see it and so on," she says. "It's a negative power - but it's still a power."
Lenhart, the Pew researcher, likens blogs to the introction of the telephone and the effect it had on teen's ability to communicate in the last century. She agrees that the Web has "increased the scope" of young people's communication even more.
"But at the root of it, we're talking about behaviors middle-schoolers have engaged in through the millennia," Lenhart says. "The march of technology forward is hard, and it has consequences that we don't always see."
She says parents would be wise to familiarize themselves with online blogging sites and to pose questions to their children such as, "What is appropriate?" and "What is fair?" to post.
It's also important to discuss the dangers of giving out personal information online.
One Pew survey released this spring found that 79 percent of teens agreed that people their age aren't careful enough when giving out information about themselves online. And increasingly, Lenhart says, this applies to blogs.
Caitlin Hoistion, a 15-year-old in Neptune, N.J., says she knows people who go as far as posting their cell phone numbers on their blogs _ something she doesn't do. She also often shows her postings to her mom, which has helped her mom give her some space and privacy online.
"That's not to say if I thought something dangerous was going on, I wouldn't ever spy on her," says her mother, Melissa Hoistion. "But she has given me no need to do so."
Many college students say they're learning to take precautions on their own.
John Malloy, a 19-year-old student at Centre College in Danville, Ky., has put a "friends lock" on his LiveJournal site so only people with a password he supplies can view it.
"A lot of times, my blog is among the first places I turn when I am angry or frustrated, and I am often quite unfair in my assessment of my situation in these posts," Malloy says. "Do I wish I hadn't posted? Of course. But I haven't actually gone as far to take posts down."
Instead he makes them "private" so only he can read them.
"I like to keep them to look back on," he says.
Meanwhile, Joseph Milliron, a 23-year-old college student in California, says he's become more cautious about posting photos online because people sometimes "borrow" them for their own sites.
It's just one trend that's made Milliron rethink what he includes in his blog.
"I know this very conspiracy theorist _ but I wouldn't put it past a clever criminal to warehouse different databases and wait 20 years when all the Internet youth's indiscretions can be used for surreptitious purposes," says the senior at California State Polytechnic University, Pomona, who's been blogging for about three years.
Martin, the 23-year-old blogger in Elk Grove Village, agrees that blogs can "provide just one more avenue for a person to embarrass him or herself."
"They also make it easier for people to tell everyone what a jerk you are," says Martin, who'll be heading to graate school in Virginia this fall.
Still, she thinks blogging is worth it _ to stay in touch with friends and to air her more creative work, including essays.
"I suppose in that way," she says, "I think of blogs as 'open mic nights' online."

A desert is a beautiful land of silence and space. The sun shines, the wind blows, and time and space seem endless. Nothing is soft. The sand and rocks are hard, and many of the plants even have hard needles instead of leaves. The size and location(分布) of the world’s deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas develop. But within the last 100 yeas, deserts have been growing at a frightening speed. This is partly because of natural changes, but the greatest makers are humans.Humans can make deserts, but humans can also prevent their growth. Algeria Mauritania is planting a similar wall around Nouakchott, the capital. Iran puts a thin covering of petroleum(石油) on sandy areas and plants trees. The oil keeps the water and small trees in the land, and men on motorcycles(摩托车) keep the sheep and goats away. The USSR and India are building long canals to bring water to desert areas.

❾ 英语长篇阅读a healthy mind答案

A healthy mind is in a healthy body

quotation from John Jay tells us that we can’t have a healthy mind without a healthy body. This is true, especially to us, the middle school students.
As we see, many students are occupied in doing their homework and do not attach importance to taking regular physical exercise. Some of them often stay up late into the night and feel sleepy in classes. Others tend to go to school without breakfast. As days going on, their health becomes poorer and poorer. In this case, how can they centre on their studies and improve their studies?
Therefore, we must treasure our health. We must learn to make wise use of our time and take regular physical exercise. it’s extremely important for us to have enough sleep and a proper diet. Only in this way can we have a sound body, a healthy mind and a happy life.
