B. 新冠疫情个人防控预防措施,英语作文
2020 is a new beginning, but just at the time of the Spring Festival, the Chinese people once again face the virus crisis: new coronavirus, only 17 years since the last SARS in 2003. I saw in the news that the new virus caused by Wuhan as the source of infection spread to the whole country. According to statistics and analysis, the people who left Wuhan from January 10 to 22 and went to all parts of the country respectively arrived in Zhoukou, Yueyang, Yichang, Hefei, Chongqing, Nanning, Guangzhou and other places. This is an acute infection of pneumonia. The cause of the disease is that people eat
wild Chinese chrysanthemum head bat civet. This is a serious crisis. As human beings, shouldn't we reflect on it? If the epidemic cannot be controlled, where will human beings go? If we take good care of ourselves, will it happen? As for how to protect yourself, first of all, although the virus has become a focus, don't listen to all kinds of rumors at will,
scientifically prevent and control the sources of infection, cut off the transmission channels, and call on everyone to do a good job in personal protection, avoid going to crowded places, wear medical masks in public places, and pay attention to fast food hygiene. Wash hands frequently and drink more water. Try not to eat out and go out less. If you have fever or cough, please see a doctor in time. I hope that the people of the whole country will join hands to fight against this
crisis and stay at home and not run around. We can certainly survive this crisis from our motherland. It's very important that medical staff have given up the chance to celebrate the new year with their families and rushed to the front line of the epidemic field. We should believe them more! Come on Wuhan, come on angel in white, come on China, wish the beauty of the world be linked with you.
C. 如何预防电脑病毒
计算机病毒是一个程序，一段可执行码。就像生物病毒一样，具有自我繁殖、互相传染以及激活再生等生物病毒特征。
计算机病毒有独特的复制能力，它们能够快速蔓延，又常常难以根除。它们能把自身附着在各种类型的文件上，当文件被复制或从一个用户传送到另一个用户时，它们就随同文件一起蔓延开来。
如何预防计算机病毒：
程序或数据神秘地消失了，文件名不能辨认等；注意对系统文件、可执行文件和数据写保护；不使用来历不明的程序或数据；尽量不用软盘进行系统引导。
不轻易打开来历不明的电子邮件；使用新的计算机系统或软件时，先杀毒后使用；备份系统和参数，建立系统的应急计划等。安装杀毒软件。分类管理数据。
(3)怎么预防电脑病毒英语作文扩展阅读：
计算机病毒的特征：
1、繁殖性
计算机病毒可以像生物病毒一样进行繁殖，当正常程序运行时，它也进行运行自身复制，是否具有繁殖、感染的特征是判断某段程序为计算机病毒的首要条件。
2、破坏性
计算机中毒后，可能会导致正常的程序无法运行，把计算机内的文件删除或受到不同程度的损坏。破坏引导扇区及BIOS，硬件环境破坏。
3、传染性
计算机病毒传染性是指计算机病毒通过修改别的程序将自身的复制品或其变体传染到其它无毒的对象上，这些对象可以是一个程序也可以是系统中的某一个部件。
4、潜伏性
计算机病毒潜伏性是指计算机病毒可以依附于其它媒体寄生的能力，侵入后的病毒潜伏到条件成熟才发作， 会使电脑变慢。
5、隐蔽性
计算机病毒具有很强的隐蔽性，可以通过病毒软件检查出来少数，隐蔽性计算机病毒时隐时现、变化无常，这类病毒处理起来非常困难。
6、可触发性
编制计算机病毒的人，一般都为病毒程序设定了一些触发条件，例如，系统时钟的某个时间或日期、系统运行了某些程序等。一旦条件满足，计算机病毒就会“发作”，使系统遭到破坏。
D. 急求两篇关于噪音污染和电脑病毒的英语作文
噪音污染
We know the sounds of cities are loud enough to cause great harm to people's hearing in the U. S. One person out of twenty has got some hearing loss. And all over the world the situation is getting worse and worse all the time since the noise increases with the population.
With the development of machines, noise has also increased greatly in the 20th century. We live surrounded by loud planes, trucks and electric tools. TV sets and radios add up to 90 or J00 decibels, a certain unit used to measure the loudness of sound. A normal dialogue reaches 55 decibels; a plane goes to 100, and an ordinary train, reaching the station, can be twice as loud as the loudest plane. Disco music reaches about 118. At decibels the ear stops hearing sound, and pain starts. How terrible if things go on like this!
电脑病毒
Computer Virus
A computer virus is a computer program that can itself and infect a computer without permission or knowledge of the user. The original may modify the copies or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable medium such as a floppy disk, CD, or USB drive. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. A Trojan horse is a file that appears harmless until executed. In contrast to viruses, Trojan horses do not insert their code into other computer files. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms. Furthermore, some sources use an alternative terminology in which a virus is any form of self-replicating malware.
The term comes from the term virus in biology. A computer virus reproces by making (possibly modified) copies of itself in the computer's memory, storage, or over a network. This is similar to the way a biological virus works.
Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are not designed to do any damage, but simply replicate themselves and perhaps make their presence known by presenting text, video, or audio messages. Even these benign viruses can create problems for the computer user. They typically take up computer memory used by legitimate programs. As a result, they often cause erratic behavior and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.
There are many viruses operating in the general Internet today, and new ones are discovered every day.

The rich and powerful functionality and flexibility of operation, well hidden so that others are to be outshone by the back door. Client simple and convenient to operate so that the entry of just a beginner can act as hackers. When used in legal cases, the gray pigeon is a good remote control software. However, if some of it to do illegal things, gray pigeons have become very powerful hacking tool. This is like powder, on various occasions, brought different. Gray dove to the complete presentation may be only a gray pigeon author to make it clear that we are here only for a brief.
Gray Pigeon client and server are based on the preparation of Delphi. Hackers use of the client to configure a server program. Can be configured to include information on the type of line (for example, wait for the connection or take the initiative to connect), take the initiative to connect using the public network IP (domain name), a password to connect, the use of the port, the start of the name, the name of the service, the process of hidden ways, the use of the Shell, agents, icons and so on.
Server for the client to connect a variety of ways, making the environment in a variety of network users may be poisoning, including local area network users (Internet through a proxy), the public network and ADSL users to dial-up users.
As the gray dove to intercept the API call, in the normal mode file server and its services are registered to hide, that is to say, even if you set up a "show all hidden files" do not see them. In addition, the gray-end services doves of the file name can be customized, hand-All this has brought about the detection of certain difficulties. <br> However, through careful observation, we found that the detection of gray pigeons still have to follow the law. From the above analysis we can see that principle to run, regardless of the custom server-side file name is what will normally be installed in the operating system directory in order to generate a "_hook.dll" at the end of the document. Through this, we can more accurately detect the hand-gray-end services doves. <br> Due to the normal mode will hide their gray pigeons, so detection of gray pigeons must operate in a safe mode. Into the safe mode is: Start the computer in the Windows system into the start screen, press the F8 key (or in your computer holding down the Ctrl key), in the event of the start-up options menu, select "Safe Mode" Or "Safe Mode." <br> 1, dove gray as a result of the document itself has hidden attributes, so set Windows to show all files.

Open the Windows directory, there are really two documents at the same time there is a record for keyboard operation GameKey.dll document. <br> After a few steps which we operate on the basic of these documents can be gray-end services doves of the.
