Ⅲ 九年级英语基本语法知识

呵呵 希望对你有所帮助 祝楼主进步哈
By是个很常用的介词（有时也用作副词），在初中英语中的用法有以下几种： 1.意为“在……旁”、“靠近”。如： Some are singing and dancing under a big tree . Some are drawing by the lake. 有的在大树下唱歌跳舞，有的在湖边画画儿。 2.意为“不迟于”、“到……时为止”。如： Your son will be all right by supper time. 你的儿子在晚饭前会好的。 How many English songs had you learned by the end of last term? 到上个学期末你们已经学了多少首英语歌曲？ 3.表示方法、手段，可译作“靠”、“用”、“凭借”、“通过”、“乘坐”等。如： The monkey was hanging from the tree by his tail and laughing.
猴子用尾巴吊在树上哈哈大笑。 The boy’s father was so thankful that he taught Edison how to send messages by railway telegraph.
孩子的父亲是那么的感激，于是他教爱迪生怎样通过铁路电报来传达信息。 4.表示“逐个”、“逐批”的意思。如： One by one they went past the table in the dark.
他们一个一个得在黑暗中经过这张桌子。5.表示“根据”、“按照”的意思。如：What time is it by your watch? 你的表几点了? 6.和take , hold等动词连用，说明接触身体的某一部分。如： I took him by the hand. 我拉住了它的手。 7.用于被动句中，表示行为主体，常译作“被”、“由”等。如： English is spoken by many people. 英语被许多人所说。（即“许多人讲英语。”） 8.组成其它短语。 1) by the way : 意为“顺便说”、“顺便问一下”，常做插入语。如： By the way , where’s Li Ping , do you know?
顺便问一下，李平在哪儿。你知道吗？ 2) by oneself : 意为“单独”、“自行”。如： I can’t leave her by herself. 我不能把她单独留下。 3) by and by : 意为“不久以后”、“不一会儿”。如： But by and by , more and more people began to study English. 但是不久以后，越来越多的人开始学英语了。
二、动名词的构成动词后加动名词doing，相当于名词，在句子中可以做主语、宾语、表语定语等。1）★作主语（这种用法常考）
Fighting broke out between the South and the North.南方与北方开战了。2）作宾语Would you mind turning down your radio a little, please?
请问你介意调小一点收音机的音量吗？3）作表语Babysister’s job is washing，cooking and taking care of the children。保姆的工作是洗衣服，作饭和照看孩子。
Unit2
used to 的用法：（1）肯定句：used这个词没有人称的变化，to后面接动词原形。 否定句是didn’t use to….
When I was a child, I didn’t use to like apples.当我还是孩子的时候我不喜欢苹果.
疑问形式是Did you use to…?Where did you use to live before you came here?当你来这儿之前你住哪儿？
（2）含有used to 的句子的反意疑问句不要usedn’t + 主语，而用didn’t ＋ 主语。He used to smoke, didn’t he? 他过去常常吸烟，是吗？Yes, he did./ No, he didn’t. 是的，他吸。/ 不，他不吸。
（3）used to 表示过去的习惯动作， 而不是现在的。I am used to the weather here. 我已经习惯于这里的天气了。He is used to hard work. 他习惯于艰苦的工作。
（4）used to 可以和be, have 以及其他状态动词连用，描写过去的状态。 I used to be a waiter, but now I’m a taxi-driver.我过去是一个服务员，但现在我是出租车司机。
★ 本单元的许多运用used to 的句子属于描述过去的状态。Mario used to be short. 马力奥过去总是很矮。Amy used to be outgoing. 爱米过去性格外向。Tina used to have long and straight hair.蒂娜过去有一头直的长头发。He used to wear black shoes. 他过去常穿黑鞋。
Unit3
本单元重点讲到了被动语态的用法 英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态，人称和数的变化，其变化规则与连系动词be完全一样。
 一、被动语态的句式变化：
Unit4
虚拟语气：如果我们所说的不是事实，也不是要求、命令、劝告等，而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气
注意：条件句分两种，真实条件句和虚拟条件句。只有在虚拟（非真实）条件句中，才用虚拟语气，而在真实条件句中，要用陈述语气。
请比较：
（1）If it is sunny tomorrow , we’ll go to the zoo.
如果明天天气好，我们将会去公园。在这句话中，明天天气好是完全有可能实现的，并非虚拟、幻想，因此是真实条件句。在本句中，适用“主将从现。”
（2）If I were you , I would go at once.
（如果我是你的话，我立刻就走。）在这句话中，条件句，“如果我是你”，但事实上，我不可能成为你，这只是假设的情况，没有实现的可能。当条件实现的可能性很小，甚至可以说没有时，就需要用虚拟语气来表示，动词发生了变化。
也就是说虚拟语气表示和现实的事实相反时，从句用一般过时。
主句用 “should/would/could/ might +动词原形。
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in the bank.
知识点2. He doesn’t know if he should bring a present.
此处if表示“是否”，引导宾语从句。Should此处表示“应该”。不是虚拟语气。
E.g.1. I don’t know if I should go to the party.
2.If I have enough money, I will go to Hainan .
知识点3.If I were you , I’d wear a shirt and tie.
if 引导的条件状语从句表示与现在事实相反的虚拟语气时，be动词只能用were，而不能用was。
E.g. If he were here, he would not agree with you .
知识点4. I don’t have a present. What if everyone else brings a present?
What if… “如果……怎么办？”相当于 what would happen if…
E.g. What shall I do if it snows?
知识点5.Well, dogs can be a lot of trouble.
Trouble 麻烦事 ,名词
常用搭配 ：get (sb)into trouble get out of trouble what’s the trouble
定语从句
1. who 指人,作主语或宾语 (作宾语可省略）
The man who I talked with is our teacher.
A person who steals things is called a thief.
2. whom指人,作宾语 (作宾语可省略,如介词提前则不能省)
The man (whom/who) I nodded to is Mr. Li.
The man to whom I nodded is Professor Li.
3. which 指物，作主语或宾语 (作宾语可省略, 如介词提前则不能省)
These are the trees which were planted last year.
This recorder （which） he is using is made in Japan.
Is this the library (which) you borrow books from?
Is this the library from which you borrow books?
4. that 指人/物，作主语或宾语 (作宾语可省略）
A plane is a machine. It can fly.→A plane is a machine that can fly.
He is the man. I told you about him. →He is the man (that) I told you about.
The scientist is very famous in the world. We met her yesterday.
↓
The scientist Ø we met yesterday is very famous in the world.
who
whom
that
The dress is new. She is wearing it.
↓
The dress that she is wearing is new.
which
Ø
(3) He is the kind person. I have ever worked with him.
↓
He is the kind person that I have ever worked with.
who
whom
Ø
This is the best film. I have ever seen this film.
↓
This is the best film that I have ever seen.
Ø
在选择引导定语从句的关系代词时，有如下要点：
1 由于关系代词在主句与从句间既起到联系作用，又在从句中充当一个成分，因此， 要正确判断关系代词在从句中的功能，如作主语还是宾语等。
2 当先行词指人时，关系代词可用who（做主语，宾语），that（做主语，宾语），whom（作宾语），whose（作定语）
3 当先行词指物时，关系代词可用that（做主语，宾语），which（做主语，宾语）
4 再定语从句中，作宾语的关系代词长可省略，但在介词后面的关系代词不能省略。指人时，介词后只用whom，指物时，介词后只用which。
5 在非限制性定语从句中，指人时，只用who，指物时，只用which。Unit8
1、短语动词小结
常见短语动词结构有下面几种：
1.动词+副词 如：give up 放弃 turn off 关掉 stay up 熬夜
这种结构有时相当于及物动词，如果其宾语是代词，就必须放在动词和副词之间，如果是名词，则既可插在动词和副词之间，也可放 在短语动词后。
2. 动词+介词 如：listen of 听 look at 看 belong to 属于
这种结构相当于及物动词，后面跟宾语。
3. 动词+副词+介词 如：come up with 提出，想出 run out of 用完，耗尽
4. 动词+名词(介词) 如：take part in参加 catch hold of 抓住
2、倒装句
not only … but (also) … 不但… 而且… 用来连接两个并列的成分
(1)引导以 not only …but (also)… 开头的句子往往引起部分倒装。
因此 ⑴Not only do I feel good but (also)…. 是倒装句。也是说得要
把前面的句子中的助动词或者是情态动词放在主语的前面。如：
①Not only can I do it but (also) I can do best. 我不仅能做到而且做得最好。
⑵Not only…but (also)… 接两主语时，谓语动词随后面的主语人称和数的变化 也就是就近原则 如：
①Not only Lily but (also) you like cat. 不仅莉莉而且你也喜欢猫。
②Not only you but (also) Lily likes cat. 不仅你而且莉莉喜欢猫。
常见的就近原则的结构有：
Neither… nor…即不…也不… (两者都不)
Neither you nor I like him. 我和你都不喜欢他。
Either… or… 不是…就是… (两者中的一个)
Either Lily or you are a student.
Not only …but (also)…

被动语态
被动语态基本用法：当句子的主语是动作的执行者时，谓语的形式是主动语态。当句子的主语是动作的承受者时，谓语要用被动语态。被动语态由助动词be+过去分词构成，时态通过be表现出来。
被动语态基本结构：be+及物动词的过去分词 (如果是不用物动词，其过去分词应带有相应的介词)
各种时态的被动语态构成
一般现在时：S（主语）+am/is /are +P.P（动词的过去分词）
一般过去时：S+was/were +P.P.
情态动词：S+ can/may/must/should + be+ P.P.
一般将来时：S+ will+be+ P.P.
现在进行时：S+am/is /are+being +P.P
现在完成时：S+ have/has + been+ P.P.
过去进行时：S+ was/were+being+ P.P.
被动语态基本结构：be+及物动词的过去分词
(如果是不用物动词，其过去分词应带有相应的介词)
被动语态中的be 是助动词，有人称、数和时态的变化。
被动语态中动作的发出者或执行者做介词by的宾语，放在句末，by 表示“由，被”的意思
汉语中含有“据说”、“据悉”、“有人说”、“大家说”等时。例如：
It is believed that …… 人们认为 …… It is said that …… 据说 ……
It is thought that …… 人们认为 …… It is known that …… 众所周知 ……
It is reported that ……据报道 …… It is proved that ……据证明 ……
It is announced that ……据宣布 …… It is suggested that ……据建议 ……
It is requested that ……据要求 …… It is demanded that ……据要求 ……

Unit 11 Could you please tell me where the restrooms are ?
1、宾语从句
A.宾语从句：宾语从句在复合句中作主句的宾语，引导宾语从句的关联词有that, if/whether, what, who, whose, which, why, when, where, how等。
1、连接词
1)由连接词that引导陈述句，在口语中that常省略。
eg. He said that he would like to see the headmaster.
2)由连接词whether/if引导一般疑问句，whether和if 常可互换，但下列场合一般用whether.
①介词后的宾语从句：I'm thinking of whether he'll come.
②与or not连用：I don't know whether I should go or not.
3)由连接代词what, who(whom，whose)which或连接副词when, where, why，how引导特殊疑问句。 eg. Do you know who/whom she is waiting for?
2、语序：
不管宾语从句是陈述句、一般疑问句或特殊疑问句，都要用陈述句语序，也就是说主谓次序不能颠倒。连接词＋主谓结构
(1).Bill wanted to know who did this. (2).I don't know what's the matter with Bob?
(3).I don't know what's wrong with them?
3、时态：
一般说来，主从句时态要统一。如果主句是一般现在时，从句可根据需要用其它任何时态；如果主句是一般过去时，从句应该用相应的过去时态范畴（也就是用一般过去时，过去进行时，过去将来时，过去完成时）。
eg.①Lily wanted to know whether her grandma liked the handbag. ②I asked the teacher where we would have the meeting. ③Could you tell me how I can get to the zoo?
如果从句表明的是一个客观事实或真理，那么无论主句是什么时态，从句都只能用一般现在时。 eg. The teacher told us that light travels much faster than sound.
注意：在think后的宾语从句，如果需要表示否定意义，一般不在宾语从句中否定，而是在主句中否定。 eg. I don’t think that English is easy. I think that English is not easy. ( 误)
Could you tell me how to get to the park?
请你告诉我怎么才能去邮局好吗？中的how to get to the park
是疑问词与动词不定式连用，用作宾语，但不是宾语从句，可是
相当于how I can get to the park（宾语从句）如：
I don’t know how to solve the problem. ==
I don’t know how I can solve the problem.我不知道如何解决这个问题
Can you tell me when to leave? ==
Can you tell me when I ill leave? 你能告诉我什么时候离开？

Unit12 You are supposed to shake hands.
should have asked”是“情态动词＋现在完成时”表示过去本应该做某事，事实上没有做
I find it difficult to remember everything.

形式宾语 真正宾语

常见的形式宾语有：
find / think + it/them +形容词 to do sth. 如：
I think it hard to study English.
Unit 13 Rainy days make me sad.
make sb./sth. + adj. 使某人（感到），使……处于某种状态
（make的宾语之后可跟名词，形容词，分词来充当宾语的补足语）
make sb. / sth. + do …使某人做某事（不能带不定式符号to）
make it 习惯用语，及时赶到，到达目的地
make of /from./out of
★Make of 原材料制成成品后，原材料未经任何化学变化，仍保持原有性质. 例如： The chair is made of wood. At first people believed that air was made of only one gas.★Make from 当原材料制成成品后，经过了化学变化，失去了原有性质.
make up of 常用于被动结构：be made up of相当于consist of（由…组成） make up from 由…所制造
Unit 14 Have you packed yet?
现在完成时是由“助动词have（has）+动词过去分词”构成。
用法: 1.表示过去发生的某一动作对现在造成的影响或结果,常与一些时间状语,如:already, yet, ever, never, just, before, once, twice等连用,也可以和包括现在在内的时间状语,如these days, today, this year, so far等连用.eg.I have already posted the letter. (信已经不在我这儿了)
★注意：在这里要注意already和yet的辨析:
★①already通常用于肯定句。 I have already told him.我已经告诉他了.  I have already put it in my suitcase. 我已经把它放进我的手提箱了.
★②yet常用于疑问句和否定句。 ----Have you watered the tree yet? 你浇树了吗?  ----Yes，I have already watered it. 我浇了. ----Have you fed the dog? 你喂过狗了吗?  ----No. I haven’t fed it yet.没有，我没喂. 2.表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段,since+时间点/从句, in the last ten years等,谓语只可用延续性动词.
解析： 1.英语动词根据词义可分为两种,一种是延续性的,一种是终止性的,终止性动词(也可称为非延续性动词,瞬间动词,或点动词),如begin,start,die,buy,leave, come等,表示动作的发生与结束于一瞬间完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+时间段, since+时间点/从句连用,也不能用在how long引导的特殊疑问句中.
eg. I've left Shanghai for three days.(×) I've been away from Shanghai for three days.( √ ).
I left Shanghai three days ago. ( √ ) It is /has been three days since I left Shanghai.( √ )
2.初中英语课本中常见终止性动词有:leave, go, come, arrive, begin, buy, borrow, die, join, become等.终止性动词要表示持续时, 可用以下方法:
⑴.将时间状语改为时间段 + ago,句中谓语动词用一般过去时.
eg.我弟弟参军两年了. My brother joined the army two years ago.
⑵.若保留for+时间段,since+时间点/从句, 或用在 how long 句型中,则需将终止性动词改为相应的状态动词或延续性动词
★常见终止性动词与延续性动词(或状态动词)的对应关系如下：
come/go/arrive/get/reach/move------be in/at open-----be open
die------be dead close----be closed become---be borrow---keep begin/start-----be on put on----wear leave-----be away (from)
buy-----have fall asleep----be asleep end/finish-----be over
catch a cold-----have a cold join the army----be in the army be a soldier
join the Party----be in the Party be a Party member
→My brother has been in the army for two years. →My brother has been a soldier for two years.
3.现在完成时中been to, gone to和been in/at been to去过某地,表示某人的一种经历,可以和once, twice, already, ever, never等连用.
4.现在完成时中的 for 与 since
for + 时间段 与延续性动词的现在完成时连用 since + 时间点/从句
I have kept the library book for a week.= I have kept the library book since a week ago. 5. It is /has been +一段时间 + since 从句.自从某事发生已有一段时间了. eg. It is /has been two years since my brother joined the army. 注意:1.since 引导的从句中动词用过去时
2.when 引导 的特殊问句不与现在完成时连用.
3.have got,has got 虽然是现在完成时,但have got=have has got==has

Various bacteria survive in different environment, and through different approach spread. A statistics, the upper body in people per square centimeter skin is 50 a 5,000 microbes, they get from the sweat and the secretion of a growth, reproction nutrition, death metabolism. Sweat or the fatty acid, lactic acid secretion inside can kill many organisms. What of microbiology could have also killed or disaster live action, constitutes the balance coordination of nature. Microbial were widespread, even though they live on human proction have certain positive role, but they also often make instrial equipment from corrosion, make food and raw material of corruption and metamorphism, even with food for the media to cause human body poisoning, disease, cancer and death.

1, microbial role

1.1 microorganisms in the role of material circulation in biosphere material circulation process, mainly with different type of microbial organic decomposers in the process of mineral play an irreplaceable role in procers together, it pushes the material circulation, biological inside that ecosystem balance. For example, in the carbon cycle, on the earth, 90% of the co 2 is proced by microbial life activities; In nitrogen cycle, nitrogen fixation function, amination function, nitrification, denitrifying action have the action of microorganisms; In phosphorus and sulfur cycle in the same also need various microbes activities.

1.2 microorganism and sewage treatment instry rapid development of also has brought people certain environmental pollution. In many of the sewage and waste water treatment method, biological treatment because of its economic convenient, good effect is prominent advantages and has been widely used. In the wastewater treatment process of biology, microbiology plays a particularly important role in water, they can turn organic carbon decomposed into CO 2, H 2 s, CH 4 gas, such as; Will contain nitrogen organic material is decomposed into ammonia, nitric acid, proposed and nitrogen; Can make mercury, arsenic of human toxic heavy metal salt in water in transformation, in order to remove, make many recycling or pathogenic sex parasites often die because of and environmental discomfort.

130 be beneficial to human body health human intestinal contains a variety of microbes, which mainly has e. coli, proce gas bacillus, deformation bacteria, ng proce alkali bacteria, compared with perfringens spindle bacteria, lactobacillus and helicoid, etc. The human body for these microbes provides good perched place, and these bacteria living in intestinal can synthetic lactoflavin, vitamin B12 vitamin K and so on many kinds of vitamins and amino acids for the body to absorb use.

There are many food (such as 1.4 soy sauce, vinegar, monosodium glutamate, wine, yogurt and cheese, mushrooms), instrial goods (such as leather, textile, petrochemical), drugs (such as antibiotics and vaccines, vitamin, ecological pesticide) is dependent on microbial manufacturing; Microorganisms in mineral exploration and mining, waste disposal (water purification, biogas fermentation) in various fields such as also play an important role. Microbes are only the nature of cognitive nitrogen-fixing (such as rhizobium fredii) of plants and animals resies of people (such as cellulose degradation in common, and degradation) at the end of the chain, thus finish first ends carbon, nitrogen, and sulfur and phosphorus in the cohesion theory of biomass. If there is no microbes, many biological lose the necessary nutrients to source, plant fiber resies cannot decompose and the infinite accumulation, there is no nature current prosperity and order or human generation and dimension renewal.

1.5 microorganism and closely related to human health. Most microbes to the human body is harmless. In fact, the human body outer surfaces (such as skin) and the inner surface (such as bowel) live many normal, beneficial bacterium group. They hold these surface and proce natural antibiotic, restrain harmful bacterium landing and growth; They also assist absorption or personally manufacturing some human body essential nutrients, such as vitamins and amino acids. The flora of disorders (such as antibiotic abuse) can lead to infection or nutritional deficiencies. But on the other hand, human and animal and plant diseases and many are caused by microorganisms, these microbes pathogenic microorganism called pathogenic microorganism (or pathogen (pathogen)
