重点句型：
1）While
一、while意为\"当......时候\",指一段时间,不能用来表示一个时间点。
Someone knocked at the door while I was cooking.
While the discussion was still going on, George came in. 当讨论还在进行时,乔治走了进来。
二、while意为\"而;然而\",表示转折。可以用作并列连词，表示对比意义，译为“而”，“却”。
Jane was dressed in blue, while Mary dressed in red. 珍妮穿蓝色衣服，而玛丽却穿红色衣服。
三、while意为\"虽然;尽管\",表示让步。=although
While I admit his good points, I can see his shortcomings. 尽管我承认他的优点,但我还是能看到他的缺点。
四、while意为\"只要\",表示条件。
We can surely overcome these difficulties while we are closely united. 只要我们紧密地团结一致,一定能克服这些困难。
五、while从句中的省略。
当while从句中的主语与主句的主语一致,且含有be的某种形式时,从句中的主语连同be可同时省略。
While listening to the radio, she fell asleep. 她在听收音机时睡着了。
While in London, he studied music and painting. 在伦敦时,他学习音乐和绘画。
While on his way here,在来这里的途中
He never dreams while asleep.他睡觉时总来不做梦。
六、while还可以用作从属连词，作“在……期间”，“当……时候”讲，使用时应注意它与用作从属连词的when的区别：
when引导的时间状语从句，即可表示“一段时间”，又可表示“一点时间”，因此从句的谓语动词既可以是延续性的，也可以是非延续性的。如：
①I hope to see you when(while)I stay in Beijing on business. (一段时间)当我出差北京时，希望见到你。
②When the clock struck twelve, all the lights went out. (一点时间)当钟敲响十二下时，灯全部熄灭了。
【注意】while引导的时间状语从句只能表示“一段时间”所以 while从句的谓语动词应是延续性动词(或状态动词)。例如：
①While I stayed(or was) in Shanghai, I saw her three times. 我在上海期间见到她三次。
如果从句的谓语动词是延续性的，可以用while也可以用when。例如：
②While(When) we were having a meeting, a stranger came in. 我们在开会时，一个陌生人走了进来。
七、while可用作名词,意为\"一会儿;一段时间\"。
作名词用时,主要用于短语中:
1. all the while一直，始终
2. all this(long) while长久,这阵子all this time；有好久for a long time
3. after a while过了一会儿
4. a short/little while ago方才
5. for a while=for a moment一会儿
6. in a little while不久, 没一会儿
7. between whiles时时；时常
8. once in a while=sometimes偶尔,间或
9. at whiles有时, 时常
10. every little while (=at whiles)有时, 时常
11. it’s worth (sb.’s) while to do(doing) sth.值得做
12. while the time away 消磨时间[while v.=pass]
13. make it worth your while=pay(you)

I looked everywhere for the letter, but it was in my pocket all the while. 我到处找那封信,却不知它一直在我口袋里。
2）What is it that Joe can’t find in the bathroom?
用It is／was…that／who…句型表示强调。
被强调的部分（通常是句子的主语、状语、宾语或宾语补足语）放在is／was的后面，如被强调的是人，则后面可用who，whom等代替。例如：
He met an old friend in the park yesterday. 他昨天在公园碰见一个老朋友。
上述句子可以通过强调句型对除谓语以外的不同成分进行强调。如：
It was he who/that met an old friend in the park yesterday. (强调主语)
It was an old friend that/who he met in the park yesterday. (强调宾语)
It was in the park that he met an old friend yesterday. (强调地点状语)
It was yesterday that he met an old friend in he park. (强调时间状语)
如果强调的是特殊疑问句，要用“特殊疑问词+is/was + it + that +…”结构，表示“究竟是谁……，到底在哪里……”等等。例如：
1. It is from the sun that we get light and heat.
2. It was not until I had read your letter that I understood the true state of affairs.
3. It was playing computer games that took the boy a lot of time that he ought to have spent on his lesson.

③but与一些固定结构连用。

2.except:指同一类事物的总体中除去一部分，强调的是除去。
如： He gets up early everyday except Sunday. 除星期天外，他每天早起。

i. any(+n.), anything, anyone, anybody, anywhere
ii. every(+n.),everything, everyone, everybody,everywhere
iii. no(+n.) nothing, no one, nobody, nowhere
iv. what who where
v. all

a great many等表示“许多”的词语
英语中有许多词语可用来表示“许多”，根据性质可分为三大类。
1)修饰可数名词复数形式的有 many, a good/great many, quite a few, a large (或great)/small number of等，其后的谓语动词用复数形式。如：
①A great/good many words and expressions have come into the language from American English.美国英语中的许多单词和短语进入了这门语言。

▲many和few, a few在句中可作定语、主语，但不能作表语。如只能说I have many/few books, 而不能说 My books are many/few.
▲very many相当于a great/good many, 在程度上比many要强。
▲a number of修饰主语时，谓语动词用复数形式，the number of…作主语时，谓语动词用单数。如：
⑤A number of students have done the work well. 许多学生作业做得很好。
⑥The number of the students in our school has risen this year. 今年我们学校学生的数量上升了。
句⑤的 A number of作定语修饰主语 students。句⑥的介语短语 of the students in our school作定语，修饰前面的主语 the number, 表示特指，students 前的冠词the不能省。
2)修饰不可数名词的有much, a great deal of, quite a little, an amount of等。其后的谓语动词用单数形式。如：
①He has spent much/quite a little/a great deal of/a large amount of money on his new house. 他在新房子上花费了许多钱。
②Much/A great deal/Quite a little has been done to stop the noise. 已采取了许多措施来制止污染。
▲much, a great deal和 many一样，可作定语或主语，而不能作表语，我们一般说 He has much/a great deal of money, 而不说 His money is much(或a great deal)。
▲a great deal后面不接名词时，不能用介词of。
3)既能修饰可数名词，又能修饰不可数名词的有 a lot of, lots of, plenty of, a great quantity of等，谓语动词根据主语是可数或不可数决定单复数形式。如：
①There are a lot of/lots of people in that room. 那个房间里有许多人。
②There\'s a lot of/lots of rice in the bag. 那只口袋里有许多大米。

原因状语从句表示主句动作发生的原因或理由。引导原因状语从句的连词有：because(因为)、as(由于)、since(既然)、now that(既然)等。例如：
I do it because I like it. 因为我喜欢我才干。
As(或Since、Now that)everybody has come, we can set off. 既然大家都到了，我们可以动身了。 As he is honest and modest, all his friends like him.因为他诚实、谦虚，所以他的朋友们都喜欢他。
1)because、since、as、for用法区别。
用because引导的原因状语从句时，主、从句可以体现出明显的因果关系，其重点在从句的原因上。because从句所表示的原因往往是人们不知道然而很想知道的原因。可放在句首或句末，并且语气最强，是唯一能回答why问题的连词。because从句也可以在对话中单独使用。例如：
He is absent today because he is ill.他今天缺席，因为他病了。
It was because he is ill that he is absent today.正是因为他病了，才没来。
since的语气比because弱，且其引导的从句多放在句首，其原因在说话人看来已很明显，或已为听话人所熟知，全句重点在主句上。since一般译为“既然”或“由于”。例如： Let's put off the meeting till tomorrow since so many people are absent.既然这么多人没来，我们就把会推到明天吧。
as和since引导原因状语从句，其含义差别不大，只是wince比as更正式。as表示原因的语气最弱，常用于口语中。例如：
Since(或As)I was afraid, I hid myself.由于害怕，我藏了起来。
As it is raining, you'd better take a taxi.既然现在下雨了，(所以)你最好乘出租汽车。
for常用作并列连词。它引导的句子只是对其前的内容加以解释或表示由产生的结果来推断造成这种结果的理由，而不表示直接因果关系。for一般放在全句后。例如：
It rained last night, for the ground is wet this morning. 昨夜下雨了，今早地都湿了。
(for引导的句子不表示“因为今晨地湿，所以昨晚下雨”的直接原因)
【注意】 相反，如果将原句改写成：
The ground is wet, for(或because) it rained last night.这里for和because都表示因果关系，可交替使用。
2)because一般不与reason连用，
一般不写成：The reason he is absent from work is because he is ill.
应写成He is absent from work because he is ill.或
The reason he is absent from work is that he is ill.他没上班，是因为他生病了。
3)以as、since、now that等引导的原因状语从句可以放在主句的前面或后面。放在主句前面是为了强调主句所表示的结果；放在主句后面，则强调从句所表示的原因。例如：
As he is working hard, he is likely to succeed.由于他工作努力，所以很可能成功。
He is likely to succeed as he is working hard.他大概会成功，因为他工作努力。
in that 既然，因为(引导原因状语从句)
Critism and self瞔ritism is necessary in that it helps us to correct our mistakes. 批评与自我批评是必要的，因为能帮助我们改正错误。
now that 既然(引导原因状语从句)
since 自从；因为(引导时间和原因状语从句)
