5、了。 by the time i got to school, the class had already began.我到校时，已经开始上课了。 难点 as when while 的辨析 as when while 都表示主、从句动作同时发生，三者差异如下： as 表示 “一边。一边的意思 强调两个动作同时进行，并表示对比时 when 1、还可以表示 从句动词的动作在主几句动词的动作之前 或之后发生 。 2、 when and then; at that moment (正在那个时候 ) while 1、用于时间较长时 2、 强调两个动作同时进行，并表示对比时 有时这三个连词可以互换，有时不
6、可以。 lit was raining hard when (as) i got there. 我到那里时，正在下大雨。 ( 动作同时发生， when 可换为 as, 但不能换为 while，因为 get 是点动词 .) when i had read the article, he called me. 我看完这篇文章之后，她给我打了电话。 ( 从句动作发生在主句之前，注意时态表达，只能用 when ) when i got to the cinema, the film had begun.

7、态 ) she thought i was talking about her daughter, while, in fact, i was talking about my daughter. 他以为我在谈她女儿，然而，实际上在谈论我女儿。 (表转折，对比， when, as 都不能代替它 ) 考点 while the alien was buying a souvenir, the girl called the police. 外星人 买纪念品时，那女孩给警察打了电话。 (表示主句，从句的动作同时发生， while后引导的状语从句的动词必须是延续动词不能是点动词，因为它表示较长时间 )
8、考点 mother was worried because little alice was ill, especially as (when/ while) father was away. 妈妈担心，因为小爱丽丝病了，特别是他父亲不在家的时候。 (此时 as ,when, while 可通用 ) 知识扩展 1. it is since 从。以来多长时间了 (因为 since +从句或名词，表示一段时间 ) it is five years since we met last time.从我们上次见面已经五年了。 2. it is +before(。才 ) it was a long tim
9、e before i went to sleep again. 过了很长时间我才睡着。 it was an hour before( until) the police arrived. 过了一个小时，警察才来。 二、条件状语从句 要点： 表示状语从句由连词 if, unless (=if not) 引导。 1.if it doesnt rain tomorrow, we will go hiking. 如果明天不下雨 , 我们就去远足 . 2.you will get good grades if you study hard. 如果你努力学习 ,就会取得好成绩 . 3.i will go
10、to the party unless he goes there too. 我不会去参加聚会的 , 除非他也去 .(如果他不去 ,我也不去 .) 4.you will be late unless you leave immediately. 如果你不马上走 ,你将会迟到的 .(=if you dont leave immediately, you will be late.) 难点提示：用条件状语从句时 要注意时态的正确使用 ,当主句是将来时的时候 ,从句要用一般现在时 . he will not leave if it isnt fine tomorrow. 一般将来时， 一般现在时 t
11、hey are going to have a picnic if it doesnt rain next week. 一般将来时 , 一般现在时 考点 三、原因状语从句 要点 : 由连词 because, since, as 引导 , 也可由 for, now that 等词引导 1.i didnt go to school yesterday because i was ill. 我昨天没去上学，因为我生病了。 2. since everybody is here, lets begin our meeting. 既然大家都来了 , 让我们开始开会吧 . 3. as you are in

13、断 ),表示理由 . 四、地点状语从句 要点 : 由连词 where 和复合关 系词 wherever (=no matter where )引导 . 知识扩展 where there is a will , there is a way.有志者事竟成。 (谚语 ) 1.it will be mixed school where not all the children are disabled. 他将是一所混合式学校，那里的儿童并不都是残疾。 (在限定性定语从句中对限先行词起限定作用。 ) 2.wherever you go , i go too. 无论你到什么地方，我都 去。 (where

17、(目的 ) 难点 so that ,suchthat 都可以 in order that 两者皆可引导目的地状语从句和结果状语从句， 当他们引导 目的状语从句时，从句的谓语里常常有 can, could, may, might, will, would等次。 (见例句 2, 5 ) so +adj./adv.+ that， such +n.+ that 以上两种句型都表示结果 ,其中 so 为副词 ,后接形容词，副词原型，当可数名词前有 many, few；不可数名词前有 much, little 修饰时，应采用句型： so many (few, much, little )+n. 。 suc
18、h为形容词 , 后只能接名词。这名词既可以地可数的，也可以是不可数 的。如果这名词是可数 ,单数 ,则必须在名词前敬爱冠词 a(an). 常见的形式是 :such a (beautiful)garden, such(nice)people. the weather is so nice that id like to take a walk. 天气是如此只好 ,以至于我想去散散步 . mike is so honest a man that we all believe him. 麦克是如此诚实的一个人 ,以至于大家都相信他 live had so many falls that im bla

20、but 的格式是不对的 .但是他们都可以同 yet (still) 连用 . 所以 thought (although)yet(still)的格式是正确的 . wrong: although he is rich but he is not happy. right : although he is rich, yet he is not happy.虽然他很富有 , 然而他并不快乐 . right : although we have grown up, our parents treat us as children. right : although we have grown up,
21、our parents still treat us as children. 尽管我们已经长大了 ,可是我们的父母仍把我们看作小孩 . although, though 辨析 七、比较状语从句 要点：比较状语从句主要运用于形容词和副词的原级，比较级及最高级的句子之中。 1. asas 和。一样 jack is as tall as bob.捷克和汤姆一样高。 not so(as)as 和不一样 she is not so(as)outgoing as her sister 她不如她姐姐外向。 morethan (更 ) this book is more instructive than t
