英语从句类型总结(共9篇)内容摘要：

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. (当 )我到了电影院时，电影已经开演了。 (从句的动作发生在主句之后，只能用 when,并要注意时态 ) He was about to leave, when the telephone rang. 他正要离开，忽然电话响了。 ( 此时不能放在句首。 主句动词一般表达 “正在” “即将” . while, as不能代替 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 ) 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 ) 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 ) 2. 由 till或 until引导的时间状语从句。 till 和 until 一般情况下两者可以互换，但是在强调句型中多用until。 并且要注意的是：如果主句中的谓语动词是瞬时动词时，必须用否 定形式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。 例如： I worked until he came。 I didn t work until he came。 3. 由 since 引导的时间状语从句。 since 引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。 一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时，表述为：现在完成时 +since+一般过去时。 但在 It is ＋时间＋ since 从句的句型中，主句多用一般现在时。 例如： It is five months since our boss was in 有五个月了。 知识扩展 1. It is „ since 从„ .以来多长时间了 It is five years since we met last time. 2. It is „ +before?(。 才。 ) It was a long time before I went to sleep again. It was an hour before(＝ until) the police arrived. 二 . 原因状语从句：在一个句子中作时间状语的句子。 连接词：由连词 because, since, as引导 , 也可由 for, now that 等词引导 didn’ t go to school yesterday because I was ill. 2. Since everybody is here, let’ s begin our meeting. 既然。 3. As you are in poor health, you should not stay up。 asked her to stay to tea, for I had something to tell her. .用法辨析： because , since , as , for辨析 1） because 语势最强，用来说明人所不知的原因，回答 why提出的问题。 当原因是显而易见的或已为人们所知，就用 a s或 since。 I didn’ t go, because I was afraid. Since /As the weather is so bad, we have to delay our journey. 2）由 because 引导的从句如果放在句末，且前面有逗号，则可 以用 for来代替。 但如果不是说明直接原因，而是多种情况加以推断，就只能用 for。 He is absent today, because / for he is ill. He must be ill, for he is absent today. 三、 条件状语 从句 连接词： if 如果 , unless (=if not)如果不、除非 (让步 ) it doesn’ t rain tomorrow, we will go hiking. will go to the party unless he goes there too. will be late unless you leave immediately. =If you don’ t leave immediately, you will be late. 条件状 语从句：主将从现 . He will not leave if it isn’ t fine tomorrow. 四、 目的、结果状语从句 目的状语从句是指在一个句子中充当目的状语的句子。 结果状语从句是指在一个句子中充当结果状语的句子 目的状语从句连接词 so that, so?that , in order that 引导。 结果状语从句连接词 so?that, such?that, so much/many?that 引导。 1. so?that如此 ?以至于 He always studied so hard that he made great progress. 2. so that 以至于 , 以便于 I’ ll run slowly so that you can catch up with me.

He is such a young boy that he can’ t go to school so +adj/adv.+ that， such +n.+ that 以上两种句型都表示结果 so为副词 ,后接形容词，副词原型，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. such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。 如果这名词是可数的 ,则必须在名词前加不定冠词a(an). 常见的形式是 :such a (beautiful)garden, such(nice)people. 五、 让步状语从句 让步状语从句是指在句子中作让步的状语的句子 连接词： though, although.， whether?or not 难点： though, although 当“虽然”讲 , 都不能和 but 连用 .
