(同時(shí)) （持續(xù)性）When the movie ended, the people went back. （從先主后）2)while側(cè)重主從句動(dòng)作的對比，且從句的動(dòng)詞必須是持續(xù)性的。如：While we were chatting she was looking at the time table on the wall3)as引導(dǎo)從句時(shí)側(cè)重主從句動(dòng)作同時(shí)或幾乎同時(shí)進(jìn)行，從句的動(dòng)作可以是持續(xù)性的，也可以是短暫的。如：Sometimes I watch TV as I am having breakfast4）when和while還可以是并列連詞，意思分別是“就在這時(shí)”，“然而”。如：I was having a rest on the sofa when the telephone rangThey were surprised that a child should work out the problem while they couldnt .注：并列連詞when常用與以下句型中：was/were doingwhen（正在做突然）was/were about to dowhen（剛要做突然）was/were on the point of doingwhen(剛要做突然)had just donewhen.(剛一就)Hardly/Scarcely haddonewhen(剛一就)(2)before引導(dǎo)從句時(shí),詞義非常靈活，注意下列句子中的before的詞義：1.Before I could get in a word, the tailor had measured me.(還沒來得及就)2.We hadnt run a mile before he felt tired.(還沒就)3.We had sailed 4 days before we saw land.(才)4.Please write it down before you forget it.(趁還沒就)(3)till (until) 和nottill (until)1） till (until):主句謂語動(dòng)詞必須是持續(xù)性的，意思是“到為止“如：He remained there till/until she arrived.2） nottill (until): 主句謂語動(dòng)詞必須是短暫性的，意思是“直到才”如：She wont go to bed till/until he returns home.3） notuntil還有強(qiáng)調(diào)式和倒裝式：強(qiáng)調(diào)句：It is not until he returns home that she will go to bed.倒裝句：Not until he returns home will she go to bed.(4)幾個(gè)極易混淆的時(shí)間狀語從句：1） It was +時(shí)間點(diǎn)+when（當(dāng)?shù)臅r(shí)候時(shí)間是）It was 5 am when we arrived at the village.2） It was/will be+時(shí)間段+before(沒過就過了才)It was/will be two weeks before we met/meet again.3） It is /has been +時(shí)間段+since（自從以來有）It is/has been 3 years since we last met.突破點(diǎn)：一看be動(dòng)詞的時(shí)態(tài)，二看時(shí)間段還是時(shí)間點(diǎn)。注意：在“It is /has been +時(shí)間段+since”句型中，從句的動(dòng)詞必須是短暫性的，如果是延續(xù)性的動(dòng)詞，時(shí)間要從從句的動(dòng)作結(jié)束時(shí)算起。如：It is 3 years since I smoked.( 我戒煙有三年了)補(bǔ)充：as soon as, immediately, directly, instantly, the moment, the minute, the instant, no soonerthan, hardly/scarcely.when.和once這些從屬連接詞引導(dǎo)的從句都表示從句的動(dòng)作一發(fā)生，主句的動(dòng)作隨即就發(fā)生，常譯為“一就”。從句中一般時(shí)態(tài)代替將來時(shí)態(tài)。every time, each time, next time, the first time, any time, all the time等名詞短語用來引導(dǎo)時(shí)間狀語從句，表示“每當(dāng).，每次.；下次”等。練習(xí)題1.
