時間和原因狀語從句

AdverbialClausesofTimeUnit4Grammar(1)時間狀語從句：引導(dǎo)時間狀語從句的連詞有：when,while,as,before,after,till,until,since,assoonas,themoment,immediately,everytime,nexttime,thefirsttime,once等。

when,while,as表“當(dāng)...時”的異同

：

相同點(diǎn): 當(dāng)從句的謂語是延續(xù)性動詞時，三者常 可互換i.e.

When/While/Aswewerestilllaughing,theteachercamein.

不同點(diǎn): 1)when既表“時間段”又表“時間點(diǎn)”(=duringor atthetimethat),從句中動詞既可是終止性的， 也可是持續(xù)性的，還可表“正在這時”i.e.(1).WhenIarrivedthere,theywerewatching TV.

(2).

WhenIwasyoung,Ilikedsingingand dancing.

2)while只表“時間段”(=duringthetimethat),從句中動詞只限于持續(xù)性動詞，它有時含對照之意，表“然”而i.e. (1)Hefellasleepwhilehewasstudyinghisgrammarbook.

3)as用法與when相似，但它側(cè)重動作的同時性，表“一邊...一邊...”，還表“隨著”i.e. (1)Theytalkedastheywalked. (2)Astimegoesby,wegetwiser.1.when---正在…的時候，突然…

A.since B.whenC.as D.while2)______Iacceptthatheisnotperfect,Idoactuallyliketheperson.

A.While B.SinceC.BeforeD.Unless2.連接詞while的用法小結(jié)

1)while引導(dǎo)的動作必須是持續(xù)性的，側(cè)重主句動作和從句動作相對比。如：Pleasedon’ttalksoloudwhileothersareworking.2)while作為并列連詞，意為“而，卻”，表示對比。3)while可表示盡管，相當(dāng)于although。
