19、從句的"簡化"現(xiàn)象常存在于以下五種狀語從句中:由if, unless等引導(dǎo)的條件狀語從句;由although, though, even if / though等引導(dǎo)的讓步狀語從句;由when, while, as, before, after, until / till等引導(dǎo)的時間狀語從句;由as, as if等引導(dǎo)的方式狀語從句;由as, than等引導(dǎo)的比較狀語從句。下面針對這五種情形作一歸納。 (1)當(dāng)狀語從句的主語是it,且謂語動詞是be時,it和be要完全簡化掉。例如: If (it is) possible, he will help you out of t

32、，又可以是瞬間動詞。并且when有時表示“就在那時”。 例如： When she came in, I stopped eating.她進(jìn)來時，我停止吃飯。(瞬間動詞) When I lived in the countryside, I used to carry some water for him.當(dāng)我住在農(nóng)村時，我常常為他擔(dān)水。（延續(xù)性的動詞） We were about to leave when he came in.我們就要離開，就在那時他進(jìn)來了。(瞬間動詞) While引導(dǎo)的從句的謂語動詞必須是延續(xù)性的，并強調(diào)主句和從句的動作同時發(fā)生（或者相對應(yīng)）。并且while有時還可以表示

34、） As we was going out, it began to snow.當(dāng)我們出門時，開始下雪了。（as強調(diào)句中兩個動作緊接著先后發(fā)生，而不強調(diào)開始下雪的特定時間） as when while的辨析as when while都表示主、從句動作同時發(fā)生，三者差異如下： 表示“一邊。一邊"的意思 as 強調(diào)兩個動作同時進(jìn)行，并表示對比時 用于發(fā)生時間較短時 when 1、還可以表示從句動詞的動作在主幾句動詞的動作"之前 "或"之后"發(fā)生。 2、when=and then; at that moment (正在那個時候) while 1、用于

38、e引導(dǎo)的從句不再用否定式的謂語，并且當(dāng)before引導(dǎo)的從句位于主句之后，有時譯成“就，才”。還要注意主句和從句之間的時間關(guān)系。當(dāng)主句用將來時，從句總是用現(xiàn)在時；如果before引導(dǎo)的從句謂語用的是過去時，則主句動詞多用過去完成時，這樣以便體現(xiàn)動作發(fā)生的先后。After表示主句動作發(fā)生在從句動作之后。主句和從句的動作的時間關(guān)系正好與before引導(dǎo)的從句相反。例如： It will be four days before they come back. 他們要過四天才能回來。 Einstein almost knocked me down before he saw me.愛因斯坦幾乎把我撞倒

41、sh.直到散會之后他才開始教我英語。 I worked until he came back.我工作到他回來為止。 I didn't work until he came back.他回來我這才開始工作。 Please wait until I arrived.在我到達(dá)之前請等我。 4.由since引導(dǎo)的時間狀語從句。since引導(dǎo)的從句的謂語動詞可以是延續(xù)性的動詞，又可以是瞬時動詞。一般情況下，從句謂語動詞用一般過去時，而主句的謂語動詞用現(xiàn)在完成時。但在It is +時間+since從句的句型中，主句多用一般現(xiàn)在時。例如： I have been in Beijing since y

45、ooner位于句首時，主句應(yīng)用倒裝語序。例如： He had no sooner arrived home than he was asked to start on another journey. 他剛到家，就被邀請開始另一旅程。 No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太陽剛從地平線上升起，他就起床勞動去了。 Hardly had I sat down when he stepped in.我剛坐下，他就進(jìn)來了。 He had hardly f
