虛擬語氣

虛擬語氣也是一個難點。所謂虛擬語氣是表示説話人的願望、假設、猜測或建議，而不表示客觀存在的事實。它通過句子的謂語動詞的特殊形式來表示。現歸納如下：純假設，用虛擬，動詞時態退一級：條件句，分主從，主句謂語前加would (should,could，might);表願望,用虛擬，wish後面接賓語(從句)：現在過去與將來，動詞時態退一級：提建議，用虛擬，賓語(從句)動詞用(should)do：倆建議，三要求，再加堅持與命令

(suggest,advise,demand,require,request,insist,order)：It is time和eoukd rather,後接叢句用虛擬：部分主語從句中， 謂語用虛擬結構 (It is necessry

/important/natural/natural/strange/strange that„„should do)。 下面舉例説明：

A、If you came tomorrow,we would have the metting. (條件句虛擬)

B、Without air,there would be no living things.(同上)

C、We wish we had arrived there two hours earlier.(表示願望虛擬)

D、He demanded that we (should)start right away.(表示建議虛擬)

E、It is(high)time that we left (should leave)now.(特殊從句虛擬)

F、I would rather you gave me the book.(同上)

G、It is necessary that we should clean the room everyday，(主語從句虛擬) H、He speaks English so fluently as if he were English. (特殊從句虛擬)

一、 it的.用法

1.作人稱代詞

John likes playing Ping pong./ He always does it in the afternoon.(指代上下文提到的事物); /It's time we went home. / How far is it from here to your home ? / It is getting warmer and warmer./ It's very quiet at the moment.(可指時間、天氣、環境等)

2.引導詞

A.作形式主語，代替由不定式、動名詞或從句表示的真正主語。

It's important for us to learn a second language./ It's no use talking to him./ It's known to all that the earth goes round the sun.

B.作形式賓語，代替由不定式、動名詞或從句表示的真正賓語。

We feel it our duty to help others./ He made it clear that he would leave the city.

C.強調結構：It is (was) +被強調部分+that (或who)…

注意：在強調結構中，如被強調部分為時間狀語或地點狀語，其後的連接詞也絕不能為when 或where，而應用that 。在複習中，一定要注意句式的不同。

It was in Shanghai that I bought the guitar.(that引起強調句)

It was Shanghai where I bought the guitar.(where引起定從)

It was twelve o'clock when we arrived there.(when引起時間狀語從句)

It was at twelve o'clock that we arrived there.(that 引起強調句)

3. it，one，that 的區別：作為代詞，這三個詞的對比使用是大學聯考的熱點之一。

—Why don't we take a little break? —Didn't we just have __________?

The Parkers bought a new house but _________will need a lot of work before they can move in.
