虛擬語氣
虛擬語氣也是一個(gè)難點(diǎn)。所謂虛擬語氣是表示說話人的愿望、假設(shè)、猜測或建議，而不表示客觀存在的事實(shí)。它通過句子的謂語動(dòng)詞的特殊形式來表示。現(xiàn)歸納如下：純假設(shè)，用虛擬，動(dòng)詞時(shí)態(tài)退一級：條件句，分主從，主句謂語前加would (should,could，might);表愿望,用虛擬，wish后面接賓語(從句)：現(xiàn)在過去與將來，動(dòng)詞時(shí)態(tài)退一級：提建議，用虛擬，賓語(從句)動(dòng)詞用(should)do：倆建議，三要求，再加堅(jiān)持與命令
(suggest,advise,demand,require,request,insist,order)：It is time和eoukd rather,后接叢句用虛擬：部分主語從句中， 謂語用虛擬結(jié)構(gòu) (It is necessry
/important/natural/natural/strange/strange that„„should do)。 下面舉例說明：
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.(表示愿望虛擬)
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(shí)間、天氣、環(huán)境等)
2.引導(dǎo)詞
A.作形式主語，代替由不定式、動(dòng)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(dòng)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(qiáng)調(diào)結(jié)構(gòu)：It is (was) +被強(qiáng)調(diào)部分+that (或who)…
注意：在強(qiáng)調(diào)結(jié)構(gòu)中，如被強(qiáng)調(diào)部分為時(shí)間狀語或地點(diǎn)狀語，其后的連接詞也絕不能為when 或where，而應(yīng)用that 。在復(fù)習(xí)中，一定要注意句式的不同。
It was in Shanghai that I bought the guitar.(that引起強(qiáng)調(diào)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(shí)間狀語從句)
It was at twelve o'clock that we arrived there.(that 引起強(qiáng)調(diào)句)
3. it，one，that 的區(qū)別：作為代詞，這三個(gè)詞的對比使用是高考的熱點(diǎn)之一。
—Why don't we take a little break? —Didn't we just have __________?
A.it B.that C.one D.this
The Parkers bought a new house but _________will need a lot of work before they can move in.
A.they B.it C.one D.which
