A.Come on! B.Take care!

【即境活用】
11. (高考安徽卷)—Could you be so kind as to close the window?
—________.
A.With pleasure B.Go ahead

D.That’s OK
解析:选A。问句的意思是“你可不可以好心把窗户关上?”这个情景是请对方做某事,所以回答不能用Go ahead,而是With pleasure(愿意)。

A.Forget it! B.That’s great!

14.The message is very important,so it is supposed________as soon as possible.
A.to be sentB.to send

D.sending

句型梳理
① 【教材原句】 It is hard to think of a world without metals.(P44)
很难想象一个没有金属的世界。
【句法分析】 本句中,it 为形式主语,真正的主语是不定式短语to think of...,构成It is/was+adj.+to do sth.的结构。
It is +adj.+for sb.to do sth.该句式中,作表语的形容词只能说明不定式的行为性质和特点,不能说明不定式的执行者。常见的这类形容词有:easy,important,difficult,hard,possible,impossible,necessary等。
It is+adj.+of sb.to do sth.该句式中,作表语的形容词表达不定式的逻辑主语的品行、性格或性质。常见的这类形容词有:kind,nice,good,honest,careful,careless,clever,wise,stupid,foolish,rude,polite,impolite等。
It is+adj./n.+thatclause
It is+no good/use doing sth.
①It is easier to say than to do.说比做容易。
②It is no good playing computer games.玩电脑游戏没有好处。
③It is a shame that he didn’t pass the exam.
很遗憾他没有通过考试。
④It is said that the tickets have been sold out.
据说票已售完。
15.(高考大纲全国卷Ⅱ)The doctor thought______would be good for you to have a holiday.
A.this B.that
C.one
D.it
解析:选D。句意:医生认为度假对你有好处。本题考查代词it作形式主语。根据句意不定式短语to have a holiday在宾语从句中作真正的主语,只有it 可作形式主语,故选D项。
【即境活用】
16.(高考天津卷)It is obvious to the students________they should get well prepared for their future.
A.as B.which
C.whether
D.that
解析:选D。句意是:对学生来说,很明显的是他们应该为将来做好准备。It是形式主语,________they should get well prepared for their future是主语从句,作真正的主语。这个引导词起引导作用,不作成分,故用that。
② 【教材原句】 Here is a table with the metals that react most at the top,and the metals that react least at the bottom.(P44)
这儿有一个图表,那些反应最强烈的金属在上部,反应最不强烈的在下部。
【句法分析】 这是一个倒装句,正常语序是:A table with...is here.
(1)在there ,here引导的句子中,谓语是be,exist等表示状态的不及物动词时,句子要全部倒装。
(2)在there,here,now,then,thus等开头的句子里,谓语动词是come,go,follow等时,句子要全部倒装。
(3)here,there引导的句子,当主语是代词时,不倒装,且此类句子不用进行时。
①Here are what I want you to do.下面是我想让你做的事情。
②There goes the bus. 公共汽车走了。
③Now comes my turn.现在该轮到我了。
17.(高考江苏卷)—Is everyone here?
—Not yet...Look,there________the rest of our guests!
?A.come
B.comes
C.is coming
D.are coming
解析:选A。句意:——都到了吗?——还没有……看,其余的客人过来了!本题考查主谓一致。本句中there放在句首,句子采用了倒装句式,谓语动词应该根据句子的主语the rest of our guests来判断,B项和C项为第三人称单数形式,可排除;come用于进行时态表示将来的动作,不合题意,可排除;A项谓语动词与主语一致,故答案为A。
【即境活用】
18.(高考福建卷)For a moment nothing happened.Then________all shouting together.
A.voices had come B.came voices
C.voices would come
D.did voices come
解析:选B。考查倒装结构。表示时间的副词now,then及表示方位的副词here,there等位于句首,与位移性动词come,go,arrive等连用,且主语不是人称代词,此时用完全倒装。从前一句可知此处描述的是过去的事情,所以用一般过去时。
