英语四级语法备考（3）

 　　1) It is demanded / necessary / a pity + that…结构中的主语从句的谓语动词要用should 加动词原形， should 可省略。

　　句型：

　　(1)suggested

　　It is　 (2)important　　that…+ (should) do

　　(3) a pity

　　(1)suggested, ordered, proposed², required,　 demanded, requested, insisted; + (should) do

　　(2)important, necessary, natural, strange

　　a pity,　 a shame,　 no wonder

　　(3)It is suggested that we (should) hold a meeting next week.

　　It is necessary that he (should) come to our meeting tomorrow.

　　2)在宾语从句中的应用

　　在表示命令、建议、要求等一类动词后面的从句中。

　　order, suggest, propose¹, require, demand, request, insist, command, insist + (should) do

　　I suggest that we (should) hold a meeting next week.

　　He insisted that he (should ) be sent there.

　　注意： 如suggest, insist不表示"建议" 或"坚持要某人做某事时"，即它们用于其本意"暗示、表明"、"坚持认为"时，宾语从句用陈述语气。

　　The guard at gate insisted that everybody obey the rules.

　　判断改错:

　　(错)　You pale face suggests that you (should) be ill.

　　(对)　 Your pale face suggests that you are ill.

　　(错)　 I insisted that you ( should) be wrong.

　　(对)　 I insisted that you were wrong.

　　3)在表语从句，同位语从句中的应用

　　My idea is that we (should) get more people to attend the conference⁴.

　　I make a proposal that we (should) hold a meeting next week.

　　Only in this way, can you learn English well.

　　Only after being asked three times did he come to the meeting.

　　如果句子为主从复合句，则主句倒装，从句不倒装

　　Only when he is seriously ill, does he ever stay in bed.

　　1) 表示允许或请求;表示没有把握的推测;may 放在句首，表示祝愿。

　　May God bless you!

　　He might be at home.

　　注意： might 表示推测时，不表示时态。只是可能性比may 小。

　　2) 成语： may/might as well，后面接不带to 的不定式，意为"不妨"。

　　If that is the case, we may as well try.

　　典型例题

　　Peter ___come with us tonight, but he isn‘t very sure yet.

　　A. must　　B. may　 C. can　 D. will

　　答案B. 表可能性只能用may.　此句意可从后半句推出。
