   holidays?

   comfortable. (2004福建)

   [解析]選A  本題考查insist表示“堅(jiān)持”時(shí)所帶的

賓語(yǔ)從句用虛擬,即:insist that sb. (should) do sth. 所以

本題選A。

9. -- Don't you think it necessary that he ____ to

   Miami but to New York?

   -- I agree, but the problem is ____ he has

   refused to. (2005  江蘇)

   A. will not be sent; that

   B. not be sent; that

   C. should not be sent; what

   D. should not send; what

   [解析]選B  本題既考查了虛擬語(yǔ)氣的用法,又考

查了表語(yǔ)從句的用法。由necessary引導(dǎo)的主語(yǔ)從句或賓

語(yǔ)從句,需要用shouId do,而他是要“被派往”邁阿密,所以

第一空用(should)not be sent,而第二空在be動(dòng)詞之后需

要用一個(gè)表語(yǔ)從句,由于句子結(jié)構(gòu)完整,所以用that。

   like to go to Tibet and travel through as much of

   it as possible. (2005湖北)

   A. would   B. could

   C. had to   D. ought to

   [解析]選B  本題考查if引導(dǎo)的虛擬語(yǔ)氣結(jié)構(gòu)。從

I'd like to go...判斷,本句為與現(xiàn)在事實(shí)相反,故選B。
