分数修饰名词做句子主语是,动词的数和名词保持一致.
the earth's surface是单数,动词也用单数形式,排除AB；
此句为客观事实,用一般现在时.
37.A
解释同上题,the students为可数名词复数,所以动词用复数形式,排除CD；
句子时态不太好判断,不过用一般现在时更好.
38.A
倍数表达法：倍数词twice + as + 形容词原级expensive + as...
其中后面的as...根据上下文,可以省略,此题原为as ours.
39.C/D
解释同上题,倍数表达法扩充句型：倍数词twice或more than twice + as + 形容词原级many + 名词vegetalbes + as...
楼主CD肯定打错了一项.
40.D
作为一个整体的population做句子主语时,动词用单数形式,排除AB；
句子时态不可能为过去完成时,排除C.
41.C
the moment是一个连词,等于as soon as,意思是“一...就...”.
42.C
be tired of...“对...厌倦”；
the boring speech “无聊的/令人厌烦的演讲”
43.改正：Because (of) the bad weather,mom forbade us to go to the countryside.
because是一个连词,引导原因状语从句.而the bad weather只是一个名词短语,不是状语从句,所以必须改用做介词的because of来引导.
44.B
in case of emergency “在紧急情况下”
42.B
since为连词,引导原因状语从句,意思是“既然”.
43.C
对why提问的疑问句,用because来引导答语.
