　________ of the land in that district　 ________covered with trees and grass.

A. Two fifth...is　　 B. Two fifth...are　 C. Two fifths...is　 D. Two fifths...are

[解析]　 分数的分子用基数词，分母用序数词表示。如果分子大于1，序数词后加-s。分数和百分比作主语时，谓语动词的形式取决于分数和百分数后的名词。句子中的主语land是单数，所以谓语动词要用is covered。答案为C。　

6.

　________people in the world are sending information by e?mail every day.

A. Several million　 　B. Many million　　　 C. Several millions　 D.Many million

[解析]　 在million，hundred等前如果有具体数字或several等词时，要用单数形式。many一般不与million等词连用。在表示不确切数目时用复数，例如：表示“数百万”，英语为millions of。译文：每天，世界上有几十万人通过e?mail传递信息。答案为A。　

5.

As a result of destroying the forests, a large　 ________of desert　 ________

　covered the land.

A. number…has　　 　　B. quantity…has　　 C. number…have　　 D.quantity…have

[解析]　 a large number of后面要接复数名词，所以排除A、C。a large quantity表示单数，所以排除D。译文：破坏森林的结果是大片沙漠覆盖了陆地。答案为B。

4.

He is the only one of the students who _______a winner of scholarship for three years.

A. is　　　　 B. are　　　　 C. have been　　　　 D. has been

[解析]这是一个定语从句。在one前是否有定冠词决定定语从句中的谓语动词的单复数形式：one of the students中的先行词是the students，定语从句中的谓语动词要用复数形式。the only one of the students中的先行词是the only one，定语从句中的谓语动词要用单数形式。又因“for three years”是完成时的标志，所以答案为D。

3.

When and where to go for the on?salary holiday ________ yet.

A. are not decided　　　 　　　B. have not been decided

C. is not being decided　　　　 D. has not been decided

[解析]　 根据副词yet可确定用现在完成时。when and where to do sth.表示单数，要用has not been decided.答案为D。

2.

The house rent is expensive .I've got about half the space I had at home and I'm paying _________ here.

A. as three times much　　　　 B. as much three times

C. much as three times　　　　 D. three times as much

[解析]　 此题考察的是比较句的语序问题。对于比较句，“量”应放在谓语之后，as之前，因此选D。　

1.

He did it ________ it took me.

A. one-third a time　　　 　　B. one-third time

C.the one-third time　　　　　 D. one-third the time

[解析]　 考查倍数的说法。译文：他做这件事只用了我(做这件事)三分之一的时间。这句话带了一个定语从句，修饰the time，只是没有关系词。定语从句先行词为time,moment时，常不用关系词。如：The moment I saw him,I recognized him.答案为D。
