例1、I earn 10 dollars_________ hour as _________ supermarket cashier on Saturdays.

A. a...an    B. the...a     C. an...a    D. an...the

答案为C。

[解析] hour以元音开头,前面加不定冠词an,an hour“每小时”;a表示“一个”,放在supermarket cashier前面表示类指,说明属哪类人。译文:星期六我作为超市出纳员每小时挣10美元。a/an的用法规则:以元音音素开头的单词前用an,以辅音音素开头的单词前用a。

例2、One way to understand thousands of new words is to gain________ good  knowledge of basic word formation.

A. /     B. the     C. a     D. one

答案为C。

[解析] knowledge是不可数名词,当被某些修饰语修饰时,前面要加不定冠词,如:He has a very good knowledge of English.他在英语方面有丰富的知识。

例3、Alexander Graham Bell invented ________telephone in 1876.

A. /   B. a   C. the   D. one

例4、The cakes are delicious. He'd like to have ________ third one because _______ second one is rather too small.

A. a…a    B. the…the     C. a…the    D. the…a

答案为C。

[解析] 注意序数词前面的冠词的用法:当序数词表示顺序时用定冠词the;表示再来一次使用不定冠词a (an)。从句子的意思可知,third one表示再吃一个,所以填a;second one表示所吃的第二个,所以填the。这句话的意思是:蛋糕很好吃。他想再吃一个,因为他吃的第二个太小了。

例5、A bullet hit the soldier and he was wounded in  ________leg.

A. a     B. one     C. the     D. his

答案为C。

例6、________people in the world are sending information by email every day.

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

答案为A。

[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,世界上有百十万人通过email传递信息。 

例7、________ 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

答案为C。

[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。 

例8、Paper produced every year is ________ the world's production of vehicles.

A. the three times weight of    B. three times the weight of

C. as three times heavy as     D. three times as heavier as

答案为B。

[解析] 表示倍数的词数放在the weight of前,意思是“……重量的几倍”。 

例9、 An accident happened at_________ crossroads a few metres away from_______ bank.

A. a…a    B. /…a    C. /…the    D. the…/

答案为A。

[解析] at a crossroads表示“在十字路口”,crossroads“十字路口”是复数形式单数用法;bank是可数名词,不能单独使用(要加冠词或复数),又非特指,不能用the。此处是泛指,前面要用不定冠词a。

例10、Smith _____ me to buy several _____ eggs for the dinner

A、asked…dozen    B、suggested…dozens of

C、had…dozen     D、persuaded…dozens of

答案为A。

[解析] “dozen +复数名词”前除了用具体数词修饰外,还可以用several, many 修饰,如several dozen people, many dozen students等,dozen 不加s。
