Question

10._______ has been done.
A.ninety—nine percents of the work \x05
\x05B.Half of what he promised
\x05C.Two-fifths of the articles \x05
\x05D.Three quarter of the business
选哪个,

Answer 1

选C
A选项 考的是百分数的使用方法.要注意无论是百分之多少,都不可用percent的复数,若选该选项,应为Ninety-nine percent of the work,另外注意work表工作时不可数,works表工厂或物品.
B选项 考的是分数的使用方法.若是1/3或1/5应为one third ,one fifth,2/5则为two fifths,但后面的artcles与谓语动词has不符,应为Two-fifths of the work
C选项 是一个主语从句,要注意half的谓语动词应用单数
D选项 quarter可数,正确的应为Three quarters of the business
