1A.
有两种说法都正确:three and a half months或three months and a half.这里只有A符合.
2C.同理于1.
3C
本题想表达厂里五分之三的工人是男的.分数的表达方式是基数词+序数词.其中基数词表达分子,序数词表示分母.当叙述词不是一时,要在序数词后加-s.所以选C.
4D.同理于2.
5B.
这是一种表示方式,在数字,名词之间加上连字符,名词,百,千或月,年等都不变复数,此结构做形容词用.所以应当选B.
6B.
基本同于5.这个结构也可以没有名词.如果要用two months,要用a holiday for two months.所以选B
7A
当百,千,百万,千万等词前面有明确数字时不可以变复数,也不能加of.当hundred后面加of时,表示成百上千的,hundred要变复数.在此题中,应当选A.
8题没有正确答案.如果把B答案改成three fourths就选B.本题问四分之一加二分之一等于多少.显然等于三分之四.
9D
