【九年级英语习题答疑】
牛津译林版九年级上册亮点给力提优课时作业本P95
My grandfather served in the army in _____ when he was in ______.
A.1950s;twenties B.1950s;the twenties
C.the 1950s;the twenties D.the 1950s;his twenties
答案:D
句意:我爷爷于20世纪50年代在军队服役,他那时二十多岁。
解析:这道题实际上考的就是两个短语的记忆
1.in one’s twenties:在某人20多岁的时候
这个短语其实很好记,因为是在“某人”20多岁的时候,所以中间要用one’s,然后20多岁,不只有一岁,所以后面的twenty是复数。所以这道题选D。
2.在20世纪50年代:in the 1950s,中间是有定冠词的,并且1950后面要加s。

1.I never expected a man______ could offer such a report with ______ information.
A.in his twenties, a great deal of B. in his twenties, a number of
C. in his twenty, a bit D. in his twenties, a few
答案:A
句意:我从来没有想到一个二十多岁的人能提供这样一份包含大量信息的报告。
解析:第一个空在他20多岁的时候,要用in his twenties,所以C选项是错的。然后第二个空information是不可数名词,B选项的a number of和D选项的a few后面都是加可数名词的,所以B和D都是错的,这道题选A。
2.—My father has worked as a surgeon since he graduated from Beijing Medical University _______.
—So he is______now?
A. in 1990;in his forties B. in 1990s;in his forty
C. in the 1990;in the forties D. in the 1990s;in his fortieth
答案:A
句意:—我父亲自从1990年北京医科大学毕业后就一直做外科医生。
—所以他现在40多了?
解析:首先在我父亲40多岁的时候应该是in his forties,然后C选项写错了,如果是在1990年,应该是in 1990,如果是在20世纪80年代,应该是in the 1990s。
