牛津譯林版九年級上冊亮點(diǎn)給力提優(yōu)課時作業(yè)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:我爺爺于20世紀(jì)50年代在軍隊(duì)服役,他那時二十多歲。
解析:這道題實(shí)際上考的就是兩個短語的記憶
1.in one’s twenties:在某人20多歲的時候
這個短語其實(shí)很好記,因?yàn)槭窃凇澳橙恕?0多歲的時候,所以中間要用one’s,然后20多歲,不只有一歲,所以后面的twenty是復(fù)數(shù)。所以這道題選D。
2.在20世紀(jì)50年代:in the 1950s,中間是有定冠詞的,并且1950后面要加s。
[鞏固練習(xí)]
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:我從來沒有想到一個二十多歲的人能提供這樣一份包含大量信息的報告。
解析:第一個空在他20多歲的時候,要用in his twenties,所以C選項(xiàng)是錯的。然后第二個空information是不可數(shù)名詞,B選項(xiàng)的a number of和D選項(xiàng)的a few后面都是加可數(shù)名詞的,所以B和D都是錯的,這道題選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:—我父親自從1990年北京醫(yī)科大學(xué)畢業(yè)后就一直做外科醫(yī)生。
—所以他現(xiàn)在40多了?
解析:首先在我父親40多歲的時候應(yīng)該是in his forties,然后C選項(xiàng)寫錯了,如果是在1990年,應(yīng)該是in 1990,如果是在20世紀(jì)80年代,應(yīng)該是in the 1990s。
