7.-Is it _________ eraser?-No,it isn't.It's ________ toy.( )
| A. | an,an | B. | an,a | C. | a,an |
分析 --它是块橡皮吗?
--不,它不是.它是个玩具.
解答 答案:B 本题主要考查不定冠词a (an)与数词one 同源,是"一个"的意思.a用于辅音音素前,而an则用于元音音素前,the用于上文提到过的人或事,又一次提到,或者特指时.第一个空是泛指,eraser首字母是元音音素,所以要用an,第二个空是泛指,且toy首字母是辅音音素,故要用a,所以选择B.
点评 本题主要考查不定冠词a (an)与数词one 同源,是"一个"的意思.a用于辅音音素前,而an则用于元音音素前,the用于上文提到过的人或事,又一次提到,或者特指时.
