题目内容
8.There are stars in the Galaxy.We can't count them.( )| A. | billion of | B. | billions | C. | billions of | D. | billion |
分析 在银河系有数十亿的恒星.我们不能数出它们.
解答 答案:C,考查数词的用法.句意"在银河系有数十亿的恒星.我们不能数出它们."如果billion要加s,只有billions of 这一种用法,没有这种billion of 说法,所以A、B不正确,billions of 是形容数十亿的,billion前面需要加数字,即数字+billion.根据句意There are stars in the Galaxy.在银河系有数十亿的恒星.故选C.
点评 注意量词billion的用法和固定的搭配,再看具体的内容进行判断.
