题目内容
8.Nearly _________ of the earth ________covered by sea.( )| A. | three fourth; is | B. | three fourths; is | ||
| C. | three fourth; are | D. | three fourths; are |
分析 几乎地球表面的四分之三被海洋覆盖.
解答 答案:B.
根据选项可知,第一个空所缺为分数;又知分数的表达法为分子基数词,分母序数词,分子大于一,分母加s,所以四分之三的表达方法为three fourths.又根据分数作主语时,其后的谓语动词的单复数取决于它所修饰的名词,即此处的earth,这里是单数形式,所以第二个空缺处应用is.故选B.
点评 本题考查分数的用法,分数的表达形式为:基数词(分子)+序数词(分母),分子大于一时分母加s.
