题目内容
Over 20% of the students at that school _____ the habit of smoking, which is beyond imagination.
| A．is | B．are | C．has | D．have |
D
解析试题分析：考察主谓一致。本题的主语是20% of the students，属于分数，百分数。分数，百分数做句子主语的时候，后面的谓语动词的单复数形式要看分数百分数后面的名词，如果后面的名词是可数名词复数形式，那么谓语动词就使用复数形式。如果后面的名词是不可数名词或者可数名词单数，那么谓语动词就使用单数形式。本题20% 后面是可数名词复数形式students，故使用复数形式。句意：那所学校里超过百分之20的学生有抽烟的习惯，这是难以想象的。根据句意说明使用have，表示有…的习惯。故D正确。
