题型：不详难度：来源：
Sixteen-year-olds to drive.| A．is allowed | B．are not allowed | | C．allowed | D．is not allowed |
|
答案
| B |
解析
试题分析：句意：不许十六岁的孩子们驾车。结合语境可知本句主语为被允许的对象，故用被动语态。主语Sixteen-year-olds为复数形式，故选B。
点评：此类题型主要是确定句子主语与谓语动词的关系。如果是主动关系则用主动语态，反之如果是动宾关系，则用被动语态。be动词往往根据句子的主语而有所不同，其应用原则可以结合如下歌谣来记忆；我用am，你用are；is用在他、她、它。单数名词用is，复数名词全用are。 |
