Question

The boy, with his classmates, often ______ to the library on weekends.

A. go                   B. goes

C. to go                D. are going

Answer

B

【解析】

试题分析：句意:这个男孩，还有他的同学们经常在周末去图书馆。go 去，动词原形；goes 第三人称单数形式；to go 动词不定式；are going 现在进行时。这句话的主语是the boy, with his classmates，谓语动词的形式和with 短语前面的名词形式一致，故这里应该用单数，故选B。

考点：考查主谓一致。
