Mr.Johnson,together with his wife and two daughter,______ ,to arrive on the evening flight.

问题描述:

Mr.Johnson,together with his wife and two daughter,______ ,to arrive on the evening flight.
A are going
B are
C will
D is
这里我选择的是A...很无奈的不懂为什么会是错的..

together with his wife and two daughter 做伴随状语 不是句子真正的主语.这个句子的主语是Mr.Johnson 所以谓语动词用单数形式.
建议你看看英语语法的主谓一致 那块,具体的又详细解释的.
