Jack isn’t ___________ the best student in our class.

问题描述:

Jack isn’t ___________ the best student in our class.
A.suppose to B.supposed C.supposed to D.supposed to be
我要原因,

D,jack 不是我们班上最好的学生,supposed to 是假设,被认为,若是直接supposed to,后面要加动词原型,所以是bebe supposed to do sth. 不是应该做某事 吗后面是动词,但是 the best student,前面应该是系动词,而不应该是及物动词
