Question

Both the teacher and the students________able to give the answer to the problem．In fact．the problem is not difficult．
A.is
B.aye
C.isn't
D.aren't

Answer 1

答案B
分析：主语是both the teacher and the students,不管是both…and…,还是both,还是both of…总是看成复数.另外,从In fact,the problem is not difficult．可以看出应该是肯定概念.(延伸)含有both的句子如果谓语出现否定结构的话,其意义是部分否定,如：Both the teacher and the students aren't able to give the answer to the problem．应该解释为“并不是老师和学生都能给出这问题的答案.”(不能理解为“都不能够”)
