问题描述:

Both of the students cannot work out the problem means
A.The two students can not work out this problem
B.Not all the students can work out this problem
C.One student can work out this problem,but the other can’t
D.Neither of the two students can work out this problem
为什么是c

C
这一句是 部分否定
意思是 这两个学生不能全都解决这个问题

Both of the students cannot work out the problem means
"Both of the students cannot" = 两个学生都不能...
C One student can work out this problem, but the other can’t
一个学生可以另一个则不能。 这明显与两个学生都不能 ,并不相同! 是错误的答案!!!
正确答案应该是 D Neither of the two students can work out this problem
"Neither of the two students can" = 两个学生都不能..

选C没错both 和all 在句子中如果和否定词连用,表示部分否定,若要表示全部否定,用 neither 和 none如:Both of us are not teachers.我们两个不都是老师.(不都是...注意:谓语用复数are)Neither of us is teacher....
