指代问题,第二句话为什么开头用this ?感觉这样指代不清啊.
Personally,I think that students' understanding of morality determines their success. This not only improves their behavior at school,but also prevents some behavioral problems.
这里的this应该是指的学生对道德的认识,但是这个句子这么写的话不也有可能去指代 他们的成功 这个吗?求解!
还有一个问题,第二句话可以加助动词can吗?就是说可以这么写吗?
This can not only improves their behavior at school,but also can prevents some behavioral problems.

Answer 1

先回答第二个问题
can后面的动词是原形
This can not only improve their behavior at school, but XXXX
这样写是可以的
第一个问题
this用在这里比较混淆概念,既可以指代认知,又可以指代成功,还可以指代“认知决定成功”这件事
