This is the method ( ) he solved the problem.

括号处要用什么关系边词？？

先解释文法错 不可以 this is .... he solved
对的是 this is ... he solves 或 this was ... he solved
This is the method (with which) he solves the problem.
This is the method (by which) he solves the problem.
This is the method (using which) he solves the problem.

method with
way of doing
way to do
approach to do
都是做什么的方法

谁能解释一下原因啊

which

that/which
