I will come up with three approaches that useful to solve this problem.这句话对吗?that那里我不确定

问题描述:

I will come up with three approaches that useful to solve this problem.这句话对吗?
that那里我不确定

兄弟你可以像他们说的不用定语从句,直接去掉that,把useful放在approaches之前
如果就想用定语从句,我认为你应该说that are useful to solve this problem.别忘了be动词

这个好像真不用that,这整句话只有一套主谓,应该不需要连词

这句话语法不对,稍微改就对了:I will come up with three approaches that are useful in solving this problem.但我建议你考虑这个更简洁的说法:I will come up with three approaches for solving this problem....

that is useful to solve.....be useful to 吗
