Question

原因状语从句

Obeying rules will limit children’s imagination because they can’t / couldn't solve problems .
应该用can还是could？原因？

Answer 1

应该用can’t，这是将来时态，不能用couldn't 

常用来引导原因状语从句的从属连词有：because、as、since、for。

除此之外，还有一些其实也较为常见但对于不少基础阶段的英语学习者来说不太熟悉的连接词语，如：now (that)、when、seeing (that) 、considering (that)、given (that)、in that、for the reason that等。

because的用法

because引导的原因状语从句一般放于主句的后面。当because从句位于句首时，要用逗号分开；放在句末时，可不用逗号分开。如：

从句在后（有逗号）：We didn't go for an outing last Saturday, because it was raining hard the whole day.

从句在后（无逗号）：We didn't go for an outing last Saturday because it was raining hard the whole day.

从句在前（必须有逗号）：Because it was raining hard the whole day, we didn't go for an outing last Saturday.

Answer 2

上面主句是将来时态，这里用 can’t,
不可用couldn’t
