Question

我要写一个句子,其中用到一个定语从句：是由（&&&&）引起的/导致的.
注意：（&&&&）是个句子
我想写成：which was caused by that （&&&&)
或者写成：which result from that （&&&&)
但我不知道by或者from后面是否可以接句子,我关键是想接个句子
或者不用cause和result,不知还有没有更合适的表达由什么引起,又能接句子的词

Answer 1

which was caused by that 和which result from that 后面是不能接句子,只能接名词短语,如果非要用定语从句,那么后面接短语就好,还显得简洁.
比如：
The population of China has been largely controlled,which is result from the policy of Family Planning.(计划生育政策)
我再说几个可以表达原因的表达：
1 The reason why .is that（后接句子）
2 Provided that.,主句...= since that.,主句...
3 Thanks to /Due to.,(这里只能是名词短语),主句.
一点提示
