问题描述:

Since the spiders eat the insects ,the farmers save a lot of money on pesticides改为同义句
______ _______ the spiders eat the insects,the farmers save a lot of money on pesticides!
要求填两个!

这个句子中的since应该翻译成因为、由于的意思.而且后面引导的是句子,并且要求两个词,我只能想到in that这个引导词.用now that其实也可以,但是这个词组大多数是当“既然”来用的,所以我觉得还是in that比较合适.
