Methane, which has long been counted among the greenhouse gases that are implicated in global warming, comes both from natural sources such as bogs and from a host of human sources, including coal mines, leaking pipelines, landfills, and rice paddies.





(A) that are implicated in global warming, comes both from





(B) that are implicated in global warming, coming from both





(C) being implicated in global warming, comes from both





(D) implicated in global warming and coming both from

(E) implicated in global warming, that come both from

这个句子里面...为什么A不把that are省略呢...我觉得省了应该更好...

可能觉得去掉了会觉得implicated当成谓语了吧

charles1992

the greenhouse gases that are implicated

后置定语implicated本来就相当于一个定语从句（that are implicated ） 所以that are implicated 和impilicated是一样的不存在谁更简洁~

个人理解 请各位NN继续指教~

umm...谢谢楼上两位，但似乎还是不是很清晰...顶顶，看看有没有其他看法

个人觉得去掉了也不是不可以，但是后面必须是comes from,而加being又是必错的，所以也就只能是A了吧。。。

jasonlover

that are 省略最好只适用于后面是形容词的情况.

我想问一下D项中implicated和coming能不能一起并列用来修饰“greenhouse gases”呢？？
我记得定语从句要慎重使用啊 有时THAT+BE 形式会被视为不简洁啊  请各位指教
