It seems likely that a number of astronomical phenomena, such as the formation of planetary nebulas, may be caused by the interaction where two stars orbit each other at close range.
(c) are because of the interaction between two stars that orbit each other
Choice C can be faulted because to form a passive construction, are should take a verb form such as caused rather than an adverb such as because.
这句解释该如何理解,我觉得be+because of 的结构没有不对呀,请nn指点because of 在句中的位置及相关用法,谢谢
“现象是因为”?不顺吧,如果非用because of,也应该是“现象的产生是因为”吧?
我觉得OG这里是已经把该句子判断成用被动语态,所以才有are should take a verb form such as caused rather than an adverb such as because,
如果不是被动语态的话,这条规则就不是规则了。呵呵
是否可以这样理解:because of 通常不做表语。那么,它在句中的位置一般在哪?非常感谢大家的热心解答。
怎么没人回答呀,because of 在句中的位置有规定吗,是否不能做表语,谢谢!
