如题，英语的介系词有一说后面不能接句子，严格规定后面只能接名词或动名词(包括名
词词组)
但也有人说后面可以接名词、动名词(包括名词词组)跟句子
就有例如：I look forward to which ice cream Mary will eat. 介系词to
后面接了一个名词子句“which ice cream Mary will eat”
以上 小弟感到很困惑英语的介系词后面到底可不可以接句子？
感谢大家

从来没有听过这个规则，来自 The Economist 的句子：Japan must and can act decisively torevive its economy. It has every reason in itsown interests to do so, but the fate of theregion also hinges on whether it meets thechallenge. to hinge on (介系词) 接 whether-clause

谢谢您
