You should see to it that all the lights must be turned off before you leave.你应该负责离开时所有的灯都关掉.介词后面可以加动词ING形式或者主语变为其所有格形式 主语是物的话，主语不变， 谓语变动名词 例如I was aware of there being a good job! 追问： I agree with that you want to go!这句话对吗？ 回答： 介词后能不能直接用THAT 比如I agree with you that David is a clever guy,but I think he was very foolish just now ...
