动名词---
要点：动名词既具有动词的一些特征，又具有名词的句法功能。
动名词的形式，动名词的用法
作主语
Travelingwithfriendsatweekendisfun.
作主语的动名词结构复杂且长时，可用it作形式主语。如：
Itisfuntravelingwithfriendsatweekend.
作宾语Hegaveupwritingfiveyearsago.
作表语Whathehatedmostwasdoingnothing.
动名词作表语时，句子的主语常是无生命名词或what引导的名词性从句。
动名词的复合结构“物主代词（或名词的所有格）+动名词”。如：
Tom’sgoinghomelatemadehismotherangry.
不过，动名词的逻辑主语在遇有以下情况时，必须用名词的普通格（或人称代词的宾格）。
①无生命名词Thegirlswereafraidofthedoorsuddenlyclosing.
作定语There’sadiningroominmyschool.It’sasleepingcar.
②有生命名词，但表泛指。Haveyoueverheardofgirlssmoking?
③两个或以上的有生命的名词并列。
Doyoustillremembermyparentsandmecomingtoseeyouthatday?
