Seeingisbelieving.一.動名詞做主語的用法動名詞做主語往往表示經(jīng)常性、習(xí)慣性的動作Helpingherismyduty.眼見為實.（指抽象動作,泛指）（指具體的一次動作）不定式做主語往往表示具體的動作，特別是將來的未完成動作。如：Spittingeverywhereisnotpolite.Tospitherewillbepunished隨地吐痰是不禮貌的在這里吐痰要受懲罰。【考例】—WhatdoyouthinkmadeMarysoupset？—__________hernewbicycle．（1997上海高考題）A.Asshelost

B.LostC.Losing

D.Becauseoflosing解析：losinghernewbicycle是句子的主語，謂語madehersoupset被省略，losing…在此表示已經(jīng)發(fā)生具體的動作。

1．有些動詞或短語動詞后常用動名詞作賓語。如admit（承認）,avoid（避免）,consider（考慮）,devote…to,enjoy，escape,feellike,finish,forgive,suggest,imagine（想像），mind,practice，miss（錯過）delay(延誤)appreciate(感激，欣賞).
