Learning English takes patience. 2. 常见句型 句型 示例 说明 直接作主语 Eating vegetables is healthy. 谓语用单数 It作形式主语 It is no use crying over spilt milk. 避免"头重脚轻" 注意： 动名词作主语时，谓语动词必须用单数 Playing sports are healthy. Playing sports is healthy. 否定形式：not + 动名词 Not smoking is good for your health. 三、动名词作宾语 1. 必须接动名词作宾语的动词 动词 例句 固定搭配 enjoy I enjoy singing. enjoy doing finish She finished reading. finish doing practice They practice speaking. practice doing mind Do you mind opening the window mind doing avoid He avoided answering. avoid doing 2. 接动名词的短语 短语 例句 结构 be good at She is good at drawing. be good at doing look forward to I look forward to seeing you. look forward to doing feel like Do you feel like eating feel like doing can't help I can't help laughing. can't help doing 3. 介词后必须用动名词 She is interested in dancing. Thank you for helping me. 四、动名词的特殊用法 动名词的复合结构 物主代词/名词所有格 + 动名词 Do you mind my smoking here I appreciate Tom's helping me. 动名词的时态和语态 形式 主动语态 被动语态 一般式 doing being done 完成式 having done having been done 例句： He admitted having made a mistake. She disliked being treated like a child. 五、易错点辨析 动名词与现在分词的区别 动名词：具有名词性质（作主语/宾语） Swimming is fun.（主语） 现在分词：具有形容词或副词性质（作定语/状语） The swimming pool is large.（定语） 只能接动名词的常见动词 admit, advise, consider, delay, deny, escape, imagine, miss, postpone, risk, suggest等 既可接动名词又可接不定式但意义不同的动词 动词 动名词 不定式 remember 记得做过某事 记得要做某事 forget 忘记做过某事 忘记要做某事 try 尝试做某事 努力做某事 mean 意味着 打算 例句对比： I remember seeing him.（记得见过） Remember to see him.（记得要去见） 六 、记忆口诀 "动名词，-ing形，主宾用法要记清； 作主语，谓单数，It替代可变形； 作宾语，记动词，enjoy/mind加doing； 介词后，必-ing，固定搭配记分明！" 1．Thank you_____ me.
