Doing非doing，用法不一样Doing是非谓语动词中的一种，但是在英语中由于用法不同有两个说法，一个是动名词，另一个是现在分词，该语法即是学习难点，又是高考重要考点，而学生还容易混淆，为此笔者做了一些总结，希望有助于“doing”一词用法的学习一、动名词动名词的形式及特性：动名词的形式是由动词原形+ing 构成，动名词有时态和语态的变化，兼有动词和名词的特征，因而在句中可以作主语、表语、定语、动词的宾语、介词的宾语等。
1.doing的一般式是doing，表示动作与谓语动词同时发生或在其后发生，或表示一般情况。
Eg. Learning is important to modern lifeIt’s a wonder meeting you hereI am thinking of getting a new dictionary2. doing的完成式为having done，动名词的完成式所表示的动作在谓语动词动作之前发生，he didn’t mention having failed the exam.He denied having done anything illegal.但是要注意有些明确表示时间的动词和介词after/on/upon/for之后，常用一般式代替完成式，表示动作发生在谓语动作之前。
After having （had）some practice，he decided to try again.After hearing（=having heard）that good news，she couldn’t help laughing3. doing 的被动语态为being done：当动名词的逻辑主语是行为的承受者时，用被动语态eg. This question is far from being settledshe is proud of being admitted into the university.Being lost in the forest is a terrible thing4. 特殊情况必须用动名词：1）动名词做宾语：有些动词或短语动词后常用动名词作宾语。
