中考作文句型练习（动名词做主语）

1. 定义：动名词是具有名词性质的动词形式，是一种非谓语动词。
2. 用法：常表示抽象的、经常性和习惯性的动作。
Seeing is believing. 眼见为实。
3.主谓一致：单个动名词（短语）作主语时，谓语动词用单数形式；两个或两个以上表达不同意义的动名词（短语）作主语时，谓语动词用复数形式。
Talking is easier than doing . 说比做容易。
Watching TVand reads books become a routine for me since then.
从那时起，看电视和读书就成了我的日常生活。
4.形式主语it：为使句子平衡，用 it 作形式主语，把动名词（短语）置于句末。
【常见句型】：

(2) It is/was a waste of time/money doing sth. 做某事是浪费时间/金钱。

5. 动词-ing形式的变化规则：
(1) 一般情况下，直接加-ing;
go—going ask —asking look—looking carry—carrying
(2)以不发音的-e结尾的动词，去-e加-ing;
write—writing make—making take—taking move—moving

【特别注意不定式、动名词作主语时的区别】：
1.一般来说，表示比较抽象的、经常的行为,通常不与特定的动作执行者联系在一起，多用动名词;
Swimming is my favourite sport and I swim three times a week. (一般性动作）
2.而表示特定的，具体的行为，特别是将来的行为,强调的是动作,往往与特定的动作执行者联系在一起，多用不定式。
