英语语法（第一季）Day9:做谓语的实义动词

主谓一致：

谓语动词要随主语人称及数量的变化而产生形式上的变化。

具体规则如下：

以下成分做主语时，谓语动词要用第三人称单数，一般在末尾加s

单数名词
不可数名词
第三人称单数he、she、it
指示代词
动名词

1.不可数名词/单数名词作主语：
1）Ice cream costs money.
2）Apples cost money. ---复数形式，cost用原形
3）An apple still costs money.

2.第三人称单数做主语：
1）I like books.
2）We like books.
3）You like books.
4）He likes books.
5）She likes books.
6）It likes books.
7）They like books. ---这是第三人称复数，like用原形

3.指示代词this，that做主语：
1）This helps people.
2）That helps people.
3）These help people.
4）Those help people.

4.动名词做主语：
1）Reading changes people.
2）I love reading.
3）He loves reading.
动名词做宾语时，对谓语没有任何影响。

谓语是句子中不可缺少的一部分，一个句子至少需要一个谓语，如果出现多个，需要用连词进行连接：

1）She loves him.
2）She hates him.
3）She loves and hates him at the same time.
