5、. 在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。 但有些同学们对于哪些主语是第三人称单数还不十分清楚。现归纳总结如下：一、人称代词he, she, it是第三人称单数。 如： he likes watching tv. 他喜欢看电视。 she has lunch at twelve. 她十二点吃午餐。 二、单个人名、地名或称呼作主语；是第三人称单数。 如：han mei likes salsd . 韩梅喜欢萨拉。 beijing is in china. 北京在中国。 uncle wang often plays volleyball.

6、 王叔叔经常打排球。 三、单数可数名词或“this / that / the+单数可数名词”作 主语时，是第三人称单数。 如：this book is yours. 这本书是你的。 that car is red. the cat is lucys. 这只猫是露茜的。 四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，是第三人称单数。如：everyone is here. 大家到齐了。 this is a pen. 这是一支钢笔。 五、不可数名词作主语时为第三人称单数。如：the milk（牛奶

8、watch-watches wish-wishes do-does go-goes （3）以“辅音字母加- y”结尾的动词，要先变y为i再加-es try-tries study-studies cry-cries fly-flies 不规则变化：be- is have-has 三、一般现在时的句子转换：（1）变一般疑问句：当句子中有be动词或情态动词时，则把be动 词或情态动词(can,could等)提到主语的前面，（口诀：一调二变三问号）（2）变否定句变否定句：在be动词或情态动词后面直接加not变成否定句 (be）后not莫忘记) 例：陈述句：she is my sister. 否定句
