一般现在时中的第三人称单数形式
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。
(一)什么是一般现在时?

3.表示客观现实。
如:

(二)哪些主语是第三人称单数?

②BeijingisinChina.北京在中国。
③UncleWangoftenmakescakes.王叔叔经常做蛋糕。
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。

②"I"isaletter."I"是个字母。
除上述规律外,还应注意下面三点:
1.动词have,遇到主语是第三人称单数时,要用has;动词be的第三人称单数形式是is。
2.含有动词第三人称单数形式的句子变否定句时,要用doesn't+动词原形,如:
Hegoestoschoolatsixinthemorning.(变否定句)→Hedoesn'tgotoschoolatsixinthemorning.
3.对含有动词第三人称单数形式的句子提问时,要用助动词does,如:
Shegoeshomeatfiveeveryday.(对划线部分提问)→When/Whattimedoesshegohomeeveryday?
(三)含有动词第三人称单数形式的句子变否定句和疑问时怎样变?
【注意:
】只要句子中出现do,does,don’t,doesn’t,句子中原来的实意动词要用原形
例如:
Helikesapples.(改成否定句)
Hedoesn’tlikesapples。
(错)
Hedoesn’tlikeapples。
(对)
A否定句:
(1)当主语是第一,二或复数时,主语+don't+动词原形(+其它)。
如:
Idon'tlikebread.
(2)当主语为第三人称单数时,要用doesn't构成否定句。
如:
Hedoesn'toftenplay.
B一般疑问句:
(1)当主语是第一,二或复数时,Do+主语+动词原形+其它。
如:
Doyouoftenplayfootball?
-Yes,Ido./No,Idon't.
(2)当主语为第三人称单数时,要用does构成一般疑问句。
如:
.be动词包括:
am,is,are。
第三人称单数用is;过去式为was;复数用are,过去式为were.
.动词have,遇到主语是第三人称单数时,要用has;动词be的第三人称单数形式is。
