英文關於「cannot」的問題

當用he/she/it時用cannot，後面個verb不用加s？
Cannot = ability to doing something
e.g.
He cannot go to school because he is sick.
She cannot do the homework because her arms are hurt.
The bird cannot fly because its legs are hurt.
John cannot be so careless.

樓上位仁兄，
Ｈｅ　ｃａｎｎｏｔ　ｇｏ　ｔｏ　ｓｃｈｏｏｌ　ｂｅｃａｕｓｅ　ｈｅ　ｉｓ　ｓｉｃｋ
同
Ｈｅ　ｃａｎｎｏｔ　ｇｏ　ｔｏ　ｓｃｈｏｏｌ　ｂｅｃａｕｓｅ　ｈｅ　ｇｅｔ　ｓｉｃｋ
都無分別，get sick 同 is sick 係一樣架！我只想提醒你。

你好，是的，我们通常都是用回原本的动词在 cannot 的后面，无论什么代名词 (pronoun) 或人的名字也好，也就是说用不带 to 不定式 (bare infinitive) 的动词 (verb)，动词后面没有加任何东西，譬如 s、-ing、-ed 之类的形式。

你可以参考以下的网址，里面有我的解释。。。

我想说 He cannot go to school because he is / gets sick. 语法上都是正确的。

我们也可以写成 He cannot go to school because he feels sick. 的。

由于 To get + adjective = to become, show a change of state，所以我们可以写 get cool、get hungry、get tired、get married etc. 的咯。

希望能帮到你咯。。。: )

所有modal verb都吾洗
(modal verb系can,must,would,could,might,will等等)

總之系not就吾洗,,無論系he/she/it

**勿c0py !**

The verb after modal verbs (e.g. can, may, will) should be the original word that you get from the dictionary, i.e. dont add s, ed, ing or anything to it.

By the way,
Ｈｅ　ｃａｎｎｏｔ　ｇｏ　ｔｏ　ｓｃｈｏｏｌ　ｂｅｃａｕｓｅ　ｈｅ　ｉｓ　ｓｉｃｋ是正確

Ｈｅ　ｃａｎｎｏｔ　ｇｏ　ｔｏ　ｓｃｈｏｏｌ　ｂｅｃａｕｓｅ　ｈｅ　ｇｅｔ　ｓｉｃｋ是錯的

get + past participle is informal English.
get + adjective is wrong.

cannot後面個verb不需要加s
還有一些字後面個verb都不需要加s, 例如:
will, will not
should, should not
do not, did not
must, must not
may, may not
shall
to

he/she/it時用cannot，後面個verb不用加s

第三人稱單數, 就要加S

不需要，而且不止是ｃａｎｎｏｔ，而且ｗｉｌｌ，ｓｈａｌｌ等等都不需要加ｓ
舉個例：
Ｈｅ　ｃａｎｎｏｔ　ｇｏ　ｔｏ　ｓｃｈｏｏｌ　ｂｅｃａｕｓｅ　ｈｅ　ｉｓ　ｓｉｃｋ
他不能上學是因為他生病了

更正．．．．

Ｈｅ　ｃａｎｎｏｔ　ｇｏ　ｔｏ　ｓｃｈｏｏｌ　ｂｅｃａｕｓｅ　ｈｅ　ｉｓ　ｓｉｃｋ是錯的，正確應該是：

Ｈｅ　ｃａｎｎｏｔ　ｇｏ　ｔｏ　ｓｃｈｏｏｌ　ｂｅｃａｕｓｅ　ｈｅ　ｇｅｔ　ｓｉｃｋ

（ｔｏ後面不用轉任何文法）

當用he/she/it時用cannot
後面個verb五洗
