Icandramcartoons。改否定句？

原句：I can dram cartoons.（我会画漫画。）

改为否定句：I can't dram cartoons.（我不会画漫画。）

英语中陈述句改为否定句怎么改？

1、句中有be动词(am/is/are/was/were)的，在be动词后加not。

如：I can swim.——I can't swim.

He is a math teacher. → He is not a math teacher.

2、句中有情态动词的(can/should/must/would)，在情态动词后面加not;

如：There will be a new building next year. → There will not be a new building next year. (will not可以缩写为won’t)

3、句中没有be动词和情态动词的，在动词前加don’t或doesn’t

① 句中动词为原形的，加don’t .如： I like apples. I don’t like apples.

②句中动词为三单式的，加doesn’t，并将三单式的动词还原成原形。

如：He likes apples. He doesn’t like apples.

4、肯定句中的some在否定句中应改为any

如：There are some students in the classroom. There are not any students in the classroom.

特殊形式的否定句：

(1)肯定句含有every-的合成词时，变否定句时改为no-。

如：Everything is ready.→Nothing is ready.

(2)肯定句中含有always， usually和ever时，变否定句时改为never。

如：He is always late for school.→He is never late for school.

(3)肯定句含有many，much时，变否定句时分别改为few，little。

如：Many students know him.→Few students know him.

(4)肯定句中含有still时，变否定句时应改为no longer。

如：Tom is still in bed.→Tom is no longer in bed.

(5)肯定句含有both， both...and，all时，变否定句时应改为never，neither...nor，none。

如：Both of us are students.→Neither of us is a student.

(6)肯定句含有nearly， almost时，变否定句时应改为 hardly。

如：Lily nearly knows him .→Lily hardly knows him .

(7)肯定句含有“形容词+ enough”时，变为否定句时应改为“too +形容词的反义词”。

如：He is short enough to reachit.He is too tall to reach it.
