知道三种英语否定句的表达，用英语说不就没问题了，哪三种啊？
第一部分
1] 以助词＋not 构成的否定句，翻译为“不”。
否定句:
[1]有am is are was were can may must need will shall have has had的句子变成否定句, 在后面加not
[2]如果没有，在动词前面加do not/does not/did not 变成否定句
I am a new cook →I am not a cook.
I can make bread →I can not make bread.
I work as a cook →没有第一点提到的词
I do not work as a cook.
He does not work as a cook,either.
Bake【is not】able to do that
