老师们您好,我想问一下英语怎么改否定句呢?
改否定句的时候,助动词be动词他们的用法一样吗?怎么改否定句呢?各种情况都要说哦.还有把疑问句改为陈述句怎么改?都是英语

改否定句有两种最基本的情况：
（1）be动词,直接在其后加not
e.g.I am a student.(肯定句) →I am not a student.(否定句)
He is learning English.(肯定句) → He is not learning English (否定句)
(2)句子中没有be动词,而是实意动词,则借助助动词do/ does构成
e.g.She like reading.(肯定句) → She doesn’t like reading.(否定句)
I eat an apple every day.→ I don’t eat an apple every day.(否定句)
注：doesn’t = does not主语为三人称单数时使用 don’ = do not
