解析：把英语句子改为否定句，一般来说只要加上否定词not就可以了。

英语否定句是表示否定的句子，必须有否定词。有了否定词才算否定句。英语否定句是中国人学习英语的一个重点，也是一个难点。唯有突破这类难点，才能使我们的英语学习有质的飞跃。下面一起来学习相关知识：

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.

Answer 2

句子是主系表结构，
主语：he，系动词是：is ，表语是:late。
对于这个结构的句子，只需要在系动词后面加not就好。
所以否定形式为： he is not late today.简写为：
He isn't late today.

Answer 3

He is not late today.
