Question

I can see thars at night,用疑问句和否定句怎么说？

Answer 1

原句应该是：I can see stars at night.

该句的谓语由“情态动词 can + 实义动词 see”构成，所以它的句式变化均要借助于情态动词 can 来进行。不过变成疑问句时，原句中的第一人称要记得改成第二人称。

否定句：I can't see stars at night.

一般疑问句： Can you see stars at night?

Answer 2

回答如下：有误，单词thars 应该改成stars。一般疑问句：Can I / you see stars at night? 特殊疑问句：When can I see stars ? 反意疑问句：I can see stars at night, can't I ? 否定句：I can't / cannot / can not see stars at night.

Answer 3

句子中有情态动词变，一般疑问句时直接把情态动词提到具体开头变否定句时，直接在它后面加not，第一人称一般改为第二人称。
Can you see stars at night？

I can't see stars at night.

Answer 4

I can see that at night. 疑问句 Can I see that at night? 否定句 I can not see that at night.

Answer 5

thars？应该是stars吧。
Can I see stars at night？ (疑问句)
I can’t see stars at night. (否认句)
