Question

一个英语题，请帮帮我~~谢谢啦！！

如果问题是：
Are Nancy and her sister very happy at last?
请问做肯定回答怎样做，做否定回答呢？还麻烦讲一下这个的语法~~谢谢我是英语初学者，希望您能耐心些~~~~

Answer 1

南希和她姐姐最后很开心吗？
肯定：Yes, they are very happy at last.
否定：No, they are not very happy at last.
改成否定句的时候，在be动词后面加not就可以了。

追问

改成否定句的时候,可以直接这样写吗？：
No, they aren't.
不写后面的very happy at last.？

追答

恩，可以的，这样就比较简略了，但是完全正确。

Answer 2

肯定：yes, they are.
否定：no, they aren't.
aren't是are not的缩写。

追问

谢谢~~

Answer 3

yes,they are /no,they aren't
