Answer 3

第一个句子的意思说，这是他的铅笔,一个一般现在时态的句子,主要句子构成是主语加be动词加其他，因为有了be动词，所以他想要变成否定句，直接在be动词的后面加not,所以它的否定形式为:
It is not his pencil.
第二个句子的意思，那是他的桌子,也是主语加be动词加其他的构成,改变成一般疑问句，只需要将be动词提前,主语换位置,首字母大写将句号变为问号就可以,最终的答案是:
Is that his desk?

Answer 4

It isn't his pencil .

Is that a desk?
Yes， it is.
或
No，it isn't.

句子中有be动词，变否定句是直接在be后加not
变一般疑问句是直接把be提到句子开头
