they代指。

【一般疑问句句型结构】 Be动词(Is/Are) + 代词 + 名词
重点句型一
【肯定回答】 Yes,主语 + be动词(is/are).
【否定回答】 No,主语 + be动词(is/are) + not.
Are these pencils
Yes, they are./No, they aren't.
这些是铅笔吗
是的。/不,不是。
含有实义动词的一般疑问句要借助于助动词do和does来构成,将其放到句首,其他词顺序不变。肯定回答用“Yes,主语 + do/does.”,否定回答用“No,主语 + don't/doesn't.”。
【例句】 — Do you like apples 你喜欢苹果吗
— Yes, I do./No, I don't.是的,我喜欢。/不,我不喜欢。。
拓展
2.询问“这些是什么？”的句型：What are these
这是由what引导的特殊疑问句。主语的单复数形式
决定be动词用is还是are。these是代词，用来指代
复数名词，因此be动词用are。这个句 型回答为：
They’re…
例句： —What are these
—They’re eggs.
