Question

怎麼把英语句子变成一般疑问句

例：TH IS IS A BOOK

Answer 1

以此句为例：it is a dog. (主系表）；he likes playling basketball.（主谓宾）
变为一般疑问句时，主系表结构的只需将系动词前置，其余照抄即可：is it a dog ?
主谓宾结构的需借助于助动词（do, does ,did等）例句时态为一般现在时第三人称单数，所以选择does；然后把动词likes还原成原型like再照抄下来就可以了。does he like playing basketball?

Answer 2

This is a book.
疑问句：Is this a book？
