答案是：These are my books 这句话的意思是这些是我的书，改为单数句为 This is my book 它的意思是这是我的书。
上面这道题考察的是单数句和复数句之间的知识点，根据题目的要求，我们要把它变成一个单数据。首先我们找出句复数词对应单数的词。these（这些）单数是this，are单数是is，books单数book。这样连起来就成了单数句。
I have different hobbies, and one of them is reading.
Reading helps me to stay calm. In a fast speed era, it is pivotal for me to find something to slow me down, and reading can perfectly solve that. In addition, reading enlarges my knowledge, so I am more confident when talking to other people.
这个句子的同义句应该就是
My books are here and there.
everywhere意思"到处，处处，每个地方"。here and there的意思也是"这里和那里"，也是"处处，到处"的意思。它们的意思相等。所以直接用后者去替换前者就可以了
同义句就是要找到所给句子中可以被其他单词或者词组替换的部分，然后替换它
My hobby is reading, because there are lots of interesting things in them.
Two years ago, I didn't like reading very much. I had plenty of time, but I spent lots of time on playing with computers.

I've changed now. I enjoy reading novels, because there're lots of interesting stories.
I love to read Harry Potter. That's a good novel. I know that it is one of the best-sellers in England.
I'm always lose myself in the interesting stories
我的书在哪里 where是（疑问副词）在哪里 are是“是”的意思 my是我的 books是复数“书”的意思
My hobby is reading books.意思是:我的爱好是看书。它的同义句有四个，1.Reading books is my hobby.看书是我的爱好。
2.I'm interested in reading books.我对看书感兴趣。
3. I like reading books.我喜欢看书。
4.I'm interested to read books.我对看书感兴趣。
这个句子是一般现在时的陈述句句型。中文意思:我的书在书架上。英语中对划线部分提问也就是把这个句子变为特殊疑问句。我们现在对地点状语in the bookcase进行提问。对地点提问要用疑问词Where.特殊疑问句构成是:疑问词+be/情态动词+/助动词+主语+其他。此句特殊疑问句为:Where are your books

该句是英语中较常用的There be句型，表示某处有某物。因此此类句型翻译为中文则为……地方有……。在英文中含有be动词is，am，are时变一般疑问句时则只需要将be动词提前即可。所以此句变一般疑问句：Are there your books?但是要注意原句中形容词性物主代词是my变为问句是需要变成your。
肯定回答：Yes,there are.否定回答：No，there aren't.还需要注意的是若陈述句有some,some要变any.
