（1)Is that your a book? 哪里错了
your 和 a 不能同时使用
改为：
Is that your book?
或：
Is that a book?
（2）This is a pen and that's a ruler?
应为肯定句,因此去掉问号.
（3）Is this his pencil?
此题正确!
再问：不好意思我打错了几个（2）This is a pen and that's a ruler.没有问号,但是有错的（3）Is this his pencil？————Yes,it's
再答：（2）This is a pen and that's a ruler.没有问号,但是有错的修改为：This is a pen and that is a ruler. 此为并列结构，is 最好缩写，或者都缩写（3）Is this his pencil？————Yes,it's 应该为：Yes，it is. is不应缩写。
