Ⅳ. Choose the correct answer. 选择正确答案。

A. in B. on C. at
() 2. How much the books?
A. are B. is C. be
() 3. a great trip!

() 4. — is sending us an email?

A. What B. Where C. Who
() 5. My mother and I home tomorrow.
A. will go B. went C. go

1. B；2. A；3. A；4. C；5. A

1. 在具体的日期前要用介词on，June 6是具体日期，所以选B。
2. 主语the books是复数形式，how much询问价格时，be动词用are，所以选A。
3. 这是感叹句，修饰名词短语"a great trip"要用What，符合“What+a+形容词+可数名词单数！”的感叹句结构，所以选A。
4. 根据答语“It's from Emma.”可知是询问发送邮件的人，疑问词用Who，所以选C。
5. tomorrow是一般将来时的标志词，一般将来时的结构为“will+动词原形”，所以选A。
