一、根据句意，选词填空。(可重复使用)
1. It's 6:30. It's time get up.
2. It's 9:20. It's time Chinese class.
3. It's 5:30. It's time dinner.
4. It's 10:40. It's time have an English class.
|A. for|B. to|
|----|----|

1. B
2. A
3. A
4. B

本题主要考查“It's time for sth”和“It's time to do sth”的用法区别。“It's time for”后面接名词，表示“到做某事的时间了”；“It's time to”后面接动词原形，也表示“到做某事的时间了”。
1. “get up”是动词短语，所以用“to”，即“It's time to get up.”
2. “Chinese class”是名词短语，所以用“for”，即“It's time for Chinese class.”
3. “dinner”是名词，所以用“for”，即“It's time for dinner.”
4. “have an English class”是动词短语，所以用“to”，即“It's time to have an English class.”

二、单项选择。
() 1.It's 7:30. It's time for .
A. go to school
B. breakfast
C. lunch

B

根据四年级下册所学，"It's time for + 名词"表示“到了做某事的时间”。7:30通常是上学或吃早餐的时间，选项A是动词短语，不能直接跟在for后；选项C“lunch”（午餐）时间通常较晚，7:30不符合。所以选B。

() 2.—It's time for maths class. —

A.I'm ready.
B.I'm sorry.
C.I'm OK.

A

题目情境为“到数学课时间了”，A选项“I'm ready.”表示“我准备好了”，符合上课前的回应；B选项“I'm sorry.”用于道歉，C选项“I'm OK.”表示“我没事”，均与情境不符。

() 3.Hurry up. It's time for .

A.to go to school
B.have lunch
C.school

C

本题可根据“It's time for sth.”这一固定句型，其后应接名词，来分析各个选项。选项A“to go to school”是动词不定式，不符合该句型用法；选项B“have lunch”是动词短语，也不符合；选项C“school”是名词，符合“It's time for sth.”的用法。

() 4.—What time is it? —

A.It's 8:20.
B.It's time to get up.
C.It's time for dinner.

A

题目询问的是具体的时间点，问“现在几点了？”，需要回答具体的时间。选项A给出了具体时间“8:20”，符合题意；选项B和C分别表示“该起床了”和“该吃晚餐了”，是对于时间的回应而非具体时间点，不符合题目要求。

三、选择合适的句子补全对话。
Mike: 1.
Mum: It's 7:30.
Mike: 2.
Mum: Yes. 3. Don't be late.
Mike: OK. But where is my bag?
Mum: 4.
Mike: Oh! Thank you. Goodbye.
Mum: Bye, Mike.
|A. Please hurry up!|
|B. What time is it, Mum?|
|C. It's time to go to school.|
|D. It's on the desk.|
|----|----|----|----|

1. B
2. C
3. A
4. D
