一、找出每组中画线部分发音与其他不同的单词。

C. brother
() 3. A. must
B. rule
C. rubbish
() 4. A. telephone

() 5. A. safe
B. traffic

1.C 2.C 3.B 4.C 5.B

1. A.light/l/，B.little/l/，C.side/s/，C发音不同。
2. A.follow/ɒ/，B.cross/ɒ/，C.brother/ʌ/，C发音不同。
3. A.must/ʌ/，B.rule/uː/，C.rubbish/ʌ/，B发音不同。
4. A.telephone/e/，B.left/e/，C.diet/aɪ/，C发音不同。
5. A.safe/eɪ/，B.traffic/æ/，C.cake/eɪ/，B发音不同。

二、用所给词的适当形式填空。
1. How (cross) the road (safe)?
2. You mustn't (cross) the road now. You must look for a zebra (cross).
3. She can see many traffic (light) on the road.
4. He must (finish) his homework before dinner.
5. Must Nancy (wash) clothes now?
6. I can draw this picture (easy).
7. You shouldn't (talk) loudly in the classroom.
8. Wang Bing didn't (play) football on the road.
9. We're late. Let's run (quick).
10. Look, the bus (stop) on the road.

1. to cross; safely
2. cross; crossing
3. lights
4. finish
5. wash
6. easily
7. talk
8. play
9. quickly
10. is stopping

1. "How" 后通常接动词不定式，构成 "How to do sth." 的结构，表示“如何做某事”。“safe” 的副词形式是“safely”，用来修饰动词“cross”。所以填“to cross; safely”。
2. “mustn't”是情态动词，后面接动词原形。“cross”的名词形式“crossing”表示“十字路口”，在这里作为“look for”的宾语。所以本题答案是“cross; crossing”。
3. “many”后接可数名词复数形式，“light”的复数形式是“lights”。
4. “must”是情态动词，后面接动词原形，所以用“finish”。
5. “must”是情态动词，一般疑问句中将“must”提前，后面接动词原形，所以用“wash”。
6. 这里需要用副词修饰动词“draw”，“easy”的副词形式是“easily”。
7. “shouldn't”是情态动词，后面接动词原形，所以是“talk”。
8. 否定句中，借助助动词“didn't”，后面动词用原形，所以是“play”。
9. 这里需要用副词修饰动词“run”，“quick”的副词形式是“quickly”。
10. “Look”表明是现在进行时，其结构是“be + 动词现在分词”，“the bus”是单数，be动词用“is”，“stop”的现在分词是“stopping”。

三、根据中文意思将句子补充完整，每空一词。
1. 你可以在人行道上等，和其他人一起过马路。
You can wait on the and cross the road other people.

4. children; are; crossing; road; stop; wait
5. first; left; carefully
6. Follow; stay; safe

3. 特殊疑问句"什么"用"What"，"必须做"是"must do"，"为了安全"用"safely"。
