四、根据要求改写句子,每空一词。
1. Danny should go out to play. (改为否定句)
Danny out to play.
2. Are you sad? (作否定回答)
, I .
3. I will go swimming this afternoon. (对画线部分提问)
swimming?
4. Li Ming will buy a T-shirt for his father. (对画线部分提问)
Li Ming for his father?

1. shouldn't; go
2. No; am; not
3. When; will; you; go
4. What; will; buy

1. 原句含有情态动词should，变为否定句时，直接在should后加not，可缩写为shouldn't，后面接动词原形go，符合情态动词否定结构"shouldn't+动词原形"的规则。
2. 一般疑问句"Are you sad?"的否定回答遵循对应规则，开头用No，主语转换为I后对应的be动词是am，否定形式为am not。
3. 画线部分this afternoon是时间，对时间提问要用特殊疑问词When，原句为一般将来时，需要把助动词will提前，同时第一人称I转换为第二人称you，后面接动词原形go，即可构成完整问句。
4. 画线部分a T-shirt是物品，对物品提问要用特殊疑问词What，原句为一般将来时，将助动词will提前，后面接实义动词原形buy即可。

五、读短文，判断正(T)误(F)。
A crow is sitting and singing under the tree. She does nothing all day. A small rabbit sees the crow, and asks her,“Can I also sit like you and do nothing all day long?” the crow answers, “Sure ,why not?”
So the rabbit sits on the ground beside the crow, and sings with her.
All of a sudden, a fox appears(出现), jumps on the rabbit and eats it.
() 1. The crow is eating under the tree.
() 2. The crow is busy all day.
() 3. The rabbit wants to sit and sing like the crow.
() 4. The tiger eats the rabbit.
() 5. The rabbit is very hard-working(勤奋的).

1. F 2. F 3. T 4. F 5. F
