一、用括号内所给词的正确形式填空。
1. —David, where is Amy now?
—She with her twin sister (prepare) for the talk show tomorrow.
2. —What a nice day! Let's go out to play.
—Wait a minute. I (wash) the car for my mother.
3. —Listen! Who (play) the piano in the music room?

5. — your sister (make) a birthday cake now?
—Yes, she is.
6. —Where is your brother, David? I can't find him.
—Maybe he (take) a walk with his friends in the park now.

1. is preparing 2. am washing 3. is playing 4. am cleaning 5. Is; making 6. is taking

1. 主语She后接with her twin sister，谓语动词与She保持一致，now提示用现在进行时，填is preparing。
2. 由“Wait a minute”可知动作正在进行，填am washing。
3. “Listen!”提示动作正在发生，who作主语视为单数，填is playing。
4. 妈妈正在打扫房间，填am cleaning。
5. now提示用现在进行时，主语your sister为单数，一般疑问句将is提前，填Is; making。
6. now提示动作正在进行，主语he为单数，填is taking。
