1. Are, working; Yes, am. 2. is , watching 3. Why doesn’t . 4. not expensive
5. What , going .
1. Are, working; Yes, am. 根据题目要求，疑问句应该是“你正在工作吗？”第一人称Ｉ要变为第二人称you，现在进行时中的现在分词doing不变，照抄下来。肯定回答用Yes.
2. is , watching now提示用现在进行时，主语是第三人称，故填is , watching。
3. Why doesn’t . 对because提问用疑问词why,特殊疑问句的构成为：特殊疑问词＋一般疑问句，故填Why doesn’t。
4. not expensive即同义词转换，cheap =" not" expensive。
5. What , going . 对“做什么”提问用疑问词What，be going to do…是一般将来时。
