we are going to play chess after school

We are going to play chess after school.
改否定句：We aren't going to play chess after school.
就play chess after school划线部分提问:What are you going to do after class?（这是就play chess划线提问） When are you going to play chess?（这是就after class划线提问）
——ugly duckling it is!是不是填What a
不对,应该填写：what an,因为后面是ugly,元音字母开头的
