1. 确认问句的主语和时态,根据答语构思必要的疑问词和助动词。
2. 以疑问词开头,接上助动词和主语,再倒装句子。例如:答句:I went to the park with my parents.问句:Who did you go to the park with?答句:He is reading a book at home.问句:What is he doing at home?答句:They were playing football in the playground.问句:What were they doing in the playground?
3. 如果答句中没有出现疑问词,可以根据答语中的动词和时间状语构成问句。例如:答句:She will visit her friends next week.问句:When will she visit her friends?答句:The cat is sleeping on the sofa.问句:Where is the cat sleeping?
