现在进行时表示某人正在做某事，它不仅有肯定式、否定式和一般疑问式，还有特殊疑问式。从陈述句变成疑问句可以从以下几个方面进行提问：

　　「对主语提问」

　　首先要看清楚句子的主语是表示人的词还是表示事物的词。如果主语是表示人的词，将该主语改为who；如果主语是表示事物的词，则改为what.例如：

　　①Wang Ping is playing football in the park now.

　　→Who is playing football in the park now？

　　②The horse is running fast.

　　→What is running fast？

　　「对句子的谓语提问」

　　现在进行时的谓语由is，am或are加动词的-ing形式构成。对句子的谓语部分进行提问，要使用疑问词 what，然后将原句的谓语动词改为 doing，最后可别忘了将原来的宾语去掉。例如：

　　Wang Ping is playing football in the park now.

　　→What is Wang Ping doing in the park now？

　　「对句子的宾语进行提问」

　　如果宾语是表示人的词，用whom提问；如果宾语是表示事物的词，用what提问，将whom或what 放在句首。例如：

　　①Wang Ping is playing football in the park now.

　　→What is Wang Ping doing in the park now？

　　②Tom is helping John over there.

　　→Whom is Tom helping over there？

　　「对句子的状语进行提问」

　　首先要弄清楚句子的状语是作什么用的。一般来说，表示时间的状语用when提问；表示地点的状语用where提问；表示做事方式的状语用how提问。例如：

　　①Wang Ping is playing football in the park now.

　　→When is Wang Ping playing football in the park？

　　②Wang Ping is playing football in the park now.

　　→Where is Wang Ping playing football now？

　　③They are working hard in the fields.

　　→How are they working in the fields？
