根据权威语法规则,用现在进行时态(be动词+动词ing形式)构造肯定、否定、疑问句的10个例句如下:
肯定句 - I am reading a book now.(我现在正在读书。)
- She is cooking dinner.(她正在做晚餐。)
- They are playing soccer on the playground.(他们正在操场上踢足球。)
否定句
- He isn't watching TV.(他现在没有在看电视。)
- The students aren't listening to the teacher.(学生们现在没有在听老师讲课。)
- She isn't doing her homework.(她现在没有在做作业。)
疑问句
- What are you doing?(你正在做什么?)
- Is he cleaning the room?(他正在打扫房间吗?)
- Are they going to the party?(他们要去参加聚会吗?)
说明:
肯定句以be动词(am/is/are)+动词ing形式构成,如"I am..."、"They are..."等。- 否定句在be动词后加not,如"isn't"、"aren't"等。- 疑问句需将be动词提前,如"What are you doing?"。以上例句均符合现在进行时的基本结构,且涵盖不同主语和场景。
