参考答案
1.He usually goes to bed at 22:00. (改为一般疑问句)
he usually to bed at 22:00?
【答案】Does go
【详解】句意:他经常在晚上10点上床睡觉。句子时态是一般现在时,主语是第三人称单数,改为一般疑问句时,助动词用does,谓语动词用原形。故填Does;go。
2.She plays tennis and basketball. (改为否定句)
She tennis or basketball.
【答案】doesn’t play
【详解】句意:她打网球和篮球。plays是动词三单,变否定句时借助于助动词doesn’t,后面的动词用原形play。故填doesn’t;play。
