Kevin+does+eye+exercises+at+that+tpime.改为否定句？

Question

如题所述

Answer 1

Kevin doesn't do eye exercises at that time
行为动词作谓语一般现在时态，主语是第三人称单数形式，变否定句是直接在主语后加助动词doesn't，原来的动词用原形。

注，根据at that time在那时
我认为应该是一般过去时态
即
Kevin did eye exercises at that time.
否定句是
Kevin didn't do eye exercise that time

Answer 2

这个英文句子改为否定句是：Kevin does not eye exercises at that tpime.
凯文那时不做眼保健操。

Answer 3

这句话由谓语动词单三形式的does可以判断，句子的时态是一般现在时，变成否定句时必须借助助动词does和否定副词not，再把谓语动词变回动词原形do。否定句:
kevin doesn't do eye exercise at that time.本回答被网友采纳
