错滴!
while前后是两个句子.一般时态一致.
Some people read books while others have sports.
开心每一天哦!如果改成when呢when可以的,意义有所改变,但时态需改一下,when=at that time 【就在那时】while 【然而】表【前后对比】夲句还是while较好。怎么改Some people were reading books when others were having sports.Some people read books when others were having sports.行吗一般情况下,时间持续时间长的用过去进行,时间段的用一般过去,但夲句两个动作很难分清长短,故都用过去进行,也就是用while较好的原因。【表示对比】
