錯(cuò)滴!
while前后是兩個(gè)句子.一般時(shí)態(tài)一致.
Some people read books while others have sports.
開心每一天哦!如果改成when呢when可以的，意義有所改變，但時(shí)態(tài)需改一下，when=at that time 【就在那時(shí)】while 【然而】表【前后對比】夲句還是while較好。怎么改Some people were reading books when others were having sports.Some people read books when others were having sports.行嗎一般情況下，時(shí)間持續(xù)時(shí)間長的用過去進(jìn)行，時(shí)間段的用一般過去，但夲句兩個(gè)動(dòng)作很難分清長短，故都用過去進(jìn)行，也就是用while較好的原因。【表示對比】
