比較while, when, as
1）as, when 引導(dǎo)短暫性動(dòng)作的動(dòng)詞。
just as / just when / when i stopped my car, a man came up to me.
2）當(dāng)從句的動(dòng)作發(fā)生于主句動(dòng)作之前，只能用when 引導(dǎo)這個(gè)從句，不可用as 或 while。
when you have finished your work, you may have a rest.
3）從句表示"隨時(shí)間推移"連詞能用as，不用when 或while。
as the day went on, the weather got worse.
日子一天天過(guò)去，天氣越變?cè)綁?br>
