由when,while,as引導(dǎo)的時(shí)間狀語(yǔ)從句(1)when引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)表示“當(dāng)……的時(shí)候”。從句謂語(yǔ)動(dòng)詞可以是延續(xù)性動(dòng)詞也可以是短暫性動(dòng)詞。如：IstudiedEnglishwhenIwasyoung.

Whenwemeet,Iwilldiscussitwithyou.

when還可以表示突然發(fā)生某事，常譯為“正在……忽然……”。如：Iwasdoingmyhomeworkwhentherewasabignoiseoutside.(2)while引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)表示“當(dāng)……的時(shí)候”。從句和主句中的謂語(yǔ)動(dòng)詞一般是延續(xù)性動(dòng)詞。有時(shí)也可表示主句的動(dòng)作發(fā)生在從句動(dòng)作進(jìn)行的過程中，此時(shí)主句中的謂語(yǔ)動(dòng)詞通常是短暫性動(dòng)詞。如：Helistenedcloselywhilesheread.Whilethediscussionwasstillgoingon,thebosscamein.(3)as引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)表示“當(dāng)……時(shí)，一邊……一邊……，隨著……”。這時(shí)主、從句的兩個(gè)動(dòng)作幾乎同時(shí)發(fā)生，或者一個(gè)動(dòng)作隨著另一個(gè)動(dòng)作的變化而變化。如：HelookedatmecuriouslyasIopenedthedoor.“I’llcallyouatnine,”hesaidashelefther.Astimepassed,thingsseemedtogetbetter.2.until,till引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)，在肯定句中表示“做某事直至某時(shí)”，在否定句中表示“直至某時(shí)才做某事”。如：Let’swaittilltherainstops.Ididn’thaveabikeuntilIwas17.
