timeyesterday.昨天晚上9点格林一家人没有看电视。TheGreenswerenotwatchingTVat9:00lastnight.—昨天这个时候你在看书吗？

—是的，我在看书。/不，我没在看书。—Wereyoureadingabookatthistimeyesterday?—Yes,Iwas./No,Iwasn’t.例句二、when与while引导的时间状语从句相同点：when和while均可作连词，意为“当……的时候”，引导时间状语从句。1.when的用法(1)指时间点，也可指时间段，其从句的谓语动词

既可以是延续性的，也可以是非延续性的。例句：当交通灯是绿色的时候，你可以过马路。

Youcanwalkacrossthestreetwhentraffic

lightsaregreen.(2)引导的从句的谓语动作既可与主句谓语动作同时发

生，也可以是之前或之后发生。例句：迈克给我打电话时，我正在跟乔讨论一道数

学题。

IwasdiscussingamathproblemwithJoewhenMikecalledmeup.(3)若主句是一般将来时，从句用一般现在时表示将来。例句：我到了上海会给你打电话。I’llcallyouwhenIarriveinShanghai.2.while的用法(1)指时间段，其从句的谓语动词必须是延续性的。例句：请在你的父母健在的时候爱他们，不要等到

一切都太迟了。Loveyourparentswhiletheyarealive.Don’twaituntilitistoolate.(2)强调主句动作发生时，从句动作正在进行，常用

while引导从句。主句常用一般过去时或一般现在

时，从句常用进行时。例句：当我正在河边钓鱼时，我看到附近有一

条空船。WhileIwasfishingbytheriver,Isawan

emptyboatnearby.(3)强调主、从句动作同时进行，常用while引导从句，

此时主从句常用进行时。例句：康康在上音乐课的时候，Darren在爬山。
