timeyesterday.昨天晚上9點(diǎn)格林一家人沒有看電視。TheGreenswerenotwatchingTVat9:00lastnight.—昨天這個時候你在看書嗎？

—是的，我在看書。/不，我沒在看書。—Wereyoureadingabookatthistimeyesterday?—Yes,Iwas./No,Iwasn’t.例句二、when與while引導(dǎo)的時間狀語從句相同點(diǎn)：when和while均可作連詞，意為“當(dāng)……的時候”，引導(dǎo)時間狀語從句。1.when的用法(1)指時間點(diǎn)，也可指時間段，其從句的謂語動詞

既可以是延續(xù)性的，也可以是非延續(xù)性的。例句：當(dāng)交通燈是綠色的時候，你可以過馬路。

Youcanwalkacrossthestreetwhentraffic

lightsaregreen.(2)引導(dǎo)的從句的謂語動作既可與主句謂語動作同時發(fā)

生，也可以是之前或之后發(fā)生。例句：邁克給我打電話時，我正在跟喬討論一道數(shù)

學(xué)題。

IwasdiscussingamathproblemwithJoewhenMikecalledmeup.(3)若主句是一般將來時，從句用一般現(xiàn)在時表示將來。例句：我到了上海會給你打電話。I’llcallyouwhenIarriveinShanghai.2.while的用法(1)指時間段，其從句的謂語動詞必須是延續(xù)性的。例句：請在你的父母健在的時候愛他們，不要等到

一切都太遲了。Loveyourparentswhiletheyarealive.Don’twaituntilitistoolate.(2)強(qiáng)調(diào)主句動作發(fā)生時，從句動作正在進(jìn)行，常用

while引導(dǎo)從句。主句常用一般過去時或一般現(xiàn)在

時，從句常用進(jìn)行時。例句：當(dāng)我正在河邊釣魚時，我看到附近有一

條空船。WhileIwasfishingbytheriver,Isawan

emptyboatnearby.(3)強(qiáng)調(diào)主、從句動作同時進(jìn)行，常用while引導(dǎo)從句，

此時主從句常用進(jìn)行時。例句：康康在上音樂課的時候，Darren在爬山。
