課文詳注 Further notes on the text
1．happen to, 發(fā)生在……身上。
What happened to you yesterday? 你昨天出什么事了？
2．a(chǎn) friend of mine, 我的朋友之一。
相當(dāng)于one of my friends，但前者比后者顯得更為親切。
3．After they had entered the house, they went into the dining room. 他們進(jìn)到屋里后，走進(jìn)了飯廳。
After they had entered the house 是時(shí)間狀語(yǔ)從句，had entered 是過(guò)去完成時(shí)結(jié)構(gòu)。在以after引導(dǎo)的時(shí)間狀語(yǔ)從句中，用一般過(guò)去時(shí)或過(guò)去完成時(shí)沒(méi)有多少差別。如果強(qiáng)調(diào)從句的謂語(yǔ)動(dòng)作在主句的謂語(yǔ)動(dòng)作之前完成，就用過(guò)去完成時(shí)。
4．turn on, 打開(kāi)，擰開(kāi)（電視、水源、煤氣等）。
其反義詞為 turn off（關(guān)上）。
語(yǔ)法 Grammar in use
過(guò)去完成時(shí)
構(gòu)成： had 過(guò)去分詞。
過(guò)去完成時(shí)主要用于表示兩個(gè)事件中一個(gè)發(fā)生在前，或者說(shuō)是表示較早的過(guò)去。常與現(xiàn)在完成時(shí)連用的副詞，如 already（已經(jīng)）， ever（曾經(jīng)），for 表示時(shí)間段的詞，just（剛剛）和never（從未）也常與過(guò)去完成時(shí)連用，以強(qiáng)調(diào)事件發(fā)生的先后次序。有時(shí)我們不一定非得用過(guò)去完成時(shí)表示先發(fā)生的事件，因?yàn)橐馑际智宄纾?
After I finished, I went home. 我做完后就回家了。
請(qǐng)看例句：
She went on holiday after she had taken the exam.
她考試后度假去了。
I ran to the platform quickly, but the train had already left.
我趕快跑到站臺(tái)上，但是火車已經(jīng)開(kāi)走了。
We had had dinner before they arrived.
他們到達(dá)之前我們就已吃飯了。
The patient had died when the doctor arrived.
大夫到達(dá)時(shí)病人已經(jīng)死了。
