每課一句： 新概念第2冊第82課
今天我們接著來看第83課的“每課一句”。
一、課文原文
Lesson 83 After the elections
The former Prime Minister, Mr. Wentworth Lane, was defeated in the recent elections. He is now retiring from political life and has gone abroad. My friend, Patrick, has always been a fanatical opponent of Mr. Lane's Radical Progressive Party. After the elections, Patrick went to the former Prime Minister's house. When he asked if Mr. Lane lived there, the policeman on duty told him that since his defeat, the ex-Prime Minister had gone abroad. On the following day, Patrick went to the house again. The same policeman was just walking slowly past the entrance, when Patrick asked the same question. Though a little suspicious this time, the policeman gave him the same answer. The day after, Patrick went to the house once more and asked exactly the same question. This time, the policeman lost his temper. 'I told you yesterday and the day before yesterday,' he shouted, 'Mr. Lane was defeated in the elections. He has retired from political life and gone to live abroad!' 'I know,' answered Patrick, 'but I love to hear you say it!'

二、每課一句
The same policeman was just walking slowly past the entrance, when Patrick asked the same question.
注意這句話在結構上的安排：句中的when所引導的從句被置于句末可以起到一舉兩得的作用。
一方面，根據寫作中的尾重原理，一個句子的句末是最具強調效果的，所以when從句因此得到更好的強調，使得讀者的注意力落在了Patrick問了警察同樣的問題上。
另一方面，因為這么安排，使得本句話在結構上與文中的下一句話在結構上形成了呼應：
Though a little suspicious this time, the policeman gave him the same answer.
Though a little suspicious this time, the policeman gave him the same answer.
即前一句話句末的Patrick asked the same question與后一句話句末的the policeman gave him the same answer，在句子結構和邏輯含義上前后做到了很好的呼應，從而烘托出了Patrick反復問同一個問題而警察又給出同一個答復的戲劇效果。
三、更多拓展
When he asked if Mr. Lane lived there, the policeman on duty told him that since his defeat, the ex-Prime Minister had gone abroad.
注意這個句子結構相對復雜：
1、when引導的是時間狀語從句；
2、if又是when從句中所包含的賓語從句；
3、that引導的是賓語從句，用作主句動詞told的賓語；
4、since后接his defeat，用作that從句中的時間狀語。
1、when引導的是時間狀語從句；
2、if又是when從句中所包含的賓語從句；
3、that引導的是賓語從句，用作主句動詞told的賓語；
4、since后接his defeat，用作that從句中的時間狀語。
所以，整句話的實際主要成分是：
When ..., the policeman on duty told him that ... the ex-Prime Minister had gone abroad.
When ..., the policeman on duty told him that ... the ex-Prime Minister had gone abroad.
