下面我們再用同樣方式作一組練習復習動詞詞組和表明時間的從句. 練習的 內容是說鮑勃的父親在得肺癌之前老是抽雪茄, 后來住院的時候戒了, 出院 以后又改抽煙斗的事情. 請你根據問題作肯定的答覆. 回答之后請你聽老師 念正確答案.
M: Did Bob's father use to smoke cigars before he got lung cancer?
F: Yes, he used to smoke cigars before he got lung cancer.
M: Did he try to put it off when he was told to quit?
F: Yes, he tried to put it off when he was told to quit.
M: Did he finally give up smoking cigars when he was in the hospital?
F: Yes, he finaliy gave up smoking cigars when he was in the hospital.

F: Yes, he took up pipe smoking soon after he got out of the hospital.
M: Did he keep on smoking until the day he died?

下面我們再練習說明時間的從句. 練習的作法是老師用 when 提出一個 過去 時態問題,比方"美國印地安人是什么時候開始種煙草的?"When did American Indians start growing tobacco? 然后老師說: "哥倫布到美洲大陸以前" before Columbus came to America, 你就回答說: They started growing tobacco before Columbus came to America. 老師也可能用 how long 提出現在完成時態問題, 比方"煙草工業對美國經濟具有重要性已經有多久了?" How long has the tobacco industry been important for America's economy? 然后老師說:"自從殖 民地時代農民種植煙草外銷以來" ever since colonial farmers grew tobacco for export.你就回答說:It has been important for America's economy ever since colonial farmers grew tobacco for export. 這組練習的內容跟美國煙草工業和 美國人抽煙的情況有關系, 比方人們發現了某些疾病跟抽煙有關連以后, 香 煙公司就開始賣有過濾嘴的香煙, 而政府也制定了一些有關抽煙的法規等 等. 在這組練習里你可以學到一些有用的詞匯, 比方 "降低" decline, "制定" institute, "法規" regulation, "主要" major, "目標"aim, "牌子"brand,"過濾嘴" filter, "疾病"ailment等等. 這組練習比較難, 請你在回答問題之前特別注意聽, 每回答一句, 老師就會念出正確答案給你聽.
