单选题In the morning of November 18, 1755, an earthquake shook Boston. John Winthrop, a professor at Harvard College, felt the quake and woke up. "I rose," he wrote, "and lit a candle, looked at my watch, and found it to be 15 minutes after four." John Winthrop went downstairs to the grandfather"s clock. It had stopped three minutes before, at 4:11. Except for stopping the clock, the quake had only thrown a key from the table to the floor. The clock had stopped because Winthrop had put some long glass tubes he was using for an experiment into the case for safekeeping. The quake had shocked the tubes over and blocked the pendulum. Winthrop, therefore, had the exact time that the earthquake had hit Boston. He looked at the key on the floor. The quake had thrown it forward in the direction of the quake"s motion by a shock coming from the northwest, perhaps in Canada.

单选题Smoking is very prevalent (普遍的) in the West, both by men and by women. But there are still people who do not smoke and who dislike the smoke of others. Be careful not to smoke in such a way or in such a position that your smoke blows into others faces. If you are a guest in a home where no others are smoking, it is better to refrain from smoking. If you think they would not mind your smoking, you may say, "Would you mind if I smoked?" and await their assurance (承诺) before lighting up. There are many places where people do not or should not smoke: public meetings, movies and plays, stores, ball-rooms, trains (except in the smoking car), buses (except in the back seats), at the dinner table (except when invited by the hostess near the end of the meal to do so). Many people feel that ladies should not smoke on the street. Be a clean smoker—use an ash receiver and put out the cigarette completely when you are finished. Be very careful where you put down your lighted cigarette; it is thoughtless and inconsiderate to allow your cigarette to bum the furniture or table covers.
