[单项选择]On the morning of November 18,1735, an earthquake shook Boston, Massachusetts. John Winthrop, a professor at Harvard College, felt the quake and awoke. "I rose," Winthrop wrote, "and lighting a candle, looked on my watch, and found it to be 15 minutes after four." John Winthrop walked quickly 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 mantel to the floor.
The clock had stopped because Winthrop had put some long glass tubes he was using for an experiment into the box for safekeeping. The quake had knocked 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.
This passage suggests that ______.
A. John Winthrop had difficulty in sleeping
B. earthquakes are common in Boston
C. Boston was a center for clock-making
D. John Winthrop was a scientist

[单项选择]Earthquake 　　How does an earthquake start 　　What makes an earthquake happen The rock of the earth’s crust (地壳) may have a fault’, a kind of break in the surface. 　　 　　The blocks which make up the earth move, and sometimes this may cause the sides of the fault to move up and down or lengthways (纵向地) against each other. When one piece of rock starts to rub on another with great force, a lot of energy is used. This energy is changed into vibrations (振动) and it is these vibrations that we reef as an earthquake. The vibrations can travel thousands of kilometers and so an earthquake in Turkey may be felt in Greece. 　　What to do during an earthquake At school 　　As soon as the earthquake starts, students should get under the desks immediately and wait until the teacher tells them it is safe to come out. The teacher should, at the same time, go immediately to the teacher’s desk, get underneath (在……下面) it and stay there till the danger is over. Students must not argue with the teacher
