II. Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. (1.0 point) Tsunamis, whose name derives from the Japanese expression for high wave in a harbour, are giant sea waves. These waves are quite different from storm surges. They are also referred to by the general public as tidal waves although they have nothing to do with tides. Scientists often refer to them as seismic sea waves, which is far more appropriate because they are often the result of undersea seismic activity. Tsunamis can be caused when the sea floor suddenly moves, during an underwater earthquake or volcano, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances, at speeds close to 700 kilometres per hour. In the open ocean, tsunami waves are not very high, often no more than one or two metres. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 metres. Question 36. The passage mainly discusses ___________ . A. Tidal waves B. tides C. tsunamis D. typhoon Question 37. All of the following is true about tidal waves EXCEPT _________ . A. They are as another name for tsunamis B. They are caused by sudden changes in high and low tides C. The name refer to the same phenomenon as seismic sea wave. D. Tsunami waves are not very high. Question 38. The word them in the passage refers to__________ . A. tsunamis B. Tidal waves C. sea waves D. storm Question 39. The word displaced in the passage is closest in meaning to _____________ . A. located B. not pleased C. moved D. struck Question 40. It can be understood from the passage that tsunamis _________ . A. are far more dangerous on the coast than in the open ocean B. cause severe damage in the middle of the ocean C. generally reach heights greater than 40 metres. D. cannot be caused when the sea floor suddenly moves
