Question

5．Check out our tsunami（海嘯） facts and learn some interesting information related to these great walls of water that can cause so much destruction．Find out what causes tsunamis and read about some notable recent examples of tsunamis that have occurred around the globe．
Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions．
 As a tsunami approaches the shore，water may move back from the coast．If it is shallow enough，the water may be pulled back hundreds of meters．If you are in the area，observing this is a good indication that a tsunami is on the way．
Regions in tsunami danger zones often have warning systems in place to give people as much time to evacuate（撤離）as possible．
When tsunamis hit shallow water （often near the coast），they slow down but increase in height．
An earthquake in the Indian Ocean off Indonesia in December 2004 caused a tsunami that killed over 200，000 people in 14 countries．
In March 2011，the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15，000 people．
The tsunami waves created by the Tohoku earthquake reached heights of over 40 meters（131feet）in some areas，wiping out coastal towns and causing a number of nuclear accidents．
The Japanese word"tsunami"literally means"harbour wave"．
Tsunamis are sometimes referred to as tidal（潮水的）waves but this term has fallen out of favour because tsunamis are not related to tides．
25．How many reasons are mentioned in the passage that may cause tsunamis？B
A．One．B．Two．C．Three．D．Four．
26．which of the following shows a tsunami is coming soon？B
A．An earthquake takes place．
B．The water marches towards the coast．
C．The water near the shore is pulled back．
D．The water near the shore is very shallow．
27．What can we learn from the passage？D
A．The word"tsunami"is from British English．
B．The term"tidal wave"is used more often than"tsunami"．
C．Sone nuclear accident happened after Indonesia tsunami．
D．More people died in Indonesia tsunami than in Tohoku tsunami．
28．The passage is developed mainly byA．
A．listing the facts             
B．giving some examples
C．providing some numb ers     
D．making some conclusions．

Answer 1

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了海嘯發(fā)生的原因并通過例子來描述海嘯給人類所帶來的危害．

解答 25．B．細節(jié)理解題．根據第四段：Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions．可知導致海嘯的原因有地震和火山爆發(fā)這兩種，故選B．
26．B．細節(jié)理解題．根據第二段As a tsunami approaches the shore，water may move back from the coast．If it is shallow enough，the water may be pulled back hundreds of meters可知水向海岸行進顯示海嘯即將到來；故選B．
27．D．細節(jié)理解題．根據文章倒數第三段和倒數第四段Indonesia in December 2004 caused a tsunami that killed over 200，000 people in 14 countries．In March 2011，the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15，000 people可知，在印度尼西亞海嘯中死亡的人比在東日本大海嘯中死亡的人多，故選D．
28．A．推理判斷題．根據文章的最后幾段In March 2011，the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15，000 people可知，作者主要是通過列舉事實展開文章，故選A．

點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據文章事實進行合乎邏輯的推理判斷．
