第Ⅱ卷 语篇综合训练
(一)阅读理解
Tsunamis are one of the most terrifying natural phenomena that the world suffers.The series of waves produced by the displacement (位移) of a large volume of water can be caused by several events, including earthquakes, underwater explosions and landslides.Once triggered (引发), a tsunami can hit the coast within minutes and its destructive power can be enormous.
At present,early warning systems rely on measuring the movement of dart buoys (浮标),which record changes in the sea level, or assessing the bottom water pressure of the developing tsunami.But they require the tsunami to physically reach the measurement location.The buoys could be fixed in the deep ocean, but this requires an unrealistically big number of buoys.Or people can fix the buoys along the shoreline, but due to the high speed of the tsunami, this method may leave no warning time for people on the land.
Instead, there is a new system using sound waves to predict tsunamis.Sound waves caused by an earthquake can travel much faster than the tsunami that has been triggered.Using standard underwater microphones, we can record these sound waves long before the tsunami arrives regardless of the direction in which the tsunami will travel.The sound signals come from changes in pressure, so what we actually analyze is a series of data on how the pressure is changing overtime.Though buoys also show changes in pressure, the tsunami front must actually reach the buoys to inform us that there is an increase in the water surface.By using underwater microphones, however, we only need to catch the sound signals.
Though the idea of using sound waves to predict tsunamis has been put forward previously, the key to our idea is a new mathematical method that can be used to analyze these recorded sound signals in near real-time.Once this is worked out, we can not only warn people of a tsunami but also more accurately estimate its size long before it reaches the shoreline.
语篇解读:本文是一篇说明文。文章通过讲述造成海啸的原因、海啸的破坏力以及当前海啸预警系统的弊端,从而介绍了一个新的实时海啸预警系统。
1.From paragraph 1, we know________.
A.what can trigger off tsunamis
B.how to predict tsunamis effectively
C.why tsunamis are the worst natural disaster
D.how to protect the coastal areas from tsunamis
解析:选A 细节理解题。根据第一段第二句“The series of waves produced by the displacement of a large volume of water can be caused by several events, including earthquakes, underwater explosions and landslides.”可知,我们可以知道什么会引发海啸。
2.What does the underlined word “they” in paragraph 2 refer to?
A.The dart buoys.
B.The changes in the sea level.
C.The changes in water pressure.
D.The present early warning systems.
解析:选D 代词指代题。根据第二段第一句“early warning systems rely on measuring the movement of dart buoys”可知,当前的预警系统需要海啸实际到达测量地点。“they”指的是“当前的预警系统”。
3.What can we infer about the new warning system from paragraph 3?
A.It has high accuracy.
B.It can increase warning time.
C.It can monitor changeable sea levels.
D.It can adapt to various water wave conditions.
解析:选B 推理判断题。根据第三段中的“Instead, there is a new system using sound waves to predict tsunamis ...in which the tsunami will travel.”可推知,新的预警系统是可以增加预警时间的。
4.What's the best title for the text?
A.Ways to Guard Against Tsunamis
B.Methods of Analyzing Sound Signals
C.A New Real-time Tsunami Warning System
D.Tsunami — The Most Terrifying Natural Disaster
解析:选C 标题归纳题。根据第三段第一句和最后一段第一句并结合全文内容可知,本文通过讲述造成海啸的原因、海啸的破坏力以及当前海啸预警系统的弊端,从而介绍了一个新的实时海啸预警系统。故C项“一个新的实时海啸预警系统”适合作文章标题。
