Passage 2
It is a terrible illustration of man's weakness to nature, and the tsunami (海啸) that struck the Japanese coast in March, 2011 has illustrated the difficulty of fighting against natural disasters, even for a prosperous nation.
Totally preventing tsunami-damage is impossible. But there is much that can be done to minimize damage and loss of life. Measures that can be taken include designing solid buildings, and developing early-warning systems, public education programs and evacuation (疏散) strategies. Moreover, the approach of a tsunami is possibly picked up by the sensors of complicated international warning systems. Countries can use radio and television broadcasts as well as loudspeaker networks to warn the public.
But an early warning system depends on how far the tsunami strikes, if it's close by, the warning system is not going to be very effective. When people are faced with an unstoppable force like a tsunami the massive waves created by events like underwater earthquakes, the best course of action for them is to get inland and to the higher ground as quickly as possible.
The first paragraph tells us that ______.
第一段只有一句话，前半句便点明了段落的大意即“It's a terrible illustration of man's weakness to nature...”，接下来提到的2011年日本发生的海啸也是对此进行举例论证的，选项C是此句话的同义转述。故选C。
To prevent tsunami-damage, the following measures can be taken EXCEPT ______.
第二段主要讲了预防海啸的措施，第三句话所提到的designing solid buildings, developing early-warning systems, public education programs and evacuation strategies分别与选项A、B、C一一对应，只有选项D不正确。
According to the passage, which of the following can cause a tsunami?
文章第三段第二句“...an unstoppable force like a tsunami the massive waves created by events like underwater earthquakes...”中的the massive waves created by events like underwater earthquakes...是对海啸的解释说明，by后面正是引起海啸的原因，即underwater earthquakes。所以应该选C。
When a tsunami happens, the best course of action for people is to ______.
由文章最后一句“When people are faced with an unstoppable force like a tsunami...the best course of action for them is to get inland and to the higher ground as quickly as possible. ”可知，当面对海啸的威胁时，最佳的行动方案是尽可能快地撤到内陆地区或者上到更高的地方。所以选项B正确。
Which of the following statements is correct according to the passage?
由第二段第一句“Totally preventing tsunami-damage is impossible. ”可知，A选项错误。B选项内容文章并未提到，故也不正确。由第三段第一句可知，海啸靠得很近时，预警系统不会很有效果，故D选项不正确。由第二段的第四句“...the approach of a tsunami is possibly picked up by the sensors of complicated international warning systems. ”可知，C选项正确。
