在英语越来越普及的今天，学好英语成了大学生的首要学习目标。为了帮助大家顺利通过英语考试。特收集以下题目：
Most earthquakes occur within the upper 15 miles of the earth’s surface. But earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much. In comparison with the total number of earthquakes each year, the number of disastrous earthquakes is very small.
The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set, it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir, Morocco, was not strong enough to be recorded on distant instruments, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.
The United Nations has played an important part in reducing the damage done by earthquakes. It has sent a team of experts to all countries known to be affected by earthquakes. Working with local geologists and engineers, the experts have studied the nature of the ground and the type of most practical building code for the local area. If followed, these suggestions will make disastrous earthquakes almost a thing of the past.
There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic sea waves, or tsunamis. (These are often called tidal waves, but the name is incorrect. They have nothing to do with tides.)
In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them “tsunamis”, meaning “harbor waves”, because they reach a sizable height only in harbors.
Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An adequate warning system is in use to warn all shores likely to be reached by the waves.
But this only enables people to leave the threatened shores for higher ground. There is no way to stop the oncoming wave.
1. Which of the following CANNOT be concluded from the passage?
A. The number of earthquakes is closely related to depth.
B. Roughly the same number of earthquakes occur each year.
C. Earthquakes are impossible at depths over 460 miles.
D. Earthquakes are most likely to occur near the surfaces.
2. The destruction of Agadir is an example of
A. faulty building construction
B. an earthquake’s strength
C. widespread panic in earthquakes
D. ineffective instruments
3. The United Nations’ experts are supposed to_______
A. construct strong buildings
B. put forward proposals
C. detect disastrous earthquakes
D. monitor earthquakes
4. The significance of the slow speed of tsunamis is that people may
A. notice them out at sea
B. find ways to stop them
C. be warned early enough
D. develop warning systems
1. C)
可用解除法来找出此题的谜底。题干要求找出无法从文章中得出结论的一项。按照文章第一段第一句到第三句可知“跟着深度的增添，地震的数目随之削减”，可得出结论选项A“地震的数目和深度慎密亲密相关”，故解除。按照文章第一段第五行“…
in a month, but the yearly average does not vary much.”(接近地表处地震的发生频率可高磁缦憧月一百多次，可是年平均地震数目却转变不大。)可解除选项B.
Roughly the same number of earthquakes occur each year.(每年发生的地震数目大致不异);按照文章第一段可得出以下结论：地震首要发生在离地表十五公里典型围之内，尽管深达460公里的深处也有地震发生，可是每隔几年才发生一次。故可解除选项D Earthquakes are most likely to occur near the surfaces.(地震首要发生在地表处)。综上可知，选项 C 为正确谜底。
2. A)
文章第二段首先举例声名运用分歧的建筑体例和材料所建筑的衡宇的抗震能力是分歧的，进而就提到了发生在摩洛哥Agadir的地震虽然震级不大，却摧毁了整个城市，而良多更强烈的地震所造成的损失踪却很小，由此作者得出结论：如不美观建筑物建筑得好而且建在坚贞的地面上，那么它就能抵御地震;地震中大大都的衰亡是因为不良的建筑结构或不妥的建筑地址造成的。由此可知作者引用摩洛哥的Agadir的杀绝主若是要声名不良的建筑结构(faulty building construction)，故选项A为正确谜底。
3. B)
按照文章第三段可知，连系国在地震减灾方面起到了很是主要的浸染，它派出了良多地震专家到饱受地震袭扰的国家，与当地的地质学家和工程师一路研究当地的地质机关及适合当地的适用的建筑律例，而且如不美观这些专家提出的建议获得采纳，灾难性的地震就会成为历史。是以这四个选项中，最合适的是B put forwardproposals “提出建议”，故其为正确谜底。
4. C)
按照文章最后一段，海啸的移动速度迟缓，使人们得以及早发现，以提前向沿岸的居平易近发出警告，分开海边到高地去，可是人们却无法阻止到来的巨浪。故选项C be warned early enough为正确谜底。
