题目内容

Krakatau Volcano (喀拉喀托火山) is on a small island in Indonesia. It had been peaceful for about 200 years before it erupted (爆发) in 1883.

The first signs of the activity of the volcano appeared in May 1883, when fire and smoke could be seen at the top of the mountain. Great noise could be heard even in Jakarta, a hundred miles away. Later the activity grew much greater. The peak (山顶) was covered with smoke and fire; the smoke at one time was seventeen miles high in the air. The lava—soft and hot rock—shot up into the air and rolled down the sides of the mountain.

The mouth of the volcano was not at the peak of the mountain but on its side, close to the sea. As it grew bigger and bigger with the eruption, the sea water got into it. When the sea water reached the lava inside the volcano, it made the upper part of the lava colder and harder. And this sealed off (封住) the rest of the lava below. As the inside of the lava could not break through the seal, the pressure (压力) built up until the mountain blew up.

The eruption of the volcano was followed by several earthquakes which brought about bad results. About 36,000 people were killed and many towns and villages near the sea were completely destroyed by the great waves which the earthquake caused.

1．Give the correct order of the course of volcano eruption.

①The peak was covered with smoke and fire.

②Fire and smoke could be seen at the top of the mountain.

③Great noise could be heard a hundred miles away.

④The lava shot into the air and rolled down the sides of the mountain.

A．①②③④ 　　　　 B．①③②④

C．②③①④ 　　　　 D．④①③②

2．What makes the volcano erupt?

A．The sea water which goes into the volcano.

B．The lava (岩浆)．

C．The pressure which is bigger and bigger.

D．All of the above.

3．Where is the mouth of the volcano?

A．At the peak of the mountain.

B．On the side of the mountain near the sea.

C．At the foot of the mountain.

D．Inside the mountain.

1．C　从文章第二段可知顺序为②③①④。

2．D　火山爆发是A、B、C三项共同作用的结果，并非由其中的一项原因即可爆发。

3．B　细节考查题。根据文章第三段第一句话“The mouth of the volcano was not at the peak of the mountain but on its side, close to the sea.”可断定答案为B项。

The huge explosion at Krakatau was the result of two different factors. One was that the volcano had not broken out for some time and so at the very center of the volcano there was an huge plug of lava, this acted like a cork(塞子) in a bottle, stopping the pressure below from being released(释放). The second factor was that ocean water entered the very centre of the volcano as the explosions became more violent. This caused superheated steam to build up enormous pressure and this was finally released in the largest explosion of all on August 27, 1883. The sudden release of the pressure sent huge amounts of ash, rock and dust into the sky. Some of the ash rose 80km into the air and traveled around the Earth causing brightly coloured sunsets for several years.
Krakatau almost disappeared; for many years after this explosion, it remained very quiet. However, there was still activity going on under the sea and on 25 January, 1925, a small volcanic cone appeared above the surface of the water. This new volcano was named Anak Kmkatau, or Child of Krakatau. Over the following years, the size of the island grew larger, by 1959, the island was 300 metres above the surface of the sea. The volcanic activity has continued and the latest eruptions were in 1995.
There is no doubt Krakatar will continue to grow and there is also strong evidence that at some point in the future there will be another violent explosion. Krakatau is in a part of the world where the surface of the Earth is unstable and is always moving and cracking. If, in the future, another “cork” becomes fixed in the centre of the volcano, the pressure will build up. A series of a smaller explosions will allow sea-water into the centre of the volcano and once again the result will a terribly destructive explosion.
66. The latest eruptions were in_______.
A.1925           B. 1959           C. 1995          D. 1983
67. The pressure under the volcano can not be released because _______
the plug looks like a cork in a bottle
the volcano hasn’t broken out for some time
the center of the volcano is blocked(堵塞) by lava
the temperature of the steam is not high enough.
68. We can infer from the article that Krakatau volcano________
A. has broken out three times               B. never dies but continues to be active
C. will kill many people again in the future    D. is always moving and growing above sea.

The following card includes a brief summary and a short assessment of a research paper. It can provide a guide for further reading on the topic.

In this article Trevor et al. review the influences of pay and job opportunities in respect of job performance, turnover rates and employees' job attitude. The authors use data gained through organizational surveys of blue-chip companies in Vancouver, Canada to try to identify the main cause of employee turnover and whether it is linked to salary growth. Their research focuses on assessing a range of pay structures such as pay for performance and organizational reward plans. The article is useful as Trevor et al. suggest that there are numerous reasons for employee turnover and a variety of differences in employees' job attitude and performance. The main limitation of the article is that the survey sample was restricted to mid-level management, thus the authors indicate that further, more extensive research needs to be undertaken to develop a more in-depth understanding of employee turnover and job performance. As this article was published in a professional journal, the findings can be considered reliable. It will be useful additional information for the research on pay structures.
1. The research paper published is primarily concerned with
A. the way of preventing employee turnover
B. methods of improving employee performance
C. factors affecting employee turnover and performance
D. pay structures based on employee performance
2. As is mentioned in the card, the limitation of the research paper mainly lies in that .
A. the data analysis is hardly reliable
