C
An earthquake happens when two plates（板塊） rub (碰撞) together. The earth plates travel in different directions and at different speeds. If one plate is slowly forced underneath the other, pressure builds up until the plates break apart. This process causes the ground to move. It is an earthquake. In other words, earth-quakes are the shaking of the earth’s surface caused by the earth’s rocky outer layer as a result of the energy stored within the earth. The strain within the rocks is suddenly released (釋放).
The damage an earthquake causes depends on where it is and the time it is happening. If an unpopulated region is struck, there will be low loss of life or property. If it hits a large city, there may be many in-juries and much destruction. Many of the areas at risk are largely populated now. Major earthquakes hitting those areas today could produce terrible damage.
Actually, there are several million small earth-quakes every year. Large earthquakes such as the 1964 Alaskan quake that measured 9.2 on the Richter scale, cause millions of dollars in damage. In the last 500 years, millions of people have been killed by earth-quakes around the world — including 240,000 in the 1976 Tangshan earthquake in China.
A 60-second or less earthquake can cause devastation that continues for years after the first tremor (小震). In 1972, a series of severe earthquakes struck Managua, Nicaragua. Fifteen years later, the city still looked the way it had a week after the earthquake hit, because the country did not have the necessary money to rebuild it.
The shaking of the earth is sometimes not the greatest disaster. It is in the ensuing fires and floods that often the greatest damage occurs. In the 1906 earthquake, it was the fires caused after it that did the majority of the damage. An earthquake can also destroy dams high above a city or valleys, causing floods to sweep down and sweep away everything in their path.
61.Which of the following is the main idea of the first paragraph?
A. An earthquake comes from inside the earth.
B. The earth has great energy in storage.
C. How the earth plates move.
D. How an earthquake happens.
62.How many examples are used in the passage to show the damage and destruction earthquakes cause?
A. Three. B. Four. C. Five. D. Six.
63. Which of the following is mentioned to show that an earthquake can kill too many people?
A. The 1964 Alaskan quake. B. The 1976 Tangshan earthquake.
C. The 1972 Managua earthquake. D. The 1906 earthquake.
64. The underlined word “ensuing” in the last paragraph probably means ______.
A. causing too much heat and great damage
B. causing many injuries and much destruction
C. happening as a result of another event
D. happening suddenly and unexpectedly
65. By giving the example in Paragraph 4, the author wants to show that ______.
A. an earthquake doesn’t last long B. the damage can last long
C. people in Managua suffered too much D. Nicaragua is still a poor country

The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the Earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?
1.What is mainly described in the passage?
A. A historic discovery. B. An event of imagination.
C. A research on space. D. A scientific adventure.
2.When the first piece hits the South Atlantic, it causes .
A. an earthquake B. damages to cities
C. an Earth explosion D. huge waves
3.Why can’t the northern half of the earth escape for long?
A. Because the land is covered with water.
B. Because the light and heat from the sun can not reach the Earth.
C. Because people there can not live at the temperature of zero.
D. Because wars break out among countries.
4.By giving the example of dinosaurs, the author tries to prove .
A. animals could not live in the cold climate
B. what happened 65 million years ago was an invented story
C. the human beings will die out in 2094
D. the Earth could be hit by other objects in space
