A very rapid increase in the number of ships sailing between American and European ports began almost immediately after the end of the war of 1812 in order to meet the new need for the regular rapid transportation of mails, light goods, and passengers. It was the increase in emigration (移民) to America that for the first time made the carrying of passengers across the Atlantic more advantageous than the transportation of heavy goods. A new type of sailing ships, the packet, appeared to meet this new demand, and the ex-tent (程度) of the demand very soon caused strong competition among several packet lines. The earliest of these was the Black Ball Line opened in New York in 1816, only a year after the war. The service of the famous line started with four of the new fast packetseach of 400 to 300 tons/the Pacific, the Amity, the James Cooper, and the William Thompson. During the first twenty years o5 service, the average time from New York to Liverpool was 23 days and the average trip back to New York took 40 days. By the middle of the century, packets had increased in size between 909 and 1 000 tons, and their speed had increased. The Red Jacket once sailed from New York to Liverpool in 13 days 11 ( 1 /2) hours. The Mary Whiteridge took 4 (1/2) hours off this record on a run from Balti more to Liverpool. Such speeds were far greater than the average of from 19 to 21 days to Liverpool and from 30 to 35 homeward to New York, but the packets bad still set a new record for transoceanic (crossing an ocean) travel. No wonder that steamships, the first of which tried to compete with the packets itl 1838, only began to replace them in the 1850s.

73. From the passage we can infer the writer’s feeling about the packet is one of the following. Which one do you think is the best answer? 73. B

A. ft is not surprising that tile steamship was not used until it replaced the pack et in 1850s.

B. The packet was so nice that steamship could not replace it until many years later.

C. Fhc packet was not good and so the advanced steamship was used instead of it finally.

A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”. and the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not sim-ply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them thc earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.

The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide (二氧化碳) in the at-mosphere doubles, there will probably be a rise in the earth’s temperature of between I and 4℃;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.

65. According to the passage, we can know “greenhouse effect” means_______.  65. B

A. the way in which gases are used for keeping plants warm

B. a natural course that is to a certain degree useful to us

C. the way “greenhouse gases” trap heat on the earth

A. all plants would not grow on our planet

B. soil would reduce the temperature by 30 degrees

C. man would breathe the cleaner air

D. people eouldn’t live in the earth

67. Which of the followiring is not true? 67. D

A. Burning too much coal and oil produces lots of greenhouse gases.

B. It has become warm on thc earth now than in the past.

C. Gases put into the atmosphere now will affect the earth years later.

D. The temperature in a greenhouse is as high as that in the atmosphere.

68. Suppose the earth’s temperature rose by 3 degrees, _______.  68. A

To tell you the truth, I’m not interested in owning a cellular (网络) phone. Except for use in an emergency (紧急情况), for ordinary cellular phone service is very expen-sire. How would I get help if I were in trouble or in danger? A goodd friend mid about a product she thought would settle my problem. It’s the SOS phone-a it celhdar phone serv-ice designed for emergency use.

With the touch of a hutton, the SOS phone will connect me to a roadside emergency service, a 91t service or a trained SOS operator, 24 hours a day. If I ever need help. I know it’s just a phone call away.

By pressing the “Tow” button, I’ll bc connected with my emergency roadside service provider. Or, if I don’t have one, the SOS operator can suggest one to me and get in tou-ch with them immediately.

The “911” button wdi connect me to 911 emergency service in my area-best of all, the call is completely free!

If I just want to call home to tell my husband and children something necessary, I can, by pressing the “Call” hutton, I’ll reach an operator. When I ask the operator to call home, I’ll be connected automatically (自动地). And because the Call Center has my 10 most-used phone numbers, I don’t even have to recite the numbers.

Unlike ordinary cellular phone plans, the SOS phone doesn’t have any minimum us age requirements (底价) or other promises that could change the price i expect to pay each month.

Why not try it yourself!

The journey two naval (海军) officers made some time ago to tile very deepest point on the earth makes us realize how much of the world still remains to be explored (探测). The two men went down screen miles to the bottom of the Pacific Ocean h~ide a small steel ball called a “bathy-scaphe” to find out if there are any ocean currents (急流) or signs of life.

It was necessary to set ont early, so that the bathyscaphe would come to the surfacc in daylight, and so be easily found by the mother ship which would be waiting for it. The divers began preparations at dawn and soon afterwards, when all was ready, the steel ball disappcared under the surface of the water.

In time, the temperature dropped to freezing-point and the men trembled inside the hall. They kept in touch with the mother ship by tclephone describing how they felt. Then, at a depth of 3 000 feet, the telephone stopped working and they were quite cut off from the outside world. At 30 000 feet, the men were surprised by a sudden, loud noise-even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the bathyscaphe touched the soft ocean floor raising a big cloud of “dust” made up of different kinds of small, dead sea animals. Here, powerful lights lit up the, dark water and the men were surprised to sec fish swimming just above them quitc untroubled by thc very large wate-pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the weak but clear voices of the officers were heard on thc mother ship. After a stay of thirty minutes the men began their journey up, arriving three hour later, cold and wet through, but none the worse for their experience.

56. The officers started their journey at dawn___.  56. D

A. because they wanted to return to the mother ship in twenty four hours

B. because the sea then was calm

C. when the sun was not too strong

D. so that they could return before dark

D. powerful lights can not be turned on at the ocean floor without killing fish

59. Which of the following is closest in meaning to “They were cold and wet through, but none the worse for their experience”? 59. D 

A. They were cold and wet through, which was the worst thing of all.

B. They were even worse than cold and wet through at the bottom of the sea.

C. Considering what they had just experienced, being cold and wet through was not too bad.

D. For such an experience, being cold and wet through was not bad for them at all.
