Have you ever wondered?

1. Why do airplanes take longer to fly west than east?

It can take five hours to go west-east from New York(NY) to London bur seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet(喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.

2. What would happen if the gravity on Earth was suddenly turned off?

Supposing we could magically turn off gravity. Would buildings and other structures(建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hours. If you turn something around your head on a string（细绳）, it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.

60.What information can we get from the first passage?

A.It is jet stream that affects how fast airplanes fly

B.Planes go slower when they are moving with the wind

C.It takes more time to fly from NY to London than from London to NY

D.The yet stream always blows from the east to the west across the Atlantic

61.The word”shoot”underline in the 2^nd passage probably means “ ”

A.send for B.move quickly C.come out D.grrow quickly

62.It can be inferred that without gravity .

A.buildings and other structures would float away

B.trees and buildings would not easily fly off

C.something around your head would not fly away

D.everything outside buildings would fly off into space

63.Where can we most probably read in the text

A.In a reseach paper B.In a short story

C.In a travel magazine D.In a student’s book

The need to feed a growing population is putting much pressure on the word’s supply of water.With 97% of the word’s water too salty to be drunk or used in agriculture,the wordwide supply of water needs carefull management，especially in agriculture .Although the idea of a water shortage(短缺) seems strange to someone fortunate enough to live in a high rainfall country,many of the word’s agriculture industries experience constant water shortages.

Although dams can be built to store water for agriculture use in dry areas and dry seasons,the costs of water redistribution(重新分配) are very high.Not only is there the cost of the engineering itself,but there is also an envitonmental cost to be considered.Where valleys(山谷) are flooded to create dams,houses are lost and wildlife homes destroyed.Besides,water may flow easily through pipes to fields,but it cannot be transported from one side of the world to the other.Each country must therefore rely on the management of its own water to suply its farming requirements.

This is particularly troubling for countries with agricultural industries in areas dependent on irrigation(灌溉).In Texas,farmers’ overuse of irrigation water has resulted in a 25% reduction of the water stores.In the Central Vally area of southwestern USA,a huge water engineering project provided water for farming in dry valleys,but much of the water use has been poorly managed.

73.Saudi Arabia’s attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves.Because there is no rainfall in these areas, such reseWhich of the folloeing is true?

B.Most industries in the world suffer from water shortages.

C.The underground watet in Saudi Arabia might run out in 50 years.

D.Good management of water use resulted from the project in the Central Valley.

WWW. The text is mainly about________.

A.water supply and increasing population

B.warer use management and agriculture

The engineer Camilla Olivetti was 40 years old when he started the company in 1908. At his factory in Ivrea, he designed and produced the first Italian typewriter. Today the company’s head office is still in Ivrea, near Turin, but the company is much larger than it was in those days and there are offices all around the world,

By 1930 there was a staff of 700 and the company turned out 13.000 machines a year. Some went to customers in Italy, but Olivetti exported more typewriters to other countries.

After Adriano died in 1960, the company had a period of financial problem. Other companies, especially the Japanese, made faster progress in electronic technology than the Italian company.

In 1978, Carlo de Benedetti became the new boss. Olivetti increased its marketing and service networks and made agreements with other companies to design and produce more advanced office equipment.

　　American cities are similar to other cities around the world. In every country cities reflect the values of the culture. Cities contain the very best aspects of a society: opportunities for education employment and entertainment. They also contain the very worst parts of a society: violent crime racial conflict and poverty. American cities are changing just as American society is changing.

　　After World War II city residents became wealthier more prosperous. They had more children. They needed more space. They move out of their apartments in the city to buy their own homes. They bought houses in the suburbs areas near a city where people live. These are areas without many offices or factories. During the 1950s the American “dream” was to have a house in the suburbs.

　　Now things are changing. The children of the people who left the cities in 1950s are now adults. They unlike their parents want to live in the cities. Many young professionals doctors lawyers and executives are moving back into the city. Many are single; others are married but often without children. They prefer the city to the suburbs because their jobs are there; they are afraid of the fuel shortage; or they just enjoy the excitement and opportunities which the city offers.

This population shift is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these people do not have enough money to stay in the cities.

Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright , new future .Others see only problems and conflicts. One thing is sure：many dying cities are alive again.

64.What does the author think of cities all over the world ?

A. They are alive . B. They are hopeless.

C. They are similar D. They are different.

65.Why did American city residents want to live in the suburbs after World War Ⅱ?

A. Because older American cities were dying.

B. Because they were richer and needed more space.

C. Because cities contained the worst parts of society.

D. Because they could hardly afford to live in the city.

66. According to the 4^th paragragh, a great many poor people in American cities （）

A. are faced with housing problems

B. are faced to move to the suburbs

C. want to sell their buildings

D. need more money for daily expenses

67. We can conclude from the text that ( )
