Have you ever heard the story of the four-minute miles? Many years ago, people believed that it was impossible for a human being to run a mile in less than four minutes until Roger Banister proved it wrong in 1954.

What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when someone, who doesn’t know how to swim, falls in deep waters? They drown. If an animal who has not learnt swimming could escape by swimming, why not you? Because you believe you will drown while the animal doesn’t.

Have you ever wondered why the letters are organized in a particular order on your keyboard? You might have thought it is to increase the typing speed. Most people never question it. But the fact is that this system was developed to reduce the typing speed at a time when typewriter parts would jam (堵塞) if the operator typed too fast.

These three cases show the power of our beliefs. There is no other more powerful directing force in human behavior than belief. Your beliefs have the power to create and to destroy. A belief delivers command to your nervous system.

I used a snake in my workshops for children to show them how unrealistic some of their beliefs are. Students of a school in India, said snakes are smooth and poisonous. After doing an exercise for changing beliefs, they handled my snake and found it to be dry and clean. They also remembered that only three types of poisonous snakes exist in India.

Did this story end the way you thought? Review your beliefs now and find out which ones you need to change.

A. he is afraid of water.                                  B. he hasn’t learnt to swim before.

C. he believes he will drown.                                    D. he don’t want to live in the world.

42. The author thinks that the letters organized in a particular order on your keyboard in order to ________.

A. save more space                              B. satisfy the operator

       Could we "terraform" Mars —that is, change its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could.Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers flowing into vast seas.And right here on Earth, we've learned how to warm a planet: just add greenhouse gases to its atmosphere.Much of the CO2 that once warmed Mars is probably still there, in frozen dirt and polar ice caps, and so is the water.

       Most of the work in terraforming, says NASA scientist Chris Mackay, would be done by life itself. "You don't build Mars," Mackay says."You just warm it up and throw some seeds." Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere; by warming the planet, they would release the frozen CO2, which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow.Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession (系列) of ecosystems ?first bacteria and lichens (地衣), which survive in Antarctica, later mosses (苔蘚), and after one thousand years or so, redwoods.Getting breathable oxygen levels out of those forests, though, could take thousands of years.

       However, Mars is in no immediate danger.Some space scientists recently recommended going to the moon or an asteroid (小行星) first, and pointed out the space agency lacks the funds to go anywhere.It didn't estimate the cost of gardening a dead planet.

72.What is the most essential to make Mars fit for living?

       A.Turn ice into flowing water.           B.Clean the dirty atmosphere.

       C.Make the atmosphere more suitable.    D.Go to the moon or an asteroid first.

73.What does the author think of the idea ofterraforming Mars?

       A.We could do it.        B.We couldn't do it.

       C.We should do it.       D.We shouldn't do it.

74.In the botanist's opinion, man needs to __________.

       A.enable Mars to clean its atmosphere

       B.build a greenhouse on Mars

       C.send some people to settle on Mars

       D.cultivate ecosystems from lower to higher life form

75.What is the best title for the passage?

       A.Making Mars the New Earth.     B.A Good Way to Change the Universe

       C.Humans' Great Power.        D.Terrible Science and Technology.

PART THREE: READING COMPREHENSION

Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.

A

At dawn on Friday, May 19, 1780, farmers in New England stopped to wonder at the pink color of the sun. By noon the sky had darkened to midnight blackness, causing Americans, still in the painful struggle of a prolonged war of independence, to light candles and tremble at thoughts of the Last Judgment. As the birds quieted and no storm accompanied the darkness, men and women crowded into churches, where one minister commented that “The people were very attentive.” John Greenleaf Whittier later wrote that “Men prayed, and women wept; all ears grew sharp . . .”

A recent study of researchers, led by Richard Guyette from the University of Missouri’s Tree Ring Laboratory, has shown that vast forest fires in the Algonquin Highlands of southern Ontario and elsewhere in Canada brought this event upon New England. The scientists have discovered “fire scars” on the rings for that year, left when the heat of a wildfire has killed a part of a tree’s cambium (形成層). Evidence collected also points to a drought that year. An easterly wind and low barometric pressure (低氣壓) helped force smoke into the upper atmosphere. “The record fits pretty close,” says Guyette. “We had the right fuel, the drought. The conditions were all there.”

Lacking the ability to communicate quickly over long distances, Americans in 1780 remained in the dark about the event, which had disappeared by the next day. Over the next several months, the papers carried heated debates about what brought the darkness. Some were the voices of angry prediction, such as one Massachusetts farmer who wrote, “Oh! Backsliding New-England, attend now to the things which belong to your peace before they are forever hid from your eyes.” Others gave different answers. One stated that a “flaming star” had passed between the earth and the sun. Ash, argued another commentator. The debate, carried on throughout New England, where there were no scientific journals or academies yet, reflected an unfolding culture of scientific enquiry already sweeping the Western world, a revolution nearly as influential as the war for independence from the English.

New Englanders would not soon forget that dark day; it lived on in folklore, poems, and sermons for generations.

56. New Englanders crowded into churches because they were frightened by         .

A. the pink color of the sun      B. the darkened sky at daytime

C. the Last Judgment on Friday       D. the American War of Independence

57. What can we infer about the event in New England on May 19, 1780?

A. Prayers remained silent and attentive.

B. Night birds no longer came out to sing.

C. People’s ears became sharper than usual.

D. Midday meals were served by candlelight.

58. According to the researchers, the origin of the event was         .

A. an east wind                  B. a severe drought

C. some burning fuel                 D. low barometric pressure

59. What can we know about the debates after the dark day?

A. They focused on causes of the event.

B. They swept throughout the Western world.

C. They were organized by scientific institutions.

D. They improved Americans’ ability to communicate.

60. What can be the best title for the text?

A. New England’s dark day.     B. Voices of angry prediction.

C. There is no smoke without fire.  D. Tree rings and scientific discovery.

    As bananas ripen, the green skin turns ye11ow gradually. Chemical changes occur in the f1esh of the fruit as well:starch(淀粉)changes to sugar;pectin(果膠)breaks down,losing its stiffness; and the f1esh softens.

    Is ripening fruit a self-contained system, or is the rate of these changes affected by the environment? We designed the experiment below to see if different atmospheres, produced by different packaging, affected the rate of ripening. You will vary the atmosphere surrounding unripe bananas and observe the effect on the ripening process。

    Now set up the bananas in their environments as follows:

1. Put two green bananas in a paper bag and fo1d the top over to seal out the air.

    2.Put one green banana and the very ripe banana in the other paper bag and fold over the top.

    3. Put two green bananas in a plastic bag and seal it.

    4. Wrap(包)one green banana tightly in a plastic bag.

    5. Leave one green banana exposed to the air.

    Leave the fruit a1one or five days to ripen. Ripening fruit“breathes”. This means that it takes up oxygen and gives off C02. Oxygen is extremely important and necessary for the chemical reactions involved in ripening. In addition, ripening fruit gives off another gas, called ethylene(乙烯). Not only is ethylene a product of ripening fruit, it also promotes the further ripening of the fruit.

Paper bags tend to keep the ethylene in, but they allow oxygen and ethylene to pass through slowly. Plastic bags do not allow the free flow of oxygen or ethylene. In this experiment, the green banana in paper bag with the ripe banana should ripen most quickly. The green bananas in the paper bag should ripen faster than the bananas in the plastic bag. The banana left exposed to air has an unlimited supply of oxygen, so it will turn brown most quickly. You will notice that the side of this banana that rests on the counter will ripen more quickly than the other sides, because it has the

closest contact(接觸) with its own ethylene. The banana that is tightly wrapped in plastic has no oxygen supply and should ripen most slowly. Now can you see why bananas are sealed in plastic in many supermarkets?

72. What makes the green banana in Bag 2 ripen more quickly than the ones in Bag 1?

A. Ethylene from the very ripe banana.            B. The free flow of oxygen or ethylene

C. C02 from the very ripe banana.                     D. The limitation of oxygen supply.

73. How can we slow down the ripening of bananas exposed to the air?

A. To rest them on the counter.                                   B. To keep them in the basket.

C. To put them on the ground.                                     D. To hang them up from the ceiling

74. It can be concluded from the passage that          .

A. the ripening banana is a self-contained system

B. the rate of ripening bananas is affected by the environment

C. wrapped bananas experience no chemical changes to ripen

D. ripening bananas give off oxygen, C0, and ethylene

75. Why are bananas sealed in plastic in many supermarkets?

A. To make them ripen more quickly.                B. To make them ripen more slowly.

C. To make banana flesh soften.                        D. To turn green bananas yellow.
