A store owner was putting a sign above his door that read “Puppies For Sale”. Signs like that have a way of   1   small children, and   2   enough, a little boy appeared under the store owner’s sign. “  3   are you going to sell the puppies for?” he asked.

The store owner replied, “Anywhere from $30    4   $ 50.”

The little boy   5   in his pocket and pulled out some   6  . “I have $ 2.37,” he said. “  7   I please look at them?”

The store owner   8   and whistled and out of the kennel (狗窝) came a lady, who ran down the aisle (过道) of his store   9   by five puppies. One puppy was   10  . Immediately the little boy singled out the puppy and said, “What’s   11   with that little dog?”

The store owner explained that the veterinarian (兽医) had   12   the little puppy and had discovered that it didn’t have a hip socket. It would always walk slowly and with difficulty. It would always be lame. The little boy became   13   “That’s the little puppy that I want to buy.”

The store owner said, “No, you don’t want to buy that little dog. If you really want him, I’ll just give him to you.”

The little boy got quite upset. He looked   14   into the store owner’s eyes, pointing his finger and said, “I don’t want you to give him to me. That little dog is worth every bit as much as all the other dogs and I’ll pay   15   price. In fact I’ll give you $2.37 now, and 50 cents a month    16   I have him paid for.”

The store owner answered, “You really don’t want to buy this little dog. He is   17   going to be able to jump and play with you like the other puppies.”

To his surprise, the little boy reached   18   and rolled up his pant leg to show a badly twisted, crippled (残疾的) left leg   19   by a big metal brace (支架). He looked up at the store owner and softly replied, “Well, I don’t run so well myself, and the little puppy will need someone who   20  !”

Some scientists warn that ice near the Earth’s Poles may indeed be melting. This “polar meltdown” may be the first sign that the Earth is heating up. We could be in very serious trouble if this trend continues. It is estimated that a meltdown of as little as 10 percent of Antarctica’s ice would raise sea levels around the globe by 4 to 9 meters. Floods would cover low-lying regions and turn coastal cities like New York and New Orleans into real life underwater world.

Scientists first predicted in the 1970s that heat trapped in the Earth’s atmosphere could cause a polar meltdown. Many now believe that human activities are turning up the heat. When we burn fossil fuels like coal and oil, we add carbon dioxide(CO2) gas to the Earth’s atmosphere. Cutting down trees also makes CO2 levels raise because trees normally soak up CO2 to make food. Scientists say higher CO2 levels strengthen the “greenhouse effect” and could increase the Earth’s temperature. In fact, CO2 levels have risen by 30 percent since the Industrial Revolution of the 18th and 19th centuries.

Over the past three years, satellite measurements have shown a sea level rise of about a quarter inch worldwide. “If nothing is done to reduce fossil-fuel pollution and global warming, sea levels will rise even more.” says geologist Richard Alley.

But even Alley admits that a polar meltdown would take time. The ice in Antarctica and Arctic locks up nearly nine times the volume of water contained in all the world’s rivers and lakes. These are such big “ice cubes” and it would probably take thousands of years to melt them.

Another scientist Charles Bentley doesn’t think a meltdown will happen at all. “Even if warmer temperatures begin to melt polar-ice,” he says, “the excess moisture would most likely be redeposit as snow.” In other words, the melted ice would evaporate into the atmosphere, refreeze, and fall as rain and snow over the Poles.

What consequence of global warming is mentioned in the passage?

A. More tropical storms.       B. More tropical diseases.

C. Changes in farm productivity.   D. Coastal flooding.

Which of the following statements does the second paragraph support?

A. CO2 in the atmosphere cannot keep the heat from escaping into space.

B. The increase of CO2 gas may warm the planet and help to melt polar ice.

C. Cutting down trees helps to greatly reduce CO2 levels.

D. The end of the short-lived age of fossil fuels is already in sight.

Geologist Richard Alley most likely agrees that _______.

A. the sea-level rise can be prevented by cutting back on energy-consuming activities

B. the recent breaking off of ice blocks from Antarctica is just a natural part of a long-term cycle

C. Antarctica temperatures have significantly changed since the Industrial Revolution

D. the polar meltdown may be an accidental change of climate rather than a sign of global warming

Charles Bentley believes that a polar meltdown will not occur because _______.

A. governments around the world are beginning to reduce CO2 levels in the air

B. a melting of the polar ice cannot be achieved with the present technologies

C. the melted ice in the polar areas would change into snow and rain over the Poles

D. the sun’s heat would have no chance of being absorbed by the polar ice

In which paragraph does the author mention the immense quantities of polar ice?

A. In the second paragraph.   B. In the third paragraph.

C. In the fourth paragraph.    D. In the fifth paragraph.

A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to evade policemen after a bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into the home of Mary Parnell. Police say he didn’t touch Parnell but that she died after suffering a heart attack that was caused by terror. Can the guy be held responsible for the woman’s death? Prosecutors(公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime like robbery—even if he or she doesn’t kill someone on purpose.

But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.

Absolutely, no question about it.

The body has a natural protective method called the fight-or-flight response(战或逃反应), which was originally described by Walter Cannon，the chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the autonomic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to primitive humans. However, in the modern world there is obvious decline of the fight-or-flight response.

The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is toxic in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death. Kidney failure, liver failure, those things don’t kill you suddenly.

By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in intercourse or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead. For about seven days after the 9/11 terrorist attacks on the World Trade Center and Pentagon there was an increase of sudden cardiac death among New Yorkers.

Why the Charlotte, N.C., man was charged?

A. Because he threatened the policemen to kill an old woman.

B. Because he caused an old woman’s terror and she died.

C. Because he beat an old woman and caused her heart attack

D. Because he murdered an old woman while robbing a bank.

Which of the following about the fight-or-flight response is true?

A. The fight-or-flight response was raised and proved by Martin A. Samuels.

B. It is a natural protective method that can’t be found in all creatures but humans.

C. The ancient humans had a superior fight-or-flight response than modern ones.

D. The fight-or-flight response is beneficial to both our actions and organs.

What activity can we infer is less likely to damage the organs?

A. Winning a big lottery.                   B. Missing a dead family.

C. Watching a horror movie.                 D. Listening to a sweet song.

The purpose of the passage is_________.

A. to explain why people will die of a heart attack

B. to offer some advice on protecting us from heart failure

C. to compare different kinds of feelings to cause a death

D. to show strong emotions can cause a sudden death
