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.

1.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.

2. What is Martin Samuels’ attitude to the possibility of being frightened to death?

A. Approval.              B. Disapproval.                  C. Doubtful.          D. Indifferent.

3.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.

4. 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.

5.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

D
COPENHAGEN—The world is gathered in Copenhagen for the U.N. climate summit, but Denmark’s bicycle-friendly capital has also given its name to a movement of cities trying to find a kinder way to travel to and from work.
Nearly 40 percent of Copenhagen’s population cycle to work or school on ubiquitous(无处不在的) paved cycle paths. Many residents take to their bikes year-round, braving rain and snow through the winter in a city where the bicycles outnumber the people.
Amsterdam and Beijing too are known for their bicycles, but the Danish capital is where urban planners from around the world have been looking for ways to get their people out of cars and up onto bikes, an effort known as Copenhagenisation.
Klaus Bondam, Copenhagen’s technical and environmental chief, calls himself a “mega cyclist” and says the bike’s popularity stems partly from high taxes on cars which meant working-class Danes could not afford to drive in the 1930s and 1940s. “Today you’ll meet everybody on the bicycle lanes — women and men, rich and poor, old and young.” Bondam said.
The local government has during the last three years invested more than 250 million crowns ($49.42 million) in bicycle lanes and to make the traffic safer for bicyclists. Today around a third of the population drive cars to work or study, another third take public transport, while 37 percent cycle -- a figure the city aims to increase to 50 percent by 2015.
There are many benefits when citizens choose bicycles over cars: pollution and noise decline, public health improves, and more people on bikes or walking creates a sense of safety in the city. Fewer parked cars leaves more space for playgrounds, parks, shopping areas and other useful public places.
53. According to the first paragraph, Copenhagen is better known as ___________.
A. a city without cars                B. a bicycle-friendly city
C. Denmark’s capital                D. the U.N. climate summit
54. We can learn from the second and the third paragraph, __________.
A. there is no path for cars during rainy and snowy days
B. citizens are limited to have only one bike for each person
C. two-thirds of people in Copenhagen cycle to work or school
D. city planners try their best to encourage more citizens to ride bikes
55. Bikes are popular in Copenhagen partly because ___________.
A. the citizens are unable to afford to buy a car
B. the rich tend to keep fit by cycling to work
C. young people regard cycling a fashion to follow
D. high taxes were paid for cars in the 1930s and 1940s
56. We can learn from the passage that __________.
A. cars are forbidden to park in Copenhagen
B. more citizens tend to choose cars in Copenhagen
C. Copenhagen becomes a model for cities’ traffic
D. living standards in Copenhagen are greatly declining

The earth's biosphere (the surface layer of the planet and the surrounding atmosphere) provides the land, air, water, and energy necessary to sustain life. This life-support system is a complex, interdependent one in which energy from the sun is changed into food for humans. The entire system depends on the sun, reasonably moderate temperature, and enough supplies of oxygen, pure water, and fertile soil.

Since the earth's creation millions of years ago, the ecosystem has worked as an interdependent system relatively undisturbed by outside forces. But recently, especially since the Industrial Revolution, human beings have begun to disturb the balance of nature. Natural resources have been severely depleted (消耗) (forests have been destroyed, fertile land worn away, water polluted, and minerals used up), and the life-support system of air, water, and land has been poisoned by a variety of waste products and chemicals.

The degree of these problems was noted in a report by the U.N. Developing Council on Environmental Quality. This report predicted that if present trends continue, the world will be more crowded and polluted and less stable ecologically and politically than the world we live in now.

The twin problems of resource shortages and pollution are caused by three social forces.  First, the tremendous increase in population growth constantly increases the demand for food, energy, and other products. As the current population continues to increase, the stress on an already overburdened environment will be increased.A second source of the problem is the concentration of people in urban areas, where the ecosystem simply cannot absorb their waste products. Finally, environmental problems are worsened as more and more nations move toward modem development: an increased reliance on modern technology. As these nations become more technological, they will consume more energy, deplete more natural resources, and create more waste products than the biosphere can absorb.

The life-support system is composed of _____.

       A.air, water and land   B.the earth, the sun and energy

       C.food, land and energy     D.food, energy and the sun

The life-support system _____.

       A.change energy from the sun into food for humans

       B.depends on the sun for enough supplies of air, water and land

       C.exists in the surface layer of the earth and the surrounding atmosphere

       D.is a complex but independent system

The life-support system has been badly damaged by _____.

       A.natural forces   B.human activities  C.social movements      D.political changes

The passage mainly talks about _____.

       A.the effects of Industrial Revolution on human beings

       B.the importance of life-support system to human beings

       C.the significance of balance of nature

       D.the destruction of life-support system and its causes
