A new study shows one of the largest glaciers① in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.

The rates② of change that we’re noticing are much higher than expected. If these rates continue, it is not unlikely that Greenland could shrink③ by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.

Greenland is the world’s largest island, covering an area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.

Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past four years, its trip to the sea has sped up from about 70 feet per day to nearly 110.

The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit in the last decade. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen anytime soon.

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. 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.

3.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.

4. 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

【小题1】The underlined sentence in the first paragraph implies that _____．

Why does the rate of heart attacks increase during the World Cup football finals? How can we help an overweight patient to lose weight? They’re just some of the topics covered in a new book by University of Sussex academics, which is helping student doctors to consider the importance of psychology in medical practice.

Psychology for Medicine is the first textbook of its kind, providing medical trainees and new doctors with all the relevant psychological knowledge they need. Previously, students had to refer to many different books for the relevant psychology.

The book, by Sussex psychologists Dr. Sussex Ayers and Dr. Richard de Visser, has been well received by fellow academics and medical doctors and was finished with the help of the students and staff of the Brighton and Sussex Medical School. The students proofread（校对） the chapters, provided ideas for the content and even modeled for the photographs. The book provides a solid grounding in psychological study relevant to medicine, along with practical tips and advice for practice. One student, Simon Hall, drew cartoons for the book.

The study psychology is important for doctors for a number of reasons. Psychological and physical symptoms are highly related. Up to a third of patients will have psychological disorders, while physical causes are usually only found in around 15 per cent of people’s symptoms. In treatment, a lot of the effect drugs can be due to patients believing they will recover rather than the drug itself.

Dr. Ayers says, “The important thing about this book is that it’s applied science --- it shows why psychology is important to medicine and how we should use it. The book’s presentation is really important. It’s not just lots of theory, but full of tips and advice so that students can take what they learn in the classroom and apply it to real-life situations.”
