My bookshelves are full of dust — and with good reason. When it comes to cleaning that part of my home, I suffer from the most serious case of avoidance (回避反应症).

The thing is this: when I do set out to clean and re-organize my books, which seldom happens, I place myself into a really bad situation. No sooner do I take a title from the shelf, blow off the dust, and wipe down the cover than I find myself sitting on the floor with legs crossed and my back against the wall. Pretty soon books get piled up on my legs as I am reunited with old friends.

It is as if these books have voices, and each wants to say its piece. “Remember me? I was given to you when you went into the Navy, so that you would never lack for companionship,” one whispers. Another says, “I was your first book of poems, given to you before you learned to love poetry.” And a third, “I was the book that made history so attractive to you.”

Perhaps the greatest pleasure of re-organizing my books are the surprises — or better said, reunions — that occur. During my latest book-cleaning adventure, I found one that had fallen behind the shelf: “Tales of Edgar Allan Poe.” Not an unusual title, but the words written on the first page made it very special: “With Love from Mom and Dad, Christmas 1965.” What’s this? A book on the physics of lasers(激光). It is filled with mathematical statements, and I had bought it at a library sale when I was 12, not long after the laser had been invented. I couldn’t understand a bit of it, but I did learn what “laser” meant.

What I end up with when I empty my bookshelves is a cross-section (横剖面) of my personal history. It’s like a road cut where one sees all the layers of rock going back through time to the beginning of the simplest life forms. The books I’ve read — and kept — are not just old friends. They are my résumé.

1.What could be said about the author?

A.He is too busy to tidy up his bookshelves.

B.He considers his books treasured possessions.

C.He has made a lot of notes in his books.

D.He is a lover of science books.

2.By saying that his books have voices, the author means ________ .

A.they bring back happy memories

B.they are recorded in human voice

C.they say a lot about human history

D.they offer good topics for discussion

3.What does the author enjoy most from re-organizing his books?

A.Finding some missing books.

B.Putting books in good order.

C.Learning something new from the books.

D.Rediscovering interesting stories behind some books.

4.The underlined word “résumé” in the last paragraph probably means ______.

A.personal history    B.precious notes      C.good companion    D.simple life forms

Mike McClure walked into Sarasota Bay for a little fishing on a beautiful day last April. This afternoon, the water was shallow enough at low tide that McClure could easily walk 100 yards offshore and cast (投) his line in any direction.

Near sunset, still without a fish, he decided to turn back. Rather than turn to his earlier course, he chose a more direct path toward shore, thinking the bay wouldn't get deeper along the way. Instead, he was trapped. He tried to walk in different directions, but shallower water eluded (避开) him. Finally, he decided his safest choice was to head straight for land.

"Within about five steps, the water was coming in through the top of the waders (高筒防水胶靴)," says McClure.

He felt the deadweight(重物) of the flooding waders pulling him down and knew that if he didn't get out of them, he would drown. But he failed to kick his way out of the waders. Instead, they pulled him completely below the surface.

Back onshore, Eliza Cameron, 19, Loren Niurka Mora, 20, and Caitlin Petro, 20, had been watching McClure fish as they rested on the grass after a long week of classes. They saw McClure go under and then heard him cry, "Help!"

The three friends kicked off their shoes and ran into the bay. They were all good swimmers, but all hid a fear that he might pull them down too because they'd have to dive to save him.

When they reached him, he'd managed to kick himself out of the waders, but his eyes had partly rolled back. Cameron and Mora each hooked (钩住) an arm under his shoulders, while Petro supported his back and held his hand. Then the three friends tried their best to tug (拉) him towards shore. Finally, they all returned to the shore safely.

Mike McClure didn't turn back by his earlier course because      .

     A. he wanted to choose a short course

     B. his earlier course was dangerous

     C. he just wanted to take a risk

     D. he knew where the water was deep

What directly trapped Mike McClure in the bay?

     A. His wrong decision.

     B. The coming high tide.

    C. His waders' being flooded.

    D. The depth of water.

During the rescue,      .

       A. the three women were afraid of being trapped in the water

       B. Cameron and Petro helped catch Mike McClure's arms

       C. the three women removed Mike McClure's waders

       D. Mike McClure still wore his flooding waders

What’s the main idea of this passage?

      A. Enjoy fishing on a beautiful day.

      B. Help others when they are in trouble.

      C.A terrible experience during fishing.

      D. How to rescue people when they’re drowning.

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
