【题目】Barack Obama, Lady Gaga and Steve Jobs—what do they have in common? They are, of course, all Americans. And according to a survey by social networking site badoo. com, they all best illustrate(举例说明) the word “cool”.

But just what does it mean to say someone is “cool”? Most would answer that it is something to do with being independent-minded and not following the crowd.

Yale University art professor Robert Farris Thompson says that the term “cool” goes back to 15th century West African philosophy(哲学). “Cool” relates to ideas of grace(优雅) under pressure.

“In Africa, ” he writes, “coolness is a positive quality which combines calmness, silence, and life. ”

The modern idea of “cool” developed largely in the US in the period after World War Ⅱ. “Post-war ‘cool’ was in part an expression of war-weariness (厌战情绪) . . . it went against the strict social rules of the time, ” write sociologists Dick Pountain and David Robins in Cool Rules: Anatomy of an Attitude.

But it was the American actor James Dean who became the symbol for “cool” in the hugely successful 1955 movie Rebel without a Cause. Dean plays a tough guy who disobeys his parents and the authorities(权威). He always gets the girl, smokes cigarettes, wears a leather jacket and beats up bullies(欺凌弱小者). In the movie, Dean showed what “cool” would mean to American young people for the next 60 years.

Today the focus of “cool” has changed to athletics (体育运动) stars. Often in movies about schools, students gain popularity on th athletics field more than in the classroom. This can be seen quite clearly in movies like Varsity Blues and John Tucker Must Die.

But many teenagers also think being smart is cool. Chess and other thinking games have been becoming more popular in schools.

“Call it the Harry Potterization of America —a time when being smart is the new cool, ” writes journalist Joe Sunnen.

【题目】A

Amyotrophic lateral sclerosis(ALS) （肌萎缩性侧索硬化症） is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary(随意的) muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.

A-myo-trophic comes from the Greek language. "A" means no or negative. "Myo" refers to muscle, and "Trophic" means nourishment--"No muscle nourishment." When a muscle has no nourishment, it "atrophies" or wastes away. "Lateral" identifies the areas in a person's spinal cord where portions of the nerve cells that signal and control the muscles are located. As this area degenerates it leads to scarring or hardening ("sclerosis") in the region.

As motor neurons degenerate, they can no longer send impulses to the muscle fibers that normally result in muscle movement. Early symptoms of ALS often include increasing muscle weakness, especially involving the arms and legs, speech, swallowing or breathing. When muscles no longer receive the messages from the motor neurons that they require to function, the muscles begin to atrophy (become smaller). Limbs begin to look "thinner" as muscle tissue atrophies.

What Types of Nerves Make Your Body Work Properly?

The body has many kinds of nerves. There are those involved in the process of thinking, memory, and of detecting sensations (such as hot/cold, sharp/dull), and others for vision, hearing, and other bodily functions. The nerves that are affected when you have ALS are the motor neurons that provide voluntary movements and muscle power. Examples of voluntary movements are your making the effort to reach for the phone or step off a curb; these actions are controlled by the muscles in the arms and legs.

The heart and the digestive system are also made of muscle but a different kind, and their movements are not under voluntary control. When your heart beats or a meal is digested, it all happens automatically. Therefore, the heart and digestive system are not involved in ALS. Breathing also may seem to be involuntary. Remember, though, while you cannot stop your heart, you can hold your breath-so be aware that ALS may eventually have an impact on breathing.

Although the cause of ALS is not completely understood, the recent years have brought a wealth of new scientific understanding regarding the physiology of this disease.

While there is not a cure or treatment today that halts or reverses ALS, there is one FDA approved drug, riluzole, that modestly slows the progression of ALS as well as several other drugs in clinical trials that hold promise.

Importantly, there are significant devices and therapies that can manage the symptoms of ALS that help people maintain as much independence as possible and prolong survival. It is important to remember that ALS is a quite variable disease; no two people will have the same journey or experiences. There are medically documented cases of people in whom ALS ‘burns out,’ stops progressing or progresses at a very slow rate.

【题目】Nuclear energy has always been controversial. But since the tsunami and nuclear disaster in Fukushima (Japan) last year the issue is back in the headlines. And the world is divided— some countries are planning more nuclear plants, while others have promised to shut theirs down.

After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy are also phasing out nuclear power. But France and the United States remain staunch supporters of atomic energy. In fact, almost 80% of France’s electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan.”

Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power doesn’t create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain’s chief scientific adviser (John Beddington) supports this view. He recently said that the world doesn’t have the luxury of ignoring nuclear energy.

Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they’re expensive; and right now, they require a lot of investment. This higher cost of using “green energy” is usually passed onto the consumer. So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills. This is of particular concern while the world economy is in such bad shape.

The main argument against nuclear energy is that it isn’t safe. For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands.

The nuclear energy issue is very complex. And it doesn’t look like it’ll be resolved anytime soon. As a Japanese commentator recently said, “it’s been a bad year for the ‘nuclear village’, but I don’t think they’re down and out yet.” The battle continues.

【1】Which of the following may NOT be the advantage of nuclear energy over other energy sources?

A. Nuclear energy doesn’t produce any greenhouse gases.

B. Nuclear energy can help prevent the climate damage.

C. Nuclear energy is more environmental-friendly than other green energy sources.

D. Nuclear energy can save the consumers some money, compared to other renewable energies.

【2】What does the underlined word “this ” refer to in paragraph 4?

A. The fact that many people prefer to use the green energy sources while unwilling to pay higher bill.

B. The cost of using renewable sources

C. The fact that the nuclear power is cheaper.

D. The investment of renewable energy sources

【3】In the 5th paragraph, the author takes the case of Chernobyl disaster in Ukraine to _______.

A. convince the reader that nuclear waste is difficult to get rid of.

B. explain that nuclear waste may remain harmful to humans for thousands of years.

C. persuade the world not to use nuclear energy.

D. support the idea that nuclear energy is not safe.

【4】We can learn from the last paragraph that _______.

A. the Japanese commentator is positive about the future of nuclear energy.

B. the nuclear energy issue will be soon settled.

C. a battle will break out in the future.

D. Japan is considering to build a nuclear village in the future.

【5】What is the author's purpose of writing the passage?

A. To highlight the danger of using nuclear energy.

B. To introduce some serious nuclear disasters.

C. To show the argument between nuclear supporters and protesters.

D. To give some advice on how to use nuclear energy safely.

【题目】For some people, music is no fun at all. About four percent of the population is what scientists call “amusic.” People who are amusic are born without the ability to recognize or reproduce musical notes(音调). Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are very far apart on the musical scale.

As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their inability to enjoy music set them apart from others. It can be difficult for other people to identify(识别) with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics have to stay away from places where there is music. However, this can result in withdrawal and social loneliness. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.

Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it is not connected with defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can’t see certain colors.

Many amusics are happy when their condition is finally diagnosed (诊断). For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. “When people invite me to a concert, I just say, ‘No thanks, I’m amusic,’” says Margaret. “I just wish I had learned to say that when I was seventeen and not seventy.”

【1】Which of the following is true of amusics?

A. Listening to music is far from enjoyable for them.

B. They love places where they are likely to hear music.

C. They can easily tell two different songs apart.

D. Their situation is well understood by musicians.

【2】How did scientists learn to identify amusics?

A. By studying different kinds of music.

B. By going to parties regularly.

C. By studying amusic people.

D. By comparing music to color.

【3】According to paragraph 3, a person with “defective hearing” is probably one who ______.

A. dislikes listening to speeches

B. can hear anything nonmusical

C. has a hearing problem

D. lacks a complex hearing system

【4】In the last paragraph, Margaret expressed her wish that ______.

A. her problem with music had been diagnosed earlier

B. she were seventeen years old rather than seventy

C. her problem could be easily explained

D. she were able to meet other amusics

【5】What is the passage mainly concerned with?

A. Amusics’ strange behaviours.

B. Some people’s inability to enjoy music.

C. Musical talent and brain structure.

D. Identification and treatment of amusic
