Many animals recognize their food because they see it. So do         . When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other          when you choose your food. You may          it because it smells good or because it          good. You may dislike some types of food because they do not look, smell or taste very nice.

Different          use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many          types of food, some animals spend their lives eating only one type. The giant panda eats only one         type of bamboo. Other animals eat only one type of food even when given the       . A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other         in the garden. However, most animals have a more          diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The          of these animals will be different depending on the season.

        have a very varied diet. We often eat food because we like it and not because it is       for us. In countries such as France and Britain, people eat foods with too much         . This makes them overweight, which is bad for their health. Eating too much red meat and animal         , such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modem life.

Ban Fur? Then Why Not Leather?

    Much to the displeasure of some local businesses, the City Council in West Hollywood, California, voted without opposition last week to ban the sale of fur products. Should laws be involved in this issue? Is it unfair to ban sales of fur, but not sales of leather and hides (兽皮)?

    Animals Do Not Have Rights

    By Tibor R. Machan

    My view is that animals do not have basic rights. It is a matter of ethics (伦理学) and not of the laws of human societies. If animals had such rights as human beings do, they would have to be held responsible for killing fellow animals in the wild. That way of thinking about animals makes a category mistake. Using animals, including their fur or organs, to improve people's lives is acceptable.

    A Small Step Against Cruelty

    By Kate Carter

    Both fur and leather are the skins of dead animals. Why should we think that the lovable furry ones deserve more of a life than the less pleasing ones? Some say leather is  less cruel because it's a byproduct (副产品) of the meat industry. But this isn't really true. Some cheap leather may be a byproduct of the meat industry, but often it's the other way round. In South Africa, where there is a developing market for ostrich(鸵鸟)farms, the skins account for roughly 80 percent of the slaughtered (宰杀)birds' value, a mere 20 percent of which comes from the meat.

    "Who" Are You Wearing?

    By Marc Bekoff

    West Hollywood's ban is a move in the right direction. However, we must work to ban the sales of leather and hides, too. Furs come from animals who are attacked to become clothing, while some leather and hides come from slaughterhouse(屠宰场) animals. We must remember that when people choose to wear fur, leather and hides, they are wearing formering conscious beings. So it's a matter of who they are wearing, not what they are wearing because these animals must be referred to as who and not what or that.

1.What is the passage mainly about?

    A. West Hollywood's ban on fur products.

    B. Differences between fur and leather sales.

    C. The government's role in protecting animals.

    D. The ecological imbalance in West Hollywood.

2.Tibor R. Machan seems to believe that          .

A. laws should be passed to protect animals

B. humans are respornsible for killing animals

C. it is not reasonable to use animals to improve life

D. animals and humans aren't supposed to share equal rights

3.What is Kate Carter's opinion about wearing fur and wearing leather?

A. Both are decided by the meat industry.

B. There is little distinction (区别) between them.

C. Wearing fur is generally more acceptable.

D. Wearing leather is cheaper than wearing fur.

4.What is Marc Bekoff’s attitude towards sales of fur?

A. Sympathetic.       B. Careless.         C. Tolerant.         D. Opposed.

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.

    In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.

    It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.

C. much needs to be done before humans can have a longer life

D. we have already solved the technical problems in building new cells.

A Charlotte N.C. man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. 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—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, which was originally described by Walter Cannon，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 automatic 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 early 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 poisonous 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.

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 excitement 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.

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

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

2.What can we learn about the fight-or-flight response according to the passage?

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

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

C. The ancient humans had a better 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 an unexpected fortune.

B. Missing a dead family member.

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

How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.

What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.

Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.

A CAT scanner, however, uses a group of X rays to give a cross-sectional（横截面）view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.

Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.

CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.

What is NOT true of a CAT scan?

A．It is safer than regular X rays.

B．It makes use of computer techniques.

C．It can stop the action of an organ for a short time.

D．It gives clear pictures of active, moving body parts.

The underlined words “a foreign object”（Para 3）most probably refer to      .

A．a badly injured part inside the body

B．a new thing that is unknown to the doctor

C．a strange organ that has grown in the body

D．an object that gets inside the body by chance

What is the special use of the latest CAT scanners?

A．It provides clear photos of moving organs.

B．It can take 3-dimension（三维）pictures of inside organs.

C．It won’t cause serious skin burns, cancer or other damage to the body.

D．It helps to find out what is going on inside a person’s body without opening it up.

We can infer from this passage that      .

A．patients in front of CAT may suffer from a bit of radiation

B．doctors need no opening-up of the body with CAT scanners

C．CAT scanners are more expensive than regular X-ray machines

D．CAT scanners can take photos of either the whole body or a part of it

The best title of this passage might be        .

A．the Newest Medical Invention

B．New X-ray Machine to Save Lives

C．How to Avoid the Damage of X Rays

D．Advantages and Disadvantages of CAT Scanners
