Sharks have lived in the world's oceans for millions of years. A shark has an extremely good sense of smell. It can find small amounts of substances in the water, such as blood, body liquids and chemicals produced by animals. These powerful senses help them find their food.   51 

Sharks grow slowly. About forty percent of the different kinds of sharks lay eggs.   52   Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal.

  53  .They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in the ocean do not become too great. This protects the plants and other forms of life that exist in the oceans.

People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased greatly because many parts of a shark are valuable. 54  Shark liver oil is a popular source of Vitamin. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins.

Sharks are among the oldest animals on Earth.   55   If too many sharks in one area are killed, the group of shark may never return to normal population levels.

A. The others give birth to live young.

B. Sharks are important for the health of the world's oceans.

C. This is a threat to other form of life in the ocean.

D. Collectors pay thousands of dollars for the jaws of a shark.

E. Sharks are valuable to us and we can make full use of them.

F. But some sharks are in danger of disappearing from Earth.

G. Sharks eat fish, other sharks, and plants that live in the ocean

   In American crime movies, policemen search crime scenes for anything that might belong to a criminal— bits of fingernail , blood or hair— in order to find out who they are. What they hope to find is the key to their identity—their DNA.

DNA is the chemical that contains a person’s genetic makeup. Every person, except for identical twins, has unique DNA information. That is why we can use it to identify someone.

There is no doubt that DNA evidence is becoming a very powerful tool for law enforcement (实施)officers. In the US, all 50 states and the federal government keep DNA databases of some criminals after they have been convicted（宣告有罪）. Whenever a crime happens, the police collect DNA from the crime scene and compare this with samples they already have in the criminal database. If they match any suspect in the database, then they’ve caught their criminal. Even if they don’t, the DNA sample can still be used to determine the person’s sex, height, hair and eye color and other characteristics. This helps police to create a physical profile of the criminal.

Some people feel that the database should be made bigger to contain everyone’s DNA and help to solve many more crimes. This would also avoid mistakes when someone is wrongly convicted of a crime. DNA doesn’t make mistakes.

However, other people are worried that it would violate their privacy. Someone’s DNA can be used to gather information such as the person’s family and ethnic（种族的） background, whether he or she has a gene mutation（突变）or certain genetic diseases, and other personal issues. People are afraid that this information might be used inappropriately. They may fear that employers might read it and treat them differently. People may also be afraid that personal data might get into the hands of insurance firms or loan companies. For example, if they knew from your DNA that you had a genetic risk of a serious disease, they might be able to refuse you life insurance, a loan, or even a job.

Clearly, the use of DNA evidence will continue to help the police solve crimes. However, social and ethical concerns about DNA will also remain a topic of debate.

47. What is the article mainly about?

A. The possibilities opened up by DNA technology     B. The controversy over DNA databases

C. How DNA databases are built                    D. What role DNA plays in solving crimes.

49. Some people suggest building a database containing everyone’s DNA because _____.

A. it would mean fewer people commit crimes.

B. it would make it more convenient for the government to gather information

C. it would help the police identify suspects more efficiently and accurately

D. such a database could be helpful in many more fields besides solving crimes

50. What is the great concern over the DNA database according to the article?

A. Some people might make use of it to make money.

B. It would threaten people’s individual privacy and rights.

C. The DNA stored in the database might be labeled wrongly.

D.The DNA would have a gene mutation and become inaccurate.

   Statuses are wonderful human inventions that enable us to get along with one another and to determine where we "fit" in society. In our everyday lives whenever we meet people, we always try to judge them in terms of their statuses. For example, we must judge whether the person in the library is a reader or a librarian, whether the telephone caller is a friend or a salesman and so on.

  Our statuses often vary with the people we meet, and change through life. Most of us can, at very high speed, assume(表现出) the different statuses that various situations require. Much of social communication consists of recognizing and selecting among proper statuses and allowing other people to assume their statuses in relation to us. This means that we fit our actions to those of other people, based on a constant mental process of assessment and understanding. Although some of us find the task more difficult than others, most of us perform it rather easily.

A status has been compared to ready-made clothes. Within certain limits the buyer can choose style and material. But an American is not free to choose the clothes of a Chinese peasant or that of a Hindu prince. We must choose from among the clothing presented by our society.

Furthermore, our choice is limited to a size that will fit, as well as by our wallet. Having made a choice within these limits, we can have certain changes made. But apart from small adjustments, we tend to be limited to what the stores have on their shelves. Statuses too come ready-made, and the range of choice among them is limited.

44. According to the writer, people often assume different  statuses______.

A. in order to distinguish themselves from others       B. in order to better recognize other people

C. as their mental processes change                  D. as the situation changes

45. In the last sentence of the second paragraph, “it” refers to “___”

A. constant mental process                        B. selecting one’s own statuses

C. recognition of other people’s statuses              D. fitting our actions to those of other properly

46. What can be the best title for this text?

A. Proper Relations.   B. Limited Choices.    C. Judgment of Statuses.   D. Comparison of Clothes.

    A warm blanket is the ideal sleep aid for a freezing winter night. The right blanket can warm your bones but the wrong one can affect your sleep. I asked experts for advice on picking the perfect blanket for a good night’s sleep. Here’s what they told me.

     When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. “People seem to sleep best at temperature between 62 and 70 degrees F,” says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can rouse you from sleep. A good blanket helps drive the coldness away.

     At the other extreme, overheating yourself can affect your sleep as well. “Core body temperature typically drops during the first four hour’s of sleep,” says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep.

     “In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control,” says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe.” This is the reason why many people like to sleep under a blanket even in summer.

     “If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults,” Moor says. She adds that weighted blankets are not recommended for those recovering from surgery.

     “People can also have serious preferences for a particular blanket,” says Dr. Hoagland. “Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker.” In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily.

40. The author wrote the passage mainly to tell us _____.

   A. the importance of blankets                   B. how to choose the perfect blanket

   C. different materials used to make blankets        D. the history and usage of blankets

41. The underlined word “rouse” in Paragraph 2 is the closest in meaning to “______”.

   A. wake up     B. take up     C. make up     D. pick up

42. What do we know from the passage?

   A. Body temperature rises when we fall asleep

   B. The perfect sleep temperature should be above 70 degrees F.

   C. Weighted blankets should be at least 30 pounds.

   D. People are advised to use their own blankets.
