Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his new place and meet his friends.
My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him. He seemed unhappy with me unless I got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.
On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor café. We talked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical (挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?
The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in doing so, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.

A study of a university in Shanghai had found that many of the students there are using a quote(引语)from the Italian poet Dante as a kind of motto. The study of Fudan University, one of China’s top universities, of 489 students, found that 82 had chosen Dante’s “Follow your own path and don’t worry about what others say” as their motto, out of 278 people who said they had a motto. This was followed by “Believe yourself” and “Self-improvement without stop.”
Students also expressed a common hope for greater understanding and care and said they were always ready to give a hand to those in need. Some researchers think that mottoes can play an important part in children’s growth and they say that a good motto can help children develop a better character.

In 1789 the U.S. government passed a law which said that the land of the American Indians could never be taken from them without their agieement. One hundred years later, however, the Indians only had a very small part of the land that originally belonged to them. How did this great
Injustice(不公正) occur?
After 1812 white settlers began to move west across North America. At first, the settlers and the Indians lived in peace. However, the number of settlers increased greatly every year. and slowly the Indians began to see the white settlers as a danger to their survival. To feed themselves, the settlers killed more and more wild animals. the Indians, who depended on these animals for food, had to struggle against starvation. The settlers also brought with them many diseases which were common in white society. but which were new for the Indians. Great numbers of Indians became sick and died.Between 1843 and 1854 the Indian population in one area of the country went down from 100,000 to30,000.
More land was needed for the increasing number of white settlers. In Washington, the old respect for the rights of the Indians disappeared. The old promises to the Indians were broken; the government began to move groups of Indians fiom their original homelands to other poorer parts of
the country. Some Indians reacted angrily and violently to this treatment. They began to attack white settlers, and the Indian war began. For 30 years, until the late 1880s, different groups of Indians fought against the injustices of the white mari. They had a few famous successes, but the result of the siruggle was never in doubt. There were too many white soldiers, and they were too powerful. Many Indians were killed; the survivors were moved from their homelands to different areas of the country.It was a terrible chapter in the history of a country that promised freedom and equality to everyone.

Many disease researchers have warned that rising global temperatures could lead to more diseases. for example by allowing tropical diseases to expand their ranges into what are now mild regions. This is a particular fear for the diseases carried by insects such as malariac(疟疾) and
sleeping sickness.
But the reality is more complex, argues Kevin Lafferty. a disease ecologist. He argues that a warming climate could favour some diseases in certain regions while controlling them in others.
Lafferty does not deny that climate change might allow malarial mosquitoes to spread to new areas. However he believes that hotter and drier conditions may also get rid of mosquitoes from areas where they currently exist. If this were the case, he says. there would be little. if any, net
increase (净增长) in the risk of disease.
In addition, many mild regions such as southern Europe or the southern U.S. have good sanitation(卫生设备) and insect control programmes which, Lafferty says, would prevent diseases from becoming common even if climatic conditions were suitable.
Finally, he argues, climate change could wipe many species off the plant. Infectious pathogens(病原体) depend on their hosts for survival so they too may become endangered-especially if they,like malaria, rely on more than one host.
But Mercedes Pascual of the University of Michigan points out that there are large human populations in the east African highlands, just outside of the existing range of malarial mosquitoes.She said as temperatures rise, the mosquitoes will reach these areas. So the disadvantages will
outweigh the advantages of decreased risk elsewhere.
Most of the ecologists do, however, seem to agree on one point: predicting where a disease is going to go next involves far more than just considering climate. No matter what the results of the debate are, they all agree that health concerns should continue to play a critical role in climate policy and the debate shouldn't be regarded as weakening the case for action against global warming.
53. According to Kevin Lafferty, climate change__________
A. will not increase the spread of insect-bome diseases
B. may not significantly increase the risk of disease in the whole world
C. will not affect the dry regions where sanitation is good
D. may not affect viruses that depend on more than one host
54. What does Mercedes Pascual think of Lafferty 's conclusion?
A. She disagrees with it. B. She supports it.
C. She is not sure ofit. D. She thinks it needs proving.
55. We may infer from the passage that ___________
A. climate is the only factor in the predictior of the spread of diseases
B. when making a climate policy one should take health into account
C. the debate mentioned in the passage furthers the debate on global warming
D. a policy should be made immediately to try to stop climate change
56. We can learn from the passage that ___________
A. all the disease researchers agree that climate change will spread disease
B. nothing can be done to stop the present global warming
C. scientists have found ways to stop the wild spread of disease
D. ecologists have different views on whether the global warming will spread diseases further

C
Throughout the world, clothing has many uses. It is used to provide protection from the elements. It is also worn to prevent others from seeing specific parts of one's body. However, the parts of the body that must be covered vary widely throughout the world. Some clothing is worn to
provide supernatural protection. Wearing a lucky shirt to take an exam is calling for supernatural assistance.
People in all cultures use clothing and other forms of bodily decoration to communicate status,intentions and other messages. In North America, we dress differently for business and various leisure activities. North American women usually are much more knowledgeable of and concerned
With little difference in messages communicated by clothes than men. At times, this leads to silly mistakes of interpretation(解释) of female intentions on the part of men. Of course. clothing styles also are intended to communicate messages to members of the same gender(性别).
Long before we are near enouth to talk to someone, their appearance tells their gender, age,economic class. and often even intentions. We begin to recognize the important cultural clues at an early age. The vocabulary of dress that we learn includes not only items of clothing but also
hairstyles, jewelry, and other body decoration. In most cultures, however, the same style of dress communicates different messages depending on the age, gender. and physical appearance of the individual wearing it.
Putting on certain types of clothing can change your behavior and the behavior of others towards you. This can be the case with a doctor's white lab coat, or an army uniform. Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status. For instance. the
strange hairstyle and clothing of the English "punks" are essential aspects of their uniforms.
There are many forms of body decoration other than clothes that are used around the world to send messages. These include body and hair paint, and even body deformation. When doctors put braces on teeth, they are actually doing the same thing - deforming or reforming a part of the body
to make it more attractive.
49. What is the passage mainly about?
A. Clothing and Culture B. Communication through Clothing
C. Clothing and Social Behavior D. Ways of Sending Messages
50. In North America men sometimes misunderstand women's intention because
A. men are more careless than women
B. women spend more time on their clothes
