Early people had very little effect on the environment. They lived in caves in very small ‘clan’groups. They collected or killed only enough for the clan’s survival. Early clans were nomadic, which means that they did not stay in one place. Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to protect the environment. The land had time to recover and animals had time to breed (繁殖) before the clan returned for the next season.
As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually , people tamed(驯养) wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.
Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so they began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.
People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also gave people more free time. So art, dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.
Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.
However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.
64. Early tribes didn't have much effect on animal population because __         .
A. they kept animals for themselves              B. they ate only vegetables
C. they killed only enough for food                     D. they loved animals
65. The main purpose for small clans to join together was           .
A. to hunt animals    B. to seek safety       C. to share caves         D. to protect environment
66. Which of the following is TRUE according to this passage?
A. Early people moved to new places looking for new sources of food.
B. Modem civilization began when people started to live together in big groups.
C. Modem advancements are always good for the environment.
D. People began to exchange goods because they didn't have enough money.
67. It can be concluded from the passage that          .
A. human progress has brought civilization to the society
B. civilization has improved traditional forms of work
C. our environment has been affected by human progress
D. early people understood environmental protection

　　Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.
　　Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
　　The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.
51．Plants will emit an increased amount of heat when they are______________.
A. sprayed with pesticides　　
B. facing an infrared scanner
C. in poor physical condition　　
D. exposed to excessive sun rays
52．In order to apply pesticide spraying precisely, we can use infrared scanning to____________.
A. estimate the damage to the crops　　
B. measure the size of the affected area
C. draw a color-coded map　　
D. locate the problem area
53．Farmers can save a considerable amount of pesticide by______________.
A. resorting to spot-spraying　　
B. consulting infrared scanning experts
C. transforming poisoned rain　　
D. detecting crop problems at an early stage
54．The application of infrared scanning technology to agriculture met with some difficulties
_______________.
A. the lack of official support　　
B. its high cost
C. the lack of financial support　
D. its failure to help increase production
55．Infrared scanning technology may be brought back into operation because of_____________.
　　A. the desire of farmers to improve the quality of their produce
　　B. growing concern about the excessive use of pesticides on crops
　　C. the forceful promotion by the Department of Agriculture
　　D. full support from agricultural experts

Turning on the TV, a wonderful scene comes to your eyes — a group of men, tall, strong and handsome, and women, young, beautiful and attractive, too. Together they eat in the finest restaurants, traveling everywhere around the world by luxurious planes and pleasure ships. They are models.
Do you envy them? What sort of life are models leading? Is it a wonderful life for a young lady or a young man?
A few models are well-known actors or actresses who can make a lot of money only by showing themselves off in commercials. But the majority of them are just curious to see what it is like. They’d like to be models just because they are attracted by what they imagine — models earn a lot of money and lead a glorious life. This is true for those who are very successful. However, most models find it difficult to get work. Very few can earn enough to live on, and for all models their expenses are high. Their agents claim about 20% of the earnings, and no model will get very far without a clever agent. Besides, they have to buy good clothing. They also have to pay to travel to interviews and reach the places where the work is to be done.
Interviews for a model job are known as cattle-markets in the modeling world, and not without a good reason. A top model can choose his or her work, demand and receive high fees and has his or her expenses paid. But for most models, the situation is quite different. And agent or employer inspects each model much as a farmer inspects cattle at a market. Intelligence, qualifications and personal characteristics count for little against good looks and tight figures. For all except the very few lucky ones, the life of a model is a continual search for work, trying to sell himself or herself in the face of fierce competition and, sometimes, not particularly moral standards on the part of some employers.
Immigration officials at airport look suspiciously at a girl whose passport shows her occupation as “Model”, and these are men and women of considerable experience of the world. It comes no surprise to find that some models prefer to put “Secretary” or “Businessman” as their jobs in their passports.
Modeling is a changeable world with great rewards for a tiny minority but not for the majority.
46. For models, their good looks and tight figures are _____________, compared with their intelligence and qualifications.
A. more important              B. less needed
C. less essential               D. more looked down upon
47. Which of the following can lead you to believe according to the passage?
A. A model’s traveling expenses are usually paid by his employer.
B. To be a model, good looks are the most important qualification.
C. Most models have a fairly easy way of life with high pay.
D. A model can hardly be successful without a good agent.
48. Models often put “Secretary” or “Businessman” instead of “Model” in their passports because __________________.
A. they want to avoid being stopped to sign their names by fans
B. a person with the occupation of a model is easily attacked by black societies
C. models are sometimes looked down upon
D. secretaries and businessmen are free of custom duty
49. What may be the author’s attitude towards modeling?
A. It is a worthwhile life for a young lady or a young man.
B. He is in favor of young people to try modeling.
C. Before being crazy about a model job, young people should be aware of the difficulties.
D. It is a field in which everyone has a great chance to succeed.
50. The underlined word “suspiciously” can most probably be replaced by _________________.
A. doubtfully       B. excitedly        C. proudly         D. sadly

第一节　阅读理解（共15小题；每小题2分，满分30分）
阅读下面短文，掌握其大意，然后从41~55各题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卷上将该项涂黑。
People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem.
First the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle.
Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific.
Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully.
After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels.
Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels.
Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short , he has solved the problem.
41. What is the best title for this passage?
A. Six Stages for Repairing Sam’s Bicycle
B. Possible Ways to Problem-solving
C. Necessities of Problem Analysis
D. Suggestions for Analyzing a Problem
42. In analyzing a problem we should do all the following except .
A. recognize and define the problem
B. look for information to make the problem clearer
C. have suggestions for a possible solution
D. find a solution by trial or mistake
43. By referring to Sam’s broken bicycle, the author intends to _________.
A. illustrate the ways to repair his bicycle
B. discuss the problems of his bicycle
C. tell us how to solve a problem
D. show us how to analyze a problem
44. Which of the following is NOT true?
A. People do not analyze the problem they meet.
B. People often accept the opinions or ideas of other people.
C. People may learn from their past experience.
D. People can not solve some problems they meet.
45. As used in the last sentence, the phrase “in short” means _________.

阅读下列短文, 从每题所给的A、B、C和D项中, 选出最佳选项, 并在答题卡上将该项涂黑。
I sit at my kitchen table, while my daughter, Anna, sits next to my mother. On the wall hangs a photo of my father.
“When is Rick going to be here?” My mother asks, referring to my husband.
“I don’t know, Mom,” I answer patiently. “He’ll be here for dinner.”
I sigh and get up from the table. This is at least the tenth time she has asked that question.
While my mother and daughter play, I busy myself making a salad.
“Don't put in any onions,” Mom says. “You know how Daddy hates onion.”
“Yes, Mom,” I answer.
I scrub(洗擦) off a carrot and chop it into bite-size pieces.
“Don't put any onions in the salad,” she reminds me. “You know how Daddy hates onion.”
This time I can’t answer.
My mother had been beautiful. She still is. In fact, my mother is still everything she has
been, just a bit forgetful.
I cut off the end of the cucumber and rub it to take away the bitterness. Cut and rub. This is a trick I have learned from my mother, along with a trillion other things: cooking, sewing,
dating, laughing, thinking. I learned how to grow up.
And I learned that when my mother was around, I never had to be afraid. So why am I afraid now?
I study my mother's hands. Her nails are no longer a bright red, but painted a light pink.。Almost no color at all. And as I stare at them, I realize I am feeling them as they shaped my
youth. Hands that packed a thousand lunches and wiped a million tears off my cheeks.
Now my hands have grown into those of my mother's. Hands that have cooked uneaten
meals, held my own daughter's frightened fingers on the first day of school and dried tears
off her face.
I grow lighthearted. I can feel my mother kiss me goodnight, check to see if the window is
locked, then blow another kiss from the doorway. Then I am my mother, blowing that same
kiss to Anna.
Outside everything is still. Shadows fall among the trees, shaped like pieces of a puzzle.
Someday my daughter will be standing in my place, and I will rest where my mother now sits.
Will I remember then how it felt to be both mother and daughter? Will I ask the same
question too many times?
I walk over and sit down between my mother and her granddaughter.
“Where is Rick?” my mother asks, resting her hand on the table next to mine. And in that
instant I know she remembers. She may repeat herself a little too much. But she remembers.
“He’ll be here,” I answer with a smile.

We all have ideas about what kinds of foods are good to eat. We also have ideas about what kinds of foods are bad to eat. As a result, people from one culture often think the foods that people from another culture eat are nauseating(令人作呕的). When the famous boxer Muhammad Ali visited Africa, for example, one member of his group became quite sick when he saw someone pick up a butterfly and eat it. Many people would find it disgusting to eat rats, but there are forty-two different cultures whose people regard rats as appropriate food.
Food likes and dislikes do not always seem related to nutrition. For example, broccoli is first on a list of the most nutritious common vegetables, but it is twenty-first on a list of vegetables that Americans like most to eat. Tomatoes are sixteenth on the list of most nutritious vegetables, but they are first on the list of vegetables that Americans like most to eat.
But dislike is not the only reason why some cultures will not eat a certain food. In some cultures, certain foods are taboo. Some foods are taboo in certain religions, but there are also other food taboos that are not connected to a religion. We do not usually think about why certain things are taboo in our culture. We may not even know why they are taboo. Anthropologists(人类学家) try to discover the hidden reasons for taboos.
Anthropologists believe that most food likes and dislikes are a result of the ways of life of different people. Some people live in areas where there are both large animals and many insects. It is difficult for these people to kill large animals, and it requires a lot of energy. It is easier for them to use insects for food because it is not difficult to catch insects and it does not require a lot of energy. Nomadic(游牧的) people who move around will not want to keep pigs for food. People will not eat pets such as dogs. Americans eat a lot of beef because there is plenty of land for raising cattle and the meat can be shipped cheaply for long distances by railroads.
61.   What’s the main topic of this passage?
A. Food and religion.           B. Food and culture.
C. Nutrition of different foods.       D. Different ways of life.
62.   Which of the following statements is TRUE about food likes and dislikes?
A. They are seldom related to nutrition.
B. They are mostly associated with people’s taste.
C. They are mostly connected with people’s life styles.
D. They are usually related to cultures or religions.
63.   The underlined word “taboo” (Line 3, Para. 3) refers to _____.
A. something undiscovered    B. certain religions
C. something forbidden D. certain foods
64. What can we infer from the passage?
A. It is believed that brcoccoli is more nutritious than tomatoes.
B. Americans prefer tomatoes to beef.
C. People in Inner Mongolia would probably like to keep pigs for food.
D. The famous boxer Muhamm Ali would like to eat rat rather than butterfly.
65.   Why do Americans prefer to eat beef?
A. Because beef provides a lot of energy people require.
B. Because beef is on the list of the most nutritious foods.
C. Because they have the ideal condition to keep and ship cattle.
D. Because cattle are large animals.
