At one time, computers were expected largely to remove the need for paper copies of documents（文件）because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organisation.
Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers
Does all this mean environmental concerns （環(huán)境問題） have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. “I guess people believe that the problem is taken care of, because of recycling （回收利用）,”said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
72.   The growing demand for paper in recent years is largely due to ___________.
A.    the rapid development of small businesses    B. the opening up of new markets
C.    the printing of high quality copies               D. the increased use of the Internet
73.   Environmentalists believe one possible way of dealing with the paper situation is ______.
A.    to encourage printing more quality documents
B.    to develop new printers using recycled paper
C.    to find new materials for making paper
D.    to plant more fast-growing trees
74.   Hewlett-Packard Co. has decided to develop new technologies because ___________.
A.    people are concerned about the environment
B.    printers in many offices are working overtime
C.    small companies need more hard copies
D.    they see a growing market for printers
75.   What would be the best title for the text?
A. Computers and Printers                                B. E-mail and the Business World
C. Internet Revolution and Environment                D. Modern Technology and New Markets

Faces, like fingerprints, are unique. Did you ever wonder how it is possible for us to recognize people? Even a skilled writer probably could not describe all the features that make one face different from another. Yet a very young child --- or even an animal, such as a pigeon --- can learn to recognize faces. We all take this ability for granted. We also tell people apart by how they behave. When we talk about someone’s personality, we mean the ways in which he or she acts, speaks, thinks and feels that make that individual different from others.
Like the human face, human personality is very complex. But describing someone’s personality in words is somewhat easier than describing his face. If you were asked to describe what a nice face looked like, you probably would have a difficult time doing so. But if you were asked to describe a nice person, you might begin to think about someone who was kind, considerate, friendly, warm, and so forth.
There are many words to describe how a person thinks, feels and acts. Gordon, an American psychologist, found nearly 18,000 English words characterizing differences in people’s behavior. And many of us use this information as a basis for describing, or typing his personality.
Bookworms, conservatives（保守派）, military（軍人或軍事的）types --- people are described with such terms. People have always tried to type each other. Actors in early Greek drama wore masks to show the audience whether they played the villain’s or the hero’s role. In fact, the words “person” and “personality” come from the Latin persona, meaning mask. Today, most television and movie actors do not wear masks. But we can easily tell the good guys from the bad guys because the two types differ in appearance as well as in actions.
6.The passage tells the readers ______.
A. how to describe people’s faces
B. how to describe people’s personality
C. how to differ good persons from bad ones
D. how to describe people both inward and outward
7. What is the possible role of the writer?
A. Psychologist     B. Behaviorist    C. Writer    D. Sociologist
8. Which of the following is incorrect?
A. Different people may have different personalities.
B. People differ from each in appearance.
C. People can describe all the features of others.
D. People can learn to recognize faces.
9. It is easier to describe a person’s personality in words than his face because ______.
A. a person’s face is more complex than his personality
B. a person’s personality is easily distinguished
C. people’s personalities are very alike
D. many words are available when people try to describe one’s personality
10. People classify a person into certain type according to ______.
A. his way of acting and thinking
B. his way of speaking and behaving
C. his learning and behavior
D. his physical appearance and his personality

Have you ever got stuck with unwanted courses or a class schedule that cannot be changed? If so, that's because you don't know how to select the perfect sch
edule. But by following a few simple steps, you can begin any term with the right courses at the most convenient times.
First, you must find the right courses. These are the ones that have the least amount of work, the fewest tests and the kindest professors. Ask your friends about courses in which they received A's after attending only 70 percent of the classes. Ask around, too, to see which instructors have given the same tests for the last fifteen years. Photocopies of these tests are usually cheap and can be easily found in school. Then, pick up a copy of the master schedule and study it carefully. Find the course titles that mean an easy pass for a painless subject.
Look for titles like “Arts and Crafts for Beginners” and “Rock Music of the 1950s”.
Next, when you have got lists of easy instructors and subjects, you can begin to select your time periods. If you stay up late in order to watch old movies, you may want a daily schedule that begins no sooner than noon. You should schedule only afternoon courses, too, if you're one of those people who hate to leave a warm bed in the morning. On the other hand, if you are a person who gets out of bed at dawn, you may want to get your classes out of the way as early as possible. That way you have the rest of the day free. Morning classes are also necessary if you are a soap opera(肥皂劇) fan.
Finally, you want your schedule to pass through registration successfully. The main way to do this is to register(注冊) early. If a course does happen to be closed because you simply couldn't register at 7:00 am, you may still be able to get in. Talk to the professor and tell him or her that a serious and hardworking student like yourself would be a shining example to other students. Be sure to carry a list of back-up courses to registration, though, just in case one of your chosen classes changes professors or time periods.
By following these suggestions, any student can pick the perfect class schedule. College can thus become an almost pleasant activity.
1.Which of the following statements is true?
A.You can get copies of tests if you are willing to pay the price.
B.“Rock Music of the 1950s” may be an easy course.
C.It is difficult to pick the perfect class schedule.
D.Attendance is required in all classes. 
2.You should  ________ .
A.register for classes in the morning if you get up early
B.have classes late in the morning if you stay up late
C.sign up for afternoon classes if you want to see soap operas 
D.choose classes in the evening if you want to watch old films 
3.If a course happens to be closed, you should  ________ .
A.register at 7:00 am               B.sit in on the class anyway
C.register for a back up course      D.get help from the professor 
4.Which of the following would be the best title for the passage?
A.Course Registration Made Easy         B.How to Find the Right Courses 
C.Classes and After?class Activities     D.How to Pick the Perfect Schedule

Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.
One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill（廢渣填埋場）, the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste. The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.
Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.
Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.
72. What would be the best title for the text?
A. Measures of Reducing Dangerous Waste
B. Danger of Harmful Waste to Mankind
C. Dangerous Waste and Water Pollution
D. Environmental Protection
73. According to the text, people       .
A. do not produce harmful waste in their daily life
B. do not know where to place the dangerous waste
C. are not clear about how serious the dangerous waste problem is
D. are not sure about where harmful waste ends
74. What troubles industries most in dealing with the dangerous waste problem?
A. How to get government support.
B. How to increase their production.
C. How to store harmful waste.
D. How to cut down the related costs.
75. What can be inferred from the passage?
A. The polluting industries are not allowed to sell their products.
B. Present technologies have settled the harmful waste problem.
C. Everyone should obey the government rules for the problem.
D. To solve the problem requires the efforts of the whole society.

Most rain forests lie close to the equator(赤道),where the climate is often mild and there are long hours of sunshine.The warmth of the land heats the air above,causing it to rise and tiny drops of water to fall as rain.The rainfall can reach at least 98 inches a year.This wet,warm world with plenty of sunlight is perfect for plants to grow,so the trees grow fast with green leaves all the year round.The trees themselves also have an effect on the climate.They gather water from the soil and pass it out into the air through their leaves.The wet air then forms clouds,which hang over the treetops like smoke.These clouds protect the forest from the daytime heat and night-time cold of nearby deserts,keeping temperatures fit for plant growth.
Rain forests slightly farther away from the equator remain just as warm,but they have a dry season of three months or more when little rain falls.Tree leaves fall during this dry season and new leaves grow when the wet season or monsoon(雨季) begins.Thus these areas are known as the “monsoon forest”.
Another type of rain forest grows on tropical mountains.It is often called the “cloud forest” because clouds often hang over the trees like fog.
The rain forest is the ideal place for the growth of many different trees.Most of them depend on animals to eat their fruits and spread their seeds.When the fruits are eaten,the seeds inside them go undamaged through animals’ stomachs and are passed out in their droppings.The seeds lying on the forest floor then grow into new trees.
小題1:The climate of the rain forests near the equator is _______.
A．mild,wet and windyB．hot,rainy and foggy
C．hot,wet and cloudyD．warm,wet and sunny
小題2:We can learn from the passage that _______.
A．tree leaves are green all the time in the monsoon forest
B．there is a dry season in the cloud forest on tropical mountains
C．clouds help the plants in the rain forest near the deserts to grow
D．the formation of climate in the rain forest has little to do with the trees
小題3:According to the passage,_______ play the most important role in the spreading of seeds.
A．a(chǎn)nimalsB．droppingsC．fruitsD．winds
小題4:This passage is most likely to be found in _______.
A．a(chǎn) travel guideB．a(chǎn) story book
C．a(chǎn) technical reportD．a(chǎn) geography book

There were times when it was only schoolchildren who felt sick before they got their grades．But now teachers in Germany are scared, too, as they are being graded by their students.
Many teachers are opposed to it．They don’t mind being evaluated．But they are upset because the results are then being posted on the Internet and accessible to millions of Internet users．On the website www. spickmich.de during the past four months students have posted evaluations of 100,000 teachers.
The teachers are graded on categories such as “motivated”, “good instruction,” “easy examinations”, or even “sexy.” Many teachers think that their privacy has been violated.
The creators of the website say that the students are only being offered the chance to provide teachers with some feedback about their classroom instruction．Bernd Dicks, who founded the website with three friends, says that the students are largely quite satisfied with their teachers．On a grading scale of one to six, the teachers’ average grade is 2.7 and it has been improving lately．He often says the impression is that students are bullying（欺負(fù)） their teachers．But there is also bullying of the students by teachers.  
“Teachers must also learn to live with criticism,” he added．But still, the website is not totally immune from manipulation（操縱）, as one teacher near the northern city of Hanover recently proved．He registered himself on the website as a student and then rated his own teaching colleagues highly．Within a few days, seven of his colleagues were listed in the top 10 rankings of Germany’s best teachers.
45. Many teachers are opposed to the website because        .
A．their privacy has been violated         B．they are afraid of being assessed
C．their evaluations are unfair       D．the results are not satisfying
46．The founders of the website intended to         .
A．get the students to know their teachers better
B．conduct a survey on teachers’ performances
C．help the teachers to improve their teaching
D．change the teachers’ ways of giving instructions
47．From what the teacher in Hanover did, we can infer         .
A．he intended to help his colleagues
B．there was some disadvantage of the website
C．his colleagues were more popular than him
D．he wanted to know how he was evaluated
48．Which of the following can be the best title of the passage?
A．Teachers get graded by pupils  B．Teachers are angry with website
C．Teachers need self-assessment        D．New invention in assessing teachers
