　　1. It is a new term in today's tourism industry．But in an age of growing environmental awareness, it is not too difficult for us to imagine and understand this new form of holiday．

　　Ecotourism, which is considered as a kind of responsible tourism, is typically defined（定义）as travel to places where special and unusual plants, animals and cultural heritages （遗产） are the main ttractions．  2.

It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial considerations.

　　Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee’s is one of them.

　　The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制药的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities.

　　Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”

1.By “a one-way street” in Paragraph One, the author means ________.

　 A. university researchers know little about the commercial world

　 B. there is little exchange between industry and academia

　 C. few industrial scientists would quit to work in a university

　 D. few university professors are willing to do industrial research

2.The underlined word “deterrent” most probably refers to something that ________.

　 A. keeps someone from taking action      B. helps to move the traffic

C. attracts people’s attention              D. brings someone a financial burden

3.What was Helen Lee’s major consideration when she changed her job in the middle of her career?

A. Flexible work hours.                        

B. Her research interests.

C. Her preference for the lifestyle on campus.

D. Prospects of academic accomplishments.

4. Guy Grant chose to work as a researcher at Cambridge in order to ________.

　 A. do financially more rewarding work

　 B. raise his status in the academic world

　 C. enrich his experience in medical research

　 D. exploit better intellectual opportunities

5.What contribution can industrial scientists make when they come to teach in a university?

　 A. Increase its graduates’ competitiveness in the job market.

　 B. Develop its students’ potential in research.

　 C. Help it to obtain financial support from industry.

D. Gear its research towards practical applications.

It is Saturday afternoon. You and your friends are planning to go to the movies and then spend the night together. Just as you start to get ready, your dad reminds you that it is your aunt's birthday and the whole family is going out to dinner to celebrate. How can this possibly end without a huge argument?

　　One of the greatest sources of tension (紧张情绪) between teenagers and their families is the struggle to balance personal desires with family expectations. As you are getting older, you are becoming more independent and more interested in being with your friends.

　　However，at the same time，your family is trying to figure out how to deal with these changes. While you once spent most of your free time with your family, you are now often absent from home. Parents may get their feelings hurt. Or they might feel that they are losing control of their family during this period. You might feel angry that so many family demands are placed on you.

　　There are a few things you can try to make it a little easier to ease (缓解) the tension.

　　* Make your plans in advance. Ask your parents if there is anything else planned at that time.

　　* When something with your friends interferes (冲突) with a family event，try to figure out if there is any way you can do both.

　　* Suggest something you would really like to do with your family. Sometimes parents feel better just knowing their teenager wants to spend time with them.

　　Some of the time you won’t be happy with the outcome (结果). You might either have to disappoint your parents or have to miss out being with your friends. However, if you show consideration for the feelings of both your family and your friends，you can solve the problem in a tender way.

The purpose of the first paragraph is to _________.

　　A. show a disagreement of views       B. serve as a description of teenager trouble

　　C. serve as an introduction to the discussion

　　D. show the popularity of teenager problem

The tension between teenagers and their families is caused by the fact that____________.

　　A. teenagers don’t like to take family demands

　　B. parents want to keep their family under control

　　C. parents feel unhappy that their children make so many friends

　　D. both parents and teenagers don’t pay attention to each other’s feeling much

What’s the purpose of the passage?

　　A. To inform us of parent and teenager tension.

B. To advise teenagers how to deal with their tension with their families.

　　C. To persuade parents to show consideration for teenagers.

D. To tell us about a common teenager problem.

     Apparently，we are safe neither at home nor in the business office.We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

　　Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.

　　These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.

　　We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

What is the main idea of the first paragraph?

　　A.The air we breathe in is harmful.

B.Chemicals are released in the running water.

C.Chemicals are added to the drinking water.

　　D. The water in everyday use is unsafe.

.In Paragraph 2, the underlined sentence means that .

　　A. homes and offices should be aired often

　　B. any pollution should be taken into consideration

　　C. bathing should be done with caution

　　D.we should prevent any pollution from doing harm to us

What is the purpose of the passage?

　　A.To call on us to guard our water.

　　B.To show us that no place is like home.

　　C.To make us aware of the pollution around us.

　　D.To argue that neither homes nor offices are safe.
