Directions: Read the text and choose the most suitable heading from this list for each paragraph of the text. There is one extra heading.

 A. Classroom participation

 B. Differences in American university education

 C. Examination system

 D. Competition among students

 E. Honest policy in students' school work

 F(AB) Students' responsibility for learning

  96._________

There is considerable variety in university classrooms in the United States. Because of diverse teaching methods and non-standardized curricula (课程), no two courses are the same.   Undergraduate courses are considerable different from graduate courses. The classroom   atmosphere in expensive, private universities may differ from that in community colleges   which are free and open to everyone.

 97. ________

  Participation in the classroom is not only accepted but also expected of the student in many courses. Some professors base part of the final grade on the student's oral participation. Although there are formal lectures during which the student has a passive role (i.e., listening and taking notes), many courses are organized around classroom discussions, student questions, and informal lectures.

 98. ________

  Many teachers believe that the responsibility for learning lies with the student. If a long  reading assignment is given, instructors expect students to be familiar with the information in the reading even if they do not discuss it in class or give an examination. (Courses are not designed merely for students to pass exams.) The ideal student is considered to be one who is motivated to learn for the sake of learning, not the one interested only in getting high grades.

 99. _________

 Ideally, the teacher-student relationship at universities is characterized by trust. The honor system, put forward by the teacher and the university demands that the student be honest in all areas of school work. Thus, cheating on tests, Plagiarizing (抄袭) in written work, presenting other's ideas as original, and turning in homework completed by someone else are all prohibited (禁止).

  100. _________                          

Relationships between students in the classroom can be cooperative or competitive. International students should not hesitate to ask for help if it is needed. There are courses, however, where grades are calculated in relation to other student's scores. Therefore, in classes where such a grading curve is used, students may be reluctant to share lecture notes or information for fear that their own grades will suffer.

A device that stops drivers form falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.

     The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.

     Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.

     Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.

     In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.

     The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

92.  According to the text, Driver Alert ______.

A. aims to reduce tiredness-related accidents

B. has gone through testing at laboratories

C. aims to prevent drivers form sleeping

D. has been on sale for 12 months

93. How should a driver respond to the sounds from Driver Alert?

     A. By sounding a warning.                       B. By touching the wristband.

C. By checking the driving time.                  D. By pressing the steering wheel.

94. We can learn form the text that the driver needs to stop for a break when his response time is ______.

     A. about 400 milliseconds                       B. below 500 milliseconds

     C. over 500 milliseconds                         D. about 4 minutes

95. When the driver gets sleepy while driving, Driver Alert ______.

     A. moves more regularly                        B. stops working properly

     C. opens the window for the driver                    D. sounds more frequently and loudly

   Special trees that grow faster, fight pollution, produce better wood, and even sense chemical

attacks are being planted by scientists in the US.

   When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered (转基因的) trees.

   Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.

   Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.

   Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.

   The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.

   So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes (基因组).

   However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.

   "It could be destructive," said Jim Diamond, an environmentalist. '"Trees are what is left of our natural environment and home to many endangered species."

   But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.

   They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.

88. Which kind of tree is not the ones that scientists are planting in the US?

A. Trees that worms can't hurt.

B. Trees that can protect themselves at a chemical attack.

C. Trees that can resist wind better.

D. Genetically engineered trees.

89. What caused the American scientists to work on special trees?

A. They think science could give nature a fighting chance against both natural and man-made dangers.

B. Great numbers of trees have been lost due to attacks by viruses.

C. Researchers successfully introduced seeds designed to resist the virus.

D. Tree genomes are mapped out so scientists know how to improve trees.

90. Which of the following was probably the first kind of trees being engineered?

A. Papaya.      B. Pine.      C. Apple.       D. Poplar.

91. Why did critics think engineered trees dangerous? Because _________.

A. these trees can destroy the balance of nature

B. everything except trees has been genetically engineered

C. trees are home to many endangered species

D. these trees may affect normal trees

Section A

Directions: For each blank in the following passages there are four words or phrases marked A, B, C. and D. Fill in each blank with the word or phrase that best fits the context.

Most of us are taught to pay attention to what is said -- the words. Words  66   provide us with some information, but meanings are obtained from so many other   67   that it would hinder our  68   as a partner to a relationship to rely too   69  on words alone. Words are used to   70   only a small part of the many ideas we  71  with any given message. Sometimes we can gain insight into some of those associations if we   72   more than words. We don't always say what we mean or _73  what we say. Sometimes our words don't mean anything _74   “I'm letting off some steam. I don't really want you to pay close attention to what I'm feeling.” Mostly we mean several things  75  . A person wanting to purchase a house says to the current owner, “This step has to be fixed before I'll buy.” The owner says, “It's been like that for years.”  76  , the step hasn't been like that for years, but the _ 77   message is: “I don't want to fix it. We put up with it. Why can't you?” The   78  for a more expansive view of meaning can be developed by examining a message in terms of who said it,   79  it occurred, the related conditions or  80   , and how it was said.

Section B

Directions: Read the following four passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.

(A)

   The majority of astronauts from America have been men. At the start of the space program there was strong resistance from some people against having women in space. However, some women were very keen to become astronauts and in the end they were successful. In 1978, NASA

began the first training program for women astronauts.

   Judy Resnick and Christa McAuliffe were both astronauts and they were both women, but in many other ways they were very different. Both of them were on Flight STS-51-L. Judy Resnick was born in 1949 and studied engineering at university and went on to obtain a PhD in 1977. She was a member of the first group of women selected for astronaut training in 1978, and in 1984, she became the second woman in space. During that flight, she helped to launch three new satellites and she carried out a program of research. She was, in many ways, a professional astronaut whose whole life was devoted to space travel.

   Chrism McAuliffe was born in 1948 and she was an astronaut almost by accident. In 1984, NASA decided to find a teacher who could accompany astronauts into space. They hoped that she would be able to communicate with students from space and encourage every one of them to be interested in space travel. Chrism was a secondary teacher in history and social studies. She was a gifted teacher and she was selected from over 11,000 applicant to go on flight STS-51-L. She was also a very good communicator and she immediately established a very good relationship with the news media(radio, television and newspapers). It was partly because of this that there was a great deal of interest and excitement about the flight. Thousands of students in schools and universities all around the country were looking forward to communicating with Chrism in space. Millions of people were watching her flight with great interest. It is partly because of the excitement over McAuliffe's place in the flight that the disaster in 1986 had such an effect on people.

81.We can learn from the first two paragraphs that ________.

A. Judy was against the idea of having women in space at first

B. Judy was the first woman selected for astronaut training

C. Judy helped to launch three new satellites at the age of 35

82.Christa McAuliffe was chosen for training because ________.

A. she was popular with the news media    

B. she expected to give history lessons in space

C. she was an excellent teacher and communicator 

D. she made the students in space very excited.

83. The reason why there was great interest in Fight STS-51-L is that _______.

A. both Christa and Judy got PhD degree in the same year

B. a young secondary school teacher was on the flight

C. students were going to learn more about space travel

D. it was the first time for women to travel in space

84. What would be the best title for the passage?

A. Two Astronauts    B. Flight STS-51-L   C. Traveling in Space     D. The Training Program
