阅读理解。     Searching the Internet may help middle-aged and older adults keep their memories sharp, US researchers
said.
     Researchers at the University of California, Los Angeles, studied people doing web searches by recording
their brain activity.
     "What we saw was people who had Internet experience used more of their brain during the search," Dr.
Gary Small, a UCLA expert on aging, said, "This suggests that just searching on the Internet may train the
brain and that it may keep it active and healthy."
     "This is the first time anyone has simulated (模拟) an Internet search task while scanning the brain," Small
said. His team studied 24 normal volunteers between the ages of 55 and 76. Half were experienced at searching
the Internet and the other half had no web experience. However, the two groups were similar in age, gender
and education.
     Both groups were asked to do Internet searches and book reading tasks while their brain activity was
monitored.
     "We found that in the book reading task, the visual cortex-the part of the brain that controls reading and
language-was activated," Small said, "In doing the Internet search task, there was much greater activity, but
only in the Internet-savvy (了解) group."
     He said it appears that people who are familiar with the Internet can engage in a much deeper level of brain
activity. Activities that keep the brain engaged can preserve brain health and thinking ability. Small thinks
learning to do Internet searches may be one of those activities. 1. Researchers _____ when volunteers were doing web searches. A. studied the Internet
B. activated the brain
C. monitored the brain activity
D. recorded their memories 2. The two volunteer groups were _____. A. of the same age
B. similar in education
C. good at the computer
D. book lovers 3. According to the passage, we can learn that _____. A. searching the web keeps the brain more engaged
B. reading books keeps the brain more engaged
C. watching TV keeps the brain more engaged
D. chatting online keeps the brain more engaged 4. Which of the following is TRUE? A. When you read, the whole brain will be activated.
B. Dr. Gary Small is a UCLA expert on brain health.
C. People who read books may have a better memory.
D. Internet searches can preserve brain health and thinking ability 5. What can we conclude from the last paragraph? A. Web searching is good for the brain.
B. Web searching damages the brain.
C. Activities are good for the brain.
D. Activities damage the brain.

阅读理解。     Driving a large truck over mountain roads is not the usual way that a schoolteacher begins her day-
especially if she is a preschool teacher. But Mrs. Beth Miller does this five days every week. Her unusual
schoolhouse on wheels is actually a truck. The back of the truck has been made into a classroom in order
to carry the advantages of modern education to remote areas of the state of West Virginia. In many rural
areas of this state it is impossible for small children to go to regular schools because of the many hills and
valleys of Appalachian Mountains.
     The purpose of the schoolhouse on wheels project is to develop basic skills and social behavior in
children three to five years of age. This is done through games, exercises, toys and simple handcrafts. The
schoolhouse on wheels concept also teaches the young children to recognize 300 to 400 words on the printed
page. This is a great advantage in helping the pupils to learn to read when they begin regular school. In its
three-year history the project has helped about 350 children in an area made up of five counties, an area of
20 000 square kilometers. The schoolhouse on wheels is part of the Appalachian Educational Laboratory, a
research effort paid for by the government. Besides the mobile classroom, other parts of the program include
lessons by television and visits to the homes of the students. The technique is very effective, and one teacher
can do the work of seven in a traditional educational system. As a result the program costs about 50% less
than the regular kindergarten.
     All these advantages of the schoolhouse on wheels have made both parents and school officials happy.
West Virginia plans to increase the program and to include it in the public school system so that more than
4500 preschool children can have this valuable learning experience. 1. Mrs. Beth Miller usually _____. A. walks to begin her work
B. drives a large truck to begin her work
C. drives her car to the school
D. carries the classroom to the school 2. Children in many rural areas of West Virginia cannot go to regular schools because _____. A. large trucks cannot go in mountainous areas
B. there are no schoolhouses on wheels there
C. there are many hills and valleys there
D. preschool teachers don"t like to work there 3. The best title for this passage is _____. A. Schoolhouse on wheels
B. West Virginia
C. Effective educational system
D. Educational laboratory

阅读理解。     Alaskan black bears hibernate for up to seven months a year, during which time they do not eat or drink,
before waking up in virtually the same physical state they fell asleep in.
     Now experts hope to develop methods of putting humans into a similar state which could help astronauts
survive long missions and lead to new ways of treating severely ill patients.
     While many studies have examined hibernation in mice and hedgehogs, little research has been done into
the same condition in larger mammals such as bears.
     But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the
animals" body temperature, heart rate and muscle movements while they slept.
     The research results showed that during a five-month hibernation the bears" body temperatures varied
between 30~C and 36℃ in cycles that lasted between two and seven days-a pattern that was previously
unknown in hibernating animals.
     The research project leader said, "If our research could help by showing how to reduce metabolic (新陈
代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply
need to know how to turn things on and off to take advantage of the different levels of hibernations."
     Craig Heller, of Stanford University, who contributed to the study, added, "There has always been a thought
that, if there is ever long-distance space travel, it would be good to be able to put people into a state of lower
metabolism or a state of hibernation. That"s almost science fiction but you can see the logical basis." 1. We know from the text that _____. A. during winter Alaskan black bears sleep for more than half a year
B. researchers have examined hibernation in humans
C. experts have got no results from their research
D. Craig Heller is a leader from the Institute of Arctic Biology2. The best topic of the text should be _____. A. The Latest Research Results
B. New Methods of Putting Humans into Hibernation
C. Alaskan Black Bears Hibernate
D. Astronauts Could Hibernate Like Bears 3. According to the text, we can infer that _____. A. many studies have examined hibernation in mice and bears as well
B. humans" body temperatures vary between 30℃ and 36℃ while they sleep
C. research into hibernation in animals may help deadly patients stay longer
D. scientists have already take advantage of the different levels of hibernation in space missions

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。      It"s not that hard to be a better writer. Seriously, it"s especially true if you"re starting as a non-writer
who"s just trying to be competent for day-to-day tasks.
     1. Have a structure. 1_____ Your body should consist of paragraphs that are grouped according to
topic, each one dealing with a single element of your subject.
     2. 2_____ When you say a car runs "fast", don"t leave it at that. Show me how fast it is by detailing
the vehicle"s top speed and acceleration, along with listing other cars it leaves in the dust. Do the same
with every other significant modifier (修饰语) you use.
    3. Don"t pad words. 3_____ Most of the time, this ends up turning what"s essentially nice writing into
unreadable nonsense. You"ll see this with heavy use of unnecessary adjectives and adverbs, along with
useless phrases that can easily be cut off without losing meaning.
     4. Choose good words. Sometimes, the way your text reads comes down to word choice. Don"t say
"converse" when you can say "speak"; don"t write "adjudicate" when you say "decide". 4_____

阅读理解。     "Choo, Choo!" Here comes the Chunnel train. Get aboard if you want to learn more about this underground
transportation system. This is an unusual form of transportation, because it is a tunnel that trains travel through
and not an actual form of transportation.
     The Chunnel is actually the English nickname for the Channel Tunnel. In French, it is called le tunnel sous
la Manche. It is a rail tunnel beneath the English Channel at the Straits of Dover. It connects Cheriton in Kent,
England with Sangatte in northern France. It is the second longest rail tunnel in the world.
     Did you know that the British and the French had a race while they were building the Chunnel? The race
was to see who could get to the middle of the tunnel first. The British won by a little bit. It took 15 000 workers
over seven years to dig the tunnel. The tunnel was finished in 1994.
     The completed Chunnel cost about $ 21 billion. But it all paid off, because it became very popular, very
quick. Millions of people use it. Now it is getting even more popular.
     There are three complete tunnels in the Chunnel. The two outside ones are the passenger trains. The small
inner one is a guidance train. The guidance train is not used for transportation. Each track is exactly parallel to
each other.
    There are four different train systems in the Chunnel. The Eurostar is a high speed passenger service that
connects London, Paris, Brussels, and Lille. The Eurotunnel shuttle is a rail ferry service. These shuttles carry
cars and vans. These are railcars that allow drivers to drive their vehicles on and off. There are also two
Eurotunnel goods service trains.
     Now you know more about the Chunnel. Everybody off, this is the last stop. 1. The Channel Tunnel links ______ with ______. A. London; Paris
B. Cheriton; Sangatte
C. Lille; Brussels
D. Dover; Kent 2. Which of the following shows the structure of the tunnels in the Chunnel? A.

3. The Eurotunnel shuttle is intended to carry _____. A. passengers
B. drivers and their vehicles
C. goods
D. staff members of the Chunnel 4. The text can most probably be _____. A. found in a guidebook
B. read in a magazine
C. broadcast on a train
D. heard in a railway station

阅读理解。     In 1890 William James, the American philosopher and physician and one of the founders of modern
psychology, defined psychology as"the science of mental life" and this definition provides a good starting
point for our understanding even today. We all have a mental life and therefore have some idea about what
this means, even though it can be studied in rats or monkeys as well as in people and the concept remains
difficult to understand.
     Like most psychologists, William James was particularly interested in human psychology, which he
thought consisted of certain basic elements: thoughts and feelings, a physical world which exists in time
and space, and a way of knowing about these things. For each of us, this knowledge is primarily personal
and private" It comes from our own thoughts, feelings and experience of the world, and may or may not
be influenced by scientific facts about things. For this reason, it is easy for us to make judgments about
psychological matters using our own experience as a standard. We behave as amateur psychologists when
we offer opinions on complex psychological phenomena. However, problems arise when two people
understand these things differently. Formal psychology attempts to provide methods for deciding which
explanations are most likely to be correct, or for determining the circumstances under which each applies.
The work of psychologists helps us distinguish between inside information, which is subjective, and may
be prejudiced and unreliable, and the facts: between our predictions and what is"true" in scientific terms.
     Psychology, as defined by William James, is about the mind or brain, but although psychologists do study
the brain, we do not understand nearly enough about its workings to be able to comprehend the part that it
plays in the experience and expression of our hopes, fears, and wishes, or in our behaviour during experiences
as varied as giving birth or watching a football match. Indeed, it is rarely possible to study the brain directly.
So, psychologists have discovered more by studying our behaviour, and by using their observations to obtain
hypotheses (假设) about what is going on inside us. 1. The first paragraph is mainly about _____. A. the founder of modern psychology
B. the definition of psychology
C. the complexity of psychology
D. the influence of psychology 2. From Paragraph 2, we can know that problems arise because _____. A. of the difference between inside information and the facts
B. of different thoughts and feelings about psychology
C. people usually make judgments based on their own ideas
D. amateur psychologists cannot use scientific terms 3. According to the passage, psychologists study the brain mainly _____. A. in a direct way
B. with their own experience
C. by observing how it works
D. by watching people"s behaviour 4. Which of the following can be the first sentence in the fourth paragraph? A. Psychology is also about the ways people use their mental abilities to operate in the world around them.
B. William James is considered to be the greatest psychologist in the 1890s.
C. Psychology suggests that living beings adapt to a changing environment so that they can survive.
D. It is important for psychologists, as well as ordinary people, to be aware of the reasons.
