阅读理解。     A new study says one part of the human brain may become smaller as the result of a condition
known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag feel
extremely tired for several days. They may also have problems in thinking clearly and remembering.
     Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study,
which involved twenty women who worked for international airlines. They had served passengers on
airplanes for five years. These flight attendants flew across many countries and at least seven time zones.
In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women
spent five days or fewer in their home areas between long flights. The other half spent more than fourteen
days in their home areas.
     The researcher took some saliva from the women"s mouths to measure levels of a hormone  (荷尔
蒙 ) that increases during stress . He tested them to see if they could remember where black spots
appeared on a computer screen .And he took pictures of their brains to measure the size of the brain"s
temporal lobes. (脑叶).
     It was found that the women who had less time between flights had smaller right temporal lobes. This
area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels
of stress hormones.
     The researcher believes the brain needs at least ten days to recover after a long trip. He says airline
workers told him their ability to remember got worse after working on planes for about four years. Other
studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that
controls memory.
     Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find ou
t if too much jet lag could permanently affect memory.1. According to the text, jet lag _____.A. can cause difficulties in speaking
B. can make people feel tired for a few weeks
C. can be only found in flight attendants
D. can be caused by flying over several time zones2. It can be inferred from the text that ______.A. the conclusion is refused by many scientists
B. scientists fear that this research is not done properly
C. every scientific conclusion needs the support from many tests
D. the women who were examined in the research were not healthy3. From the result of the research we can see that _____.A. the women who have longer rest at home show better memory
B. the women who fly in short time have smaller right temporal lobes
C. the women who have longer flights fail the memory test
D. the women who rest more than 14 days produce less hormones4. What is the subject discussed in the test?A. The cause of jet lag.
B. A story of a group of flight attendants.
C. The importance of having enough rest after flights.
D. A research about the effects of jet lag on the brain.

     Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to
entertain themselves, after engineers in Japan developed a musical road surface.
     A team from the Hokkaido Industrial Research Institute has built a number of "melody roads", which
use cars as tuning forks(音叉)to play music as they travel.
     The concept works by using grooves(凹槽). They are cut at very specific intervals in the road
surface. The melody road uses the spaces between to create different notes.
     Depending on how far apart the grooves are, a car moving over them will produce a series of high
or low notes, and designers are able to create a distinct tune.
     Patent documents for the design describe it as notches(刻痕) "formed in a road surface so as to
play a melody without producing simple sound or rhythm and reproduce melodylike tones".
     There are three musical strips in central and northern Japan-one of which plays the tune of a
Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some
markings into a road with a bulldozer(推土机)before driving over them and found that they helped to
produce all kinds of tones.
     The optimal speed for melody road is 44 kph, but people say it is not always easy to get the
intended sound.
     "You need to keep the car windows closed to hear well," wrote one Japanese blogger. "Driving too
fast will sound like playing fast forward, while driving around 12 mph[20 km/h]has a slowmotion effect,
making you almost carsick."1. According to the passage, melody roads use________to create different notes.A. cars  
B. grooves
C. spaces between intervals  
D. bulldozers2. We can learn from the passage that the highness of notes is depended on________.A. how far the grooves are
B. how big the grooves are
C. the number of the grooves
D. the speed of the car3. The underlined word "optimal" in the passage might mean________.A. fastest  
B. possible
C. best  
D. suitable4. In order to hear the music well, you have to________.A. drive very fast
B. drive slowly
C. open the windows wide
D. keep the windows closed5. What"s the best title of the passage?A. A New Type of Music
B. Melody Roads in Japan
C. A Musical Road Surface
D. A New Invention in Japan

阅读理解      I heard many parents complaining that their teenage children are rebelling. I wish it were so. At your
age you ought to be growing away from your parents. You should be learning to stand on your own two
feet. But take a good look at the present rebellion. It seems that teenagers are taking the same way of
showing that they disagree with their parents. Instead of striking out boldly on their own, most of them
are clutching (紧握) at one another"s hands for reassurance.
     They claim they want to dress as they please. But they all wear the same clothes. They set off in new
directions in music. But somehow they all end up huddled (聚在一起) round listening to the same record. Their reason for thinking or acting in thusandsuch a way is that the crowd is doing it. They have come out
of their cocoon (蚕茧) into a larger_cocoon.
      It has become harder and harder for a teenager to stand up against the popularity wave and to go his
or her own way. Industry has firmly carved out a teenage market. These days every teenager can learn
from the advertisements what a teenager should have and be. And many of today"s parents have come to
award high marks for the popularity of their children. All this adds up to a great barrier for the teenager
who wants to find his or her own path.
      But the barrier is worth climbing over. The path is worth following. You may want to listen to
classical music instead of going to a party. You may want to collect rocks when everyone else is
collecting records. You may have some thoughts that you don"t care to share at once with your
classmates. Well, go to it. Find yourself. Be yourself. Popularity will come-with the people who respect
you for who you are. That is the only kind of popularity that really counts.

1. In this passage, the author wants to tell ________.
A. teenagers to try to pursue their real selves
B. readers to try to be popular with people around
C. parents to try to control and guide their children
D. people to try to understand and respect each other

2. The author disapproves of rebelling teenagers ________.
A. growing away from their parents
B. following the popularity trend
C. walking a new way on their own
D. turning to their friends for help

3. The phrase "larger cocoon" at the end of the second paragraph refers to ________.
A. the distractive and variable society
B. the dazzling music world
C. the parental care and love
D. the popularity wave in the society

4. What does the author think of advertisements?
A. Convincing.  
B. Instructive.
C. Influential.  
D. Authoritative.

5. According to the author, what might happen when a teenager stands up against the popularity
    wave and follows his/her own path?
A. He/She falls behind the time.
B. He/She loses good friends.
C. He/She faces all kinds of criticism.
D. He/She gains valuable popularity.

阅读理解     The practice of magic includes special words, actions, and objects. Most magic involves a person
called a magician, who claims to have supernatural powers.
     Magic words. To work most magic, the magician sings or speaks special words in a certain order.
These words are called incantations or spells. Some spells form prayers to demons(魔鬼), spirits, or
other supernatural forces. Many societies believe the magic will not work unless the magician recites
the spells perfectly. Other magic words have no meaning, though they supposedly possess power when
spoken by a magician.
     Magic actions accompany the words spoken in performing much magic. Many of these movements
act out the desired effect of the magic. For example, a magician trying to make rain fall may sprinkle(洒)

only experts practice magic. Magicians may be called medicine men, medicine women, shamans,
sorcerers, or witch doctors. In many societies, magicians must inherit their powers. In others, any person
may become a magician by studying the magical arts.
