surprise. The car is fitted with a remote immobilizer, and a radio signal from a control centre miles away
will ensure that once the thief switches the engine off, he will not be able to start it again.
The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro-processor
and memory, and a GPS (全球定位系统) satellite positioning receiver. If the car is stolen, a coded (编
码的) cellphone signal will tell the control centre to block the vehicle"s engine management system and
prevent the engine being restarted.
In the UK, a set of technical fixes is already making life harder for car thieves. "The pattern of vehicle
crime has changed," says Martyn Randall, a security expert. He says it would only take him a few minutes
to teach a person how to steal a car, using a bare minimum of tools. But only if the car is more than 10
years old.
Modern cars are far tougher to steal, as their engine management computer won"t allow them to start
unless they receive a unique ID code sent out by the ignition (点火) key. In the UK, technologies like this
have helped achieve a 31% drop in vehicle-related crime since 1997.
But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner"s keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.
If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an
operations centre that it has been stolen. The hundred metres minimum avoids false alarms due to
inaccuracies in the GPS signal.
Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police
informed of the vehicle"s movements via the car"s GPS unit.
B. help the police make a surprise attack on the car thief
C. prevent the car thief from restarting it once it stops
D. allow the car to lock automatically when stolen
B. self-prepared tools are no longer enough for car theft
C. the thief has to make use of computer technology
D. the thief has lost interest in stealing cars over 10 years old
B. A unique ID card
C. A special cellphone signal
D. A GPS satellite positioning receiver
B. contact the car owner
C. block the car engine
D. locate the missing car

calling her but I couldn"t get through. So I sent her an e-mail and then I spoke to her on MSN. Without
technology I would not have been able to tell her. "
Staying connected with friends and family is important for us. That"s why we asked our readers to tell
us how cell-phones, e-mail, blogs, text messaging, and personal pages help them keep in touch. More
than 1,500 responded.
Most of them told us they couldn"t live without technology: 80％of teens said they need technology to
stay in touch. Almost 30％said they"d be completely out of their
friends without their cell-phones and other methods of communication.
What do they do when they"ve got news they need to share now? Most teens say they try to reach
their friends
by phone. But if they don"t reach them, they use QQ, e-mails, and text messaging to get the words out.
Lots of people use one way of communication-like text messaging-to get a friend"s attention and then
use another where they can talk more. "My friends and I always tell each other everything that happens.
So I send them text messages to tell them to
come online so we can talk about it," said Sabeiha. "When planning to get together with friends", Julian said, "the easiest and fastest way I know is to
send a text message to my contact group." Jocelyn said. "If I want to go to see a movie with a few
friends, I usual
ly send text message to them. By telephone, you have to call every single friend one by one. But text messaging allows you to send the same message to as many as you"d like, which saves a lot
of time."

(紫外线) while skiing in the snow-covered areas than sitting on the beach, according to a report by the
UK newspaper The Telegraph.
The researchers at Kanazawa Medical University, Japan and American company Johnson conducted
the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail (a
rough path) in Ishikawa District, northern Japan. They compared the results with the levels of UV rays
on a sand beach in southern Japan"s Okinawa District. They found that on the beach, eyes are exposed
to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules in snow-covered
areas.
The findings are supported by the Japan Meteorological Agency. According to the agency, the
reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in
the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.
Most of us know that UV rays can harm the skin. That"s why we wear sunscreen on our skin before
we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes.
If your eyes are exposed to large amounts of UV radiation over a short period of time, you may
experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange
feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes
permanent damage to the eyes.
Long-term exposure to UV radiation, however, can be more serious. Scientific studies and
researches have shown that exposure to small amounts of UV radiation over a period of many years
increases the chance of eye damage, which could lead to total blindness.

eyes. You"re thinking. You"re breathing. You"re listening. Possibly you"re shifting(变换) positions. You"re
also feeling things—this book, your chair, emotions. What lets you do all these things at the same time?
Your brain.
Your brain is the control center of your body and mind. Without your brainyou can"t do anything. Your brain has more than 100 billion nerve(神经) cells. Each nerve cell makes from 1,000 to 10,000 connections with other nerve cells. The nerve cells send impulses back and forth in your brain and to and
from every part of your body. After you reach the age of 20, though, your brain cells start to die. This is
common. However, if you suffer an illness, or injury, even more nerve cells die in your brain. When a
nerve cell dies, the thousands of connections it made with other nerve cells are lost.
Until recently, scientists believed that the brain did not replace its dead cells. New studies, however,
prove not. Scientists have found new nerve cells in a part of the brain called the hippocampus(海马区).
The hippocampus helps the brain form memories from new experiences.
The discovery of these new nerve cells is not a cure for anything yet. It gives hope,
however, of a curefor brain damage from such things as epilepsy(癫痫病), Lou Gehrig"s disease, car accidents, and strokes. Someday scientists might be able to use the new cells to replace damaged brain cells. Such a cure,
how
ever, may take about ten years to develop. So at the same time, use your head—protect it!B. make connections only to other cells in the brain
C. can cure Lou Gehrig"s disease
D. are a person"s memory
B. should be careful not to injure their brains
C. have a skull (头盖骨) that provides all the protection needed by the brain
D. would see a quick cure for brain disease
B. comparing it to other parts of the brain
C. telling how it got its name
D. explaining what it does
B. disorders
C. memories
D. messages
surprising relationship between what female teachers think and what female students learn: If a female
teacher is uncomfortable with her own math skills, then her female students are more likely to believe
that boys are better than girls at math.
" If these girls keep getting math-anxious female teachers in later grades, it may create a snowball
effect on their math achievement," Levine told Science News. In other words, girls may end up learning
math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are
better at math than girls are, then these girls may not do as well as they would have if they were more
confident.
The researchers also gave the students tests to tell whether the students believed that a math
superstar had to be a boy. Then the researchers turned to the teachers: To find out which teachers
were anxious about math, the researchers asked the teachers how they felt at times when they came
across math, such as when reading a sales receipt. A teacher who got nervous looking at the numbers
on a sales receipt, for example, was probably anxious about math.
Boys, on average, were unaffected by a teacher"s anxiety. On average, girls with math-anxious
teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus, on the
test showing whether someone thought a math superstar had to be a boy, 20 girls showed feeling that
boys would be better at math - and all of these girls had been taught by female teachers who had math
anxiety.
According to surveys done before this one, college students who want to become elementary
school teachers have the highest levels of anxiety about math. Plus, nine of every 10 elementary teachers
are women, Levine said.
1. Which of the followings is NOT the study mentioned in the passage?
A. Girls may be bad at math because of their female teachers" anxiety.
B. Most students tend to believe that a math superstar has to be a boy.
C. What kind of teachers is more likely to have math anxiety.
D. On average boys are also affected by a teacher"s anxiety.
2. What can you infer from the second paragraph?
A. Girls can do as well as boys if they are confident.
B. Girls are born much weaker than many boys.
C. Boys are stronger and better in math than girls.
D. Girls who are bad at math can do other things better.
3. According to the last paragraph, Levine"s imply attitude to the math teaching in elementary schools
is _______.
A. hopeful
B. disappointed
C. worried
D. content
