college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms
scored about eight points lower on math and language arts tests than children without bedroom TVs.
A second study, looking at nearly 1000 grown-ups in New Zealand, found lower education levels among
26-year -olds who had watched lots of TV during childhood.But the results don"t prove that TV is the cause
and don"t ride out that already poorly motivated youngsters (年轻人) may wash lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. These with college degrees
had watched average of less than two hours of TV per weeknight during childhood compared with an average
of more than 2 1/2 hours those had no education beyond high school.
In the California study, children with TVs in their rooms but no computer at home scored the lowest while
those with no bedroom TV but who had home computers scored the highest.
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating
findings that children shouldn"t have TVs in their bedrooms.
B. not be interested ted in math
C. is unable to go to college
D. have had computers in their bedrooms
B. Habits of TV watching reduce learning interest.

a very important exam in the lives of South Korean students.
Although the long, cold winter has already started in South Korea, the annual (一年一度的) national
exams have made the atmosphere very heated.
More than 675,000 South Korean high school graduates (毕业生) took the college entrance exam last
Wednesday. They usually take exams in Korean, maths, sociology (社会学), history and foreign languages.
Officially there is one college place for every 1.33 students. But because all the students want to go to
the top universities in the country, the competition can reach one place for 10 students. The students want
to attend these colleges for both their famous names and better job opportunities.
Because students face fierce competition, they have to study very hard to realize their dreams. Park
Seung said he and his classmates often go to school before 7:30 am. After school has finished at 6:30 pm,
most of them go to the library to continue their study instead of returning home. Since many libraries in
South Korea are open 24 hours a day, they often stay long into the night. Many of the Senior 3 students
only sleep for three to four hours a day.
"I feel a lot of pressure,but I have to study very hard in order to make my dream come true. This is my
lifetime goal and it will be a turning point in my life which could decide my future," Park said.
The exam day is a very serious day for the whole of South Korea. Vehicles are not allowed within a 200-
metre radius (范围) of all the test sites to make sure the students have quiet surroundings. Tooting (吹奏)
of horns is forbidden, even airplanes are ordered to avoid landing and take-off near the test sites during
listening comprehension test hours.
Students are told their scores in December before they apply for college. This is followed by face-to-face
oral tests (口试). There are public and private universities in South Korea. Many private universities are well-
known, but their fees can be 18, 000 yuan each term. This has made a lot of students think again.
B. there is only one top college
C. there are only top universities
D. there are a number of colleges
B. 507, 520
C. 500, 000
D. 600, 000
B. when the test is going on
C. during some period of the test
D. during the tests
B. they will ask questions of colleges
C. they will not be tested any more
D. first they will pay all the education fee at all

The day that a robot wakes you up, cleans your room and walks your dog might still be a few decades
off. But increasingly, engineers are saying that robots are going to make the leap (跳跃) from the factory
floor to your family room.
Companies like Sony and General Electric are working on designs for small robots. Products like the
Roomba, a robot that can clean floors, are flying off the shelves. On the cover of a recent issue of Scientific
American magazine, Bill Gates predicted the "Dawn of the Age of Robots".
What"s behind this new era (时代)? It"s partly a matter of technology. Devices that can recognize and
respond (回应) to a human voice have been developed. There are now a few different ways for robots to
move around. They can walk, crawl (爬行) or ride on wheels. They are being made smaller and smaller.
They are also becoming more and more energy efficient.
A bigger part of the story is on the demand side. From the day Robert Adler invented the television remote
control in the 1950s, people around the world have tirelessly searched for ways to get lazier.
Also take into consideration the increasing wealth of rich people, the time appears ripe to introduce robots
to ease our daily lives.
To be sure, robots that walk on two legs and talk like people are still too complex for our present
engineering abilities. Today"s robot revolution is to make them for everyday use. Robots will do basic
housework such as cleaning or gardening, or just help you have more fun on the basketball court.
What makes a robot different from an ordinary cleaning machine is not the presence of computer chips
(芯片). Nowadays even your microwave has a computer chip. It is the ability to sense and make changes
to the environment (环境) in real time.
For example, a floor-cleaning robot should be able to sense your scared cat and move out of the way.
Today"s computing ability is, for the first time, able to make machines that could "think", at least in certain
limited ways.
such as Star Wars. Today, 1 a lot of things in science stories have been science facts. Robots are starting
to 2 in our everyday lives. These robots have different sizes, shapes and colors. But they all have the same 3 of man-made " 4 ". Leading the robot revolution (革命) are industrial robots that work in factories.
Industrial robots can do different kinds of jobs that are often 5 and sometimes dangerous. Robots are also
coming to American homes, though not as quickly as they are entering 6 . These robots aren"t as friendly
and 7 as those you saw in Star Wars. But, their makers say, today"s home robots "walk" and sense objects
in their own way. They even 8 objects though they may sometimes drop. Well, nobody is 9 .
We may 10 home robots today, but some day they may see and hear 11 than humans do. We 12 can
only see certain wave lengths of light and hear certain 13 . That"s because the 14 of our eyes and ears are
15 . Robots, however, need not have the same limits 16 we have.
Robots may also be 17 wit devices (装置) that 18 information humans can"t. However, to understand
19 their sensing devices pick up is a hard job.
Remember, man-made brains 20 information, including all kinds of data, as zeroes and ones.
Imagine the difficulty in trying to explain to a robot what a football looks like-using only zeroes and ones.

| Do dogs understand us? Be careful what you say around your dog. It might understand more than you think. A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee (黑猩猩). In one experiment, the researchers took all 200 items that Rico is supposed to know and divided the into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn"t see anyone to get clues, the scientists believe Rico must understand the meanings of certain words. In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before. The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination (排除法). A month later, Rico remembered half of the new names, which is even more impressive. Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (种) known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months. It"s hard to know if all dogs understand at least some of the words we say. Even if they do, they can"t talk back. Still, it wouldn"t hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return! | |||
