by that name can now be seen in so many parts of the world. That program became one of American"s exports
soon after it went on the air in New York in 1969.
In the United States more than six million children watch the program regularly. The viewers include more
than half the nation"s pre-school children, from every kind of economic (经济的), racial (种族的), and
geographical group.
Although some educators object to certain elements in the program, parents praise it highly. Many teachers
also consider it a great help, though some teachers find that problems arise when first graders who have learned
from "Sesame Street" are in the same class with children who have not watched the program.
Tests have shown that children from all racial, geographical, and economic backgrounds have benefited
from watching it. Those who watch it five times a week learn more than occasional (偶然的) viewers. In the
US the program is shown at different hours during the week in order to increase the number of children who
can watch it regularly.
The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers,
letters and human relationships. But there are some differences. For example, the Spanish program, produced
in Mexico City, devotes more time to teaching whole words than to teaching separate letters.
Why has "Sesame Street" been so much more successful than other children"s shows? Many reasons have
been suggested. People mention the educational theories (理论) of its creators, the support by the government
and private (私人的) businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important
reason is that mothers watch it along with their children, This is partly be- cause famous adult stars often
appear on it. But the best reason for the success of the program may be that it makes every child watching feel
able to learn. The child finds himself learning, and he wants to learn more.
B. a program for children
C. a program for teachers
D. a program for students
B. will find it a great help
C. will take no interest in their studies
D. will be well educated
B. It makes children feel able to learn.
C. It is shown at different hours during the week.
D. Children learn and enjoy themselves while watching.
B. Because it uses a variety of skillful tricks.
C. Because mothers watch it along with their children.
D. Because it makes every child watching it feel able to learn.

without them. 1_____ But this is the prediction made by a team of transport researchers who are taken
seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an
international research program. 2_____ That will mean much saving, no accidents and better use of roads.
The super-intelligent car of the 21st century will drive itself, 3_____ Instead, we will have a choice of cars
and change them as frequently as we change our clothing.
According to Dr. David Davis, who leads the research team, these predictions are based on the rising
cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both
world wars put together.
Davis says, cars will be fitted with some intelligent devices (装置) to regulate (调节) the distance
between one car and another. 4_____ Computers are much safer drivers than people, so cars in a road train
will be able to drive much closer together than cars driven by people.
By 2020, Dr. David Davis believes,car technology will give motorists a clear view of the road, whatever
the weather conditions, by projecting an image (影像) of the road ahead on to the car"s wind-screen.
5_____ Cars will be connected by an electronic tow bar to the car in front to form" road-trains". "The front
vehicle in such a train burns the normal amount." says Davis. "But all the others in the train would burn about
ten percent of the normal amount, and so produce about ten percent of the pollution."
B. They believe that cars will become more important in 20 years.
C. And it will not be owned by one individual.
D. And by 2030, cars will travel in line, linked to each other electronically.
E. So the idea that in 20 years" time, no one will own cars may be hard to believe.
F. Every driver will use less fuel in the car he owns.
G. The car will automatically speed up, or slow down, to match the speed of the car in front.
After an hour"s flight one of the scientists wrote in his notebook, "Look here for probable metal." Walking
across hilly ground, four scientists reported, "This ground should be searched for metal." From an airplane
over a hilly wasteland a scientist sent back by radio one word "Uranium".
None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth"s
surface. They were merely putting to use one of the newest methods of locating minerals in the ground-using
trees and plants as signs that certain minerals may lie under the ground on which the trees and plants are
growing.
This newest method of searching for minerals is based on the fact that minerals deep in the earth may
affect the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a mineral search group gathered bags of tree seeds. Boxes were filled with small
branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a
scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was
examined to learn whether there were minerals in it.
Study of the roots, branches and seeds showed no silver. But there were small amount of gold in the roots
and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold
than those growing on the ends of the branches.
If the trees indicated that there was no gold in the ground, the scientists wouldn"t spare money to pay for
digging into the ground.
B. study the trees
C. look for gold
D. search for minerals
B. there were smaller amounts of gold in the tree roots deep in the ground than in the branches
C. there were larger amounts of gold in the seeds growing closer to the tree trunk than in the seeds farther
from it
D. there were larger amounts of gold in the branches than in the leaves on the ends of the branches
B. Roots.
C. Branches.
D. Seeds.
B. New methods of doing geological study.
C. Gold could be found in trees and plants.
D. A new method of searching for minerals.
family and friends at all times and in most areas. However, because of the quick acceptance and extensive
usage of mobiles in our lives, we have missed out on an important step, namely, the appropriate (恰当的)
use.
Driving a car
Do not use your phone while you are driving! You could concentrate on your conversation and forget
to look where you are going, or you could take your eyes off the road to look at the phone"s display or to
press in a number. Either way, you could cause a terrible accident.
In a restaurant
There is probably nothing more annoying than a diner receiving or making a call near you when you are
in a restaurant. The icy glares (冷眼) you receive should be warning enough that it is not appreciated. Turn
your phone off and use your message service to return calls after you leave.
At the cinema
Do not give way to the desire to call a friend if the film is boring, or if you want to find out what happens.
You could become the target of all the angry cinema customers.
At the theatre
There is no more icy glare than that of a theatre goer who has paid a lot of money to see a show and hears
your phone playing a tone. It goes without saying that you will be seen as a socially unacceptable person in
this situation.
In hospitals
This is probably the most important place to make sure your phone is switched off. Your phone can disturb
life-saving electronic equipment in hospitals, so it is necessary that your phone is switched off before you
enter.
On planes
Your phone might disturb navigational equipment and cause a horrible accident so you should switch it off
before boarding a plane.
B. a nearby diner is answering a phone call
C. you have to use the message service
D. you can not return calls until after you leave
B. When switched on in hospitals, mobile phones could endanger patients" lives
. C. Passengers should switch off the phones before getting on a plane.
D. Pressing in phone numbers when driving could lead to traffic accidents.
B. the overuse of mobile phones on some occasions
C. some areas where message service is forbidden
D. the proper use of mobile phones in some public places
B. carry on
C. pay particular attention
D. think something clearly
one in two hundred is affected in this matter, Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He
may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference
between blue and green. In rare cases an unlucky man may see everything in shades of green-a strange world
indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small
things called "cones" (圆锥细胞). These help us to see in a bright light and to tell the difference between colors.
There are also millions of "rods" (棒条体), but these are used for seeing when it is near dark. They show us
shape but no color.
Some insects have favorite colors. Mosquitoes (蚊子) prefer blue to yellow. A red light will not attract
insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With
the aid of the cones in our eyes we tan see many beautiful colors by day, and with the aid of the rods we can
see shapes at night. One day we may even learn more about the invisible (看不见的) colors around us.
B. women being luckier than men
C. danger caused by color blindness
D. color blindness
B. see in a weak light
C. kill mosquitoes
D. tell orange from yellow
B. There are fewer color-blind women.
C. Women are fonder of driving than men.
D. Women are weaker but quicker in thinking.
B. None of them can see deep red.
C. None of them can tell the difference between blue and green.
D. All of them see everything in shades of green.
B. yellow light
C. blue light
D. green light
to make years ago when I had to learn Latin, clean my room, stay home and do homework.
That was before we entered the permissive period in education in which we decided it was all right not to
push our children to achieve their best in school.
The schools and the educators made it easy for us. They thought that it was right to be parents who take
a let alone policy. We stopped making our children do homework. We gave them calculators (计算器), turned
on the television, left the teaching to the teachers and went on vacation.
Now teachers, having taught many children who have been developing at their own step for the past 15
years, are realizing we"ve made a terrible mistake. Sharon Klompus is such a teacher who thinks her students
"so passive" and wonders what happened. Nothing was demanded of them. She believes that Television
contributes to children"s passivity. "We"re not training kids to work anymore," says Klompus. "We"re talking
about a generation of kids who"ve never been hurt or hungry. They have learned somebody will always do it
for them. Instead of saying "go and look it up", you tell them the answer. It takes greater energy to say no to
a kid."
Yes, it does. It takes energy and it takes work. It"s time for parents to end their vecation and come back
to work. It"s time to take the car away, to turn the TV off, to tell them it hurts you more than them but it"s
for their own good. It"s time to start telling them no again.
B. they have done too much homework
C. they have to fulfill too many duties
D. teachers are too strict with them
B. discipline
C. natural development
D. education at school
B. when everything can be taught at school
C. when every child can be educated
D. when children are permitted to receive education
