Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part -drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (遠(yuǎn)距離的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (螞蟻) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
小題1:Watchers doubted if any of the vehicles could finish the race because        .
A.they did not have any human guidance
B.the road was not familiar to the drivers
C.the distance was too long for the vehicles
D.the prize money was unattractive to the drivers
小題2:DARPA organized the race in order to         .
A.raise money for producing more robotic vehicles
B.push the development of vehicle industry
C.train more people to drive in the desert
D.improve the vehicles for future wars
小題3:From the passage we know “robotic vehicles” are a kind of machines that         .
A.can do effortlessly whatever tasks living thing can
B.can take part in a race across 142 miles with a time limit
C.can show off their ability to turn themselves upside down
D.can move from place to place without being driven by human beings
小題4:In the race, the greatest distance one robotic vehicle covered was          .
A.a(chǎn)bout eight miles B.six miles
C.a(chǎn)lmost two miles D.a(chǎn)bout one mile
小題5:In the last paragraph, the writer implies that there is a long way to go         .
A.for a robotic vehicle to finish a 142-mile race without any difficulties
B.for a little child who has just learned to walk to reach the cookie on the table
C.for a robotic vehicle to deal with a simple problem that a little child can solve
D.for a little child to understand the importance of wiping apple juice off its face

小題1:A
小題2:D
小題3:D
小題4:A

Before the early 1960’s people interested in the differing roles of the left and right hemispheres(半球) of the brain depended almost entirely on facts drawn from animal research, form studies of patients with one-sided brain damage. But it was possible to find out which brain hemisphere was most involved in speech and other functions in normal people by having them listen to two different words coming to the two ears at the same time. This became known as the “dichotic listening” procedure. When several word pairs are given in a row, people are unable to report them all, and most right-handers prefer to report, and report more correctly, words given to their right ears. This seems to be related to the fact that signals from the right ear, although sent to both hemispheres, are better sent to the left hemisphere which controls speech. People who have speech represented(回憶) in the right hemisphere, a very unusual occurrence even in left-handed people, more correctly report what their left ears hear.
In contrast to the right-ear advantage for speech, there is generally a left-ear advantage for another type of auditory(聽覺的) signal: music. When right-handed people listen to melodic patterns they report them better from the left ear.
小題1:Which of the following would be the most proper title for the passage?
A.An Introduction to Speech Damage in Patients with Brain Damage.
B.An Investigation into the Role of the Brain’s Hemispheres.
C.An Analysis of Left and Right-handed People.
D.An Examination of “Dichotic Listening”.
小題2:The “dichotic listening” procedure could best be described as hearing _______.
A.two different words in the same ear twice
B.the same word twice in the same ear
C.two different words in different ears
D.two different words twice in two ears
小題3:according to the passage, right-handed people normally _______.
A.have better hearing in their both ears
B.have little difficulty in reporting words given to their right ears
C.a(chǎn)re unable to report word pairs given to their left ears
D.correctly report word pairs given in a row
小題4:according to the passage, music is best appreciated when heard by _______.
A.the left ear of right-handers
B.people with a left-ear advantage
C.left-handers in their right ears
D.right-handed people who understand melodic patterns

Learning to save money when you're young is an important lesson. All good lessons arid habits begin early, and saving is a skill that everyone needs. Many people—adults included—do not have a good sense of saving for the long run.     
I have been lucky to learn this lesson early because I have had a grass-cutting business since I was 10 years old. Of the money I make I spend about 10 percent and save the other 90.   
Making sure you save and don't spend too much is a good way to build up wealth. I have put my earnings in a bank. Many teens I know spend all the money they earn so it never has a chance to grow. Young people should realize that their teenage years are a great time to begin saving.   
At high school many parents pay for almost everything, so your expenses can be small. If you have a lob, you should have fun with some of the money. But you should also save some so that it will grow. Then you can begin planning for your future. When you spend money, you not only lose that money, but also lose the interest you could have earned by saving it.   
After high school, college is expensive and then "real" life begins, with expenses such as food and rent. If you can hold onto a good percentage of the money you earn as a teen, going to college and buying a house will be much easier.________________, the more time the money has to grow. If you are in your thirties without any savings, you will always have to struggle. The earlier you begin saving, the easier it is to create a nest egg.  
Later in life it can be hard to start saving because general costs of living are more expensive and you may only have enough to pay your bills. If you want to buy a house and have a family, you need money to start with, which comes from saving.   
Many say money cannot make you happy, and this is true. But money can help you to lead a secure life.     
Saving early will mean you will have to work for fewer years when you are older. It will also allow you to spend time doing the things that you want to do.
In addition to this, it will mean you can live the way you want to without worrying.
1.What’s the best title of the passage? 
2.Which sentence in the passage is the closest in meaning to the following one?
As long as you save early, you’ll do less work to live well at your old age.
3.Please fill in the blank in the passage with proper words or phrases to complete the sentence.(within 10 words)
4 According to the passage,.what do you think of saving ?(within 30 words)
5.Translate the underlined sentence into Chinese.

Recently I was invited to a friend’s house for supper—and had a meal I have never had before.
All the friends invited were a little surprised. It’s not that Ben is unsociable, or a bad cook, but it’s just that he never 21more than he has to. So how come he was inviting us round for a meal? Had he bought something 22for his friends? He greeted us at the door and showed us into his dining room where a 23_ -table was waiting for us.“Nothing but the best for my friends!”said Ben. We all sat down and looked 24 at each other—what was he up to?
Ben returned with four bowls of hot soup.“It’s a mixture of carrots, potatoes and tomatoes,”said Ben. The next 25was also a little strange in that we didn’t quite know what it was again. It’s just another mixture of vegetable.
As we ate we chatted and finally the 26 turned back to what we were eating.“Was there a recipe(食譜) for this,”asked Marina,“or did you 27 it up?”Ben put his fork down.“What I cooked depended on what I could find.”Marina was surprised.“But you can find anything in supermarkets these days.”“But there’s 28 choice in what you can find outside supermarkets,”he replied.
Seeing that we had all finished the food, Ben decided to tell the truth. He had read recently that supermarkets usually throw away 5 percent of their food every day. So Ben decided to look inside his local supermarket bins. There he found food that was slightly out of __29, boxes of throw-away vegetables and fruit.
So Ben had successfully provided a decent(體面的) meal for his friends, and made us aware of the fact that there are many poor people who need the food, but the amount of food thrown away is enough to 30 millions of people.

The global energy crisis is approaching. What can we do? Here are some steps you can take.
Cooling puts the greatest stress on your summer energy bill and the power grid(電網(wǎng)). Just as t tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Clean or replaces filters monthly or as needed.
For central air conditioning systems and room air conditioners, look for the ENERGY STAR, the federal government’s symbol for energy efficiency. For central air, purchase the system with the highest possible Seasonal Energy Efficiency Raton. (SEER)
Use energy-efficient ceiling fans either alone or with air conditioning. Ceiling fans do a great job of circulating air. When used with air conditioning, fans allow you to raise the thermostat(恒溫器) and cut costs. Ceiling fans cool people, not rooms, so before you leave; turn off the ceiling fan.
Let a programmable thermostat! “remember for you” to automatically adjust the indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10 percent. You can come home to a comfortable house without wasting energy and cresting pollution all day while you are at work.
Try to make your home airtight enough to increase your comfort, make your home quieter and cleaner and reduce your cooling costs up to 20 percent.
Gut your air conditioning load, and reduce pollution by planting planting leafy trees around your home and fixing reflective bricks on your roof.
Close blinds or shades on south-and west-facing windows during the day, or fix shading equipment to avoid heat build-up.
Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs(熒光燈), which provide bright, warm light while using at least two-thirds less energy, producing 70 percent less heat and lasting up to 10 times longer than incandescent bulbs(白熾燈).
Drive the car that gets better gas mileage whenever possible if you own more than one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a car that gets 20 mils per gallon to one that gets 30 mpg will save you more than £65 per year.
Carpool. The average U.S. commuter(乘車上班族) could save about £260 a year by sharing cars twice a week with two people in a car that gets 20.1 mpg---assuming the three passengers share the cost of gas.
小題1:According to the passage, the thermostat is used to ______.
A.make rooms quieterB.control room temperature
C.turn off the air conditionerD.reduce room air pollution
小題2:We can conclude from the passage that the author probably discourages ______.
A.planting leafy trees around your home
B.turning off the ceiling fan before you leave your house
C.keeping your south-facing windows open during the day
D.using fluorescent bulbs instead of incandescent bulbs

“Sesame Street” has been called “the longest street in the world”. That is because the television program 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(經(jīng)濟(jì)的), racial(種族的), 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(理論) 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 because 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.
小題1:“Sesame Street” is actually _______.
A.a(chǎn) street in the US B.a(chǎn) program for children
C.a(chǎn) program for teachersD.a(chǎn) program for students
小題2:Children who often watch the program _______.
A.can have problems in school
B.will find it a great help
C.will take no interest in their studies
D.will be well educated
小題3: What is special about the program?
A.It offers great fun.
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.
小題4: Why is “Sesame Street” so popular in the world?
A.Because it is supported by the government and businesses.
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.
小題5:The best title for this passage can be _______.
A.TV ProgramsB.Educating Children

“The first and best of victories is for a man to conquer himself; to be conquered by himself is, of all things, the most shameful,” says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses and feelings, and from that moment he gives up his moral freedom.
A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease “Whom the gods would destroy they first make mad.” “Keep cool,” says George Herbert, “for fierceness makes error a fault.”
To be angry with a weak man is to prove that you are not strong your self. “Anger,” says Pythagoras, “bring with folly and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man’s last greatest victory.  
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also.
小題1:What does the reader learn from the first paragraph ?
The greatest victory for a man is to conquer everything except himself.
One’s moral freedom is based on the control of himself.
To control oneself is the most difficult in one’s life.
If a person is too stubborn, he will feel most shameful.
小題2:What is the correct interpretation of “Whom the gods would destroy they first make mad”?
If the gods want to kill you, they make you crazy first.
If you always lose your temper, you will soon be finished.
If you cannot control yourself, you will become crazy.
If you are mad, you will be punished by the gods.
小題3:If a man lacks self-control, he lacks all of the following EXCEPT _________.
the very backbone and nerve of character
the patience and power to control himself
strong feelings
self-confidence
小題4: The author’s main purpose in writing this article is to ___________.
explain that self-control is the key to success
teach people how to control everything in order to make a great success
distinguish all kinds of self-control and suggest ways for keeping it
advise people not to lose temper so as to make and keep more friends
