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 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 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.

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

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

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

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

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

Personal money-management website Mint.com suggests recently that responsible parents should give their kids credit cards—possibly starting as young as middle school. The website says a credit card will help children master responsible spending habits and give parents the chance to teach them some valuable lessons.

It’s absolutely true that kids should learn about how a credit card works and how to use it responsibly. But the idea that they need a card of their own to practise this is questionable.

Yes, credit cards are a teaching tool, but it’s the time you spend educating them about money management that does the teaching, not the piece of plastic. Sit down with your child—here we are referring to teens and walk them through your credit card statements. Point out important things like the due date, late fee warning, and APR (年貸款利率).

If you have good credit, adding a child as an authorized user onto one of your credit cards also provides teachable moments. Allow kids to use the card to make specific purchases and require their participation in payment.

Since the card is still in your name, you can take them off it at any point and cut off their access if they're not able to handle the responsibility.

Another option is to set them up with an account at a local bank that offers free use of a debit card (借記卡). Unlike credit card, the debit card has no overdraft (透支) function.

Children can only use the card to pay for things and the money is taken directly from their bank account. If the account is empty, the worst that will happen is the card being declined at a cash register.

1.Why does Mint.com advise parents to give middle school kids credit cards?

A. To leave their kids financially independent.

B. To help their kids form good spending habits.

C. To teach their kids' how to save pocket money.

D. To strengthen the relationship with their kids.

2.The author considers a credit card as a teaching tool because ______.

A. it motivates teens to ask their parents for less financial support

B. it helps teenagers to know some basic knowledge of credit cards

C. it contains detailed financial information on the card surface

D. it offers parents the chance to teach kids to manage money

3.What is the purpose of adding kids as credit card authorized users?

A. To avoid extremely high overdraft fees.

B. To encourage them to share household expenses.

C. To teach them to be responsible credit card users.

D. To help them pay close attention to their bank account.

4.What is most likely to be discussed in the paragraph that follows?

A. Further information about the debit card.

B. The overdraft functions of a debit card.

C. More disadvantages of credit cards.

D. The kids' attitude towards a credit card.

In my first week as a graduate student at Cambridge University in 1964 I met with a fellow student, two years ahead of me in his studies; he was unsteady on his feet and spoke with great difficulty. This was Stephen Hawking. I learned that he had a bad disease and might not live long enough even to finish his PhD degree.

But, amazingly, he has reached the age of 73. Even mere survival would have been a medical miracle, but of course, he didn’t merely survive. He has become arguably the most famous scientist in the world for his brilliant research, for his bestselling books, and, above all, for his astonishing victory over hardship.

Stephen received his “death sentence” in 1964, when I thought it was hard for him to go on with his study. Stephen went from Albans School to Oxford University. He was said to be a “l(fā)azy” undergraduate, but his brilliance earned him a first-class degree, an “entry ticket” to a research career in Cambridge and a uniquely inspiring achievement. Within a few years of the burst of his disease he was wheelchair-bound, and his speech was so unclear that it could only be understood by those who knew him well. But his scientific career went from strength to strength: he quickly came up with a series of insights into the nature of black holes (then a very new idea) and how the universe began. In 1974 he was elected to the Royal Society at the exceptionally early age of 32.

The great advances in science generally involve discovering a link between phenomena that were previously conceptually unconnected — for instance, Isaac Newton realized that the force making an apple fall to earth was the same as the force that holds the moon and planets in their orbits. Stephen’s revolutionary idea about a link between gravity and quantum(量子) theory has still not been tested. However, it has been hugely influential; indeed, one of the main achievements of string theory(弦理論) has been to confirm and build on his idea. He has undoubtedly done more than anyone else since Einstein to improve our knowledge of gravity and he is one of the top-ten living theoretical physicists.

1.What impressed the author most about Stephen Hawking?

A. His brilliant research.

B. His bestselling books.

C. His serious disease.

D. His defeating hardship.

2.What made Stephen Hawking start his research career at Cambridge?

A. His death sentence.

B. His “l(fā)azy” attitude.

C. His above-average talent and ability.

D. His rich experience.

3.It can be inferred that Stephen Hawking was born ________.

A. in the early 1940s

B. in the late 1940s

C. in the early 1930s

D. in the late 1930s

4.What can we learn from the text?

A. Hawking’s theory was proved years ago.

B. Hawking was not as successful as Newton.

C. String theory built on Hawking’s idea.

D. Hawking’s theory has had little influence on others.

5.Which of the following is Not True according the passage?

A. He achieved one success after another in his career despite his disease.

B. He couldn’t walk when the author first met him at Cambridge.

C. He not only survived his disease but contributed greatly to science.

D. He is among the greatest scientists to improve the knowledge of gravity.
