　　Robot Cars to Do Battle in Desert Race
　　When 15 competitors lined up in Nevada last year for the U.S. Defense Department's first million-dollar robot race, hopes were high. The challenge: to drive a vehicle without a human driver or remote control some 150 miles (241 kilometers) through the Mojave Desert.
　　But those hopes quickly went up in a cloud of dust as most robots barely managed to get off the starting line. The best performer, a modified Humvee built by engineers at Pennsylvania's Carnegie Mellon University, traveled 7 miles (11 kilometers) before breaking down.
　　To robot devotees(热爱者), however, it was a minor hiccup.
　　No surprise, then, that 43 teams showed up to try out for this year's race, dubbed(被称作) the Grand Challenge. For the past week, teams ranging from garage enthusiasts to well-funded university engineers have been fine-tuning their machines at qualifying rounds here at the California Speedway in Fontana, California. (Watch the robots in action in our exclusive video.)
　　Twenty-three finalists were announced Thursday for Saturday's Grand Challenge. The 175-mile (282-kilometer) course starts and finishes in Primm, Nevada.
　　The race promises to be even tougher than last year's run. But 18 months is an eternity in the robotics world, and the technology has vastly improved.
　　Organizers believe several teams have a real shot of finishing the race in less than ten hours to earn the grand prize of two million U.S. dollars.
　　"When the first team out of the chute(斜道)—Mojavaton, a small team out of Colorado—made it successfully around the 2.2-mile (3.5-kilometer) qualification course, I knew right there and then that we had something special," said Ron Kurjanowicz, the chief of staff for the Pentagon's Defense Advanced Research Projects Agency (DARPA), which is sponsoring the race.
　　Unknown Course
　　The aim of the Grand Challenge, Defense Department officials say, is to spur development of autonomous ground vehicles that can operate in dangerous environments, such as war zones, keeping soldiers out of harm's way.
　　A U.S. Congress mandate(训令)requires that one-third of military ground vehicles drive themselves by 2015, but the technology to meet that mandate does not yet exist.
　　So the government looked to enterprising teams to develop the technology for driverless vehicles, sweetening its offer with the two-million-dollar purse.
　　None of the 23 teams knows what lies ahead for this year's race. DARPA won't reveal the exact route until two hours before the start of the race on Saturday.
　　But the obstacles on the Fontana qualification course-including a steel—enforced tunnel that wipes out a vehicle's global positioning system—are made to resemble the rugged, real-life conditions that the vehicles will have to navigate.
　　The vehicles use sensors such as lasers, cameras, and radar to help them avoid obstacles such as rocks and cliffs. The computer's brain has to figure out how to resolve unexpected conflicts, like a boulder sitting in the middle of the road.
　　"Think about all the decisions that you and I have to make when we drive from our house to the store," Kurjanowicz said. "These vehicles have to do the same thing, without a driver."
　　Among the top contenders in Saturday's race is TerraMax, a massive truck originally built by the Wisconsin-based Oshkosh Truck Corporation for the U.S. Marine corps.
　　In last year's race, TerraMax managed to go only 1.2 miles (2 kilometers). Team leader Gary Schmiedel expects to do much better this year. He pointed to the new all-wheel steering feature on the truck as an important addition.
　　"We can move this large, 15-ton (13.5-metric ton) payload vehicle in a turn that's equivalent to that of a Humvee," he said.
　　Ghostrider
　　The resources of teams like TerraMax or Carnegie Mellon University, which has two vehicles in the race this year, are a far cry from those of some of the other competitors, including inventors, electricians, and even a high school team.
　　One entry, from a Southern California team of engineers, racers, and hot-rodders, is called It Came From the Garage. It has a beer keg(小桶)stuck on the back and an on-off switch that says "brain."
　　"Most of the schools and organizations we're up against are just accessorizing conventional vehicles," said team leader Chris "C.J." Pedersen, a former actor. "Our [vehicle] is a custom-built, 21st-century hot rod... complete with hood scoop and exhaust coming off the side."
　　Anthony Levandowski, a robotics builder from Berkeley, California, is back with Ghostrider, the only motorcycle robot in the qualifications. Studded with sensors and computers, it toppled (翻倒)over after 3 feet (1 meter) in last year's race.
　　Levandowski, who had to postpone his graduate studies when he couldn't find a faculty advisor who believed it would be possible to build the motorcycle robot, says his vehicle has some distinct advantages.
　　"We're smaller and go a lot more places," he said while tinkering with the robot before another trial run. "We're also a lot less expensive. This bike costs as much as a tire or a wheel of some of these other guys' machines."

　　Smart Money
　　Neither Ghostrider nor It Came From the Garage made the final cut this week's qualifying races.
　　However, another crowd-pleaser, Cajunbot—or the Ragin' Cajun—a converted all-terrain vehicle developed by a team from the University of Louisiana in Lafayette, did.
　　The smart money in Saturday's race may be on Stanley, a converted Volkswagen Touareg made by a team at California's Stanford University. It was the only vehicle that didn't hit an obstacle in the trial runs.
　　Even if none of the vehicles finishes the race this year, DARPA's Kurjanowicz said, the event has succeeded in galvanizing robotics developers and pushing the creation of new technologies.
　　"The beauty of the Grand Challenge is that it doesn't tell people how to solve the problem," he said. "The community has come up with its own elegant solutions."
　　1. The passage mainly describes the advantages and disadvantages of robot car races.
　　2. Last year's robot race in Nevada was a great success.
　　3. It is a surprise that up to 43 teams came for this year's race called the Grand Challenge.
　　4. The Pentagon's Defense Advanced Research Projects Agency(DARPA) is sponsoring the race.

　　Section B
　　Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked [A], [B], [C] and [D]. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the center.
　　Passage One
　　Questions 57 to 61 are based on the following passage.
　　It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions, the basis for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.
　　Memory can be defined as the capacity to keep information available for later use. It not only includes "remembering" things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed (嗅出)something suspicious in the grain pile.
　　Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory storage capacity of a computer with that of a human being. The instant access memory of a large computer may hold up to 100,000 "words"—string of alphabetic or numerical characters—ready for instant use. An average U.S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information that the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight.
　　The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person's memory is in terms of words and combinations of words. But while language greatly expands the number and the king of things a person can remember, it also requires a huge memory capacity. It may well be this capacity that distinguishes humans, setting them apart from other animals.
　　57. Which of the following is TRUE about memory?
　　[A] It helps us perceive things happening around us every day.
　　[B] It is based on the decisions we made in the past.
　　[C] It is rooted in our past habits and skills.
　　[D] It connects our past experiences with the present.
　　58. According to the passage, memory is helpful in one's life in the following aspects EXCEPT that ________.
　　[A] it involves a change in one's behavior
　　[B] it keeps information for later use
　　[C] it warns people not to do things repeatedly
　　[D] it enables one to remember events that happened in the past
　　59. What is the author's view about computers and human beings in terms of intelligence?
　　[A] Computers have better memory than a child does.
　　[B] Computers are as intelligent as a teenager is.
　　[C] Computers can understand as many as 100,000 words.
　　[D] Human beings are far superior to computers.
　　60. What is the major characteristic of man's memory capacity according to the author?
　　[A] It can be expanded by language. [C] It may keep all the information in the past.
　　[B] It can remember all the combined words. [D] It may change what has been stored in it.
　　61. Human beings make themselves different from other animals by _______.
　　[A] having the ability to perceive danger
　　[B] having a far greater memory capacity
　　[C] having the ability to recognize faces and places on sight
　　[D] having the ability to draw on past experiences

　　Passage Two
　　Questions 62 to 66 are based in the following passage.
　　"Family" is of course an elastic word. But when British people say that their society is based on family life, they are thinking of "family" in its narrow, peculiarly European sense of mother, father and children living together alone in their own house as an economic and social unit. Thus, every British marriage indicates the beginning of a new and independent family— hence the tremendous importance of marriage in British life.
　　For both the man and the woman, marriage means leaving one's parents and starting one's own life. The man's first duty will then be to his wife, and the wife's to her husband. He will be entirely responsible for her financial support, and she for the running of the new home. Their children will be their common responsibility and theirs alone. Neither the wife's parents nor the husband's, nor their brothers or sisters, aunts or uncles, have any right to interfere with them—they are their own masters.
　　Readers of novels like Jane Austen's Pride and Prejudice will know that in former times marriage among wealthy families was arranged by the girl's parents, that is, it was the parents' duty to find a suitable husband for their daughter, preferably a rich one, and by skillful encouragement to lead him eventually to ask their permission to marry her. Until that time, the girl was protected and maintained in the parents' home, and the financial relief of getting rid of her could be seen in their giving the newly married pair a sum of money called a dowry(嫁妆). It is very different today. Most girls of today get a job when they leave school and become financially independent before their marriage. This has had two results: a girl chooses her own husband, and she gets no dowry.
　　62. What does the author mean by "'Family' is of course an elastic word"?
　　[A] Different families have different ways of life.
　　[B] Different definitions could be given to the word.
　　[C] Different nations have different families.
　　[D] Different times produce different families.
　　63. For an English family, the husband's duty is ________.
　　[A] supporting the family while the wife is financial
　　[B] defending the family while the wife is running the home
　　[C] financial while the wife is running the home
　　[D] independent while the wife is dependent
　　64. Everything is decided in a family ________.
　　[A] by the couple [C] by brothers and sisters
　　[B] with the help of their parents [D] with the help of aunts and uncles
　　65. What is TRUE concerning the book Pride and Prejudice?
　　[A] It is the best book on marriage.
　　[B] It is a handbook of marriage.
　　[C] It gives quite some ideas of English social life in the past.
　　[D] It provides a lot of information of former time wealthy families.
　　66. With regard to marriage in Britain, present day girls differ from former time girls in ________.
　　[A] the right to marry [C] choosing husbands
　　[B] more parental support [D] social position
