20．Want to be a great doctor or scientist？Make sure you play video games．New research shows that certain video games can help people find things better and faster．
For instance，if a doctor is looking for something on an X-ray，or if a scientist is looking at a satellite image，they may be able to do it better if they've been"trained"by playing video games．Certain video games，like driving games，can improve a person's"visual search skills"．That's the ability to see something that's hidden in the middle in a confusing field of things．
Researchers at the University of Toronto studied three groups of people：20people who played a shooting game called Medal of Honor，20people who played the driving game Need for Speed，and 20people who played a puzzle game called Balance．
"The people who played the shooting and the driving games became faster and more accurate at searching for things．The people who played the puzzle game did not improve their ability to find things faster，"said Sijing Wu，the lead author of the study．
Researchers also compared video game players with people who didn't play video games on three visual search tasks．They found that the experienced players were better．
"We have shown that playing a driving game can produce the same benefits as playing a shooting game，"said Wu．"This could be very important in situations where we wish to train people to improve them．Driving games are likely to be more acceptable than shooting games because of the lower levels of violence．And young kids are not encouraged to play any violent video games．"
29．"Visual search skills"refer to the ability toD
A．design new video games
B．do science research successfully
C．prevent something from being known by others
D．find something among many things in confusing fields
30．We can infer from the passage thatB
A．someone who plays video games performs better at school
B．playing video games may also be a kind of training
C．no one can tell who will succeed finally in a game
D．it's very easy to learn to play video games
31．In this passage，the author mainly wants to tell usB
A．the newly developed video games
B．the positive side of playing video games
C．the troubles caused by playing video games
D．the necessity of giving up playing video games．

分析文章主要讲述了玩电子游戏可以帮助人找到一些隐藏在其他事物中的东西，这也是锻炼自己视觉搜索能力的一种行为．作者通过科学家的实验进行举证，说明玩电子游戏也可能是有一定好处的．

解答 29．D 细节理解题．根据第二段最后一句话"Certain video games，like driving games，can improve a person's"visual search skills"．That's the ability to see something that's hidden in the middle in a confusing field of things．"视频游戏可以提高一个人的视觉搜索能力，这是一种在混乱的领域里看到隐藏在中间的东西的能力，可知．结合选项故选D．
30．B 推理判断题．根据第四段一二句"Researchers also compared video game players with people who didn't play video games on three visual search tasks．They found that the experienced players were better．"研究人员还将视频游戏玩家和没有玩视频游戏的人进行了比较，他们发现有经验的玩家发现事情的能力比不玩游戏的人快．故选B．
31．B 主旨大意题．文章主要讲述了玩电子游戏可以帮助人找到一些隐藏在其他事物中的东西，这也是锻炼自己视觉搜索能力的一种行为．作者通过科学家的实验进行举证，说明玩电子游戏也可能是有一定好处的．结合选项，故选B．

10．Alan Tong was the worst driver in town．He had an accident of some kind almost every week．
Alan lived with his mother．His mother was always worried about him．Every day she worried that police would appear to arrest him．This wasn't a foolish worry because they usually visited Alan's house about once a week to send a speeding ticket or to serve him notice to appear in court（法庭）．
Most of his accidents were caused by his carelessness．He drove through red lights．He turned left or drove at night without proper lights．He overtook other cars on hills．In short，there wasn't a traffic rule that Alan had not broken，and he had had so many accidents that it was a surprise that he was still alive．But luckily for Alan，he had never hurt anyone in his accidents or even gone to the hospital．
   Although Alan wasn't popular with the police，he was very popular with his lawyer．Alan's lawyer，Mr．Tsui，had earned a lot of money from Alan's cases and always felt very excited when he saw Alan coming into his office．
   One day Alan was working in the garage，painting his car when his mother walked in．"What are you doing？"his mother asked．
"Painting my car，"Alan replied．
"I can see that，"his mother said，"but why are you painting one side of the car red and the other side blue？""Because every time I have to go to court for a traffic crime，there are always two witnesses （目击证人）．"What color was the car？"the judge always asks，and the two witnesses always give the same answer．Well，in the future，one witness will say it was blue．Mr．Tsui will then say to the judge，"Your honor，the witnesses cannot even agree on th e color of the car involved in the accident．"And the judge will have to dismiss the case against me．

8．I know what you're thinking：pizza？For breakfast？But the truth is that you can have last night's leftovers in the morning if you want to．
I know lots of women who don't have breakfast，and they have many different excuses for doing it．Some say they don't have time，others think they're"saving"calories（卡路里），still others just don't like breakfast food．
But eating in the morning is very important when you're trying to lose weight．Eating just about anything from 300to 400calories would be better than nothing at all．
Breakfast is one meal I never miss，and the same goes for most weight loss success stories．Research shows that eating breakfast keeps you from overeating later in the day．Researchers found that those who don't have breakfast have a bigger chance of gaining weight than those who regularly have a morning meal．
So eat something in the morning，anything．I know plenty of friends who end up having no breakfast altogether，and have just coffee or orange juice．I say，try heating up last night's leftovers-it may sound crazy，but if it works for you，do it!I find if I tell myself，"You can always eat it tomorrow，"I put away the leftovers instead of eating more that night．Try it…you may save youself some pre-bedtime calories．And watch your body gain the fat-burning effects．
51．The word"leftovers"in Paragraph 1probably meansC．
A．pizza topped with fruit
B．things left undone

15．Can dogs and cats live in perfect harmony in the same home？People who are thinking about adopting a dog as a friend for their cats are worried that they will fight．A recent research has found a new recipe of success．According to the study，if the cat is adopted before the dog，and if they are introduced when still young （less than 6months for cats，a year or dogs），it is highly probable that the two pets will get along swimminly．Two-third of the homes interviewed reported a positive relationship between their cat and dog．
However，it wasn't all sweetness and light．There was a reported coldness between the cat and dog in 25% of the homes，while aggression and fighting were observed in 10% of the homes．One reason for this is probably that some of their body signals were just opposite．For example，when a cat turns its head away it signals aggression，while a dog doing the same signals submission．
In homes with cats and dogs living peacefully，researchers observed a surprising behavior．They are learning how to talk each other's language．It is a surprise that cats can learn how to talk‘dog'and dogs can learn how to talk‘Cat'．
What's interesting is that both cats and dogs have appeared to develop their intelligence．They can learn how to read each other's body signals，suggesting that the two may have more in common than we previously suspected．Once familiar with each other's presence and body language，cats and dogs can play together，greet each other nose to nose，and enjoy sleeping together on the sofa．They can easily share the same water bowl and in some cases groom （梳理） each other．
The significance of the research on cats and dogs may go beyond pets─to people who don't get along，including neighbors，colleagues at work，and even world superpowers．If cats and dogs can learn to get along，surely people have a good chance．
25．Some cats and dogs may fight whenA．
A．they misunderstood each other's signals
B．they look away from each other
C．they are cold to each other
D．they are introduced at an early age
26．What is found surprising about cats and dogs？B
A．They eat and sleep each other．
B．They learn to speak each other's language．
C．They observe each other's behaviors．
D．They know something from each other's voices．
27．It is suggested in Paragraph 4that cats and dogsC．
A．have common interests
B．have a common body language
C．are less different than was thought
D．are less intelligent than was expected
28．What can we human beings learn from cats and dogs？C
A．We should live in peace with animals．
B．We should know more about animals．
C．We should learn to live in harmony．
D．We should learn more body languages．

5．Many great basketball players had clever nicknames  （绰号），usually describing the player's overall style on the court （球场）．Below are some of the colorful nicknames among popular NBA players．
"Tiny"
Nate Archibald，at six feet one inch tall，was small for a basketball player．Still，Archibald used speed and his brains to control the court in the 14seasons that he played in the NBA．Interestingly，his nickname originated off the court：he was named after his father，"Big Tiny"．
"Magic"
Earvin Johnson was called"Magic"by a sportswriter who saw him playing basketball in one high school game．Johnson was a skillful player，often doing the unexpected，to the chagrin of his competitors and the delight of the audience．He also won a gold medal as part of the U．S．"Dream Team"in the 1992Summer Olympics in Barcelona，Spain．
"The Mailman"
Karl Malone earned his nickname because on the court he delivered consistently．Malone spent most of his career with the Utah Jazz，gaining a reputation as one of the best power forwards of all time．He also won two Olympic gold medals，as part of the U．S．"Dream Team"in the 1992Summer Olympics in Barcelona，Spain and in the 1996Summer Olympics in Atlanta，Georgia．
"The Iceman"
George Gervin made the most difficult shots look easy．He was also famous for keeping his cool in every game，playing in a relaxed way under pressure．Gervin，who played most of his 14years in the NBA with the San Antonio Spurs，was unequalled in many ways as a shooting guard．

12．One of the best-known proverbs must be"Early to bed，early to rise，making a man healthy，wealthy and wise"．The promise of health，wealth and wisdom to those who join the ranks of the early retirees and risers must be particularly appealing to many people in our modern society．There is no doubt that one of the greatest concerns（关心） of modern man is his health．It is estimated that in the United States $200billion is spent on health care each year．The medical field has grown into such a big business that it employs 4.8million people； and it appears that in many places，more staff is needed to meet the demands of the people who are concerned about their physical well-being．?
Much more interest has been shown in preventive medicine in recent years．This is probably due in part to the increasing costs of medical treatment，but the writings of such people as Dr．Kenneth Cooper have also played an important role．In his book Aerobics Dr Cooper communicated his message of the benefits（好处） of exercise so effectively that many other authors have followed in his trail，and literally millions of readers have put on their sports shoes and taken to the highways and byways of America．A recent survey showed that over 17 million people are jogging．Many of these are so serious that they have trained themselves to run the 26 miles and 385 yards of the hard and tiring marathons that are organized all over the country．The last time I was in Honolulu，I was greatly surprised to see hundreds of people，young and old，running for their lives，and I discovered many of them have run in the Hawaiian Marathon．?
Exercise has also become a major part of conversation．At a dinner party recently，the president of a bank asked me，"You look like a runner； how far do you run each day？"A few days later when I appeared on a national television show，the host suddenly asked me if I was a regular runner．On both occasions the conversation turned to the subject of exercise and I found，as I have found whenever I have traveled recently，that this is a subject of being on many people's minds．Of course，there are still many people who are less than enthusiastic about exercise．They appreciate the philosophy of Robert M．Hutchins who said，"Whenever the thought of exercise occurs to me，I lie down till it passes．"

32．The first paragraph suggests that medical workersA．
A．are in great need
B．make a lot of money
C．are concerned with their own health
D．like sports more than ordinary people
33．In the United States，medical treatment isD．
A．very effective
B．not enough
C．cheap
D．expensive
34．Aerobic is a book aboutB．
A．medicine
B．exercise
C．driving
D．marathon
35．The examples of conversation in the last paragraph are usedC．
A．to prove that people are tired of old conversation topics
B．to prove that the writer was a good runner
C．to show people's interest in exercise
D．to show the writer's love for travel．

9．Urban swans might be born with a daredevil gene that makes them less fearful of humans，compared with their rural colleagues．
A study has found swans living in cities tend to be bolder and it is at least partly determined by a gene called DRD4．Birds with this gene could therefore be better adapted to settling in more populated areas，while more timid（胆怯的）swans would escape to less inhabited regions．
It could help to explain why swans in public parks and on urban rivers have a reputation for being so aggressive towards humans-they are simply not afraid of us．
Biologists from some universities in Australia，tracked and collected blood samples from black swans living in two wetlands near cities．One group of swans lived in a recreational urban park，while the other occupied a waste-water processing site out of town．The two areas were less than 20 miles apart．Later，from 2011through 2013，the researchers started systematically scaring the swans at both sites．The researchers approached the birds and calculated how close they could get before they flew away．As expected，they noticed that while rural swans started flying away if a human was closer than 119 meters，the scientists could come as close to urban swans as 39 meters before taking off．
Analyses of the blood samples，in fact，showed that 83 percent of the less cautious swans presented the same genetic DRD4 variation（变异）while rural swans have different genetic makeups resulting in more wariness（谨慎，小心）．
The researchers conclude that swans with the bold variation of the gene might choose to live in urban environments，as they tend to be less bothered by human presence．

24．The underlined word in paragraph 1meansC．
A．timid
B．cautious
C．bold
D．stubborn
25．What's the difference between rural swans and urban ones？C
A．The rural swans carry more DRD4．
B．The urban swans are more friendly．
C．The urban swans are less scared of people．
D．The rural swans are aggressive towards humans．
26．What does DRD4 refer to？C
A．a kind of blood．
B．a kind of food．
C．a kind of genetic variation．
D．a kind of swan．
27．What does the 4^th paragraph mainly talk about？D
A．The living habit of swans．
B．The living environment of swans．
C．The contribution of the biologists．
D．The process and result of the research．
