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．"

19．When you buy cooking oil in the supermarket，you may notice that some brands are labeled as"GM （genetically modified 转基因）-free"．So，what is genetic modification？Are GM foods safe？
These questions have been put back into the public attention recently．On Nov 19，the Food and Drug Administration （FDA） in the US announced that it had approved the AquAdvantage salmon to go on the market，making it the first GM animal to be approved as food anywhere in the world．
GM foods are plants or animals that have been given a gene from another plant or animal to make them stronger in some way．The AquAdvantage salmon contains a gene from another type of salmon that makes it grow faster．
Although the FDA has said"food from the fish is safe to eat"，some believe that scientists can't completely understand the potential health risks of GM foods，simply because they're so new．Others worry that the fish could escape into the wild and cause ecological problems．
GM crops have experienced the same public argument，even though GM technology cuts down on the use of pesticides（杀虫剂） on crops and increases output．
While GM animals are new，GM crops have already appeared on our plates：A total of 28countries in the world including the US，Brazil and India planted 181.5million hectares （1.815million km2）of GM crops in 2014，according to the International Service for the Acquisition of Agri-biotech Applications．In China，we grow GM cotton and papaya and import GM soybeans，corn，rape，cotton and beets from abroad．
Due to safety worries，many countries have regulations for producing and selling GM foods．
In European Union countries，each GM food must be approved before it can be used．This process can take up to 17months．The origin of all GM foods must also be traceable，and all food with a GM content of more than 0.9percent must also be labeled，according to EU website europaeu．
The US is less strict about GM foods．According to FDA regulations，companies introducing new GM foods to the market should report them at least 120days before release．The labeling is voluntary，except that a product cannot be labeled as"GM-free"if genetically modified materials are used．
In China，GM foods can only be produced after strict tests by the Ministry of Agriculture and it's sure that they are safe．All food that is made from GM crops or contains GM ingredients must be clearly labeled on the wrapper．

18．Leon McCarthy，12，was born without fingers on his left hand．That didn't stop him from being able to do many tasks．But Leon could not grasp more than one object at a time．So Leon's father，Paul，created a Prosthesis（假肢），using a 3D printer．Now Leon has fingers that open and close．"It was a do-it-yourself，father-and-son adventure，"says Paul．
When Leon was a baby，his doctor advised his parents not to give him a prosthetic hand until he was in his early teens．"The doctor said Leon should first learn to get full use out of the hand he was born with，"says Paul．As Leon got older，his father looked into buying a prosthetic hand，which can cost as much as 30，000．Paul found a more affordable solution．
One day，Paul discovered a video on the Internet about Robohand，a prosthesis created with a 3D printer．He downloaded the free instructions and called Robohand's creators for advice．They told him all he needed was a 3D printer-which costs around 2，000-and some materials．
Luckily，Leon's school had recently purchased a 3D printer and it offered to help Paul build the hand for Leon．"We used a soccer shinguard（护胫），cardboard，and tape．They cost about 10，"says paul．
With his new hand，Leon can do things better．"I can help my mom more，because now I can carry two grocery bags，"he says．
Leon's father has already built several hands for Leon．Leon helps design each one．He says there's one thing in particular that he wants to do with a future prosthesis．"The goal，"he says，"is to be able to tie my shoelaces（鞋带）．"

16．A new survey conducted by the National Geographic Society （NGS） shows that although consumers in many countries are adopting environmentally-friendly behavior，others live in wasteful cultures of consumption．
The 2014online survey of 18，000people in 18countries judged environmental attitudes and habits-and their sustainability-when it came to housing，transportation，food and consumer goods．
1．Some consumer behavior is improving．
In half the countries surveyed，people acted in more environmentally-friendly ways than they had in 2012．For example，Russians are using more public transportation and British consumers are buying more green electricity．
But some countries reported that people's habits were less sustainable than in the previous survey．Around 68percent of Germans drink bottled water daily，and Canadians are among the most likely to own at least two car or trucks．
2．Anxiety about the environment is growing．
A slim majority of consumers-51percent-agree that global warming will negatively affect their own lives．Latin Americans are the most concerned，with more than three in four Brazilians convinced that climate change will impact them personally．
3．Americans resist going green．
Nearly one in four American households owns four or more TVs．Americans are also among the most likely to avoid paying extra for environmentally-friendly products，and they consume more packaged and processed food than people in most other countries．And since the 2012survey，more Americans are saying that they view owning a big house as an important goal in their lives．
4．The least green feel the least guilt．
As in past surveys，the worst offenders express the least guilt about the size of their environmental footprint．British，German and Swedish consumers not only feel the least regret but also are the most likely say they won't change their ways．
5．Repairing，reusing and recycling are on the rise．
Majorities in 17of the 18countries say they'd rather repair than replace a broken item，with Chinese and German consumers the most likely to fix something and Japanese consumers the least likely．American and French consumers are the most likely to buy used items； Canadian，British，and Australian consumers are the biggest recyclers．
29．The author's purpose in mentioning Germans isD．
A．to say that dinking bottled water is not environmentally-friendly at all
B．to point out that bottled water is a less sustainable product
C．to emphasize that Germans should change their habits
D．to explain that people in some countries have some less sustainable habits
30．Which of the following is TRUE about the survey results？B
A．Japanese consumers are among the biggest recyclers．
B．The majority of Brazilians believe climate change will affect their lives．
C．Chinese and Canadian consumers like to repair broken items．
D．Used items are popular with French and British consumers．
31．What can we learn about Americans from the passage？B
A．Three in four American families don't have TV sets．
B．Many of them dream of owning a big house．
C．They think green products are too expensive．
D．They prefer packaged and processed food to health food．

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

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．

14．Twelve years ago，Rachel Miller was lost when it came to her son John．The 7-year-old was seriously disabled because of his autism（自闭症）．Unable to speak，he withdrew from people at school and，worse still，from his family．
In March 2003，Miller was introduced to Jeff Hancock，a one-on-one therapist（治疗师）for people with autism．Hancock was hired to be John's companion．The two would go people-watching at the mall in Stuart，Florida，on the weekends．Hancock chatted throughout their trips，even though John couldn't talk back．
Their relationship developed when Hancock introduced John to the Special Olympics in Martin County．Whenever John was running or bing active，he was smiling．When John turned 12，Hancock introduced him to track at the Special Olympics．For the first three years，the air just observed the sport by watching practices and events．Hancock worked daily with John，showing him everything，including where to sit，stand and walk，so he would understand the flow of the events．
In May 2014，John's training brought him to the Special Olympics State Summer Games in Orlando．The 18-year-old was competing in the 800meters and the 110-meter hurdles．
As the 800was setting up，Miller remembered，she pressed her face against the fence，anxiously waiting for John to compete．But as soon as the race started，her fears melted away，and all Miller saw was an athlete，her athlete．"I just wanted to see the best performance．It seemed much more significant than whether he would ever speak or respond to me，"she said．
John ended up winning the gold medal for the 800．Sports completely changed John，and Miller said that is because of Hancock．"A person with a disability can feel hopeless and isolated（孤独的），and I think that can happen to parents，too．Jeff probably saw that with us，"Miller said，thinking back to when Hancock first met their family．

A terrible earthquake strike Wenchuan in 2008．Many people lost their lives and homes．After the earthquake，under a fallen building a mother as well as her baby were found by some soldiers．When the soldiers were ready to taking them away，they surprised to find the baby in the mother's arms still alive．The baby was sleeping but wasn't hurt at all．Between the dead mother and the living baby，there was a cell phone with a short message on the screen．It read，"Don't worry，my baby．Mom is for you．If you can survive，don't forget that I love you．"
The story moved me deep．I couldn't hold back my tears when I read these word．One is great if he love others when he is in the danger．

12．Mrs．Packletide intended to shoot a tiger．Not that the desire to kill had suddenly come to her，or that she felt she would leave India safer with one wild beast less．It was because Loona Bimberton had recently taken a plane to the forest and killed a tiger，and the newspapers showed photographs of Loona Bimberton with a tiger-skin on．In a world supposed to be moved by hunger and by love，Mrs．Packletide's movements were largely governed by dislike of Loona Bimberton．
Circumstances proved favorable．Mrs．Packletide had offered a thousand rupees （印度卢比） for the opportunity of shooting a tiger without risk or effort，and it happened that an old tiger was frequently coming to a neighboring village at night．He was so old that he couldn't kill animals in the wild and just satisfied his appetite to the smaller household animals．The villagers were eager to earn the thousand rupees； children were posted night and day in the jungle to watch the tiger，and the cheap goats were left about to keep him from going elsewhere．The one great fear was that he should die of old age before the day of Mrs．Packletide's shoot．
The great night arrived．A platform had been built in a tree，on which sat Mrs．Packletide and her paid companion，Miss Mebbin．A goat with a loud bleat （咩咩叫） was tied down at the correct distance．With an accurate gun，they waited for the coming of the tiger．
"I suppose we are in some danger？"said Miss Mebbin．
She was not actually nervous about the wild beast，but she was unwilling to perform a bit more service than she had been paid for．
"It's a very old tiger．It couldn't spring up here even if it wanted to．"said Mrs．Packletide．
Their conversation was cut short by the appearance of the old tiger．He saw the goat，and lay on the earth for a short rest before attacking．
The gun fired very loudly，and the great yellow beast jumped to one side and then rolled over in the stillness of death．In a moment a crowd of excited villagers appeared on the scene，and their shouting carried the glad news to the village．
It was Miss Mebbin who found that the goat was dying from a bullet-wound，while no wound could be found on the tiger．Evidently the wrong animal had been hit，and the tiger had died of heart-failure，caused by the sudden loud noise of the gun．Mrs．Packletide was annoyed at the discovery； but anyway，she owned a dead tiger，and the villagers，anxious for their thousand rupees，gladly accepted the fiction that she had shot the tiger．And Miss Mebbin was a paid companion．Therefore Mrs．Packletide faced the cameras with a light heart，and her pictures appeared on the newspapers of England and America．As for Loona Bimberton，she refused to look at a newspaper for weeks，and was in a depressed emotion for quite some time．
Mrs．Packletide's tiger-skin was inspected and admired by the neighbors，and Mrs．Packletide went to the Costume Ball in the character of Diana （狩猎女神）．
"How amused everyone would be if they knew what really happened，"said Miss Mebbin a few days after the ball．
"What do you mean？"asked Mrs．Packletide quickly．
"How you shot the goat and frightened the tiger to death，"said Miss Mebbin，with her unpleasant laugh．
"No one would believe it，"said Mrs．Packletide，her face changing color1rapidly．
"Loona Bimberton would，"said Miss Mebbin．
Mrs．Packletide's face settled on greenish white．"You surely wouldn't give me away？"she asked．
"I've seen a weekend cottage near Dorking，"said Miss Mebbin，"six hundred and eighty．Quite a bargain，only I don't happen to have the money．"
Miss Mebbin possessed the pretty weekend cottage．Mrs．Packletide lost interest in animal-hunting．
"The extra expenses are so heavy，"she said to inquiring friends．
