In the past, man did not have to think about protection of the environment. There were very few people on the earth, and natural resources seemed to be unlimited.
Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this.
We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycle them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if all of us think about the problem, we will have a better and cleaner planet in the future.

American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.
The study, conducted by neuroscientists （神经学家）and psychologists from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day—over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal（能发出声音或语言的） than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic（超声波的） range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups幼崽were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.
“Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals.”
【小题1】From the second paragraph, we can learn that ________.
| A．women always speak more words than men |
| B．men and male rats have low levels of language protein |
| C．women and male rats have similar levels of Foxp2 |
| D．McCarthy isn’t the first to find females more talkative |
| A．paid attention to | B．related to | C．put pressure on | D．counted on |
| A．test which part of the brain is key to language in rats and humans |
| B．prove the levels of Foxp2 protein in humans and rats are different |
| C．determine the reason why female rats are more talkative than male rats |
| D．discover the association between Foxp2protein and vocal communication |
| A．Tests on humans and rats | B．Why women are the talkative sex |
| C．Sex differences in fussed over | D．Foxp2 protein determines oral ability |

Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
"I think we are knocking at the door of immortality(永生)," said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that’s a conservative estimate".
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology（纳米技术）make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years."
However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology(老龄学) Center. "At present people who could get to that point are not in good health at all."
【小题1】By saying "we are knocking at the door of immortality", Michael Zey means ________.
| A．they believe that there is no limit of living |
| B．they are sure to find the truth about long living |
| C．they have got some ideas about living forever |
| D．they are able to make people live past the present life span |
| A．people can live from 120 to 180 years |
| B．it is still doubtful how long humans can live |
| C．the human body is designed to last about 120 years |
| D．it is possible for humans to live longer in the future |
| A．a great push |
| B．the idea of living beyond the present life span |
| C．the idea of living from 200 to 300 years |

Google, the Internet search and mapping company, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives.
【小题1】What’s the main idea of the passage?
| A．An auto revolution is on its way. |
| B．Google has developed a driverless car. |
| C．The Carbot has passed its early testing stages. |
| D．Science fiction has turned into reality. |
| A．it uses radar, lasers and video cameras |
| B．it knows speed limits, traffic patterns and road maps |
| C．the computer has a better sense of direction than drivers |
| D．the software responds to emergencies faster than a human driver |
| A．it can drive all by itself |
| B．it can avoid any traffic accident |
| C．it doesn’t pollute the environment |
| D．it is the most fashionable car nowadays |

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
【小题1】A good title for this reading passage is______.
| A．Popeye the Sailor | B．The Truth About Spinach |
| C．A Mistake with Numbers | D．Folic Acid Makes You Strong |
| A．They thought spinach made them strong. |
| B．They thought Popeye was funny. |
| C．Spinach had a lot of iron. |
| D．People liked folic acid. |
| A．made Popeye strong |
| B．was a green vegetable |
| C．had less iron than other green vegetables |

Our culture is the system we use to build our identity. All living creatures are part of a culture. Even animals have a culture! So what is culture? It’s the way we behave in a group. It begins with each individual family. Within our families we do things to build relationships with each other. This can include routines for doing things. It also includes traditions. Traditions are activities that are repeated on a regular basis.
Culture is not limited to individual family groups. The real strength of culture is in larger community （社会）groups. These larger groups are called societies. Every society makes rules for itself. It decides how people should act in different situations. Some of these rules are written down. Some are just things that are automatically expected of all members of that society. Often, cultures can be identified（识别）by what the people believe. Cultures are also known by what they choose to include in their art. Sometimes a society forms around people who speak the same language. Cultures may also be known for their customs, including the foods they make and the things they do.
Our cultures help us understand who we are and what we believe. There are very strong emotions（情感）connecting us to our own society. Two different cultures may disagree on something, especially if they both feel strongly about it. When that happens, war is a common result. People are learning better ways to communicate with each other. The more we learn, the more we appreciate the differences in cultures.
【小题1】Which of the following is not true?
| A．Every society has its own culture. |
| B．Every one with an identity card has his own culture. |
| C．Animals have their cultures. |
| D．Culture and traditions are connected. |
| A．A religion that a certain people practice |
| B．Greetings sent to people we love during spring festival |
| C．Face-changing in Sichuan Opera |
| D．Someone’s personal habit of staying up very late |
| A．Modern societies have written down all the rules for behavior. |
| B．Plants themselves have no culture. |
| C．Disagreement between two societies always leads to war. |
| D．Strong emotions that connect us to our society should be got rid of. |
| A．cultural exchanges may help reduce the risk of war |
| B．all disagreements are caused by strong feelings |
| C．differences in culture always cause disagreements |
| D．people haven’t tried different ways to communicate |

A Korean wave is sweeping across China, with many Chinese women worshipping South Korean actors Kim Soo Hyun and Lee Min Ho as demigods (半神半人). Chinese netizens have always been divided over South Korean TV dramas, but there is no doubt that programs from the neighboring country are now enjoying a new round of popularity in China. And a big part of the credit for that goes to You Who Came From The Star, the South Korean TV series which is on the air now.
Top South Korean actors Jun Ji-hyun and Kim Soo Hyun recently earned a popularity rating of 24.8 percent in their country, considered strong by Nielsen Korea. You Who Came From The Star and The Heirs have been subjects of hot online discussions throughout Asia. Besides, the book, The Miraculous Journey of Edward Tulane, read by the hero in You Who Came From The Star was a hard-to-get item on Amazon for a while.
The two TV programs have several common elements: a tall, handsome, and rich hero who loves the heroine blindly and always protects her, and an equally handsome man madly in love with the same woman. Both programs portray the purity of love, which is expressed through a kiss or a warm hug. Perhaps that’s the secret of their success; perhaps people are still fascinated by Cinderella-type stories.
The growing wealth gap is a matter of social concern both in South Korea and China, and the challenges that young people face in their search for a better life might have prompted (激起) many ordinary girls to dream of marrying rich, caring men. This is precisely what the popular South Korean TV dramas portray. In fact, South Korean TV dramas are tailored to meet the market’s demands.
In contrast, Chinese TV screens are flooded by knock-off (山寨) or poorly made soap operas. There are too many Chinese TV dramas that are either of the stereotyped (刻板的) war theme or just blindly copy foreign programs. The lack of good stories has resulted in loads of TV series on time travel or fights in the harems (后宫) of Qing Dynastyemperors. These, in short, are the pain of Chinese TV productions.
The shooting for South Korean productions generally starts when the scripts (脚本) are just one-third ready. Many popular productions have their own websites, where scriptwriters post part of the finished scripts, inviting viewers to leave messages, discuss the plot and come up with suggestions for future events. This not only keeps viewers’ interest in the TV dramas alive, but also helps scriptwriters and directors make changes to the storylines to suit the audience’s demand.
Hopefully, the innovation-induced (创新引导的) success of South Korean TV programs will prompt Chinese TV drama makers to think up new ideas and abandon their bad practice of copying foreign productions in order to attract more viewers at home, and possibly abroad.
【小题1】The main point the author emphasizes in this passage is ________.
| A．why Korean actors are more popular than Chinese actors |
| B．how the three Korean actors became famous around East Asia |
| C．what modern TV dramas need is not copying foreign programs but innovation |
| D．the Cinderella-type stories are an ever-lasting theme people are fascinated with |
| A．The celebrity effect is powerful. |
| B．Drama stars are the best advertisements. |
| C．Rich and handsome heroes in dramas usually love reading. |
| D．A successful drama generally originates from a good novel. |
| A．drama stars must be tall, rich and handsome or beautiful |
| B．scriptwriters should choose the appropriate themes for all viewers |
| C．drama producers have creative ideas to adapt to viewers’ interest and demand |
| D．people’s concerns such as wealth gap both in Korea and China are taken good care of |
| A．Abandoning copying foreign productions is the only way to attract viewers. |
| B．The Chinese TV drama makers should follow in the footsteps of the Koreans. |
| C．It’s hard to predict what the future TV dramas in China and Korea will be like. |
| D．A bright future of Chinese TV dramas can be expected prompted by the Koreans. |

Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.
【小题1】 What surprised the scientists a few years ago?
| A．Fatigue toxins could hardly be found in a laborer’s blood. |
| B．Albert Einstein didn’t feel worn after a day’s work. |
| C．The brain could work for many hours without fatigue. |
| D．A mental worker’s blood was filled with fatigue toxins. |
| A．Challenging mental work. | B．Unpleasant emotions. |
| C．Endless tasks. | D．Physical labor. |
| A．He agrees with them. | B．He doubts them. |
| C．He argues against them. | D．He hesitates to accept them. |
| A．have some good food. | B．enjoy their work |
| C．exercise regularly | D．discover fatigue toxins |
