How long do you want to live? How many years might be added to a life? 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.（壽命）
“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(保守的估計)."
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(納米技術(shù)) 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 research into ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say the 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 Poon, director  of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."

The World's Largest Insect .This giant insect can be used as a toy.
A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world.
The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.
African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.
小題1: The African Goliath beetle is _______. 
A．the world's largest insect
B．a(chǎn) toy used in many parts of the world
C．the only insect found in Africa
D．the world's smallest insect
小題2:What do African children often use the Goliath beetle as?
A．a(chǎn) tool.B．a(chǎn) toy. C．harmfull insects.D．Good animals.
小題3:We know the Goliath beetle is a true insect because it _______. 
A．makes a whirring sound when it flies B．has both soft and hard wings
C．has six legs and a body with three parts D．can fly
小題4:When flying, the Goliath steers by_______. 
A．turning its soft back wings
B．twisting and turning its hard front wings
C．twisting and turning its legs
D．twisting and turning its whole body

Does your child struggle in school? Is he or she afraid of reading out loud, writing an essay, or working out a math problem? While every kid has trouble with homework from time to time, if a certain area of learning keeps going wrong, it might show a learning disorder. Learning disorders, or learning disabilities, are a general term for a wide variety of learning problems.
A learning disability is not a problem with IQ or motivation (動機). Kids with learning disabilities aren’t lazy or slow. In fact, most are just as smart as everyone else. Their brains are just wired (裝電線) differently. Simply put, children and adults with learning disabilities see, hear, and understand things differently. This difference affects how they receive and process (處理) information. This can lead to trouble in learning new information and skills, and putting them to use.
It can be tough to face the possibility that your child has a learning disorder. No parents want to see their children suffer. You may wonder what it could mean for your child’s future, or worry about how your kid will make it through school. But the important thing to remember is that most kids with learning disabilities are just as smart as everyone else. They just need to be taught in ways that suit their unique learning styles.
It’s not always easy to tell whether a child has learning disabilities, for learning disabilities look very different from one child to another. One child may struggle with reading and spelling, while another loves books but can’t understand math. Still another child may have difficulty understanding what others are saying or communicating loud. However, some warning signs are more common than others at different ages. If you’re aware of what they are, you’ll be able to catch a learning disorder early and quickly and take steps to help your child as quickly as possible.
小題1:From the passage, we can infer that_______.
A．students with learning disabilities look quite different from normal students
B．students with learning disabilities can’t do well in their studies
C．only few students with learning disabilities are as clever as normal students
D．it is quite possible for a students with learning disabilities to succeed in their studies
小題2:What is the main idea of the passage?
A．Learning about learning disabilities.
B．How to prevent learning disabilities.
C．Ways to identify learning disabilities.
D．Different learning disabilities.
小題3:What will be most probably discussed following the Paragraph 4?
A．Some ways which help parents teach their children with learning disabilities better.
B．Some suggestions on how to get along with their children with learning disabilities.
C．Some parents may have difficulties in helping their children with learning disabilities.
D．Some warning signs which show that a child may have learning disabilities.

People have always been dreaming of going to the moon. As long as the year 1901, H. G. Wells, an English writer, wrote a book vividly describing a trip to the moon. On landing there, the explorers discovered that the moon was full of underground cities. Words failed to express their surprise when they spotted so many “moon people”. The “moon people” felt even more surprised. “Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”
H. G. Wells could only imagine a travel to the moon. In 1969, human beings really left their footsteps on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Channel”, a tunnel connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太陽能穹頂) would cover the whole city.
Supporters of underground development argue that building down rather than building up is a good way to use the earth’s space. The space, they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ “moon people” would second it. Would you?
小題1:The explorers in H. G. Well’s story were surprised to find that the “moon people”     .
A．knew so much about the earth
B．understood their language
C．lived in underground cities
D．were advanced in technology
小題2:What does the underlined word “it” (paragraph 2) refer to?
A．Discovering the moon’s inner space
B．Using the earth’s inner space
C．Meeting the “moon people” again
D．Traveling to outer space
小題3:What sort of underground systems are already in place?
A．Offices, shopping areas, power stations.
B．Tunnels, car parks, shopping areas.
C．Gardens, car parks, power stations.
D．Tunnels, gardens, offices.
小題4: We can learn from the text that     .
A．H. G. Wells once went to moon himself.
B．Underground cities are more comfortable.
C．The solar dome is a necessary part of underground cities.
D．More underground systems will be in place in 2013.
小題5:What would be the best title of the text?
A．Alice Cities — cities of the future
B．Space travel with H. G. Wells
C．Enjoy living underground
D．Building down, not up

“I don’t speak English”-these are the first words I learned when I came to America. Soon I was able to pronounce the four words clearly, and said them whenever an American tried to talk to me. This answer was very effective（有效的）at ending our conversation and saving me from another uncomfortable situation, or I would have to communicate in a language that I was not familiar with.
Before coming to the States, I thought I knew English pretty well. But the truth is that the grammar and vocabulary-based English that is taught in schools overseas（海外的）is not the English people speak in America.
But fear not! Once you are in America, you can immediately begin to bridge the gap（彌補差距）between the learned English that you already know, and the spoken English that is all around you. To do this, first of all, it is important not to fear when you realize that you may not be as prepared for daily communication as you thought. For me, as soon as I stopped worrying about my accent and started speaking, I made rapid progress. Often the people didn’t notice my mistakes because they were so glad to finally be able to communicate with me.
Another good idea is to listen carefully and pay attention to the way in which ideas are expressed. For example, if you are working hard and you want to stop working and rest for a little while, you can either say “I would like to stop working and rest for a while” or “I want to take a quick break from work.” The first sentence, I quickly learned, sounds dry and too formal for any kind of communication, while the second is an idiom（成語）that is widely used in American English conversation.
Finally, use what you already know---the vocabulary, the grammar and the spelling. Try to use these into the spoken language for more impressive and accurate（精確）speaking results.
小題1:What’s the main idea of this passage?
A．You’d better say “I don’t speak English” in the USA.
B．How you can improve your spoken English in the USA.
C．Idioms are widely used to express your ideas in the USA.
D．Listening is the best way to improve your spoken English in the USA.
小題2:At first the writer preferred to use the sentence “I don’t speak English” to       .
A．a(chǎn)dmit he is a foreigner
B．save much time for himself
C．prevent himself from being laughed at
D．a(chǎn)void getting upset in communicating with others
小題3:What’s the problem with the English taught outside the English-speaking countries?
A．It is quite different from what the natives speak.
B．It is taught in boring and wrong grammar.
C．It has nothing to do with English.
D．It has too small a vocabulary.
小題4:When did the writer make rapid progress in spoken English?
A．As soon as he paid attention to the way Americans spoke.
B．The minute he found what has been learned useless.
C．The moment he got rid of the fear of speaking.
D．Immediately he arrived in the USA.
小題5:All the following are tips given buy the writer EXCEPT “       .”
A．speaking bravelyB．listening carefully
C．using what you have learnedD．making few mistakes

All over the world people enjoy sports, Sports help to keep people healthy and happy, and to live longer.
Many people like to watch others play games. They buy tickets or turn on their TVs to watch the games. Often they get very excited when “their” player or team wins.
Some sports are so interesting that people everywhere go in for(參加) them. Football, for example, has spread(展開)around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy! And think of people in cold countries. Think how many love to skate or ski (滑雪) in Japan, Norway or Canada.
Some sports or games go back thousands of years, like running or jumping. Chinese wushu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. Water-skiing is one of the newest in the family of sports.
People from different countries may not be able to understand each other, but after a game together they often become good friends. Sports help to train a person’s character. One learns to fight hard but fight fair, to win without pride and to lose with grace(勝不驕，敗不餒).

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(風(fēng)車) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(碾碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.
小題1:From the text we know that windmills________.
A．were invented by European armies
B．have a history of more than 2,800 years
C．used to supply power to radio in remote areas
D．have rarely been used since electricity was discovered
小題2:What was a new use for wind power in the late 19th century?
A．Sailing a boat.
B．Producing electricity.
C．Grinding wheat into flour.
D．Pumping water from underground.
小題3:One of the reasons wind was rediscovered in the 1970s is that_______.
A．wind power is cleaner
B．it is one of the oldest power sources.
C．it was cheaper to create energy from wind
D．the supply of coal and gas failed to meet needs
小題4:What would the author probably discuss in the paragraph that follows?
A．The advantages of wind power.
B．The design of wind power plants.
C．The worldwide movement to save energy.
D．The global trend towards producing power from wind.

A victim of climate change
A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July．
The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals．"From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it． However, the animal was reduced to skin and bones and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone．"
Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals． That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April．
Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change．
The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．
小題1:How did Stirling know the reason for the death of the polar bear?
A．By the food he ate．B．By doing further experiments．
C．By observing other polar bears．D．By his lying position in death．
小題2:The underlined word "vulnerable" probably means _____．
A．easily hurtB．difficult to hunt
C．dangerousD．a(chǎn)mazing
小題3:What is the author's attitude to the incident?
A．Favorable．B．Uncaring．
C．Doubtful．D．Concerned．
小題4:Where does this text probably come from?
A．A novel．B．A guidebook．
C．A news report．D．An advertisement．

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (尋求刺激) or imperative (沖動) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”
小題1:The research led by Sanbonmatsu indicates that people who multitask __________.
A．seek high productivity constantly
B．prefer handling different things when getting bored
C．a(chǎn)re more focused when doing many things at a time
D．have the poorest results in doing various things at the same time
小題2:When Sanbonmatsu and his colleagues conducted their research, they __________.
A．a(chǎn)ssessed the multitasking ability of the students
B．evaluated the academic achievements of the students
C．a(chǎn)nalyzed the effects of the participants’ tricky mental tasks
D．measured the changes of the students’ understanding ability
小題3:According to Sanbonmatsu, people multitask because of their __________.
A．limited power in calculation
B．interests in doing things differently
C．inability to concentrate on one task
D．impulsive desire to try new things
小題4:From the last paragraph, we can learn that multitaskers usually __________.
A．drive very skillfully
B．go in for different tasks
C．fail to react quickly to potential dangers
D．refuse to explain the reasons for their behavior
