Futurologists predict that life will probably be very different in 2050.
TV channels will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots — they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere — in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there are devices（設備）that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes（基因）. Scientists have already produced clones of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
小題1:We can learn from the passage that some big companies prefer robots to human workers, because human workers __________.
A．often ask for more pay
B．can work 24 hours a day
C．a(chǎn)re not clever enough
D．a(chǎn)re often late for work
小題2:The underlined word “conquered” in Paragraph 5 most probably means ________.

A．few diseases will attack people by 2050
B．there will be no blind and deaf people by 2050
C．medical technology will be more effective by 2050
D．devices are connected directly to the brain to help people hear
小題4:What is the author’s attitude towards the cloning technology?
A．The author does not support the use of cloning technology.
B．The author thinks human cloning is impossible.
C．The author does not really support the idea of human cloning.
D．The author is quite excited about human cloning.
小題5:According to the passage, which of the following can be realized today?
A．Read newspapers on a computer.

Most people believe they don’t have much imagination. They are    11   . Everyone has imagination, but most of us, once we become adults, forget how to   12  it. Creativity isn’t always  13 with great works of art or ideas. People at work and in their free time   14   think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.
　　Making connections. This technique involves taking   15  ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words  16  with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the   17 to the job you have to do. So imagine you want to buy a friend an original   18  ; you could buy him tickets to match or take him out for the night.
　　NO limits! Imagine that normal limitations don’t   19  . You have as much time /space / money, etc. as you want. Think about your goal and the new  20  . If your goal is to learn to ski,    21  , you can now practise skiing every day of your life (because you have the time and the money). Now   22   this to reality. Maybe you can practise skiing every day in December, or every Monday in January.
Be someone else! Look at the situation from a    23  point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the  24   in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their    25 . The best fishermen think like fish!

Mobile phones are an important business tool for farmers in rural areas．But they also put a valuable educational tool in their hands．
The University of Illinois in the United States has a project called SAWBO—Scientific Animations Without Borders．It produces educational videos that can be downloaded to cell phones．The goal is to help people in developing countries improve their lives．
One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops．The process starts with sorting and drying the neem fruits．Then let the fruit dry in the sun for about three or four days, until they become brown．Using a mortar（碾槌） and stick, the fruits are slightly pounded to remove the shells from the fruits without breaking the seed inside．
The videos use computer animation（動畫）．Some of the animated characters are a little funny looking-like a farmer with a long nose．But the subjects are serious, including a health video on preventing cholera（霍亂）．Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood．He says, “The information is digested in such a way that in two minutes, we can transmit a complex idea．”
The researchers tested the seven-minute video on seven mobile phones．They wanted to see if people would share the video using Bluetooth wireless technology．With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the internet．As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages．" This is just incredible impact," said Francisco Seufferheld．
The team has made a few videos so far．These are available in a total of eighty languages, dialects and accents．Professor Barry Pittendrigh says there are plans for more videos later this year．
小題1:What is the text mainly about?
A．A best-selling mobile phone
B．A valuable educational project for farmers
C．United States support for developing countries
D．A new type of scientist –farmer relationship
小題2:The SAWBO program is introduced in order to ____．
A．raise farmers’ standard of living
B．do some research on mobile phones
C．develop farmers’ practical skills
D．help farmers prevent insect damage to crops
小題3:The biggest advantage of the program is that it______．
A．includes health video on preventing cholera
B．can be passed to farmers using Bluetooth technology
C．can be used to sort and dry the neem fruits
D．is easy for farmers to understand
小題4:Which of the following words can best take the place of the word “ pound” in the 3rd paragraph?

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough，the answer to both these questions is yes. To some extent（程度）our intelligence is given to us at birth，and special education can never make a genius(天才) out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts can be supported in a number of ways.
It is easy to say that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins, they  will very likely be as intelligent as each other. Relations like brothers and sisters，parents and children，usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine that now we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.
小題1:By using the example that two people closer in blood relationship are closer in intelligence that writer wants to prove    _    .
A．intelligence can be developed by environment
B．intelligence is given at birth
C．intelligence can be developed by experience
D．education plays an important part in the development of education
小題2:A child who lives in rich and varied surroundings turns out higher in intelligence because ________.
A．his family is rich and therefore can afford to develop his intelligence
B．he can break the limits of intelligence fixed at birth
C．his family is rich and provides him with various healthy food
D．these surroundings are likely to help him reach the limits of their intelligence
小題3:In the second paragraph “if we take two unrelated people at random from the population．．．” means “if we ____．”
A．choose two persons who are relative
B．take out two different persons
C．choose two persons with different intelligence
D．pick any two persons
小題4:The best title for this passage might be __________.        
A．Birth and EnvironmentB．Intelligence
C．The Answer to a QuestionD．Intelligence and Education

Should e­cigarettes (electronic cigarettes) be a new choice for the smokers trying to get rid of the habit? Reactions from Americans are mixed．More than half of the people questioned in a survey think e­cigarettes should be controlled by the US Food and Drug Administration，but 47 percent believe the e­cigarettes should be available to the smokers who want to quit．
“In the hunt for a safer cigarette，e­cigarettes are becoming a popular choice among those either trying to quit or looking to replace standard tobacco smoke with an alternative that manufacturers claim to be safer，” Zogby International，which conducted the survey，said in a statement．
About half of the 4,611 adults who took part in the survey had heard about e­cigarettes，which are battery­powered，or rechargeable cigarettes that vaporize a liquid nicotine solution．They do not produce smoke but a water vapor without smell．Sold mostly on the Internet，e­cigarettes were first made in China．
Last year the World Health Organization (WHO) warned against using e­cigarettes，saying there was no evidence to prove they were safe or helped smokers break the habit．The WHO said people who smoke e­cigarettes breathe in a fine fog of nicotine into the lungs．
Nearly a third of people questioned in the survey think that e­cigarettes should be allowed in places where smoking is forbidden，because they don’t produce smoke，but 46 percent disagree．Men who were aware of the availability of e­cigarettes were more likely than women to say they should be a choice available to smokers who want to quit．Young people，aged 18－29，and singles were the groups most open to trying e­cigarettes．Smoking is the single largest cause of preventable death worldwide，according to the WHO．
小題1:What can we learn from Paragraph 1?
A．American smokers ought to try e­cigarettes．
B．Americans have different opinions about e­cigarettes．
C．Every kind of cigarettes should be forbidden in America．
D．Most of the Americans don’t like e­cigarettes．
小題2:According to Zogby International，e­cigarettes ______．
A．a(chǎn)re much safer than common cigarettes
B．a(chǎn)re popular among people who want to quit smoking
C．will take the place of traditional cigarettes
D．a(chǎn)re produced in a safer way by manufacturers
小題3:What do we know about e­cigarettes from the passage?
A．Most Americans are familiar with them．
B．They are a good choice as there is no nicotine．
C．They produce a water vapor that can’t be seen．
D．Most people buy them on the Internet．
小題4:What’s the attitude of the WHO towards e­cigarettes?

Learning a Second Language
Some people learn a second language easily. Others have trouble learning a new language. How can you help yourself learn a new language, such as English? There are several ways to make learning English a little easier and more interesting.
The first step is to feel positive about learning English. If you believe that you can learn, you will learn. Be patient. You do not have to understand everything all at once. It is natural to make mistakes when you learn something new. We can learn from our mistakes. In other words, do not worry about taking risks.
The second step is to practice your English. For example, write a diary every day. You will get used to writing it in English, and you will feel comfortable expressing your ideas in English. Several weeks later, you will see that your writing is improving. In addition, you must speak English every day. You can practice with your classmates outside class. You will all make mistakes, but gradually you will become comfortable communicating in English.
The third step is to keep a record of your language learning. You can write this in your journal. After each class, think about what you did. Did you answer a question correctly? Did you understand something the teacher explained? Perhaps the lesson was difficult, but you tried to understand it.
You must be positive about learning English and believe that you can do it. It is important to practice every day and make a record of your achievements. You will enjoy learning English, and you will feel more confident in yourself.

The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage(短缺)seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.
小題1:What is most likely to be discussed in the paragraph that follows?
A．Ways to reduce the costs of building dams.
B．Steps to improving water use management.
C．Measures to deal with worldwide water shortages.
D．Approaches to handling the pressure on water supply.
小題2:From the first two paragraphs we learn that________.
A．much of the world's water is available for use
B．people in high rainfall countries feel lucky
C．the costs of water redistribution should be considered
D．water can be easily carried through pipes across the world
小題3:The text is mainly about________.
A．water supply and increasing population
B．water shortages and environmental protection
C．water redistribution and wildlife protection
D．water use management and agriculture

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds (揮發(fā)性化合物) —— chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from such volatile compounds to attract insects such as bugs and bees.
Plants can also discover  volatile compounds produced by other plants. A tree under attack by hungry insets, for instance, may give off these chemicals in order to let other trees know about the attack. In response, the other trees may send off their chemicals to keep the bugs away —— or even chemicals that will attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical sensor (傳感器) called an “electronic nose”. The “e-nose” can tell such compounds as plants make. When plants are attacked, scientists say, the e-nose could help quickly decide whether plants are being eaten by insects. But today, the only way to spot such insects is to inspect individual plants by observing them. This is a challenging task for managers of greenhouses, including those that can house thousands of plants. The research team is working with an e-nose that can recognize volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds based on the interactions (相互作用), and then the e-nose will give off electronic signals that the scientists can analyze by using computer software.
To test the e-nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all being common greenhouse crops. Then scientists collected samples of the air around damaged leaves from each type of crop. These plants had been damaged either by insects or by scientists who made holes in the leaves with a hole punch (打孔器).
The e-nose, it turns out, can identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage —— by insects or with a hole punch —— had been done to the tomato leaves.
With some fine-tuning (微調(diào)), a device like the e-nose can one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this can also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, India, who studies smells of flowers and plants. Hopefully, scientists believe, the device can bring large benefits to greenhouse managers in the near future.
小題1:We learn from the text that plants communicate with each other by ______.
A．making some sounds
B．waving their leaves
C．producing some chemicals
D．sending out electronic signals
小題2:What did the scientists do to find out if the e-nose worked?
A．They fixed 13 sensors inside the device.
B．They presented it with all common crops.
C．They collected different damaged leaves.
D．They do tests on damaged and healthy leaves.
小題3:According to the writer, the most amazing thing about the e-nose is that it can ______.
A．pick out ripe fruits quite expertly
B．spot the insects in a very quick way
C．tell different damages to leaves
D．recognize unhealthy tomato leaves
小題4:We can infer from the last paragraph that the e-nose ______.
A．is unable to tell the smell of flowers
B．is not yet tested in greenhouses
C．is designed by scientists at Purdue
D．is helpful in killing harmful insects
