Will life in the future be better, worse or the same as now? Futurologists（未來學家）predict that life will probably be very different in 2050.
First of all, it seems that TV channels will have disappeared by 2050. A computer will send the program directly to the television. On TV screen appear holograms（全息圖）, which are pictures with certain height, width and depth. We will be able to see, smell and touch the things that we see on television.
Water has become one of our most serious problems. Agriculture is changing and people are growing more fruit and vegetables to export. Demand for water will increase ten times in 2050. Some futurologists predict that water will be the cause of war if we don’t act now.
In transport, cars will run on new fuels and go very fast. A car will have computers to control its speed and there won’t be any accidents. On the other hand, space planes will take people around the earth in about three hours. People will fly from Los Angeles to Tokyo by space plane in just half an hour.
In the field of technology, robots will have replaced people in factories. By 2050, we will see robots everywhere. They do not ask for pay rises or go on strike, and they work 24 hours a day. 
Medicine technology will have conquered many diseases by 2050; we will be able to help blind and deaf people see again and hear again. Scientists have discovered how to control genes. They have already produced clones of animals and will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. If you want all this to come true, you should study science and technology hard.

Nothing succeeds like confidence. When you are truly confident, it radiates from you like sunlight, and attracts success to you like a magnet.  Besides, those who are self-confident can in turn inspire confidence in others: their audience, their peers, their bosses, their customers, and their friends. And gaining the confidence of others is one of the key ways in which a self-confident person finds success.
So how can we build a sense of self-confidence and prepare ourselves on the way to success?
First, do what you believe to be right, even if others mock or criticize you for it. Believe in yourself and believe that you can do it under any circumstances, because if you believe you can, then you really will. The belief keeps you searching for answers, which means that pretty soon you will get them.
Second, govern your behavior based on what other people think. What's more important, be willing to take risks and go the extra miles to achieve better results, in which case mistakes can not be avoided. Don't hesitate to admit your mistakes, and learn from them. Next, work hard to settle the problems in order to cover up your mistakes before anyone notices. Building self-confidence is readily achievable, as long as you have the focus and determination to carry things through. And what's even better is that the things you'll do to build self-confidence will also build success -- after all, your confidence will come from real, solid achievement. No one can take this away from you!
As you sow, so shall you reap. With your perseverance and improvement, you are getting closer to success. At this stage, wait for others to congratulate you on your accomplishments and compliments graciously. "Thanks, I really worked hard on that prospectus. I'm pleased you recognize my efforts. " The congratulations and compliments from others will promote you to gain further success.
Self-confidence is extremely important in almost every, aspect of our lives, and it is no wonder that so many people struggle to find it. Self-confidence really can be learned and built on. Besides, whether you're working on your own self-confidence or building the confidence of people around you, it's well-worth the effort!
小題1:Those who are truly confident
A．succeed without effort and hard work
B．encourage people around to become confident
C．a(chǎn)ppear more attractive and thus become successful

Michael Fish may soon be replaced as a weather forecaster by the shark (鯊魚).
Research by a British biology student suggests that sharks could be used to predict storms. Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure. If her studies prove the theory, scientists may be able to monitor the behavior of sharks to predict bad weather.
Miss Smith had previously studied the behavior of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.
Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”
“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal (潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic (模擬) oceanic pressure changes caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.
小題1:The passage is most probably taken from _______.
A．a(chǎn) short-story collection
B．a(chǎn) popular science magazine
C．a(chǎn) research paper
D．a(chǎn) personal diary
小題2:What do we learn from the first four paragraphs of the passage?
A．Sharks may be used to predict bad weather.
B．Sharks’ behavior can be controlled.
C．Michael Fish is not fit for his job.
D．Lauren Smith will become a weather forecaster.
小題3:Lauren Smith conducted her research by _______.
A．removing hair cells from a shark’s balance system
B．measuring the air pressure of weather fronts
C．recording sharks’ body temperature
D．monitoring sharks’ reaction to weather changes
小題4:What is the passage mainly about?
A．A popular way of forecasting weather.
B．A new research effort in predicting storms.
C．Biologists’ interest in the secrets of sharks.
D．Lauren Smith’s devotion to scientific research.

To learn an instrument(樂器) such as the violin or accordion（手風琴）takes years. The job opportunities for musicians are scarce and competition is fierce. Then why are more people than ever before paying a lot of good cash to get their children the best music teaching they can afford?
The secret lies in the influence of music on the whole person. It has been found that learning a musical instrument actually increases a person’s IQ over time. Different instruments and different trypes of music have varying effect, with classical music and the string（弦樂） family coming out on top, potentially increasing you IQ by up to 12 points!
When is a good time to start learning music? Experts have found that even the fetus（胎兒）can benefit from listening to classical music. Surround yourself and your family with good music from the first. The Suzuki Piano Method teaches children from the age of 3 years piano, with two lessons per week. From preschool, children can learn to read music and play from sheet music. Progress in learning your instrument is directly proportional（成比例的）to the amount of practicing.
Is there such a thing as an unmusical child? Shinichi Suzuki proposes that music is the native home language of all human beings and therefore nobody can be “unmusical”. Of course there are exceptional talents, compared to which others may seem to be slower learners.
Is there any benefit for adults in starting an instrument? Apart from the purely relaxing aspect, yes. Learning an instrument can earn even adults additional IQ points, and as an added benefit in improves your health by reducing your stress levels. Your social life may benefit too, if you are prepared to come out of your box and join occasions such as Ceilidhs (musical get-togethers) or arrange house concerts. It has been established that people who play instruments tend to be more emotionally balanced and more patient with themselves, others and life in general.
So go ahead, sign up for that amateur orchestra, dust off your old trombone（長號）or take your first real six-string down from the attic（閣樓）; get out there and play!
小題1:Playing which of the following musical instruments can help increase a person’s IQ most?
A．The pianoB．The violinC．The tromboneD．The accordion

Technology is making life easier for some dairy farmers. They use robotic systems to milk their cows. Cows are trained to follow a series of paths that lead to milking stations. Only one cow at a time can enter a station.
Once inside, the cow is rewarded with food. As the cow eats, a robotic arm cleans and connects the animal to the milking machine. A few minutes later, milking is complete. The gate is opened, the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day. The cows get to decide when they want to be milked. Cows are milked an average of about three times a day. Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system. A computer keeps records on their eating and milking. A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk. Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers. She means young people who are more interested in technology and less interested in working all the time on the farm. Still, she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm. Last year it became the fourth farm in southeast Minnesota to get a robotic milking system. A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars. The second cost 150 000.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot. He says the increase in milk production reaches a high of more than six kilograms per cow per day.
小題1:From the first paragraph, we can infer________.
A．the robotic system is designed to reduce labor
B．cows can be raised by robots in the future
C．robots direct cows into milking stations
D．cows are kept clean by robots on some farms
小題2:Besides milking cows, the robotic system also can ________.
A．a(chǎn)djust the temperature of milking stations
B．judge the quality of fresh milk
C．improve the appetite of cows
D．keep fresh milk for two weeks
小題3:Why is the robotic system not popular now?
A．Because young people have no interest in it.
B．Because it is difficult to learn how to use it.
C．Because people can’t afford to buy it.
D．Because it usually causes the waste of milk.
小題4:According to Doug, what is the wage of an employee?
A．150, 000-170, 000.B．750, 000.C．150, 000 -30, 000.D．30, 000- 32, 000
小題5:The best title for the passage may be_______.
A．Letting robot milk your cowB．Milking cows by hand
C．Improving the quality of milkD．Drinking fresh milk every day

What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?
We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop.  The second is the application of the special methods of thought and action that scientists use in their work. 
What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.
He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光譜).
He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.
Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.
Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.
These seem to be some of the ways in which a successful scientist or technologist thinks and acts. 
小題1:Many people believe that science helps society to progress through_________
A．knowledge only.B．more than one aspect.
C．technology only.D．the use of machines.
小題2:Which of the following statements about a curious scientist is TRUE?
A．He doesn’t find confidence and pleasure in work.
B．He is interested in problems that are explained.
C．He makes efforts to investigate potential connections.
D．He looks for new ways of acting.
小題3:According to the passage, a successful scientist would NOT_______________.
A．easily believe in unchecked statements.
B．easily criticize others' research work.
C．a(chǎn)lways use his imagination in work.
D．a(chǎn)lways use evidence from observation.
小題4:Which word can be used to describe the data that a good scientist uses?
A．completeB．objectiveC．complicatedD．a(chǎn)ccurate

The quest for success always begins with a target. As Berra once said , ＂you get to be very careful if you don＇t know where you＇re going, because you might not get there.＂
Too many people wander through life like sleepwalkers. Each day they follow familiar routines, never asking, ＂What am I doing with my life?＂and they don＇t know what they＇re doing because they lack goals.
Goal-setting is a focus of the will to move in a certain direction. Begin with a clear conception of what you want. Write down your goals and date them---putting them into words clarifies them. Rather than concentrating on objects to acquire and possess, focus on fulfilling your desires to do, to produce, to contribute to goal-setting that yields the true sense of satisfaction we all need.
It’s important to visualize(想象)yourself accomplishing your goal. While losers visualize the penalties(不利) of failure, winners visualize the rewards of success. I’ve seen it among athletes, statistics contrasting air and highway safety, but it made no difference. I had read too many articles describing crash scenes and imagined these scenes vividly. I had programmed myself, without realizing it ,to stay off planes.
Then one summer I had the opportunity to fly on a private plane with friends to a resort; I didn’t want to miss out on a great vacation. So I spent two weeks imagining a smooth flight on a beautiful sunny day and an easy landing.
When the day arrived, I was eager to go . To everyone＇s surprise, I got on the plane and I loved every minute of it , and I still use the techniques I employed that day.
小題1:According to the passage, if you want to be successful ,the first thing for you to do is to         .
A．find the right methodsB．be careful about everything
C．know your abilityD．have a clear goal
小題2:The problem with the author before he overcame his fear of air travel is that        .
A．he didn’t know air travel is safer than highway travel
B．he couldn’t imagine himself accomplishing his goal
C．he read too much about plane crashes and tried to avoid flying
D．he wanted to take a private plane instead of a public one
小題3:What would be the best title for this passage?
A．Defining Your GoalB．Visualizing Reward of Success
C．Overcoming the Fear of Air TravelD．Sleepwalking Through life
