Modern festival-goers who worry about ending up with a dead mobile phone battery(電池) after days stuck in a muddy field with no electric plug power points may now have a solution——power boots(靴子).
Mobile phone company European Telco Orange has introduced a phone charging(充電) prototype—— a set of thermoelectric gumboots or Wellington boots with a “power generation sole” that changes heat from the wearer’s feet into electrical power to charge battery-powered hand-helds.
The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. “In the sole of the Wellington boot there’s a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge,” Pain said. “That electrical charge we then pass through to a battery which you’ll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone.” These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers. When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made.
But the prototype boot does have one drawback. You have to walk for 12 hours in the boots to make one hour’s worth of charge.
1.The passage is probably taken from _____________ of a website.
A. the business book B. the sports book
C. the science book D. the health book
2.What’s the main idea of the third paragraph?
A. How the boot works to make electricity.
B. How long the boot can be used.
C. Who invented the power boot.
D. The weakness of the boot.
3.Which of the following can replace the underlined word “drawback” in the last paragraph?
A. Benefit. B. Disadvantage.
C. Patience. D. Function.
4.The invention seems to be good news to those___________.
A. who like traveling in the wild
B. who work at home
C. who study at school
D. who work at an office

As we all know, millions of people worldwide cook their food over smoky fire every day. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun.
Solar cooker, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in seventeen sixty-seven. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.
There are three kinds of solar ovens. The first is a box cooker, It is designed with a special wall that shines or reflects sunlight into the box .Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food.
The second kind of solar oven is a panel cooker. It includes several flat walls or panels that directly reflect the sun’s light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya ,for example ,panel cookers are being manufactured for just two dollars.
The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven .Food cooks quickly in parabolic ovens .However, these cookers are hard to make. They must be re-aimed often to follow the sun .Parabolic cookers can also cause burns and eye injuries if they are not used correctly.
You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.
1.If you have much food to cook , you’d better choose________ .
A. a box cooker B. a panel cooker
C. a parabolic cooker D. a paper cooker
2.According to the passage we can conclude that ______.
A. panel cooker is easy to make
B. box cooker is easy to make
C. box cooker is the most effective oven
D. panel cooker is the cheapest oven of the three
3.What is the main purpose of the author in writing the passage?
A. To advertise the solar ovens.
B. To help readers to save cost on fuel.
C. To tell the readers how to make solar ovens.
D. To give the readers brief introduction of solar ovens.

Picture the scene: You come home after work feeling too exhausted to cook –only to find a delicious meal worthy of a Michelin-starred restaurant waiting for you. It sounds like a fantasy, but it could be about to come true thanks to a robot chef developed by British scientists.
Those scientists have come up with a set of robotic arms so smart that they are capable of cooking meals all by themselves. The device will be sold from as early as 2017 as part of a purpose-built high-tech kitchen.
Scientists at Moley Robotics spent almost 18 years developing the hands. According to its creators, the arms can chop, stir, whisk and baste well enough to recreate almost anything you would care to eat, whether it is a simple home-cooked supper, or a complicated creation designed by a world-class chef. The hands move a little slowly, hovering strangely above the work surface whenever they are not busy, but they imitate human movements closely enough that they can do things such as wiping a spoon on the edge of a pan to prevent drips.
Mr Oleynik, who is leading the project, said, “All the things which are possible with the hand are possible here. There is no limitation. A lot of people want to go to Michelin-starred restaurants, but they are quite expensive and may be quite far from the home. This is an opportunity for people to enjoy very good food, and for a reasonable price. ”
The only cuisine that is off the robot’s menu at the moment is sushi, which requires extremely steady pressure and nimble fingers to make, but the team plan to conquer that as well by the time it goes on sale.
1.People go to Michelin-starred restaurants in order to______.
A. appreciate car tires. B. enjoy delicious meals
C. see the new robot chefs D. escape from work
2. What does the underlined word “they” in Paragraph 2 refer to?
A. British scientists B. The robot chef’s arms
C. Cooks at restaurants D. Household wives
3.Which kind of food CAN’T the robot chef cook at present?
A. Bread B. Beef C. Sushi D. Sandwich
4.What can we infer from the passage?
A. Hands of a robot chef can perform exactly like a cook.
B. Robot chefs are available at shopping malls.
C. Michelin-starred restaurants are suitable for many people.
D. It is uncertain when the robot can cook all kinds of food.

Why are so many people afraid to fail? Quite simply because we forget that failure is part of the human life and that every person has the right to fail. Every person is able to fight failure and finally succeed.
Most parents work hard at preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards(標準). When a child finishes making a table, the mother describes it as “perfect” even though it doesn’t stand still. Another way is to blame others. If John fails in science, his teacher is unfair or stupid.
There’s a problem with the two ways. It makes a child unprepared for life in the real world. Young children need to learn that no one can be best at everything, no one can win all the time, and that it’s possible to enjoy a game even when you don’t win. A child often feels terrible, of course, when he is not invited to a birthday party, or is not chosen into a football team. But parents should not say “It doesn’t matter.” quickly. The young should be allowed to experience failure and be helped to come out of it.
Failure never gives people pleasure. It hurts both adults and children. But it can be really good to your life when you learn to use it. You must learn to ask “Why did I fail?” Don’t blame anyone else. Ask yourself what you did wrong and how you can improve. If someone else can help, don’t be shy about asking them. Success just repeats what has been done. It is not as good a teacher as failure. You can learn how to give a good party from an unsuccessful one.
1. How do most parents prevent their children from failure?
A. They give them some presents.
B. They don’t tell them that they have failed.
C. They don’t blame others.
D. They help them to come out of failure.
2. Which of the following does a person need to learn when he fails?
A. It’s impossible to enjoy a game if he misses it.
B. He is the worst of all.
C. It’s natural not to win a game and no one can win all the time.
D. His teammates are not good enough.
3.Which would be the best title for the passage?[來.Com]
A. Learning from Failure
B. Ways of Preventing Failure
C. Reasons of Failure
D. Getting Pleasure from Failure

Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate(桂冠). As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi.
Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career.
Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations.
Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them.
Aided by computers, Hoffmann was able to generate a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value.
1.What can be inferred from the above passage about Hoffman?
A. He left his homeland when he got the Nobel Prize.
B. He went to the United States to gain his Nobel Prize.
C. He might find the Unites States a better place to learn chemistry.
D. His family may have settled in the United States.
2.How did Hoffman make his research popular?
A. He applied some computer skills to help explain his ideas.
B. He established a special computer system to help.
C. He drew some forms explaining his ideas.
D. He did series of experiments to prove his ideas.
3.The underlined word “generate” in this passage might most probably mean “______”.
A. bring in B. break down
B. move away D. keep secret
4.Why was Ronald Hoffman awarded the 1981 Nobel Prize for chemistry?
A. He established rules to predict chemical reactions .
B. He succeeded applying computer science to chemistry research.
C. He shared what he had achieved with another scientist named Fukui Kenichi.
D. He succeeded in both chemistry and computer researches.
