Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a turn of a switch.
“It took us a long time to figure out what a window really is,” says Claes Granqvist, a professor of solid—state physics at Uppsala University in Sweden.“It’s contact with the outside world. You have to have visual contact with the surrounding world to feel well.” So, windows and natural light are important for improving the way people feel when they’re stuck indoors.
Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it’s hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world.
Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use some technologies involving changes of color.
Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers(層) of tungsten oxide(氧化鎢) works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage(電壓) is decreased, the window darkens until it’s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark.
One important feature that makes a smart window so smart is that it has a sort of “memory”. All it takes is a small shock of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need.“In the future,” Granqvist says,“our buildings may look different.”
67.Which statement does not indicate the importance of windows as described in the first two paragraphs?
A.Windows can change from clear to dark to save energy.
B.Windows help to save energy by letting light in.
C.Windows help to save energy by providing heat.
D.Windows enable people to have contact with the outside world.
68.According to the passage, smart windows are windows_______.
A.that are coated                        B.that use electricity
C.the color of which can be changed        D.that have many layers
69.To make electrochromic windows change color, what is applied to the window glass?
A.Electricity.     B.Tungsten oxide.    C.A battery.         D.A voltage.
70.What will be the benefit if the research on smart windows turns out to be successful?
A.The buildings will look different.
B.Windows can be as large as you want.
C.We may not need air conditioners any more.
D.They are less expensive than traditional windows.

Elephants are famous for their supposedly excellent memory. Now it seems that they are good at simple math too.
Researchers at the University of Tokyo have found an Asian elephant named Ashya can add small quantities together and correctly identify(識(shí)別）which is larger.
For example ,when researcher Naoko dropped three apples into one bucket and one apple into a second, then four more apples into the first and five into the second, Ashya correctly identified that the first bucket contained more apples and began munching(嚼）on her tasty prize.
Ashya chose the correct bucket 74% of the time "I even get confused when "I'm dropping the apple," Naoko told New Scientist magazine.
Elephants' counting abilities are far from unique. Chimps, pigeons(鴿子)and dolphins have shown the same abilities in lab tests, but what is more impressive for Elephants is that their ability to tell between two figures does not get worse when those numbers are more similar.
The elephants that Naoko tested were as good at telling the difference between five and six as they were at telling between five and one.
Naoko presented her findings last week at the International Society annual meeting in New York.
It is not obvious why elephants should need this mathematical ability in the wild." It is really tough to figure out why elephants would need to count," said Mya, a professor at Cornell University who studies elephants.
One possibility is that they use it to keep track of other members of their herd(獸群）so that no one is left behind. Asian elephants live in groups of six to eight." You really don't want to lose your group members," said Mya.
Another possibility is that the ability for simple math might be a by-product(副產(chǎn)品）of natural selection for a larger brain.
68.The experiments researchers have done recently show that elephants can____.
A. memorize things correctly      B. munch on apples
C. do some simple math          D. change small quantities into larger ones
69.What does the underlined word" tough" in Paragraph 8 mean?
A. Difficult        B. Impossible     C. Easy      D. Useful
70.The reason why elephants need to count is possibly that_____.
A. they want to exercise their brains
B .they often count the members of their herd
C. they hope to stay in groups
D. they have taken regular training

Great Minds Reminded of Mom
After a long, exhausting day, a friend of mine, Allen, headed home. On the road, he passed an elderly woman who was standing by a car with a flat tire. If that were his mother, he thought, he would want someone to help her. With a tired sigh, he turned around and drove back.
Just as he reached the stranded woman, a truck pulled up and a burly farmer got out. "Kindof reminds you of your mom, too?" the man asked as the two of them pitched in together to change the tire for the woman.

Snow can be very beautiful. When snow covers everything around you , the world looks like a “Winter Wonderland”. That is the name of a very popular song about winter. Richard Smith and Felix Bernard wrote the song in 1934.
But winter is not always such a beautiful and happy time. It is cold outside.The wind blows and makes it even colder. The days are shorter and darker. The sun rarely shines. The leaves on the trees are brown or have fallen to the ground. The flowers are mostly gone. It is not surprising that some people are sad in winter. And some people dream about being somewhere else where it is warm and pretty——like the state of California. The Mamas and the Papas recorded their famous song, “California Dreaming” in 1965.
During the 1960s, many other famous rock groups sang songs about winter. Here is a song by Simon and Garfunkel called “A Hazy Shade of Winter”. They sing about life and hope.
In 1968, the group Blood, Sweat and Tears recorded this gentle, sad song about winter. They sing about a lost love and forgotten memories in “Sometimes in Winter”.
Gordon Lightfoot wrote and recorded another sad and lovely song about winter in 1975.Sarah McLachlan recorded “Song for a Winter’s Night” for an album in 2006.She sings about reading a love letter and wishing the writer were with her.

 Thousands of people began pouring into Pennsylvania from other states. They wanted to buy lottery tickets. The tickets cost only $0．9 each ．But that small spending could bring them a reward of $90 million. That was the second largest lottery jackpot（積累獎(jiǎng)金）in history.
More than 87 million tickets were bought for the Pennsylvania lottery drawing. Those who bought tickets had to choose seven numbers from 1 to 80. The chance of winning was one in 9．6 million. But that little chance certainly didn’t affect ticket sales. In the last few days before the drawing , tickets were selling at the unbelievable rate of 500 per second.
Experts say many people buy lottery tickets because they just want to have a piece of the action. Others say the lottery is a stock market for poor people. It allows them to dream about wealth they’ll probably never have.
But many people believe lotteries are no better than legalized gambling. Some critics note that most people who play are poor and may not be able to afford the tickets. There are also many addicts who take the game seriously. They may pour their life savings into lottery tickets. Some clubs have been formed to help them kick the habit.
Politicians like lotteries because they provide money that would otherwise have to some from new taxes. The profits from lotteries are usually used to pay for education or programs for senior citizens. But critics say this arrangement just allows states to legalize vice（惡習(xí)）, under the name of social progress. No matter whether you regard state lotteries right or not , you cannot refuse to accept their extreme popularity with many Americans.
57. The main idea of the passage is that       ．
A．lotteries are of great benefit to everyone who buys them
B．playing a lottery is just like investing in the stock market
C．a(chǎn) lot of people buy lottery tickets , but lotteries cause disagreement
D．lotteries are just legalized vice
58. Which of the following is TRUE according to the passage ?
A．Politicians like lotteries because they don’t have to pay extra tax ．
B．The popularity of lotteries in America actually is social progress ．
C．Some critics don’t like lotteries because many poor people waste their money on them ．
D．People love the lottery because it is a stock market ．

Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobiliser (鎖止器), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again.
The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro- processor and memory, and a GPS (全球定位系統(tǒng)) satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted.
In the UK, a set of technical fixes is already making life harder for car thieves. 'The pattern of vehicle crime has changed,’ says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old.
Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code beamed out by the ignition (點(diǎn)火) key. In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997.
But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.
If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal.
Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit.
66. What's the function of the remote immobilizer fitted to a car?
A .To allow the car to lock automatically when stolen.
B. To prevent the car thief from restarting it once it stops.
C. To help the police make a surprise attack on the car thief.
D. To prevent car theft by sending a radio signal to the car owner.
67. By saying 'The pattern of vehicle crime has changed' (Lines 1-2. Para. 3). Martyn Randall suggests that ____.
A. self-prepared tools are no longer enough for car theft
B. the thief has to make use of computer technology
C. it takes a longer time for the car thief to do the stealing
D. the thief has lost interest in stealing cars over 10 years old
68. What is essential in making a modern car tougher to steal?
A. A GPS satellite positioning receiver.　      B. A unique ID card.   
C. A special cellphone signal.                D. A coded ignition key.
69. Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?
A. To give the driver time to contact the operations centre.
B. To allow for possible errors in the GPS system.
C. To keep police informed of the car's movements.
D. To leave time for the operations centre to give an alarm.
70. What will the operations centre do first after receiving an alarm?
A. Start the tracking system.         B. Locate the missing car.
C. Contact the car owner.　         D. Block the car engine

One of the worst feelings in the world is trying your hardest at something but still falling short. In the case of schoolwork, studying for hours and bringing home disappointing grades may make you feel hopeless or helpless, but this is far from the truth. If you are dealing with disappointing grades, promise to change your study habits and you'll be amazed by the results.
Act Fast
The most important rule about dealing with disappointing grades is to act fast. Don't sit around and let them get worse, and definitely don't ignore them. Instead, admit that you need help and go in search of it soon. The faster you face up to the problem, the faster you can find a solution and see some results.
Tweak your routine
If you are studying hard and still dealing with disappointing grades, it's probably time to tweak your routine a little. Remember, if you keep doing the same thing all the time you'll undoubtedly keep getting the same results. Mix things up by asking for help, whether from a friend or fellow student, your teacher or a private tutor. Ask for help with the subject matter and tips for studying on your own.
Study Successfully
Of course it doesn't matter where you study or who you study with if you are studying the wrong things. Make sure that you are studying successfully by:
*Reviewing your textbooks.
*Looking over your notes from class.
*Taking new notes while you study.
*Investing in study guides.
*Answering all of the review questions you can find.
*Talking through events or concepts that are integral (整體) to your lessons.
Learn From Your Mistakes
If, after all of your changes and redoubling your study efforts, you are still disappointed with your grades, then it is time to figure out exactly where you are going wrong. Look over exam papers and assignments to see if you are having trouble with a particular kind of question (multiple choice, true or false, etc.) or concept. Examine your essays to see if you are explaining your ideas clearly and completely, or if it is the mechanics of your writing (spelling, grammar, etc.) that is letting you down. Request an appointment with your teacher and use this time to discuss your work and get his/her feedback as well.
Dealing with disappointing grades is something that every student will face at one time or another. It won't be fun, but take a realistic look at your attention in class, your study habits and your performance on past assignments and exam. Figure out where you are having trouble and dedicate yourself to fixing these problems.
51. The purpose of this passage is _______.
A. to introduce practical ways to solve worrying school problems
B. to persuade students to change their attitude toward schoolwork
C. to offer advice on how to improve academic grades at school
D. to emphasize the importance of dealing with disappointing grades
52. The underlined phrase to tweak your routine means _______.
A. to stick to the same study plan and seek help when possible
B. to mix things up before you work out a practical solution alone
C. to examine your everyday life to make room for self improvement
D. to make necessary alterations in your study habits and plans
53. According to the passage, it is desirable to _______.
A. adopt a great variety of successful study methods and work on your own
B. have a study partner who act fast to face up a problem and study successfully
C. find out your weak points by reviewing schoolwork and seek necessary help
D. make an appointment with your teachers and develop useful examination skills
54. The author of this passage is probably a(an) _______.
A. psychologist         B. examiner       C. parent         D. instructor
55. The author thinks that dealing with disappointing grades calls for _______.
A. a strong will power                     B. a down-to-earth attitude
C. creativity and dedication                 D. undivided attention
