In the near future, people in some parts of the world will watch a new kind of television. It is called the high definition television or the HD-TV. The main difference between an HD-TV and a normal television is the picture. It is more clear and detailed. This is because the HD-TV has many more points and lines that make a television image. Every color television picture contains thousands of red, green and blue points. They all come together as an image in the eye of the person watching. The points are organized in lines that go across the television screen. There are more than five hundred lines in a normal television. The HD-TV has two times as many. To get this clear picture, you must have a big screen. Experts say people using a small screen will see little difference.
The HD-TV also has clear sound. It is like the sound on a CD. All these improvements make an HD-TV very costly. One kind in Japan now sells for more than twenty thousand dollars .A major problem with the HD-TV is its broadcast signal（傳播信號.The signal is bigger than normal because it carries more electronic information.

Would you want a doctor who got high marks in medical school just for trying hard? Apparently many college students would have no problem with that. They believe students are owed a good grade simply because they put a lot of effort into a class.
The researchers asked more than 800 undergraduates if they agreed or disagreed with some statements. For example: "If I have completed most of the reading for a class, I deserve a B in that course." And: "A professor should not be annoyed with me if I receive an important call during class."
Just 16 percent thought it was OK to take that phone call. But 66 percent agreed that a professor should consider effort and not just the quality of a student's work when deciding grades. And 40 percent thought they should get a B, the second highest mark, just because they did most of the reading for class.
Some experts are not surprised that students often see no difference between effort and results. Social critics like to say that in children's activities these days everyone gets an award just for trying, so no one will feel rejected.
Yet competition to get into the best colleges is fiercer than ever. Students may worry that low grades will keep them out of graduate school or a good job.
And there may be another explanation: pressure from parents to get a good return on the family's investment. These days, college can cost more than a house.
A former teaching assistant recently wrote to the New York Times about his experience with grade expectations. He would try to explain it this way when students asked for a top grade just for studying hard in chemistry class:
What if a baseball player came to spring training and worked harder than all the others, but still could not play well? Would the team accept him anyway, just because he tried so hard?
The students would say no. But most of them would still ask for an A.
小題1:What does the passage mainly discuss?

A．How students can get a good grade in the course.

B．Whether students are allowed to answer calls in class.

C．Whether students deserve high marks just for trying hard.

D．Why students put a lot of efforts in their studies.

小題2:According to the research, most of the students _______.
A. thought it was all right to answer the call during class.
B. objected to deciding grades only by the quality of a student’s work.
C. thought they did most of the work for class and should get a B.
D. agreed that they should be given top grades because of their hard work.
小題3: Which of the following opinions do social critics agree to about children’s activities?

A．Those who are active in the activities can get an award.

B．Only by playing an important role in the activities can you get an award.

C．An award is prepared for anyone who performs best in the activities.

D．Whoever takes part in the activities can get an award.

小題4:From the sixth paragraph we can learn that _____.

A．it costs much more to build a college than to buy a house.

B．the costs of studying at college are much more than staying at home.

C．the costs of sending a child to college are much more than buying a house.

D．it is difficult for parents to send a child to college.

小題5:What does the former assistant want to tell students with the example of the baseball player?

A．Effort can lead to good results.	B．Effort is very necessary.
C．Effort and results are quite different.	D．No good results, effort is unnecessary.

High school graduation is worth celebrating. It marks a big change in the lives of young adults. However, it ought to mean even more. It ought to mean that the graduate is ready for college or career.
In a report issued last year, we found that almost half of recent Illinois high school graduates required remedial courses(補(bǔ)習(xí)課) upon enrolling(注冊) a community college. These courses require time and money to complete, yet offer no credits toward a degree. Too often, students never get through those remedial courses and end up dropping out of college.
Why is the remediation rate so high? A large part of the reason is that we have not set high enough standards for what our students need to learn from kindergarten to high school. They simply aren’t equipped with the knowledge and skills they need to succeed.
The same is true for careers. In Illinois, good jobs continue to go vacant(空缺) even while we are trying hard to go through tough economic times. This is due largely to the mismatch between the skills and knowledge we provide our students with and what employers in a modern economy need workers to know.
The good news is that in Illinois we have a plan to help get our students ready for life in the real world. We have already taken an important first step by becoming one of the 45 states to adopt the Common Core State Standards and have begun introducing them to classrooms this year. The new standards provide fewer, clearer and higher benchmarks(標(biāo)準(zhǔn)) for academic progress. They focus on deeper knowledge required at each grade level, give teachers the opportunity to explore topics fully and ensure students can apply what they’ve learned.
Research shows that when expectations are raised, students rise to meet them. Adapting to higher standards and raising expectations may prove challenging, but they are the steps we must take so that our students are successful in high school and prepared for college and careers. Readiness is worth a celebration.
小題1:According to the passage, in most cases, students taking part in remedial courses ___.

A．come from wealthy families

B．leave college before finishing their courses

C．a(chǎn)re offered credits toward a degree

D．a(chǎn)re likely to develop their academic interest

小題2:The author uses the third and fourth paragraphs to __.

A．provide solutions to the rising remediation rate

B．show the present situation of unemployment in Illinois

C．suggest knowledge learned in school be put into practice

D．explain why students aren’t prepared for college and a career

小題3:Which of the following statements about the Common Core State Standards is TRUE?

A．They were first adopted in Illinois.

B．More benchmarks are required.

C．They benefit teachers as well as students.

D．They ensure students’ success in college.

小題4:Based on the last paragraph, what is the author’s attitude to raising expectations of students?

A．Supportive	B．Critical
C．Doubtful	D．Worried

A messy desk can actually lead people towards clearer thinking, say researchers from Germany．
The researchers found in a series of linked studies - using a messy desk and a messy shop front - that people actually thought more clearly when all around was chaos, as they sought to simplify the tasks at hand.
Visual and mental clutter（阻塞） forces human beings to focus and think more clearly.
Famous thinkers and writers such as Albert Einstein and Roald Dahl have been notorious（聲名狼藉的） for their untidy desks.
“Messy desks may not be as detrimental（有害的） as they appear to be, as the problem-solving approaches they seem to cause can improve work efficiency or increase employees' creativity in problem solving,” say the authors.
“Business and government managers often promote 'clean desk' policies to avoid disorganized offices and messy desks, for the purpose of boosting work efficiency and productivity,” writes lead researcher Jia Liu of the University of Groningen in a paper published in the Journal of Consumer Research.
“This practice is based on the conventional wisdom that a disorganized and messy environment can clutter one's mind and complicate one's judgments.”
“However, not all evidence supports this conventional link between a messy environment and a messy mind.”
The scientists tested people's response in various 'messy' environments - including a messy shop front, a disorganized desk, and even a work environment where a language task 'reminded' people of messiness.
The authors found in the series of six studies people tended towards simplicity in their thinking.
“They categorized （分類） products in a simpler manner, were willing to pay more for a T-shirt that shows a simple-looking picture, and sought less variety in their choices.” said the researchers.
小題1: The purpose of the first two paragraphs is to show that _____．

A．A messy desk cannot contribute to clearer thinking

B．People thought more clearly about a messy desk and a shop front

C．People will feel confused when all around are chaos

D．People manage to simplify the tasks in messy environments

小題2: Why does the author take Albert Einstein as an example?

A．to support the idea that clearer thinking comes from messy environment．

B．to tell the fact that Einstein was known for his untidy desks．

C．to stop us from learning from Albert Einstein．

D．to call on us to develop a good habit．

小題3:How do people look at messy environment according to the conventional wisdom?

A．Messy environment will create clearer thinking．

B．Messy environment will simplify one' s judgment．

C．Messy environment can promote work efficiency．

D．Messy environment can block one' s mind．

小題4: What does the last paragraph imply?

A．People believe messy environment creates clearer thinking．

B．People sought more simplicity in the choices．

C．People were not willing to choose those complicated products．

D．Not all the people accept messy environment and complicated things

Back those photos up
The images were striking. Homes on the East Coast were washed away by Superstorm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions.
If that doesn’t move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before—including one-click access to a lifetime of family photos.
Here is a brochure on how to back up (存) your photos and save them online, where they can live forever and be accessible in good times and bad.
Scanning
The first step for those old photos is to scan them and save them to a digital format. Most printers come with scanners these days, so that’s an easy but extremely time-consuming step.
Storing the photos
With your scans in place, import the photos into your computer, and back them up.
You could make multiple copies of the disks and spread them to loved ones. Or you could choose external(外接的) hard drives or USB thumb drive, and add your photo and video collection from your computer.
Online backup
If you need lots of space, look at a pure online backup service, Caronite.
Caronite backs up 300 million files daily. Once you sign up, it starts to pick up everything you have on your hard drive. But photo collection on your computer’s main hard drive charges for $59 a year.
Cloud Storage
For folks who don’t need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft’s SkyDrive let you store files online by yourself, share and instantly access them. All offer free options—2GB of free storage for Dropbox, 5GB for Google and 7GB for SkyDrive. But if you want more, you need to pay.
Bottom Line
The hard drive or flash drive is the cheapest and easiest. But drives can fail. Online services are more expensive, but more secure. With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are.
小題1:Why does the author mention Superstorm Sandy?

A．To tell the background of the scanning photos.

B．To attract the readers’ interest in the backups.

C．describe a severe natural disaster.

D．To win the readers’ sympathy.

小題2:What can we know from the passage?

A．Scanning photos takes little time but costs a lot.

B．Caronite charges for backing up photos from hard drive.

C．Google Drive offers unlimited free photo storage on line.

D．The hard drive or flash drive is the cheapest and safest.

小題3:Which of the following allows storing files automatically?

A．Caronite.

B．Dropbox.

C．SkyDrive.

D．Flash drive.

小題4:What’s the passage mainly about ?

A．tell real stories about storage services

B．introduce some of the storage services

C．describe the functions of storage services

D．a(chǎn)rgue about the advantage of storage services

The quality of water supply in southern Beijing has been improving in recent years, an official said.
In addition to improvements in the network of pipes, the government has been upgrading three recycled water plants in the south of the capital, said Zhao Lei, spokesman for the Beijing Municipal Commission of Development and Reform.
"The transformation of the three plants has increased the recycled water processing capacity by 160,000 cubic meters per day," he said.
In addition, the city is also speeding up the construction of sewage treatment plants to further recycle the sewage, Zhao said.
Zhang Xiang, a researcher from Nature University, an environmental protection NGO in Beijing, said recycled water use should be promoted, especially in water-scarce cities such as Beijing.
Setting up more recycled water plants in the capital will not only promote efficient water use, but also reduce costs because recycling water is much cheaper than transferring it over long distances, he said.
According to the Beijing Water Authority, the capital will set up 46 more recycled water plants citywide in the next three years while upgrading 20 sewage treatment plants.
The treatment rate of domestic sewage in downtown Beijing will reach 98 percent by the end of 2015, it said.
The capital's recycled water is mainly used for industry, landscaping and cleaning, Zhang said.
Many new communities in southern Beijing are equipped with a network to recycle water.
In the past, people were not enthusiastic about using recycled water. However, as the government has boosted the quality of recycled water and set up more recycled water plants, more residents are gradually accepting it.
Residents in southern Beijing will also enjoy more clean energy, as the government will replace traditional coal-burning stoves with electric radiators as part of a three-year plan to develop southern Beijing from 2013 to 2015.
Since 2010, Beijing has taken measures to develop its southern areas. Earlier efforts have seen the region, which used to rely heavily on low-end industries such as cement factories and small coal mines, being turned into a bustling commercial center and home to many educational institutions.
小題1:This passage may appear in ________ section.

A．business

B．life

C．politics

D．forum

Chicken feathers are useful, and not just to a chicken. Some go into pillows, coats and other products. But countless chicken feathers go to waste.
In the United States, billions of chickens are produced yearly. Most of their feathers are thrown away.
But instead of being buried in land, some feathers could find a future in plastics（塑料）.
One of the products they have developed is a flowerpot（花盆）. It may look like other flowerpots. But the container breaks down in the earth within one to five years. And as it breaks down, it naturally becomes nutrient（營養(yǎng)物） in the soil.
The environmentally friendly flowerpot is the work of two researchers. Walter Schmidt is with the Agricultural Research Service, part of the United States Agriculture Department. Masud Huda is with the Horticultural Research Institute, a private（私人） organization（組織）.
Walter Schmidt has been working to find uses for chicken feathers since the 1990s. Progress in 2002 showed that plastic made from feathers could be formed like other plastics.
He says feathers are much stronger and last（持續(xù)） longer than another plant material. "Feathers are stronger. By design, feathers are also more durable（耐用的）. And the other part about it is if feathers were twice as heavy, or half as strong, then birds couldn't fly."
He points out that traditional flowerpots made from other plastics can last much longer. But he wonders if there is really a need. He says most flowerpots are never re-used.
"Why would you want a plastic that you use for a year to last for two hundred years? It makes no sense. You want to match the product with the use." said Walter Schmidt.
Walter Schmidt and Masud Huda are now adding another chicken product to their flowerpots -- chicken waste. The waste will add more nutrients to the soil as the pot breaks down. The scientists say they hope their flowerpot will be on the market in a year or two.
小題1:What do people mainly deal with feathers?

A．Feathers are used to make pillows, coats and other products.

B．Most feathers are paid no attention to.

C．Most feathers are used as nutrient

D．Most feathers are used to make flowerpots

小題2:What’s the advantage of the flowerpots?

A．They won’t last long.	B．They can’t break
C．They are environmentally friendly	D．They can be reused

小題3:What does Walter Schmidt think of traditional flowerpots?

A．Too heavy	B．Too old
C．Never re-used	D．lasting longer but unnecessary

小題4:What do you think is the main idea of the passage?

A．Chicken and its feathers	B．How to deal with feathers
C．feathers made into flowerpot	D．New flowerpots

London—coffee protects mice from radiation and could get the same way in humans, according to Indian scientists.
Scientist at India’s Bhabha Atomic Research Center discovered that mice injected with caffeine (咖啡因)remained alive after high doses(劑量)of normally lethal radiation.
Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans .
“It does suggest that coffee might have some beneficial effects in protecting against radiation,” he told New Scientist magazine late last month.
George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation(伽瑪射線),enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams(毫克)of caffeine per kilogram of body weight were still alive.
On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died.
小題1:George and his team drew the conclusion from .

A．the magazine

B．their invention

C．the experiment

D．their experience

小題2:From the news, we know can be protected from radiation.

A．both mice and humans	B．only mice
C．only humans	D．neither humans nor mice

小題3:From paragraph 5, we know 30 percent of the mice died 25 days later. The reason was probably that .

A．these mice had been given only 80 milligrams of caffeine

B．these mice hadn’t been injected with caffeine

C．these mice were very big and strong

D．these mice hadn’t been given enough caffeine

小題4:Which is the best title of the article?

A．Human and Mice	B．New Radiation Defense—Coffee
C．Deadly Radiation—Gamma Radiation	D．Mice Died of Caffeine

小題5:In paragraph 2,the underlined word “ lethal ”means .

A．causing death

B．lively

C．exciting

D．rich
