You may not be aware, but digital currency (货币) is a big part of the Internet world. QQ Coins can buy you accessories (配饰) for your QQ images. More importantly, a new digital currency, Bitcoin, is bringing the world’s commerce online.
If you’re traveling, you can spend Bitcoins at restaurants and hotels listed at BitcoinTravel.com. In China, Bitcoins can be used to buy goods at about 134 online shops on Taobao. And at a café named 2nd Place in Beijing, you can even buy fresh coffee with Bitcoins.
So what makes Bitcoin so attractive to investors?
First of all, the Bitcoin system is not controlled by anyone. One central authority cannot make policies to change the value of Bitcoins. The fixed amount of Bitcoins also means they cannot lose value through inflation(通货膨胀), as all forms of paper money have done over time.
In addition, accounts in the Bitcoin system are anonymous and transparent. Users can set up an account easily and track every Bitcoin. All of these features seem to make Bitcoins immune(有免疫力的) from loss, but that is not entirely true.
“The value of Bitcoins can vary wildly as no central government makes the price of them steady. If the value drops suddenly, investors cannot get any compensation(赔偿),” Zhao Qingming, a senior researcher at China Construction Bank, told China Economic Weekly. And Bitcoins, unlike company shares, are not backed by any tangible assets(有形资产), which also adds to their risk.
While China will not recognize the digital currency anytime soon, Xinhua said, lawmakers and officials at a hearing on Nov. 18 in the US made positive comments about Bitcoin.
Ben Bernanke, outgoing chairman of the Federal Reserve, told the Washington Post that “these types of creations, such as Bitcoin… may hold long-term promise, particularly if its system promote a faster, more secure and more efficient payment system.”
1.Bitcoin is ______.
A. actually exactly like QQ Coins B. only used online
C. a new currency used both online and in real life D. a country’s new digital currency.
2.We can use Bitcoin to buy the following things except ______.
A. online goods B. goods at 134 online shops on Taobao
C. books in physical shops D. coffee at a café named 2nd Place
3.What is the disadvantage of Bitcoin?
A. the value of it can rise and fall wildly.
B. It cannot lose value through inflation.
C. Every bitcoin in your account can be followed.
D. It can even be used at some specific restaurants and hotels.

We may be living in the digital age, but reading books is still a big part of growing up. When they’re in primary school, children read books that really challenge them. But once they reach secondary school, the level of difficulty doesn’t change much. Secondary school students tend to read books which are also read by upper primary students. They are not challenging themselves enough.
To discover these trends, I analyzed data collected by Accelerated Reader (AR) software, which asks pupils to check their understanding of the books they’ve chosen to read. The difficulty — which I call “readability”.
I also created two lists of books: one for the books that most secondary pupils had chosen to read, and another for the books they had voted as their favorites. According to the readability, these students’ favorite books tend to be much more advanced than the other books they chose, but they could still understand them. The rest of the books most often chosen by them are quite simple.
You might think that students who read harder books might make more mistakes and understand them less well. But students’ quality of comprehension does not depend on the difficulty of the book, no matter what year of secondary school they’re in. Having an interest is the most obvious factor here — if you like the book, you try hard to really understand it.
As children become teenagers, they listen less to advice from adults and more to advice from kids of their age. So, rather than trying to lecture young people on the benefits of Jane Austen, we should make the nature of the problem clear to them. Students should challenge each other to read more difficult books. Adults could help by setting up noticeboards or organizing social media networks for young people to share their recommendations. And teachers can lend a hand by setting aside time for reading in school. Young people will realize the problems that come when they don’t challenge themselves to read difficult books.
1.What can we learn from the first paragraph?
A.Children spend little time on after-class reading
B.Secondary school students seldom read tough books
C.Children’s reading interest tends to decrease as they grow up
D.Primary students have difficulty choosing good reading materials
2.The author made use of AR software to ________.
A.understand children’s different reading styles
B.show the average time children spend on reading
C.find out the causes of children’s reading difficulties
D.make clear the difficulty levels of books read by children
3.What can we infer about secondary school students from the readability scores?
A.They find some advanced books interesting
B.They often make mistakes during advanced reading
C.They prefer to read books recommended by their parents
D.They can hardly improve their scores on reading comprehension
4.According to Paragraph 4, what is vital for improving reading comprehension?
A.Basic knowledge
B.Reading skills
C.Motivation
D.Instruction
5.What does the author want to express in the last paragraph?
A.Designing relatively difficult textbooks is necessary
B.Improving students’ reading is a shared responsibility
C.Advanced technology should be used in reading reaching
D.Students should be encouraged to read more literary works

We may not be aware of it, but ordinary family homes in the U.S. and the rest of the world are not energy-efficient.
Most of their energy goes to heating and cooling, and a lot of it is wasted, as warm air and cool air escape through fireplace chimneys and thin or poorly fitting windows and doors. A passive house loses almost none."Imagine a thermos(保温瓶),"said housing developer Brendan O’Neill."You have insulation(隔绝) everywhere, and it’s basically completely sealed. And so the idea is to build a house like a thermos. So the windows are sealed. There’s insulation completely surrounding the building. We make it as sealed as possible."
A 147-square-meter passive house, presented by O’Neill Development Corp. as a demonstration unit just outside Washington, was brought to the site in two boxes. "Once it’s set and put together, it takes about four weeks to complete the outside construction, to put down carpets," O’Neill said. "If everything is set in place, you put a house like this together in about four months.”The total cost of building it was $325,000, or about 17 percent more than constructing an ordinary house. But its utility(公用事业) bill is only around $20 monthly, or one-tenth the amount for the average house of the same size.
While passive houses have been around for a long time, the idea has never taken root in the U.S. There was no driving force to push it.
However, David Peabody, an architect who designs passive houses said, "I think climate change is now becoming a larger issue. And I think building standards are catching on to that. So people are becoming more aware of energy."Peabody said the cost of building passive houses could come down."What really makes sense for truly affordable housing," he said, "is to build multi-storey buildings."
1.Why aren’t ordinary family homes energy-efficient?
A. Building them wastes much energy.
B. Their energy mainly goes to heating and cooling.
C. Their sealing performance is poor.
D. They have no insulation around at all.
2.What is the feature of a passive house?
A. There’re no windows or chimneys.
B. There’s little space to place furniture.
C. Its building cost is relatively high.
D. It takes about four weeks to build one.
3.What’s David Peabody’s attitude to the future of the passive house?
A. Cautious. B. Optimistic. C. Skeptical. D. Concerned.

If you are a sleep deprived(被剥夺) teacher, you may not be aware of the term woodpeckering(啄木鸟式点头), but you’ve probably done it. It happens the day following a bad night’s sleep. You’re sitting in a long meeting and you can barely keep your eyes open, so you support your head up with your hand. Next thing you know, you are moving your sleeping head back to its upright position. Do this a few times and you are woodpeckering.
I thought I knew sleep deprivation when I did my medical internship(实习) in hospital. That year I frequently went 36 hours with no sleep. When I finished my stay in neurology(神经内科), I welcomed the promise of full nights of sleep ever after. It went pretty well for the next 10 years until I became a school teacher and experienced a whole new level of sleep deprivation.
Teachers’ working hours go far beyond the 8 am to 5 pm schedule of kids in school. There are hours spent at staff meetings, correcting homework, preparing for the next day- and then there is the worrying. What I did in a hospital emergency room required no more intensive mental energy than what is need to keep 30 kids attentive enough to learn what I was teacher.
Good teachers are like magicians keeping a dozen balls in the air to come at right time, with alarm set for 6 am to finish grading papers, memories of the day that’s gone- including the students who didn’t understand something, forgot their lunch or were embarrassed by wrong answers. All these will become sleep-resistant barriers. And also with some financial stress, you’ll have a cycle of insomnia(失眠) with unwelcome consequences.
With inadequate sleep comes irritability(易怒), forgetfulness, lower tolerance of even minor annoyances, and less efficient organization and planning. These are the very mental useless that teachers need to meet the challenges of the next day. In wanting to do a better job the next day, the brain keeps bringing up the worries that deny the rest it needs.
1.After a bad night’s sleep, usually the direct effect for the next day is to ______.
A. keep one’s eyes open all the time
B. move head back and forth
C. raise one’s head in upright position
D. keep nodding like a woodpecker
2.The writer’s new level of sleep deprivation began since he _____.
A. did his medical internship in hospital
B. began to teach in a school
C. left hospital ten years ago
D. went 36 hours with no sleep
3.From paragraph 3 we can infer that ____.
A. teachers’ work is comfortable
B. correcting homework needs less time
C. working in hospital is even tougher
D. teaching needs more mental energy
4.Good teachers’ sleep problems are mainly due to the _____.
A. common sleep-resistant barriers
B. embarrassment for wrong answers
C. diligence and devotion to teaching
D. misunderstanding of their students
5.What does the writer really want to tell us in the last paragraph?
A. Unfavorable effects of inadequate sleep are various
B. Lay down worries and sleep well first for the next day.
C. Teachers should often practice mental muscles.
D. Better job has nothing to do with inadequate sleep.

Everybody knows that Coca-Cola is red, and Starbucks is green. 1. What we may not be aware of is the science behind these companies’ choices of these colors.
Color psychology is the study of how colors affect people’s mood, behavior, and decision-making. Companies use color psychology when they develop their brands and advertisements in order to persuade us to buy.2.
3. For example, it’s no accident that many tech products use white; it’s simple, stylish, and clean. Meanwhile, cosmetics companies tend to go for purple, black, or pink colors that represent passion, luxury, and romance.
Companies often choose action colors that urge you to buy right now. Red, for instance, is a high-energy, exciting color that moves people to action. Yellow is the color of summer, and it’s bright and attention-grabbing.4.
5. Studies show that consumers prefer brands that they recognize. Thus, those with an established color scheme, such as LEGO or Facebook, are likely to perform more strongly on the market.
All this goes to show that successful companies have mastered the art of color psychology. It may seem trivial, but their choice of colors has a profound effect on the spending habits of consumers.
A .Based on this, companies create fancy names for colors to make them sound special.
B. In fact, studies have shown that around 90 percent of people base their spending choices on color and appearance.
C. It’s no wonder that McDonald’s decided to use these two colors for its branding.
D. Chances are that most of us can name companies and their respective brand colors.
E. In fact, most major companies are associated with certain specific colors.
F. Because of this, companies use colors to influence how we feel about their products.
G. This is why, for example, Estée Lauder uses names like “passion fruit” and “hot rocket” for its lipsticks.
