Nanda sees a wearable computer as a handbag, one that’s built out of four-inch squares and triangles of fabric (织物), with tiny computer chips embedded (嵌入) in it. It looks, feels and weighs like your typical leather purse.
That’s where the similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf (围巾).
Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices (装置), part of next generation of wearable computers, could become common within a few years. DuPont created new super strong fibres that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.
As a result, these new wearable devices are different from the heavy and silly types of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike the old types, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.
Here’s how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will inform the computer that you’ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are applied in markets like auto repair, emergency services, medical monitoring-and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years—making for a booming market for wearable computers that don’t look like something out of science fiction.

More and more people are annoyed at the continually rising house prices. They want to know who is to blame for it. Local governments, developers and speculators share a vested interest in it. People who are really in need of homes are most likely to suffer heavy losses.
Many local governments depend on selling land to keep its normal operation. The higher land prices, the more money. Therefore, developers back the local governments by buying land at high prices. In return, the governments make favorable policies to help the developers. For example, drive all the possible home buyers to this nasty market. They even encourage large numbers of speculators to catch more people.
Rising house prices have already become the fence which divides the Chinese society. It has caused widespread dissatisfaction. The government will lose the support of the common people if leaving house prices out of control. Besides, rising house prices willstop us building the new country side as the present policy actually forbid people to flow freely from cities to the countryside.
Collecting taxes on houses can fundamentally solve this problem. On one hand, it will discourage the speculators. On the other hand, it will offer a stable tax resource apart from reducing the sales cost of the developers. Secondly, stop the developers selling the houses before completion. If so, the developers will certainly try their best to sell all their houses once completed. And this will also lower speculators' expectation of price rising, which will decrease speculations.The only victims of rising house prices are __________.
| A．governments |
| B．real home buyers |
| C．developers |
| D．speculators |
The local governments reward the developers by __________.

In my profession as an educator and health care provider, I have worked with numerous children infected with the virus that causes AIDS. The relationships that I have had with these special kids have been gifts in my life. They have taught me so many things, but I have especially learned that great courage can be found in the smallest of packages. Let me tell you about Tyler.
Tyler was born infected with HIV: his mother was also infected. From the very beginning of his life, he was dependent on medications to enable him to survive. When he was five, he had a tube surgically inserted in a vein in his chest. This tube was connected to a pump, which he carried in a small backpack on his back. Medications were hooked up to this pump and were continuously supplied through this tube to his bloodstream. At times, he also needed supplemented oxygen to support his breathing.
Tyler wasn't willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard, wearing his medicine-laden backpack and dragging his tank of oxygen behind him in his little wagon. All of us who knew Tyler marveled at his pure joy in being alive and the energy it gave him. Tyler's mom often teased him by telling him that he moved so fast that she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard, she could quickly spot him.
This dreaded disease eventually wore down even the likes of a little dynamo like Tyler. He grew quite ill and, unfortunately, so did his HIV-infected mother. When it became apparent that he wasn't going to survive, Tyler's mom talked to him about death. She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven.
A few days before his death, Tyler beckoned me over to his hospital bed and whispered, "l might die soon. I'm not scared. When I die, please dress me in red. Mom promised she's coming to heaven, too. I'll be playing when she gets there, and I want to make sure she can find me."What is the boy Tyler's attitude towards death?
| A．Pessimistic. |
| B．Optimistic. |
| C．Sorrowful. |
| D．Fearful. |
Tyler requested the writer to dress him in red when he died simply because __________.

Which of the following might serve as a possible title for this passage?

| B．A Caring Mother |
| C．Mother and Son |
| D．Dying in Red |

Students are being forced to take additional exams to get into leading universities because good A-levels do not always indicate the brightest candidates. Sixth formers applying to courses such as medicine and law are being asked to sit American-style aptitude (智能) tests, which are designed to assess (评价) thinking skills, among fears that too many A-level candidates are getting top grades. Last year, almost one in six students applying to universities such as Oxford and Cambridge from independent schools had to sit additional tests to secure a place.
Head teachers criticized the move, which they said would pile more pressure on schools and students. But universities insisted that the reforms were unavoidable, because A-level exams were no longer an accurate barometer (标准) of ability.
In 1986, 40 percent of students starting at Oxford achieved straight As at A-level. Mike Nicholson, its admissions director, said that this year almost every candidate offered a place would get perfect grades. It meant the university had to stage additional tests to identify the most able candidates. "The ability to achieve three A grades is no longer the end-point in the admissions process," he said. "The potential to achieve three A grades will allow them to enter the race for a place."
Oxford is not the only university turning to aptitude tests. At Cambridge, the number of students taking the university's Thinking Skills Assessment shot up 26 percent to more than 3, 000. A survey of 16, 830 sixth formers applying to higher education from private schools last year showed that 2, 860 had to sit at least one exam.
Earlier this year, the National Foundation for Educational Research recommended that most sixth formers should sit SAT tests —a standard reasoning exam widely used in American colleges—to make iteasier to pick out the best candidates.What is the attitude of head teachers to the reform?
| A．Approving. |
| B．Doubtful. |
| C．Opposed. |
| D．Neutral (中立的) |
Which British university first started to use aptitude tests to pick out the best candidates?
| A．Harvard. |
| B．Oxford. |
| C．Cambridge. |
| D．Washington |
What can we know about the A-level system?
| A．It can indicate the brightest candidates. |
| B．It was designed to assess students' thinking abilities. |
| C．It is longer an accurate way to assess students' abilities. |
| D．It was recommended by the National Foundation for Educational Research. |
What can we infer from the passage?
| A．The reform is more popular in American colleges than in British ones. |
| B．The reform will be applied by all universities in the future. |
| C．Universities used to depend on the A-level system to choose the best students. |
| D．Passing additional tests will allow the student to enter Oxford, regardless of whether he or she gets As. |
What is the passage mainly about?
| A．How to get into leading universities. |
| B．The disadvantages of the A-level system. |
| C．Different ways to identify students' abilities. |
| D．Universities using extra exams to choose students. |

"Our aim is to take our art to the world and make people understand what it is to move," said David Belle, the founder of parkour (跑酷).
Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale, Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.
Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour isconsidered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.
Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.
Overcoming all the obstacles on the course and in life is part of the philosophy (理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, "I love parkour because its philosophy has become my life, my way to do everything."
Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.Parkour has become popular throughout the world because of __________.
| A．its founder, David Belle |
| B．the film Casino Royale |
| C．its risks and tricks |
| D．the varieties of participants |
