As data and identity theft becomes more and more common， the market is growing for biometric（生物测量）technologies﹣like fingerprint scans﹣to keep others out of private e﹣spaces． At present， these technologies are still expensive， though．
Researchers from Georgia Tech say that they have come up with a low﹣cost device（装置）that gets around this problem： a smart keyboard． This smart keyboard precisely measures the cadence（节奏）with which one types and the pressure fingers apply to each key． The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses． These patterns are unique to each person． Thus， the keyboard can determine people's identities， and by extension， whether they should be given access to the computer it's connected to﹣regardless of whether someone gets the password right．
It also doesn't require a new type of technology that people aren't already familiar with． Everybody uses a keyboard and everybody types differently．
In a study describing the technology， the researchers had 100 volunteers type the word "touch"four times using the smart keyboard． Data collected from the device could be used to recognize different participants based on how they typed， with very low error rates． The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive， plastic﹣like parts． The team hopes to make it to market in the near future．
（1）Why do the researchers develop the smart keyboard？
A． To reduce pressure on keys．
B． To improve accuracy in typing．
C． To replace the password system．
D． To cut the cost of e﹣space protection．
（2）What makes the invention of the smart keyboard possible？
A． Computers are much easier to operate．

The life of an actor appears attractive and many young people dream about becoming one. But the truth is, it is very hard work. If you’re successful, there are deadlines to be met, appointments to keep and the press to deal with. If you’re not successful, then life is extremely tough.
I remember when I started out, I had to search the advertisement board at my drama school every day to look for acting jobs. Drama school was expensive and I needed extra cash to help pay the fees. I welcomed every small job. I played extras in many crowd scenes and became a confident participant in a lot of TV commercials for hair shampoo, soap and washing powder.
I had been working for about two years before I got my lucky break. One day, as I was passing the drama school, I decided to go in to check the notice board. There was nothing on it and I was just leaving when the secretary came along the corridor with a piece of paper. She asked me how I was and I told her life was hard and work was difficult to find. The next moment, she put the paper in my hand and walked away. My hands were shaking as I unfolded the paper, full of expectation. To my surprise, it was an audition (试演) for a clown（小丑）for the Canadian circus. I couldn’t stop myself from laughing. I had expected an audition with a famous director for a new film!
When I was at drama school, there had been a course in acrobatics and clown tricks. I had gained top marks in this course for originality and daring. Later I went to the audition feeling very strange. This was not what I’d had in mind when I enrolled in drama school. To my surprise, the job as a clown turned out to be exactly what I wanted. I loved every moment of getting dressed up and putting on the make-up. I had the opportunity to travel the world and I was more than an actor, I was an entertainer as well. I had visited over 32 different countries and entertained millions of people. The first paragraph is about how _______ it is to be an actor, whether you’re successful or not.

LONDON (Reuters) — Children are dying for lack of drugs tailored to their needs, according to the World Health Organization (WHO), which launched a global campaign on Thursday to promote more research into child medicine.
More than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters.
The problem is even worse in developing countries where price remains a major barrier and 6 million children die each year from treatable conditions.
In the case of HIV/AIDS, the few existing pediatric therapies（儿科的疗法）developed for children generally cost three times more than adult ones.
As a result, clinicians lack clear guidelines on the best drug to use and often have to guess at the correct dose.
Fortunately, the WHO has drawn up the first international List of Essential Medicines for Children, containing 206 products considered safe for children.
“But a lot remains to be done. There are priority medicines that have not been adapted for children’s use or are not available when needed,” said Dr Hans, the U.N. agency’s director of medicines policy and standards.
Medicines that need to be adapted to children’s needs include many antibiotics, pain drugs as well as combination pills for HIV/AIDS, tuberculosis and malaria.
The agency is building an Internet entrance linking to clinical trials carried out in children and will launch a Web site with the information early next year.
Testing medicines on children has always been a controversial issue, since good ethical（伦理的）practice requires informed agreement from people participating in clinical trials, which is difficult to obtain in the case of children.
As a result, research-based drug companies have been wary of developing child-friendly medicines and general companies have been slow to produce them at lower cost.
In an attempt to deal with the issue, both Europe and the United States now have special rules offering extended patent protection for drugs that have been tested on children. Which of the following is the best title of the passage?
| A．A Global Campaign to Promote Research into AIDS Medicine |
| B．WHO Says Children are Dying for Lack of Child-sized Drugs |
| C．Many People are Concerned about Children’s Drugs |
| D．Measures Taken to Develop Child-friendly Medicine Quickly |
Which of the following medicine is not needed to be adapted to children’s need according to the passage?
| A．Pain killers. | B．Tuberculosis. |
| C．AID pills. | D．Flu pills. |
Why has testing medicines on children always been a controversial issue?
| A．It is against good ethical practice |
| B．Children shouldn’t take part in clinical trials. |
| C．It is hard to get informed agreement from children tested. |
| D．Parents don’t allow their children to be tested on medicine. |
The underlined word “wary” in the last but one paragraph means _________.
| A．fast | B．fond | C．cautious | D．uninterested |
What can be inferred from the passage?
| A．There is still a long way to go on children’s medicine. |
| B．An Internet entrance is being built to link to clinical trials carried out in children. |
| C．Both Europe and the United States now have special rules offering extended patent protection for children’s drugs. |
| D．Less than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters |
Online shoppers would rather receive an offer for a product or service than make their own offer 3 according to a study led by a Michigan State University scholar that has implications for the fast-growing e-commerce industry. The findings may come as a surprise given that shopping online is an anonymous(匿名的）process that seemingly can give consumers more confidence to drive a hard bargain,said Don Conlon ，Professor of Management in MSU’s Broad College of Business.
But the study found that participants who made their own offers were less successful in sealing the deal and ，when they were successful? worried they overpaid Many shoppers found the process of researching an offer to be a hassle. “ Americans are very busy，and it’s less time-consuming to be the one receiving the offer rather than the one proposing the offer ” Conlon said. u People tend to be happier when they’re in the receiver role. ”
Online spending in the United States is expected to jump 45 percent in the next four years， from $ 226 billion this year to $ 327 billion in 2017，according to Forrester Research Inc. Nevertheless, researches into this prosperous market remain largely focused on the strategies of companies, rather than those o£ shoppers. Conlon’s study is ，obviously, a rare exception.
Conlon got the idea for the study after considering the difference between two popular sites for hotels and airline flights, priceline.com, which takes bids, and hotwire.com ，which provides offers. Using these two models ，Conlon and his fellow researchers conducted a series of experiments with more than 850 people who were charged with booking a fictional hotel room and acquiring a fictional antique car. Not only did participants prefer to receive bids, Conlon said ，but they also secured more deals in that receiver role. Further ，when they had to make the bids ，they were left more mentally taxed and regretful.
From an industry perspective，putting customers in the receiver role may help fill more hotel rooms and airplane seats. “If you’re a business with a lot of products3 ” Conlon said，“you may want to be the one making the offers. ” However, when selling single items, such as an antique car， accepting bids may be a better option since that typically drives up the price, he said.What can we learn from Para. 1?
| A．The result of the study gives customers more confidence. |
| B．Scholars aren’t surprised at the findings of the study. |
| C．Online shoppers don’t bargain as much as expected. |
| D．E-commerce industry drives more hard bargains. |
It can be concluded from Conlon’s experiments that______.
| A．online shopping is time-consuming |
| B．given prices help promote online sales |
| C．online businesses provide a lot of products |
| D．receiving offers makes online shoppers regretful |
The underlined word “taxed” in Para. 4 probably means______.
| A．burdened | B．numbed | C．relieved | D．challenged |
The passage is mainly about______.
| A．the big advantages of online shopping |
| B．the rapid development of online shopping |
| C．online shoppers’ preference for taking offers |
| D．online companies strategies to improve service |
The early lack of exposure to science ，technology，engineering and mathematics (STEM) can be harmful to achieving gender (性别）balance in these fields. It begins when we are young and continues throughout our time in high school.
While at home，girls generally don’t get to experience the level of exposure or encouragement in STEM fields that their male counterparts do. It is often subtle ，but it’s the first hurdle that faces and confuses so many women. Boys ，on the other hand, get on their path ，and are encouraged to do so， generally earlier than girls. For example ，boys are more often given science sets as toys ，which spark an interest in these subjects.
In school 3 boys are often pushed to take the more challenging math and science classes. So if we want to attract the best and brightest minds into the fields that will advance us as a people ? a country，and a planet，we can no longer look to only half of the population. Young girls cannot possibly consider opportunities they do not know exist. If girls are not exposed to certain subject and career paths，they are highly unlikely to choose to follow them in college.
Our bias(偏见)toward girls9 either from families or from schools ，is so rooted in our culture that we often don’t even recognize it. Although the situation Has changed greatly in the past 20 or 30 years，there is still a sense that girls aren't as good at math 9 for instance 9 even though there is almost no evidence to support such a belief.
It is important that as a society we deal with gender stereotypes long before young people are faced with a decision to declare or choose a major in college. Without making efforts to break them， we are limiting the potentials of our youth，both male and female. Providing the necessary resources， exposure , and encouragement would help young women understand that their gender shouldn’t determine the career path they choose, and that pursuing a STEM career does not make them less feminine.According to the passage ? not many girls grow to enter STEM fields because______.
| A．girls are not as good at STEM as boys |
| B．girls do not like to take science classes |
| C．girls get fewer chances to know about STEM |
| D．girls seldom survive the high pressure positions |
The underlined word “it” in Para. 4 refers to______
| A．our bias | B．our culture | C．the situation | D．a sense |
The main purpose of the passage is to______.
| A．show women’s potentials in STEM fields |
| B．praise women’s contributions to STEM fields |
| C．describe the present gender bias in STEM fields |
| D．call for more involvement of women in STEM fields |
Which of the following shows the structure of the passage?
Your Car Is Ready for Take-off
The flying car has been talked about for many years，but now it appears that the idea is about to become a reality.
An international company has built a two-seater plane that, at the touch of a button ，transforms into a car perfectly suitable for driving on public roads. It has been designed so that the wings fold up automatically； and it takes just 15 seconds to switch between flying and driving. With its wings fully open and the propeller(螺旋桨）spinning, it can take off from any airfield.
Flying cars are quicker than traditional ones for travelling from city to city，and they can run on ordinary fuel. Another big advantage is that they are cool ，like something you would see in an action film. At the moment 9 however, the flying car’s wheels are illegal to leave the ground. That is not because of technical reasons or problems with the design. It is because the various road and aircraft authorities simply cannot agree on whether it is a car or a plane.
“The government and the authorities have never thought seriously about a flying car, says Alan Price ，the president of the company that has developed it. “I wanted a car that could fly and drive ，but it is difficult to find an organization prepared to insure the vehicle against accidents.
Nevertheless ? the company hopes to produce and deliver its first flying car soon. The company already has orders for 40 of them. The majority the potential customers are older and some are retired。There have even been orders from some people who have no pilot's license.
The flying car will cost around $ 200.000. “For an airplane ， that’s a very reasonable price， but for a car, It's quite expensive，” explains Alan. “But it just is not possible to make a $ 10，000 flying car yet. ”
This latest means of transport will not become a mass-market item in the near future，but in the long term it has the potential to change the way you travel. It will become no more expensive than driving your car on the motorway. Travel time could be reduced by more than half.
So the next time you are told to fasten your seat belt, it may be to prepare for take-off.We know from the passage that the flying car______
| A．has to run on special fuel | B．will replace traditional planes |
| C．is popular with the rich | D．can shift between two forms |
The flying car is presently forbidden to take off because______.
| A．many people think driving it not very safe |
| B．it’s hard to decide whether it's a car or a plane |
| C．the government and the authorities don’t accept it |
| D．there are still some technical problems to be solved |
We can learn from the passage that______.
| A．few people will be able to afford a flying car |
| B．flying cars may share the market in the future |
| C．traffic jams will disappear because of flying cars |
| D．driving a flying car doesn’t require a pilot’s license |
