Canadian student Raymond Wang, 17, won the world's largest high school science competition — the Intel International Science and Engineering Fair (Intel ISEF), taking home the top prize of $75,000 for inventing a new way to keep germs from spreading in airplane cabins.
Wang started thinking about the problem of disease spread on airplanes after a steady stream of news about the Ebola outbreak in West Africa. Ebola is not spread through the air, he learned, but other infectious diseases — including the H1N1 swine flu virus and SARS virus — are spread through the air. And that's a problem in airplane cabins, where everyone is breathing everyone else's air. “When someone sneezes, there's a mess everywhere，” he explained.
Wang said he made up his mind to solve the problem when he discovered that few people in the airline industry were actively working on ways to improve the quality of airplane air.
He designed fin shaped devices (鳍形装置) that fit into the airplane's existing air inlets (入口). The fins redirect the airflow, creating walls of air around each passenger. Each person gets a personalized zone of fresh air, and sneezes are pushed out of the cabin before they can spread. His invention would improve the availability of fresh air in the cabin by 190 percent. Wang said that it would cost per airplane $1,000 and could be put in overnight. And he's already filed an application for a patent.
Wang is clearly not your average high school student. He did his project not for class but on the side, and he learned what he needed to know pretty much on his own. “This year I have to pick up fluid dynamics (流体动力学)，” he said. “I keep going with it, watching some videos and looking at some papers.”
语篇解读：本文为记叙文。加拿大一名高中生发明了一种能够防止病毒在飞机上传播的装置。

Stop wasting your time thinking of reasons for your failures. Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.
The seeds, and the power to grow them, are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.
You cannot be successful without first developing your self confidence. Your level of self confidence is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self confidence are people who do not believe that they have any power, or responsibility for their lives. They are always victims. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.
You can exercise control over your life only to the degree that you believe you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.
Everything happens as a result of something. If we can identify (确定) the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.
In all areas of your life, whether they are financial, physical, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it. You are on the road to success.
语篇解读：这篇文章告诉我们每个人生来就是可以成功、可以富裕的，那么区别到底在哪呢？在于你是否能够让成功的种子发芽。

A．they fail only because of bad luck
B．they don't make efforts to succeed

Ⅴ.阅读七选五
What will man be like in the future How about in 5,000 or even 50,000 years from now We can only make a guess, of course, but we can be sure that he will be different from what he is today. __1__
Let's give an example. Man, even 500 years ago, was shorter than he is today. Now, on the average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may guess that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity (容量). As time goes on, however, we shall have to use our brains more and more — and finally we shall need even larger ones! __2__ The head, the forehead in particular, will grow larger.
__3__ In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. __4__ At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! __5__ He will still be a human being, with thoughts and emotions similar to our own.
A．This probably brings about mental changes.
B．Nowadays our eyes are in constant use.
C．In spite of all these changes, future man will still have a lot in common with us.
D．This is likely to bring about physical changes, too.
E．That's because man is slowly changing all the time.
F．These, as a result, are likely to grow weaker.
G．As a result, future man will have little in common with us.

EP Portable Heater
We all know that the cost of heating our homes will continue to be significant burden on the family budget. Now millions of people are saving on their heating bills with the EP portable heater. With over one million satisfied customers around the world, the new EP heats better and faster, saves more on heating bills, and runs almost silent.
The EP has no exposed heating parts that can cause a fire. The outside of the EP only gets warm to the touch so that it will not burn children or pets.
The EP will not reduce oxygen in the room. With other heaters you'll notice that you get sleepy when the heat comes on because they are burning up oxygen.
The advanced EP also heats the room evenly,_wall to wall and floor to ceiling. It comfortably covers an area up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. And they only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.
The EP comes with a 3 year warranty (保修) and a 60 day satisfaction guarantee. If you are not totally satisfied, return it at our expense and your money will be given back to you. Now we have a special offer for 10 days, during which you can enjoy a half price discount and a free delivery. If you order after that, we reserve the right to either accept or reject order requests at the discounted price.
Take action right now!

There is a technology that may someday be widely used as a way to identify people. An American doctor can plant a computer chip under his skin which can send personal information to a scanner. The chip gives off information which will be scanned by a hand held reader.
The chip is similar to that planted in more than 1 million dogs, cats and other pets in recent years to track and identify them. The doctor decided to test the chip by himself after the World Trade Center disaster. He thought the dead in the disaster could have been identified if their names and other important information had been chipped.
Officials of the company said they hope to sell the chips to patients with man made arms or legs. The idea is that the chip will provide immediate and correct medical information when needed.
The information can contain name, telephone number and other information. Or it can send out a message that, when connected to a computer, can call up records. The scanner can read it through clothes from over a meter away. The new product also could be used to control prisoners. Workplaces of great importance may want to use the chips for employees too. Some parents may consider planting chips in young children or elderly relatives who may be unable to say their names, addresses or telephone numbers.
Some medical and technology specialists said the product raises new questions about the relationship between humans and computer technology and could cause problems if it is used against someone's wishes, or if personal information is read by those who should not see it.
语篇解读：本文是一篇说明文，介绍了美国一种电脑芯片的研发情况及其前景。
5．In the text, computer chips have already been used to ________.
A．catch escaped prisoners
B．find missing children
C．treat sick people
D．follow lost animals
解析：选D 细节理解题。从文中第二段第一句可知，芯片早已被应用到一百多万只动物身上，以跟踪它们，在它们走丢时找到它们。

A．Because nobody would dare to try it.
B．Because the chip could be used for identification purposes.
C．Because the chip had been proved successful on animals.
D．Because his patients expected him to experience the chip first.

Unit 3 课时跟踪检测（一） Warming Up & Reading — Prereading
阅读理解
A
Brooke Martin's golden retriever (金毛猎犬) Kayla hated being left alone or separated. She would howl, pace, and chew on things. Brooke learned that other people had the same problem with their pets. She wondered：“What if you could talk to your dog if you were gone？”
Working with her father in their garage, the 16 year old came up with several ideas. Finally, she invented a device that allowed pet owners to video chat with their pets! She calls the device iCPooch. “The dog doesn't have to answer the call，” explains Brooke. “It comes up immediately on the screen on their end. It's a two way audio and video — you can see and hear each other.” With a click of a button you can even send the dog a treat!
Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle school students. These finalists, selected based on their short video presentations, are working with mentors over the summer before heading to the final competition in St. Paul, Minn.
After Martin's video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge, she was paired with Delony Langer Anderson, a product development scientist in 3M's consumer health care division. “I just lead her down the product development path，” Langer Anderson told Live Science. This path includes guidance on how to test the potential product, which combines a video chat device that answers immediately on the dog's end with a dog treat device the owner can remotely activate.
“One thing I have thought about a lot is, what happens if while the device is on the floor, what if your dog knocks it over, or scratches the screen？” Martin said. She and Langer Anderson discussed this, and Martin is now testing materials at a local dog shelter by taping them to the dog house floors to see how well they withstand sharp teeth and claws.
The finalists create models they can test, with the guidance from a mentor. Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards drivers for not texting or calling. Langer Anderson tries to help the students work through the scientific method, testing their hypothesis, in a determined way, “so the kids don't get buried in data.” she said.

Here's a good deed you can do without parting with a single thing. Synthetic (合成的) voices for people who have lost the ability to speak only come in generic (一般的) types — think of Stephen Hawking's voice — but one amazing project wants to build custom voices for each person. To do that they need your help: specifically, a recording of your voice.
VocalID is the brainchild of two speech scientists, who are turning their research into a much larger project. Voice is very personal and, like a prosthetic (假体的) leg or arm, it makes sense it should be customized to each person.
Here's how it works — and don't worry, this does not mean someone will be walking around with the same voice as you out there：
After recording a couple of hours of audio in, say, a quiet room with an iPhone, you send it to VocalID, where a program called ModelTalker cuts it up into the basic units of speech that can be recombined as new words and sentences. In that same step, characteristics of the patient's voice — based on what limited sounds they can make — are mixed with the donor's to create a whole new one.
VocalID is still in its beginning stages, and they're looking for help from everyone including voice donors, financial support, and programmers. A priority (优先的事物) is making voice donation even easier, cutting down recording time, especially for kids. But as it stands already, your voice is just about the easiest thing to donate.
语篇解读：本文是说明文。文章介绍了如何给不会说话的人捐献声音。
4．Stephen Hawking's voice ________.
A．has no personal characteristics
B．was donated by a volunteer
C．was created by VocalID
D．sounded amazing
解析：选A 推理判断题。由第一段中的“Synthetic voices for people ...custom voices for each person”可知，史蒂芬·霍金那样的合成语音是一般的类型，而一个新的项目想要为不能讲话的人制作个性化的声音。据此可推断，史蒂芬·霍金的合成语音没有个性特征。
5．To create a new voice, which of the following is/are needed
A．Sounds made by the patient.
B．A few days of audio recording.
C．The voice of at least two donors.
D．ModelTalker that can combine words.
解析：选A 细节理解题。由第四段中的“characteristics of the patient's voice — based on what limited sounds they can make — are mixed”可知，要在捐献的声音的基础上制作一个新的声音，需要患者自己发出的声音。
6．What is the main purpose of the text
A．To introduce some jobs in VocalID.
B．To encourage readers to donate their voice.
C．To advertise a program called ModelTalker.
D．To collect money for people who cannot speak.
解析：选B 写作意图题。由文章开头的“Here's a good deed you can do”及文章末的“your voice is just about the easiest thing to donate”可推断，文章主要是鼓励读者为不能讲话的人捐献自己的声音。

Since Henry Ford turned it into a mass market product a century ago, the car has delivered many benefits. It has promoted economic growth, increased social mobility and given people a lot of fun. But the car has also brought many problems. It pollutes the air, creates traffic jams and kills people. An astonishing 1.24 million people die, and as many as 50 million are hurt, in road accidents each year.
Drivers and passengers waste around 90 billion hours in traffic jams each year. In some car choked cities as much as a third of the petrol used is burned by people looking for a space to park.
Fortunately, a new technology promises to make motoring safer, less polluting and less tendency to hold ups. “Connected cars”— which may eventually develop into driverless cars but for the foreseeable future will still have a human at the wheel — can communicate wirelessly with each other and with traffic management systems, avoid walkers and other vehicles and find open parking spots.
Some parts of the transformation are already in place. Many new cars are already being fitted with equipment that lets them keep their distance and stay in a motorway automatically at a range of speeds. Soon, all new cars in Europe will have to be able to warn the emergency services if their on board sensors (传感器) discover a crash. Singapore has led the way with using variable tolls (道路通行费) to smooth traffic flows during rush hours; Britain is pioneering “smart motorways”， whose speed limits vary constantly to achieve bined, these new inventions could create a much more highly effective system in which cars and their drivers are constantly warned of dangers and showed the ways, traffic always flows at the proper speed and vehicles can travel closer together, yet with less risk of crashing.
In the past, more people driving meant more roads, more jams, more death and more pollution. In future, the connected car could offer mankind the pleasures of the road with rather less of the pain.

7．According to Paragraph 2, the problem of parking has resulted in ________.
A．more time on the road
B．a great waste of fuel
C．even heavier traffic jams
D．increased death and injuries
解析：选B 细节理解题。根据第二段“In some car choked cities as much as a third of the petrol used is burned by people looking for a space to park.”可知，在一些拥挤的城市里，寻找停车位所耗费的汽油占汽油使用量的三分之一，说明停车造成大量汽油的浪费，故选B。
8．What does “a similar effect” in Paragraph 4 refer to
A．Reducing traffic jams.
B．Building smart motorways.
C．Setting proper speed limits.
D．Keeping steady traffic flows.
解析：选D 词义猜测题。根据本段“Singapore has led the way with using variable tolls (道路通行费) to smooth traffic flows during rush hours”可知，新加坡通过使用浮动的道路通行费来疏导车流，英国也正在采取措施来取得类似的效果，故选D。
9．What is the author's attitude towards connected cars
A．Curious. B．Doubtful.
C．Supportive. D．Disappointed.
解析：选C 观点态度题。根据第四段“these new inventions could create a much more highly effective system” 和第五段“In future, the connected car could offer mankind the pleasures of the road with rather less of the pain.”可知，作者认为这种新的发明能创造出一种更有效的交通体制，在带给人们驾车的乐趣的同时，也会减少事故带来的伤痛，说明作者对这项发明是支持的，故选C。
10．Which of the following can be the best title of the text
A．The Future of Cars: Wireless Wheels
B．The Future Traffic Management System
C．The Benefits and Problems of Cars
D．The Promising Future of Car Production
解析：选A 标题归纳题。通读全文尤其是第三、四、五段可知，文章主要讲的是未来的汽车，而不是未来的交通管理系统。故选A。
