In a world where nearly 6 million fingerprint records of government employees are stolen in one computer hack, and where millions of people are victims of identity theft every year, the next step in cyber security may well be mapping your brain.

Researchers at Binghamton University, State University of New York arc working on a biometric （生物特征 识别的）system that records how your brain reacts to certain images. With a little more polishing, the scientists' brainchild could become the way you get into a safe deposit box, your office or past scanners at the airport. It could replace the password for your online banking, your email or your social media accounts.

They started their project by measuring the brain waves of 30 subjects. The subjects were fitted with a cap that had 30 electrodes （电极）attached to it, and then shown various images and symbols — celebrity faces, words, pictures of food --- on a computer screen in 200-millisecond bursts. The brain\ reaction was recorded.

The idea is that every time a person needs to use a “password", he or she goes through the same procedure, and the results are matched with their first-time reaction. If the "brainprint" is compromised --- like what happened with the fingerprint records --- then the system is merely reset by running another set of images and collecting a different set of brain waves。. "Even if that was stolen, you could just cancel it and record one to something else", says professor Laszlo.

Laszlo and her team have shown that their system can be 100 percent accurate. So one of the more difficult parts of making the system practical already has been overcome. Now, they're spending much time recording accurate brainprints with as few as three electrodes, which could make recording in the future as easy as wearing a pair of special glasses. They're also working with cheaper materials and different methods to see if they can bring the cost down.

1.What does the underlined word "brainchild" in paragraph 2 refer to?

A.The brain function. B.The fingerprint record.

C.The online password. D.The biometric system.

2.Why were the images and symbols shown to the subjects?

A.To check the brain's reaction.

B.To create their brainprints.

C.To match brainprints with pictures.

D.To connect brain waves to electrodes.

3.What will happen when a brainprint fails?

A.A new one will be set

B.A spare one will be made ready beforehand.

C.The users' identity will be stolen.

D.The fingerprint record will replace it.

4.What are the researchers doing with the program now?

A.Improving its accuracy.

B.Recording more brainprints.

C.Making it user-friendly.

D.Increasing the number of electrodes.

The London Underground is one of the best transport networks in the world with around 24 million journeys made each day, so it is important that everything runs smoothly. Remember the following to travel like a Londoner.

Keep right on escalator(自动梯）

The tube network is very busy during the rush hour. You can expect the trains and stations to be overcrowded between 7:30 and 9:30 in the morning and between 17:00 and 19:00 in the evening.

Move down the platform to find more space

高二英语单项填空简单题查看答案及解析

The National Gallery of Art in Washington, D.C., is one of the world's greatest art museums. Millions of people have entered its doors to see paintings by the world's fine artists. But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully. The Gallery's 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem.

In past times, the owners of paintings did not protect them from damaging changes in humidity (湿度) and temperature. As a result, the life of these paintings were shortened. In the National Gallery, however, humidity and temperature are carefully controlled. The building is air-conditioned in summer and heated in winter. The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system. If one should fail, the extra one can take over.

Light is another enemy of paintings. Ultraviolet rays (紫外线) in light cause paintings to fade (褪色).  Long ago, paintings often hung in dark churches and palaces. A coat of varnish (清漆) was a protection from the weak light. But when museums took over the care of many paintings, they were often hung in brighter light than before. Soon they were in danger of fading. The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age.

To protect its paintings, the National Gallery put a special kind of glass in its skylights. This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays. The Gallery has also developed new and better varnishes which help to keep paintings from fading. Thanks to these new precautions, many of the world's greatest paintings are being well protected for future generations to enjoy.

1.The text mainly tells us about ______.

A．the guard force in the National Gallery

B．protecting great paintings from nature

C．priceless paintings of past times

D．the air-conditioning and heating systems in the National Gallery

2.The underlined word "precautions" in Paragraph 4 is closest in meaning to ______.

A．decorations

B．problems

B．you can touch these paintings while you are in the National Gallery

C．the care of the world's greatest paintings is both a big responsibility and a great challenge

D．the guard force in the Gallery has not done a good job

More than one million children in the United States do not go to school. Instead, they learn at home. Most often, their parents are their teachers. Educational companies, libraries and the Internet provide many families with teaching materials.

Parents choose home schooling for several reasons. Some choose it because of their religious beliefs. Others say it provides more time for the family to be together.

Over the years, the American public education system strengthened and grew. By the 1960s and 1970s, however, some Americans believed that traditional education was not helping their children. So a number of parents began home schooling.

Home schooling expert Linda Dobson says many people have helped the movement grow. She says many kinds of people have joined the movement. These include rich people and poor people.

Ms. Dobson says the number of home-schooled children has increased an estimated fifteen to twenty percent each year during the last fifteen years.

More than one million single-use straws (吸管), most of them plastic, are used in the United States each day. They end up in waterways, harm sea animals, and break down into micro-plastics. Quantities of places have passed plastic-straw bans as a way to start handling the global plastic waste problem.

Straw materials: advantages and disadvantages

1. Metal

Made of stainless steel, aluminum, or even titanium, metal straws have become popular. They draw some criticism for having a metallic taste and conducting heat from a hot drink, but they’re strong and can be reused.

2. Paper

Paper drinking straws, which date from the late 1800s, often absorb liquid over time and can leave a taste or fibers in drinks. They’re the most popular throwaway choice in places with plastic-straw bans.

3. Glass

Though glass straws may be more breakable and thus less portable than reusable straws of other materials, they hold up well to washing and reuse. Some straws are made to look artistic, with colors and blown-glass designs.

4. Bamboo

This natural material can be sustainably produced and is a plant-based replacement of plastic straws. Bamboo straws are easily disposed of and turned into fertilizer. They are reusable but can be hard to clean completely and may absorb flavors.

1.What is the major problem with plastic straws?

A.Function. B.Flavor.

C.Weight. D.Pollution.

2.Which of the following belongs to single-use straws?

A.Metal straw. B.Paper straw.

C.Glass straw. D.Bamboo straw.

3.What is the advantage of the bamboo straw?

A.It can become fertilizer. B.It is easy to clean.

C.It is portable and bendable. D.It has different designs.
