A new keyboard can tell whether you are its owner. The keyboard records information about the typing pattern（模式）and sends it to a computer program. The program then checks to see if the pattern matches the right user. If not, an alarm sounds, and the computer locks the typist out. It locks out everyone else, even if the person knows the password. What's more, this equipment needs no batteries. It collects all the energy it needs from your actions of typing. Besides, the keyboard is also self-cleaning and the keys are free of damage from water, oil and dirt.

The keys of the new keyboard are made of the same inexpensive plastic that might be found on any other standard keyboard. But instead of being smooth, the keys have millions of tiny plastic nanowires（纳米线）on their surface area, increasing the effective contact areas between the plastics and fingers. This guarantees that there's enough power to run the keyboard as someone types.

Liming Dai, a scientist, did not work on the new keyboard, but he thinks the design could be important in getting better performance from a variety of equipment. "It could also be applied to a touch screen, for example, "Dai says. " Then smart phones and notepads could collect energy from someone's actions of typing or drawing. "

"Future work might make the keyboard even more useful, "Dai adds. " A later design might build tiny capacitors onto the nanowires, "he suggests. Capacitors are little devices that temporarily store electric charge. Those might then be LEDs to light a keyboard in the dark.

Zhonglin Wang is a co-designer of the new keyboard. His team has built a working model of the keyboard. "If a company decides to fund（资助）its production, this keyboard could be in stores in as few as two years, "says Wang.

Anvitha Vijay，who is only nine years old，has built two educational apps. One is Smartkins Animals，which helps many 【小题1】（child）identify more than 100 animals and 【小题2】 other is Rainbow Colors，which teaches kids colors.

With the help of YouTube videos，the young girl from Melbourne，Australia，learned codes（编码）at age 7 all by 【小题3】（she）. Soon，she was trying her hand at making apps.“When I first got my iPad，I 【小题4】（attract）immediately by all the apps on it，”she told TFK.“It wasn't long 【小题5】 I wanted to create my own.”

Anvitha's skills won her a scholarship to attend a big tech conference hosted by Apple in San Francisco，California. There，she got tips from the professionals and went to workshops 【小题6】 she learned about the latest software for app building. All that training led to an idea for a third app. This one，called GoalsHi，inspires kids 【小题7】（develop）good habits.

Anvitha's goal is to keep on 【小题8】 (create) technology that helps kids learn while they are having fun. But what's even more 【小题9】 (importance) to her is that the world sees the power of technology in kids' hands.“The more training we get in tech at an early age,”she says,“the 【小题10】 (good) chance we will have of becoming champions who will one day change the world.”

   Trying to fight against the nation's food waste problem，Denmark opened the world's first supermarket that sells expired（到期的）or damaged products.

Ever since it was opened in Copenhagen，people have been standing in line outside WeFood for a chance to buy discounted items that would otherwise have ended up being rubbish because of damaged packing or very short use-by dates. Food，cosmetics，and other household items at WeFood are priced at least 30% to 50% lower than those at regular stores.

It's foolish to throw away or let food go to waste," said Hansen, former Minister for Food and Environment." It's bad for the environment and obviously it is money spent on nothing. A supermarket like WeFood makes so much sense and is an important step in the battle to fight against food waste."

While Denmark alone is said to waste about 700,000 tons of food this year, the United Nations has stated that globally, food waste adds up to 1.3 billion tons. It is really shocking, considering that about795million people in the world are still short of food. Denmark, however, has taken measures. As a result, it wastes 25% less food than it did five years ago.

The We Food project is cooperation between the Food Bank and Dan Church Aid. Together they have collected over s 150，000 over the past years. They faced many problems while convincing the government to permit the sale of expired or damaged products. They were finally allowed to carry out the project，and the store is now specially run by volunteers. The money it earns is used to provide funds（基金）for Dan Church Aid's other projects in developing nations.

If We Food can successfully maintain its goods deliveries and remain popular in the long term，Dan Church Aid plans to open many other branches across Denmark.

【小题1】According to the second paragraph，the items sold at We Food are _____________.

A．second-hand	B．unique
C．popular	D．perfect

【小题2】The We Food project is aimed at _____________.

A．helping the developing countries

B．turning all the rubbish into treasure

C．earning more money to expand the supermarket

D．attracting more people to buy their waste products

【小题3】What is the main problem We Food is faced with now？

A．Finding more volunteers to carry out the project.

B．Making sure they have plenty of items for sale.

C．Opening branches of We Food around the country.

D．Getting permission to sell expired or damaged products.

【小题4】Which of the following is the best title of the passage？

A．People stand in line outside We Food for food

B．We Food becomes the world-famous supermarket

C．Fighting against the problem of food waste in Denmark

D．The world's first expired or damaged product supermarket

   A solar-powered car that can be charged as it runs is being tested in Germany.

Munich-based manufacturer（制造商）Sono Motors has built the new type, named Sion, and will likely help the European powerhouse hit its national target of 1 million electric cars on the road by 2020.

Sono Motors has solar cells fixed into Sion’s bodywork, with a total of 330 solar cells built into the roof, bonnet and sides of the vehicle. These enable the vehicle’s battery to be charged when sunlight is hitting the solar cells, whether it is on the road，or parked in the sunny spot in a car park.

The solar-powered vehicle is set to be launched in Germany in 2019.

Sono Motors wants Sion to be universal and allows the car to be charged using solar energy as well as conventional outlets（电源插座）, so car owners aren’t left on cloudy days.

The firm has made a 2019 date for mass production，which will be undertaken by a European manufacturer. Some 6,500 people have already placed orders for the electric vehicle. Prices for Sion tend to start from € 16,000 next year. The all-electric vehicle will offer a range of around 250 km before the battery runs out completely and it needs recharging either by solar power or using a wall plug, the company said.

Sion was designed originally as an environmentally conscious car，but will also include a number of features designed around comfort to help it compete with other modern vehicles.

“We have a seat heater, air conditioning, and a large entertainment system where I can also connect my phone, which means I really have a full vehicle,” Laurin Hahn, co-founder of the company told Reuters.

【小题1】From the third paragraph we can know that ______.

A．the car is popular on the road

B．the car has a very large battery

C．there are 330 solar cells on the car

D．where there is sunlight, Sion can be charged

【小题2】What does the underlined word in Paragraph 4 “launch” mean?

A．design	B．release
C．improve	D．recall

【小题3】Why does the car not break down when it is cloudy?

A．Because it is made from the rainproof material.

B．Because it can be charged by clouds on cloudy days.

C．Because it can store a great deal of energy.

D．Because it can be charged by conventional power outlets.

【小题4】What are the features of the car?

A．Modern, powerful and popular.

B．Environmental, comfortable and competitive.

C．Environmental, cheap and simple.

D．Expensive, fashionable and energy-saving.
