Picking up objects plays an important role in people’s life. El-E is a robot that is designed to get everyday objects for people with disabilities.

About 1.5 meters tall, with a single robotic arm that can pick up objects at different heights, El-E is equipped to discover what its owner wants and then go and fetch it. The user can point a location to the robot using a “point-and-click” way of interaction, which provides a direct way to tell the robot which object to handle or where to go. The robot can adapt the position of its arm in order to grasp the object.

After successful early trials, some scientists expanded El-E’s functions and tried to combine voice commands with the laser (激光) in order to do more complicated tasks, like opening doors. The robot recognizes words such as “pull” or “push” and performs the action on an object illuminated by the laser. In order to add more functions, project director Prof. Charlie and his colleagues are focusing on programming El-E to locate and fetch common household items such as a hairbrush, a bottle of pills or a cell phone.

The robot is also designed to learn from its mistakes. “If it fails to fetch an object, it will recognize it and try again,” Charlie said. Formal studies have shown El-E to be a good worker. In 127 out of 134 trials, the robot successfully picked up the requested object.

1.What is the purpose of the text?

A. To describe different types of El-E.

B. To predict the development of El-E.

Fahad Azad, an engineer in India, invented a robot named DuctBot．The toy-car sized DuctBot measured 23 centimeters in length, 19 centimeters in width and 9 centimeters in height and weighs just two kilograms．

The robot is designed to snake through dark, narrow air conditioning ducts （管道） and clean them．A pair of LEDs fitted on the robot light up the dirty scenery, so it can be captured （抓拍） by a camera．

In order to control it more easily, Mr. Azad chooses to fix DuctBot on wheels．The robot can clean off lots of dirt, as well as dead pigeons and insects．Keeping indoor air in good quality and monitoring carbon-dioxide levels in buildings with central air conditioning is a challenge．It is important in some places where clean air can mean a difference between life and death, such as hospitals．Dirty air has a bad influence on people's health．

EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad's invention in a national newspaper after he had won an international robotics competition．EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work．Across India, for example, the task still falls to children．They are small enough to go through those ducts．

In 2005, Mr. Azad who was still at university decided to do something about it．Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners．

Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage （污水）pipes．Their biggest challenge is to make the robots user-friendly enough．Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers．There will be lots of difficulties they need to overcome in the future．

1.What can we learn about Ductbot?

A．It is a toy car and popular with children．

B．It is designed to move like a snake in the ducts．

Scientists have created a “ human-like robot” that can dance and do the housework.

“ Mahru” has been developed to imitate humans and can move its lips, eyebrows and pupils(瞳孔). The machine can also move its upper and lower body freely and automatically stop itself when walking.

In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions.

The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind.

“‘Mahru’ will open the way for the commercial use of humanoid robots doing housework,” You Bum-Jae, leader of the development research team ,said. “‘Mahru’ can dance while walking on its legs and is able to work in place of a human.”

Through an advanced motion capture (捕获) system, “Mahru” can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking.

State-funded KIST showed the robot during a presentation at its head office in Seoul.

People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves.

The research team added that they had designed another “ Mahru”, this time with sensors(传感器) allowing it to distinguish(分辨) between faces and objects.

The showing of “ Mahru” came a week after researcher in Japan said they had created the “most human-like” robot in the world. A team at robotics department of Osaka University in Japan claimed that “ robogirl”, Repliee R-1, “ looks, moves and interacts (相互作用) like a human, and has silicone(硅胶) skin that feels almost human to the touch.”

1. “Mahru” made by KIST can do the following things EXCEPT____________

2. According to what You Bum- Jae said in Paragraph 5, his research team wants to ________.

3. When Mahru” meets something in its way, it will be likely to________.

高二英语单项填空简单题查看答案及解析

Look and listen, and that concert poster just might be singing. Engineers have designed antennas（天线）that can turn everyday objects, from posters to clothing, into radio stations. Anyone walking or driving by can tune in and hear what’s on. The devices use radio waves, but they don’t generate their own. They hijack（劫持）the same waves that carry music and news to your smartphone.

Vikram Iyer co-led the project with Anran Wang, a graduate student in computer science and engineering. The two got the idea for their invention by paying attention to what was already around them. “It’s the ideal way to minimize the power consumption for any kind of communication,” notes Iyer. Their research had focused on new types of wireless communications that won’t require much energy. They wanted something that would work outdoors in a city. Then they realized the air is already filled with wireless communications in the form of radio stations.

Radio waves carry energy at the speed of light from tall transmission towers to radios in cars, phones and homes. These waves of the antennas take in existing radio waves and change them slightly. Those changes add new sound information. The changed waves are then sent back out into the world where people can listen in. So the device only needs enough power to change the waves, not to generate them.

The scientists tested their device with a poster. It advertised a Seattle concert by Simply Three. People standing almost 4 meters away from the poster could use FM receivers on smartphones to listen to all songs of the band’s music, Those in cars as far as 18 meters away could use car radios to pick up some parts of the songs

The technology could even extend to clothes. Iyer, Wang and their team turned the shirt into an antenna. It let the shirt talk to the wearer’s smartphone. If a sensor in the shirt tracked a person’s heart rate during exercise, for instance, the antenna could transmit those data to the wearer’s phone.

1.The underlined word “generate” in the first paragraph is closest in meaning to “　　　　 ”.

A. promote　　 B. repair　　 C. produce　　 D. recycle

2.Which of the following is one advantage of the new antennas?

A. They save energy.

B. They are small-sized

C. They can be used in villages.

D. They can improve radio signals.

3.What is the third paragraph mainly about?

A. The way the antennas take in radio waves.

B. The working principle of the antennas.

C. The benefit people can get from the antennas.

D. The situation where the antennas can be used

4.What can be inferred from the text?

A. The antennas can be available at present.

B. Vikram Iyer created the antennas with much money.

C. The antennas cannot be used in the students dormitory and classroom.

D. The closer people stay to the antennas, the stronger signals they pick up.
