Cheaters called “pirates” often use camcorders(便携式摄像机) and cell phones to make illegal copies of blockbusters(大片) in the local theater. These pirates then sell those recordings on the street or over the Internet for very low prices. Some share them for free.

“It’s unfair for people to pirate movies, ” says 15-year-old Hadaia Azad Ezzulddin. Movie piracy “takes money out of the pockets of thousands of people in the movie industry,” she notes. Victims include famous actors and directors as well as local theater owners and their employees.

Hadaia came up with an idea that could help stop movie piracy. Hadaia’s idea uses infrared(红外线的) light. This range of light is invisible to the human eye. It is visible, however, to many types of cameras. Theater owners could place small infrared lights on their movie screens. The lights would not disturb people watching the movie. It would, however, distort the recordings made by many types of cameras.

To test her idea, Hadaia built a box with a movie screen inside. Then, she projected images on that screen through a hole in the box. She took recordings of those images, using nine different types of cameras. These included the types found in cell phones as well as camcorders. During some tests, she also turned on light emitting diodes(发光二极管), or LEDs. The LEDs were embedded(植入的) in a certain place behind the movie screen. They gave out infrared light.

Sure enough, she showed, a pirated movie included odd stripes or spots if it had been recorded while the LEDs were on. It might be possible to use the LEDs to flash the date and time on the movie screen. The information would then appear in the illegal recordings. Theater owners or police might use the information to track down the pirates.

Cutting down on piracy might get more people into theaters to watch the real movie instead of an illegal copy. Six out of every ten films now produced aren’t profitable. They don’t make enough money to recover how much was spent to make and market them. Such a poor payback can discourage filmmakers from producing anything but the types expected to become blockbuster hits. It might also keep smaller theaters from showing a wider variety of movie types.

D. protect the eyesight of viewers in the darkness

3.What is the correct order of the steps in Hadaia’s test?

a. She projected pictures on the screen.

b. She used cameras to record the pictures.

c. She turned on the LEDs placed behind the screen.

d. She made a special box with a movie screen inside.

A. bacdB. bcadC. dbacD. dcab

4.According to the last paragraph, we can know that _______.

A. small theaters often choose to show low-cost movies

The global population is living longer,and getting older,which presents new challenges. “The question becomes:who will take care of everyone? While people will always be the best caregivers for people,there just aren’t enough people. That’s where robotic technology can really make a difference,” says Professor Maja Mataric at the University of Southern California.

Her group is developing robots to work with stroke (中风) patients and elderly people. The research team has found that people react well to a robot gym instructor,and seem to get less frustrated with it than with instructions given on a computer screen. The robot can act as a perfect trainer,with infinite(极大的) patience.

“People say things like ‘I prefer this robot to my husband!Can I take it home?’” according to Professor Mataric. “In fact there’s a really important point here. As we create these care giving technologies,we’re helping not only the people that need the care,but also the people caring for them. We can give them a break,and help them avoid burnout.”

People are going to have to like,and importantly trust robots before they welcome them into their homes,and several groups around the world are working on making it easier to communicate with them.

Much of human communication takes place through body language. Gestures, eye contact , and concepts of personal space are all things that robots are being taught. In learning about how people interact(互动) with machines,researchers are also discovering new roles for robots in our lives. Robots can communicate with humans in ways that other technologies can not.

“If someone finds the robot to be more persuasive and more reliable,that’s going to affect how they interact with it,” says Dr Cynthia Breazeal, director of the Personal Robots Group at the Massachusetts Institute of Technology. “We can now start to think about fields where it’s the social interaction,which is the main means by which a robot helps someone.” Dr Breazeal says that means robots could be used in education,learning,and health care,where social support is important.

1.Professor Maja Mataric mainly focused on robots’ function of ________.

A.teaching B.exploring

C.making things D.giving care

2.Why can robots be wonderful trainers in the gym?

A.Because they are more clever.

B.Because they give correct instructions.

C.Because they cost less money.

D.Because they are more patient.

3.The underlined word “burnout” in Paragraph 3 probably means “________”.

A.feeling tired B.feeling angry

C.getting hurt D.becoming disappointed

4.The scientists are presently working hard to help robots .

A.to use less electricity B.to communicate better

C.to react more quickly D.to have more functions

I always felt sorry for the people in wheelchairs. Some people, old and weak, cannot get around by themselves. Others seem perfectly healthy, dressed in business suits. But whenever I saw someone in a wheelchair, I only saw a disability, not a person.

Then I fainted(昏倒)at Euro Disney due to low blood pressure. This was the first time I had ever fainted, and my parents insisted that I rest for a while after first aid. They said to me, “Never mind!” I agreed to take it easy, but as I stepped toward the door, I saw my dad pushing a wheelchair in my direction! Feeling the color burn my cheeks, I asked him to wheel that thing right back to where he found it.

I could not believe this was happening to me. Wheelchairs were fine for other people but not for me, as my father wheeled me out into the main street, people immediately began to treat me differently.

Little kids ran in front of me, forcing my father to stop the wheelchair suddenly. Bitterness set in as I was thrown back and forth.

”Stupid kids! They have perfectly good legs. Why can’t they watch where they are going?” I thought. People stared down at me, pity in their eyes. Then they would look away, maybe because they thought the sooner they forgot me the better.

”I’m just like you!” I wanted to scream.” The only difference is you’ve got legs, and I have wheels.”

People in wheelchairs are not stupid. They see every look and hear each word. Looking out at the faces, I finally understood: I was once just like them. I treated people in wheelchairs exactly the way they did not want to be treated. I realized it is some of us with two healthy legs who are truly disabled.

D.Don’t hurry.

2.The author once when she was healthy.

A.helped disabled people

B.looked down upon disabled people

C.imagined herself sitting in a wheelchair

D.saw some healthy people moving around in wheelchairs

3.The experience of the author tells us that .

A.life is the best teacher

C.life is so changeable that nobody can foretell

D.one should not do to others what he would not like others to do to him
