Cheaters called “pirates” often use camcorders(便携式摄像机) and cell phones to make illegal copies of blockbusters 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.
1.From what Hadaia says in Paragraph 2, we can infer that _______.
A. most people spend less money on pirates moves
B. the pirates don’t have to pay for the movie tickets
C. theater owners will increase the price of movie tickets
D. she strongly criticizes those who video movies in the theater
2.Infrared lights are put on the movie screens to _______.
A. adjust the brightness of the movie screens
B. make sure the images of movies are dark
C. make illegal copies of movies unpleasant to see
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. d c a b B. d b a c
C. b a c d D. b c a d
4.According to the last paragraph, we can know that _______.
A. forty percent of movies now are profitable
B. small theaters often choose to show low-cost movies
C. more and more people go to theaters to fight movie piracy
D. filmmakers prefer to produce ordinary movies than blockbusters

Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.
Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.
Since 1960 a new kind of tool has appeared. This is the silicon chip -- a little chip of silicon crystal. It is smaller than a finger nail, but it can store more than a million "bits" of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. They will even talk and play games with us. People will have plenty of spare time. But what will they do with it?
Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years
from now?
1.From paragraph，we can know .
A. why early human beings cut skin from dead animals
B. how early human beings discovered the tools
C. what early human beings used the tools for
D. what food early human beings stored
2.The stone chip is thought to be the most important tool because it ______.
A. was very important to the development of mankind
B. led to the invention of machines in the early time
C. developed cooking abilities of mankind
D. was one of the first tools of mankind
3.The silicon chip is mentioned in the passage to________.
A. show the changes of tools
B. introduce a new kind of tool
C. give an example of using tools
D. compare the effects of two kinds of tools
4.At the end of the passage the author seems to suggest that life in future is ______.
A. Out of order B. Less colorful
C. hard to predict D. full of meanings

I have a funny story to tell you: On receiving my learner driver license a couple of months ago, I started driving lessons straight away. However, it wasn’t until two days ago 1. Dad finally allowed me to drive on the motorway. Our destination was Orewa, a seaside 50 km away.
That morning I made sure I had enough to drink and went to the toilet about three times before we left. I thought I was totally prepared 2. the journey, but I had never thought of my family’s 3. (complain).
“Relax! Don’t hold the steering wheel(方向盘) so 4. (tight),” called a nervous voice from the backseat.
“Speed up. 70 km/h isn’t fast enough. You are holding up 5. traffic,” another voice ordered from the seat next to mine.
How 6. (annoy)! To content them I stepped hard on the accelerator(油门), and within a second, an angry voice began to yell again.
“Stop! Slow down, slow down! Are you crazy? Did I tell you to go above 100 km/h?”
Finally I drove into the city, 7. the speed limit was only 50 km/h.
My family seemed 8. (relax) and stopped telling me what to do. They all looked out of the windows and enjoyed the scenery.
On our way home, the journey was much 9. (easy) than before as everyone else fell fast 10. (sleep). So, I just took my time and enjoyed the drive.
