Can you imagine keeping an alien dog as a pet? This is what happens in CJ7-the so-called "first
Chinese sci-fi (科幻) movie". It came out in January, 2008. The movie is about a poor man Ti, his son
Dicky and their alien dog CJ7. Dicky, a 10-year-old boy, lives a poor life with his father Ti, a worker.
One day, his father discovers a ball in the trash and he gives it to Dicky. The ball becomes a cute alien
dog. It's a small dog with big eyes and green hair. It can talk and do magic. Soon the dog comes to love
Ti and his son. It goes to school with Dicky. It makes him laugh, but it makes trouble, too. When Ti falls
off a building and dies, CJ7 saves his life. Because the dog uses up all its power(能量), it becomes a doll. But Dicky still wears the dog around his neck. He hopes that CJ7 will come back to life one day.

     Cell phones are all around us. We use cell phones to call our friends, send text messages, play
games, and even take photographs. Now imagine using your cell phone to call your air conditioner. If
this were possible, you could tell your air conditioner to turn on before you got home. Does this sound
impossible to you? Well, it could become possible sooner than you think. In the near future, we might
use cell phones as remote controls for the electrical devices in our homes.
     People are already working to develop different ways to communicate wirelessly with devices we
use every day. For example, it is already possible for cell phones to communicate with laptop
computers. Business people using laptops during meetings can use their cell phones as remote controls.
They can use their cell phones to send instructions to computers to turn on, change pictures, and turn
off.
     With the same technology, people can use their cell phones to control other devices. You can call
your stereo to play music automatically. You can call your lights to turn on when you enter a room.
Maybe even by next summer you will be able to call your air conditioner!

     Now there are many thousands of computers all around the world. Some of them are big and some of them are
small.  They are very useful . People can use them to send and get e-mails,   look for   things on the Internet, play
computer games ... But in 1946 the first computer in the world cannot do these things. It is for calculating. It is as
big as a room! Only some scientists can use it. Some people say the first computer is in China. Why do they think
so? Because the first abacus(the oldest calculating machine) appeared much earlier in China than the big computer
in America.

     Most animals only have animals of a different kind for food. But sometimes two kinds of animals come
  together in a partnership (伙伴关系) which is good for them. You may have noticed some birds on the
 backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄
 生虫) on sheep. The sheep let the birds do so because they can stop the parasites from troubling them.
 So though they can do with it by themselves, they can do better together with each other.
     Sometimes an animal has a plant partner. The relationship develops until the two partners cannot do
 without each other. This is so in corals (珊瑚) of the sea. Inside their bodies they have very small plants,
  which act as "cleaners", taking the useless things from the coral and giving oxygen in return. That is what
 the animal needs to live. If the plants are killed, or are even kept from receiving light so that they cannot
 live as usual, the corals will die.
