If your pen broke at school today, what would you do? You would go to a shop and buy a new one. What if you could simply print out a real, working pen with your 3-D printer without leaving your room?
Ten years ago people could only see 3-D printing in science fiction(虚构的) movies. But now 3-D printing is here and it’s bringing big changes.
Unlike normal printing that can only copy a 2-D picture with ink(油墨),3-D printing can build almost anything made from material. The printer layers(分层) the material in different shapes to create the object you want to be copied.
The 3-D printer has been used to make many different things. People have made cups cars and even an airplane with it.
Doctors have been using 3-D printers for several years. People’s nervous systems (神经系统)have been printed out in 3-D form medical research. Some body parts have been printed and used in hospital. Several months ago, doctors used a 3-D printer to rebuild the face of a person who had a bad accident. In the future, it is expected(期待) that the printer will make human organs(器官) to save more lives.
However, there are drawbacks to the printer. At the moment, printing can be quite slow and it’s still rather expensive. The average(平均的) price of a household printer is around $1,700,not including the cost of the materials.
But as the technology develops, disadvantages will be improved. Only time will tell where this new technology will take us.

What would you do if you had an accident in your daily life?
It is important for you to get some knowledge about first aid in your daily life. If a person has an accident, he / she needs medical care before a doctor can be found. When you give first aid, you must know three things:

When a person is bitten by an animal, wash the wound with cold running water before he / she is taken to see a doctor. When a person is burnt, wash and cool the area of the skin under the cold tap for a while, then put a piece of dry clean cloth over the burn. If a person is badly burnt, take him / her to the doctor. If a person cuts his / her finger, clean it and put a piece of clean paper round the cut.
In the future we should learn more about first aid and try to spread (传播) it.

What would you do if you found a snake in your house? Many people might be afraid or try to kill it. However, if you live in North Carolina in the USA, one thing you can do is to call the Snake Catchers.
The Snake Catchers are four men who love snakes, even poisonous ones. Their newspaper advertisement says, “Snake Catchers: free snake removal(除去)一Please do not kill them — Call us. ”
The Snake Catchers, who started their service in 1998, don’t charge anything for helping people. “We do this as a hobby,” explained Fred Johnson, one of the Snake Catchers.
Because of their love of snakes, the Snake Catchers try to keep them alive. “One man asked us to kill a python(蟒蛇), so he could make a pair of boots from the skin. We refused, because we like snakes, and we don’t want to see them killed, ” said Fred.
Some of the snakes that they catch are kept as pets; some are given to the North Carolina State University. Most, including the poisonous snakes, are set free in the wild, usually in a national park.
Fred suggests that people should treat snakes with care. “Actually snakes are very shy and gentle creatures. They only attack if they are frightened. However, you have to know how to treat a snake properly!”
According to one happy family, the Snake Catchers are good. One day, the Greenwood family found a snake skin in the kitchen. They looked very carefully and saw a snake sleeping behind a cupboard. They thought about what to do. Then Steve Greenwood remembered the advertisement for the Snake Catchers. He called them.
“The Snake Catchers arrived within an hour and they finished the job quickly too,” said Steve Greenwood. “One of them went into the kitchen, found the snake and took it out alive. The Snake Catchers did a very good job.”
Last year, the Snake Catchers removed more than seventy snakes from houses in North Carolina.
1.The Snake Catchers catch snakes because ______.
A.they want to kill the snakes |
B.they like trying to catch snakes |
C.they don’t want people to hurt snakes |
D.they like eating snakes |
2.When a man asked them to kill a python, the Snake Catchers ______.
A.made some boots from the skin | B.were very happy |
C.gave him some old boots | D.did not agree |
3.The Snake Catchers set most of the snakes free ______.
A.in a national park | B.in a university |
C.in a garden | D.in their own houses |
4.According to Fred, ______.
