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.

Minoru Yamasaki was a well-known American architect (建筑师). He was born in 1912 in Seattle, Washington. His parents came from Japan. Minoru went to college to study architecture. Every summer he worked in a fish factory to help pay for college. Often he worked from four o'clock in the morning until midnight. He slept in a room with 100 other men. Later in life, Yamasaki remembered these times and was always good to his workers.
Yamasaki sometimes dreamed about his work. Once he woke up at three o’clock in the morning. He remembered a building that was in his dream. He got up and started to draw. Yamasaki used a new design(设计) for the buildings. These buildings are now the Century Plaza Hotel, and Tower in Los Angeles, California.
Yamasaki was different from other architects. His buildings give people a feeling of peace（和平） and happiness. Many of his designs have pools of water, flowers, and windows on the roof to let in light. He always designed buildings to please people. He wanted to give them a place away from the busy ways of modern life.
Yamasaki worked for several companies. But his success began when he started his own company. In 1956, he won the Architect’s First Honor Award for his design of an airport in St. Louis, Missouri. He won two more awards (奖)over the next five years. In 1962, he designed the World Trade Center in New York. It is very famous.
In 1993, a bomb exploded (炸弹爆炸) in the World Trade Center. But the buildings did not fall down because they had a good design.
Yamasaki had strong opinions about his buildings. They had to be built his way. He refused to change the design of his buildings, even if he lost a job.
Minoru Yamasaki died in 1986. He designed more than 300 buildings. People will enjoy the design and beauty of his buildings for a very long time.

Imagine the situation. You are driving along in a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device（装置） which uses satellites to find the user’s position. It can find your position to within 20 meters. A GPS cannot start your car, but at least you will know where you are.
GPS, which means Global Positioning System（系统）, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in you pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic （电子的）maps, so you know where you are. For example, in a city they can tell you the name of the street.
There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. the second part is a group of satellites（卫星） orbiting the Earth. The receiver contacts（联系） at least four of the satellites and calculates（计算） its position. The third part of the system is a network of ground stations. They are all over the world. They control (控制)the satellites and make sure they are working well.
Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate（精确的）. There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again..According to the passage, with the help of the GPS, people _________.

The passage is mainly about ____________.
| A．the history of the GPS |
| B．the introduction of GPS |

Every morning, the newspaper chief editor (主编) holds a meeting with the reporters. They discuss the main events of the day. Reporters are then sent to cover (报道) the events.
As soon as the reporters know what to write about, they get down to work. They telephone people and fix a time for a face-to-face interview with them. Sometimes they do telephone interviews. Checking information is very important. They go to the newspaper’s own library to look up any information that they need. This is called “doing one’s homework.”
At the same time, the picture editor decides which photographs will be used for the next day’s paper. All the people who work on a newspaper must be able to work fast. Reporters have to stop working on one story and start working at once on the important new one. They must find out the new information as quickly as possible. Later in the day, everything is put together at the new desk. Reporters return, type their stories into the computer and hand them to the editor.
The chief editor decides which will be the most important story on the front page. Sometimes this will have to be changed if something more important happens late in the day. Other editors read the stories which the reporters have written and make any necessary changes.
Finally, there is no more time left for adding new stories, and the time for printing the newspaper has come. This is done on fast-moving printing machines. The newspapers are then delivered (发送) by truck, plane or rail. Speed is important. People want to buy the latest newspaper; nobody wants to buy yesterday’s.What is the work in a newspaper office like?
