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.

If you go to visit London, you’ll see a lot of buses and cars on the road. You’ll also see many bikes because more people travel by bike. Why? There are many reasons. First, it is very cheap to buy a bike, and it is quick, too. You often need to wait for a bus for half an hour. When the bus comes, there are so many other buses and cars on the roads, so the bus moves very slowly.
I travel to work by bus for about four years. I often arrive at work late and feel tired. Then one day, a friend of mine says, “I go to work by bike. Why don’t we travel together?” “Because my bike is old, and there are so many buses and cars on the roads. I’ll feel frightened.” I answer. “Don’t be afraid, if you follow me and we ride slowly, you’ll be fine.” he says.
Later, I buy a new bike. We go slowly, but we arrive at work quickly. I spend 40 minutes going by bus, but only half an hour by bike! Now I love riding a bike. And I feel healthy. Many people think my idea is good and maybe you’ll see more bikes on the road in the future. I travel to work by bus for ________.
| A．one year | B．half a year |

Do teenagers in small villages do chores at home? How about the teenagers in big cities? Here is a survey. We asked 4,000 teenagers in China several questions. Half of them come from big cities like Beijing, Shanghai and Guangzhou. The others are from small villages. We made a diagram of the result of our survey. Let’s have a look at it. We found out that teenagers from small villages do more chores than those from big cities. Maybe it is because they live a harder life. Our advice to parents in big cities is that parents should give their children some chores to do. Doing chores teaches teenagers to take care of themselves.

For many people the subject of hiccups (嗝) is a joke, but for Harry Mendes, a fifteen-year-old schoolboy from Birmingham, it was something quite different.
His hiccups began one Sunday lunch time and continued day and night for two weeks. After the first week, Harry's parents took him to hospital, but it took another week for the doctors to cure his attack.
Harry, who is now back at school, described what happened to him.
“When I began to hiccup, I drank a glass of water but that didn't do any good. That evening I had hiccups every four seconds. We tried everything to stop them. I held my breath and drank cold drinks. My father even tried to give me a shock but that didn't work either.”
After a week of sleepless nights, he went to hospital. The doctors took an X-ray of his chest but they couldn't find anything wrong.
“They gave me some medicine and my hiccups slowed down, but it was another week before the medicine worked completely and my hiccups stopped.”
Harry was very lucky. The world record holder is the American farmer Charles Osborne, who hiccupped for sixty-eight years. He stopped in 1990 at last, but nobody knows why.Harry's hiccups lasted ____.
| A．a week | B．fourteen days |
| C．twenty-eight days | D．one month |
His hiccups started after he ____.
| A．drank a glass of water | B．went to hospital |
| C．ate an Indian meal | D．finished his homework |
