THIS summer, many Beijing middle school students had a different kind of vacation. Instead of hanging out with friends or traveling, they were training hard for the National Day celebration.
To mark the special anniversary (周年纪念)of China this year, the students performed a group dance in a big parade(游行)on Tian’anmen Square on October 1.
Students were training from 7:30am to around 10:00am or from 4 pm to 6:30pm. It was to avoid the summer heat.
They wore white hats, T-shirts and dark-blue trousers. The hats and T-shirts were printed with a red logo, the number ‘60”.
The first week of training was PE. Students practiced standing and squatting（蹲)。 Then they moved on to practice the group display. The use colored sheets in the shape of flowers as a prop(道具). When we watch the parade on TV we will see them making colorful patterns(图案)with them.
What do the students think of their unusual summer?
“Sometimes we find it a bit tiring.” says Lu Wenqi,13.”But most of us think it’s a great honor to take part in such an important celebration.”
Li Hui, 15, thinks the same as Lu. She says her classmates are seldom late for training.
“It’s a wonderful chance for us,’ says Li. “When my parents were in college, they also took part in a national day celebration. Now it’s my turn!”

basketball or riding home from school. A cold drink may
be just the thing. But be careful what you are drinking.
Something that looks cool may not be good for your health.
There are plenty of "energy drinks" on the market. Most of
them have beautiful colors and cool names. The lists on
them tell you they are helpful to your health. Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.
Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited( 限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

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 news 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(印刷) 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.

Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.
Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
小题1:From the passage we learn that locusts________.
| A．are small animals | B．are easily found by birds |
| C．are dangerous to their enemies | D．change their colors to protect themselves |
| A．They run away quickly. | B．They have the colors much like their enemies. |
| C．They hide themselves by day and appear at night. | D．They have to move quietly. |
| A．they have the colors much like the trees | B．they move quietly |
| C．they like brown and gray colors | D．they live in forests |
| A．Because it is very and strong. |
| B．Because the liquid it sends out can help it escape from its enemies. |
| C．Because the liquid it sends out can kill its enemies. |
| D．Because it swims faster than any other fish. |
| A．The Change of Colors for Animals and Pests | B．Colors of Different Animals and Pests |
| C．The Main Use of Colors for Animals and Pests | D．Some Animals and Pests |
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”
小题1:The purpose of Beck and Edwards’ study is to _____________.
| A．understand human-animal relationship |
| B．make lonely old people’s life better |
| C．find the causes of old people’s loneliness |
| D．improve the animal-assisted research |
| A．note the activities of AIBOs |
| B．keep AIBOs at home for 12 weeks |
| C．record their feelings and activity |
| D．study the collected information |
| A．moves again | B．is movable | C．doesn’t need | D．need |
| A．It is easier to keep at home. |
| B．It can help the disabled people. |
| C．It responds to all the human orders. |
| D．It can watch TV with its owner. |
| A．cure certain diseases | B．keep old people active |
| C．change people’s ideas | D．look more like real dogs |
