Teamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations (调查) are almost always carried out by teams of people working together. Ideas are shared, experiences are designed, data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone.

Several times throughout the year you may be asked to work with one or more of your classmates. Whatever teh task your group is assigned, a few rules need to be followed to ensure a productive and successful experience.

What comes first is to keep an open mind, becasue everyone’s ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Choose a role on the team that is best suited to your particular strengths. Thirdly, always work together, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual support and trust often make a great difference.

Activities like investigations are most effective when done by small groups. Here are some more suggestions for effective team performance during these activities: Make sure each group member understands and agrees to the task given to him or her, and everyone knows exactly when, why and what to do; take turns doing various tasks during similar and repeated activities; be aware of where other group members are and what they are doing so as to ensure safety; be responsible for your own learning, though it is by no means unwise to compare your observations with those of other group members.

When there is research to be done, divide the topic into several areas, and this can explore the issue in a very detailed way. You are encouraged to keep records of the sources used each person, which helps you trace back to the origin of the problems that may happen unexpectedly. A format for exchanging information (e.g. photocopies of notes, oral discussion, etc.) is also important, for a well-chosen method not only strengthens what you present but also makes yourself easily understood. When the time comes to make a decision and take a position on an issue, allow for the contributions of each member of the group. Most important of all, it is always wise to make decisions by compromise and agreement.

After you’ve completed a task with your team, make an evaluation of the team’s effectiveness ― the strengths and weaknesses, opportunities and challenges.

Life in space will certainly take some getting used to！But the space station has been designed to keep the astronauts as comfortable as possible—the modules(舱) are roomy，bright，and kept at a constant 70 degrees Fahrenheit.It’s important the crew members are comfortable because they’ll be busy aboard the station.In a typical workday，crew members will spend 14 hours working and exercising,1.5 hours preparing and eating meals，and 8.5 hours sleeping.Here are some other fun facts about life aboard the station：

Food

Come mealtime，astronauts will have a special dining kitchen.Space food just keeps getting better—and more like food we enjoy here on Earth.In early space missions，astronauts could eat only freeze?dried food that didn’t require any preparation.But the space station is equipped with water，microwave ovens，and refrigerators，allowing the folks on board to eat more “normal” types of food，including fruit，vegetables，and ice cream!

Sleep

Each crew member has a private room.With no gravity，they’ll need to tie themselves to their beds，or they will float away！That might sound like a strange way to sleep，but astronauts from past space missions report that sleeping in space is actually pretty great!

Exercise

You might not think it，but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don’t stand up，sit down or walk in space，so their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this，astronauts on the station will exercise on bikes，rowing machines，and other equipment about two hours every day.

Clothing

Astronauts will have to wear special space suits while traveling aboard the U．S.shuttle or Russian rockets.But once they’re safe inside the space station，crew members can wear regular clothing.Of course，a specially designed，pressurized space suit is required for space walks.It has to withstand(经受住) flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.

Personal Cleanliness

Simple tasks like brushing your teeth can be challenging in a weightless environment.A little water doesn’t flow in a stream—it suspends in a bubble！Astronauts will use a freshwater hose(软管) to take showers，shampoo，and wash off—then a second vacuum hose to suction(吸) off the dirty water.And how do you go to the bathroom in space？With a special “air toilet” that uses flowing air instead of water to dispose of waste.

_______in the ocean, it becomes powerless once it is on the beach.

Australia is the smallest continent in the world. It is a little smaller than China. It is on the Southern Hemisphere(半球)of the earth. Australia is big, but its population is small. The population of Australia is nearly as large as that of Shanghai.
Enough laws have been made to fight against pollution. The cities in Australia have little air or water pollution. The sky is blue and the water is clean. You can clearly see fish in the rivers. Plants grow very well.
Last month we visited Perth, the biggest city in Western Australia, and went to a wild flower exhibition. There we saw large numbers of wild flowers on show, most of which we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. Every year in spring Perth has wild flower exhibitions. After visiting Perth, we spent a day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves very much. When we heard bells ringing at the top of the hill, we looked up, but what we saw made us pick up all our things and run back to our car as quickly as we could. There were about three hundred sheep coming towards us along the path.
Australia is famous for its sheep and kangaroos(袋鼠). After a short drive from any town, you will find yourself among the white sheep. Sheep, sheep, everywhere you can see sheep.
【小题1】Which country is the writer most possibly from?

Trekking through the mists of the Huangshan mountains , I came upon a young man painting the scenery with traditional brush and ink on rice paper. He smiled proudly as he showed me his work. It was indeed quite beautiful for a painting , but it paled compared to the living scene before my eyes: mountaintops surrounded by light clouds, an endless dance of wind and fog that changes alternately in the dark hills beneath. How futile it must feel for a mere human being to try to capture that , I thought.
Yet for centuries ,these mountains in the heart of China have been a destination for artists and poets , who come to commune with nature in one of its more striking pose-and struggle to replicate its beauty. Along with the artists and poets come lovers ,who grasp locks symbolic of their undying love to the chain fences that protect hikers from the steep cliffs .Seventy miles of trials wind around 72peaks , the two majestic of which are Capital of Heaven and Lotus Flower.
In 1990 ,UNESCO declared Huangshan a Cultural and Natural Property , thereby ensuring that the area’s physical beauty will be preserved forever. Pheasant and deer abound. Hundreds of plants are said to heal the body and the famous hot springs are known for their healing qualities . An hour’s meditation in one of these pools is a great way  to end a day of hiking .
The three staging areas for Huangshan visitors are Jade Screen, the Hot Spring area and the North Sea. The Xi Hai and Bei Hai ,located on different summits are three-star hotels serving Chinese and Western food as well as wine and liquor from East and West.
Huangshan may not be exactly off the beaten path , but it is on a road well worth taking.
