    Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometers long and 240 kilometers wide. It is a very important island because it is completely made of sand. In fact, it is the largest sand island in the world. There is no airport on the island, but there is a long beach along the east coast. Planes arrive and leave from here.

    The sand makes unusual shapes. There are hills made of sand called sandblows. Nothing grows on them. They move one or two meters a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island, such as Rainbow Gorge, The Cathedrals and Red Canyon, the sandy rocks have different colors. Sometimes the rocks are so brown that they turn the sea brown, like coffee.

    Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests—eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.

    About 500,000 people visit the island every year to see the island's beauty and nature. People enjoy camping and hiking（徒步）there. Unluckily, the visitors create problems. They damage plants and frighten animals. Their sun cream（防晒霜）makes the water dirty. So it is necessary to manage the visitors. For example, people may not use motor boats or go fishing in the lakes, and they need official papers to drive there.

    It's March, 2050.

    Frank and Mary Smith wake up in their comfortable house in the morning and switch on the bedroom computer to get the latest news.

    They used to read the Times, but changed to electronic newspapers many years ago.

There is the usual news about space: another space flight has returned from Mars and scientists have discovered a new planet. Then they turn to business news: the US dollar has risen greatly in Shanghai, one of the world's leading business centers. Mary tells the computer to buy 5000 dollars, and there is a quick response that it has been done.

As they watch the screen, Mary orders one of the household robots to make coffee for them. Frank disappears into the study to join a video conference with his partners around the world. He is a computer engineer, working for several companies. This is his third job: he used to be in marketing and then television.

    Mary has a quick look at the shopping channels--the usual selection of electric cars, household robots and cheap travel offers before picking up the video phone to talk to her assistant. She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2014 they decided to move to the seaside and work from home.

    Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them: communications systems have made it much easier to learn at home.

    Louise, now thirteen, is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They communicate by computer.

    According to the family doctor, Louise will live to at least 130. Her wish is to work for a few decades(十年) and then spend her time on music and painting.

    Water is a liquid (液体) ; but it can also be a solid when it is very cold and turns to ice. It can also be a gas, when it evaporates (蒸发) and become water vapour (水蒸气) .

The water cycle

    Water is very important, and without it life on Earth would be impossible. The oceans that cover three quarters of the Earth's surface can be thought of as our great water reservoirs. All the time, water is being evaporated from the ocean's surface by the warmth of the sun. High in the sky this water vapour, turns into clouds which drift (漂浮) over the land, often creating rainfall. As the rain falls,it seeps (渗漏) into the soil and then into rivers that flow back into the oceans, where it is ready to begin all over again!

下面是被打乱的有关The water cycle（水循环）的信息，请根据短文内容重新排序。首句己给出：

Water is warmed by the sun and turns into water vapour and rises into the sky.

    North American black bears are shy animals. They are fearful by nature, and will usually run away if they see or hear people. Because of this, it can be difficult for scientists to learn about these animals.

    In order to study black bears, researchers from New Jersey, the US, catch bears and use drugs to help them go to sleep. Researchers then work out the size and the weight of the bears, take blood, to test for diseases, remove a tooth and take it to the lab to find out its age. From these studies, researchers want to find out how many bears live in New Jersey, how long they live, and how many babies they produce.

    But in Minnesota, the US, researchers study bears that are completely awake. The bears know the researchers' voices and they are not afraid of the research team. With the help of a few grapes to keep the bears busy, researchers can touch them to check their hearts, look at their teeth, and do other jobs. Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives."

    In both places, the main purpose is the same—to make sure there is a healthy population of black bears. But the research methods and the kinds of information that researchers are able to collect are quite different.

I'm Bob. I work at night from Monday to Thursday. So in the daytime (白天), I often sleep for at least 7 hours. Then I get up, have some food and watch TV. I usually watch TV for more than two hours every day. At 7:00 p.m., I go to work by bike.

But on weekends, my life is different. I usually sleep at night and do different activities in the daytime. For example, last weekend was quite full for me. On Saturday morning, I went to learn dance. I have dance lessons once a week. In the afternoon, I went to play basketball with my friends. We played for three hours and felt excited. I thought it was good for my health. On Sunday morning, I drove to the dentist for teeth cleaning. In the afternoon, I went to the movies with my friend, Tom. I thought the movie was interesting, but Tom thought it was difficult to understand (理解).
