Now satellites are helping to forecast(預報) the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere (大氣), because this is where the weather forms (形成). They send these pictures to the weather stations. So meteorologists(氣象學家) can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead (提前).

There was once a man called Mr. Flowers, and flowers were his only joy in life. He spent all his free time in one of his four glass-houses and grew flowers of every color, with long and difficult names, for competitions (比賽). He tried to grow a rose of a new color to win the silver cup (銀杯) for the Rose of the Year.
Mr. Flowers’ glass-houses were very near to a middle school. Boys of around thirteen of age were often tempted (引誘) to throw a stone or two at one of Mr. Flowers’ glass-houses. So Mr. Flowers did his best to be in or near his glass-houses at the beginning and end of the school day.
But it was not always possible to be on watch at those times. Mr. Flowers had tried in many ways to protect his glass, but nothing that he had done had been useful. He had been to school to report to the headmaster; but this had not done any good. He had tried to drive away the boys that threw stones into his garden; but the boys could run faster than he could, and they laughed at him from far away. He had even picked up all the stones that he could find around his garden, so that the boys would have nothing to throw; but they soon found others.
At last Mr. Flowers had a good idea. He put up a large notice (布告) made of good, strong wood, some meters away from the glass-houses. On it he had written the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble; the boys were much more tempted to throw stones at the notice than at the glass-houses.

Come to Austria!
Soll is a village in the mountains in western Austria, and the Hotel Post, opened by a local (當地的) family, is clean and not expensive. From the hotel you can see the whole village, the forest and the mountains. Temperatures in summer are usually 20℃ to 25℃ in the daytime, but much cooler by evening.
When you visit Bangkok in Thailand, don’t miss the early morning river boat trip to the Floating (漂浮的) Market just outside the city. There you will find many kinds of fruits and vegetables. There you can pay for them when you sit in your boat. Don’t forget your hat: the sun can be strong and it may be as hot as 40℃ about midday!
Maybe the most beautiful place in Hawaii is Kauai. You can visit its long, sandy beaches in the south and west of the island, and mountains and forests in the north, but be careful: there are many mosquitoes (蚊子), and don’t be surprised if it rains in the center of the island. Daytime temperatures there are usually around 24℃ to 26℃ by the sea, and only a little cooler by late evening.
11. If you stay at the Hotel Post, you have a view (風景) of______.

Napoga is a 12-year-old girl in Ghana(加納), Africa. It is hard for her family to get clean water. Every morning, she leaves home at half past five to get clean water for her family in a village far away. It takes her six hours to get enough clean water for daily(日常) cooking and drinking. She has no time to go to school or to play with her friends. Millions of people in the world are like Napoga. They can’t get enough clean water to keep healthy.
Earth Day is April 22. But on all other days, we must also remember it. The water we use is the most important natural resource(自然資源) on the earth.
Water covers 70% of the earth’s surface(表面). But most of that is sea water. We can’t use it for very many things. Fresh water covers only 1% of the earth’s surface.
You probably feel lucky that your life isn’t as hard as Napoga’s. But that doesn’t mean you don’t have to worry about water. We all face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes, and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too. Now, 34% of all kinds of fish are dying out.
How do cars and factories make our water dirty? First, they pollute the air. Then, when it rains, the rain water comes down and makes our drinking water dirty. Dirty rain, called acid rain(酸雨), is also bad for plants, animals and buildings.
Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save more water for ourselves and our children. Here is some advice for saving water:
●Turn off the water while you brush your teeth. You can save as much as 450 liters(升) each month.
●Leaky taps(漏水的龍頭) waste a lot of water. Fix them right away!
●You can easily cut your 10-minute showers(沐浴) in half—and you’ll be just as clean.
●When you wash dishes, don’t let the water run.
●Only wash clothes when you have a lot to wash. If your washing machine isn’t full, you’re wasting water!

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources(資源), we are short of(缺乏) others, for example, fresh water(淡水). It is reported that we will have no coal(煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps(水龍頭) when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.

Christmas Eve means a warm get-together with friends, a candlelight dinner, or perhaps a celebration at a pub(酒館) for students. But, for Cai Yingjie, the night has a different meaning: helping beggars(乞丐) and the homeless(people without homes).
Cai, who is a student in journalism at Tsinghua, could be found at Beijing’s Wudaokou Light Railway Station that special evening. When she saw an old beggar, she took the cold, rough hands of the woman with her warm, clean hands, and gave the woman some warm bread and helped her put on a pair of new gloves(手套).
The woman was surprised for a few seconds, then burst into tears, saying “for the first time I feel respected(尊重)”.
Cai said, “A beggar’s life is very hard. That’s why I want to help them.”
Cai was one of 14 Tsinghua students spending Christmas Eve among the poor. They walked in the cold wind along the streets from 4 to 7 pm on Friday, visiting 15 beggars in Beijing’s Haidian District.
They brought bread and gloves with them, and stopped to greet beggars and offer them some of the warm food. Each beggar greeted them with a look of surprise.
“I know the activity can’t help much, but it’s meant to show our respect and care for beggars and the homeless who have been neglected for so long,” said Sun, head of the group. “And Christmas is a good time for that.”
