Napoga is a 12-year-old girl in Ghana, 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 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 on the earth.
Water covers 70% of the earth’s surface. 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. Something must be done to prevent water form be­ing polluted.
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 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!

任務(wù)型閱讀 （共5小題；每小題2分，滿分10分）
閱讀下面短文，根據(jù)短文內(nèi)容回答問題，并按要求完成第105題。
Should Shanghai bid for(申辦) the Summer Olympics in 2028? Here are some people’s opinions.
Some people said, “The games will improve Shanghai’s global influence and the city is powerful and must try to become a platform(平臺) for major international dialogues. Shanghai has succeeded in holding the World Expo in 2010 and the city can also hold a successful Summer Olympics.”
Others, however, are not sure that it’s a good idea. They think the Olympics would be too expensive and the money could be better spent on other things.
The 2008 Beijing Olympics brought much prestige(聲望) to the city and to China, but its cost, over $40 million, was high and the Olympic site(場地) in the center of the city is now largely unused. Could Shanghai learn from Beijing’s experience and do it better?
My answer is yes. As one American said, “A great city has to do great things.” Shanghai is a great city and is not afraid of facing challenges. Holding the 2028 Summer Olympics would prove that.
小題1:When did Shanghai hold the World Expo?
小題2:Why don’t some people agree to bid for the 2028 Summer Olympics?
小題3:How much did the 2008 Beijing Olympics cost?
小題4:Does the writer agree to Shanghai’s bidding?
小題5:請將劃線句子翻譯成漢語。

When your pen is broken, you think that’s the end of its life. You throw it away. It then joins tons of other garbage that is becoming a big problem in cities.
Each day, about 10,000 tons of waste is produced in Guangzhou, and 17,000 tons of household waste is produced in Beijing.In other countries, the case is similar.“If you’re like most of us, most Americans, you’re making seven pounds (3.17kg) of trash a day,” US writer Edward Humes told CNN. So, an American makes 102 tons of trash in a lifetime.
If you simply throw away that broken pen, it goes to a landfill(垃圾填埋場) and is buried together with many other trash. To prevent polluting the groundwater, workers cover the trash with soil and keep it dry. And your pen will stay there for a long, long time, without having further use.
But it could have a better destination: the recycling bin.Have you ever noticed the different colors of trash bins in the street? Many cities in China have been running a waste-sorting (垃圾分類) campaign. They divide trash into “recyclable waste” and “unrecyclable waste”.
Recycling waste can save energy, reduce greenhouse gas, and keep space free for the unrecyclable trash.Take your pen as an example. At the recycling factory, its metal parts could be taken out and reused to make other things.But recycling is not enough, experts say. Making less waste in the first place is the way forward.
“The best thing to do is just keep using your stuff for as long as you can,” US writer Adam Minter told Time Out magazine.

Have you ever been sad because you failed in something? If so, please remember, for often, achieving what you expect is not the most important thing. Enjoy the process(過程). Here is a story to tell you why.
One day a little boy decided to dig a hole behind his house after watching a science program. As he was working, a couple of boys stopped by to watch. “What are you doing?” asked one of the visitors. “I want to dig a deep hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that it was impossible to do it. Then they left.
The little boy kept on digging and digging. Suddenly, a few small colorful stones caught his eyes. He collected them and put them into a glass box patiently. Humming a song, he went on digging. The box was full soon. Then he talked to himself quietly and proudly, “Maybe I can’t finish digging all the way through the earth, but look at what I have found in the process of digging!”
The boy’s goal was too difficult, but it did cause him to go on, in other words, to cause us to keep working.
Not every goal will be achieved. Not every job will end up with a success. Not every dream will come true. But when you can’t achieve your goal, maybe you can say, “Yes, but look what I’ve found along the way! There are so many wonderful things that have come into my life because I tried to do something!” It is in the digging that life is lived. It is the unexpected joy on the journey that really has a meaning.
小題1: Is achieving what you expect the most important thing in the passage?
小題2: When did the little boy decide to dig a hole behind his house?
小題3:Why did the older boys begin to laugh at the little boy?
小題4: What did the boy find in the process of digging?
小題5: What does the writer want to tell us?

It is well-known that everyone has his own dream as well as his own future. But do you know what future really is? I have to say that future is now. That is to say, we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
There is an old English saying: “Gain time, gain life.” Then what’s time? Time is something that we can’t see or touch, but we can feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeable. We always say “Time is money,” but time is even more precious than money, because when money is spent, we can earn it back. But if time is gone, it well never return. So some of us even say time is priceless.
We should always remember: Future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today. We should do everything before us as well as possible. And never put off what can be done today till tomorrow.
As we all know, “Time and tide wait for no man.” If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember: “No pains, no gains.” Today’s hard work is the cause of tomorrow’s harvest.
根據(jù)文章內(nèi)容，補全下面句子，每空一詞。
