The word“day” has two meanings. When we talk about the number of days in a year,  we are using “day” to mean 24 hours. But when we talk about day and night,  we are using“day” to mean the time between sunrise and sunset. Since the earth looks like a ball,  the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning（旋转）of the earth. At the equator（赤道）day and night are sometimes the same length（长度）. They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock in the evening. For six months the North Pole is tilted（倾斜）toward the sun. In those months the Northern Hemisphere（半球）gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.

The world is not hungry，but it’s thirsty.   1  while we say we are short of water.Why？Because about 97% of water on the earth is sea water which we can‘t drink or use for watering plants directly.Man can only drink and use the 3% of water that comes from rivers and lakes.   2  ，because some of it has been polluted.

　　Now more water is needed.The problem is how we can avoid a serious water shortage in the future.  3 Scientists are making study in this field.Today，In most large cities water is used only once and then runs to the sea or rivers.but it can be used again.Even if every large city reused its water，the water will still not be enough. 4 .

　　The sea seems to give us the best answer.There is a lot of water in the sea.All that needs to be get the salt out of the sea water.This will be expensive，but it has already been used in many parts of the world.   6 So you see，if we can find out a way，we’ll be in no danger of drying up.

Basketball is still a young game. It's over a hundred years old. In the winter of 1891, a certain college was having some trouble with its boy students. The weather was bad and the students had to stay indoors. As they couldn't play outdoors, they were unhappy, and some even got into fights from time to time.

　　Some of the teachers, at the college asked Dr. Naismith to invent a game so that the students might have something to play with. It was not easy to invent such a game because it had to be played indoors , and the court (球场) was not very large.

　　Dr. Naismith thought for a few days and invented a kind of ball game. It was a fast, wonderful game with much moving and passing of the ball. It was played between two teams. To make a score , the ball had to be thrown into the basket ten feet(英尺) above the floor on the wall . At each end of the court there was such a basket. At first, Dr. Naismith wanted to throw the ball into a box. As he could not find boxes of the right size, he had to use fruit baskets instead. That is how the game got its name.

阅读短文，根据意思，判断所给句子的正误。正确的写T，错误的写F。
“How are you?” is a nice question. It’s a friendly way that people in the U.S.A greet（问候） each other. But “How are you?” is also a very unusual（不寻常的） question. It’s a question that often doesn’t need an answer. The person who asks“ How are you?” hopes to hear the answer “Fine”, even if the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine” isn’t really an answer. They are simply （只）other ways of saying “Hello” or “Hi”.
　　Sometimes, people also don’t say exactly（确切） what they mean. For example, when someone asks “Do you agree?”, the other person might think, “No, I disagree. I think you’re wrong...”But it isn’t very polite to disagree so strongly（强烈地）, so the other person might say “I’m not sure.” It’s a nicer way to say that you don’t agree with someone.
　　People also don’t say exactly what they are thinking when they finish talking with other people.For example, many talks on the phone finish when one person say “I’ve to go now.” Often, the person who wants to hang up（挂）says: “Someone’s at the door.” “Something is burning (烧)on the stove（炉）.” The excuses（借口） might be real（真的）, or not. Perhaps the person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite, and it doesn’t hurt （伤）the other person.
　　Whether they are greeting each other, talking about an idea, of finishing a talk, people don’t say exactly that they are thinking. It’s an important way that people try to be nice to each other, and it’s part of the game of language.
【小题1】“How are you?” is another way of saying "Hello." or" Hi."
【小题2】It is polite to say" No. I disagree. I think you are wrong, "if you don’t agree with others.
【小题3】When someone says "I have to go now "On the phone，it means he wants to go on talking.
【小题4】"Someone is at the door." may be an excuse for finishing a talk.
【小题5】Sometimes people don't say exactly what they are thinking about just because they try to be nice to each other.

Dear Reader,
Imagine an 11-year old girl whose days are often spent washing clothes, looking after a baby, working hard in the field.
Imagine a little girl who knows there will not be enough food for dinner, who can’t fill her stomach with water because it’s polluted, and who has watched life slip away from her father, little brother and sister because the family is too poor to see a doctor.
Is it hard to believe? For Maria Pastora, these are the real life.
Maria would gladly walk miles to school, but her mother, now alone, needs her badly at home. If Maria grows up without any schooling, what will be her future?
But for just 52 pennies a day, you can sponsor a child like Maria. Through “Save the Children”, you can help Maria’s mother get the tools and ways she needs to turn their poor food into a good dinner and the money she needs to buy clothes and school things for Maria.
To help Maria most, your money is put together with that of other sponsors, so hard-working people can help themselves. Build a school, a hospital…bring in clean water. This is what “Save the Children” has been about since 1932.
For you there are many rewards. Have the chance to write to or hear from your sponsored child. Receive photos or progress reports. Know you are reaching out to another person. Not with a handout(施舍物), but a “handup”. That’s how “Save the Children” works. But without you, it can’t work. Please take a moment now to fill in and post the form below to help a child like Maria and her village.
It can make such a difference in her life and yours.
