A passenger(乘客) told an air hostess that he needed a cup of water to take his medicine when the plane just took off. She said to him that she would bring him the water in ten minutes.

The air hostess was kept so busy that she forgot to give him the water. As a result, the passenger was held up to take his medicine. Thirty minutes later, when the passenger’s ring for service sounded, the air hostess hurried over to him with a cup of water, but he refused it.

In the following hours on the plane, each time the air hostess passed the passenger, she would ask him with a smile whether he needed help or not. But the passenger never replied to her.

When the passenger was going to get off the plane, he asked the air hostess to hand him the passenger’ booklet. She knew that he would write down sharp words about her job,but with a smile she handed it to him.

Off the plane, the air hostess opened the booklet, and smiled because the passenger wrote, “On the flight, you asked me whether I needed help or not for twelve times in all. How can I refuse your twelve sincere smiles?”

Dear Tom,
How are you? I’m in a new school this term. And I’m writing to you in my school now. My new school is big and nice. There are one thousand and four hundred students and one hundred and forty teachers in my school. I like the teachers. They are very kind to me. My classmates are very friendly, too. They teach me Chinese and I teach them English.
There are trees, flowers and green grass(青草) in my school. They are very beautiful. Behind my school there is a small river. The water in it is quite clean. We can swim in it.
We have no classes on Saturdays or Sundays. Sometimes I go to play football or basketball with my classmates. Sometimes I stay at home and watch TV. Sometimes I go to shops with my father and mother. We all like China.
Please write to me soon!
Yours,
Jack

The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.
Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we 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.
How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain 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 stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or goes underground.
But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won’t be used up.
【小题1】The world is thirsty for water because _______.

A．we don’t have enough fresh water	B．a lot of water goes into sewer systems
C．only 70% of the earth’s surface is water	D．sea water is widely used rather than fresh water

【小题2】From this passage, we know acid rain _______.

A．is only bad for living things	B．is not bad for buildings and factories
C．can be produced in factories	D．is bad for people, animals, plants and buildings

【小题3】One difficult way we can solve the problem is to _______.

A．use the water with salt in it	B．remove the salt from sea water
C．get water from underground	D．reuse the water in cities

【小题4】What is the best title for this passage?

A．Fresh water and sea water	B．A thirsty country
C．The importance of water	D．The world’s water problem

Summer is coming soon. When is the best time for swimming in the day in summer?
If you would like to swim indoors, a good time in the day is the early hours-the body has the most energy to use because the body has woken up and will be ready for all kinds of different activities of the day. The body is going to work with enough energy and therefore a person will feel more comfortable if he swims during the early hours of the day.
Swimming early in the day can also be good for anyone who plans to swim outdoors. The conditions outside will be excellent: the water will not be too cold or too hot, and the air will be just clean and fine. Everything is suitable.
Usually, it is not a good idea to swim later in the day because one’s body is tired after work for a whole day and also the weather conditions can be the worst in the later parts of the day.
However, there are still some exceptions. Different people feel different and one’s body acts differently at different time of the day. When a person is feeling active and is not tired at all after work, it may be a better time to swim for him than for others. If he is alert(警觉的) that time, he is safe in the water.
In a word, the best time can change for every person. The person’s body condition decides when the best time for swimming is.
