Wind is the great maker of waves. There are exceptions (例外), such as the tidal (潮汐的) waves sometimes caused by earthquakes under the sea. But the waves most of us know are caused by winds blowing over the sea .

Now let’s learn some physical (自然地理学的) things about it. A wave has height, from low point to high point . It has length (长度)--the distance from this high point to that of the following wave. The period of the wave means the time it takes for succeeding high points to pass a fixed point. None of these things stays the same--for all depend upon (依靠)the wind, upon the depth (深度) of the water and many other matters.

The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position (原先的位置). And it is lucky that this is so. For if the huge groups of water that make up a wave really moved across the sea, sailing would be impossible. If we want to find the speed of a wave, we may use the following way : Speed =" wavelength" × frequency (频率).

Here, wavelength is the distance between two high points , frequency means the number of cycles per second

1.What causes waves?

2.Which of the following is TRUE according to the passage?

3.The speed of Wave 1 is 100 cm/s, frequency 10. The frequency of Wave 2 is 300, while its speed is twice that of Wave 1. Which of the following is right?

4.Where can we find this passage?

I have worked in Shenyang for two months. I seldom meet Westerners in the street. But on TV, I see many foreigners in Shenyang. I am a little lonely and I really hope to make friends with English speakers. Although I study Chinese hard, my Chinese is poor and I can’t communicate in Chinese very well.

However, Chinese people usually smile and wave to me on the bus and at any other places. In the street, the most common conversation goes like this: A Chinese person, “Hello.”

I, “Hello.”

The Chinese，“Where are you from?”

“England.”

“Oh, I see!” and then if his vocabulary is exhausted(耗尽的), “Bye-bye”. This can happen five or six times on any trip around town. How I hope to see a Westerner at that time.

1.The writer comes from_______.

2.The writer feels________ in Shenyang.

3. Why doesn’t the writer make friends with Chinese people?

5.What is the best title for this passage?   

Everyone needs friends. Friends bring us happiness and hope in our lives. But the ability to make friends changes from person to person. To some people, making friends is easy, and to others it’s very difficult. 
Making friends is a skill, and the first thing is to know how to get along with others.
If you have trouble in making friends, maybe I can tell you how to do it.
★Realize your own good points. You have skills and talents that others will like.
★Believe that you are a good person and have something nice to share with others.
★Be humorous. Learn to laugh at yourself and your weakness. Remember to smile to others.
★Respect others. Everyone has his own idea. Learn how to listen to others’ ideas without trying to make them accept yours.
★Be kind. If you are kind to others, they will usually be kind to you. There are hundreds of little things you can do to show kindness. Open the door for someone. Wave to a friend and so on.
★Don’t complain. Learn to accept what you can’t change, and work hard to change what you can. No one is willing to hear your complaining all the time.
★Never give up. Even if you are faced with some closed-minded people, never give up. And try to find someone who will understand you.

Peter's uncle lived in the country. Once Peter went to stay with him for a few weeks. When they went for a walk or for a drive in the car and they passed somebody ,his uncle waved. Peter was surprised and said, “Uncle George, you know everybody here. Where did you meet them all?”
“I don't know all these people,” said his uncle                
“Then why do you wave to them?” asked Peter.?                 
“Well, Peter,” answered his uncle, “when I wave to someone and he knows me, he is happy. He goes on his journey with a happier heart. But when I wave to some one and he doesn't know me, he is surprised and says to himself, ‘Who is that man? Why did he wave to me?’ So he has something to think about during the rest of his journey, and that makes his journey seem shorter. So I make everyone happy.
