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
小题1:What causes waves?| A．Earthquakes and nothing else. | B．Only wind. | | C．Wind causes most waves. | D．Wind causes some waves. |
小题2:Which of the following is TRUE according to the passage?| A．The water of a wave moves away across the sea. | | B．The water of a wave remains almost at the same place. | | C．The water of a wave goes with the passing of the wave. | | D．The length of a wave means the distance from the top of a wave to the bottom. |
小题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?| A．The wavelengths of the two are equal. | | B．The wavelength of Wave 1 is 10 times longer than that of Wave 2. | | C．The wavelength of Wave 2 is longer than that of Wave 1. | | D．The wavelength of Wave 1 is longer than that of Wave 2. |
小题4:Where can we find this passage?| A．music magazine | B．fashion magazine | C．scientist magazine | D．sports magazine |

Can animals do work for us? Some scientists think that animals may do a lot of jobs. They say that we may see many elephants, monkeys, dogs, bears, and other animals do a lot of things. Animals can get something to eat if（如果） they do some work for people.
Some scientists say that many different animals may do lots of jobs if they know they will get something to eat. Of course, dogs can guard（看护） a house , and elephants can do some heavy jobs.

Do you want to be successful in everything you do? If so, then how? Here is an example.
There was a farmer who 36 corn（玉米）all his life. Each year he took his corn to the market. Then each time his corn was chosen as the 37 and won the first prize.
One year a newspaper reporter interviewed him and learned something surprising about how he grew it. The farmer 38 his seed（做种子的) corn to his neighbors.
"How can you share your best seed corn with your neighbors?" the reporter asked. "You know they are taking part in the 39 with you each year."
"Why, sir," said the farmer, "didn"t you know? The 40 picks up pollen (花粉) from the corn and moves it quickly from field to field. If my neighbors grow 41 corn, cross-pollination (异花传粉) will affect the quality of my corn. So if I want to grow good corn, I must help my neighbors to grow good corn. "
The farmer knows much about the connection of life. His corn cannot improve unless his neighbor"s corn improves.
As a great man says, "We make a living by what we grow; we make a life by what we give." We can"t 42 without food, clothes, and many other things. However, a meaningful life is not decided by how much we can get, 43 by how much we can give others. Giving, instead of taking, makes us 44 from other animals.
So those who choose to live well must help others to live well and those who choose to be happy must help others to find 45 in their life.

When July comes, children know they’ll have the final exams and the school year will end soon. Boys and girls will have a nearly two months’ holiday, and they’ll leave school by train or by car to return home to see their fathers and mothers.
The summer holiday is the best time of the year for most students. The weather is good, so they can spend most of their time playing outside .If one lives in the country, he can go on a trip into the woods or in the fields. If one lives in a big city, he can go to a park to play.
The best place for a summer holiday is the seaside. Some children are lucky enough to live near the sea. But for the others who do not, if they have the chance to stay at one of the big seaside towns for a week or two, they will talk about it all the following school year.
Now, what makes children like the seaside so much? I think it is the sand, the sea and the sun, not anything else. Of course, there are lots of new things to see, nice things to eat and interesting things to do. But the feeling of the sand under their feet, the salt water on their skin, and the warm sun on their backs make them happier.
