But the waves most of us know are caused by winds blowing over the sea . Now let's learn some physical   things about it. A wave has height, from low point to high point . It has length  --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  the wind, upon the depth   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  . 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" x frequency  . Here, wavelength is the distance between two high points , frequency means the number of cycles per second Question: Where can we find this passage? Options: A: music magazine B: fashion magazine C: scientist magazine D: sports magazine

A small, happy little dog learned of this place and decided to visit. When he arrived, he jumped happily up the stairs  to the doorway  of the house. He looked through the doorway with his ears lifted high  and his tail  wagging  as fast as it could. To his great surprise, he found himself looking at 1000 other happy little dogs with their tails wagging just as fast as his. He smiled a great smile, and was answered with 1000 great smiles just as warm and friendly. As he left the house, he thought to himself, "This is a wonderful place. I will come back and visit often." In the same village, another little dog, who was not quite as happy as the first one, decided to visit the house. He slowly climbed the stairs and hung  his head low as he looked into the door. When he saw the 1000 unfriendly-looking dogs looking back at him, he _ at them and was afraid to see 1000 little dogs growling back at him. As he left, he thought to himself, "That is a terrible place. I will never go back there again." All the faces in the world are mirrors. What kind of reflections  do you see in the faces of the people you meet? Question: What does the story want to tell us? Options: A: Mirrors can tell whether  you are happy or not. B: If you show life a smile, life will smile back. C: Everyone in the world should be nice to each other. D: Happy people are more popular than unhappy ones.

Article: When a computer works on a group of programs,it can get very hot.Cooling the computer can cost a lot.So some scientists wonder what would happen if the heat from the computer could beused. Large Internet companies such as Google and Microsoft have thousands of computers.As these computers deal with information,they produce lots of heat,so they need huge cooling systems .These systems send the heat in to the air. A company in Holland thinks paying to make the computers work and then paying again to cool them are a waste of energy.So the company developed a special device-thee-Radiator. Boaz Leupe,head of the company,says that e-Radiator works as a heating system and saves money.He explains that the energy is used twice-once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers. Five homeowners in Holland are testing the heating system in their homes. "We pay for the computer using,so,in that way,homeowners get heating for free,"Boaz says.Jan Visser is one of the homeowners."If you use the computer more,the e-Radiator producers more heat,"he says,"It cannot provide enough heat if you don't use your computer often."But he is ready to try it.It's a great help for his family. The company says e-Radiators produce heat temperatures of up to 55degC.It says the system could save its users about 440 a year. Question: The best title of the passage may be"  _  ". Options: A: An Environment Problem B: A New Way to Heat Homes C: The Future Computers D: The Energy to Be Wasted.
