Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard. They were all started before the American Revolution made the 13 colonies into states.In the early years, these schools were much alike. Only young men attended colleges. All the strdents studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and no kind of school could teach everything that was know about the world. When the students graduated, most of them became ministers or teachers.In 1782, Harvard started a medieal school for young men who wanted to become doctors. Later lawyers could receive their training in Harvards law school. In 1825, Harvard began teaching modern languages, such as French and Germany, as well as Latin and Greek. Soon it began teaching American history.As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.Apecial coooeges for women were started. New state universities began to teach such subjects as farming, engineering and business. Today, there are many different kinds of colleges and universities. Most of them are divided into smaller schools that deal with special fields of learning.

There are exceptions, such as the tidal(潮汐的)waves sometimes produced by earthquakes under the sea. But the waves mast of us know are produced by winds-blowing over the sea.Now before constructing an imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough(low point) to crest (high point). It has length, the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests 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 fortunate that this is so. Far if the huge masses of water that make up a wave actually 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 frequencyHere, wavelength is the distance between two high points (crests), frequency means the number of cycles per second.10. What causes waves?A. Earthquakes and nothing else.B. Only wind.C. Wind causes most waves.D. Wind causes some waves.11. Which of the following is tr
