Wind is the great maker of waves. There are exceptions, such as the tidal waves, sometimes produces by earthquakes under the sea. But the waves most 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),and 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 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, for 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:

Speeding=Wavelength×Frequency

Here, wavelength is the distance between two high points (crests), frequency means the number of cycles per second.

1.What causes waves according to the passage?

A.   Earthquakes and nothing else.   B. Wind and volcanos.

C. Wind and earthquakes.          D. Wind and water.

2.Which of the following is true according to the text?

A. The water of a wave moves away across the sea.

B. The water of a wave remains almost in 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 between crest and trough.

3.The underlined word “succeeding” means__________.

A. reaching an aim    B. doing well  C. following after   D. taking place

4.If the speed of wave 1 is 100 cm/s, and its frequency 10;and the frequency of wave 2 is 300,while its speed is twice that of wave 1.Which of the following is true?

A. The wave-lengths of the two are equal.

B. The wave-length of wave 1 is 10 times longer than that of Wave 2.

C. The wave-length of wave 2 is longer than that of wave 1.

D. The wave-length of wave 1 is longer than that of wave 2.
