    科目：初中英语 来源： 题型：

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

    Now before constructing （创立）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 (浪尖）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 on the wind, on the depth of the water and many other matters.

    The water that makes up a wave does not move forward 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 first position. And it is lucky 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:

    Speed = wavelength x frequency Here, 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 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.

    (    )12. 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 the same.

    B. The wavelength of Wave 1 is a little 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 much longer than that of Wave 2.
