急須高一英語閱讀理解題（附翻譯）

【專家解說】：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 an imaginary life history of a typical wave, we need to know certainphysical things about it. A wave has height, from trough ( low point) to crest ( high Point) . It has lengh-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. 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 × frequencyHere, wavelength is the distance between two high points (crests) , frequency means the number of cycles per second 18. What causes waves?A. Earthquakes and nothing else. B. only wind.C. Wind causes most waves. D. Wind causes some waves.19. 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.20.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.答案DACBD翻譯風能是波浪大制造商。但也有例外，如潮水（潮汐的），有時是根據(jù)地震產生的海浪。不過，波大多數(shù)的人都被吹的海面風造成的。 現(xiàn)在才興建一個典型的波想象生命的歷史，我們需要知道一些 對此物理事物。 A波從低點（高點）波峰（高點的高度）。它有國境線，從這個波峰距離下面的浪潮。在波期間的意思是，它成功的徽章需要通過一個固定點。這些東西沒有保持不變-所有取決于風后水的深度和許多其他事項。 水是構成了波浪不事先與它隔海相望。每一滴水轉身在與波通過小圓圈，但回報率非常接近到原來的位置。它是幸運的，這是如此。因為如果水的龐大群眾，使一個浪潮，實際上在海上移動，航行是不可能的。 如果我們想找到一個波的速度，我們可以采用下列方式： 速度=波長×頻率 在這里，波長是兩個（波峰）高點的距離，頻率指每周期數(shù)第二 18。波是什么原因？ 答：地震，別無其他。 b.只有風。 C.風導致大部分波。 D.風導致一些波浪。 19。下列哪項是正確根據(jù)的通過？ 答：波浪的水遷離隔海相望。 B的波水仍然幾乎在同一個地方。 長波浪的水去同波傳遞。 D.對波浪的長度是指從波浪的頂部距離底部。 20.The波1速度100厘米/秒，頻率10。在第2波的頻率是300，而其速度的兩倍波1。下列哪項是正確的？ 阿。兩者的波長是相等的。 B的波1波長的10倍以上的波2的。 丙級第2波的波長長于波1的。 D.對波1波長長于波2的。
