Ⅰ.阅读理解(导学号02516305)
Many people have wondered what makes the oceans ri and fall on the world's beaches twice a day.Tho tides are caud by the force of the Moon's gravity and the rotation(自转)of the Earth.Gravity acts on the center of any solid object. The Earth is mostly molten(熔化的) rock，but compared to the oceans，we can think of it as a solid object.
As you know，the oceans are fluid and lie on the surface of the Earth. When the Moon is overhead，the oceans are four thousand miles clor to the Moon than the Earth's center is. Becau the oceans are clor, the Moon pulls harder on the water than on the
生辰五行Earth. This stronger pull makes the water bunch up(浥轻尘集中) a little under the Moon，creating a high tide.
At the same time，the oceans on the opposite side of the Earth are four thousand miles farther from the Moon than the Earth's center is. The Moon's pull on this water is weak. This water bunches up becau it is“left behind”(making another high tide) as the Earth is pulled slightly towards the Moon.
When the waters bunch up on the two sides of the Earth，they draw water away from the other sides of the Earth，which creates the low tides.
As the Earth rotates，different parts of the land and oceans pass through the hightide and lowtide zones. And that makes the waters on our coasts go up and down.
