Ⅰ.阅读理解(导学号02516305)
Many people have wondered what makes the oceans rise and fall on the world's beaches twice a day.Those tides are caused 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 closer to the Moon than the Earth's center is. Because the oceans are closer, the Moon pulls harder on the water than on the Earth. This stronger pull makes the water bunch up(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 because it is“left behind”(making another high tide) as the Earth is pulled slightly towards the Moon.
When the waters bunch up on these 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 high-tide and low-tide zones. And that makes the waters on our coasts go up and down.
[语篇解读] 本文是一篇说明文，介绍了地球上海洋潮汐的原因。
1．According to the passage，there would be no tides if there were no ________ . A．Earth rotation B．gravity from the Earth C．gravity from the Moon D．Moon's gravity or Earth rotation
解析：D [细节理解题。根据第一段中的“Those tides are caused by the force of the Moon's gravity and the rotation (自转) of the Earth.”可知，潮汐是由月球的引力和地球的自转引起的。]
2．The moon's pull has a weak effect on the oceans on the opposite of the Earth， ________ .
A．so there is a low tide
B．so the water there doesn't bunch up C．but it can still make a high tide
2
D．because the Earth's gravity there is greater
解析：C [细节理解题。根据倒数第三段中的“...The Moon's pull on this water is weak.This water bunches up because it is‘left behind’(making another high tide) as the Earth is pulled slightly towards the Moon.”可知，即使是月亮的引力对地球背面的海洋有较弱的影响时，也会引起较大的潮汐。]
3．Which of the following facts can be inferred from the passage? A．Low-tide zones are near to high-tide zones. B．The oceans of the Earth are a whole body. C．High-tide zones are separated from low-tide zones. D．The Earth's surface is 4,000 miles away from the Moon.
解析：B [推理判断题。根据倒数第二段中的“When the waters bunch up on these two sides of the Earth，they draw water away from the other sides of the Earth，which creates the low tides.”可知，地球上的水会聚成一团，由此可知，地球上的海洋是一个整体。]
