阅读理解 The water level of oceans rises and falls alternately twice a day. This movement of water is called the tide. Tides are caused by the pull of the sun and the moon on the earth's surface; since the moon is closer, it affects the tides more than the sun. When the moon is directly overhead, it actually pulls on the water that is below it. This causes the water level to rise because the water is pulled away from the earth. As the moon disappears over the horizon (地平线), the pull lessens and the water level settles back towards the ocean bottom. When the water reaches its highest level, we have high tide. And when the water comes to its lowest level, we have low tide. From its lowest point, the water rises gradually for about six hours until it reaches high tide. Then it begins to fall continuously for about six hours until it reaches low tide. Then the cycle (循环) begins again. (1) Which of the following may be the best title for the passage? [ ] A．The Moon and Oceans B．The Moon and the Tide C．Water Levels D．The Pull of the Moon and the Sun (2) The pull of the moon on the earth's surface is stronger than that of the sun because ________. [ ] A．the moon is directly over the earth B．the moon pulls the water away from the earth C．the moon is closer to the earth D．the moon moves around the earth (3) Water level reaches its low point when ________. [ ] A．the moon is hidden by cloudsB．the moon's effect is indirect C．the moon moves far awayD．the sun is overhead (4) High tide occurs ________. [ ] A．every 12 hoursB．every 6 hours C．every 24 hoursD．every 18 hours (5) According to the passage, which of the following is true? [ ] A．Weather sometimes affects tides. B．The force directly affecting the earth's surface comes from the the moon only. C．The effect of the sun on the ocean water can be neglected. D．Tides are the result of the pull of the moon and the sun.

The water level of oceans rises and falls alternately twice a day. This movement of water is called the tide. Tides are caused by the pull of the sun and the moon on the earth's surface; since the moon is closer, it affects the tides more than the sun. When the moon is directly overhead, it actually pulls on the water that is below it. This causes the water level to rise because the water is pulled away from the earth. As the moon disappears over the horizon (地平线), the pull lessens and the water level settles back towards the ocean bottom.
When the water reaches its highest level, we have high tide. And when the water comes to its lowest level, we have low tide. From its lowest point, the water rises gradually for about six hours until it reaches high tide. Then it begins to fall continuously for about six hours until it reaches low tide. Then the cycle (循环) begins again.
(1) Which of the following may be the best title for the passage?
[ ]
A．The Moon and Oceans
B．The Moon and the Tide
C．Water Levels
D．The Pull of the Moon and the Sun
(2) The pull of the moon on the earth's surface is stronger than that of the sun because ________.
[ ]
A．the moon is directly over the earth
B．the moon pulls the water away from the earth
C．the moon is closer to the earth
D．the moon moves around the earth
(3) Water level reaches its low point when ________.
[ ]
(4) High tide occurs ________.
[ ]
(5) According to the passage, which of the following is true?
[ ]
A．Weather sometimes affects tides.
B．The force directly affecting the earth's surface comes from the the moon only.
C．The effect of the sun on the ocean water can be neglected.
D．Tides are the result of the pull of the moon and the sun.
题目解答
答案
解析
考查要点：
- 标题归纳能力：需根据文章核心内容选择最贴切的标题。
- 细节理解能力：明确太阳与月球对潮汐的影响差异。
- 逻辑推理能力：结合时间描述推断潮汐周期。
- 信息筛选能力：排除干扰项，锁定正确陈述。
解题核心思路：
- 抓住文章主旨：潮汐由月球和太阳的引力引起，月球作用更大。
- 关注关键细节：月球距离地球更近、潮汐变化周期、高低潮形成条件。
- 排除法应用：结合选项与原文对比，排除与描述矛盾的选项。
第（1）题
关键点：文章主要解释潮汐的成因，强调月球的作用。
- 选项B（The Moon and the Tide）直接点明文章核心，涵盖月球与潮汐的关系。
- 其他选项（如A、D）范围过宽或未突出潮汐，C（Water Levels）未体现成因。
第（2）题
关键点：月球对潮汐的影响更大，因其距离地球更近。
- 选项C（the moon is closer to the earth）与原文“月球更近”一致。
- A、B、D均未直接说明引力强弱的根本原因。
第（3）题
关键点：低潮发生在月球引力减弱时。
- 选项C（the moon moves far away）对应“月球消失在地平线后，水位回落”。
- 其他选项（如A、B）与月球位置无关，D（太阳主导）错误。
第（4）题
关键点：高低潮交替周期为12小时。
- 选项A（every 12 hours）符合“每6小时涨落一次，总周期12小时”。
- B、C、D均与时间描述矛盾。
第（5）题
关键点：太阳和月球共同作用形成潮汐。
- 选项D（tides are the result of the pull of the moon and the sun）与原文一致。
- A（天气影响）未提及，B（仅月球作用）错误，C（忽略太阳作用）片面。
