中考英語內(nèi)容包含聽力、閱讀例句、完型填空、寫作等多個(gè)部分，其中，中考英語閱讀理解所占的比重是很大的。想要在中考英語中拔得頭籌，千萬不能忽視閱讀理解部分的練習(xí)。

The Earth is the third planet from the Sun and the only planet known to have life on it. It is the fifth largest planet in the solar system and has a diameter of about 12,756 kilometers. The Earth's surface is made up of land and water, with about 29.2% of the surface land and the rest covered by water.

The Earth's atmosphere is essential for life to exist. It provides us with the air we breathe and protects us from harmful radiation from the Sun. The atmosphere also helps to regulate the Earth's temperature, making it suitable for life.

The Earth rotates on its axis once every 24 hours, causing day and night. It also revolves around the Sun, taking approximately 365.25 days to complete one orbit. This movement of the Earth results in the change of seasons.

The Earth's resources are finite, and it is important for us to conserve and protect them. We must also take care of the Earth's environment to ensure a sustainable future for all living beings.

2.B

文章第一段提到“with about 29.2% of the surface land and the rest covered by water”，地球表面大約29.2%是陸地，其余部分被水覆蓋。因此，水覆蓋的部分是100% - 29.2% = 70.8%，所以答案是B。

3.C

文章第二段提到“The atmosphere also helps to regulate the Earth's temperature, making it suitable for life.”，大方層能夠幫助調(diào)節(jié)地球的溫度，使其合適生命存在。因此，大方層有哪些用途是調(diào)節(jié)地球溫度，所以答案是C。

4.C

文章第三段提到“It also revolves around the Sun, taking approximately 365.25 days to complete one orbit.”，地球圍繞太陽公轉(zhuǎn)，大約需要365.25天完成一次公轉(zhuǎn)。因此，答案是C。
