    【题目】七选五

    根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    Different Cultures

    The cultures of the East and the West really distinguish each other a lot. 【1】 The origin of the eastern cultures is mainly from two countries: China and India. Both of the two cultures are developed by rivers-the Yellow River in China and the Hindu River in India. 【2】

    When the two mother rivers gave birth to the Eastern culture, another famous culture was brought up on the Mesopotamian Plain-the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Greece and Ancient Rome. 【3】 Like the Chinese culture, the European culture also crossed waters. When the British settled down in America, their culture went with them over, the Atlantic Ocean. So the American culture doesn't distinguish from the European culture a lot。

    【4】 Take the language system for example. In the East, most languages belong to the pictographic language while the Western languages are mostly based on the Latin system. Other causes like human race difference counts as well. But what's more. due to the far distance and the steep areas between the East and West, the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no-interference（干扰） from the other.

    The differences are everywhere. 【5】 But different cultures make the world of 21st century more colorful. The cultural gap should not be the obstacle (障碍) to the civilization of human being. It ought to be the motivation of our going farther.

    A. Let us work together to keep a variety of culture.

    B. One important thing is to learn about other cultures.

    C. And these two are well-known as the base of the European culture.

    D. At the same time, some other differences add to the cultural differences.

    E. This is because the culture systems are two separate systems on the whole.

    F. They helped the two cultures develop for centuries and form their own styles.

    G. They are obvious and affect people's ways of thinking and their views of the world.
