【題目】下圖為我國部分省區(qū)2005～2010年人口凈遷移率(遷入率與遷出率之差，正數(shù)表示人口凈遷入。反之為凈遷出)與人口自然增長率分布圖。讀圖，完成下列各題。

【1】下列有關(guān)我國部分省區(qū)2005～2010年人口變化狀況的敘述，正確的是

①江西省凈遷入人口數(shù)增加 ②天津人口增長率大于四川

③廣東自然增長人口數(shù)大于凈遷入人口數(shù) ④貴州人口凈減少

A．①② B．③④ C．②③ D．①④

【2】圖中人口數(shù)量的變化

A．使北京、上海、天津城市用地面積增大

B．引起江西、貴州的人口合理容量增大

C．增強(qiáng)了廣東、浙江第一產(chǎn)業(yè)的活力

D．使北京、上海人口老齡化問題更加嚴(yán)重

【答案】

【1】C

【2】A

【解析】

試題分析：

【1】讀圖，根據(jù)材料信息，江西省凈遷遷率小于0，表示遷入人口數(shù)少，是凈遷出，①錯(cuò)。天津凈遷入率和自然增長率都大于0，人口增加率數(shù)值大，而四川人口凈遷移率小于0，自然增長率大于0，人口增長率較小。所以天津的人口增長率大于四川，②對。結(jié)合圖中數(shù)值，廣東自然增長率7，人口凈遷入率約是1，自然增長人口數(shù)大于凈遷入人口數(shù)，③對。貴州人口自然增長率超過7，遠(yuǎn)大過人口凈遷入率，貴州人口增加的多，④錯(cuò)。C對。

【2】圖中北京、上海、天津人口增加率都大于0，人口增長快，城市規(guī)模擴(kuò)大，用地面積增大，A對。影響人口容量的主要因素是資源、科技水平、對外開放度和消費(fèi)水平，人口數(shù)量不是影響人口的合量容量的因素，B錯(cuò)。第一產(chǎn)業(yè)是農(nóng)業(yè)，廣東、浙江外來人口多，主要是進(jìn)入城市務(wù)工的，主要從事第二、三產(chǎn)業(yè)，C錯(cuò)。進(jìn)入北京、上海的外來人口，多為青、壯年，不會(huì)加劇老齡化，D錯(cuò)。

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（干擾） 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 (障礙) 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.
