【题目】我国人口分布的特点是( )

A.以黑河—腾冲一线为界,西北多,东南少

B.以黑河—腾冲一线为界,东南多,西北少

C.以黑河—腾冲一线为界,西部多,东部少

D.全国均匀分布

【答案】B

【解析】

根据中华人民共和国成立后,由于人民生活水平的提高和医疗卫生条件的改善,人口死亡率大幅度下降,中国人口快速增长;根据2010年全国第六次人口普查结果,中国总人口为13.7亿,约占世界人口总数的1/5,是世界上人口最多的国家,进行分析解答。

中国人口地区分布不均。一般来说,以黑龙江省的黑河云南省的腾冲线为界,东南部人口多(稠密),西北部人口少(稀疏);此线以东人口稠密,面积仅占全国总面积的43%,人口却占全国总人口的94%,此线以西人口稀疏,面积占全国总面积的57%,人口只占总人口的6%。故选:B

【题目】You may have heard of the famous saying, "East or West, home is the best.” What does the word "home" mean to you? How do you say the word in French, in Chinese, in your language? Although people usually know what the word means, it sometimes has no exact translation(翻译). It's not surprising, because the idea of home is different from country to country, and from person to person. A home is more than a roof and four walls. It's the cooking, eating, talking, playing and sleeping that go on inside. And at home you usually feel safe and relaxed.

Homes look different in different countries. They also have different things inside. For example, in cold northern Europe, there's a fire in the living room or kitchen and all the chairs face it. In the south, where the sun shines a lot and it's more important to keep the heat out, there are small windows and cool stone floors.

We asked some people about their homes.

How often do people move house in your country?

"In my country many people don't stay in one place for a very long time. They often move every ten years or so. "

-- Chery, Boston, USA

What are features (特征) of homes in your country?

"In Britain, even in town, there's always a garden. We have separate bedrooms and living rooms. But we don't often have balconies (阳台). The weather isn't warm enough! "
