(1)写出图中数字表示的地理事物名称:

山脉:①___________、③_____________;河流:④____________。

(2)黄土高原的地表特征是_______________________________________________。

(4)治理黄土高原水土流失的主要生物措施是_______________________________。

答案

(1)太行山   秦岭   黄河    

(2)千沟万壑、支离破碎

(3)夏季多暴雨      土质疏松    

(4)植树种草

题目分析:

(1)读图可知,黄土高原位于长城以南,③秦岭以北,祁连山乌鞘岭以东,①太行山以西,是世界上黄土分布面积最广的区域。

(2)由于土质疏松,植被稀少,在夏季暴雨的冲刷下,水土流失严重,形成了黄土高原千沟万壑、支离破碎的地表形态。

(3)严重的水土流失带来的后果水土流失可使大量肥沃的表层土壤丧失,造成土壤肥力下降,耕地面积大为减少,同时大量泥沙注入黄河,淤塞河道,给下游地区的防洪带来严峻的考验,历史上黄河下游曾多次决口泛滥,给华北地区的人民带来了深重灾难,黄土高原生态环境脆弱。

(4)治理的措施是:植树造林,修建梯田,退耕还林还牧、修挡土坝等。

Please help! I live in Germany with my wife and three kids. My parents live in the UK. I want my kids to have as much contact with their grandparents as possible. The kids all use e-mail, Skype and SMS but my parents won’t. I’ve bought them a laptop, paid for broadband, given them both mobile phones and a digital camera, but they won’t use them. My parents say they hate computers and new technology. What can I do with these “technophobes”?

Daniel, Buremburg, Germany

Actually, the original technophobes were the Luddites, a group of cloth workers in 19th century Britain during the Industrial Revolution. The Luddite cloth workers, who traditionally made cloth by hand, were worried that machines were going to take away their jobs and way of life. These machines could make cloth much faster and cheaper than humans. In 1811 and 1812 the Luddites destroyed the machines that they hated so much, but the British government supported the factory owners. Many Luddites were arrested. Charlotte Bronte’s novel Shirley will tell your parents all about it.

Laura, Valencia, Spain

Laura makes some interesting points, I think. Technophobes has been a common theme in science fiction. Frankenstein, one of the first science fiction, is a warning of what could happen if humans began to experiment with human life.

One thing you could try is to find hardware that is designed for older people to use. An example is the mobiles made by the US company, Jitterbug. Instead of icons and menus the Jitterbug phones ask users simple “yes/no” questions and have larger keypads. The company realized that there are potentially 100 million older users in the US alone.
