【題目】下圖所示為沙特阿拉伯沙漠中的灌溉農業(yè)景觀圖,讀圖完成下列問題。

【1】圖示地區(qū)大力發(fā)展種植業(yè)易造成（ ）

A.地下水枯竭 B.土地荒漠化

C.水土流失 D.植被破壞

【2】為保障糧食供應的穩(wěn)定，圖示國家應（ ）

A.擴大本國耕地面積

B.在國外適宜地區(qū)投資農業(yè)生產(chǎn)獲得糧食

C.提高農業(yè)機械化水平

D.修建水庫等水利設施，加強水利建設

【答案】

【1】A

【2】B

【解析】

試題分析：

【1】沙特阿拉伯在沙漠地區(qū)發(fā)展灌溉農業(yè)，主要依賴于靠抽取地下水作為灌溉水源，所以在沙漠地區(qū)大規(guī)模發(fā)展灌溉農業(yè)最易造成地下水枯竭選項A正確；該地本來就是沙漠地區(qū)，地表幾乎沒有植被，談不上破壞植被和土地荒漠化現(xiàn)象；更談不上水土流失現(xiàn)象。選項B、C、D錯誤。

【2】圖示國家沙漠廣布，灌溉水源短缺，在國內不適于農業(yè)的大規(guī)模發(fā)展，為保障糧食供應的穩(wěn)定，應該尋求國際合作，在國外適宜地區(qū)投資農業(yè)生產(chǎn)以此獲得糧食，乃是長久之計。選項B正確。

【題目】【2015·北京卷】D

Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes. An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (調查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.

However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.

In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents - today’s grandparents - would have called their children more often if the means and cost of doing so had not been a barrier.

Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.

Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyondthe role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

【1】The surveys inform us of ______.

A. the development of technology

B. the changes of adult children’s behavior

C. the parents’ over-protection of their college children

D. the means and expenses of students’ communication

【2】The writer believes that ______.

A. parents today are more protective than those in the past

B. the disadvantages of new technology outweigh itsadvantages

C. technology explains greater parental involvement with theirchildren

D. parents’ changed attitudes lead to college children’s delayedindependence

【3】What is the best title for the passage?

A. Technology or Attitude

B. Dependence or Independence

C. Family Influence or Social Changes

D. College Management or Communication Advancement

【4】Which of the following shows the development of ideas in this passage?
