问题 综合

我国在黄河三角洲打造高效生态经济区,该生态经济区包括山东东营市、滨州市全部及潍坊市、德州市、淄博市、烟台市部分地区,约占山东全省面积的六分之一。根据材料,回答下列问题。(18分)

材料一:黄河三角洲高效生态经济区示意图

材料二:黄河三角洲高效生态经济区三大产业增加值和同比增长图

(1)黄河三角洲土壤盐碱化现象较突出,分析其原因。(6分)

(2)据材料二,描述黄河三角洲经济区该时段内产业结构的变化情况。(4分)

(3)试分析黄河三角洲经济区应如何加强区内、区外的联系与合作。(8分)

答案

(1)地势低洼,海水易入侵;旱涝频繁,涝时地下水位上升,旱季蒸发旺盛,盐分聚积地表;水资源的不合理灌溉。

(2)第一产业比重下降,第二、三产业比重提高;第二、三产业同比增长速度较快。(4分)

(3)全区整体规划与布局,协调区内分工合作;完善交通基础设施建设,加强区内外联系;加强区域间技术及经济交流;突出本区产业优势,加强国内外推广,寻求合作发展。(每点2分,满分8分)

(1)从自然因素角度看,黄河三角洲地区地势低洼,海水易入侵,导致土壤盐分含量大,造成盐碱化。这里的气候旱季蒸发旺盛,地势低洼地区,旱涝频繁,涝时地下水位上升,水分蒸发,盐分聚积地表,形成土壤盐碱化。从人类活动方面看,人类农业生产中的不合理灌溉,也会导致地下水位上升,造成土壤盐碱化。

(2)读材料三图,第一产业产值增加最少,所以第一产业比重下降。第二、第三产业产值增长较多,所以第二、三产业比重提高。三类产业同比增长率都是上升趋势,但图中可以明显看出,第二、三产业同比增长速度较快。

(3)黄河三角洲经济区要加强区内、区外的联系与合作,首先要对全区进行整体规划与布局,协调区内分工合作。其次完善交通基础设施建设,加强区内外联系,加强区域间技术及经济交流。第三要突出本区产业优势,加强国内外推广,寻求合作发展。

Healthy Diet“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?

The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.

Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.

These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.

There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
