题目内容

【题目】资源型城市随资源利用而兴起,随资源枯竭而衰败。因此,资源枯竭型城市的转型问题已成为可持续发展的迫切要求。据此回答第下列小题。

【1】下列关于资源枯竭型城市存在问题的叙述,正确的是

①产业结构单一 ②环境污染严重 ③科学技术发展快 ④矿产可开采量减少

A①②③ B②③④ C①③④ D①②④

【2】资源枯竭型城市寻找新出路,下列举措不正确的是

A优化产业结构,加快产业升级

B整体搬迁

C大力发展耗能低、污染小、效益高的产业

D在废矿区发展高效生态农业

【答案】

【1】D

【2】B

【解析】

试题分析:

【1】资源枯竭型城市当初的发展,是建立在当地资源开发的基础上发展的,随着时间的推移,资源逐渐枯竭,原有的资源优势丧失。资源枯竭型城市的产业结构与老工业区类似,以重化工业为主,结构单一,环境污染严重。由于资源枯竭型城市面临经济转型,城市缺乏活力,没有足够的吸引力,科学技术发展速度不会过快。故选D。

【2】优化产业结构,加快产业升级,可以减少对资源的依赖程度;大力发展投资少、消耗低、污染小、效益高的产业,使产业结构多样化,加快产业转型;在废矿区发展高效生态农业而整体搬迁,会影响经济发展,也不现实故不正确的选B。

【题目】A food chain is a simple way of explaining how each living thing gets its food.For examplea simple African food chain might consist of three parts(1)trees and bushes(2)giraffes; and(3)lions.Each link in a food chain is food for the next link.Food chains always start with plants and end with animals.

Plants are at the bottom of the food chain.Scientists call them producersbecause they use light energy from the sun to produce food from carbon dioxide and water through photosynthesis(光合作用)Animalsunlike plantscan't produce their own food.Insteadthey must eat plants or other animals.This is why scientists call them consumers.

Consumer animals fall into three categories.Herbivores eat only plants.Carnivores eat only other animals.Omnivores eat both plants and animals.In addition to producers and consumersthere are also decomposers.These organismssuch as bacteria and fungifeed on decaying matter.They help the food chain by speeding up the decaying process that releases minerals back into the soil to be absorbed by plants as nutrients.

Most food chains have only four or five links in them.As you go up a food chainthe amount of energy at each level diminishesbecause some of the energy is lost in the form of waste or is used up by the organism at that level.That is why it takes many plantsfor exampleto feed a few giraffes who in turn feed one lion.

Most animals are part of many different food chainsbecause they must eat more than one type of food to satisfy their energy needs.All of these interconnected food chains form a more complex structure called a food web.Humansfor exampleare at the center of a very complex food webbecause we tend to eat many different types of plants and animals.
