Directions:Read the following passage and choose the most suitable heading from this list for each paragraph.There is an extra heading.
A.Evidences of Global Warming
B.Effects on Food Production Areas
C.Influence on Inhabitable Areas
D.Ways of Reducing Greenhouse Effects
E.Difficulties in Determining the Extent of Greenhouse Effect
F.Carbon Dioxide Functions
80.________ There is much public discussion in a number of countries about ways of slowing the increase in the amount of greenhouse gases being released into the atmosphere.These include:
 Reducing the consumption of fossil fuels.Energy conservation measures can be adopted and renewable energy sources such as solar power,can be developed.
 Slowing the rate at which forests are being cleared,and introduced more reforestation programs,which would also slow the increase in carbon dioxide levels.
81._________ If global warming cannot be prevented,many countries will need to examine issues such as the planning and design of housing,particularly in low-lying areas subject to (易受.的,易遭.的) increased flooding and erosion.
82.__________ Any climatic change will affect agricultural production.Some of the world’s major food production areas could become considerably drier as a result of global warming.Other areas that are currently too dry to support agriculture may experience increased rainfall and become suitable for food production.Flood plains and river delta regions that currently grow a significant proportion of the world’s food would be permanently under water.
83.__________ Atmospheric scientists rely on satellites to collect much of their data.They have recently discovered that many of these satellites have been slipping from their orbits and so,in interpreting the measurements,scientists have assumed temperatures at a particular altitude to be lower than is actually the case.Readings have therefore been adjusted upwards.Such difficulties are just one example of the challenges facing scientists in determining the extent of global warming.There is a continuing need to research the consequences of an increased greenhouse effect.
84.__________ In examining this issue you can see that carbon dioxide,while essential for the maintenance of life on the earth,can be regarded as a pollutant in the atmosphere if its concentration becomes too high.

方向:为每个段落读下列的通道而且选择来自这一本目录的最适当的标题.有一个额外的标题.
全球的温暖 A.证据
在食物制造区域上的 B.效果
在可居住于的区域上的 C.影响力
减少温室效应的 D.方法
E.困难在决定温室效应的范围方面
F.二氧化碳功能
80.________有关减慢进入大气之内被释放的温室气体的数量增加的方法在若干的国家中有多公众的讨论.这些包括:
减少化石燃料的消费.能源保护措施能被采用,而且可重新开始的能源来源 ,像是太阳的力量,能被发展.
减慢比率在哪一森林正在被清除的,而且介绍较多的重新造林计画,这也会减慢二氧化碳水平的增加.
81._________如果全球的温暖不能够被避免,许多国家将会需要如那个计划和住屋的设计调查如此的议题,特别地在受制于的低区域中增加了泛滥和腐蚀.
82.__________任何的气候上的变化将会影响农业的制造.全球的温暖结果一些世界的主要食物制造区域可以非常地变成干燥机.现在是太干而无法支援农业的其他区域可能对于食物制造是适当的经历增加的降雨而且变成.冲积平原和现在种植世界的食物重要比例的河三角州区域会长备地是在水之下.
83.__________大气的科学家仰赖人造宇宙站收集许多的他们数据.他们最近已经发现,大部份这些人造宇宙站从他们的轨道已经滑倒,而且如此,在解释测量方面,科学家比实际上是情形已经在一种特别的高度假定温度是低的.阅读因此已经被以上调整.如此的困难只是在决定全球的温暖范围方面面对科学家的挑战一个例子.有连续的需要研究增加的温室效应的结果.
84.__________在检查你能见到的这一个议题方面如果它的集中变成太高,二氧化碳,在对于在地球上的生活维护是必要的时候,能被视为大气的一个污染物质.
