The lights will stay off for one hour for an event called Earth Hour.The observance(17)is organized by a conservation group,the World Wide Fund for Nature,also known as the World Wild Fund.For the fourth year,people are being urged to (18)turn off their lights for one hour to call attention to the issue of climate change.The group says climate change is one of the (19)greatest threatsfacing wildlife and nature.
The first Earth Hour was held in 2007in Sydney,Australia.Organizers said more than 2,000businesses and two million people took part.(20)Since then,Earth Hour has grown into an international event.People in more than 4,000cities in 88countries took part last year.

分析 文章讲述了地球一小时活动.为了引起人们对地球气候改变的重视,地球保护组织和世界生物基金会组织了关灯一小时的活动.现在已经成为国际上的一件大事,很多城市和国家都参与进来.

解答 答案:16.go dark;考查句意理解.前面说所有的灯都关闭了,当然会一片漆黑.    
17.is organized;考查句意理解.后文出现了organizers,说明是组织这项活动;organize与主语observance构成动宾关系,要用被动语态. 
18.turn off;考查语境理解.文章讲述的是这项活动是通过关灯来引起人们对地球气候变化的重视. 
19.greatest threats;考查语境推断.文章讲述了野生动植物和大自然面临威胁,而气候变化是其中最大的威胁之一.  
20.Since then;考查语法知识和句意理解.句中Earth Hour has grown into an international event用的是现在完成时态,表示结果;要用since then作时间状语,表示从那时起.

点评 语法填空题是考查学生的语言运用能力.解题时,要在理解文章的基础上,灵活运用语法知识,如词性,时态,名词单复数,连接词,代词,冠词等判断空白处应填写的内容.答完后,还要通读全文,核对所填单词形式是否正确,是否符合语境.

3.A rapidly advancing contemporary science that is highly dependent on new tools is Earth system science.Earth system science involves observation and measurements on the Earth at all scales from the largest to the smallest.The huge amounts of data that are gathered come from many different locations and require special techniques for handling data.Important new tools that facilitate Earth system science include satellite remote sensing,small deep-sea submarines,and geographic information systems.
More than any other way of gathering evidence,satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts.
Earth system science was born from the realization of that interdependence.Satellite remote sensing makes possible observations at large scales,and in many cases,measurements of factors that could not otherwise be measured.For example,the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing,as are changes in deserts,forests,and farmlands around the world.Such measurements can be used in many areas of specialization besides Earth system science.Archaeology,for example,has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert.
New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system.Small deep-sea submarines allow scientists to travel to the depths of the ocean.There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat,sasses,and mineral-rich water.
Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system.Computer-based software programs known as geographic information systems,or GIS,allow a large number of data points to be stored along with their locations.These can be used to produce maps and to compare different sets of information gathered at different times.For example,satellite remote sensing images of a forest can be converted to represent stages in the forest's growth.Two such images,made at different times can be overlaid and compared,and the changes that have taken place can be represented in a new image.

1.The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive"attachment"period from birth to three may scar a child's personality and lead to emotional problems in later life.Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it causes,and many people do believe this.But there are also arguments against such a strong conclusion.
Firstly,anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies.For example,in some tribal societies,such as the Ngoni,the father and mother of a child did not bring up their infant alone-far from it.Secondly,common sense tells us that day care would not be so widespread today if parents,care-takers found children had problems with it.Statistical studies of this kind have not yet been carried out,and even if they were,the results would be certain to be complicated and controversial.
Thirdly,in the last decade,there have been a number of careful American studies of children in day care,and they have uniformly reported that day care had a neutral or slightly positive effect on children's development.But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.
But Bowlby's analysis raises the possibility that early day care has delayed effects.The possibility that such care might lead to,say,more mental illness or crime 15 or 20 years later can only be explored by the use of statistics.Whatever the long-term effects,parents sometimes find the immediate effects difficult to deal with.Children under three are likely to protest at leaving their parents and show unhappiness.At the age of three or three and a half almost all children find the transition to nursery easy,and this is undoubtedly why more and more parents make use of child care at this time.The matter,then,is far from clear-cut,though experience and available evidence indicate that early care is reasonable for infants.
74.The passage primarily argues whetherC.
A.day care should be widely spread
B.the family relationship is different in traditional societies
C.children under three should be sent to nursery schools
D.children over three will stop crying when leaving parents
75.The underlined word"it"in the first paragraph most probably meansA.
A.children's being subjected to day care           
B.the conclusion from Bowlby's work
C.the sensitive"attachment"period                  
D.a child's personality
76.Which of the following statements is NOT against Bowlby's theory?B
A.Day care is safe,otherwise there wouldn't be so many nursery schools.
B.Parents find the immediate effects of early day care difficult to deal with.
C.Many studies show that day care has a positive effect on children's development.
D.Separation from parent for very young children is common in some traditional societies.
77.The writer's attitude towards early day care is thatD.
A.children under three should stay with their parents
B.the effects of early day care on children are exaggerated
C.early day care has positive effects on children's development
D.the issue is controversial and its settlement calls for the use of statistics.
