13．It is certainly true that computers，cell phones and digital cameras have become part of our everyday life．（71）DWe are said to be living in the Information Age，a time of new discoveries and great changes．But is it really true that we are living in the Information Age？Has our life changed that much？Many of the things we do with computers，such as typing and sending mail，are things that we also did before．（72）G
When we describe or talk about new inventions，we use words and ideas that we already know．（73）CThe words are useful，but they are not quite true．A computer does keep information in its memory，but that is clearly different from other kinds of storage．（74）FUsing familiar words makes it easier for us to understand the use of a new tool，but it may also make it more difficult for us to use the new invention in the best way．
（75）AIt is also about how we think about the world．Now that we are dev eloping new technology at such a high pace，the true challenge is to find new ways of using it．How will we use computers in the future？How will we use the Internet？The real function will only be known once we discover new ways of thinking about the technology．

A．Science is not just about electronics．
B．It's quite necessary for children to learn how to use the computer from the very start．
C．For example，when we want to explain how a computer works，we use words like"memory"，"store"and"cut and paste"．
D．Anywhere we go，we can hear the ringing of a cell phone，the tapping of a keyboard or the clicking of a mouse．
E．With time going by，more inventions connected to computers will come into being．
F．We do cut and paste，but we don't use scissors or glue．
G．Has anything really changed except the tools we use？

10．The word"conservation"has a thrifty meaning．To conserve is to save and protect，to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment．Our forefathers had no idea that human population would increase faster than the supplies of raw materials：most of them，even until very recently，had the foolish idea that the treasures were"limitless"and could"last forever"．Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature，and which means that，as in a living body，an unhealthy condition of one part will sooner or later be harmful to all the others．
Fifty years ago，nature study was not part of the school work； scientific forestry was a new idea； wood was still cheap because it could be brought in any quantity from distant woodlands； soil destruction and river floods were not national problems； nobody had yet studied long-term climatic cycles in relation to proper land use； even the word"conservation"had nothing of the meaning that it has for us today．
For the sake of ourselves and those who will come after us，we must now set about correcting the mistakes of our forefathers．Conservation should be made part of everybody's daily life．To know about the water table in ground is just as important to us as a knowledge of the basic math formulas．We need to know why all watersheds （上游集水区） need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea．We need to be taught the duty of planting trees as well as of cutting them．We need to know the importance of big，grown trees，because living space for most of man's fellow creatures on this planet is figured not only in square measure of surface but also in cubic （立方体的） volume above the earth．In a word，it should be our goal to restore as much of the original beauty of nature as we can．

63．The author's attitude towards the use of natural resources isD．
A．positive B．uninterested C．optimistic D．critical
64．According to the author，the greatest mistake of our forefathers was thatB．
A．they had no idea about scientific forestry
B．they had little or no sense of environmental protection
C．they were not aware of the importance of nature study
D．they had no idea of how to make good use of raw materials
65．To avoid repeating the mistakes of our forefathers，the author suggests thatC．
A．we plant more trees
B．natural sciences be taught to everybody
C．environmental education be directed toward everyone
D．we return to nature
66．How can you understand the underlined sentence in the last paragraph？D
A．Our living space on the earth is getting smaller and smaller．
B．Our living space should be measured in cubic volume．
C．We need to take some measures to protect space．
D．We must preserve good living conditions for both birds and animals．

17．What's black and orange and growing for the first time in decades？India's tiger population!On Monday，officials announced the results of the latest tiger count．The census（统计） totaled 1，706tigers in forests across the Asian country-about 300more than four years ago．"These numbers give us hope for the future of tigers in the world，"said Jim Leape，international director of the World Wildlife Fund．
A century ago，about 100，000tigers lived in India's forests．But by 2002，a count showed that there were only 3，600left．The number dropped to 1，411in 2007．What caused India's tiger population to shrink so dramatically？
More than anything else，experts say，development has taken a toll．People have moved into tiger territory and destroyed much of the animal's habitat．Today，tigers live on a just small part of the land they occupied 100years ago．
Illegal hunting has also contributed to the decline．Poachers（盗猎者） can demand high fees for tiger parts，which are a key ingredient in traditional Chinese medicine．The parts from one tiger can sell for tens of thousands of dollars．
India's news is a step in the right direction．But while the number of tigers has increased there in the last four years，the animals'habitat has shrunk．Roads and construction projects have blocked off many tiger corridors-routes used by the big cats to go from one forest to another．"Securing these corridors should be taken up as a priority，"says Rajesh Gopal，of the National Tiger Conservation Authority．
Last November，leaders from the 13countries that are home to wild tigers met in St．Petersburg，Russia，to develop a plan to help the endangered cats．They set a goal to double the world's tiger population by the year 2022．Will we reach that goal？With India's tiger population on the rise and conservationists around the world focused on helping the big cats，it seems it just might happen．

63．The underlined word"shrink"in Paragraph 2most probably meansB．
A．develop B．reduce C．disappear D．remove
64．Which is one of the reasons why India's tiger population declines？A
A．Some living areas of India's tigers are destroyed by humans．

11．London：It's well known that Charles Darwin's famous theory of evolution （进化） annoyed many people because it was against the Biblical view of creation．But few know that it also created problems for Darwin at home with his deeply religious wife，Emma．
"Darwin held back the publication of On the Origin of Species to avoid offending （触怒） his wife，"says Ruth Padel，the naturalist's great-great-granddaughter．"Emma told him that he seemed to be putting God further and further off"，Padel says in her north London home．"But they talked it through，and Emma once said，‘Don't change any of your ideas for fear of hurting me．'"
As the world celebrates the 200th birthday of the man who changed scientific thought forever and the 150th anniversary of his book today，even his opponents admitted he was a giant figure．
Though opposition to his theory continues，it is the elegant explanation of how species evolutes through natural selection that makes his 200th birthday such a major event．
More than 300celebrations have been planned in Britain alone，where Darwin's face graces （使增光）the 10-pound bill along with that of Queen Elizabeth II．
Shrewsbury，the central England town where Darwin was born and raised，is holding a month-long festival for its most famous son．Down House，his former home near London，will hold a permanent exhibition recreating some of his most famous experiments．
