Do you want to live another 100 years or more? Some experts say that scientific advances will
one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
67. By saying “ we are knocking at the door immortality”, Michael Zey means_____.
A. they believe that there is no limit of living
B. they are sure to find the truth about long living
C. they have got some ideas about living forever
D. they are able to make people live past the present life span
68. Donald Louria’s attitude toward long living is that_____.
A. people can live from 120 to 180
B. it is still doubtful how long humans can live
C. the human body is designed to last about 120 years
D. it is possible for humans to live longer in the future
69. The underlined “ it” (Para. 4) refers to_____.
A. a great push
B. the idea of living beyond the present life span
C. the idea of living from 200 to 300
D. the conservative estimate
70. What would be the best title for this text?

B. Science, technology and long living
C. No limit for human life
D. Healthy lifestyle and long living

举一反三
Americans are thinking about national education standards recently developed by teachers and other education experts. The National Governors Association (NGA) and the Council of Chief State School Officers (CCSSO) led the effort.
The United States, unlike other nations, has never had the same school standards across the country. What is the reason? Education is not discussed in the Constitution. That document limits the responsibilities of the federal government. Other responsibilities, like education, fall to the individual states.
Local control of education probably was a good idea two hundred years ago. People stayed in the same place and schools knew what students needed to learn. But today, people move to different cities. And some people work at jobs that did not exist even twenty years ago.
Many American educators say that getting a good education should not depend on where you live. They say that some states have lowered their standards in order to increase student scores on tests required by the No Child Left Behind Act.
Kara Schlosser is communications director for the Council of Chief State School Officers. She says the new standards clearly state what a student should be able to do to be successful in college and work.
Forty-eight states have already shown approval for the standards. Two states reject the idea. Critics(批评家) say that working toward the same standards in every state will not guarantee(保证) excellence for all. Some educators in Massachusetts say adopting the proposal will hurt their students because the state standards are even higher. Others say the change will be too costly, requiring new textbooks and different kinds of training for teachers. Still others fear federal interference or control.
Supporters say the standards are goals and do not tell states or teachers how to teach. They also say the federal government is not forcing acceptance. However, approving the standards will help states qualify(合格) for some federal grant money.
60.What would be the best title for the passage?
A.Local Control of Education Standards out of Date
B.American National Education Standards under Consideration
C.Education Standards in Each State – Good or Bad
D.Acceptance of the New Standards in the United States
61.Why is local control of education no longer a good idea today?
A.Because local standards are limited.
B.Because it is required by the federal government.
C.Because people today moves among states more often than before.
D.Because America has never has the same school standards thought the country.
62.Some people are against the national education standards because__________.
A.the standards are higher than those of each state
B.the are nor yet prepared for the new standards
C.the standards may prevent some students gaining excellence
D.they don’t want the federal government to train their teachers
63.If a state agrees to accept the motional standards, it will probably get__________.
A.more students B.advice on how to improve teaching
C.better textbooks D.money from the federal government
Dear Customers,
I love slipping into a comfortable chair for a long read —as I relax into the chair,I also relax
into the author’s words,stories,and ideas.The physical book is so elegant that it disappears into
the background,and what remains is the author’s world.
Today,we at Amazon are excited to announce Mindle,a wireless,portable reading device with instant access to more than 90,000 books,magazines,and newspapers.
We’ve been working on Mindle for more than three years.Our top design objective was for
Mindle to disappear in your hands —to get out of the way —so you can enjoy your reading.We
also wanted to go beyond the physical book.Mindle is wireless,so whether you’re lying in bed or riding a train,you can think of a book,and have it in less than 60 seconds.No computer is needed—you do your reading directly from the device.
We chose the same wireless technology used in advanced mobile phones.But unlike mobile
phones,there are no monthly wireless bills,no service or data plans,and no yearly contracts.There
is no software to install.We want you to get lost in your reading and not in the technology.
Mindle uses a new kind of display called electronic paper.Sharp and natural with no strong
light,reading on Mindle is nothing like reading from a computer screen.Mindle weighs only 10.3
ounces —less than a paperback —but can carry two hundred books.
Enjoy learning about Mindle and many thanks!
60.This passage most probably is a(n)_________.
A.advertisementB.news story C.lab report D.letter of thanks
61.From the passage we learn that Mindle is a device(设备)which.
A.has neither wires nor weightB.is operated by a computer
C.disappears while you read D.can find a book within one minute
62.With the device,the reader is able to .
A.enjoy reading when driving a car B.improve reading skills
C.gain access to free software D.get rid of heavy books made of paper
63.Different from mobile phones,Mindle_________.
A.has a much more friendly screen B.can work in the absence of electricity
C.doesn’t involve regular fees D.is wireless and can be used anywhere
Damage to Ozone layer Gets Worse
In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer. The warning is: The sun’s summertime rays are more dangerous than once thought.
A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone (臭氧层) in the atmosphere, which protects humans from harmful levels of ultraviolet radiation(紫外线辐射), will be thinner over the United States this summer. The thinner layer allows more ultraviolet rays from the sun to reach Earth. The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
Scientists first became concerned about the ozone layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter. The hole was caused by chemicals used in refrigerators and air conditioners. When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.
Concern about the protective ozone layer rose more recently when data(数据) from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica. Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.
Although many countries have already begun stopping the use of ozone destroying chemicals, the new findings are expected to advance the timetable for a total ban(禁止) of the chemicals.
59. The scientists have observed the ozone layer_____.
A. since 1980 B. since last winter
C. for about 20 years D. for about one year
60. The ozone layer in the atmosphere can _____.
A. do a lot of good to human beings in many ways.
B. protect humans from diseases caused by bad weather.
C. do a lot of harm to human beings in the summer-time.
D. protect humans from harmful levels of ultraviolet radiation.
61. Scientists first found that there was a hole in the ozone layer_____.
A. above Arctic during the winter in the mid-1980s
B. above Antarctica during the winter in the mid-1980s
C. over somewhere in the north of the equator in 1980
D. over the U.S.A in the summertime in the mid-1980s
62. The damage to the ozone layer was caused by_____.
A. the changeable weather
B. ozone-destroying chemicals
C. chemicals from refrigerators
D. chemicals from air conditioners

Millions of people will be able to track each and every move by friends and family through their mobile phones,thanks to a new feature launched by Google yesterday.
The new system named “Latitude” uses a map to show exactly where a loved one is at any time, sometimes discovering their location to a few meters.Worried parents will be able to check up on where their children have got to after school, friends can meet for a quick drink if they see they are nearby and wives will be able to see if their husbands really are working late at the office.
The feature was made available immediately on millions of mobile phones that can access the web,such as the Black Berry.Within weeks Google hopes to launch a new one that will also work on computers as well.
“Once you"ve shared your location,you can hide it from all of your friends at once,or you can turn off Google Latitude completely at any time.” said a Google spokesman.“You can adjust your privacy settings in Latitude so that you share as much or as little about your location as you want,with whom you want.”
Google said that the company had tested the product with thousands of people to make sure that it was safe for the customers,but experts were not so sure.Simon Davies,director of Privacy International,said Latitude would open up a “privacy minefield(危险地带)”.
“It"s about the little white lies.You might be avoiding going to work, and now your boss might be able to see that you"re at Twickenham instead of at home.”said Ian Angell, an information expert at the London School of Economics.“You"ve already got mobile phone technology where husbands and wives track each other in secret.Now Google is so widely used that it will only worsen the situation.”
60. According to Google,the new system “Latitude” can ___________.
A.prove that the partner has told a lie about working late
B.tell the parents the locations of their children after school
C.provide the friends with the most suitable pub for a drink
D.help people find what their loved ones are doing at any time

A.Latitude keeps husbands and wives in good relationship
B.Google tricked all its customers to make more money
C.with Latitude more privacy problems would come up
