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
61. The underlined word “it” in Paragraph 5 probably refers to ___________.
A.the new system                                      B. the Google company  
C.  the mobile phone                               D. the privacy minefield
62. From the passage,we know that Ian Angell believed ___________.
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
D.privacy settings could protect your personal information
63. The best title of the passage might be ___________.

For generations of pupils, learning key historical dates, places, and names off by heart has been the base of academic success. But for today’s youngsters, dull rote learning(死记硬背) is meaningless because such basic facts are only a mouse click via Google, Wikipedia and online libraries, according to writer Don Tapscott.
Tapscott, author of the best-selling book Wikinomics and a supporter of the “net generation”, suggests a better approach would be to teach children to think creatively so they could learn to understand and use the knowledge available online.
He said, “Teachers are no longer the fountain(源泉) of knowledge ; the Internet is. Kids should learn about history to understand the world and why things are the way they are. But they don’t need to know all the dates.”
Tapscott dismissed(摒弃) the idea that his approach is anti-learning. Instead, he argued that the ability to learn new things is more important than ever in a world where you have to process new information at lighting speed. And he believes that the old-fashioned model of education still common in today’s schools, involving having facts off pat, was designed for the industrial age. He said, “This might have been good for the mass production economy, but it isn’t suitable for the digital economy, or for the ‘net generation’ mind. Children are going to have to reinvent their knowledge base many times. So for them memorizing facts and figures is a waste of time.”
Tapscott added the brains of today’s youngsters work differently to their parents’, and that multi tasking with digital equipment, such as using the Internet while listening to their MP3 players, can help them to develop critical thinking skills.
Schools are increasingly introducing more independent study and activities, with pupils learning at their own pace and focusing on what interests them most.
68. What is important for the “net generation” in Tapscott’s opinion?
A. Using online knowledge creatively.
B. Memorizing facts and figures.
C. Learning to respect teachers.
D. Teaching their parents to think creatively.
69. The underlined part “having facts off pat” in Para. 4 probably means _______.
A. understanding online information
B. remembering facts clearly
C. mastering digital equipment
D. keeping mistakes in mind
70. According to Tapscott, _______.
A. learning history is of no use to kids
B. Teachers should learn more things from online libraries
C. Kids should not listen to MP3 players while using the Internet
D. to obtain new information is important for kids

第三部分:阅读理解(共20小题;每小题2分,满分40分)
阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。                          
For Senior 3 students, choosing which college to attend can be the most exciting and thrilling time in their entire school lives. This is also true for an American girl named Melanie in the film, College Road Trip, which was released in the US on March 7.
Melanie’s dad, James Porter, is the chief of police for a Chicago suburb. Incredibly security obsessed(困扰), he wants Melanie to attend nearby Northwestern University, where she’s already been accepted. But Melanie, 17, really wants to go to Georgetown in Washington, D.C., where she’s been wait-listed.
When she gets an unexpected interview, she decides to take a road trip with a few close female friends. Melanie believes it is her first step toward adulthood.
But despite the fact that this trip is “girls only”, James isn’t comfortable with the prospect of his little princess exploring the world without him. He wants to protect her.
James joins the girls and hopes he can convince her to go to Northwestern. While Melanie’s father only has the best of intentions, his presence leads to an endless series of comic encounters.
After following their faulty GPS device deep into the backwoods, James and Melanie discover her little brother and his pet pig have been hiding in the spare tire compartment(隔间). What should be a simple tire change results in the expensive car rolling down a mountain, forcing them to hike to a nearby hotel. There the pig ruins an outdoor wedding reception after eating an entire bag of coffee beans.
All these disasters add spice to their trip while along the way a father and a daughter finally get the chance to really talk to each other.
The film explores the parent-child relationship in a comic way: The discrepancy(不同) between how close James thinks he is to Melanie and how little he actually knows of her plans makes us laugh first and then think. 
All parents, whether they have college students or not, can relate to the bittersweet realization that their kids are growing up. Like what Melanie and James have done in the film, we all can find the delicate balance between staying connected and letting go.
51.According to the passage, which of the following is TRUE?
A.It’s unclear whether Melanie could be accepted by Northwestern University.
B.Northwestern University isn’t so famous as the university in Washington D.C..
C.There is no hope that Melanie will be accepted by the university in Georgetown.
D.Melanie’s father prefers her to stay not too far away from him.
52.We can infer from the passage that ________.
A.their car rolled down the mountain, ruining the wedding reception
B.a hotel was destroyed by Melanie’s brother and his pet pig
C.Melanie and her father got to understand each other better after so many encounters
D.the girls had to give up their trip because of the incidents on the way
53.What does the underlined word “released” mean?
A. set free                    B. known              C. shown               D. developed
54.The main purpose of the passage is to _______.
A.introduce the newly-released film
B.call on parents to learn to balance the relationship with their children
C.tell a story which happened between an American girl and her father
D.explore the differences in parent-child relationship between the west and the east

Every baby born a decade from now will have its genetic code (基因编码) mapped at birth, the head of the worlds’ leading genome sequencing (基因图谱) company has predicted.
A complete DNA read – out for every newborn will be technically possible and affordable in less than five years, promising a revolution in healthcare, says Jay Flatley, the chief executive of Illumina. Only social and legal problems are likely to delay the age of “genome sequences,” or genetic profiles. By 2019 it will have become routine to map infants’ genes when they are born, Dr Flatly told The Times.
This will open a new approach to medicine, by which conditions such as high blood pressure and heart disease can be predicted and prevented and drugs used more safely and effectively.
A baby’s genome can be discovered at birth by a blood test. By examining a person’s genome, it is possible to identify raised risks of developing diseases such as cancers. Those at high risk can then be screened more regularly, or given drugs or dietary advice to lower their chances of becoming ill.
Personal genomes could also be used to ensure that patients get the medicine that is most likely to work for them and least likely to have side – effects.
The development, however, will raise legal concerns about privacy and access to individuals’ genetic records.
“Bad things can be done with the genome. It could predict something about someone – and you could possibly hand the information to their employer or their insurance company.” said Dr Flatley.
“People have to recognize that this horse is out of the barn, and that your genome probably can’t be protected, because everywhere you go you leave your genome behind. Complete genetic privacy, however, is unlikely to be possible”, he added.
As the benefits become clearer, however, he believes that most people will want their genomes read and interpreted. The risk is nothing compared with the gain.
64.In the first two paragraphs, the author mainly wants to tell us about__________.
A.the significant progress in medicine      
B.the promise of a leading company
C.the information of babies’ genes    
D.the research of medical scientists
65.Which of the following is a problem caused by this approach?
A.The delaying in discovering DNA.
B.The risk of developing diseases at birth.
C.The side – effects of medicine on patients.
D.The letting out of personal genetic information.
66.What does the underlined sentence “… this horse is out of the barn” mean?
A.Genetic mapping technique has been widely used.
B.Genetic mapping technique is too horrible to control.
C.People are eager to improve genetic mapping technique.
D.people can’t stop genetic mapping technique advancing.
67.What’s Dr Flatley’s attitude towards the technology?
A.Tolerant.   B.Conservative.   C.Positive.   D.Doubtful.
