6．Leading scientists have joined the growing chorus of concern （worry） about governments and companies rushing into producing biofuels （生物燃料） as a solution for global warming，saying that it could be harmful if they do not consider the long-term influence of what they are doing carefully．
It is necessary to build standards for the supply system of any green fuel project in order to make sure that there aren't any side effects  on the environment and social structures．The report produced by the scientists expresses concern that many companies may not be fully aware of the possible disadvantages．
Production of crops （农作物），such as corn and soya beans，has increased greatly in the last few years as another eco-friendly choice to natural fuels，but environmental and human rights movement leaders are worried that this will lead to destruction （破坏） of rain forests．Food prices could also go up as there is increasing competition for crops as both food and sources of fuels．Last week，the UN warned that biofuels could have dangerous side effects and said that steps need to be taken to make sure that land chosen to grow biofuels does not damage the environment or social structures．There is already great concern about palm oil （棕榈油），which is used in many foods in addition to being an important biofuel，as rain forests are being cleared in some countries and people driven from their homes to plant more palms．
The report suggests that biofuels are not a solution for climate change but they can play their part as long as governments and companies manage the social and environment influence thoroughly．There should also be greater measures （措施） taken to increase the effectiveness and to reduce needs．

58．The underlined phrase"side effects"probably meansB．
A．improving conditions
B．unwanted results
C．increasing influences
D．unchanged advantages
59．The third paragraph is mainly aboutD．
A．the danger of rain forests
B．the warning given by the UN
C．the green biofuels liked by people
D．the possible disadvantages of biofuels
60．What can we infer from the passage？A
A．The development of biofuels will probably influence people's daily life．
B．Greater measures should be taken to reduce the amount of biofuels．
C．Almost all the companies are worried about the future of biofuels．
D．Rain forests are being cleared to grow more palms as biofuels．

5．Imagine you're at a party full of strangers．You're nervous．Who are these people？How do you start a conversation？Luckily，you've got a thing that sends out energy at small chips（芯片） in everyone's name tag（标签）．The chips send back name，job，hobbies-whatever．Making new friends becomes simple．
This hasn't quite happened in real life．But the world is already experiencing a new age of using RFID technology．
An RFID tag with a small chip can be fixed in a product，under your pet's skin（皮肤），even under your own skin．Some RFID tags have no energy source because they do not need it．The energy comes from a scanning device（扫描装置），which sends out energy and starts up the tag immediately．
Such a tag carries information to that object，and the information can be renewed．Already，RFID technology is used for recognizing（识别） each car or truck on the road and it might appear in your passport．Doctors may put a small chip under the skin to get a patient's medical records．At a nightclub in Paris or in New York the same chip might get you to pay for the bill with the wave of an arm．
Take a step back：10or 12years ago，you would have heard about the coming age of computing．One example always seemed to surface：Your refrigerator would know when you needed to buy more milk．The idea was that computer chips could be put everywhere and send information in a smart network that would make life simpler．
RFID tags are a small part of this situation．"The world is going to be a connected set of personal small devices．"predicts Dr．J．Reich．But some people are nervous about the possibilities of such technology．It goes too far tracking（跟踪）school kids through RFID tags，they say．
When Marconi invented radio，he thought it would be used for ship-to-shore communication，not for pop music．Who knows how RFID and other technologies will be used in the future．Here's a wild guess：Not for buying milk．

58．We know from the passage that with the help of RFID tags，peopleD．
A．won't feel shy at parties any longer
B．will have more time to make friends
C．will have more energy for conversation
D．will have no trouble getting information about others
59．We can infer from the last paragraph that RFID technologyB．
A．will not be used for such matters as buying milk
B．will be widely used，including for buying milk
C．will be limited to communication uses
D．will probably be used for pop music
60．The writer writes this passage toA．
A．predict the uses of RFID technology
B．help people be certain of the uses of RFID technology
C．explain the good points brought about by RFID technology
D．warn people of the possible danger in using RFID technology．

4．After 14days and more than 19，000miles，American Steve Fossett has finally made hot-air ballooning history．On his sixth attempt（尝试），and after surviving a fire which nearly force him to stop his attempt，Fossett has become the first person to fly a ballon alone around the world．
Fossett reached 117degrees longitude（经度），the line from which he had begun two weeks earlier，during the night，and his life-long dream came true．Speaking by satellite telephone from the Australian desert，Fossett said all the hard work had been worth it：‘Finally，after six flights，I've succeeded!And it's a very satisfying feeling!'
Once he had crossed the finishing line，Fossett continued across Australia until daylight allowed him to find a safe place to land．But strong winds then forced the balloon to stay in the air a while longer．‘Balloon landings are always difficult，'said Joe Ritchie，Fossett's mission controller，‘but at last Steve landed safely，early on Thursday morning．'
Besides ballooning，Fossett holds world records in sailing and flying planes．He has also swum the English Channnel and driven in the Le Mans 24-hour car race．With his balloon adventure behind him，Fossett is already planning his next trip．He wants to fly an altitude of 18kilometres．But his mission controller，Joe Ritchie said：‘I'm going to have a serious talk with Steve about this．It frightens me，to be honest．"

58．Which of the following is true according to the text？B
A．Ritchie stayed with Fossett on the flight．
B．The flight finished where it had started．

B．Ritchie is a serious man．
C．Ritchie is not as brave as Fossett．
D．Fossett's next trip is more dangerous．
60．Which of the follwing can be the title of the text？B
A．Happy Landing
B．A Man For Challenges
C．No Attempt，No Success
D．Practice Makes Perfect．

If you watch the sky about an hour after the sun goes down，you may see some"moving stars"．But they aren't real stars．They're satellites，a machine that has been sent into space and goes around the Earth，moon，etc．And the biggest of all is the International Space Station （ISS）．
The ISS is the biggest satellite because scientists want to live on it．They think that the best way to learn more about space is to live there．The space shuttle Discovery has taken off from the Kennedy Space Center in Cape Canaveral，Florida several times and carried a few groups of astronauts to the International Space Station．
When the space station is finished，it will be like a city in space．People will stay and study there with many of the things they have at home．Laboratories，living rooms and power stations are being built．The ISS is the most expensive space program ever．Millions and millions of dollars are being spent on it every year．
Scientists hope that the ISS will be a stepping stone for future space exploration．"The ISS will help us better understand the human body，explore （know more about） space and study the earth．It can help us make life on the earth better，"said Kathryn Clark，an ISS scientist．
Sixteen countries are in the program：The US，Russia，Canada，Japan，Brazil and 11European countries．China is not an ISS country，but it has helped with some of the experiments．In 2003，China sent some rice up to the ISS to find out what space would do to it．
Twenty Chinese students talked directly to an astronaut （spaceman） in the International Space Station （ISS） on radio in Nanjing，capital of east China's Jiangsu Province on Sunday，2007．The 20students，aged 10to 19from Shanghai，Guangzhou and Nanjing，began talking to Clayton C．Anderson，a 48-year-old American astronaut at 18：50p．m．at Nanjing No.3Middle School when the ISS was passing over Nanjing．
After it's finished，more than 90percnt of the world's population will be able to see the space station．So keep looking up，and maybe you'll see it get bigger and brighter．

C．buildings where electricity is produced to supply a large area
D．some countries which help send the ISS up into space
57．---Why did the scientists send up the International Space Station （ISS）？

A．would send up most of the earth people to live there
B．could talk with some Chinese school students
C．hoped to travel to Mars and Venus some day
D．wanted to live in space and do better research．

2．Earthquakes strike suddenly at any time of the day or night，there's no way to tell when．If an earthquake happens，it may cause many deaths and injuries and great damage．Decide how and where your family will get together if separate．Choose an out-of-state friend or relative that the family members can call after the quake to report where they are and how they are．Know the safe places in each room：under the strong tables，desks，or against inside walls and keep enough food，water and other things，including a flashlight，a radio，medicine and clothing．
During the earthquake，you should keep a clear head and never be too nervous to know what to do．Protect your head and neck with your arms．If possible，take a book，a pillow or any other things to protect yourself from falling glass and ruins．If you are indoors，you must immediately lie under any strong furniture．If outdoors，move to an open area away from trees，buildings，walls and power poles．In a narrow valley，move to the center of it and look up for falling stones．If you are in the car，move to the side of the road and stop the car．Do not stop near buildings，power lines and on or under the bridges．Stay in your car until the shaking stops．
Do not move badly injured（受伤的） person unless they are in danger after the earthquake．Do not use the telephone immediately unless there is a serious injury or fire．Turn on your radio for instructions and news reports．Be prepared for aftershocks．If you should leave your home，post a message inside your home telling family members where you can be found．

1．As many as one in five US teenagers have some degree of hearing loss（丧失），according to researchers．They say the problem is growing．
"Teenagers really don't pay attention to how much noise they are exposed to（接触），"Josef Shargorodsky of Brigham and Women's Hospital in Boston told Reuters．"Often people won't notice it，but even very little hearing loss may influence language development，"said Shargorodsky，one of the researchers．
The study compared surveys from the early 1990s and the mid-2000s．Each included a few thousand teenagers．In the first survey，about 15percent of teenagers had some degree of hearing loss．Some 15years later，that number had risen by a third，to nearly 20percent．
"This certainly is big news，"said Alison Grimes，an ear doctor．"Hearing loss is very common in old people，"Grimes said，but she added that it was worrying to see it happen in the younger age group．
In babies and young children，hearing problems are known to slow language development．The science is less clear for teenagers，but it is easy to imagine how being hard of hearing could influence learning，said Grimes．
The reasons for the rise are still unclear．When researchers asked teenagers about noise exposure-on the job，at school or from activities，for example-the teenagers didn't report any change．But Shargorodsky said that might not be true．"We know from before that it is difficult to ask this age group about noise exposure-they underestimate it．．"Few people would call it noise when they listen to music on their MP3player，for example．"There is a difference between what we think is loud and what is harmful to the ear，"said Grimes．
Although it's not clear that the MP3players cause teenagers'hearing loss，Grimes said it was still a good idea to turn down the sound and take short breaks from listening．

57．The writer advises teenagersA．
A．to turn the sound down
B．to stop using MP3players
C．to be clear about the problem
D．to report the change in hearing loss
58．The underlined sentence"they underestimate it．"meansB．
A．their love for music prevent them realizing the harm
B．their hearing loss is happening without being noticed
C．they think music can be taken as noise to some degree
D．they think it's harmful sometimes although it's not loud
59．Which of the following is true according to the passage？A
A．Hearing loss may lead to slow language development．
B．Hearing loss in old people is as common as in young people．
C．Researchers have already found some causes of hearing loss．
D．Teenagers know MP3is harmful，but they can't stop listening to it．
60．What is the best title for the passage？C
A．A word short and simple
B．A report by teenagers
C．A message loud and clear
D．A letter from MP3users．
