Last Sunday, Aron Ralston, an experienced hiker and mountaineer, set off to walk alone through the Bluejohn desert canyon (峡谷) in Utah. He was planning an eight-hour, 21–kilometer hike. While he was climbing through a narrow part of the canyon, a big stone weighing about 400 kilos fell and trapped his right arm.
When he failed to return to the mountain camp where he was staying that night, people simply thought he had decided to camp out somewhere in the canyon. When he still had not returned by Tuesday, the alarm was raised, A search party set out on Wednesday evening, but there we no sign and his family began to fear the worst.
In fact, Ralston, 27, was lying trapped in the canyon. By Tuesday, he had run out of water. By Thursday, he realized that he would not survive unless he took unusual action, so he used his pocket knife to cut his arm below the elbow (肘). He then climbed down to the bottom of the canyon. There he met two other hikers, who helped him back to safety. He received some help at a local hospital before being carried to St. Mary’s hospital in Grand Junction, Colorado for surgery.
Ralston’s astonishing survival brought equal amounts of praise and criticism. While praising the climber for his bravery and calm, experts also pointed out he had broken the first rule of outdoor pursuits. He had failed to leave words with anyone of where he was going that day.
This was in fact Ralston’s second near-death experience. In February, he was buried up to the neck in snow by an avalanche (雪崩) while skiing in the Colorado Rockies. Ralston not only managed to dig himself out but he also rescued his skiing companion, who had been completely buried in the snow. Ralton rescued himself and his friend in less than 15 minutes.According to the passage, a “hiker” is probably someone who _______.

Tamiflu does not kill but prevents H1N1 from further proliferation (繁衍) till the virus limits itself in about 1-2 weeks (its natural cycle)．H1N1, like other Influenza A viruses, only infects the upper respiratory tract and proliferates (only) there．The only way of entry are the nostrils(鼻孔) and mouth/ throat．In a global epidemic of this nature, it's almost impossible not coming into contact with H1N1．
Contact with H1N1 is not so much of a problem as proliferation is．
While you are still healthy and not showing any symptoms of H1N1 infection, in order to prevent proliferation, some very simple steps can be practiced:
1．Frequent hand-washing．
2．"Hands-off-the-face" approach．Resist all temptations to touch any part of face (unless you want to eat or bathe)．
3．Gargle(漱口) twice a day with warm salt water (use Listerine if you don't trust salt)．H1N1 takes 2-3 days after initial infection in the throat/ nasal cavity to proliferate and show characteristic symptoms．Simple gargling prevents proliferation．In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one．Don't underestimate this simple, inexpensive and powerful preventative method．
4．Similar to 3 above, clean your nostrilsat least once every day with warm salt water，Which is very effective in bringing down viral population．
5．Strengthen your natural immunity with foods that are rich in Vitamin C ．If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption．
6．Drink as much of warm liquids as you can．Drinking warm liquids has the same effect as gargling, but in the reverse direction．They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm．
7．All these are simple ways to prevent, within means of most households, and certainly much less painful than to wait in long queues outside public hospitals．
57．What part of a person’s body do H1N1flu viruses mainly infect?
A．one’s lung B．the upper respiratory tract
C．one’s heart D．one’s throat and lung
58．H1N1 flu viruses go into our bodies by ________．

C．pay more attention to
D．calculate the number of money
60．The author presents this passage by ______．

The words of Gandhi, Einstein and other great thinkers are to be quoted in service announcements on London’s Underground．
Transport for London has asked Turner Prize-winning artist Jeremy Deller to edit a list of mottos to be used by tube drivers．Gandhi’s “there is more to life than increasing its speed” and the artist Cezanne’s “we live in a rain-bow of chaos” are among the quotes．Deller hopes they will make passengers’ journeys a bit more thought-provoking(发人深省的)．
Deller’s original plan was to abolish all public announcements for a day．“It makes me feel annoyed,” he said．“It’s like some psychological warfare(战争 ) on the passengers．”
But his idea was refused by the manager of Transport for London, who instead agreed to the plan of replacing some announcements with something more human and attractive．
Sally Shaw, who is running the scheme for Transport for London, says it is part of an attempt to improve day-to-day interaction and rely less on automated announcements．
“I think everyone has their own little philosophy on their journeys．And if we can get more of that out in the air, that would be great,” she said．
Susy Wells, one of the drivers to test the idea out on the London Underground, is also enthusiastic about it．
She said, “I like to make my own announcements and it’s nice to get passengers to think as well．”
What’s more, some quotes are helpful to the drivers．They help the passengers become more understanding about the drivers’ work．
The quotes such as Thomas Fuller’s “a stumble(绊脚) may prevent a fall” are popular for helping explain why a little inconvenience was sometimes necessary to keep the system safe．
53．The underlined phrase “tube drivers” probably means______．
A．taxi drivers B．subway drivers C．truck drivers D．bus drivers
54．Why did Deller want to abolish all public announcements on the underground?
A．Because they cause a war among passengers．
B．Because the public announcements make Deller tired．
C．Because the public announcements are dull．
D．All public announcements are not suitable for the passengers．
55．The reason why the sayings are to be quoted on London’s Underground is ______．
A．that everyone has their own life motto
B．that sayings are believed to be more human and attractive
C．that sayings can help develop spiritual civilization in London
D．that saying can make drivers think more
56．The best title of this passage would be _____．
A．Changes on London’s Underground
B．Culture on London’s Underground
C．Some Quotes Seen on London’s Underground
D．Introduction to London’s Underground
The devastation of Typhoon Morakot over Taiwan and eastern China is a reminder that the northwest Pacific is the most dangerous region in the world for tropical storms．The worst of these are typhoons, which are the same as hurricanes in the Atlantic and eastern Pacific, or cyclones in the Indian Ocean and Australia．They all have winds of more than 118km/h (73mph) spinning around a central core．
These storms start off as a mass of thunderstorms in the tropics outside the Equator．Given the right conditions, they form a bigger and more organised storm and feed off warm seas at more than 26．5C (80F) to get the fuel that they need to become a fully-fledged(羽毛丰满的) typhoon, hurricane or cyclone．Each storm is like a heat engine, extracting heat from the warm, humid air over the sea and turning it into phenomenal amounts of energy — equivalent to about 200 times the entire world’s electrical generating capacity．But warm, moist air is not enough — these storms also need slack winds aloft, because strong high-altitude winds can rip off the top of the storm clouds and send the entire storm tumbling（翻跟头）．
The damage from tropical storms often comes from their winds, or the storm surges from the sea as the winds pile up water into a huge battering ram(冲击夯) that floods coastlines．But the devastation from Typhoon Morakot came from its unbelievable rainfall — about a year’s average rain in some places — that set off landslides and mudslides．
45．According to the first paragraph, the common point among typhoons,hurricanes and cyclones is _______．
A．that they all come from the oceans
B．that they all have winds of over 118km/h spinning around a central core

46．Which of the following is the best title of this passage?
A．Typhoon Morakat devestates Taiwan and eastern China
B．How is the typhoon formed?
C．Typhoon Morakot was how to devestate the areas it travelled
D．How terrible is Typhoon Morakat!
47．The devastation from Typhoon Morakot is mainly from ______．
A．its wind B．its rainfall
C．landslides and mudslides D．the storm
48．It can be inferred from the passage that ______．
A．Taiwan is off the northwest Pacific
B．the damage from tropical storms often comes from their winds
C．tropical storms often happen
D．tropical storms only need warm, moist air
Do you know of Guo Degang? In recent months he has become well known in China as a crosstalker．He has never performed on TV before, but attending his crosstalk performance is becoming increasingly fashionable in Beijing, especially for youth and school children．
Guo arrived in Beijing from Tianjin in 1995 and came across a teahouse where he found several young people performing crosstalk．Being a crosstalker himself, he couldn’t help taking to the stage．Gradually, more and more people came to the teahouse to see him perform．He soon found himself playing to audiences numbering more than 100 in a teahouse that could only contain 80．
As his popularity grew, Guo thought over the future of his art．“Traditional crosstalk is at least half an hour long, but performances are no longer than five minutes on TV, which kills much of the story．TV is part of the fast-food culture and crosstalk is a face-to-face art form — it needs interaction (交流), and is not suited to TV,” Guo said．He decided to bring it back to its roots： the teahouse and theater．
In 1996, Guo and some young crosstalk actors founded Deyun Crosstalk Association．Over the next ten years, the association organized countless performances in teahouses across Beijing．Despite their growing popularity, Guo ensured (确保) that ticket prices were kept low to make the art form accessible to everyone．Tickets to his performances are still 20 yuan today．And in keeping with technology and modern times, the association set up a BBS site on the Internet where fans could download recordings and discuss performances with actors．
He hopes that through their efforts, more young people will learn to appreciate crosstalk and perhaps train to be crosstalkers themselves．

Scientists in Israel have discovered a new way to test for water pollution by "listening" to what the plants growing in water have to say．By shining a laser beam(激光束) on the tiny pieces of algae(海藻) floating in the water, the researchers said they hear sound waves that tell them the type and amount of pollution in the water．
"It is a red light, telling us that something is beginning to go wrong with the quality of water," said Zvy Dubinsky, an aquatic biologist at Israel's Bar Ilan University．"Algae is the first thing to be affected by a change in water quality．"
As water sources deteriorate worldwide, the testing of algae could be used to monitor water quality faster, more cheaply and more accurately than techniques now in use, Dubinsky said．The secret is to measure the rate of photosynthesis(光合作用) in the algae, meaning the plant's ability to transform light into energy．During photosynthesis, plants also release oxygen into the air．
Dubinsky's technique is easy to perform because of the over-abundance of algae in the planet's water．Most of the oxygen in the atmosphere comes from algae．A prototype tester shoots a laser beam at water samples to stimulate photosynthesis in the algae．But not all of the laser's heat is used．
Depending on the condition of the algae and the rate of photosynthesis, some of the heat is shot back into the water, creating sound waves, Dubinsky said．With a special underwater microphone, researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water．
"Algae suffering from lead poisoning, like waste discharged from battery and paint manufacturing plants, will produce a different sound than those suffering from lack of iron or exposure to other toxins," said researcher Yulia Pinchasov．
72．To study water quality, scientists choose algae mainly because．
A．algae is most easily affected by pollution
B．most oxygen is produced by algae
C．the amount of algae is decreasing
D．algae is a kind of plant floating in the water
73．When Dubinsky studied water quality, he mainly focused on．
A．the amount of laser used by algae
B．the rate of photosynthesis in the algae
C．the condition of the algae
D．the heat of laser used by algae
74．After the study, scientists proved that．
A．the increase in population is caused by lack of water
B．global warming causes water resources to reduce worldwide
C．algae can show the type and amount of pollution in the water
D．algae is dying out in the ocean around the world
75．What would be the most suitable title for the passage?
A．Water pollution is reduced with the growth of algae
B．Pollution makes it hard for plants to make photosynthesis
C．Water pollution affects the growth of marine plants
D．Scientists listen to plants to find pollution
