The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms.
After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物質拋射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.
Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太陽耀斑) and explosions as they occur.
Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.
72. The phrase "communications blackout" in paragraph 1 most probably refers to during the 2012 Olympics.
A. the extinguishing of the Olympic torch
B. the collapse of broadcasting systems
C. the transportation breakdown in London
D. the destruction of weather satellites
73. What can be inferred about the solar activity described in the passage?
A. The most fatal matter from the corona falls onto Earth.
B. The solar storm peak occurs in the middle of each cycle.
C. It takes several seconds for the charged matter to reach Earth.
D. The number of sunspots declines after coronal mass ejections.
74. According to the passage, NASA will launch a satellite to _________.
A. take images of the solar system B. provide early warning of thunderstorms
C. keep track of solar activities D. improve the communications on Earth
75. Which of the following might be the best title of the passage?
A. Solar Storms: An Invisible Killer
B. Solar Storms: Earth Environment in Danger
C. Solar Storms: Threatening the Human Race
D. Solar Storms: Human Activities to Be Troubled

(10·上海A篇)
The elephant was lying heavily on its side, fast asleep. A few dogs started barking at it. The elephant woke up in a terrible anger: it chased the dogs into the village where they ran for safety.
That didn't stop the elephant. It destroyed a dozen houses and injured several people. The villagers were scared and angry. Then someone suggested calling Parbati, the elephant princess.
Parbati Barua's father was a hunter of tigers and an elephant tamer. He taught Parbati to ride an elephant before she could even walk. He also taught her the dangerous art of the elephant round-up -- how to catch wild elephants.
Parbati hasn't always lived in the jungle. After a happy childhood hunting with her father, she was sent to boarding school in the city. But Parbati never got used to being there and many years later she went back to her old fife. "Life in the city is too dull. Catching elephants is an adventure and the excitement lasts for days after the chase," she says.
But Parbati doesn't catch elephants just for fun. "My work," she says, "is to rescue man from the elephants, and to keep the elephants safe from man." And this is exactly what Parbati has been doing for many years. Increasingly, the Indian elephant is angry: for many years, illegal hunters have attacked it and its home in the jungle has been reduced to small pieces of land. It is now fighting back. Whenever wild elephants enter a tea garden or a village, Parbati is called to
guide the animals back to the jungle before they can kill.
The work of an elephant tamer also involves love and devotion. A good elephant tamer will spend hours a day singing love songs to a newly captured elephant. "Eventually they grow to love their tamers and never forget them. They are also more loyal than humans," she said, as she climbed up one of her elephants and sat on the giant, happy animal. An elephant princess indeed!
65. For Parbati, catching elephants is mainly to .
A. get long lasting excitement B. keep both man and elephants safe
C. send them back to the jungle D. make the angry elephants tame
66. Before Parbati studied in a boarding school, .
A. she spent her time hunting with her father
B. she learned how to sing love songs
C. she had already been called an elephant princess
D. she was taught how to hunt tigers
67. Indian elephants are getting increasingly angry and they revenge because __________.
A. they are caught and sent for heavy work
B. illegal hunters capture them and kill them
C. they are attacked and their land gets limited
D. dogs often bark at them and chase them
68. The passage starts with an elephant story in order to explain that in India _________.
A. people easily fall victim to elephants' attacks
B. the man-elephant relationship is getting worse
C. elephant tamers are in short supply
D. dogs are as powerful as elephants
