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(zhì)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(yáng)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.
【小題1】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 |
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(減少) after coronal mass ejections. |
A.So far scientists still don’t know what caused the Solar Storms. |
B.When Solar Storm happens, you’d better turn off the electrical appliances. |
C.The risk is greatest during a solar maximum when there is the greatest number of sunspots. |
D.Early warming can help minimize the harm of the Solar Storms. |
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 |
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 |

科目:高中英語(yǔ) 來(lái)源:2010年浙江溫州省一級(jí)重點(diǎn)中學(xué)高一下學(xué)期期末統(tǒng)考英語(yǔ)卷 題型:閱讀理解
If you were a pilot flying a plane, and suddenly the engine failed, would you eject (彈出), or stay in? For a pilot, the choice is very difficult. If he ejects, he is wise, but the plane crashes. If he stays in the plane, he risks his life.
Recently, Chinese Air Force pilot Li Feng, 38, faced this choice during a training exercise. It was March 7 and he was flying a Jian-10 (Flghter-10) at 4,500 meters. A warning appeared on the plane’s computer screen. He realized the plane might fail at any moment.
Li Feng did a quick check of the engine and asked the base if he could return. When the fighter was 7km away from the airport, however, the engine stopped working. The plane began to fall at a speed of 25 meters a second from an altitude of 1,160 meters.
Under Air Force rules fighter pilots may eject if their aircraft loses engine power below 2,000 meters and can’t be restarted. Before Li lost contact with the control tower, the commander in the air base asked him to eject. But Li Feng insisted on having another try.
“I knew where the deadline (to abandon the aircraft) was and was prepared for the ejection, but I decided not to give up unless the fighter was totally out of control,” Li recalled during a recent television interview.
After 104 seconds, Li was able to bring the fighter to a safe landing. The plane only suffered slight damage.
“You are a hero! Congratulations!” Li’s teacher, Xu yongling wrote in a text message to him after the landing. He said Li was a cool-headed pilot and very professional.
Li’s brave and calm act not only saved the 200 million yuan aircraft but also gave him invaluable first-hand experience of dealing with an engine emergency.
For his outstanding performance, the Air Force recently awarded him a gold medal.
【小題1】When the engine stopped working, Li Feng _________.
A.was flying a Jian-10 at 4,500 meters | B.saw a warning appeared on the plane’s computer screen |
C.was still calm and cool-headed | D.was asked to stay in, but he ejected |
A.pilots must restart it as soon as possible | B.pilots should repair it as soon as possible |
C.pilots may eject for safety | D.pilots should bring it to a safe landing |
A.Because he had no choice but to stay in the plane. | |
B.Because the fighter was not totally out of control. | |
C.Because he didn’t know how to eject. | D.Because he wanted to get a gold medal. |
A.Flying the Fighter Correctly | B.When to Abandon the Aircraft |
C.How to Deal with an Engine Emergency | D.Bring the Fighter to a safe Landing |

Short Skirts Are Out!
After decades of skimpy skirts and sleeveless tops on game days, some schools in the US are saying cheerleader uniforms will have to meet stricter dress codes when they are worn in class.
In Lake County, Florida, cheerleaders with uniforms too skimpy for the code are being asked to wear long shorts or trousers under their skirts and a T-shirt under the sleeveless tops, according to a district memo. Principals at two of Lake’s eight high schools – Leesburg and Lake Minneola – are not allowing the outfits in school at all.
Michelle Thomas, a cheerleader at Leesburg High School, was disappointed when she learned she couldn’t wear her outfit to school on game days.
“It shows that we’re a team just like all the other sports,” she said.
But the school administrators did not agree. “During the educational portion of the day, they have to meet the dress code just like every other student,” said school board chairwoman Debbie Stivender, who ordered the staff to bring the outfits into line with the dress code.
Bare midriffs are banned across the state by the Florida High School Athletic Association, but no state rules mention cheerleader miniskirts. Sheila Noone, a spokeswoman for cheerleading uniform company Varsity Brands, says the outfits haven’t become more revealing over the last 10 years. She says that the short skirts are designed to help the girls jump and kick.
“Cheerleading is athletic,” Noone said. “There’s a lot of jumping, so you won’t want a knee-length skirt that might hamper a tie touch.”
Most cheerleaders were sad to hear the news, but say they’ll follow the rules. Even male cheerleaders, whose pants and tops meet dress codes, chose not to wear their outfits to show unity.
“I understanding, because they are kind of short,” said Holly Bishop, 14, a Lake Minneola High School cheerleader, about her miniskirt. “It would have been really, really cool to wear them to school.”
【小題1】According to the new dress codes for cheerleaders in some American schools, __________.
A.bare midriffs are banned |
B.cheerleading miniskirts are banned |
C.cheerleader uniforms have switched from skirts to trousers |
D.cheerleaders have to make their uniforms less revealing |
A.School administrators believe cheerleader uniforms do not match school dress codes. |
B.Most cheerleaders show understanding of the new dress codes. |
C.Sheila Noone believes that cheerleading miniskirts are not revealing. |
D.School administrators don’t take cheerleading seriously. |
A.they hate the dress codes that other sports have |
B.they consider their uniforms special and cool |
C.they want to wear revealing clothes |
D.they will have to buy new uniforms |
