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 (日冕物质抛射) 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 the 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 (太阳耀斑) and explosions as they occur.
Professor Richard Harrison, 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 advanced 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.

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 |

B.the London Olympic broadcasting will be possibly influenced by the 2012 peak of sunspots |
C.the 2012 Olympic Games are during the solar maximum of throwing out greatest number of sunspots |

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 fresh 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 (通信) 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 (日冕物质抛射) occur in the Sun’s atmosphere, throwing out great quantities of electrically-charged (带电) matter. “A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometers 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.

The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
Professor Richard Holdaway, 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.

Mayor Boris Johnson Monday outlined plans to make London “the cleanest” by the 2012 Olympics and called for commitments from other world cities at a climate change conference. Leaders of the world's 40 largest cities are meeting in Seoul this week for a summit on combating global warming ---- the third to be held since 2005.
"What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine (内燃机)," said Johnson. He told a press conference the world's cities consume 75 percent of its energy and produce 80 percent of the emissions which cause climate change. "The problem of our planet is an urban problem," Johnson said.
He said the British capital wants to use the Olympics "to drive the greening and the improvement of our city" and noted that London is committed to reduce carbon emissions by 60 percent by 2025.
Johnson said the key measure was addressing the problems relating to domestic and commercial buildings, which accounted for 70 percent of carbon dioxide emissions in London. This involved retrofitting (翻新) ---- installing lagging (绝缘层材料) ---- in large numbers of public buildings.
Johnson proclaimed himself a "passionate cyclist" and said he would push ahead with cycle super-highways around London.
London's air quality problem, he said, was caused by vehicle emissions from 8,300 antiquated (陈旧的) diesel (柴油) buses, which could be replaced by low-carbon vehicles. There were also 32,000 taxis running on diesel fuel, which could be replaced by electric vehicles.
Johnson said there would be a substantial (实质上的) program in the next few years to produce a "cleaner, greener" bus for his city. "The age of the diesel-emitting bus has got to be over in London."
1.Which of the following statements is NOT TRUE according to this passage?
A. The used buses running on diesel will be replaced by electric vehicles.
B. London’s air quality will be improved in the near future.
C. London promises to reduce carbon dioxide emissions by 60 percent by 2025.
D. Plans have been made to solve the problem of carbon dioxide emissions.
2.What does the underlined word mean in the first paragraph?
A. discussing B. resisting C. agreeing D. supporting
3.The topic of the meeting in Seoul might be __________.
A. climate change B. London Olympics in 2012
C. global warming D. green environment
4.If the passage was continually written, the following might be __________.
A. measures to replace the old and used vehicles
B. measures to reduce carbon dioxide emissions in London
C. measures to solve housing and commercial items
D. measures to end the age of the diesel bus

高二英语单项填空中等难度题查看答案及解析
YOU probably think you know about London’s problems. The people are unfriendly, it’s way too expensive, and the food is terrible - so why do so many tourists flock (蜂拥) there?
London was named the world’s most popular city between July and September 2013. It edged out other world-famous cities such as New York and Paris, welcoming 4.9 million visitors, according to the UK Office for National Statistics.
Amazingly, this was an increase of almost 19.5 percent on 2012 - the year when the Olympics happened in summer.
So can London’s success be explained? Well, maybe. As the English writer Samuel Johnson once said, “when a man is tired of London, he is tired of life”. London life is often crazy and expensive, but if you can think of something, you can probably do it there.
Anywhere in the city, you can often look around a great museum such as the British Museum, watch a concert at a historic venue (场所) like the Royal Albert Hall, or dance the night away in a cool nightclub such as Fabric.
And it’s not just about culture – there are also world-famous sporting venues around the city. Many tourists like to watch soccer matches at stadiums such as Chelsea’s Stamford Bridge, Arsenal’s Emirates Stadium, or Tottenham’s White Hart Lane. Tourists even came to watch British tennis player Andy Murray’s famous victory at the Wimbledon tennis tournament (锦标赛) in 2013.
Yes, but what about the food? Well, even if you don’t like British food – and if you’ve never had real fish and chips, or a summer pudding, then perhaps you should wait until you’ve tried them – there is plenty of great food from all over the world available in London’s many restaurants.
London, like many of its buildings, has a long history, but also never lacks a vibrant pulse (充满活力的脉搏). All over the city, history and modernity come together to make it an essential place for tourists to discover.
1. What is the author’s main purpose in writing the article?
A. To show the effects of the 2012 London Olympics.
B. To analyze why London appeals to tourists.
C. To compare London with other world-famous cities.
D. To talk about common problems in London.
2. The underlined phrase “edged out” in the second paragraph probably means ______.
A. took the lead of
B. had a lot in common with
C. followed the example of
D. became more popular than
3. In Samuel Johnson’s eyes, life in London is probably ______.
A. relaxed B. boring
C. colorful D. challenging
4. According to the article, London is attracting many visitors from across the world, mainly because ______.
a. it is a city rich in culture and attractions
b. most local people are friendly
c. the sporting venues around the city are worthy of a visit
d. British food enjoys a good reputation among visitors

高二英语单项填空简单题查看答案及解析
About twenty of us had been fortunate enough to receive invitations to a film-studio(影棚)to take part in a crowd-scene. Although our "act" would last only for a short time, we could see quite a number of interesting things.
We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in "snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.
The next scene was a complete contrast (对比).The way it was filmed was quite unusual. Pictures taken on an island in the Pacific were shown on a glass screen. An actor and actress stood in front of the scene so that they looked as if they were at the water's edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!
Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film “Stars”!
1.Who is the author?
A.A cameraman. B.A film director.
C.A workman for scene setting D.A crowd-scene actor
2. What made the author feel cold?
A.The heavy snowfall. B.The film being shown.
C.The low temperature. D.The man-made scene.
3.What would happen in the "three minutes" mentioned, in the last paragraph?
A.A new scene would be filmed.
B.More stars would act in the film.
C.The author would leave the studio.
D.The next scene would be prepared.
