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 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 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.The phrase "communications blackout" in paragraph 1 most probably refers to during the 2012 Olympics.

At 20 year of age F.W. Woolworth found work in exchange for room and board at a local dry goods store , and after his employers held a successful clearance sale he saw the possibilities of a discount store. His key improvements were having the goods on open display instead of behind the counter , and having prices plainly marked instead of bargaining.
With borrowed funds he opened his first F.W. Woolworth store in the suburb of Utica, New York in 1879, but the store closed the following year . Deciding that his problem had been a poor location. He opened a new store in downtown Lancaster, Pennsylyania in 1881. Within months he was opening multiple stores in business partnerships with local retailers,and within a few years Woolworth was a millionaire. In 1909 he opened his first store in England, and in 1913 the company opened its new headquarters in New York’s Woolworth Building—then the tallest building in the world.
Woolworth had a deep fear of dentists , allowing his teeth to rot ,and died of a dental(牙齿)lunch counters in many stores , Woolworth was America’s largest restaurant chain through the 1940s. The company peaked as the world’s largest department store chain in the late 1970s, with more than 4 . 000 stores. By the late 1990s business was sputtering (喷溅), and the company closed all of its American department stores,renamed itself Venator, and sold the Woolworth Building . In 2003 Venator renamed itself after the company’s most successful division, Foot Locker, Inc .

For the last couple of weeks , I had been stuck in front of my computer working on a project that was very important to me . My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead , I was feeling rather depressed . I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie,but to no avail. It was only when I turned to meditation(沉思) for a solution that the answer came to me : turn to nature!
The very next day , I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve , even though it was pouring with rain . Within a couple of minutes I felt alive again.To be honest . I felt like a young school girl again and had to stop myself from hopping along the path singing , “I’m singing in the rain.”a song I used to sing when I was a child . I think as adults we often try too hard to control our inner children and as a result we restrain(限制)our own spirits , which only leads to depression and stress.
Interestingly,it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels. But this does not happen when they spend a similar amount of time walking in a busy city centre .

So much to do, so little time．So much information, so little time to read．In this age there is more information than ever before．There is not enough time to read everything we want to read．However, you can take in and understand more information in shorter time through speed-reading．This article will not make you read 3,000 words per minute, but it will show you how to increase your speed greatly．You will also learn the basic techniques of speed reading, along with the dos and don’ts of speed-reading．
When you first learned to read, you would say the word out loud and sound it out．Then you might whisper the word because people can become annoyed when you read aloud．The stage you are now at is saying the word in your head．Most people tend to read this way．Saying the word in your head will cut your reading speed tremendously （极大的）．
How do you calculate your reading speed? The speed is measured by how many words per minute you can read．Get some reading material, preferably a book．Find out how many words are on the page．Time yourself one minute．Start your timer and start reading．When the timer sounds, stop at once．If you counted 500 words on the page and you read half of the page, then you are probably reading at 250 words per minute．
The first thing about speed-reading is looking at the word and recognizing it．Don’t say the word in your mind, just look at it and recognize its appearance．Later you will recognize groups of four words or more to increase your speed．This is the first and most important step in speed-reading．
The next step is technique．As with any other skill, speed-reading requires technique．You should first be sitting up straight with your book on a horizontal （水平的） surface, such as a table or desk．Next, should be able to see the entire page．This is necessary if you want to recognize clumps of words．Lastly, you should be focused．It’s hard to read with a lot of noise．Find a quiet place to read．This will help your understanding of the text．You need something to guide your eyes while reading．Then right, you should use your hand．Remember when you were little, you would read using your finger．That is a great technique, only now you’re using your hand to underline each line．Move your finger smoothly across page．No need to go rush, start out slow．Keep your eyes focused on words as you recognize them while using your hand as a guide．This will increase your speed．
The third step is practice．Practice makes perfect．Set time intervals．Read using different techniques,
but make sure you understand what you’re reading．Which of the following statements is true according to the text?
| A．Now there is limited information than ever before． |
| B．Now conditions ask people to use less time to know more information． |
| C．Now people can read what they like． |
| D．The less you read, the more time you will spend． |
The underlined sentence “you should be focused” in the fifth paragraph means that ______．
| A．a person should devote his attention to it while reading |
| B．your feelings will be hurt while reading |
| C．a person should smooth away difficulties while he reads |
| D．you should pay attention to your faults while you are reading |
To speed up your reading, you should_________．
| A．sit up straight with your book flat and use something to guide your eyes |
| B．say every word out loud and sound it out |
| C．know it is necessary to read quickly |
| D．underline some important words while you say them |
Beijing—（13, July） China sent up a new data relay satellite（数据中继卫星）, Tianlian I-02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province．The new satellite will promote the country’s satellite communication network for space docking（对接）．
The satellite was launched on a Long-March-3C carrier rocket at 11:41 p．m．, sources at the centre told Xinhua News Agency．The satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit （地球同步转移轨道）．
Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country’s second data relay satellite．The first, Tianlian I-01, was launched on April 25．2008．
The two satellites will form a network to improve communications between China’s spacecraft and bases on Earth, according to the centre．They will also be used to help the nation’s first space docking, scheduled for the second half of this year．
As planned, China will launch space module Tiangong-I, which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county’s first space-docking mission this year．
Two more Shenzhou spaceships will dock with Tiangong-I next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian I series data relay satellites．
“The new satellite can cover a greater area to track and command the country’s space vehicles in low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position in outer space．Only three satellites of this kind are needed to form a global communication network, and China has two now．” Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said．
The satellite could also equip astronauts with real-time communications, which will benefit the country’s future manned space flights, he said．What is the main purpose to send up Tianlian I-02 ?
| A．To test the function of a Long-March-SC carrier rocket． |
| B．To carry some astronauts into space to do some research． |
| C．To send more information and clearer pictures to mobile phones on the earth． |
| D．To promote the country’s satellite communication network for space docking． |
From the passage we know．
| A．one more such satellite is needed to form a global communication network |
| B．the satellite was developed by China Manned Space Engineering Office |
| C．it was less than three years since China launched its first date relay satellite of this kind |
| D．the satellite could help track and command space vehicles in orbits because it’s lower in position |
Which of the following is TRUE according to the news report?
| A．Shenzhou Ⅷ is a manned spaceship． |
| B．Tiangong-I will dock with three Shenzhou spaceships next year． |
| C．the satellite is of great importance to China’s space exploration． |
| D．china’s first space docking will be done in the second half of next year． |
The best title of the passage could be___________．
| A．China Launched a New Space Shuttle |
| B．China’s Plan for Space Exploration |
| C．China’s Progress in China’s Space Exploration |
| D．New Satellite Helps China’s Space Exploration |
October 15th is Global Handwashing Day．Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap．
Experts say people around the world wash their hands but very few use soap at so-called critical moments．These include after using the toilet, after cleaning a baby and before touching food．
Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap．The goal, they say, is to create a culture of handwashing with soap．The organizers say all soaps are equally effective at removing disease-causing germs．They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap．Rub it into all areas, including under the fingernails．Then, wash well under running water．Finally, dry your hands with a clean cloth．
The Partnership says soap is important because it increases the time that people spend washing．Soap also helps to break up the dirt that holds most of the germs．And it usually leaves a pleasant smell, which increases the chances that people will wash again．
It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine．It could help reduce cases of diarrhea, which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half．What does the author intend to tell us in the passage?
| A．To keep healthy by washing hands． | B．To wash hands with soap． |
| C．To take action to wash hands． | D．To wash hands often． |
Which of the following is the right way to wash hands?
a．Washing hands well． b．Covering hands with soap． c．Drying hands．
d．Rubbing hands with soap．e．Wetting hands．
| A．a--c--b--e--d | B．e--d--a--b—c |
| C．a--c--b--d--e | D．e--b--d--a--c |
．Which fact can NOT explain why soap is important?
| A．It gives people a longer handwashing time． |
| B．It helps to remove a lot of germs from hands． |
| C．It attracts people to do more handwashing． |
