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.

| Subject Slimming down classics? | |
| Mr. Handsome  2007-5-12&24 AM | Orion Books,which decides there is a market in creating cut-down classics(经典著作)，is slimming down some novels by such great writers as L.Tolstoy,M.Mitchell and C.Bronte.Now,each of them has been whittled down to about 400 pages by cutting 30 to 40 per cent of the original,with words,sentences,paragraphs and,in a few cases,chapters removed.The first six shortened editions,all priced at ￡6.99 and advertised as great reads “in half the time”,will go on sale next month,with plans for 50 to 100 more to follow.The publishing house believes that modern readers will welcome the shorter versions. |
| Mr. Edwards  2007-5-12 9:40 AM | Well,I’m publisher of Orion Group.Thanks for your attention,Mr.Handsome. I must say,the idea developed from a game of “shame”in my office.Each of us was required to confess(承认)to the most embarrassing blanks in his or her reading.I admitted that I had never read Anna Karenina and tried but failed to get through Gone with the Wind several times.One of my colleagues acknowledged skipping(跳读)Jane Eyre.We realised that life is too short to read all the books you want to and we never were going to read these ones. As a leading publishing house,we are trying to make classics convenient for readers but it’s not as if we’re withdrawing the original versions.They are still there if you want to read them. |
Ms.Weir 2007-5-12 11:35 AM | I’m director of the online bookclub www.lovereading.co.uk. Mr.Edwards,I think your shortened editions is a breath of fresh air.I’m guilty of never having read Anna Karenina,because it’s just so long.I’d much rather read two 300-page books than one 600-page book.I am looking forward to more shortened classics! |
| Mr. Crockatt  2007-5-124:38 PM | I’m from the London independent bookshop Crockatt & Powell. In my opinion,the practice is completely ridiculous.How can you edit the classics?I’m afraid reading some of these books is hard work,and that is why you have to develop as a reader.If people don’t have time to read Anna Karenina,then fine.But don’t read a shortened version and kid yourself it’s the real thing. |

Britain is set to face an increase in cold winters, with up to one-in-seven hitting the UK with longer periods of time when temperatures are below freezing, a study has suggested．The prediction was based on research that found out how low solar activi
ty affected winter weather patterns．
However, the researchers were eager to stress that their findings did not suggest that the region was about to fall suddenly into a "little ice age"．The findings appear in the journal Environmental Research Letters．"We could get to the point where one-in-seven winters are very cold, as we had at the start of last winter and all through the winter before last," said co-author Mike Lockwood, professor of space environment physics at the University of Reading．
Using the Central England Temperature （CET） record, the world's longest instrumental data series that dates back to 1659, the team said that in general temperatures during recent winters had been obviously lower than the longer-term temperatures．"The mean CET for December, January and February for the recent relatively cold winters of 2008 ~ 2009 and 2009~2010 were 3．50℃ and 2．53℃ respectively," they wrote．
"However, the mean value for the previous 20 winters had been 5．04℃．The series of lower winter temperatures in the UK during the last three years had raised questions about the probability of more similar, or even colder, winters occurring in the future．"
Last year．Professor Lockwood and colleagues published a paper that found a link between fewer sunspots and atmospheric conditio
ns that "blocked" warm westerly winds reaching Europe during winter months, opening the way for cold easterly winds from the Arctic and Russia to sweep across the region．Professor Lockwood, while acknowledging that there were a range of possible meteorological factors （气象因素） that could influence blocking events, said the latest study moved things forward by showing that there was "impro
vement in the predictive skill" when solar activity was taken into consideration．

| B．Meteorological factors hardly have any influence on blocking events． |

| A．Another big danger approaching the UK |
| B．Research finds out solar activity is to blame for the cold |
| C．UK faces more cold winters due to weaker solar activity |
| D．Changes in weather patterns should be responsible for low solar activity |
