within just three centuries, according to some scientists.
These scientists found that rising temperatures in some places mean humans would
be unable to adapt or survive. "" It would begin to occur with global - mean warming
of about 7℃, calling the habitability of some regions into question," the researchers
wrote in a paper.
With 11-12℃ warming, such regions would spread to include the majority of the
human population as currently distributed. Professor Steven said there was no chance
of the earth heating up by 7℃ this century, but there was a serious risk that the
continued burning of gas and coal could create the problem by 2300. ""There"s
something like a 50/50 chance of that over the long term," he said.
The study, which examined climate change over a longer period than most other
research, looked at the "heat stress" produced by combining the influence of rising
temperatures and increased humidity (湿度).
Professor Steven said climate change research had been "short-sighted" not to
realize the long-term consequences of the influence of greenhouse gases blamed for
global warming. "It needs to be paid attention to," he said. "There"s not much we can
do about climate change over the next two decades but there"s still a lot we can do
about the longer term changes." "Near 2300, we may be faced with temperature
increases of 12 degrees or even more," Professor Tony Michael said." If this happens,
our current worries about sea level rise, occasional heat waves and bushfires,
biodiversity (生物品种) loss and agricultural difficulties will appear in front of us -- as
much as half the currently inhabited globe may simply become too hot for people to
live there. "

(海啸). Along with four Haitian colleagues, Dr Hermann Fritz, a professor, travelled
around the coast of Haiti. He wanted to find out what had happened before the
evidence disappeared forever. He had heard reports and saw evidence that a wave
up to 3-meter high had hit some areas of the coast south of the capital following the
quake near Port au Prince. It had killed at least three people and engulfed (吞没)
buildings.
Dr Fritz presented some of his findings at the Ocean Sciences meeting in Portland
in the US. "This was a relatively small event," he told BBC News." Most of the deaths
were due to the earthquake, but at least three victims we know survived the earthquake
and were hit by the wave."
These three victims were a father and his two young sons. They were standing
close to the shore in Petit Paradis, watching the wave instead of heading for higher
ground. Draw-back in the water level is a sign that a big wave is coming. "It clearly
showed a lack of tsunami education," Dr Fritz said. "It was pure luck that the wrong
information did not kill more people in this case."
Despite the great damage it caused, the Haiti earthquake was not of the type
or magnitude (级) usually associated with tsunamis. It had a magnitude of 7.0.
"Generally anything over 7.5 is cause for concern," explained Eddie Bernard, a
tsunami researcher." But anything between 7 and 7.5 can cause smaller, local tsunamis."
It also occurred on land and, to cause a tsunami, it must happen under the sea.
"Anything that moves water generates a wave," said Dr Bernard. "And the deeper
the event, the bigger the wave." Dr Fritz explained that the main causes of the Haitian
tsunami were "local landslides". ""But there are fault lines in this region that are in areas
which are more likely to cause a tsunami and, if you have a much bigger landslide, you
could have a much bigger wave," he said.
B. check the damage to the coasts
C. gather evidence about the wave
D. study the power of the wave
B. they cared little about the direction of the big wave
C. they didn"t see the signs of big waves
D. they didn"t know it was time to run for higher ground
B. it was lucky that the loss wasn"t greater
C. earthquakes of the magnitude of 7.0 are common in Haiti
D. few Haitians know about tsunamis and earthquakes
B. Business.
C. Sports.
D. Entertainment.
On April twenty-second, some American children stayed out of school but they were
not punished. They were with their parents. As Faith Lapidus tells us, it was Take Our
Daughters and Sons to Work Day.
The Ms. Foundation for Women started the program seventeen years ago, in 1993.
At first it was just called Take Our Daughters to Work. Gloria Steinem and other
foundation leaders pointed to studies showing that self-image suffers as girls become
teenagers. They can lose trust in their abilities and intelligence, especially in areas like
science, math and technology. So the Ms. Foundation planned a day for parents in
New York City to show girls all the possibilities for them in the professional world.
But there was so much interest, the organizers decided to make it national.
At first, girls mostly followed their mom or dad around at work to learn about their
jobs. Later, employers and schools began to offer organized activities. But from the
beginning there were protests (反对) from parents and others about the exception of
boys. So in 2003 the day was renamed Take Our Daughters and Sons to Work.
2007 was the last year that the Ms. Foundation for Women headed the program.
Now, the event is run by a twelve-person group called the Take Our Daughters and
Sons to Work Foundation.
Carolyn McKecuen is president of the foundation. She says a total of about
thirty-three million children and adults are involved in the program. About one-third
of the adults work at large companies or nonprofit organizations. Another third are
in small businesses. The rest work in education.
Carolyn McKeeuen says the numbers from this year"s event are not final yet. But
early reports suggest that participation was up at least ten percent from last year. And
she says the foundation is hoping to find support to expand the program internationally.
She says there are lots of requests from other countries for information about how to
set up similar programs.
B. gifts are considered to be more foolish than boys
C. girls aren"t confident in some areas as they becomes older
D. girls don"t want to learn some science subjects
B. Because some parents wouldn"t like to take their daughters to work.
C. Because some employers were against parents" taking their children to work.
D. Because some schools didn"t want to give any students" time to leave school.
B. 18.
C. 14.
D. 10.
B. the Take Our Daughters and Sons to Work Day is a national in America
C. Mattel is the president of the foundation whose company makes Barbie dolls
D. lots of other countries want to set up similar programs for parents and children
the exam. Standard English is the form of English you learn in school. All written English should be
standard that means it should be clear enough for anyone in Britain to understand it. Standard English
developed as the main form. of printed English in the 15th Century. At the time, every region of Britain
used to spell w0rds differently, but printers needed a fixed spelling. Printers like Caxton chose the East
Midlands dialect form which was used in London and the South East. Soon Standard English replaced
all written dialect forms the other forms of English spoken around the country. It also replaced French
and Latin in law and in academic work. In the 18th Century, people wrote dictionaries and grammar
books which standardized spelling Dr Johnson"s Dictionary of 1755 fixed many of the spellings we
still use today. All written English should be Standard English any grammar rules you learn are for
Standard English and you will definitely need to learn them to avoid making mistakes in your work.
The rules of Standard English mean using the correct forms of words with the correct spellings.
Avoid slang words words that your teachers or friends wouldn"t understand. You"ll lose marks if
the examiners can"t understand what you say or write. Don"t use dialect words. Every region has
words or phrases that are only used there. Don"t use them in your coursework, because you won"t
be understood. Make sure you revise grammar and punctuation you have learned, and learn the list
of commonly misspelled words you have made. Cliches are ideas or sayings which have been used
so often that they"ve become boring and unoriginal. Phrases like, "As good as it gets" "At the end of
the day" "In the fullness of time" are all cliches. So are images like, "as fierce as a lion" "as cunning as
a fox". If you use them you will sound boring and unimaginative that could mean you lose marks for
writing and speaking style. So avoid cliches.
b. no grammar and spelling mistake.
c. no phrase
d. no clich e. no punctuation
A. abc. B. bcd. C. ade. D. abd.
B. the English spoken by American people.

B. the boring ideas or sayings because of being used often"
C. the long phrases which are used often.
D. all the English which is used outside of London and the southeast of Britain.
B. Standard English means people should use the words from Dr Johnson"s Dictionary.
C. All the spoken English should be Standard English.
D. Standard English replaced all written dialect forms in the 18th century.
play in the physical and spiritual development of children and Martti Bergson from the University of
Helsinki shows that playing outside, in the open air, contributes to a better development of the brain.
Thus parents must encourage their children to spend as much time as possible in the open air, and
at the same time, to ask schools and kindergartens to assure the small a playground outside. Recent
statistics (数据) and studies show an alarming increase of the number of hours spent by children in
front of the TV and the computer and a decrease of the time spent outside.
As a consequence more and more children suffer from eye problems and have to wear glasses.
Also the problem of fatness among children concerns many parents who don"t know what to do
anymore to make their children eat healthy and balanced.
Children need a space where to develop their creativity mid parents should encourage them all the
time. Too many rules hold back the child"s personality and creativity and prevent them to develop the
desire to know, to find out, to learn.
If you tell your child so many times: "Don"t do that, don"t mess the room, don"t go there ...", he
will lose the desire to do something, anything. Parents must watch their children without suffocating
(窒息) them. Should you consider they mustn"t do that or this, you have to logically explain them your
reasons and they will understand.
Through playing a child learns how to communicate, how to take decisions. Playing is connected
to the intellectual, emotional and social progress of the child. Playing lets your children learn how to
express his feelings.
B. most schools and kindergartens have no playgrounds
C. most parents encourage their children to watch TV or go surfing
D. most children spend more time on TV or tile Internet than on playing outside
B. weight problems
C. lack of creativity
D. lack of interest in their lessons
B. never to forbid children to do anything they want to do
C. to explain why when you don"t let children do something
D. to watch children playing anytime to ensure their safety
B. Playing is good for your children in many aspects
C. Teaching your children what and how to play
D. Don"t forbid your children to do anything
