naturalist Richard Mabey."Personality shapes your view of the season," he said."You may see it as a fading away,a packing up (结束),or as a time of packing in another sense-the excited gathering of resources
before a long journey."
If this is true,perhaps it tells us a little about,for instance,Thomas Hood,the 19th century English poet.
About November,he wrote:
No warmth,no cheerfulness,no healthful ease
No shade,no shine,no butterflies,no bees
November!
On the other hand,another English poet John Keats,already sensing he was seriously ill,was inspired by a late September day to pen one of the most famous poems in the English language,To Autumn.He wrote
to a friend afterwards that there was something comforting and healing about it.
According to Richard Mabey,Keats has the biological evidence on his side.Autumn is not a time of
slowing down,but a time of new beginnings and great movements of creatures.For example,just at the
moment that Keats's "gathering swallows" (in To Autumn) are departing for Africa,millions of creatures are fleeing from the frozen north like Iceland,Greenland and Russia to winter along the east and south coasts of Britain.According to scientists,before falling,the leaves transfer their chlorophyll (叶绿素) and
carbohydrates into the woody parts of the tree for safekeeping over winter.What remains are the natural
antioxidants (防老剂) in the leaves:the yellow and orange carotenoids (类胡萝卜素),and another
protective chemical specially produced for autumn,the brightred anthocyanin (花青素)．High color is not a signal of deterioration (退化) and decline,but of detox (排毒的) ability and good health.
A century after Keats,the American poet Loren Eiseley wrote in his journal:"Suppose we saw ourselves burning like maples in a golden autumn,and that we could disintegrate (分解) like autumn leaves...dropping their substance like chlorophyll.Would_not_our attitude_towards death_be_different?"
B. he missed the shining summer days very much
C. he had a negative attitude towards autumn
D. he enjoyed butterflies and bees very much
B. Fearful.
C. Doubtful.
D. Realistic.
B. they can't get enough water from the woody part
C. chlorophyll and carbohydrates have been lost through leaves
D. chlorophyll and carbohydrates have come back to the woody part.
B. Man is different from autumn leaves,which will come again the next spring.
C. Man should treat death calmly,just like autumn leaves fall to the ground.
D. Man should have a positive attitude towards death,quite different from autumn leaves.
More than 300 years ago, the British used “fall” instead of “______”.

A．spring |
B．summer |
C．autumn |

During his life Dr James Naismith worked as a doctor, taught P．E and wrote several books．While he never thought it very important, Dr Naismith is today best known for one thing．He was the inventor of basketball．
Dr James Naismith was born in Canada in 1861 and his first job was at a special sports school in the USA．One day the school principal told James he was having a problem with the students．Because of heavy snow, the students could not go outside．He told James that they needed a sport the boys could play indoors and gave the teacher two weeks to think of something．
It was on the very last day that James came up with his idea．The “birth of basketball” is said to be on December 21, 1891, when two teams from the school played the first game．It was quite different from the basketball games of today．It had 9 players on each team and footballs were used instead of basketballs．Soon after, the game changed to 5 players on each side, using special “basketballs” through nets．
Although Dr Naismith did not live to see basketball become the worldwide game it is today, in 1936, just three years before his death, basketball became an Olympic sport at the games in Berlin．
Which of the following things did Dr James Naismith NOT do?
A．Teach P．E in school． B．Write some books．
C．Work at hospital． D．Take part in the Olympic Games．
In which season did Dr Naismith invent basketball?
A．Summer． B．Winter． C．Spring． D．Autumn．
Why is December 21 thought to be the birthday of basketball?
A．It was on this day that Dr Naismith came up with his idea for basketball．
B．It was the day on which Dr Naismith was born．
C．It was the day on which Dr Naismith was asked by his boss to invent a new game．
D．It was on this day that the first game of basketball was played．
At the time of Dr Naismith’s death, which of the following was true?
A．Basketball was already a worldwide game．
B．Basketball was played with 9 players on each side．
C．Basketball was an Olympic sport．
D．Basketball was still played using footballs．
What would be the best title for this story?
A．History of Basketball B．How Basketball Has Changed
C．Father of Basketball D．Happy Birthday, Basketball
查看习题详情和答案>>Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years, the planet was much colder than it is now .During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
A new study from Switzerland throws light on where ice sheets（冰川）inched during the ice age. It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern regions.
This surprised the researchers from the University of Bern. Scientists have long assumed（假设）that most of the ice that melted was in the Northern hemisphere（半球）during the 30,000-year long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land .If surrendered by sea the ice can easily just slip into the ocean instead of building up.
The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the Northern hemisphere that ice melted, there would have been a bigger impact（影响）on ocean currents （洋流）and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too. The only reasonable conclusion, the scientists could make, was that ice melted equally in the North and the South.
It is still a mystery as to what caused the temperature changes that caused the ice to melt.
The North Pole is surrounded by land ,while the South Pole is surrounded by the Antarctic Ocean. So scientists thought that .
A．most of the ice melted in the Northern hemisphere
B．most of the ice melted in the Southern hemisphere
C．The North Pole is colder than South Pole
D．The South Pole is colder than North Pole
We can learn from the passage .
A．the ice can easily just slip into the ocean
B．volcanoes caused the ice to melt
C．melting just in the Northern hemisphere would have been impossible
D．researchers often use the computer models to help their research work
The scientists are not sure .
A．how long the ice age lasted
B．where ice sheets melted during the ice age .
C．what caused the temperature changes
D．what the earth is made up of
Which of the following is NOT right ?
A．The researchers want to know how the melting of ice might affect sea levels by the
computer model.
B．Studies show ice melted equally in the North and the South during the ice age.
C．Most of the ice melted in the Northern hemisphere（半球）during the 30,000-year long
Ice age.
D．The temperature changes caused the ice to melt.
