A. as much as B. up to C. instead of D. due to——青夏教育精英家教网—

　　Most of us 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 ago, 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 seal levels rise．Water froze again during the cold periods．

　　A new study from Switzerland sheds light on where ice sheets melted during the ice age．

　　It now seems that the ice melted at both ends of the earth, rather也all just in either northern or southern areas．This surprised the researchers from the University of Bern．

　　Scientists have long assumed(认为)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 surrounded．by sea,the ice Call easily just slip to the ocean instead of building up．

　　The researchers used a computer model to look at the ways the ice could melt And how it might affect sea levels．They compared these results to evidence(迹象)of how temperature and currents actually changed during that time．

　　The model showed that if it was only in the Northern hemisphere that ice melted, there would be a bigger effect 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 the ice melted equally in the North and the South．

　　It is still mystery(谜)as to what caused the temperature changes that caused the ice to melt．

One morning, a young man leading a goat lost his way due to the thick mist．Then he met a blind man and asked whether he also lost his way．The blind man said, “I cannot see anything．Therefore, the mist doesn’t affect me．I followed the path in my memory and it never goes wrong.”

Happily the young man led the goat following him forward．The blind man asked where he was going．He said he wanted to sell his goat．“Male or female? How many years have you kept it?” The young man spoke without too much thought, “A female goat of 3 years!”

The young man was still following the blind man when he was grasped the hand by the blind man．He shouted ,“Here is the police station! Go into it and elaborate on how you stole the goat!”

The young man had been a thief for a long time and admitted the goat was stolen by him．He asked the blind man puzzlingly, “But how do you know I am a thief?”

The blind man smiled, “I have been keeping goats for decades and can tell one of them is male or female as well as their age according to their voices．The goat you led just now is obviously a male goat, but you said female．The goat is simply a little more than one year old, but you said you had kept it for three years．Moreover, the goat will bleat totally differently when he is led by a stranger instead of his owner．So I can tell the goat does not belong to you!” Only then did the thief understand the whole thing with his head dropped down．

The blind man didn’t lost his way because _________

A．he didn’t lead a goat

B．he couldn’t see anything

C．he wasn’t affected by the thick mist

D．he had a better memory than the young man

According to the dialogue in Paragraph 2, we can know that ______

A．the blind man was a detective

B．the young man was an honest man

C．the young man familiar with the goat

D．the blind man was very careful

The underlined word “elaborate” in Paragraph 3 most probably means ______

A．express in detail B．tell a lie

C．learn by heart D．make up one’s mind

We can infer that the young man was ______after hearing the blind man’s explanation．

A．humorous B．nervous C． depressed D．satisfied
