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 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 sea 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 than just in either northern or southern regions.

This surprised the researchers from the University of Bern. Scientists have long assumed 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 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(影響) 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 infer 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 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 the best title for the passage?

A. A 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 during the 30,000-year long ice age.

My l4-year-old son, John, and I spotted the coat which was hanging at a secondhand clothing store in Northampton Mass.

The coat had beautiful tailoring, a Fifth Avenue label and a(an)   37  price of $28, which was popular just then with   38 , but could cost several hundred dollars new.

John   40  the coat to school the next day and came home wearing a big smile. “Did the kids like your coat?” I asked. “They loved it,” he said,   41  folding it over the back of a chair and smoothing it flat. Over the next few weeks, a   42  came over John. Agreement replaced contrariness (作對) and reasoned discussion replaced fierce   43 . He became more mannerly and   44 , eager to please. He would generously loan his younger brother his tapes and lecture him   45  his behavior.
When I mentioned this incident to his teacher and   46  what caused the changes, she said laughing. “It   47  be his coat!” Another teacher told him she was giving him a good   48  not only because he had earned   49  but because she liked his coat. At the library, we ran into a friend “Could this be John?” he asked surprisingly,   50  John’s new height, assessing the cut of his coat and extending his hand, one gentleman to another.
John and I both know we should never   51  a person’s clothes for the real person within them.   52  there is something to be said for wearing a standard of excellence for the world to see and for   53  what is on the inside to what is on the outside.
For John it is a time when it is as easy to try on different approaches to   54  as it is to try on a coat. The whole world, the whole future is stretched out ahead, a vast landscape   55  all the doors are open. And he could picture himself walking through those doors wearing his wonderful, magical coat.

C
In the 1920s demand for American farm products fell, as European countries began to recover from World War I and started austerity (緊縮) programs to reduce their imports.The result was a sharp drop in farm prices.This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient.They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods.The prices of the items farmers bought remained constant, while prices they received for their products fell.These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1939s.
In 1929, under President Herbert Hoover, the Federal Farm Board was organized.It established the principle of direct interference (干預(yù)) with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers.
President Hoover's successor attached even more importance to this problem.One of the first measures proposed by President FranklinD.Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was later passed by Congress.This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use.A deliberate shortage of farm products was planned in an effort to raise prices.This law was declared unconstitutional (違背憲法的) by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people.However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation.The Roosevelt Administration believed that rebuilding the nation’s soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens.Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid (雜交) grain, and fertilizers.
53.What caused the problem in the demand for American farm products?
A.The effect of the Great Depression.
B.The shrinking of overseas markets.
C.The destruction caused by the First World War.
D.The increased exports of European countries.
54.The word “successor” refers to ______.
A.President Hoover           B.US Secretary of State
C.President Franklin          D.US Secretary of Agriculture
55.The Agricultural Adjustment Act encouraged American farmers to ______.
A.reduce their scale of production        B.make full use of their land
C.a(chǎn)djust the prices of their farm products  D.be self-sufficient in agricultural production
56.The Supreme Court rejected the Agricultural Adjustment Act because it believed that the Act ______.
A.might cause greater shortage of farm products
B.didn't give the Secretary of Agriculture enough power
C.would benefit neither the government nor the farmers
D.benefited one group of citizens at the expense of others

BEIJING — The rescue operations at a coal mine accident have ended with 105 miners dead.The State Council has organized an investigation team to probe (調(diào)查) into what caused the disaster in the city of Linfen, North China’s Shanxi Province.Preliminary investigations show the illegal mining of an unauthorized seam, and the number of miners who had been sent down the shaft far exceeded its capacity.

This mine was found to have long disregarded the rules to steal state coal, and did not have a list of miners employed to check the number of miners missing after the accident.

      How did such a coal mine get all the necessary licenses for production? How did it pass the three safety inspections the local government organized last month?

In response to this disaster, the Shanxi governor promised to set up hotlines for people to report illegal coal mines and rewards as high as 100,000 yuan for tip-offs.

We appreciate the action this governor has taken to solving the coal mining problems, and we believe that the reporting scheme will help to stop the existence of illegal coal mines.

But at the same time we have reason to question how governments at various levels supervise these mines.

The sad fact that such a mine with serious safety problems could pass three consecutive local government safety inspections in a month is enough to tell us how ineffective the safety inspections were.

What if these inspections were just a formality? What if the inspectors were bribed by the mine owners to turn a blind eye to the safety dangers? We can well imagine what would happen if reports about mine problems were handled by such officials.

So a thorough probe must find out who are responsible for the death of so many miners.A real safety inspection and management system must be established to guarantee that safety dangers will be removed.

1.What is NOT one of the causes of this coal mine accident?

A.The workers didn’t operate properly.

B.The mine didn’t obey the rules to mine for coal.

C.A lot more miners than allowed were working under the mine.

D.The safety inspections were ineffective.

2.According to the writer, who should be further investigated?

A.Mine owners and miners.

B.Miners’ families and mine staff.

C.Government officials and safety inspectors.

D.The Shanxi governor and miners.

3.What can we infer from the passage?

A.More than 105 miners died in the disaster.

B.Some other coal mines like this one exist in Shanxi province.

C.Safety inspectors just turned a blind eye to hidden dangers.

D.The three inspections were only a formality.

4.What does the underlined word “tip-offs” probably mean in Paragraph 4?

A.Some warnings.

B.Some money for one’s service.

C.Some secret information.

D.Some pieces of advice.
