Lead（铅） deposits, which accumulated（增加） in soil and snow during the 1960's and 70's, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated（托管） unleaded gas use in the United States, the lead accumulation world-wide has decreased greatly.
A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining（减少）.
In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasoline and thus enabled scientists to differentiate (分区) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.
In a study published in the journal Ambio, scientists found that lead levels in soil in the North-eastern United States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period.
The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed (再分配)the lead faster than the scientists had expected. Scientists say both studies show that certain parts of the ecosystem (生态系统 ) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.
1. The study published in the journal Nature indicates that ________.
A. the Clean Air Act has not produced the desired results
B. lead deposits in arctic snow are on the increase
C. lead will stay in soil and snow longer than expected
D. the US is the major source of lead pollution in arctic snow

B. By observing the lead accumulations in different parts of the arctic area.
C. By studying the chemical elements of soil and snow in Northeastern America.
D. By comparing the chemical compositions of leaded gasoline used in various countries.
4. The authors of the Ambio study have found that ________.
A forests get rid of lead pollution faster than expected
B. lead accumulations in forests are more difficult to deal with
C. lead deposits are widely distributed in the forests of the US
D. the upper layers of soil in forests are easily polluted by lead emissions

In a recently published book, I came across some exercises with interesting names such as fishbone diagrams, lotus flowers and clustering. As I used these exercises in my classes, I noticed that students were interested. They said more and wrote more. They enjoyed expressing their ideas and sharing them in groups. They were no longer passively waiting for the bell , but actively taking part in the lesson. I find that creativity can act as a way to increase participation and improve fluency.
Creativity has become a popular word in recent years. Scholars in arts, psychology, business, education and science are all working to get a deeper understanding of it. Robert J. Stemberg is a creativity specialist and Yale professor of psychology. He defines creativity as “the ability to produce work that is both new (original) and appropriate(applicable to the situation ) ”. this definition is useful, as we want our students to use language in a new way and to use it correctly and properly. Mot scholars say there are two types of creativity: big “C” creativity and small “c” creativity. Big “C” creativity refers to genius level thinking that results in artistic masterpieces and scientific breakthroughs. Small “c” creativity refers to everyday level thinking that can be used in any situation our emphasis is on the latter. While it goes without saying that any of our students could go on to be the next Picasso or Edison, our aim is to help students produce more ideas and use language in a new way. The underlined words “waiting for the bell ” in the first paragraph probably means______.
| A．longing for a phone call | B．hoping to have a bell |
| C．expecting the end of the class | D．waiting to speak in the class |
It can be inferred from the passage that the author thinks the exercises in the book were _____.
| A．popular | B．useful | C．scientific | D．creative |
When you use a familiar word in a new way, you are ________.
A creative in the sense of big “C” creativity.
B. creative in the sense of small “c” creativity..
C. not creative in the sense of big “C” creativity..
D. not creative in the sense of small “c” creativity.The main purpose of the passage is to _________.
A. show how useful the book is.
B, explain what creativity
C. discuss how one can be creative
D. tell what reaching aims at

The first reality TV show in the world was called Expedition Robinson and it was shown in Sweden in 1997. Half the population of the country watched the final event and a new kind of TV program was born. Two years later in Holland , the first series of Big Brother was filmed. Again, it was a great success and the final program was watched by 15 million people. Now more than 20 countries around the world have Big Brother or Expedition Robinson on their TV screens. The ordinary people who take part in the programs are known by millions of people in their own countries and reality TV has become big, big business.
For the TV producers, reality TV is a dream come true because many of the programs cost nothing to make. At some point, the television viewers are asked to telephone the program to vote or to apply to take part in the show. It is the cost of these telephone calls that pays for the shows. One of the most popular shows is Pop Idol. In the show a group of attractive young people are made into pop stars. TV viewers vote for their favorite person on the show. The winner makes a record and millions of copies of the record are sold. His or her pictures are published on the covers of magazines or on the front pages of newspapers, and then, they are quickly forgotten.
But not everyone is happy about reality TV. In Portugal, two TV channels got into trouble because they showed too much of the personal lives of the people in the shows. In France, reality TV is called “rubbish TV” and the TV studios of Big Brother were attacked three times in one week. In Greece, Big Brother was described as “ against human rights and civilization”. Those who take part in the reality TV shows are usually _____.
| A．common people | B．pop TV stars | C．attractive people | D．famous film stars |
Who would pay for the cost of the reality TV shows according to the passage?
| A．TV producers who make reality TV shows |
| B．TV actors who take part in reality TV shows. |
| C．TV viewers who telephone reality TV shows |
| D．TV companies which broadcast reality TV shows |
It can be concluded from the passage that ______.
| A．everyone is happy about reality TV. |
| B．reality TV will do well in many countries. |
| C．all the people in Europe are in favor of reality TV |
| D．reality TV will not be broadcast in any countries. |
The Marches were a happy family. Poverty, hard work, and even the fact that Father March was away with the Union armies could not down the spirits of Meg, Jo, Amy, and Marmee, as the March girls called their mother.
The March sisters tried to be good but had their share of faults. Pretty Meg was often displeased with the schoolchildren she taught; boyish Jo was easy to become angry; golden-haired schoolgirl Amy liked to show up; but Beth, who kept the house, was loving and gentle always.
The happy days passed and darkness came when a telegram arrived for Mrs. March. “Your husband is very ill,” it said, “come at once.” The girl tried to be brave when their mother left for the front. They waited and prayed. Little Beth got scarlet fever (猩红热) when she was taking care of the sick neighbor. She became very ill but began to recover by the time Marmee was back. When Father came home from the front and at that joyful Christmas dinner they were once more all together.
Three years later the March girls had grown into young womanhood. Meg became Mrs. Brooke, and after a few family troubles got used to her new state happily. Jo had found pleasure in her literary efforts. Amy had grown into a young lady with a talent for design and an even greater one for society. But Beth had never fully regained her health, and her family watched her with love and anxiety.
Amy was asked to go and stay in Europe with a relative of the Marches. Jo went to New York and became successful in her writing and had the satisfaction of seeing her work published there. But at home the bitterest blow was yet to fall. Beth had known for some time that she couldn’t live much longer to be with the family and in the spring time she died.
News came from Europe that Amy and Laurie, the grandson of a wealthy neighbor, had planned to be married soon. Now Jo became ever more successful in her writing and got married to Professor Bhaer and soon afterwards founded a school for boys.
And so the little women had grown up and lived happily with their children, enjoying the harvest of love and goodness that they had devoted all their lives to. The members of the March family were Father March, Mrs. March and their _______.
| A．four daughters | B．five daughters |

The twentieth century saw greater changes than any century before: changes for the better,
changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.
Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology m the application of science m has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science -- a wider and deeper knowledge in all fields of learning; in applied science -- a more reasonable sharing of material benefits, and better protection of the environment.
Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons, Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.
William Shakespeare said, “The web of our life is of a mingled yarn (纱线), good and ill together.” The above brief review of the application of only one part of human activities----- science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?Which of the following best shows the structure of the passage?
| A． | B． | C． | D． |
From the fourth paragraph, we can infer that________.
| A．a great many nuclear weapons were actually used for war |
| B．a large number of nuclear weapons should have been used for war |
| C．the author is doubtful about the ruin of human beings by nuclear weapons |
| D．the author is anxious about the huge number of nuclear weapons on the earth |
The underlined word "mingled" in the last paragraph most probably means________.
| A．simple | B．mixed | C．sad | D．happy |
What do you think the author is most likely to suggest if he continues to write?
| A．Further application of science to war. |
| B．More reading of William Shakespeare. |
| C．Proper use of science in the new century. |
| D．Effective ways to separate the good from the ill. |
