 Ever since they were first put on the market in the early 1990s,genetically modified (GM, 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would,is it the best solution?

  Despite what it promises,GM technology actually has not increased the production potential of any crop. In fact studies show that the most widely grown GM crop,GM soybeans,has suf?fered reduced productivity. For instance,a report that analyzed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production.

  Something else,however,has been on the rise. While GM seeds are expensive,GM com?panies tell farmers that they will make good profits by saving money on pesticides (杀虫剂) .On the contrary,US government data show that GM crops in the US have produced an overall in?crease in pesticide use compared to traditional crops. "The promise was that you could use less chemicals and boost production. But neither is true," said Bill Christison,President of the US National Farm Coalition.

  At the same lime,the authors of the book World Hunger; Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by pro?duction,but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile,the rise in food prices results from the increased use of crops for fuel rather than food,according to a 2008 World Bank report.

  As a matter of fact,scientists see better ways to feed the world. Another World Bank re?port concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger,because better ways out are available,among which "green" fanning is supposed to be the first choice.

(   ) 1. The author develops the second paragraph mainly         .

   A. by classification   B. by comparison

   C. by example   D. by process

(   ) 2. What does the underlined word "boost" in the third paragraph probably mean?

   A. Control. B. Evaluate. C. Obtain. D. Increase.

(   ) 3. GM companies promise farmers that they will benefit from         .

   A. practicing " green" farming

   B. less use of chemicals

   C. fair distribution of their crops

   D. using more crops for fuel

(   ) 4. Which of the following best describes the attitude of the author towards GM technology?

   A. Optimistic. B. Defensive.

   C. Disapproving. D. Casual.

 Thomas Alva Edison was the most famous inventor in American history. He had 1 ,093 pa?tents in a wide range of fields,including telecommunications,electric power,sound recording,motion pictures,primary and storage batteries,and mining and cement technology. As impor?tant,he broadened the notion of invention to encompass what we now call innovation―inven?tion,research,development,and commercialization and invented the industrial research labora?tory. Edison's role as an innovator is evident not only in his two major laboratories at Menlo Park and West Orange in New Jersey but in more than 300 companies formed worldwide to man?ufacture and market his inventions,many of which carried the Edison name,including some 200 Edison illuminating companies.

  Edison was born in 1847 in the canal town of Milan,Ohio,the last of seven children. He attended school briefly but was principally educated at home by his mother and in his father's li?brary. In 1859 Edison began working on a local branch of the Grand Trunk Railroad,selling newspapers,magazines,and candy. At one point he printed a newspaper on the train,and he also conducted chemical experiments in a baggagecar laboratory. By 1862 he had learned enough telegraphy to be employed as an operator in a local office.

  From 1863 to 1867 he traveled through the Midwest as a telegrapher. During these years he read widely,studied and experimented with telegraph technology.

In the fall of 1878,Edison devoted thirty months to developing a complete system of incan?descent electric lighting. During his lamp experiments,he noticed an electrical phenomenon that became known as the " Edison effect". In World War I,the federal government asked Edison to head the Naval Consulting Board,which examined inventions submitted for military use. Edison worked on several problems,including submarine detectors and gun location techniques.

  By the time of his death in 1931,Edison had received 1 ,093 U. S. patents,a total still un?touched by any other inventor. Even more important,he created a model for modern industrial research.

(   ) 1. How many fields in which Edison had patents are mentioned in the first paragraph?

   A. a film poster   B. a guidebook

   C. a biography   D. a blog

   A. No inventors in America have more patents than Edison up to now.

   B. Edison spent thirteen months developing incandescent electric lighting.

   C. Edison traveled through the Midwest as a telegrapher from 1863 to 1868.

   D. Edison was the oldest child of all the seven in his family.

(   ) 5. The best title for the passage may be         .

   There's more misery in people's lives than a decade ago. So says a new study on life's negatives from the University of Chicago's National Opinion Research Center,which conducts social science research for government agencies,educational institutions,nonprofit organizations and private corporations.

  The researchers surveyed 1,340 people about negative life events and found that the 2004 respondents had more troubles than those who were surveyed in 1991.

  "The expectation would have been that problems would have been down," says Tom Smith,the study's author. He says good economic years during the 90s would have brought an expectation of fewer problems,not more.

  Overall,the percentage that reported at least one significant negative life event increased from 88% to 92% . Most of the problems were related to increased incidents of illness and the inability to afford medical care,unemployment,and troubled romantic relationships.

  On a more positive note,fewer of those surveyed reported having trouble with crime or the law.

  Some of the problems outlined in the study were more complicated than just a single bad event. For instance,the inability to afford health care rose from 7% in 1991 to 11% in 2004. Those who said they lacked health insurance increased from 12% to 18% . On the romantic front,the percentage that reported breaking up with a steady partner doubled from 4% to 8% .

  But people shouldn't despair even if there is trouble around them. Bad experiences don't necessarily make people unhappy,says Jonathan Haidt,an associate professor of psychology at the University of Virginia and author of the new book The Happiness Hypothesis.

  He advises a threepoint checkup on the state of personal relationships,the work environment and control over daily life,because improving those areas will boost happiness.

(   ) 5. Which of the following verbs can be used instead of "boost" in the last paragraph?

   A. Increase. B. Reduce. C. Make. D. Find.

(   ) 6. It can be inferred from the passage that         .

   A. the economy has nothing to do with people's happiness

   B. people's problems were probably not only one single bad event

   C. most of the people's personal problems are related to the money

   D. people have a lot of trouble with crime or law

(   ) 7. Which of the following statements may NOT be found in the book The Happiness Hypothesis?

   A. When you come across the trouble,do not lose heart.

   B. Working environment and daily life should be paid much attention to.

   C. It is unnecessary for us to think about the conditions of personal relationships.

   D. Unhappy experience may not surely make people upset all the time.

(   ) 8. In your opinion,the best title for this passage may be         .

   A. Unhappiness Has Risen in the Past Decade

   B. The Problems,the Solutions

   C. The Biggest Problems in the World

   D. What's Your Life Look Like
