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. Five. B. Six.
C. Seven. D. Eight.
( ) 2. The purpose of this passage is to .
A. tell us how Edison became an innovator

C. tell us about Edison's childhood
D. show us how Edison succeeded
( ) 3. You will probably find the article in .
A. a film poster B. a guidebook
C. a biography D. a blog
( ) 4. What can we learn from the passage?
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.

Many people have seen Harry Potter and The Halfblood Prince since it came out last July. And just like the readers of the Harry Potter books,the theater audience have included children,teenagers,and adults.
The Halfblood Prince is the sixth Harry Potter movie,and is based on the sixth in the se?ries of seven books written by the author J. K. Rowling. The story of the final book,The Deathly Hallows,is going to be told in not one but two movies,which will come out in 2010 and 2011.
In some ways,The Halfblood Prince is just like the other stories：Harry is again the hero fighting against the forces of evil,a lot of the action takes place at the Hogwarts School of Witchcraft and Wizardry,and there are familiar things such as the game of Quidditch (sort of like soccer,although it is played in the sky and the players ride on broomsticks) .
One of the differences with this movie is that we see less of the evil wizard Lord Voldemort,but there is still a lot of evil in the story―in fact,most movie critics say The Halfblood Prince feels "darker" than the other movies because you can feel the presence of Voldemort most of the time.
This is certainly true at the beginning of the movie,when there is an attack on London by Voldemort's followers,the "Death Eaters". Like a few other things in the movie,this was not in the book of The Halfblood Prince,and might therefore be a surprise for many Harry Potter fans.
Another difference is that the movie spends more time looking at the relationships between the students at Hogwarts. Harry,Ron,Hermione,and the others are now teenagers rather than children―there is even a little romance in the story.
Daniel Radcliffe,19, Harry Potter in the movie,said he will be "very sad" when the series movies end,but also excited because he will be able to play different roles.
( ) 1. We can learn from the passage that .
A. the focus of the final movie is to be " romance"
B. Daniel will play different roles in the final movie
C. There will be eight Harry Potter series of movies in all
D. J. K. Rowling wrote about an attack on London in the sixth book
( ) 2. The passage is mainly about .
A. the popularity of J. K. Rowling
B. The Deathly Hallows,the final book
C. the sixth movie of Harry Potter series
D. the differences between the sixth movie and the final one
( ) 3. "The Death Eaters" in Paragraph 5 are .
A. part of the evil side B. heroes against Voldemort's followers
C. Harry Potter's fans D. new friends in the Hogwarts School
( ) 4. What mainly makes the sixth movie of the series different from the others?
A. The main characters have grown up.
B. The game of Quidditch can't be seen in it.
C. The less presence of Voldemort makes viewers feel easier.
D. Harry Potter develops a friendship with Ron and Hermione.

Breaking the Code One school night this month I walked quietly up to Alexander,my 15-year-old son,and touched his cheek gently in a manner I hoped would seem casual. A year ago he would have ignored this disturbance but now he reacted impatiently and leaned back to his computer screen.
I made a mistake：breaking into my teenager's personal space. "The average teenager has pretty strong feelings about his privacy," Lara Fox and her friend Hilary Frankel told me. Ms. Frankel and Ms. Fox,both17,are the authors of Breaking the Code,a new book that seeks to bridge the generational divide between parents and adolescents. It is being promoted by its publisher as the first selfhelp guide by teenagers for their parents,a kind of "Kids Are from Mars,Parents Are from Venus'1 that explains the language and actions of teenagers. The girls dealt with issues including hanging out late,money,school pressures,smoking etc.
Personally,I welcome their opinions. The most common missteps (失策) in interacting with teenagers arise from the war between parents exercising their rights to know what goes on under their roof and teenagers firmly guarding their privacy. Teenagers can be quick to interpret their parents' remarks and respond with anger that masks their vulnerability (脆弱) . Ms. Fox said," What we want above all is your approval. Don't forget,no matter how much we act as if we don't care what you say,we believe the things you say about us."
Nancy,a New York childraising expert said she didn't agree with everything the authors suggested but found their arguments reasonable. "When your kids are saying, ' You don't get it,and you never will , ，there are lots of ways to respond so that they will listen and that is what the writers point out."
"My parents helped me see that,”Ms. Fox told me,"even though they used to stay out late and ride their bicycles to school,times have changed and the way parents educate children is different. These days there is a major fear factor in bringing up kids. Parents worry about their child crossing the street."The writers said they hoped simply to throw light on teenage thinking.
( ) 1. Why does the author mention the book"Kids Are from Mars,Parents Are from 'Venus17？
A. It is one of the bestsellers.
B. It is also written by the two girls.
C. The two books have the similar theme.
D. The two books have different opinions.
( ) 2. The underlined sentence" You don't get it,and you never will" in the 4th paragraph implies that .
A. the teenagers don't want to admit their weakness
B. the teenagers think that their parents will never understand them
C. the parents do not necessarily force into the world of their children
D. the generation gap cannot be shortened despite their parents' efforts
( ) 3. It can be inferred from the last paragraphs that .
A. teenagers should guard their privacy
B. Nancy totally agrees with the two girls' opinions
C. parents are more concerned about children's safety
D. the two girls have obtained numerous support from the public
( ) 4. According to the two girls,teenagers nowadays are .
A. independent B. intelligent C. sensitive D. inconsiderate
