题目内容
Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more food.
In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops.
Wamugu went to war against the virus. Her search for a way to save the sweet potatoes led to a lab in St.Louis, Missouri.
The lab mainly works on genes, the chemical “computer programs” found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering.
Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes.
That’s just the beginning, Wambugu believes. Genetically modified foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry.
41. The text is written mainly to _________
A. tell us sweet potatoes are in danger of being attacked by virus
B. introduce Wambugu’s contribution to genetic engineering
C.introduce a new way of killing plant viruses
D. tell how hard Wambugu worked in her lab for three years

A. Her wish to save sweet potatoes in Kenya.
B. Her great interest in genetic engineering.
C. Her love for sweet potatoes.
D. Her interest in plant life.
43. The fourth paragraph mainly explains what _________is.
A. a crop virus B. chemical technology
C. a computer program D. genetic engineering
44. What is Wambugu’s attitude toward “genetic engineering”?
A. It will help more hungry people.
B. It should be carefully used.
C. It has more disadvantages than advantages.
D. It is a too expensive technology at present.
45. According to the passage, which of the following is NOT true?
A. Florence Wambugu often helps farmers with their work.
B. Florence Wambugu has studied sweet potatoes for 10 years.
C. Genes can be moved from one thing to another.

The hole in the earth's protective ozone layer（臭氧层）won't repair itself until about two decades later than had been expected, scientists announced.
The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation（紫外线辐射）, helping to make life on Earth possible. For many dacades, ozone was depleted（削减） by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere.
Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere（平流层）over the past 27 years.
The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed.
Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate（估计）ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area.
Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065.
1.According to the passage, the ozone layer _______
|
A．absorbs as much as sunlight as possible |
|
B．protects man against ultraviolet radiation |

C．controls the changes in temperature |

|
A．it was once proved by facts |
|
B．it has been studied for 27 years |
|
C．it was created by many scientists |

D．it is related to satellites and airplanes |
3.The underlined word “they” in the fifth paragraph refers to ________
|
A．the levels of ozone |

B．ozone-depleting gases |

C．the ozone holes |

D．the areas far from the poles |
You Mi, a lovely and confident 17-year-old student, is the first Chinese high school student to appear on the cover of the popular young adults’ fashion magazine Seventeen.
“You is IN,” said Wang Lihua，Editor-in-Chief of Seventeen. “She is active and mature (成熟) because of her knowledge on everything from academic studies，to books on art，to movies. We find she’s the very style we’re looking for to represent young people’s attitudes.”
You also impressed Wang with her fluent English when they first met last year. As the hostess of an English broadcasting program at the High School Affiliated to Renmin University（人大附中）， You is always praised for speaking English almost like a native speaker. “I’ve built up my English by watching thousands of English DVDs since I was 10,” she explained.
But for You，watching isn’t enough. Last year，while in Senior 1， she met a talented (有才能的) boy who showed self-made DV movies at the English Corner in her school.
“I thought it was so cool and I knew that I should start making my own films，” she said. So she wrote a campus (校园) story, persuaded schoolmates to star in it and then began shooting a 30-minute DV movie，all in English. “I played one of the leading roles，actually I was everything in my film. I worked on it every day during the holidays,” she recalled. The movie finally became a big hit on campus，earning You a strong reputation（名气） as a DV movie director.
But this is not the only field she wants to master. Though a science student, You likes art, literature and fashion design very much.
“There are people who can be artists，there are people who edit books, and there are people who become film producers. But I just hope to mix all the things up!” she said. “There is an old saying I believe：Chances favor only the prepared mind.”
