In a research lab in New Jersey. U.S, 16-year-old Alon Millet carefully squeezes out a special solution(溶液)onto some mung beans(绿豆)drop by drop, trying to help fight world hunger.
Last year, the teenager was one of the four students who received a $10,000 award from the US Agency for International development—chosen from 1,700 high schools in more than 70 countries. Millet’s experiments “could change the way plants are grown in the developing world”, protecting them against drought and natural disasters, said Courtney Mason, a program manager at the agency.
Three years ago, Millet’s father told him that an Israeli company had used a protein solution to make trees grow larger. And that, in tum., helped to produce more paper with fewer trees. “So I started thinking, ‘what else could this be used for?’” said Millet. He chose mung bean, an important crop in the developing world, which provides a good amount of protein and grows quickly. Then he contacted the company, FuturaGene, whose scientist agreed to share the solution.
He started experimenting. Could the beans grow larger and survive in tough environments? After three years of repeatedly putting the seeds into the solution, measuring, testing and examining, “some pretty good things happened, ”he said.
Donna Leonardi, his adviser, said she “sees a mature researcher in him, who sees the ‘big picture’ in what his research could do for people. And he’s not afraid to fail. He sees problems as challenges. ”
Millet is now on his 26th experiment with his mung beans, continuing his search for a better understanding of how the solution is changing the bean. 24. Paragraph 3 mainly tells us . A. the influence of Millet’s father on him B. the generosity of the company, FuturaGene C. what inspired his interest in the research D. why he chose mung beans for his research
25. How did the solution change the mung beans in Miller’s experiments? A. It made the beans grow faster. B. It prevented the beans from falling ill.
C. It helped the beans fight against hard environments. D. It improved the genes of the beans.
26. Millet sees ‘big picture’ in his research. He probably A. sees his bright future as a researcher B. finds the potential value of his research C. fears the hardships in his experiments D. predicts what the mung beans will be like
27. Which of the following words best describe Millet? A. Curious and ambitious. B. Talented and efficient. C. Hardworking and polite. D. Imaginative and humorous.
C
People have different ways of dealing with a common cold. Some take medicines such as aspirin (阿司匹林)while others try popular home remedies (疗法) like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing rally cures it. So why do people sometimes believe their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it’s easy to believe that it’s medicine rather than time that deserves the credit, USA Today reported.
Recently, scientists came closer to figuring out why we are powerless against a cold. To understand it, you first need to know how antiviral (抗病毒的) drugs work. They attack the virus by attaching to and changing the surface structures of the virus. Meanwhile, the drug must fit and lock into the virus like the right piece of a jigsaw (拼图) puzzle, which means scientists have to identify the virus and build a 3-D model to study its surface before they can design an antiviral drug. The two cold viruses known to scientists were rhinovirus A and B. But they didn’t find out the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the
common cold, but drugs that work well against rhinovirus A and B have little effect when used against C.
“This explains most of the previous failures of drug trials against rhinovirus, ” Professor Ann at University of Wisconsin, US told Science Daily.
Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly-detailed (高清的) 3-D model of the virus, with which in hand, hopefully a real cure for common cold is on its way. Soon we may no longer have to waste our money on medicines that don’t really work.
28. The author wants to tell us in the reading. A. different ways to deal with a common cold B. why nothing cures a common cold C. how we cure a common cold D. different causes of a common cold
39. What does the underlined word “this”refer to?
A. The reason why scientist haven’t defeated all the viruses. B. The reason why scientists haven’t built a model of the rthinovirus.. C. The fact that all drugs have great effect on the three rthinovirus. D. The fact that not all drugs work well against the three rhinovirus. 30. What’s the benefit of building 3-D model of the virus ? A. It makes a cure for common cold possible. B. It helps to identify the virus. C. It changes the surface of the virus. D. It shows the work of medicines.
