The researchers grew rice plants in a c

2、ontrolled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be

3、 most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an

4、 effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions.Howeve

5、r,vitamin E levels increased by about 13 percent on average.The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyos Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indon

6、esia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern i

7、s there are many more surprises to come,” he said.Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depe

8、nd on over millions of years without having effects come back to affect our own health.The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.32. Which

9、 county would be influenced most by planet-warming gases according to the text?A. ChinaB. MyanmarC. AmericaD. Britain33. How is Paragraph 3 mainly developed?A. By comparison.B. By giving examples.C. By analyzing causes.D. By describing a process.34. What does the underlined sentence in Paragraph 5 m

Climate change will cause more unexpected problems.35. Which of the following statements is true according to the text?A. Myerssaid we could change

11、all the natural systems for the sake of our health.B. The poorest people in all the least developed countries would be influenced most.C. The researchers grew 18 kinds of rice in China and Japan in a controlled environment.D. Protein in rice grown under high carbon dioxide conditions is increased by

12、 10 percent.BADC（二）Plants are boring. They just sit there (光合作用)while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant co-evolution(协同进化)started with ants feeding on plants and plants evolving

13、ant-friendly features.Plants make a number of different structures that are specific for ant use. Some plants have evolved features that persuade ants into defending them from attack from other insects and even mmml. h nlud hollow thorns that nt will live nd, or tra ntr (琼浆) n lv or stems for the an

14、ts to eat. Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds. The ant will pick up the seed and

15、 carry it away, eat the food packet, and leave the seed - often in a nutrient-rich area where itll grow better, and since its farther away from its parent, they wont have to compete for resources.But scientists werent sure how the evolutionary relationship between ants and plants got started. If evo

16、lution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chicken-and-egg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving

17、structures to take advantage of ants.The history of ants and plants evolving together goes back to the time of the dinosaurs, and its not easy to tell from fossils who fired the first shot. However, it is a question of little significance. Scientists say their study maters because it provides a look

18、 at how these widespread and complex interactions evolved.32Some plants attach food packets to their seeds in order to.Areward the antsBget the seeds moved aroundCmake a fool of ants Dprovide nutrition for the seeds 33What does Paragraph 2 mainly tell us?AHow plants and ants interact.BWhat ants do t

DTo criticize peoples traditional views about plants.BACB（三）An experimental cleanup device calle

21、d RemoveDEBRIS has successfully casta net around a dummy (仿真的) satellite, imitating a technique that could one day collect spaceborne garbage.The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it s

22、ymbolizes an early step toward solving what has already been a critical issue: junk in space.Millions of pieces of junk are turning around in orbit, the result of 50 years of spacetravel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite c

The RemoveDEBRIS experiment is run by a company and researchers led by the U. K.s Surrey Space Center and includes Airbus,Airbus-owned Surrey Satellite Techn

24、ology Ltd. and FrancesArianeGroup.Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, inc

25、luding dead satellites up to 10 meters long.The RemoveDEBRIS satellite will conduct a few more experiments in the coming months, including testing navigation features that could help guide the satellite to a specific piece of debris.Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Cen

26、ter for Astrophysics, said the successof this weeks experiment was exciting, but he cautioned against“over- publicizing” it.There are still enormous barriers to clear before operational cleanup tasks are underway, he said, and the most discouraging is figuring out how to fund such projects.Aglietti,

27、 the Surrey professor who helped lead the RemoveDEBRIS project, said “The challenge will lie in persuading the relevant authorities to sponsor these tasks.”Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.3

There are no borders in me

Its a language of peace, and of development and progress.” Chen recalled the cooperation with the two French researchers for over 30 years.This years Sjoberg winners have developed a new and targeted treatment for a specific form of blood canc

39、our responsibilities at work andhome. In practice, itrarely happens, though. For some, thats because deep down they feet they dontdeserve it. For others, its simply that busy life makes it seem impossible to press pause. Either way,making sure you actually get a. moment to yourself requires a shift

40、in perspective. Dont wait until it feels right. Its unpleasant to have unfinished tasks bothering at your mind, soits tempting to tell yourself youll only relax once everything is under control. But since both workand family life generate an infinite number of to-dos, that strategy is doomed to fail
