7、7.00)Most Adults in U.S. Have Low Risk of Heart DiseaseMore than 80 percent of U.S. adults have a less than 10-percent risk of developing heart disease in the next 10 years, according to a report in the Journal of the American College of Cardiology. Just 3 percent have a risk that exceeds 20 percent

8、.“I hope that these numbers will give physicians, researchers, health policy analysts, and others a better idea of how coronary heart disease is distributed in the U.S. population,“ lead author Dr. Earl S. Ford, from the Centers for Disease Control and Prevention in Atlanta, said in a statement.The

9、findings are based on analysis of data from 13,769 subjects, between 20 and 79 years of age, who participated in the Third National Health and Nutrition Examination Survey from 1988 to 1994.Overall, 82 percent of adults had a risk of less than 10 percent, 15 percent had a risk that fell between 10 t

10、o 20 percent, and 3 percent had a risk above 20 percent.The proportion of subjects in the highest risk group increased with advancing age, and men were more likely than women to be in this group. By contrast, race or ethnicity had little effect on risk distributions.Although the report suggests that

11、 most adults have a low 10-year risk of heart disease, a large proportion have a high or immediate risk, Dr. Daniel S. Berman, from Cedars-Sinai Medical Center in Los Angeles, and Dr. Nathan D. Wong, from the University of California at Irvine, note in a related editorial.Aggressive treatment measur

And you dont hav

16、e to lug a hand held device along with you for it to work.Logitechs technology works like this: The pen writes normally, using normal ballpoint pen ink. But while you are writing, a tiny camera inside the pen is also taking 100 snapshots per second of what you are doing, mapping your writing via a p

17、atchwork of minute dots printed on the paper. All this information the movement of your pen on the paper, basicallyis then stored digitally inside the pen, whether you are writing notes or drawing complex diagrams. You can store up to 40 pages worth of doodles in the pens memory. As far as you are c

18、oncerned, you are just using a normal pen.It is only when you drop the pen into its PC-connected cradle that the fun begins. Special software on your PC will figure out what you have done, and begin to download any documents you have written since the last time it was there. Depending on whether you

19、 have ticked certain boxes on the special notepad, it can also tell whether the document is destined to be an e-mail, a “to do“ task, or a diagram to be inserted into a word-processing document. Once the documents are downloaded you can view them, print them out or convert them to other formats.The

20、io Personal Digital Pen is a neat and simple solution to the problem of storing, sharing and retrieving handwritten notes, as well as for handling diagrams, pictures and other non-text doodling.

The pen is light and works like a normal pen if you need it to, while the special notepads look and feel l

22、ike notepads. The only strange looks will be from people who are curious why you are writing with a cigar.The io Personal Digital Pen also has potential elsewhere. FedEx, for example, is introducing a version of the pen so that customers can fill out forms by handinstead of punching letters into cum

23、bersome devices. Once that data is digital more or less anything can be done with ittransferring it wirelessly to a central computer, for example, or via a hand-phone. Doctors could transmit their prescriptions directly to pharmacies, reducing fraud; policemen could send their reports back to the st

28、 a glass of water. You can solve the problem by activating the saliva in you mouth. First gently bite the edges of your tongue with your teeth. Or, press your entire tongue to the bottom of your mouth and hold it there until the saliva flow. Or you can imagine that you are slicing a big juicy lemon

29、and sucking the juice.Before you begin your talk, be kind to your voice. Avoid milk or creamy drinks which coat your throat. Keen your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that you are losing your voice, stop talking completely. Save your voice for y

30、our speech. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If you need to see a doctor, perhaps you can get some advice from a professional singer. In the meantime, do not even talk in a low voice.What about drinking alcohol to wet your throat?

31、I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work

32、together properly. Save the alcohol until you finish speaking.Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a lifetime. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said, “We learn to skate in the summer and swim

33、 in the winter.“ Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body.（分数：15.00）(1).All the following are mentioned in the passage a

38、3.00）A.B.C.D.六、B第二篇/B(总题数：1，分数：15.00)Plant GasScientists have been studying natural sources of methane for decades but hadnt regarded plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. Now Keppler and his colleagues find th

39、at plants, from grasses to trees, may also be sources of the greenhouse gas. This is really surprising, because most scientists assumed that methane production requires an oxygen-free environment.Previously, researchers had thought that it was impossible for plants to make significant amounts of the

40、 gas. They had assumed that, microbes need to be in environments without oxygen to produce methane. Methane is a greenhouse gas, like carbon dioxide. Gases such as methane and carbon dioxide trap heat in Earths atmosphere and contribute to global warming.In its experiments, Kepplers team used sealed

41、 chambers that contained the same concentration of oxygen that Earths atmosphere has. They measured the amounts of methane that were released by both living plants; and dried plant material, such as fallen leaves.With the dried plants, the researchers took measurement at temperatures ranging from 30

42、 degrees Celsius to 70 degrees Celsius. At 30 degrees Celsius, they found, a gram of dried plant material released up to 3 nanograms of methane per hour. (One nanogram is a billionth of a gram.) With every 10-degree rise in temperature, the amount of methane released each hour roughly doubled.Living

43、 plants growing at their normal temperatures released as much as 370 nanograms of methane per gram of plant tissue per hour. Methane emissions tripled when living and dead plant was exposed to sunlight.Because there was plenty of oxygen available, its unlikely that the types of bacteria that normall

44、y make methane were involved. Experiments on plants that were grown in water rather than soil also resulted in methane emissions. Thats another strong sign that the gas came from the plants and not soil microbes.The new finding is an “interesting observation,“ says Jennifer Y. King, a biogeochemist

45、at the University of Minnesota in St. Paul. Because some types of soil microbes consume methane, they may prevent plant-produced methane from reaching the atmosphere. Field tests will be needed to assess the plants influence, she notes.（分数：15.00）(1).What was scientists, understanding of methane? A.I

46、t was produced from plants. B.It was not a greenhouse gas. C.It was produced in oxygen-free environments. D.It traps more heat than any other greenhouse gas.（分数：3.00）A.B.C.D.(2).To test whether plants are a source of methane, the scientists created _. A.a oxygen-free environment B.an environment wit

47、h the same concentration of oxygen as the Earth has C.a carbon dioxide-free environment D.an environment filled with the greenhouse gas（分数：3.00）A.B.C.D.(3).Which statement is true of the methane emissions of plants in the experiment? A.The lower the temperature, the higher the amount of methane emissions. B.Living plants release less methane than dried plants at the same temperature. C.When exposed to sunlight, plants stop releasing methane. D.The higher the temperature, the greater the amount of methane emissions.（分数：3.00）A.B.C.D.(4).Which of the following about methane is
