Its vision is that 13 2015, malaria “is no longer a major 14 of mortality and no longer a barrier 15 social and economic development“. The report 16 provides a healthy picture of th

UNICEF“s health chief Pater Salama is 19 and says the future looks bright. He reports: “With the strong backing of some of the international donors and

17、the 20 of ACTs starting to be reduced, I think governments are becoming more confident now that this will be a sustainable strategy for anti-malaria treatment.“（分数：20.00）六、Section Reading Co(总题数：0，分数：0.00)七、Part A(总题数：0，分数：0.00)八、Text 1(总题数：1，分数：5.00)Computer microchips could become smaller, faster

18、and cheaper, thanks to scientists in the United States who have developed a speedier method of printing minuscule patterns on silicon chips. The discovery, by Stephen Chou and fellow scientists at Princeton University in New Jersey, could allow electronics manufacturers to increase the density of tr

19、ansistors on silicon chips by 100- fold and streamline production at the same time. Instead of taking 10 or 20 minutes to make a computer chip, the electrical engineers have imprinted features measuring I0 nanometers, or 10 millionths of a millimeter, on a computer chip in a quarter of a millionth o

20、f a second. The achievement, which could pave the way for more powerful computers and memory chips, is reported in the science journal Nature. “You just imprint the pattern directly into the silicon. You not only reduce the steps, you can do it in nanoseconds,“ Chou said in a statement. Silicon chip

21、s are minute slices of semiconducting material made to carry out functions in everything from toasters and mobile phones to giant corporate computers. Scientists had been looking for a replacement for silicon because they thought it would be impossible to improve the silicon chip, which would limit

22、advancements in chip size and speed. Chou has done away with etching, the normal way to make small patterns in silicon, and pressed a mould against a piece of silicon and applied a laser pulse for just 20 billionths of a second. It melts and resolidifies around mould. “Here we do not need to use all

23、 those steps,“ Chou said. “Scientifically, people are still trying to understand how it works, because it is amazing that it works at all.“ He calls the method Laser-Assisted Direct Imprint or LADI. Princeton University is applying for a patent on the technique. In a commentary on the research in Na

24、ture, Fabian Pease, of Stanford University, said the achievement will allow electronics manufacturers to continue the pace of miniaturization and keep Moore“s laws on track. Moore“s Law, observed by Intel Corp, co-founder Gordon Moore in 196.5, posits that the number of transistors on a semiconducto

25、r doubles roughly every 18 months. “A new imprinting technology for the production of silicon chips, introduced by Chou et al, could keep us on track,“ Pease said, adding that the law could hold for possibly another two decades.（分数：5.00）(1).What is the significance of the new technology?（分数：1.00）A.I

The main problem, of

41、course, lies in air. How could air be supplied to swimmers below the surface of the sea? Pictures made about 2,900 years ago in Asia show men swimming under the surface with air bags tied to their bodies. A pipe from the bag carried air into the swimmer“s mouth. But little progress was achieved in t

42、he invention of diving devices until about 1490, when the famous Italian painter, Leonardo da Vinci, designed a complete diving suit. In 1680, an Italian professor invented a large air bag. with a glass window to be worn over the diver“s head. To “clean“ the air a breathing pipe went from the air ba

43、g, through another bag to remove moisture, and then again to the large air bag. The plan did not work, but it gave later inventors the idea of moving air around in diving devices. In 1819, a German, Augustus Siebe, developed a way of forcing air into the head-covering by a machine operated above the

44、 water. Finally, in 1837, he invented the “hard-hat suit“ which was to be used for nearly a century. It had a metal covering for the head and an air pipe attached to a machine above the water. It also had small openings to remove unwanted air. But there were two dangers to the diver inside the “hard

45、-hat suit“. One was the sudden rise to the surface, caused by a too great supply of air. The other was the crushing of the body, caused by a sudden diving into deep water. The sudden rise to the surface could kill the diver; a sudden dive could force his body up into the helmet, which could also res

46、ult in death. Gradually the “hard-hat suit“ was improved so that the diver could be given a constant supply of air. The diver could then move around under the ocean without worrying about the air supply. During the 1940s diving underwater without a special suit became popular. Instead, divers used a

47、 breathing device and a small covering made of rubber and glass over parts of the face. To improve the swimmer“s speed another new invention was used: a piece of rubber shaped like a giant foot, which was attached to each of the diver“s own feet. The manufacture of rubber breathing pipes made it pos

48、sible for divers to float on the surface of the water, observing the marine life underneath them. A special rubber suit enabled them to stay in cold water for long periods, collecting specimens of animal and vegetable life that had never been obtained in the past. The most important advance, however

49、, was the invention of a self-contained underwater breathing apparatus, which is called a “scuba“. Invented by two Frenchmen, Jacques Cousteau and Emile Gagnan, the scuba consists of a mouthpiece joined to one or two tanks of compressed air which are attached to the diver“s back. The scuba makes it possible for a diver-scientist to work 200 feet underwater or even deeper for several hours. As a result, scientists can now move around freely at great depths, learning about the wonders of the sea.（分数：4.00）(1).During the period 14901979
