有国界,科学第正是因为中国精神31.What message does the author want to convey in the last paragraph?中国精神A.Kids should have higher expectations for a phone's use.中国精神B.Parents should inform their kids they should use phones properly.我有国士支撑起社会的C.Kids should follow the rules in case they lose or damage their phones.他们是国D.Parents should guide their kids on how to power a phone up for the first time中国精神D在两年前University of Minnesota Twin Cities College of Seience and Engineering researchers have invented a cheaper,中国精裤sferand simpler technology that will allow a"stubborgroup of metals and metal oxides to be made int thinim中国精剂中国精利used in many electronics,computer components,and other applications.The researchers applied for a patent for the中国精剂technology and have already gained interest from industry.半个多世Many metals and their compounds must be made into thin films before they can be used in technological products走过那身like electronics."Stubborn"metals are very difficult to convert into thin films because they require extremely high还记得争在徐秀temperatures (usually more than 2,000 degrees Celsius)to evaporate().Typically,scientists combine these出来,年仅,metal films using techniques like sputtering and electron beam evaporation(溅射和电子束蒸发).The latter consists如今,of melting and evaporating metals at high temperatures and allowing a film to form on the top.But,this conventional徐家三代人,一个人method is very expensive,uses a lot of energy,and may also be unsafe due to the high voltage used.女排、塞罕Now,University of Minnesota researchers have developed a way to evaporate these metals at significantly lower里!temperatures,fewer than 200 degrees Celsius instead of several thousands.By designing and adding organic ligands-中国灌combinations of carbon,hydrogen,and oxygen atoms-to the metals,the researchers were able to substantially保安李真正的increase the materials'vapor pressures,making them easier to evaporate at lower temperatures.Not only is their new出现时,他technique simpler,but it also makes higher quality materials that are easily expanding.正如鲁"The ability to make new materials with ease and control is essential to transition into a new era of energy是等于为帝economy,"said Bharat Jalan,the senior author of the study."There is already a historical link between the把中国史,赋innovation()in synthesis science and the development of new technology.Millions of dollars go into makingmaterials for various applications.Now,we've come up with a simpler and cheaper technology that enables better评之三:materials with atomic accuracy."These metals are used to make many products,from semiconductors for computer applications to display奋斗月“当technology.We hope to see renewed interest in the more complex materials which contain these stubborn metals.学芳察用32.What does the author mean by saying "stubborn"metals?oAiosus s.A.The metals are complex to use.的停修号身B.It is expensive to patent the metals山n山b的的,,色对g相T的C.It is dangerous to create the metalsD.The metals are hard to be made into thin filmsi量or/eh1袖33.How does researchers increase the vapor pressures?不的量,德她的o你商图A.They increase the voltage while sputtering.山位的0恤海底。B.They raise the temperature to 2,000 degrees Celsius.英语卷(五)试题第6页(共10页)
