1、20 23年高考英语复习一一高三英语阅读理解专项练习（七）AA new test for COVID-19 is coming to store shelves throughout the U.S.This is the first test for thedisease that you can do at home.It does not need a prescription,or doctors approval,to use.Currently,the U.S.is testing nearly 2 million people daily,and most health expe
2、rts agree thecountry needs to be testing many more people than that.Most tests still require a nasal swab（鼻拭子）performed by a health professional,followed by processing at a laboratory.That typicallymeans you have to wait days for the test results.For months,health experts have stressed the need for
3、fast,widespread home testing,which allowspeople to screen themselves and avoid contact with others if they have an infection.With this newhome test,people can“swab their nose,run the test and find out their results in as little as 20minutes/said FDA commissioner Stephen Hahn.The test kit includes a
4、small tool to help you to take nasal swab,or sample from inside your nose.Once you swab your nostril（鼻孑L）you place the swab onto a small cartridge.This cartridgeanalyzes the sample and sends the results to an app on your smartphone.The app displays theresults and then helps you interpret them.Users
5、can also connect with a health professionalthrough the app.Ellumes test works differently than other tests.Most tests look for the genetic material of the virus.This is the material that hakes up its genes,which influence how the virus looks and acts.However,Ellumes test looks for proteins that the
6、virus sheds（散发）.These viral proteins are large moleculesthat can trigger a response from your immune system,which is the collection of cells and theirresponses that help the body fight off infections.Like other COVID-19 tests that look for proteins,日lumes test still has a shall chance of errors.FDAo
7、fficials say that people who get a negative result but still have coronavirus symptoms shouldfollow up with a doctor.Although the price of the test could prevent some people from using it,Dr.Michael Mina,aprofessor at Harvard University in Cambridge,Massachusetts,called the new test a great addition

13、ers were in his Haida Gwaii homeland.Thecommunity generally lives off the sea and makes dugout canoes and houses from local red cedars.Their numbers were ravaged by smallpox and other diseases in the 19h century.A formerpopulation of tens of thousands has declined to a few thousand today.The few Hai
14、da speakers are extremely concerned about the languages future and were veryenthusiastic about the film.More than 70 local people worked on the production,with Haidaspeakers taking incidental roles,weavers creating the costumes and other craftspeople makingprops.The film,set on Haida Gwaii in the 19
15、th century,is based on an old Haida myth about a man whosurvives an accident at sea,only to become so weakened that he is taken over by supernaturalbeings.It is part of a wider push to preserve the Haida language,including a new dictionary and recordingsof local voices.Mark Turin,associate professor
16、 at the University of British Columbia,said that Haida is amonglanguages that have been“pushed almost to the edge“and that,while numerous indigenouscommunities worldwide are trying to revive（复 舌）their language,the Haida people have taken anunusual approach.This film has done something that I dont th

20、compressing（压缩）it several hundred times.Transforming itinto liquid state is another option,but one that requires cooling the stuff to-2530.Either processrequires rugged tanks.Over time,hydrogen gas can pass slowly into metals,weakening them andpotentially causing cracks.Tanks must be built from spec
21、ial materials designed to resist thisbreakdown.Researchers at the Fraunhofer Institute led by Marcus Vogt,think that supplying hydrogen as goop（糊状）offers a way around some of its limitations.They have been experimenting with a chemicalcompound that can be pumped into a container and then persuaded t
22、o give off its hydrogen ondemand.Their invention which they nickname“powerpaste”,looks like toothpaste.Its main ingredient ismagnesium hydride,a compound that when introduced to water;reacts with it to form hydrogenand magnesium hydroxide.The escaped hydrogen can then be redirected into a fuel cell,
23、where itreacts with oxygen from the air to generate electric power.The magnesium hydroxide waste isemptied from the reactor automatically.Dr Vogts scheme offers several advantages over batteries,petrol and more conventional ways ofhandling hydrogen.One is the storage of energy than either batteries
24、or petrol can manage.Asecond is ease of refilling,which is simply a matter of swapping an empty container of paste for afull one,and topping up the water,which is stored in a separate tank.A third advantage is that,unlike a battery,the paste does not gradually lose its stored energy if it is left on
25、 the shelf.Moreover;the paste itself is harmless,as are the reactions by-products.But there are still more to work through.Magnesium hydride reacts only slowly with water.Toovercome this,Dr Vogt and his team have found a chemical additive that greatly accelerates thereaction.They have also found a w
