17、ning an instrument:how do pupils choose?All our teachers are highly qualified and experienced musicians,and pupils can learn to play a wide range of instruments,from the keyboard to the drums(鼓).We have open days when new pupils who are unsure which instrument to choose can come to the centre.They a

18、re able to speak to teachers about which instrument might be best for them,and they can also see and hear classes in action.Who is responsible for buying the instruments?Parents usually have to provide instruments.But parents of beginners are advised not to buy an instrument until they are told that

19、 a place is available.They should also find out from the teacher the most suitable type of instrument to get.When and where do lessons take place?Lessons are available in many schools,usually during the day.If there is no lesson available for a particular instrument in a particular school,other arra

20、ngements can be made at one of 6 our music centres for lessons on Saturday afternoons or weekday evenings.How are pupils taught?Pupils can learn in small groups,in classes or individually,depending on their needs.Small groups of three pupils have lessons that last thirty minutes.Class lessons last f

21、orty-five minutes and have at least ten pupils.Individual lessons are offered only to pupils who have some experience.Starting young:when can pupils begin?Children are never too young to become interested in music.We have special“Musical Youth”classes for children from the age of 3 to 8.These are de

22、signed to encourage young children to enjoy music through a variety of activities including singing,musical games,listening and movement.“Musical Youth”classes take place on Saturday mornings with groups of about 18 children.A parent or other adult must attend each session,and they are encouraged to

23、 sit with their children and help them with the activities.31.What can we learn from the passage?A.New pupils can see classes on an open day.B.Pupils can learn special instruments on Sundays.C.Parents must accompany pupils during the learning process.D.Teachers at the centre can provide the right in

24、struments for pupils.32.What is the best choice for children with some experience?A.Lessons for groups of ten.B.Individual lessons.C.Lessons for small groups of three.D.Special“Musical Youth”classes.33.The passage is intended for _.7 A.teachers B.parents C.musicians D.pupils B Nenad Sestan was worki

25、ng in his office one afternoon in 2016,when he heard his lab members whispering with excitement over a microscope.He realized something beyond their expectations was happening.The researchers,at Yale School of Medicine in New Haven,Connecticut,had found electrical activity in brains taken from dead

26、pigs.With that shocking result,Sestan realized what had started as a side project to find ways to better preserve brain tissue for research had changed into a discovery that could redefine our understanding of life and death.The excitement soon turned to concern,when the researchers thought they saw

27、 widespread,consistent electrical activity which can indicate consciousness(意识).Sestan brought in a neurologist,who determined the readout was actually an error,but the possibility had frightened them.Sestan kept his cool and immediately did two things:he shut down the experiment and contacted the U

28、S National Institutes of Health(NIH),as well as a Yale bioethicist(生物伦理学家).Over the next few months,experts discussed the potential ethical implications,such as whether the brains could become conscious and whether physicians needed to reconsider the definition of brain death.They submitted the work

29、 to Nature.But before the final paper was published,Sestan met sharp criticism from the press.Some even suggested that the researchers were engineering immortality(永生),or maintaining a room full of living brains in jars.Neither he nor his team wanted to discuss the results until the paper was out,bu

30、t as their inboxes filled with concerns and anger from animal rights activists and futurists,Sestan became depressed.He felt all they could do,however,was to hold off on correcting public misunderstandings until the expert review process had run its course.8 Since the paper was published in April,20

31、19,the team has been so busy fielding questions from the media and scientists that it hasnt performed any further experiments.Sestan wants to focus on his original questions and explore how long the brains can be maintained and whether the technology can preserve other organs.“We want to get outside

32、 opinion before we do anything,”Sestan says.“When you explore uncharted territory,you have to be extremely thoughtful.”34.What happened in the lab at Yale School of Medicine in 2016?A.A better method was found to maintain brain tissue.B.Researchers discovered how to redefine brain death.C.Brains fro

33、m dead pigs were accidentally discovered alive.D.Researchers arrived at the expected results of the experiment.35.Why did Nenad Sestan stop the experiment?A.He needed assistance with the final paper.B.He spotted a major mistake in the final result.C.He was frightened by the possibility of failure.D.

34、He was concerned about the related moral issues.36.What was peoples reaction towards Nenad Sestans experiment?A.The press were strongly opposed to the experiment.B.Some people supported the research on immortality.C.Nobody wanted to discuss the final result in advance.D.The public took a positive at

35、titude towards the experiment.9 37.How could we best describe Nenad Sestan?A.Responsible and reliable.B.Cooperative and creative.C.Determined and inspiring.D.Professional and cautious.C A butterflys wings can have many jobs besides keeping the insect high up in the air.They may be used to attract ma

36、tes,or to warn potential attackers to stay away.All of these roles,though,depend on their unchanging colouration.This plays into the idea that butterfly wings are dead tissue,like a birds feathers.In fact,thats not true.For example,in some species males wings have special cells releasing some chemic

37、als which attract females.Nanfang Yu,a physicist at Columbia University,in New York,has been looking into the matter.Together with Naomi Pierce,a butterfly specialist at Harvard University,he has now shown,in a paper published in Nature Communications in February,2020,that butterfly wings are,indeed

38、,very much alive.In their experiments,the two researchers used a laser(激光)to heat up spots on the wings of dozens of butterfly species.When the temperature of the area under the laser reached 40C or so,the insects responded within seconds by doing things that stopped their wings heating up further.T

39、hese actions included a butterfly turning around to minimize its profile to the laser,moving its wings up and down or simply walking away.Butterflies engaged in all of these heat-minimising activities even when the researchers blindfolded them.That suggested the relevant sensors were on the wings th

40、emselves.Dr Yu and Dr Pierce therefore searched those wings for likely looking sensory cells.They found some,in the form of neurons(神经元)that were similar to heat detectors known from other insects.They also uncovered disc-shaped cells that appeared to be similar to pressure-sensitive neurons.They gu

41、ess that these are there to detect deformation of the winginformation an 10 insect could use to control its flight pattern.The third discovery they made to contradict the“dead wing”idea was that some butterfly wings have a heartbeat.A butterflys wings have veins(静脉).These carry a bloodlike liquid wh

42、ich,researchers have now found in males,shows a pulse(脉搏)of several dozen beats per minute.The source of this pulse appears to be the scent(气味)pad,a dark spot on the wings that produces the female-attracting chemicals.Apparently,this“wing heart”acts as a pump that helps bloodlike liquid through the

43、scent pad.In all their experiments simulating different environmental conditions,Dr Yu and Dr Pierce consistently found that,different parts of the wing are covered by different sorts of scales(鳞屑).In particular,tubes pass through scales over the scent pads.This improves their ability to spread heat

44、 away and helps keep the living parts of a butterflys wings alive.38.A birds feathers are mentioned in Paragraph 1 to.A.introduce the latest research findings on a bird B.highlight the special feature of a birds feathers C.show common knowledge about butterfly wings D.stress the difference between a

45、 butterfly and a bird 39.What can we learn from Dr Yu and Dr Pierces experiments?A.Butterfly wings are complicated living organs.B.Butterfly wings have little reaction to external heat.C.The scent pads on some male butterfly wings are their hearts.D.Heat-minimising activities help detect deformation

46、 of the wings.11 40.What is the function of scales over the scent pads?A.Attracting mates.B.Increasing blood flow.C.Covering powerful tubes.D.Producing the cooling effect.41.Which of the following would be the best title for the passage?A.Seeing Is Believing B.More Than Meets The Eye C.Nothing Seek,

47、Nothing Find D.Fine Feathers Make Fine Birds D Fact or Fiction?Non-fiction can be broken down into many categories.One category is literary non-fiction,which is still based in fact but employs some of the storytelling elements that fiction uses.Literary non-fiction includes a type of autobiography(自

48、传)called memoir.Memoir most often focuses on a certain period of the authors life.It is,by definition,rooted in truth.Still,people sometimes question whether memoir should be categorized as non-fiction at all.As non-fiction,memoir is intended to be factual.Is this really the case,though,considering

49、memoir relies on human memory?One classic study,led by psychologist Elizabeth Loftus,showed how easily an interviewers choice of wording can influence an eyewitnesss account of a traffic accident.It is therefore reasonable to wonder whether memoir should continue to be branded as non-fiction.Certain

50、ly,human memory can be unreliable.However,a memoir author is undoubtedly writing about significant and impactful life events.Memories of such events are actually more reliable than others.Studies show that the more influential an event is,the more accurately 12 people recall the details.As an emotio
