1、unit 2 working the land reading课时作业.阅读理解AWhen asked about her childhood in the documentary Alive Inside,a 90-year-old woman with dementia(痴呆) replies,“Ive forgotten so much.”Filmmaker Michael Rossato-Bennett then plays music from her past for her.“Thats Louis Armstrong,”she says.“Hes singing When th
2、e Saints Go Marching In and it takes me back to my school days.”She then recalls exact details from her life.Why does it happen?Music tends to accompany events that arouse emotions or otherwise make strong impressions on ussuch as weddings and graduations.These kinds of experiences form strong memor
3、ies,and the music and memories likely become intertwined(紧密相连) in our neural(神经的) networks,according to Julene Johnson,a professor at the University of California.Movements,such as dancing,also often pair with our experience of music,which can help form memories.Even many years later,hearing the mus
4、ic can bring back memories of these long-past events.As Alive Inside shows,music has this power even for many people with dementia.Researchers note that the brain areas that process and remember music are typically less damaged by dementia than other areas,and they think it may explain the phenomeno
5、n.They also pay attention to elderly people with dementia,especially those in nursing homes.“Its possible those long-term memories are still there,”Johnson says,“but people just have a harder time accessing them because theyre in a strange place and therere not a lot of circumstances in which someon
6、e could pull out those memories.”Johnson also notes that music is not universally useful for all people with dementia since there are some people with dementia whose brain area that recognizes music is damaged.Despite musics apparent benefits,few studies have explored its influence on memory recall
7、in people with dementia.“Its really an untapped area,”Johnson says.Petr Janata is one researcher investigating the topic of music and memory.He says that scientists still do not have the answers to why and how music reawakens memories in people with dementia,but this phenomenon is real and its just
8、a matter of time before its fully borne out by scientific research.1.What helps the old woman in Alive Inside recall her childhood?A.A film she has watched before.B.A song she has listened to before.C.The voice of her childhood friend.D.The description of her school days.2.What benefit of music is d
9、iscussed in Paragraph 2?A.It helps make lasting memories.B.It helps cure patients of dementia.C.It helps arouse emotions in special events.D.It helps remember dance movements easily.3.According to Johnson,what should we do for elderly people with dementia?A.Send them to nursing homes for good care.B
10、.Provide familiar environments for them.C.Play lots of classical music to them.D.Talk to them about their past.4.What do we know about the study into music and memory recall in people with dementia?A.It is criticized by Petr Janata.B.It is a ground-breaking study.C.It is supported by solid evidence.
11、D.It applies to all people with dementia.BEndless hours of piano practice can be the pain of a childs life,but there might be an added benefit of sticking to it.A study has found that learning a musical instrument as a child could keep you sharp at old age.The elderly who had piano,flute or other mu
12、sic lessons as a youngster did better on intelligence tests than others.And the longer they had played the instrument,the better they did.Dr Brenda Hanna said,“Musical activity throughout life may serve as a challenging cognitive(认知的) exercise,making your brain fitter and more capable of adapting to
13、 the challenges of ageing.”While much research has been done into how children benefit from music lessons,this is the first study to examine whether those effects can extend across a lifetime.A total of 70 healthy adults between 60 and 83 years old were divided into groups,depending on their musical
14、 experience.All of the musicians were amateurs,who had started playing an instrument at around 10 years old.Those who had played music longer were better on the tests,showing a clear link with the length of experience as well.However,high-level musicians who still played at an advanced age produced
15、similar results to the most skilled players who had given up.This indicated the duration of the musical study was more important than whether they continued playing in their older years.Dr Hanna said,“Based on previous research and our study results,we believe that both the years of musical particip
16、ation and the age of acquisition(习得) are critical.There are key periods in brain plasticity(可塑性) that enhance learning,which may make it easier to learn a musical instrument before a certain age,and thus may have a larger impact on brain development.”5.Whats the main idea of the text?A.Playing music is good for our health.B.Music is most important to young children.C.Playing music when young helps us st
