select one word for each blankfrom a list of choices given in a word bank following the passage.Read the passage through carefully beforemaking your choices.Each choice in the bank is identified by a letter.Please mark the corresponding letter foreach item on Answer Sheet 2 with a single line through the centre.You may not use any of the words in the bankmore than once.According to psychologist Sharon Draper,our clothing choices can absolutely affect our wellbeing.When we wear ill-fitting clothes,or feel over-or under-dressed for an event,it's natural to feel self-conscious or even stressed.Conversely,she says,opting for clothes that fit well and26 with your senseof style can improve your confi dence.But can you improve your health through your 27 clothing,without having to dash out and buy a wholenew 28?"Absolutely,"says Draper.If your goal is to improve your thinking,she recommends picking clothesthat fi t well and are unlikely to encourage restlessness,so,avoid bows,ties and unnecessary29.It also helpsto opt for clothes you 30as tying in with your goals,so,if you want to perform better at work,select piecesyou view as professional.Draper says this fi ts in with the concept of behavioral activation,whereby 31 in abehavior (in this case,selecting clothes)can set you on the path to then achieving your goals (working harder).rut (if we wear the same clothes-even if they're our favorites-thus opting for an item you don'twear often,or adding something different to an outfit,such as a hat,can 33 shift your mood.On dayswhen you're really 34 to brave the world,Draper suggests selecting sentimental items of clothing,suchas ones you wore on a special day,or given to you by a loved one,as clothes with35 associations canhelp you tap into constructive

are going to read a passage with ten statements attached to it.Each statementcontains information given in one of the paragraphs.Identify the paragraph from which the information isderived.You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer thequestions by marking the corresponding letter on Answer Sheet 2.Do music lessons really make children smarter?A)A recent analysis found that most research mischaracterizes the relationship between music and skillsenhancement.B)In 2004,a paper appeared in the journal Psychological Science,titled "Music Lessons Enhance IQ."Theauthor,composer and psychologist Glenn Schellenberg,had conducted an experiment with 144 childrenrandomly assigned to four groups:one learned the keyboard for a year,one took singing lessons,one joinedan acting class,and a control group had no extracurricular training.The IQ of the children in the two musicalgroups rose by an average of seven points in the course of a year;those in the other two groups gained anaverage of 4.3 points.C)Schellenberg had long been skeptical of the science supporting claims that music education enhanceschildren's abstract reasoning,math,or language skills.If children who play the piano are smarter,he says,itdoesn't necessarily mean they are smarter because they play the piano.It could be that the youngsters whoplay the piano also happen to be more ambitious or better at focusing on a task.Correlation,after all,does notprove causation.D)The 2004 paper was specifically designed to address those concerns.And as a passionate musician,Schellenberg was delighted when he turned up credible evidence that music has transfer effects on generalintelligence.But nearly a decade later,in 2013,the Education Endowment Foundation funded a bigger studywith more than 900 students.That study failed to confirm Schellenberg's findings,producing no evidence thatmusic lessons improved math and literacy skills.E)Schellenberg took that news in stride while continuing to cast a skeptical eye on the research in his field.Recently,he decided to formally investigate just how often his fellow researchers in psychology andneuroscience make what he believes are erroneous-or at least premature-causal connections betweenmusic and intelligence.His results,published in May,suggest that many of his peers do just that.F)For his recent study,Schellenberg asked two research assistants to look for correlational studies on the effectsof music education.They found a total of 114 papers published since 2000.To assess whether the authorsclaimed any causation,researchers then looked for telltale verbs in each paper's title and abstract,verbsIike“enhance,”“promote,.”“facilitate,”and“strengthen..”The papers were categorized as neuroscience ifthe study employed a brain imaging method like magnetic resonance,or if the study appeared in a journalthat had "brain,""neuroscience,"or a related term in its title.Otherwise the papers were categorized aspsychology.Schellenberg didn't tell his assistants what exactly he was trying to prove.G)After computing their assessments,Schellenberg concluded that the majority of the articles erroneouslyclaimed that music training had a causal effect.The overselling,he also found,was more prevalent amongneuroscience studies,three quarters of which mischaracterized a mere association between music training andskills enhancement as a cause-and-effect relationship.This may come as a surprise to some.Psychologistshave been battling charges that they don't do "real"science for some time-in large part because manyfindings from classic experiments have proved unreproducible.Neuroscientists,on the other hand,armedwith brain scans and EEGs(脑电图)，have not been subject to the same degree of critique.H)To argue for a cause-and-effect relationship,scientists must attempt to explain why and how a connectioncould occur.When it comes to transfer effects of music,scientists frequently point to brain plasticity-the factthat the brain changes according to how we use it.When a child learns to play the violin,for example,severalstudies have shown that the brain region responsible for the fine motor skills of the left hand's fingers is likelyto grow.And many experiments have shown that musical training improves certain hearing capabilities,likefiltering voices from background noise or distinguishing the difference between the consonants ()'b'andgD)But Schellenberg remains highly critical of how the concept of plasticity has been applied in his field."Plasticity has become an industry of its own,"he wrote in his May paper.Practice does change the brain,heallows,but what is questionable is the assertion that these changes affect other brain regions,such as thoseresponsible for spatial reasoning or math problems.J)Neuropsychologist Lutz Jancke agrees."Most of these studies don't allow for causal inferences,"he said.Forover two decades,Jancke has researched the effects of music lessons,and like Schellenberg,he believes thatthe only way to truly understand their effects is to run longitudinal studies.In such studies,researchers wouldneed to follow groups of children with and without music lessons over a long period of time-even if theassignments are not completely random.Then they could compare outcomes for each group.K)Some researchers are starting to do just that.The neuroscientist Peter Schneider from Heidelberg Universityin Germany,for example,has been following a group of children for ten years now.Some of them werehanded musical instruments and given lessons through a school-based program in the Ruhr region ofGermany called Jedem Kind ein Instrument,or"an instrument for every child,"which was carried out withgovemment funding.Among these children,Schneider has found that those who were enthusiastic aboutmusic and who practiced voluntarily showed improvements in hearing ability,as well as in more generalcompetencies,such as the ability to concentrate.L)To establish whether effects such as improved concentration are caused by music participation itself,andnot by investing time in an extracurricular activity of any kind,Assal Habibi,a psychology professor at the
