全国@0所名校高三单元测试示范卷札记In one group of participants,some had first taken the initial mental exhaustion test.In another,some received magnetic pulses to upset activity in an area of the brain that previous research hadlinked to administrative control.In both groups,these interventions improved participants'perform-ance on the syllable task when they were unsure of their responses,indicating unconscious speechanalysis.(Confident responses suggest conscious recall instead.Georgetown University neuroscientist Michael Ullman,who was not involved in the study,likes thatit tested cognitive control differently."That's really good in science because you've got supportingevidence,"he says,adding that he would like to see higher language skills such as grammar studiedthis way.Ghent University psychologist Eleonore Smalle,who took part in the research,offers advicebased on her team's findings.When beginning to learn a language,she says,get yourself involved inits sounds,even-or especially-while distracted."Have a good glass of wine while listening to anews report in Italian,"she suggests with a laugh."Why not?It could help."32.What were the participants required to do in the study?A.Respond to familiar words.B.Read and hear four new words.C.Press keys to recognize the words.D.Try to avoid mistakes while writing.33.What is the finding of the study?A.Adults learn words much better than children.B.Cognitive fatigue is beneficial to grammar study.C.Tired learners perform better in language learning.D.Consciousness is vital to the study of new languages.34.What does Ullman think of the conclusion of the new study?A.Useful.B.Subjective.C.Ridiculous.D.Debatable.35.What does Smalle suggest?A.News is the best resource to learn a language.B.Italian wine enjoys a high level of popularity.C.Focus on a word's sound more than its meaning.D.Listen to a new language while doing something else.【答案与解析】研究发现不过度思考、减少思维参与有助于语言学。32.B根据第1段第1句可知,所有的参与者需要读、听新编的四个单词。33.C根据第2段倒数第2句可知,学者在疲劳时反而在学新语言中表现得更好。34.A根据第5段可知,Ullman认为该研究结论有实用价值。35.D通过最后一段可知,Smalle建议听外语时可以做其他事,这样效果更好。第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。People have a lot of opinions about drinking cold water.Some claim that drinking cold water isbad for your digestion.36 So what's the truth?Is it okay to enjoy a cup of cold water on a hot summer day?Long story short-yes.One major effect of drinking cold water is good for your hydration.37 And it helps keep your organs functioning properly.One study that reviewed six differ-ent male athletes that consumed water at different temperatures found that drinking water at 16 de-grees Celsius with a higher intake of water resulted in less sweating compared to the others.38Along with drinking it,cold water has been proven to also help athletes in workout recovery.32【24G3DY(新高考)·英语-R-必考-HEB】
