全国©0所名校高三单元测试示范卷札记Even after accounting for things like a person's age,gender,socioeconomic status,and chronichealth conditions,there was a significant difference between the two groups."American adults whoexperience high levels of positive emotions,such as feeling 'cheerful'and 'extremely happy',aremore likely to have healthy blood-lipid (analysis,"explains lead study author Jiah Yoo,butthe same was not true among Japanese adults.Yoo explains,"In East Asian cultures,people com-monly view positive emotions as having dark sides-they may attract unnecessary attention fromothers,and can be a distraction from focusing on important tasks.Past research has reached similar conclusions.In a 2015 Stanford study of 690 Chinese andAmerican participants,for example,the Americans generally sought to maximize positive feelingsand minimize negative ones,while the Chinese subjects were more likely to report that they com-monly felt mixed emotions.It's comforting for me to hear that at least one culture may accept and embrace my gloominess.I need to be gentler with myself.Maybe I don't need to shoot for delight.Maybe satisfaction canfeel just as good.32.Which country does the author probably come from?A.America.B.Britain.C.Japan.D.China.33.What does paragraph 4 mainly intend to tell us?A.American adults are healthier than Japanese ones.B.One's health is involved with many factors.C.Culture plays a role in one's attitude towards positive emotions.D.Health is linked with happiness.34.What can we know from the text?A.Never label yourself a pessimist.B.Optimists don't always live longer.C.Positive emotions are essential to culture.D.Optimists are better at adapting to society.35.Where is the text probably from?A.A tourist guide.B.A story book.C.A science magazine.D.A technology report.【答案与解析】文化影响了对乐观的认识。32.A根据第1段第4句及下文可知，作者最有可能来自美国，其文化强调乐观的价值。33.C本段主要研究美国人和日本人对乐观的认识，由此表明，不同的文化可能确实会影响人们对乐观的认识。34.B根据全文可知，作者通过比较证实了在某些文化背景下，乐观确实让人长寿，但并非都是如此。35.C研究表明，文化背景不同，人们对乐观的认识也不同，故本文可能来自科学杂志。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 sum-mer day?Long story shortyes.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 different 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.One study from the Human Kinetics found that a 10-minute cold shower immediately after an exercise session can assist with hydration status.39 Meanwhile,they will feel less tired,too.32【24G3DY(新高考)·英语-R-必考-Y】
