DAre you a good judge of character?Can you make an accurate judgment of people's personalities based only onyour first impression of them?Ironically,the answer lies as much in them as it does in you.US psychologist Henry Adams tried to identify good judges of character in 1927.His research led him toconclude that people fell into two groups-good judges of themselves and good judges of others.Adams's researchhas been widely criticized since then,but he wasn't entirely wrong about there being two clearly different types.We need to define what a good judge of character is.Is it someone who can read personality or someone whocan read emotion?Those are two different skills.Emotions such as anger or joy or sadness can generate easilyidentifiable physical signs.Most of us would probably be able to accurately identify these signs,even in astranger.As such,most of us are probably good judges of emotion.In order to be a good judge of personality,however,there needs to be an interaction with the other person,andthat person needs to be a "good target"."Good targets"are people who show related and useful clues to theirpersonality.So this means "the good judge"will only appear when reading "good targets".This is according toRogers and Biesanz in their 2019 journal entitled "Reassessing the Good Judge of Personality"."We found clear andstrong evidence that the good judge does exist",Rogers and Biesanz concluded.But their key finding is that thegood judge does not have magical gifts of observation-they are simply able to"detect and use information providedby the good target”.So,are first impressions really accurate?Well,if you're a good judge talking to a "good target",then it seemsthe answer is"yes".And now we know that good judges probably do exist,more researches can be done into howthey read personality,what kind of people they are-and whether their skills can be taught.32.What is the conclusion of Adams's research?A.Fewer people can read physical signs.B.Most people are good judges of themselves.C.First impressions have a huge effect on people.D.There are two obviously different types of people.33.What can be learned from Paragraph 4?A.There is no need to interact with the other person.B.Good judges are related to good targets.C.Good judges have magical talents for emotion.D.Good targets are persons who hide important information.34.What is the author's attitude towards the research on good judges?A.Disapproving.B.Indifferent.C.Objective.D.Pessimistic.35.What is the author's purpose in writing the text?A.To inform readers of a good judge of character.B.To highlight the importance of good character.C.To introduce some ways of define good characters.D.To explain what first impressions are.第二节（共5小题；每小题2.5分，满分12.5分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。高二（上）期末联合检测试卷（英语）第5页共14页
