题目解答

答案

这道题目是一个阅读理解题,要求我们根据演讲者在公立学校教数学时的发现,选择正确的选项。题目没有直接提供原文,但根据选项内容和常见的教育类演讲主题(如卡罗尔·德韦克的“成长型思维”相关演讲),我们可以进行合理的推理。 我们逐个分析选项: A. 有些学生无法完成作业任务。 这个选项描述的是一个现象,但并不是一个“发现”的深层原因。很多老师都会遇到学生完不成作业的情况,这并不足以成为演讲者特别强调的“发现”。 B. 七年级的数学对大多数学生来说非常难。 这只是一个关于课程难度的判断,也不是一个关于学生学习本质的“发现”。而且“非常难”是主观判断,不太可能是演讲者的核心发现。 C. 每个学生都能努力理解材料。 这个选项听起来积极,但它强调的是“每个学生都能”,这在现实中未必成立,而且也不是一个基于观察得出的科学发现。它更像是一种理想化的信念。 D. 智商并不是影响学生成绩的唯一因素。 这个选项符合许多教育研究的核心结论,尤其是像Carol Dweck在关于“成长型思维”(growth mindset)的演讲中提到的观点:她发现,学生的态度、努力程度、学习策略等非智力因素对学习成绩有巨大影响。她在公立学校教数学时,注意到有些IQ不高的学生通过努力取得了好成绩,而有些聪明的学生却因为害怕失败而退缩。这让她意识到:**智商不是决定成功的唯一因素**。 因此,结合常见的教育演讲内容和逻辑推理,最合理的答案是: **D. IQ wasn’t the only factor that influenced students’ performance.** **解题过程总结:** 1. 题目问的是“演讲者在公立学校教数学时发现了什么”。 2. 分析四个选项,排除表面现象(A、B)和过于理想化(C)的选项。 3. D选项揭示了一个深层次的教育发现,符合真实演讲(如TED演讲《The power of believing that you can improve》)中的核心观点。 4. 因此选择D。 **答案:** \boxed{D}

解析

本题考查对演讲内容核心观点的推理能力。关键点在于识别演讲者通过教学实践得出的深层次发现,而非表面现象。选项D揭示了教育研究中的重要结论:学生成绩受多种因素影响,智商并非唯一决定因素。这与卡罗尔·德韦克的“成长型思维”理论一致,强调努力、态度等非智力因素的作用。

选项分析

A. Some students could not finish homework assignments

此选项描述学生完不成作业的现象,但未涉及演讲者的核心发现,属于常见问题,缺乏深度。

B. Seventh-grade math was very difficult for most students

仅判断课程难度,主观性强且未体现教学中的关键观察,无法成为演讲者的重点结论。

C. Every student could work hard to understand the material

虽积极,但“每个学生都能”过于绝对,且未基于实证研究,更像是理想化信念而非科学发现。

D. IQ wasn’t the only factor that influenced students’ performance

符合教育研究中“成长型思维”的核心观点:演讲者可能观察到智商高的学生因害怕失败而退缩,而努力的学生取得好成绩,从而得出非智力因素的重要性。

  • The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding.

  • "There is a senseless concept that children grow up and leave home when they're 18,and the truth is far from that,"says sociologist Larry Bumpass of the University of Wisconsin.Today,unexpected numbers of young adults are living with their parents."There is a major change in the middle class,"declares sociologist Allan Schnaiberg of Northwestern University,whose son,19,moved back in after an absence of eight months.Analysts list a variety of reasons for this return to the nest.The marriage age is rising,a condition that makes home and its pleasantness particularly attractive to young people.A high divorce rate and a declining remarriage rate are sending economically pressed and emotionally hurt survivors back to parental shelters.For some,the expense of an away-from-home college education has become so extremely great that many students now attend local schools.Even after graduation,young people find their wings clipped(夹住) by skyrocketing housing costs.Living at home,says Knighton,a school teacher,continues to give her security and moral support.Her mother agreed,"It's ridiculous for the kids to pay all that money for rent.It makes sense for kids to stay at home."But sharing the family home requires adjustments for all.There are the hassles over bathrooms,telephones and privacy.Some families,however,manage the delicate balancing act.But for others,it proves too difficult.Michelle Del Turco,24,has been home three times-and left three times."What I considered a social drink,my dad considered an alcohol problem,"she explains."He never liked anyone I dated,so I either had to hide away or meet them at friends'houses."Just how long should adult children live with their parents before moving on?Most psychologists feel lengthy homecomings are a mistake.Children struggling to establish separate identities,can end up with"a sense of inadequacy,defeat and failure."And aging parents,who should be enjoying some financial and personal freedom,find themselves stuck with responsibilities.Many agree that brief visits,however,can work beneficially.63.According to the author,there was once a trend (趋势) in the U.S ____ .A.for middle class young adults to stay with their parents.B.for young adults to get jobs nearby in order to live with their parents.C.for married young adults to move back home after a lengthy absence.D.for young adults to leave their parents and live independently.64.Which of the following does not account for young adults returning to the nest? ____ A.Young adults find housing costs too high.B.Quite a number of young adults attend local schools.C.Young adults are psychologically and intellectually immature.D.Young adults seek parental comfort and moral support.65.One of the disadvantages of young adults returning to stay with their parents is that ____ .A.the young adults tend to be overprotected by their parentsB.there will unavoidably be inconveniences in everyday lifeC.most parents find it difficult to keep a bigger family goingD.public opinion is against young adults staying with their parents66.The word"hassles"in the passage (Para.3,Line 4)probably means ____ .A.agreementsB.worriesC.disadvantagesD.quarrels
