题目解答

答案

我们来一步步分析这个题目: 题目问的是:“人们对转基因食品(GM foods)的主要担忧是什么?” 选项如下: A. 一些转基因食品没有标注所需的信息 B. 它们可能会带来我们尚未了解的危害 C. 它们的味道和传统食品不一样 D. 种植转基因作物会破坏环境 --- ### 第一步:理解题干关键词 - **people's main concern**:人们的主要担忧,意味着这是一个广泛存在的、被普遍关注的问题。 - **GM foods**:转基因食品,是指通过基因工程技术改变了其遗传物质的食品。 --- ### 第二步:分析各个选项 **A. 一些转基因食品没有标注所需的信息** - 这是一个关于“标签”或“知情权”的问题,虽然在某些国家确实存在关于转基因食品是否应强制标注的争议,但这不是人们普遍最关心的核心问题。 **B. 它们可能会带来我们尚未了解的危害** - 这是一个关于**安全性**的问题,是公众对转基因食品最常表达的担忧之一。许多人担心转基因食品可能对健康有长期的、未知的负面影响,这是目前最普遍的担忧。 **C. 它们的味道和传统食品不一样** - 这是一个主观感受的问题,虽然可能有部分人不喜欢转基因食品的味道,但这不是主要的、普遍的担忧。 **D. 种植转基因作物会破坏环境** - 这是一个环境问题,确实有科学家和环保组织关注转基因作物对生态的影响,比如抗虫作物可能导致害虫产生抗药性,或转基因作物可能影响非目标生物等。但相比对**人类健康**的担忧,环境问题不是公众最关注的焦点。 --- ### 第三步:选择最符合“main concern”的选项 综合来看,**B选项**“它们可能会带来我们尚未了解的危害”最符合“人们对转基因食品的主要担忧”。 --- ### 最终答案: $$ \boxed{B} $$

解析

本题考查对转基因食品(GM foods)争议焦点的理解。关键在于识别公众对转基因食品的主要担忧。解题核心在于区分选项中普遍性和关键性的问题:

  • 安全性始终是转基因食品争议的核心,尤其是潜在的未知风险。
  • 其他选项(如标签、环境、风味)虽存在争议,但并非最普遍的担忧。

选项分析

A. 未标注信息

此选项涉及知情权问题,但并非公众最关注的核心。即使存在标签不规范的情况,这更多属于监管问题,而非直接威胁。

B. 潜在未知危害

安全性是转基因食品的核心争议点。公众普遍担心转基因食品可能通过基因改变对健康造成长期或不可预见的负面影响,例如过敏反应或致癌风险。这是目前科学界和舆论场讨论最多的问题。

C. 味道差异

此选项属于主观体验,虽然部分消费者可能对风味有偏好,但这并非普遍性担忧,且与转基因技术本身的争议关联较弱。

D. 环境破坏

转基因作物可能对生态产生影响(如抗虫性导致害虫抗药性),但相比人类健康风险,环境问题在公众讨论中的关注度较低。

结论:B选项直接对应公众对转基因食品的核心担忧,即潜在的未知健康风险。

  • "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

  • 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.
