Text 3 In the idealized version of how science is done,facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work.But in the everyday practice of science,discovery frequently follows an ambiguous and complicated route.We aim to be objective,but we cannot escape the context of our unique life experience.Prior knowledge and interest influence what we experience,what we think our experiences mean,and the subsequent actions we take.Opportunities for misinterpretation,error,and self-deception abound.Consequently,discovery claims should be thought of as protoscience.Similar to newly staked mining claims,they are full of potential.But it takes collective scrutiny and acceptance to transform a discovery claim into a mature discovery.This is the credibility process,through which the individual researcher’s me,here,now becomes the community’s anyone,anywhere,anytime.Objective knowledge is the goal,not the starting point.Once a discovery claim becomes public,the discoverer receives intellectual credit.But,unlike with mining claims,the community takes control of what happens next.Within the complex social structure of the scientific community,researchers make discoveries;editors and reviewers act as gatekeepers by controlling the publication process;other scientists use the new finding to suit their own purposes;and finally,the public(including other scientists)receives the new discovery and possibly accompanying technology.As a discovery claim works it through the community,the interaction and confrontation between shared and competing beliefs about the science and the technology involved transforms an individual’s discovery claim into the community’s credible discovery.Two paradoxes exist throughout this credibility process.First,scientific work tends to focus on some aspect of prevailing Knowledge that is viewed as incomplete or incorrect.Little reward accompanies duplication and confirmation of what is already known and believed.The goal is new-search,not re-search.Not surprisingly,newly published discovery claims and credible discoveries that appear to be important and convincing will always be open to challenge and potential modification or refutation by future researchers.Second,novelty itself frequently provokes disbelief.Nobel Laureate and physiologist Albert Azent-Gyorgyi once described discovery as“seeing what everybody has seen and thinking what nobody has thought.”But thinking what nobody else has thought and telling others what they have missed may not change their views.Sometimes years are required for truly novel discovery claims to be accepted and appreciated.In the end,credibility“happens”to a discovery claim–a process that corresponds to what philosopher Annette Baier has described as the commons of the mind.“We reason together,challenge,revise,and complete each other’s reasoning and each other’s conceptions of reason.”31.According to the first paragraph,the process of discovery is characterized by its

  • A.uncertainty and complexity
  • B.misconception and deceptiveness
  • C.logicality and objectivity
  • D.systematicness and regularity

该题定位于第一段。文章第一段第二句话提到“But in the everyday practice of science,discovery frequently follows an ambiguous and complicated route.”,即“但是在日常的科学研究中,发现通常遵循一种模糊复杂的路径”。A项uncertainty and complexity是对文中ambiguous and complicated的同义替换,所以为正确答案。B项是利用文中最后一句话“Opportunit

论说文:根据下述材料,写一篇600字左右的论说文,题目自拟。

最近在网上,“美国害怕了”“日本吓傻了”“欧洲后悔了”之类的文章,总能赚取不少莫名点击。在此类文章的始作俑者眼里,标题就是一枚带着诱饵的鱼钩,不加点“刺激”的猛料,就无法吊起胃口。然而,纵观这些所谓“爆款”文章,其内部水平却了无新意,令人担忧。比如,有的一味夸大、以偏概全,高喊《在这些领域,中国创下多个“世界第一”!无人表示不服》;有的任意拔高、贻人口实,鼓吹《别怕,中国科技实力超越美国,居世界第一》;有的一厢情愿、照单全收,将国外的只言片语,放大成“中国在世界舞台上占据中心位置”“中国现在是全球第一经济体”等声音。特别是“跪求体”“哭晕体”“吓尿体”等浮夸自大文风频现,消减媒体公信力、污染舆论生态,扭曲国民心态,不利于成风化人、凝聚人心,构建清朗网络空间。

问答题

是否生孩子是每个家庭都要面临的选择。有人认为孩子是一个家庭必备的成员,但实际上,

孩子是奢侈品.穷人不应该生孩子。

首先,孩子童年容易不快乐。生孩子首先要考虑的便是经济条件,只要家庭经济条件好,孩子就能拥有快乐的童年。如果家庭经济条件差,那么孩子的很多喜好都不能满足,孩子的童年很难快乐。对某地一所中学的孩子进行抽样调查,发现家庭经济条件越差,孩子越容易产生自卑心理,越容易不快乐。为了让每个孩子拥有快乐的童年,穷人就不应该生孩子。

其次,孩子长大后不能拥有好的生活。培养孩子长大成才是每一位家长的愿望,但由于贫穷,家长不能够给孩子提供优质的教育资源,这使得孩子从小便落于人后,长大后也只能成为底层劳动人民,不能拥有好的物质生活,并且世世代代只能重复如此。既然如此,为了杜绝这种事情的发生,穷人就不应当生孩子。

再者,穷人生孩子会使父母生活变得不幸福。养育孩子需要付出时间成本和金钱成本,并且在养育孩子过程中需要夫妻中的一方放弃工作照顾孩子,如此就既减少了经济来源。又加大了经济开销,由此造成,夫妻的生活质量严重下降,生活变得不幸福。所以,为了不降低夫妻的生活质量,就不应该生孩子。

最后,父母与子女之间更容易产生矛盾。一个人的教育水平与其经济收入成正相关性,整体而言,相较于经济条件好的家庭而言,经济条件差的家庭其父母受教育的水平更低。可见,贫困家庭的孩子更容易与父母产生矛盾。

总之,不论从孩子角度还是父母角度考量.穷人都不应该生孩子。
