Well, sort of.But as time goes by, we tend to blame age 24 problems that are not necessarily age—related.“When a teenager can’t find her keys,she thinks it's because she’s distracted or disorganized,”says Paul Gold.“A 70-year-old blames her 25 .”In fact,the 70-year-old may have been 26 things for decades.In healthy people,memory doesn’t worsen as 27 as many of us think.“As we 28 ,the memory mechanism isn’t 29 ,”says psychologist Fergus Craik.”It’s just inefficient.”/The brain’s processing 30 slows down over the years,though no one knows exactly 31.

Answer the questions below each passage by choosing A, B, C and D. Mark your answers on ANSWER SHEET 1.Passage OnePrior to the 20th century, many languages with small numbers of speakers survived for centuries. The increasingly interconnected modern world makes it much more difficult for small language communities to live in relative isolation, a key factor in language maintenance and preservation.It remains to be seen whether the world can maintain its linguistic and cultural diversity in the centuries ahead. Many powerful forces appear to work against it :population growth, which pushes migrant populations into the world’s last isolated locations; mass tourism; global telecommunications and mass media; and the spread of gigantic global corporations. All of these forces appear to signify a future in which the language of advertising, popular culture, and consumer products become similar. Already English and a few other major tongues have emerged as global languages of commerce and communication. For many of the world’s peoples, learning one of these languages is viewed as the key to education, economic opportunity, and a better way of life.Only about 3,000 languages now in use are expected to survive the coming century. Are most of the rest doomed in the century after that?Whether most of these languages survive will probably depend on how strongly cultural groups wish to keep their identity alive through a native language. To do so will require an emphasis on bilingualism(mastery of two languages). Bilingual speakers could use their own language in smaller spheres---at home, among friends, in community settings---and a global language at work, in dealings with government, and in commercial spheres. In this way, manysmall languages could sustain their cultural and linguistic integrity alongside global languages, rather than yield to the homogenizing(同化的)forces of globalization.Ironically, the trend of technological innovation that has threatened minority languages could also help save them. For example, some experts predict that computer software translation tools will one day permit minority language speakers to browse the Internet using their native tongues. Linguists are currently using computer—aided learning tools to teach a variety of threatened languages.For many endangered languages, the line between revival and death is extremely thin. Language is remarkably resilient(有活力的),however. It is not just a tool for communicating, but also a powerful way of separating different groups, or of demonstrating group identity. Many indigenous(原生的,土著的)communities have shown that it is possible to live in the modern world while reclaiming their unique identities through language.41.Minority languages can be best preserved in __________.A.an increasingly interconnected worldB.maintaining small numbers of speakersC.relatively isolated language communitiesD.following the tradition of the 20th century42.According to Paragraph 2, that the world can maintain its linguistic diversity in the future is _______.A.uncertain B.unrealistic C.foreseeable D.definite43.According to the author, bilingualism can help_________.A.small languages become acceptable in work placesB.homogenize the world’s languages and culturesC.global languages reach home and community settingsD.speakers maintain their linguistic and cultural identityputer technology is helpful for preserving minority languages in that it_________.A.makes learning a global language unnecessaryB.facilitates the learning and using of those languagesC.raises public awareness of saving those languagesD.makes it easier for linguists to study those languages45.In the author’s view, many endangered languages are________.A.remarkably well-kept in this modern worldB.exceptionally powerful tools of communicationC.quite possible to be revived instead of dying outD.a unique way of bringing different groups togetherPassage TwoEveryone,it seems,has a health problem。

一、简答题(30分)(3分)对一批结构钢材抽样检查,3个试件得到的屈服点分别为345MPa,380MPa, 1、390MPa,问这批钢材的实际屈服点应定为何值?在国家标准牌号中属于哪一等级的钢材?答: 345MPa [2分] / 属于Q345等级钢材。

[1分]2、(3分)地震荷载是一种反复作用的荷载,但钢结构受地震作用时的强度计算不采用疲劳应力幅公式的计算公式,简述其原因?答:主要是循环次数不同,地震荷载是循环次数较少的反复作用。

[3分]3、(3分)简述残余应力降低轴压构件刚度的原因。

答:残余应力的合力是自平衡的,故截面上一定有残余压应力。

残余压应力和外荷载引起的压应力叠加,将在名义应力(外荷载引起的应力)小于屈服点时达到屈服,从而使得构件提前进入非弹性变形。

[3分] 4、(3分)受弯、拉弯、压弯条件下的构件强度设计通常采用弹塑性准则。

请问:(a)何为弹塑性准则?(b)采用弹塑性准则有何意义?(c)何种受力状况下不宜采用该准则?答:(a)考虑在弯矩作用下的弯曲应力在构件的翼缘和腹板内有适度(有限)的塑性发展。

〔1分〕(b)尽可能充分利用材料强度,发挥其承载能力,节约钢材。

〔1分〕(c)一般在动力荷载、疲劳荷载状况下、受压翼缘宽厚比较大时,不宜采用弹塑性强度准则。

〔1分〕5、(3分)有人评说:“当轴心压力小、构件长度大的情况下,采用格构柱具有价值”。

请问(a)你是否同意此观点,(b)并说明理由。

答:(a)同意。

〔1分〕(b)因为轴心压力小时,依据强度要求只需要较小的截面积;当构件较长时,容易失稳,需要较大的截面回转半径,所以采用较小截面规格的型材肢件,拉开一段距离的截面布置,可达到较大的回转半径,从而使构件同时满足强度和整体稳定的要求。

〔2分〕6、(2分)工字型截面主梁在集中荷载(例如由次梁传来、由支座反力引起等)处应验算局部承压强度。

如果局部承压强度不满足,有人说:“可采取(a)增加主梁翼缘板厚度,(b)增加主梁翼缘宽度,(c)增加主梁腹板厚度,(d)增加主梁腹板高度,(e)主梁设置支承加劲肋,(f)增加集中荷载与主梁的接触长度等措施”。

你认为哪些是既有实效又经济合理的措施?答:(e)和(f)都是有效而又经济合理的措施,当梁的高度和跨度较小时,(c)也可能较经济。

〔共2分,答对2点即可〕7、(3分)剪力中心是指构件的横向荷载通过此中心位置时只会产生弯曲而不会引起扭转。

请用圆点“S”在以下三个截面形式的构件图中定性地标出它们的剪力中心位置。

答:如下图所示。

〔各1分〕8、(4分)防止钢构件局部稳定的设计准则通常有等稳定准则、强度准则和实际应力小于局部稳定临界应力准则等三种情况。

工字型截面梁的受压翼缘局部稳定的宽厚比控制要求为b/t ≤ 15(235/fy)。

请问(a)该宽厚比控制采用了什么设计准则?(b)该准则的含义是什么?(c)有人评说:“实际工程中的梁如果受压翼缘不满足该宽厚比要求,则必然会发生局部失稳”,你是否赞同该观点?并说明理由。

答:(a )采用了强度准则。

〔1分〕(b )要求板件的屈曲临界应力不小于(或大于等于)板材的屈服强度。

〔1分〕(c )不赞同该观点,因为该设计准则较保守,控制板件的局部失稳不先于强度破坏的发生。

板件是否失稳,关键是板件中的实际所受的应力是否大于板件的屈曲临界应力。

尽管没有满足上面的宽厚比要求,但是如果实际应力小于板件的屈曲临界应力,板件不会局部失稳。

〔2分〕9、(3分)两块钢板采用对接焊缝连接,有时要采用坡口,有时又可不采用坡口,设计时根据什么条件来确定要不要采用坡口?为什么?答:薄板不采用坡口,厚板应采用坡口。

[2分] / 前者不必采用坡口也能焊透,可以省去坡口加工;后者如不采用坡口,将耗费焊材、工时,且厚度较大的焊缝容易引起残余应力和焊接变形。

[1分]10、(3分)假如钢板的净截面破坏不发生,高强度螺栓摩擦型连接的破坏准则是什么?为什么采用这样的判断准则?答:外力(剪力)大于连接面(接触面)的抗滑移承载力(静摩擦力),导致滑移发生。

[2分] / 一旦滑移发生,结构(连接)引起瞬间变形抑或振动。

[1分]二、计算题(70分)1、(15分)图示轴心受压焊接圆形钢管柱φ450×12,A=165.04cm 2,i=15.49cm,材质为Q345,钢材设计强度f=310N/mm 2,压力设计值P=2500kN 。
