meaningful relationships and it can as affect our creerr jobs.If you recognize the fact that youarenee thatbarrier to enjoingyouiheyou'vetaken theenibyepting tha itfor you.A lot of people feel shy because they have ow sef-respeet and feel unworthy when compa-ring themselves to others and so find it difficult to communicate with others whom they don'tknow.However,if you do feel as though you have nothing to say one of the best ways of overcoming your shyness is to focus your attention on the other person instead.The shy person hasswitched the focus onto someoneelse and that will be met by a great sense of appreciation bythe other party as we are all only too aware that most people don't need to be given too much ofan excuse to talk about themselves.Involved in these kinds of conversations,you are challenging yourself and overcoming what youfelt to be a problem and with that comesan increased sens of yourown self-esteem.This oum willbe repeated each time you do it until you'll feel confident enough to hold your own in most.Like any negative thought,a determination to beat shyness and not to let it defeat you andadopting an attitude to support that is the key to overcoming it.32.What does the author intend to tell us in Paragraph 2?A.The cause of shyness.B.The features of shyness.C.The harmful effect of shyness.D.The relationship between ability and shyness.33.Why do people feel shy when communicating with others?A.They are lacking in confidence.B.They are often made fun of.C.They usually criticize themselves.D.They are sometimes looked down upon.34.What does the author advise people to do?A.Get involved in more parties.B.Have a good talk with strangers.C.Keep a firm belief in achieving goals.D.Participate in as many activities as possible.35.What's the most suitable title for the text?A.Tips of Handling ShynessB.Tips of Finding ShynessC.How Shyness Affects PeopleD.How Shyness Is Overcome第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出填入空白处的最佳选项。选项中有两项为多余选项。What can help us when we fail?Failure is a part of life since our earliest moment of life.Somewhere along the way,wethink of failure as something bad.36.So the question isn't whether you want to fail or not,but how quickly you can accept your failure learn something from it and try again.Don't criticize yourself or stop trying.37.Babies don't give up until they learn to walk.If you really want to change somebehavior or learn to do something new,don't give up trying.You may get disappointed by thelack of progress sometimes,but if you give up,your progress will come to an end.38There is a certain power in optimistic thinking whether you believe it or not.Taking an opti-mistic attitude can open you up to more possibilities than usual.Kids don't ask whether they can dosomething or not-they know they can And that's one of the values we so cherish()in children.Learn to rely on yourself first,then others.Those who are self-reliant can bounce()back more quickly than those who aren't.39.Becoming self-reliant is easier than it sounds-become your own best friend,do eve-rything that you can possibly do for yourself and learn what your strengths and weaknesses are.【先知模拟卷·新课标·英语〈一〉（含听力）·共8页·第5页】

钨酸铵晶体。③由上述分析可知，该可逆反应正反应是放热(5)经计算可知WO2.中十5价和十6价的钨元反应，温度越低越有利于衡正移，CO2的衡素之比为1：4，设样品中WO2.9的物质的量分转化率就越大。由图观察知T3小于T4时对应数为x,则日x:(告x十1-)=1：7，解得的CO2的衡转化率，b点小于已达衡的a点，说明b点还未到衡状态。已知v(a)正=x景0.825，故有62,5%的w0,转化为了(a)逆、(c)正=o(c)逆，与a点相比，c点温度更蓝钨。高且反应物浓度更大故o(c)正>v(a)正，则有(6)图1和图2均由钨氧八面体WO。构成，其中v(c)送>v(a)递；与a点相比，b点温度更低且生顶点为氧原子，八面体体心为钨原子。图1由6成物浓度更小故(a)逆>℃(b)逆，那么可得个正八面体组成，含有6个W;从上往下可看作(c)逆>v(a)逆>v(b)逆).由题知v(a)、z(b)、由5层氧原子构成，每层氧原子个数分别为1、(c)分别代表这三点的逆反应速率，则v(c)>u(a)>w(b);4、9、4、1,共19个氧原子，故图1为W6O。。图④由图1可知相同温度下反应I进行的最快，2由7个正八面体组成，含有7个W;从上往下所使用的催化剂效果最好，相应活化能E。最可看作由5层氧原子构成，每层氧原子个数分别为2、6、8、6、2，共24个氧原子，故图2为小；由Arrhenius经验公式RTlnk=号+c知W,O8a。图2直线的斜率为一E。;由正切函数知识知0一19.【答案】(1)①A、B、D(3分，只答对1个得1分，-Ea(m)>一Ea(n),则有Ea(m)Ka>Ke(2分)(2)起始时气体总物质的量为12mol,反应V、③u(c)>v(a)>v(b)(2分)V均达衡时，=1.2，则12=1.2×n(n为④m(2分)衡时气体总物质的量)，解得衡时气体总物(2)1(2分)4p(3分)75质的量为10mol,则气体总物质的量减小【解析】(1)①一定条件下往恒定容积的密闭容器12mol-10mol=2mol,由于反应V是气体总中充入1 mol CO2和3molH2,在不同催化剂作用物质的量不变的反应，则减少的2mol为反应W下发生反应CO2(g)+3H2(g)三CHOH(g)造成，衡时H2的物质的量为1，则十H2O(g)。某温度下：A.容器内气体压强保持反应VCO,(g)+3H,(g)一CH,OH(g)+H,0(g),那变化量1mol3molImol 1mol不变可推出气体的物质的量之和为定值；B.H?么衡时甲醇为1mol,即n1=1;此时若2=3，O的体积分数保持不变；D.混合气体的均相即衡时H2O(g)的物质的量为3mol,反应V产对分子质量不变，由气体的总质量为定值以及生1molH2O(g),则反应V产生2molH2O(g),M=m/n可推出气体的物质的量之和为定值；故A、B、D可判定该反应达到衡状态。C项，则量8.6一90Oe,那变化量2mol2mol无论是否达衡状态，温度不变，衡常数不么衡时CO2、H2、CH3OH、H2O、CO的物质变；E项，要注意CH3OH中存在O一H,每断裂的量分别为2mol、2mol、1mol、3mol、2mol,2molC=O的同时断裂3molO一H,该反应达CO2、H2、CHOH、H2O的物质的量分数分别为5,500,反应W的衡常数K。=1113到衡状态；②观察已经达到衡的ac段曲线可知该可逆1反应正反应是放热反应，温度越高衡常数越1oPX10P75小，温度相同衡常数相同，故：Kb=K>K。吉pX(号p)14p2>Ke;参考答案第5页共6页

Gestures have been used to replace words in many countries,and they are often specific to agiven culture.Gesture may mean something complimentary in one culture,but is highly offensive inanother..The gesture thumb-up"is commonly misinterpreted.In English,it is popularly known as"thumbs up",despite the fact that the action iscommoyperformed with only one hand.English-speaking Caucasians use it.to signal"OK"which is the same meaning as OK ring gesture.The two can in fact be used almost interchangeably.Avoid using this gesture in Northern Greece unless you want to invite a fight.While American,British and Australian would use the thumb-up to signal hitch-hiking to the drivers,this message willnot encourage a Greek driver or motorist to stop'to give them a ride..There are no right or wrong signals,only cultural differences.Lack of cultural understanding willlead to.disharmony among people from different cultures.When we know what to look for,suchencounters with other cultures are actually very interesting,fascinating and fun.It is certainly a greattopic to discuss over a cup of coffee and cakes.28.What did the man in the first paragraph do wrong?A.He misunderstood the waiter.B.He didn't realize cultural differences.C.He ordered something off the menu.4D.He made the signalin a rude way.29.What does the underlined word in the second paragraph mean?A.Full of admiration.B.Full of aggressionC.Full of complexity.D/Full of certainty30.What will happen if you make a thumb up toward a man in Northern Greece?A.He will stop to give you a lift.B He will get annoyed and fight against you.C.He will ask you to give him a lift.D.He will make the same signal toward you.31.What's the purpose of the passage?..A.To explain the meaning of different gestures.B.To tell stories about different cultures.C To adyise us to have an understanding of cultural differences.D.To persuade people from different countries to live in harmony.DEver feel like scratching yourself when you see others doing it?You're probably not alone.Thispractice,which seems to be socially contagious )could be more than just a sudden urge.Thisis according to the latest finding from Washington University.The researchers studied mice to see what went on in their brains when they saw other mnicescratching.During the experiments,a mouse was placed in front of a computer.screen to watchanother of its kind scratching.A few moments after watching the video,the live mouse would startscratching.The finding is interesting because earlier studies had shown that mice only show empathy(with individuals they know and that the mouse on the screen was a stranger for the live mouse.This means that empathy may have nothing to do with the need to scratch.When the researchers.analyzed the brain activity of the mice after.viewing the video,theyrecorded increased level of gastrin-releasing peptide(GRP).In the previous research,GRP is found to2
