It is not so much what happens to each of us that determines our quality of life,
but rather our reaction to what happens. Though we may have no 36 in
unexpected events that happen to us, we most certainly have choice in 37 we
interpret what happens, and in what we choose to do about it. These choices make all
the38in how we experience our world and very much determine our39
of life.全品高考网
Neither does what we own40 a major role in quality of life. One person
with all the money and possessions in the world may have a41 life, while
another in the lowest income classes may42 love their life. It is what we do
with what we own that43 our level of satisfaction and joy in life. It's not what
you44 or what happens to you in life that 45 , but rather what you
do with it.全品高考网

lives.50 following habitual, reactive patterns which51 more of the
same, we can recognize and52 our old habits to move powerfully in the53
of creating the life we really want. Yet to do this, we must first find the 54 to
look at some of the disempowering, often unconscious 55 which get in the way
and don't serve to increase our quality of life. But by continually reminding ourselves
of our intention to be creators, we can transform our life.全品高考网

1．C 根据37空见可以看出答案，意思是“我们的生活品质很大一部分并非取决于发生了什么，而是我们的处事态度。纵然我们无法选择发生在我们
身上的意外，但我们理所当然可以选择怎样理解和处理所发生的事情。”
全品高考网全品高考网
2．D 解释同上。本题易误选A。全品高考网
3．A make all difference“大有影响”。Make troubles“制造麻烦事”，trouble作为可数名词，意思为“麻烦事，问题等”；make decisions“做出决定”；measure
应该和take搭配。这些选择造就了我们所体验生活的不同，并很大程度
上决定了我们的生活质量。
4．B 根据文章大意及第一句可知，此处应为“生活质量”，非“类型”和“水平”。5．B play a major role短语，意思为“我们所拥有的东西也不构成决定生活质量的主要因素。”全品高考网
6．A 拥有世界上所有财富的人也可能过着悲惨的生活。全品高考网
7．C 与上一句相对应，一个拥有全世界金钱和资产的人依然可能生活得很痛苦，而收入位于最低列的另外一个人则可能绝对热爱他的生活。本题易
误选D。
8．C 此句为强调句型（It…that…）。我们如何对待我们所拥有的才真正影响我们满意水准和生活乐趣。本题易误选D。全品高考网
9．D possess“拥有”，在意义上与上下文保持一致，符合题意要求；而lack 意为“缺乏”，need“需要”，reserve意为“保留；预计”均不合题意。句意
为“你拥有什么或者发生了什么都不重要，你怎样看待和处理这些才至
关重要。”全品高考网
10．D matter“有关系，有重要性”。本题易误选C。全品高考网
11．D 每时每刻，而不是每一次。参考47空可知。全品高考网
12．C make a mistake犯错误、弄错了；make a discovery发现；make a decision 做出决定；make a fortune赚一笔钱。生活的每一刻都在发生着什么。每
一刻我们也都在作出决定和判定到底发生了什么。全品高考网
13．A be conscious of“意识到”。句意为“通过有意识的选择怎样应付发生的事情，我们可以更接近我们生命中真正想要的。”本题易误选D。全品高考网14．B shift“改变，移动”，shift to/toward；alter，改变；differ，是difference的动词形式，意思是“不同……”，differ in...，“在某方面或某事上不同”的
意思；distinguish，后面常跟介词from或between，意思是：“从……
中区别出来，不同”。比较这四个词的意义及用法，可以看出只有B才
是正确答案。本题易误选D。
15．B 不再采用很少变化的习惯性地应对方式，这些方式（会）导致同样的结局。本题易误选C。全品高考网
16．A lead to“导致”。参考上句。lie in后加原因。本题易误选C。
17．B 句意为“我们可以意识到并将我们的旧习有力地向创造我们想要的生活方向转变。”
18．C in the direction of“朝……方向”。参考上句。全品高考网
19．D 然而要做到这一点，我们首先必须有勇气审视某些消沉面，通常无意识/潜意识行为会过来挡道，阻碍我们提升生活的品质。本题易误选C。全品高

第五套案例模拟试题
2014年招标师《案例分析》实战模拟卷汇总第五套 本试卷均为案例分析题(共7题，共100分)，要求分析合理，结论正确;有计算要求的，应简要写出计算过程。 第一题 某总承包企业拟开拓国内某大城市工程承包市场。经调查该市目前有A、B两个BOT项目将要招标。两个项目建成后经营期限均为15年。为了顺利进行投标，企业经营部将在该市投标全过程按先后顺序分解为以下几项工作：①投标申请;②接受资格审查;③领取招标文件;④参加投标预备会;⑤参加现场踏勘;⑥编制投标文件;⑦编制项目可行性研究论证报告; ⑧投送投标文件;⑨投标文件内容说明与陈述;参加开标会议;⑨签订合同。经进一步调研，收集和整理出A、B两个项目投资与收益数据，见表6-1。 问题 1.经营部拟定的各项投标工作的先后顺序有何不妥? 2.不考虑建设期的影响，分别列式计算A、B两个项目总收益的净现值。据估计：投A 项目中标概率为0.7，不中标费用损失80万元;投B项目中标概率为0.65不中标费用损失100万元。若投B项目中标并建成经营5年后，可以自行决定是否扩扩建，其扩建投资4000万元，扩建后B项目每年运营收益增加1000万元。按以下步骤求解该问题： (1)计算B项目扩建后总收益的净现值。 (2)将各方案总收益净现值和不中标费用损失作为损益值，绘制投标决策树。
(3判断B项目在5年后是否扩建?计算各机会点期望值，并做出投标决策。(计算结果均保留两位小数。) 第二题 某工程采用公开招标方式，招标人3月1日在指定媒体上发布了招标公告，3月6 日月12日发售了招标文件，共有A、B、、D四家投标人购买了招标文件。在招标文件规定的投标截止日(4月5日)前，四家投标人都递交了投标文件。开标时投标人D因其投标文件的签署人没有法定代表人的授权委托书而被招标管理机构宣布为无效投标。该工程评标委员会于4月15日经评标确定投标人A为中标人，并于4月26日向中标人和其他投标人分别发出中标通知书和中标结果通知，同时通知了招标人。发包人与承包人A于5月10日签订了工程承包合同，合同约定的不含税合同价为6948万元，工期为300天;合同价中的间接费以直接费为计算基数，间接费率为12%，利润为5%。在施工过程中，该工程的关键线路上发生了以下几种原因引起的工期延误： (1)由于发包人原因，设计变更后新增一项工程于7月28日～8月7日施工(新增工程款为160万元);另一分项工程的图样延误导致承包人于8月27日～9月12日停工。 (2)由于承包人原因，原计划于8月5日晨到场的施工机械直到8月26日晨才到场。 (3)由于天气原因，连续多日高温造成供电紧张，该工程所在地区于8月3日～8月5停电，另外，该地区于8月24 日晨～8月28日晚下了场特大暴雨。在发生上述工期延误事件后，承包人A按合同规定的程序向发包人提出了索赔要求。经双方协商一致，除特大暴雨造成的工期延误之外，对其他应予补偿的工期延误事件，既补偿接费又补偿间接费，间接费补偿按合同工期每天平均分摊的间接费计算。 问题 1.指出该工程在招标过程中的不妥之处，说明理由。 2.该工程的实际工期延误为多少天?应予批准的工期延长时间为多少天?分别说明每个工期延误事件应批准的延长时间及其原因。 3.图样延误应予补偿间接费为多少? 4.该工程所在地市政府规定，高温期间施工企业每日工作时间减少1h，企业必须给职每人每天10元高温津贴。若某分项工程的计划工效为1.50m2/h，计划工日单价为50元，高温期间的实际工效降低10%，则高温期间该分项工程每平方米人工费比原计划增加多少元?(费用计算结果保留两位小数。) 第三题

2019年公共英语一级考试模拟试题（1） World English is a course in the English language. It is intended for students whose native language is not English. It is a basic programme consisting of six stages. Each stage includes a Student Book，a Teacher‘s Book， a Workbook， and cassette recordings. World English is further supported by separate books of readings， by tests， and by visual(可视的)aids. Who is world English for? World English may be entered at any one of three different levels. The First Level， Books One and Two， is intended for students with little or no education In English. Books Three and Four make up the Second Level; they are suitable for students who have some knowledge of English. The Third Level， Books Five and Six， is intended for students who are concerned with improvement in the language. What does world English teach? World English teaches four basic skills of language：listening， speaking， reading， and writing. At all levels，each skill is presented systematically. In the First Level，listening and speaking receive more attention. In the latter books， reading and writing become more important. However，reading and writing activities are presented even in Unit One of book One; and listening and speaking exercises occur through Unit One of Book One; and listening and speaking exercises occur though Unite Ten of Book Six.

Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage 1 Questions 1 to 5 are based on the following passage. What exactly is a lie? Is it anything we say which we know is untrue? Or is it something more than that? For example, suppose a friend wants to borrow some money from you. You say “I wish I could help you but I’m short of money myself.” In fact, you are not short of money but your friend is in the habit of not paying his debt and y ou don’t want to hurt his feelings by reminding him of this. Is this rally a lie? Professor Jerald Jellison of the University of Southern California has made a scientific study of lying. (76)According to him, women are better liars than men, particularly w hen telling a “white lie”, such as when a woman at a party tells another woman that she likes her dress when she really thinks it looks awful. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise which they have no intension of fulfilling. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at: the lie from which the liar hopes to profit or gain in some way. Research has also be en done into the way people’s behavior changes in a number of small, apparently unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. T o the trained observer th ey are saying “I wish I were somewhere else now.” They also tend to touch certain parts of the face more often, in particular the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The tip of the nose is very sensitive to such changes and the increased pressures make it itch. Another gesture which gives liars away is what the writer Desmond Morris in his book Manwatching calls “the mouth cover”.(77)He says there are several typical forms of this, such as covering part of the mouth with the fingers, touching the upper-lip or putting a finger of the hand at one side of the mouth. Such a gesture 模拟题第五套 应用文写作专题(一) 网络监管主题 (一)给定材料 1.去年，胡锦涛总书记、温家宝总理先后通过网络关注民生、了解民意，今年全国“两会”期间许多网站也增设“网络访谈室”，多方听取民声。 “新城区铁二村局部出现地基下沉，导致附近住房出现墙体裂缝，危及该地住户安全。”家住西安市新城区铁二村的村民胡先生通过网络向市政府反映了这一情况。 “根本没想到问题这么快就得到解决。”胡先生高兴地说。此事经新城区和市政府相关部门协调后，西安铁路局立即组织人员帮助住户搬离危房，同时对下沉地基进行抢修，并对危房住户在搬迁中造成的损失，给予相应的补助。在市政府网站上，此事的处理结果已经公布。 中国互联网络信息中心发布的《第23次中国互联网络发展状况统计报告》显示，截至2008年底，我国网民数已经达到2.98亿，居世界第一，互联网已经成为一个不可忽视的舆论宣传阵地。 2008年6月20日，胡锦涛总书记考察人民日报社时专门前往人民网看望编辑、记者，并通过强国论坛的视频直播和网友在线交流。胡锦涛表示，互联网是了解民情、汇聚民智的一个重要的渠道。 2009年2月28日，温家宝总理与网友在线交流并接受中国政府网和新华网联合专访时说：“想和网友交流是我期盼已久的，我觉得这种交流能使我看到网友的意见和要求。” 今年3月份召开的全国“两会”，首次设立“网络访谈室”，代表委员们通过这一渠道和网民在线交流，广泛听取民声，了解民意。 党和政府越来越关注网络，并且正在积极通过这种新的渠道鼓励民众参政议政，解决热点问题。这一系列的变化表明，我国网民通过网络“参政议政”已经迈出了里程碑式的一步。 2.在党政高层不断关注、重视“网络参政议政”的同时，现实中的“网络参政议政”却略显尴尬。 “为了找这一部办公室电话，我来来回回打了将近10个电话!有的政府部门就不能为咱老百姓多想想，把和大家息息相关的信息及时、准确地发布到网上来。”西安市民李先生无奈地抱怨，他因车辆问题寻找某局一个处室电话时，按照该局官方网站上留下的电话拨打过去，却被告知拨打另一部电话，按照指示打过去后又是同样的情况，反反复复近10次之多。 大多数网站区域分明，相关信息更新及时。然而，部分职能部门的官方网站甚至未能达到提供基本服务功能的水平。用网民“砖头”的话来说：“这类网站徒有形式，内容匮乏，很多设计好的内容不提供可用的链接地址，市民在其网站只能找到相关部门的职能介绍。” 一旅游网站经理张华表示，这些网络互动距离真正意义上的“参政议政”，还有很长的一段路要走，如果没有这些细节做基础，网络“参政议政”将成一纸空文。网络的发展，既需要网民不间断的支持，也需要政府机关为民众提供及时有效的信息，建好与群众互动交流的平台。湖南自考学位英语模拟试题及答案详解(一)
