托福TPO34口语Task4阅读文本： The Familiarity Principle People tend to develop a preference for this they have previously encountered, things they are familiar with. Social psychologists refer to this tendency as the familiarity principle. Given a choice between two similar items, one they have experienced before and another that is new, most people will choose the familiar item. This principle operates even when people are not conscious of their previous experience with an item. Once people have been exposed to an item – even if they do not recall having been exposed to it – they will tend to prefer that item over other items to which they have not been previously exposed. 托福TPO34口语Task4听力文本： Professor：Some researchers did an experiment related to this. What they did was they assembled a group of subjects, a group of students, and they showed these students a series of geometrical shapes. These were very distinctive shapes, a little unusual, not the kind of shapes students often see. But they only showed the students the shapes for a very short period of time, about a second. They also lowered the light in the room to make it even more difficult for the students to see the shapes. So the shapes were there for a split second in dim light and then they were gone.In the next step of the experiment, the researchers again showed the students some shapes, but this time they gave the students a longer time to look at them. And this time they showed the images in pairs, two at a time. In each pair, one shape was a shape the students had already seen for just a split second in dim light. And the other was some other shape that hadn't been shown to them before. After presenting each pair, the researchers asked the students to say which of the two shapes they liked better. Most of the time, the students preferred the shape they’d already seen earlier in the experiment. Now, if you asked them if they’d already seen that shape, they probably wouldn’t know for sure. But that didn’t matter. They still tended to prefer the shapes they’d already seen. 托福TPO34口语Task4题目： Explain how the experiment described by the professor illustrates the familiarity principle. 托福TPO34口语Task4满分范文： Familiarity principle is the tendency that people usually prefer things thatthey're familiar with to new ones, even when they're unconscious of their exposure to the item. And the professor illustrates this with an experiment. In the experiment, a group of students were first shown several geometrical shapes, which were really uncommon, for a very short period of time in dim light so that they hardly perceived the objects consciously. Then the researchers showed the students a pair of shapes, and allowed them longer time to look at those shapes, one of which was the shape they had seen in dim light in a flash, while the other, a new one. After that the researchers asked these groups of students which shape they preferred because of familiarity principle, they tended to prefer the one they had already seen to the one they hadn't seen even though they were uncertain whether they'd seen the shapes.

4的数字代表什么意思有什么含义 在中国民间，许多⼈都因“四”与“死”的发⾳相近，⾯对“四”有所忌讳，和西⽅社会对“⼗三”的忌讳是类似的。

那么，你知道4的数字代表什么意思吗?接下来就跟着店铺⼀起去看看数字4的含义吧。

数字4的含义(⼀) 数字4的含义：执⾏数 数字四代表物质的坚固性，也就是物质的组成和建造。

⼀个坚固的物质或实体，是它众多构成体的整体组合，同时它⾃⼰⼜是⼆个新的整体。

绝对的⼀以数字四来定义⾃⼰，因爲他同时是⼀个整体和所有构成体(创造)的组合。

埃及⼈运⽤四个简单的现象(⽕、风、⼟、⽔)来形容构成物质所必需的四元素的作⽤⾓⾊。

⽕是活跃的，凝结的法则;⼟是接收的、格式化的法则，风是细微的、沉思的法则，会影响⼒量的交换;⽔是总和，是⼈、⼟、⽔的组合法则，⽔也是⼀种在它们之上的物质。

数字4总是呈现出苦难的特质，它代表着⽣命中那些让你感觉受限、需要收敛⾃我的⽅⾯。

⾯对种种困难应该采取怎样的解决之道，我们在⾯对逆境的时⼜应当如何规范⾃⼰的⼯作⽣活，都需要极强的组织思维与⾃律性，数字4便是带给我们这样的⼈⽣课题。

数字4的含义(⼆) 关键词：限制、规范、服务 象征符号：四⽅型 属性：计算智商型 对应⾊彩;绿⾊ 五⾏：阴⽕ 星座排⾏：巨蟹 这个数字在形态上就像⼀把三⾓量尺，代表精算，中规中矩，同时每⼀笔都是直挺的，见棱见⾓，象征着死板，不知变通。

四季分春夏秋冬，⽅向分东南西北，物质存在的四元素分为⽕、⽔、风、地，数字4代表了完整的秩序。

数字4的物质平⾯结构就像⼀个正⽅盒⼦，坚固、完善、安全。

数字本质都带有原始的意义，1和2的结合创造了3，当组合成⼀个家庭时，就要靠数字4来稳定⽣存的基本“安全”，4的任务就是实现和显化。

正⾯优势 帮助他⼈，实际，秩序，效率，⾃律，组织⼒，可靠，实⼲，诚恳，有勇⽓，任劳任怨，未⾬绸缪，稳重，做事认真，坚定，忠实，逻辑分明 负⾯挑战 ⼼胸狭隘，情绪紧张，不妥协，过分固执，过于谨慎，约束，拒绝改变，⾃我保护，挑剔，嫉妒⼼，吝啬，⼼胸狭窄，缺乏想象⼒，说教，不变通，⽆趣乏味 恐惧 变化，不稳定，⽣活危机 数字4的含义(三) 起初，⼈们都认为“四”最⼀般的象征含义是四⽅和四时。

17CHAPTER 4SOLUTIONS TO PROBLEMS4.2 (i) and (iii) generally cause the t statistics not to have a t distribution under H 0.Homoskedasticity is one of the CLM assumptions. An important omitted variable violates Assumption MLR.3. The CLM assumptions contain no mention of the sample correlations among independent variables, except to rule out the case where the correlation is one.4.3 (i) While the standard error on hrsemp has not changed, the magnitude of the coefficient has increased by half. The t statistic on hrsemp has gone from about –1.47 to –2.21, so now the coefficient is statistically less than zero at the 5% level. (From Table G.2 the 5% critical value with 40 df is –1.684. The 1% critical value is –2.423, so the p -value is between .01 and .05.)(ii) If we add and subtract 2βlog(employ ) from the right-hand-side and collect terms, we havelog(scrap ) = 0β + 1βhrsemp + [2βlog(sales) – 2βlog(employ )] + [2βlog(employ ) + 3βlog(employ )] + u = 0β + 1βhrsemp + 2βlog(sales /employ ) + (2β + 3β)log(employ ) + u ,where the second equality follows from the fact that log(sales /employ ) = log(sales ) – log(employ ). Defining 3θ ≡ 2β + 3β gives the result.(iii) No. We are interested in the coefficient on log(employ ), which has a t statistic of .2, which is very small. Therefore, we conclude that the size of the firm, as measured by employees, does not matter, once we control for training and sales per employee (in a logarithmic functional form).(iv) The null hypothesis in the model from part (ii) is H 0:2β = –1. The t statistic is [–.951 – (–1)]/.37 = (1 – .951)/.37 ≈ .132; this is very small, and we fail to reject whether we specify a one- or two-sided alternative.4.4 (i) In columns (2) and (3), the coefficient on profmarg is actually negative, although its t statistic is only about –1. It appears that, once firm sales and market value have been controlled for, profit margin has no effect on CEO salary.(ii) We use column (3), which controls for the most factors affecting salary. The t statistic on log(mktval ) is about 2.05, which is just significant at the 5% level against a two-sided alternative.18(We can use the standard normal critical value, 1.96.) So log(mktval ) is statistically significant. Because the coefficient is an elasticity, a ceteris paribus 10% increase in market value is predicted to increase salary by 1%. This is not a huge effect, but it is not negligible, either.(iii) These variables are individually significant at low significance levels, with t ceoten ≈ 3.11 and t comten ≈ –2.79. Other factors fixed, another year as CEO with the company increases salary by about 1.71%. On the other hand, another year with the company, but not as CEO, lowers salary by about .92%. This second finding at first seems surprising, but could be related to the “superstar” effect: firms that hire CEOs from outside the company often go after a small pool of highly regarded candidates, and salaries of these people are bid up. More non-CEO years with a company makes it less likely the person was hired as an outside superstar.4.7 (i) .412 ± 1.96(.094), or about .228 to .596.(ii) No, because the value .4 is well inside the 95% CI.(iii) Yes, because 1 is well outside the 95% CI.4.8 (i) With df = 706 – 4 = 702, we use the standard normal critical value (df = ∞ in Table G.2), which is 1.96 for a two-tailed test at the 5% level. Now t educ = −11.13/5.88 ≈ −1.89, so |t educ | = 1.89 < 1.96, and we fail to reject H 0: educ β = 0 at the 5% level. Also, t age ≈ 1.52, so age is also statistically insignificant at the 5% level.(ii) We need to compute the R -squared form of the F statistic for joint significance. But F = [(.113 − .103)/(1 − .113)](702/2) ≈ 3.96. The 5% critical value in the F 2,702 distribution can be obtained from Table G.3b with denominator df = ∞: cv = 3.00. Therefore, educ and age are jointly significant at the 5% level (3.96 > 3.00). In fact, the p -value is about .019, and so educ and age are jointly significant at the 2% level.(iii) Not really. These variables are jointly significant, but including them only changes the coefficient on totwrk from –.151 to –.148.(iv) The standard t and F statistics that we used assume homoskedasticity, in addition to the other CLM assumptions. If there is heteroskedasticity in the equation, the tests are no longer valid.4.11 (i) Holding profmarg fixed, n rdintensΔ = .321 Δlog(sales ) = (.321/100)[100log()sales ⋅Δ] ≈ .00321(%Δsales ). Therefore, if %Δsales = 10, n rdintens Δ ≈ .032, or only about 3/100 of a percentage point. For such a large percentage increase in sales,this seems like a practically small effect.(ii) H 0:1β = 0 versus H 1:1β > 0, where 1β is the population slope on log(sales ). The t statistic is .321/.216 ≈ 1.486. The 5% critical value for a one-tailed test, with df = 32 – 3 = 29, is obtained from Table G.2 as 1.699; so we cannot reject H 0 at the 5% level. But the 10% criticalvalue is 1.311; since the t statistic is above this value, we reject H0 in favor of H1 at the 10% level.(iii) Not really. Its t statistic is only 1.087, which is well below even the 10% critical value for a one-tailed test.1920SOLUTIONS TO COMPUTER EXERCISESC4.1 (i) Holding other factors fixed,111log()(/100)[100log()](/100)(%),voteA expendA expendA expendA βββΔ=Δ=⋅Δ≈Δwhere we use the fact that 100log()expendA ⋅Δ ≈ %expendA Δ. So 1β/100 is the (ceteris paribus) percentage point change in voteA when expendA increases by one percent.(ii) The null hypothesis is H 0: 2β = –1β, which means a z% increase in expenditure by A and a z% increase in expenditure by B leaves voteA unchanged. We can equivalently write H 0: 1β + 2β = 0.(iii) The estimated equation (with standard errors in parentheses below estimates) isn voteA = 45.08 + 6.083 log(expendA ) – 6.615 log(expendB ) + .152 prtystrA(3.93) (0.382) (0.379) (.062) n = 173, R 2 = .793.The coefficient on log(expendA ) is very significant (t statistic ≈ 15.92), as is the coefficient on log(expendB ) (t statistic ≈ –17.45). The estimates imply that a 10% ceteris paribus increase in spending by candidate A increases the predicted share of the vote going to A by about .61percentage points. [Recall that, holding other factors fixed, n voteAΔ≈(6.083/100)%ΔexpendA ).] Similarly, a 10% ceteris paribus increase in spending by B reduces n voteAby about .66 percentage points. These effects certainly cannot be ignored.While the coefficients on log(expendA ) and log(expendB ) are of similar magnitudes (andopposite in sign, as we expect), we do not have the standard error of 1ˆβ + 2ˆβ, which is what we would need to test the hypothesis from part (ii).(iv) Write 1θ = 1β +2β, or 1β = 1θ– 2β. Plugging this into the original equation, and rearranging, givesn voteA = 0β + 1θlog(expendA ) + 2β[log(expendB ) – log(expendA )] +3βprtystrA + u ,When we estimate this equation we obtain 1θ≈ –.532 and se( 1θ)≈ .533. The t statistic for the hypothesis in part (ii) is –.532/.533 ≈ –1. Therefore, we fail to reject H 0: 2β = –1β.21C4.3 (i) The estimated model isn log()price = 11.67 + .000379 sqrft + .0289 bdrms (0.10) (.000043) (.0296)n = 88, R 2 = .588.Therefore, 1ˆθ= 150(.000379) + .0289 = .0858, which means that an additional 150 square foot bedroom increases the predicted price by about 8.6%.(ii) 2β= 1θ – 1501β, and solog(price ) = 0β+ 1βsqrft + (1θ – 1501β)bdrms + u= 0β+ 1β(sqrft – 150 bdrms ) + 1θbdrms + u .(iii) From part (ii), we run the regressionlog(price ) on (sqrft – 150 bdrms ), bdrms ,and obtain the standard error on bdrms . We already know that 1ˆθ= .0858; now we also getse(1ˆθ) = .0268. The 95% confidence interval reported by my software package is .0326 to .1390(or about 3.3% to 13.9%).C4.5 (i) If we drop rbisyr the estimated equation becomesn log()salary = 11.02 + .0677 years + .0158 gamesyr (0.27) (.0121) (.0016)+ .0014 bavg + .0359 hrunsyr (.0011) (.0072)n = 353, R 2= .625.Now hrunsyr is very statistically significant (t statistic ≈ 4.99), and its coefficient has increased by about two and one-half times.(ii) The equation with runsyr , fldperc , and sbasesyr added is22n log()salary = 10.41 + .0700 years + .0079 gamesyr(2.00) (.0120) (.0027)+ .00053 bavg + .0232 hrunsyr (.00110) (.0086)+ .0174 runsyr + .0010 fldperc – .0064 sbasesyr (.0051) (.0020) (.0052) n = 353, R 2 = .639.Of the three additional independent variables, only runsyr is statistically significant (t statistic = .0174/.0051 ≈ 3.41). The estimate implies that one more run per year, other factors fixed,increases predicted salary by about 1.74%, a substantial increase. The stolen bases variable even has the “wrong” sign with a t statistic of about –1.23, while fldperc has a t statistic of only .5. Most major league baseball players are pretty good fielders; in fact, the smallest fldperc is 800 (which means .800). With relatively little variation in fldperc , it is perhaps not surprising that its effect is hard to estimate.(iii) From their t statistics, bavg , fldperc , and sbasesyr are individually insignificant. The F statistic for their joint significance (with 3 and 345 df ) is about .69 with p -value ≈ .56. Therefore, these variables are jointly very insignificant.C4.7 (i) The minimum value is 0, the maximum is 99, and the average is about 56.16. (ii) When phsrank is added to (4.26), we get the following:n log() wage = 1.459 − .0093 jc + .0755 totcoll + .0049 exper + .00030 phsrank (0.024) (.0070) (.0026) (.0002) (.00024)n = 6,763, R 2 = .223So phsrank has a t statistic equal to only 1.25; it is not statistically significant. If we increase phsrank by 10, log(wage ) is predicted to increase by (.0003)10 = .003. This implies a .3% increase in wage , which seems a modest increase given a 10 percentage point increase in phsrank . (However, the sample standard deviation of phsrank is about 24.)(iii) Adding phsrank makes the t statistic on jc even smaller in absolute value, about 1.33, but the coefficient magnitude is similar to (4.26). Therefore, the base point remains unchanged: the return to a junior college is estimated to be somewhat smaller, but the difference is not significant and standard significant levels.(iv) The variable id is just a worker identification number, which should be randomly assigned (at least roughly). Therefore, id should not be correlated with any variable in the regression equation. It should be insignificant when added to (4.17) or (4.26). In fact, its t statistic is about .54.23C4.9 (i) The results from the OLS regression, with standard errors in parentheses, aren log() psoda =−1.46 + .073 prpblck + .137 log(income ) + .380 prppov (0.29) (.031) (.027) (.133)n = 401, R 2 = .087The p -value for testing H 0: 10β= against the two-sided alternative is about .018, so that we reject H 0 at the 5% level but not at the 1% level.(ii) The correlation is about −.84, indicating a strong degree of multicollinearity. Yet eachcoefficient is very statistically significant: the t statistic for log()ˆincome β is about 5.1 and that forˆprppovβ is about 2.86 (two-sided p -value = .004).(iii) The OLS regression results when log(hseval ) is added aren log() psoda =−.84 + .098 prpblck − .053 log(income ) (.29) (.029) (.038) + .052 prppov + .121 log(hseval ) (.134) (.018)n = 401, R 2 = .184The coefficient on log(hseval ) is an elasticity: a one percent increase in housing value, holding the other variables fixed, increases the predicted price by about .12 percent. The two-sided p -value is zero to three decimal places.(iv) Adding log(hseval ) makes log(income ) and prppov individually insignificant (at even the 15% significance level against a two-sided alternative for log(income ), and prppov is does not have a t statistic even close to one in absolute value). Nevertheless, they are jointly significant at the 5% level because the outcome of the F 2,396 statistic is about 3.52 with p -value = .030. All of the control variables – log(income ), prppov , and log(hseval ) – are highly correlated, so it is not surprising that some are individually insignificant.(v) Because the regression in (iii) contains the most controls, log(hseval ) is individually significant, and log(income ) and prppov are jointly significant, (iii) seems the most reliable. It holds fixed three measure of income and affluence. Therefore, a reasonable estimate is that if the proportion of blacks increases by .10, psoda is estimated to increase by 1%, other factors held fixed.。

我的四个心理花瓶每个人的心中都会有这样四个空花瓶，它们的形状各不相同，代表着各种不同的含义，随着我们的成长，我们在渐渐地往我们的花瓶中注水，或多或少，我们用它们来衡量自我，分析自我。

一、我的四个心理花瓶二、关于四个花瓶的分析1.花瓶1：课业、工作前景这是一个普通花瓶，瓶身较细，它的水位大概在三分之二左右。

花瓶中三分之二的水位，其一，它代表了我并没有在学业中投入饱和的百分百的精力，这也导致了我对所取得的既有成绩并不十分满意；其二，它代表了我对所学专业的工作前景已经有一定的了解，但并不是非常的充分，所以，我对未来工作方面的规划只有一个大致的方向，并未做出一个较为详细的规划。

花瓶的瓶身较细，随着不断地注水，水位的上升也比较快，意在告诉自己，关于课业、事业方面，只要付出足够的努力，所能得到的回报就会很明显。

2.花瓶2：人际关系这个花瓶是一个肚大颈小的瓶子，它的水位是全满，但花瓶的底部有一个小缺口。

花瓶中的全满水位，其一，它代表了我们家庭成员关系比较和谐，这主要得益于我的家庭是一个相对比较民主的家庭，家庭氛围非常融洽，家人们也都是比较开朗乐观的人；其二，它代表了我对自己的除亲属外的人际关系的满意，开朗外向的性格使我在交友方面更加得心应手。

这个花瓶肚大颈小的形状代表了我对自我人际关系总体感到很圆满，但，花瓶底部有一个小缺口，这说明了，如果没有持续地注水，有可能会导致人际关系的流失。

这个小缺口旨在提醒自我，对于人际关系这一块，我还有一些方面有待补缺补漏。

3.花瓶3：躯体健康和体力精力这是一个上宽下窄的花瓶，它的水位也是全满。

现在的我正步入青年期，一个精力旺盛的时期。

处于这个时期的我，身体可以说是很健康，比较少生病，也有很多精力去参与各种各样有趣的活动，也能经常去参与一些体育锻炼。

全满水位代表了，我自我感觉这个时期的我精力无限。

但，随着时间的快速流逝，我的精力也将会随之流逝。

所以这个上宽下窄的花瓶形状，说明了，水量的减少，水位会先缓慢下降再慢慢加快，也代表了精力会慢慢下降。

随着，我国信息技术的不断蓬勃发展，近年来我国医院的信息化建设取得了很大进展，各层级医疗机构相比从前都面临着激烈的市场竞争，需要为病患者提供更人性化、更合理的服务。

近年来我国医药卫生体制改革不断深化，人民健康状况和基本医疗卫生服务的公平性可及性持续改善。

自从2019年经历了一场突如其来的新冠肺炎疫情，医药卫生体系经受住了考验，为打赢新冠肺炎疫情防控阻击战发挥了重要作用。

坚持以习近平新时代中国特色社会主义思想为指导，以人民为中心的发展思想，坚持保基本、强基层、建机制，统筹推进深化医改与新冠肺炎疫情防治相关工作，把预防为主摆在更加突出位置，推动把以治病为中心转变为以人民健康为中心，继续着力解决看病难、看病贵问题，为打赢疫情防控的人民战争、总体战、阻击战，保障人民生命安全和身体健康提供有力支撑，抗击新冠肺炎的阻击战之所以可以取得成功医疗信息化建设在其中发挥了至关重要的作用。

此后，为落实《国务院办公厅关于促进“互联网+医疗健康”发展的意见》(国办发〔2018〕26 号)和卫健委《关于进一步推进以电子病历为核心的医疗机构信息化建设工作的通知》(国卫办医发〔2018〕20 号)，持续推进以电子病历为核心的医疗机构信息化建设，在《电子病历系统应用水平分级评价管理办法(试行)及评价标准(试行)》国卫办医函〔2018〕1079 号中，明确提出到 2019 年，所有三级医院要达到分级评价 3 级以上;到2020 年，所有三级医院要达到分级评价 4 级以上，二级医院要达到分级评价 3 级以上。

电子病历系统应用水平评级是全面评估各医疗机构现阶段电子病历系统应用所达到的水平，建立适合我国国情的电子病历系统应用水平评估和持续改进体系。

很多具有一定规模的中大型医院为了通过电子病历4级评审，花费较大精力对医院的信息化现状进行调研后，形成对标需求分析。

经过医院前期的基础医院信息系统的建设，包括数字化 HIS 系统、电子病历 EMR 系统、影像 PACS 系统、心电系统、病理系统、检验 LIS 系统、合理用药系统，以及此次信息化建设对标分析，查找差距，优化改造。

最终幻想4攻略复刻版剧情流程图文详解主要给大家介绍的是如何按照最终幻想4攻略剧情通关，最终幻想4攻略中每一个剧情的boss也都列出来了，不同的boss有不同的打法，大家还是按步骤来吧。

本作的故事破天荒的在地上、地下和月亮世界三个舞台上展开。

主要讲述了赤翼队长塞西尔对巴隆过以力量压迫奴役他国的做法非常不满，因而将自己的想法转达给国王。

不曾想却遭到追杀。

于是塞西尔决定与巴隆国战斗!在漫长的反抗生涯中，塞西尔经历了友情的背叛、爱情的美好以及自身身份的转变。

作为一个经典的RPG游戏系列，我们这次在IOS版上不但看到了一贯的一些经典系统，但是这一代是改变的一代，为什么这么说呢?因为游戏的系统从四代开始，游戏系统都会发生少许改变和发展。

例如基于三代发展出的技能系统和基于二代发展出的魔法习得系统等，可以看出史克威尔的用心。

最重要的是前三代游戏中的水晶，被赋予了更多元化的设定。

它不在是专为主角所独享，演变成了敌我双方都可使用的新形态。

而且由此展开的剧情也变成了互相争夺，不在是一方守护一方破坏的固定模式了。

其中最有亮点的是ATB(ACTIVE TIME BATTLE)战斗模式!舍弃了传统的回合制，采用了全新的时间槽即时战斗系统，使战斗不在是一成不变。

进入游戏后，首先选择游戏难度，小编选了困难，两个难度的进程什么的都一样，只是怪的伤害和血量不同。

首先是一段剧情介绍，赤翼队长塞西尔奉命去收集水晶，虽然善良的队长很不愿意从无辜的人们那里抢夺水晶，但是塞西尔迫于军人的服从而不得不去做这些违心的任务。

突然飞艇遭到的攻击(进入第一场战斗)。

战斗结束后，我们的主角塞西尔回到了王国，把水晶交给国王后，塞西尔忍不住向王国表示出了质疑，没想到这让他被降职，国王让塞西尔带着爆弹戒指去击败幻兽。

到这里，我们就要开始开始的剧情就结束了。

首先我们对游戏的操作做个简单的介绍，游戏采用的单摇杆的行动控制模式，像所有的RPG一样我们的角色都有装备和角色属性，而关于角色的所有信息都可以点击屏幕右上角的按钮后看到。

Unit4一、课文A sportswriter thinks he's met another crank. Instead, he finds a true winner.一位体育专栏作家以为他碰上了一个怪人。

结果他却发现了一个真正的赢家。

A Fan's NotesBill PlaschkeThe e-mail was in some respects similar to other nasty letters I receive. It took me to task for my comments on the Los Angeles Dodgers and argued that I had got everything wrong. However, the note was different from the others in at least two ways.一位球迷的评论比尔·普拉施基这封电子邮件在某些方面与我收到的其他刻薄的信件相似。

它痛斥我对洛杉矶道奇队的评论，并争辩说我把一切全都搞错了。

然而，这个评论与其他的评论至少有两个方面不同。

This note contained more details than the usual "You're an idiot." It included vital statistics on the team's performance. It was written by someone who knew the Los Angeles Dodgers as well as I thought I did.与通常那些“你是个白痴”的评论不同的是，这一评论含有更多的细节。

它包含了该队比赛表现的关键数据。

写这篇评论的人对洛杉矶道奇队的了解绝不亚于我自认为对它的了解。

And this note was signed. The writer's name was Sarah Morris.而且这一评论是署名的。

任务4 作出正确的决策（课后练习题参考答案）一、单项选择题1、C2、B3、C4、C5、A6、A7、A8、B9、A 10、B二、判断题1、错2、对3、错4、对5、错6、对7、错8、对9、错 10、对三、简答题1．决策在组织中有什么重要作用？随着现代科学技术水平的不断提高，市场竞争日趋激烈，影响组织运行的因素变得十分复杂，因为单凭个人经验或主观判断进行决策，是不能适应激烈多变的竞争环境的，管理者也难以作出正确、科学的判断。

可以说，管理者科学、理性的决策等于成功了一半，可见，决策对企业具有非常重要的作用，其重要性具体体现在：①决策决定了组织的生存和发展决策涉及组织生活的方方面面，大到组织的总体发展目标，小到日常管理工作中出现的问题，任何一个决策的正确与否都会影响到组织的正常运作。

正可谓“一着走错，全盘皆输”。

中外许多企业的沉浮经历，足以成为有力的佐证。

因此，每一个决策者必须清醒认识和估计各种情况，以更好地把握其变化规律，制定出科学、正确的决策，保证组织的持续发展。

②决策是组织各项管理职能部门运行的依据决策是管理的重要职能之一，决策也是各项管理职能部门运行的依据。

决策是一个方案，为各职能部门和全体员工指明努力方向和目标。

没有正确的经营决策，各职能部门就无法正常发挥功能，职能造成组织活动的无序甚至混乱。

③正确的决策是组织可持续发展的保证在科学技术发展迅猛、信息膨胀的今天，各种各样的情况层出不穷，任何组织都需要随时根据实际情况，及时、准确和科学地作出正确的决策，以适应社会，求得发展，否则只能面临被淘汰的命运。

2. 决策有哪些程序?要做出一个正确的决策，管理者需要自觉地遵循以下六个步骤：1. 认识决策需要决策过程的第一步就是要认识决策需要。

一些刺激因素通常会激发起决策需要的意识。

当组织环境中发生的变化带来了新的机遇或者威胁时，这些刺激因素就会显现出来。

除了来自于外部环境中的变化，激发决策需要的刺激因素还可能来自于组织内部管理者的行为。
