10月19日大连几经[转自我看机警]

smart

昨天终于在大连以比较满意的结果（７３０）结束了我又一段回想起来颇有滋味的经历.大家都劝我在大连玩一玩再回沈阳.但我却急于回来,尽我所能回忆起来的所有几经来回报这里热心,真诚,无私的xdjm们.是你们的无私奉献和热情鼓励使我在那段灰暗的日子里时时感到本已远离我的兴奋感觉.昨天下午坐在车上,我绞尽脑汁所能回忆考场上的试题,但由于当时实在是太紧张了,只能回忆出一小部分,如下所附:
数学:
1)一个四边形,左下角为60度,右上角为直角,且该直角的两边都为X,问周长,用X表示.
2)sb sells item a and item b,earns gross profit of 10% of the price of item a, and 90% of  item b.the cost of a is three times of the cost of b.ask the percentage of average gross profit of a and b.
我设a的价格为a,b的为b.则有:a的成本为o.9a,b的为0.1b, o.9a =0.1b*3.
the percentage of average gross profit of a and b is: (0.1a+0.9b)/(a+b), 再将上式代入即得.
3)(最难)10个孩子捐衣物,共捐28件,捐的衣服的件数的range使2,(不止何意),问捐三件的人数可能为以下那个.a 0
                b 5
                c 9
4)速率为2r的距离d=0.415r^2+0.11r, 问速率为2r的ｄ比速率为ｒ的ｄ大多少．
５）１４２０在１到１００中有几个质数因子．
四个
６）问点（ｘ，ｙ）在第几象限？
１，ｘ＋ｙ＜０
２，！ｘ！－！ｙ！＞０
选ｅ
７）老几经，x^3y^2z>0 ?
1, x^2yz>0
2,xy>0
选ｃ
８）老几经像框那道题．
９）三位数ａｂｃ，ａ，ｂ，ｃ为９６的三个因子，求ｂ
１　三位数为奇数
２　百位数为８

第一篇（３５行），太紧张了，记不清了．企业pioneering 才能成功，大意如下：
调查表明，pioneering enterprise leader tend to achieve success,because their product can grasp the market early.
in the second para, the author mentioned three disadvantages of the study mentioned above:1)the study concentrate only on those who have been sucessful, while ignore the fact that in those entrepreneurs who have failed, there are also many pioneering ones.2) the employees who responded in the study-----3)-------
第二片老几经．maternal leave
第三篇老几经　生物钟
第四篇关于大陆板块漂移
先是说了一些科学事实，什么大陆板块在不断移动，地表与地幔ｍａｎｔｌｅ的组成．说由于pressure,使得高温物质逐渐远离earth core,从而冷却the base of mantle.正是由于阐述的事实，科学家解释了为什么在板块边缘，有很多火山：因为when continent bend down under the other continent, the surface performance is that the pressure 将高温物质压出地表，及岩浆．
还有一种理论解释（注意：两个解释不相互排斥）了为什么在一些非板块交界处却存在chains of vocano,说有什么地下高温物质形成了hot spot在地低下，当大陆板块漂移过来时，就在地表形成了火山链．（我个人理解就象底下固定一把刀，当上面有一块布移动过来时，刀便在布的表面形成划痕）于是，就使得vocano chain 的在板块中的相对位置反映了大陆板块的漂移走向．

逻辑：
１）research shows that 30%of all patients in a psyco--- hospital admits depression clinic,while only 15%of  all patients have antibody of a kind of virus, since only when infected by the virus, an person will obtain the antibody.thus the scientists conclude that it is the virus that cause the depression. ask support
i chooose less than 2% of people in general have the antibody.

2)a kind of birds return very early this spring, because the spring came early this year.but because of the lack of insect, the birds have less food, however, the birds thrive. ask the explanation.
i choose the number of predators of the birds have been influenced too.

3) a tutle living in a bay decrease in number, some people said that the cause is the pollution. while later some jellyfish was found to have toxin, so people think that it is the jellyfish that have poinson the turtle when turtle eat them. ask support
i choose another kind of blue turtle did not decrease in number, this kind of turtle do not eat jerryfish, but feed on plant

不过我现在正在担心作文呢，虽然自己花了很多时间把作文题都看了，但唯独露了新加的题库，我碰到的issue时constant change and innovation within the organization 那道题，是新题库中的。我觉得我好像跑题了，人家要求within the organization ,我总强调对于公司来说，创新的重要性。真担心呀，不过argument是老几经。
