Changes in life
Over the recent years, I′ve seen great changes in my life. Many aspects are to be concerned, but by simply specifying how my family are better off now than ever before suffices it all. We used to live in a cramped and gloomy room, and things were not so good as we had to strive for light and even more fresh air. Now, in this spacious and luminous room that I¨m talking about, I′m leading a life that′s more than satisfactory and getting around here and there is no longer a big problem.

Over the past twenty years or so, great changes have taken place in our life. Take my family for example.
My parents contacted others mainly by sending them letters in the past. But now we Call long distance at home. And once my parents listened to the radio for news and other information. But now we get the news by watching TV. Another big change is in my living conditions. When they got married about twenty years ago, my parents lived in a small room crowded with fiirniture. But now we have moved into a big new three-room apartment. In short, our life has become comfortable and convenient.

How to Keep Healthy
It is absolutely necessary to take some exercise every day. Research shows that getting plenty of exercise make the heart beat faster and the lungs work harder. This strengthens the heart, reduces the chance of heart attack, and helps lower blood pressure. That's why more and more people are becoming active in various kinds of sports and exercises. Every morning many people get up early and take much exercise. Some practice shadowboxing and swordplay while others run, jog, walk or dance to music. In the afternoon, there are also many people keen on sports. Some play basketball or volleyball or table tennis, others go in for gymnastics or track events. Through sports and exercise, people become healthier and stronger.
范文三：

你好我有相关资料需要请Q

是可靠性要求，选C ，这是到原题

一般的形成性考核只要交卷了就已经出了成绩,直接刷新页面就可以看到.
累积成绩58分说明你的平均分数,比如你选了5门课,此次作业全部完成,那么形考成绩就会以平均分的形式出来,形考成绩必须高于60分才算通过,当然这只是作业,是你总成绩的一部分,其余学分还是要以书面考试的形式获得.
简单的说,就是你作业部分不及格,如果其中有试点教学课程,那么就要多注意了,试点教学课程作业不合格是不能参加统一考试的!

Forcing by my girl friend, I start cooking by making fried eggs. But suddenly after I cooked my very first meal in my life, I began to love cooking. Putting my stomach under my own control is the best way to keep healthy. Maybe this is an era that men take all the duties in a family except giving birth to a baby. Whatever, cooking is good life style and I really enjoy it. Hope some day I could cook for you guys, but you really need to wait.... 2nd, My life style has been more regular. Thank to the shuttle bus of my company, I have a chance to get up early and go home early, also sleep early(except tonight). But the breakfast in my company canteen is...I decide not to say that. 3rd, My Financial situation has never been worse. After I handed in my house rent, I have been tight in finance for almost 2 months. The house owner is somewhat disgusting, although looks nice. I hope I have my April salary before the end of May, or I will have nothing to fulfill the house rent. 4th, I have lost my direction. It was the first thought when I steped in my company. Because my work is just sustaining a product. Some people have worked for this product for 5 or 6 years and still do the same thing as before. This is terrible for me because, at school I have a direction, I know I should do projects, learn courses and get my degree. Now I don't see a future. What will I be after 3 or 4 years? It is a question I have to face and have to find an answer. And I really hope some experienced one discuss with me the answer for the 4th question. 追问： 还有呢？ 回答： 作业21-5CADDD6-10DBBCC11-15ADAAD16-20AAADA21-25DACAC 26-30BCABC31-35BDAAA26-40FFTTT 第四部分短文Keep healthy is very important to us.

百度：如果物体本身的大小和形状对研究它的运动没有影响或影响很小,我们就可以用一个有质量的点来代替整个物体,这个用来代替整个物体的与物体具有相同质量的点,叫做质点.
例如,在研究地球公转时,地球半径比日、地间的距离小得多,就可把地球看作质点,但研究地球自转时就不能把它当成质点.又如物体在平动时,内部各处的运动情况都相同,就可把它看成质点.所以物体是否被视为质点,完全决定于所研究问题的性质.
速度——表示物体运动的快慢程度的物理量.速度是矢量,有大小和方向,速度的大小也称为“速率”.

可做一柱形高斯面,两个底面分别在两个导体内部（与导体表面平行）,侧面垂直于导体表面.这样侧面无电通量,两个底面也因那里场强为零而没有电通量,故高斯面内电荷代数和为零.所以σ2=-σ3.
取其中一块导体内一点分析,这一点合场强应为零.由1中结论,两内壁内电荷等量异号,该点位于两内表面之外,其场强在此点抵消,从而剩下的两个外表面的电荷产生的场强也应等大反向.因为该点在两外表面之间,故两外表面电荷等量同号,所以选A.

第三次财务管理作业参考答案
1、每年折旧额=（750-50）/5=140（万元）
每年的净现金流量=净利润+折旧=销售收入-付现成本-折旧
=（1000-760-140）X（1-40%）+140=200（万元）
NCF0=-1000万元
NCF1——NCF4=200万元
NCF5=200+250+50=500（万元）
2、新旧设备投资差额=-24万元
新旧设备收入差额=10万元
新旧设备付现成本差额=-2万元
新旧设备税收成本差额=-1.2万元
则NCF0=-24万元
NCF1——NCF6=10-2-1.2=6.8（万元）
3、1）每年的净营业现金流量=407000元
投资现值=454000X（P/A,10%,5）=1721114(元)
收益现值=407000X（P/A,10%,10）X(1+10%)-5=1553130(元)
NPV=投资现值-收益现值=1553130-1721114=-167984（元）
项目不可行
2）现值指数PI=收益现值/投资现值=1552930/1721114=0.902
项目不可行
3）选I=8%，NPV=4.7，
当I=？，NPV=0
当I=9%,NPV=-6.8
则 （I-8%）/(9%-8%)=(0-4.7)/（-6.8-4.7）
I=8.41%
4、投资现值=52+5.2X（P/A,10%,5）=71.7(万元)
收益现值=66.6万元
NPV=66.6-71.7=-5.1(万元)
5、甲设备 NCF0=-10000元
NCF1——NCF5=3200元
回收期=10000/3200=3.125（年）
平均报酬率=3200/10000=32%
乙设备
NCF0=-12000元
NCF1=3800元 NCF2=3560元 NCF3=3320元
NCF4=3080元 NCF5=4840元
回收期=3+1200/3080=3.43（年）
平均报酬率=[（3800+3560+3320+3080+4840）/5]/12000=31%
6、每年净营业现金流量=2040万元
投资回收期=6500/2040=3.2（年）
NPV=[2040X（P/A,10%,5）+500X(1+10%)-5]X(1+10%)-3-
[500X(1+10%)-3+2000X(P/A,10%,2)+2000]=2187.9(万元)
第四次财务管理作业答案
1、Q=(2X16X0.04/0.9%)1/2=11.9(万元)
次数=16/11.9=1.34（次）
2、Q=(2X4000X800/10)1/2=800(件)
年度生产成本总额=10000+(2X4000X800X10)1/2=18000（元）
3、P=[2.662X（1+15%）/(15%-5%)]X(1+15%)-3
+2.662X(1+15%)-3+2.42X(1+15%)-2+2.2X(1+15%)-1=28.87（元）
4、P=1000X(1+10%)-5+80X(P/A,10%,5)=1000X0.621+80X3.791
=924.3(元)
结论：不值得购买。
5、1）Rf=8%，市场平均风险报酬率=15%-8%=7%
k=8%+2X7%=22%
2）P=1X(10%+1)/(22%-10%)=9.17(元/股)
6、1）年末流动负债=270÷3=90（万元）
2）存货的年末数=270-90X1.5=135（万元）
平均存货=（145+135）/2=140(万元)
3）主营业务成本=4X140=560（万元）
4）年末速动资产=1.5X90=135（万元）也就是应收账款的余额
应收账款平均数=（125+135）/2=130（万元）
应收账款的周转期=360/(960/130)=48.8(天)
