近三年,这个县的粮食总产量,以平均每年递增百分之二十的速度发展

解题思路：首先结合条形图和折线图求出三年各自的利润率，利润率=[利润/资金投放总额]×100%，再求出三年的利润率=[三年的总利润/三年的总资金投放总额]×100%，即可得到正确答案．

2007年的利润率=[30/200]×100%=15%，
2006年的利润率=[10/100]×100%=10%，
2008年的利润率=[50/250]×100%=20%，
∴2007年的利润率比2006年的利润率高5%正确；
2008年的利润率比2007年的利润率高5%正确；
三年利润率=[10+30+50/100+200+250]×100%≈16%，
∴这三年的利润率为15%错误；
∵20%＞15%＞10%，
∴这三年中2008年的利润率最高正确．
故正确的结论有3个．
故选C．

本题考点： 折线统计图；条形统计图．

考点点评： 此题主要考查了看折线图与条形图，解题的关键是根据条件正确计算出三年各自的利润率，再进行比较即可．

只能这样了
设一年定期,三年后利息为x元 20000+[20000+(20000+20000*1.98%*80%)*1.98%*80%]*1.98%*80%=x
x=自己算吧
设三年定期,三年后利息为y元 20000*2.52%*3*(1-20%)=y
y=1209.6

这个题不用方程就可以
一年定期,三年后利息为 20000*1.98%*3*(1-20%)=950.4元
三年定期,三年后利息为 20000*2.52%*3*(1-20%)=1209.6元

y=2^x/10

I am going to graduate from senior grade 3.In front of me,there are many choices.I think I am a frank,open-minded,and optimistic person who is following the social trend.Also I am good at oral English in which I can communicate with the other people,especially with foreign people.Meanwhile,I am very flexible and active in doing everything. According to my personality,I am sure that I am qualified for an air-hostess or something alike.That is why I want to go to a school which is related to the airo-transportation.Certainly,I think,perhaps,being an air-hostess is a beautiful dream for most of the girls.So I am going to face with great pressure coming from the graduates of my age. But,I will try my best to prepare for this.And I am sure I will make it.

A“产量”“发展”主谓搭配不当。B去“等”。C“正确贯彻-”与“深刻理解”调换顺序。

第一年节余：（1650+1550-1500）*12=20400；
第一年节余：（2000+1850-1830）*12=24240；
第一年节余：（2550+2320-2230）*12=31680；
20400+24240+31680=76320；
答：3年中,王明家一共可以节余76320元；
76320+76320*4.25%*3=86050.8；
答：如果2012年底把这笔钱存入银行,3年后可以从银行取回86050.8元.

因为环比发展速度的乘积开n次方等于几何平均发展速度,而发展速度减一等于增长速度,所以,上述题的答案是三年几何平均发展速度8.9878%
(1+7%)(1+9%)(1+11%)^(1/3)=8.9878%

三年利润平均增长率是依据企业本年利润总额与三年前年末利润总额计算出三年利润平均增长率,用以评价企业综合发展能力.
三年利润平均增长率设计的原意是为了均衡计算企业的三年平均利润增长水平,从而客观评价企业的发展能力状况.但从该项指标的计算公式来看,则不能实现上述目的.该指标的计算结果只与企业本年度实现利润总额和三年前年度实现利润总额有关,中间两年的实现利润总额大小不影响该指标计算结果.
三年利润平均增长率＝[（年末利润总额/三年前年末利润总额)∧1 / 3 －1]×100%
预估三年后的利润=当前年度利润*三年利润增长率∧3

the average sales volume in last three years

解题思路：由已知中，某企业近三年的产值连续增长，这三年的增长率分别为x，y，z，我们可以设出这三年平均增长率为P，进而构造出关于P的方程，解方程即可求出这三年平均增长率．

设这三年平均增长率为P，
则（1+P）³=（1+x）（1+y）（1+z）
故P=
3(1+x)(1+y)(1+z)
−1
故选D

点评：
本题考点： 指数函数的实际应用．

考点点评： 本题考查的知识点是函数模型的选择与应用，其中增长率问题是指数函数模型最常用的应用，函数值Y=A（1+P）x，（其中A是基数，P是增长率，x为期数）是最常的函数模型．

Hello, everyone!
It’s nice to speak about what we can do for our school, and I think each of us can do something.
The first thing we can do is to protect the facilities in our school. When we leave the classroom, we should never forget to turn off the light or close the door. We should not leave the tap water running or waste any materials in the laboratory class.
The second thing we can do is to make our campus more beautiful. Every one of us may plant a tree in the school or organize a cleaning on the campus. And equally importantly, we should develop a good habit of not littering about.
At this moment, I think our duty is to put all our efforts into study not just for our school, but also for our future.
If everyone does his best for our school, I believe our school will soon take on a new look, and become a better place to study and live in.
Thanks for listening!

解题思路：根据近似数的精确度求解．

2.4×10⁵精确到万位．
故答案为万．

点评：
本题考点： 近似数和有效数字．

考点点评： 本题考查了近似数和有效数字：经过四舍五入得到的数称为近似数；从一个近似数左边第一个不为0的数数起到这个数完，所以这些数字都叫这个近似数的有效数字．

I’m in senior three this year. With the college entrance examination approaching, all the teachers and students are engaged in preparing for the important exam.
First of all, all of our teachers are devoted to giving us lessons, in their free time, they will sacrifice their rest for us.So grateful are we that we determine to try our best to study.
As for our students, most of us spare no efforts to study.Some of them even stay up late into deep night, which makes them feel sleepy in class. I am so worried about them that I suggest our teachers give us more time to relax in the hope that we can have more energy to study.


这篇作文主要写清楚老师学生对高考做的准备工作，说明老师对学生的认真，学生的努力，用一般现在时，同时应该对现象提出解决办法。写作时要用一些固定结构，象with the college entrance examination approaching, are engaged in preparing for ，are devoted to giving us lessons some of them even stay up late into deep night, which makes them feel sleepy in class. Some of them even stay up late into deep night, which makes them feel sleepy in class.这句话是非限制性定语从句。
