In recent years, tourism has developed rapidly in China. Many people believe that tourism produce positive effects on economic growth and we should try our best to promote tourism. But what these people fail to see is that tourism may bring about a disastrous impact on our environment. As for me, I\'m firmly convinced that too much tourists bring harm to the environment.

The bad impact of tourism on the environment has mainly expressed itself in various ways. One way is the proceof exploiting a new scenic spot. In order to attract tourists, a lot of artificial facilities have been built, which have certain unfavorable effects on the environment. This proceusually breaks the ecological balance of the area. In some mountainous places, trees are being cut down to build hotels for others to see and explore the beauty of the mountains. Then land slides and mud-rock flows come up. Another way the development of tourism has damaged the environment occurs when tourists go to scenic spots. Some tourists don\'t have the awareneto protect the environment, and ignorantly throw their garbage here and there. Some people even kill the local wildlife to eat, which badly damages the balance of the natural environment.

It is wrong to sacrifice the environment for the growth of tourism. We must keep in mind that too much tourists bring harm to the environment. We need to find a balance between satisfying the needs of tourists and reducing to a minimum the pollution they cause.

Will Tourism Bring Harm to the Environment? Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world. In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagernefor a glimpse of ages past . Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air. In sum , although tourism is playing an indispensable we`d better try to limit role in the society , I still believe that its speed according to the harm that brings to the environment.

The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.

Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of \"sustainable development\", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.

What\' s more, every citizen should realize the seriousneof the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.

经过了为期两天的统计学实验,主要通过EXCEL这个软件来完成这次的实验。

首先掌握用EXCEL进行数据的搜集整理和显示,要求熟练运用EXCEL搜集数据,统计分组,制作统计图。这是最基础的操作,让我们首先对EXCEL有一个初步的了解和认识。

实验二是用EXCEL计算描述统计量,可以运用函数描述统计量。要求我们掌握基础的常用的函数对数据进行初步归纳,了解统计学中最常用的函数组成。实验三用EXCEL进行时间序列分析。首先是测定增长量和平均增长量,然后计算出长期趋势。得出我们所要统计的结果的一个预计变动趋势。让调研人员有一个机动的应变对策。这个实验特别主义对时间序列的把握,常常会搞错要除去的年数。这在实验中常常出错。

实验四用EXCEL进行指数分析,指数分析是统计学中最主要的一个数据分析。先计算出总指数,再得出平均指数,最后进行因素分析。其中平均数是通过加权算数平均法得来的。

实验五是用EXCEL进行相关与回归分析。用EXCEL进行相关分析有两种方法,一是利用相关系数函数,在EXCEL中,提供了两个计算两个变量之间相关系数的方法,CORREL函数和PERSON函数,这两个函数是等价的,实验中我运用了用CORREL函数计算相关系数来进行对数据的分析。另一种是利用相关分析宏。EXCEL进行回归分析同样分函数和回归分析宏两种形式,其提供了9个函数用于建立回归模型和预测。这9个函数分别是:INTERCEPT返回线性回归模型的截距、SLOPE返回线性回归模型的斜率、RSQ返回线性回归模型的判定系数、FORECAST返回一元线性回归模型的预测值、STEYX计算估计的标准误、TREND计算线性回归线的趋势值、GROWTH返回指数曲线的趋势值、LINEST返回线性回归模型的参数、LOGEST返回指数曲线模型的参数。在实验过程中我使用的是回归分析宏进行回归分析。

实验六是用EXCEL进行预测。主要有移动平均法、指数平滑法、趋势预测法。在实验过程中分别对这三种方法进行了尝试。都得到了预期的结果。实验七是用EXCEL进行参数估计和假设检验。主要掌握了解Z检验的操作步骤。

通过这次实验让我对统计学的知识框架有了更深一步的了解,并知道通几种常见的基础的方法,对搜集的资料进行数据归纳,抽样分析,并进行预测,对比这个统计学的过程有了进一步的掌握。在今后的学习生活中,希望可以通过这次学习到的方法和知识,可以对自己所研究的领域,进行进一步的调研,分析,使数据更趋于有用化,可操作化,尽量减少数据的赘余与资源的浪费。学习了统计学就要将之灵活运用于实际的生活中去,让知识造福于人类,让知识拥有自己的生命了。

st summer holiday, I took a trip to Yunnan. It is in the southern part of our country .It is really a very beautiful place grand mountains, clean rivers and kind people. Trees and flowers are seen everywhere. Every year there are lots and lots of visitors.Maybe you have heard about Shi Lin (stone forests. There are all kinds of strange stones. Some of the small stones look like graceful girls; and the big stones look like handsome men. Other stones look like cats, peafowls, double-edged swords, mice,

elephants and so on. Of all the stones, the stone like a beautiful girl in a legend is the most famous .Its name is A Shima.

I also went to Li Jiang. The roads in that city are just like the Eight Diagrams. Any road in the city goes to the center of Li Jiang. A river runs through the whole city. If you go along the river, you\'ll never get lost. There are many ethnic minority people in Yunnan. They are very cordial. And they all like singing and dancing. We danced with them around the campfire that night. I really had a good time.

I like the elephants and fruits there best. An elephant is even taller than me! I even mounted the elephant, though I was very afraid at first. But the elephant seemed very friendly. I took some photos with it. The fruits there are very fresh and delicious. They are very good for our health.

The trip to Yunnan impressed me GREatly. I will never forget it.

严厉:50%

我的班主任老师真是多变,常常会对我们“雷电交加”。有一次,老师发了一张卷子,让我们改,改好后交。老师接过我们的卷子一张张认真地检查,不断点头,脸上时不时阳光灿烂,突然,老师紧盯着一张卷子皱起了眉头,脸阴了下来。看到了老师这张“晴转雷阵雨”的脸谱,我开始暗暗祈祷:天哪,不是我的,不是我的……继而,老师无比严厉地喊道:“荀英铭,过来,这道题你怎没改……墙角站着去。”我们无比同情那位站墙角同学,也暗自庆幸多亏好好改卷了,要不是绝对逃不过我们老师的“火眼金睛”的。

温和:23%

“咣当!”我在操场上马失前蹄,摔了个大跟头,无比郁闷地坐在地上,撩起裤腿,揉着磕破皮,冒出血丝的`膝盖。“怎么了,别用手碰,会感染的。”传来老师的声音,不远处老师正向我这跑来,“走,到我办公室,我给你包一下。”老师一边搀扶我起来,一边说,一改严厉的常态,关爱之情溢于言表,我感到一股暖流涌进了心里,眼睛也潮湿了,原来我的老师也有这么温和的一面,她严厉的外衣下面是对我们深深的爱呀。

幽默:27%

某天我写卷子的时候,把贝多芬写成了贝多花,恰巧被老师看到了,她没生气居然幽了我一默:“你把人家的名字写错了,一会贝老爷子举着钢琴从坟墓里出来找你算账。”为这,全班同学笑了个没完没了,老师还时不时拿“贝花”说事,提醒我们千万要认真,千万别马虎。

这就是我的老师,严厉多点,有点温和,有点幽默。

8月1日,我们一行人乘坐春秋航班,来到了梦寐以求的海滨城市──青岛。那是一座依山傍水的美丽山城,那里有一望无际的海水浴场,有风景秀丽的崂山,还有精巧别致的红瓦绿树,真不愧为避暑度假的好地方。

我们先来到闻名的“海上名山”的崂山。我们的车行驶在崂山的盘山公路上,窗外群峰耸立,山海相接;山脚下海浪阵阵,波涛滚滚。我感到像到了人间仙境一样,令人心旷神怡。

登山了,我们沿着山路往上爬。不久,一排瀑布骤然出现在眼前,那瀑布就像巨龙飞腾,气势磅礴。这就是著名的“龙潭瀑布”,果真名不虚传,那宏伟的`气势就像“飞流直下三千尺”般壮丽。

第二天,我们来到了海滨浴场冲浪。青岛的海边美丽极了:天是一片蓝玉,海是一块翡翠,远望水天相连,蔚为壮观。我们踩在细软的沙滩上,奔向那向往已久的大海。

大海卷起一层层美丽的浪花,呼啸着向沙滩打来,一眨眼它又逃了回去,就像一群顽皮的孩子打闹着。这时,一个一米多高的大浪拥上来,我赶紧把身体背过去,一浪过去了,我就向前走几步。不一会儿,又一排大浪冲来,我赶紧往回跑……我们在海浪声中相互扑打嬉戏,绿海碧波留下了我们欢乐的笑声,那感觉正是爽极了。

青岛之旅给我留下了深刻的印象,要开学了,我多希望能有一个像去旅游那样快乐的新的开始啊!

In August 1st, we took a spring and autumn flight to the coveted coastal city of Qingdao. It is a beautiful mountain, where there are endless beach, a beautiful scenery of Laoshan, there are exquisite red trees, really is a good place for summer vacation.

We first come to the famous \"famous mountain\" in Laoshan. We were driving in the Laoshan mountain road, mountain peaks standing outside the window, the sky; at the foot of the mountain waves blowing and billowing waves. I felt like I was in the fairyland of the world, and I was delightful.

Mountaineering, we climbed up the mountain road. Soon, a row falls suddenly appeared in front of the waterfall like dragon soar, of great momentum. This is the famous \"Longtan waterfall\", the magnificent momentum really wonders, like \"waterfalls three thousand feet\" magnificent.

On the second day, we came to the beach and surf. The sea of Qingdao very beautiful: the sky is a turquoise sea, is a piece of jade, Yuanwang spectacular water. We stepped in the soft beach, toward the long sea.

The sea rolled up a layer of beautiful waves and whistled to the beach. In the blink of an eye it fled back like a naughty child. At this time, a one meter high waves hold up, I quickly put the body back in the past, a wave of the past, I will walk a few steps forward. In a few moments, another row of waves rushed, and I ran back... We in the sound of the waves in the sea waves play each other furiously, leaving our laughter, the feeling is very good.

The trip to Qingdao left a deep impression on me. To start school, I wish I could have a new start like going to travel.
