In recent years, tourism has been popular and played an important role in our nation’s economic growth. However, I am afraid that if tourism develops over, it will bring harm to the environment and give rise to many problems.
There are a few reasons accounting for my views and I would like to list three of them. One of the examples is that a large number of woods and other plants were replaced by all kinds of accommodation facilities or scenic spots. That definitely breaks the ecological balance of these areas and destroys the natural beauty of the scenic spots. Worse still, more pressure has been placed environment protection in that many tourists left their garbage in the scenic spots. In addition, over-developed tourism will occupy large numbers of farmland and lead to the shortage of the land.
In a word, tourism will be harmful to our environment if it is over development. Thus, I do not advocate that we development tourism without considering the environment. And we should keep the balance between tourism development and environment protection so that we can achieve the sustainable development between our nation’s economy and the environment.
Dear Headmaster,
I'm writing to tell you about the discussion we've had on whether the school should organize a spring outing for the students.
Opinions on the question are pided as follows:70% of the students think that the school should organize the spring outing. They believe that the spring outing can make them enjoy the nature's beautiful scenery, which can broaden our vision and fill us with more knowledge. They also say that the air in the open fields is fresher. What's more, fresh air does a lot of good to our health.
On the other hand,30% don't like the idea of going out for a spring outing. In their opinions, time is very precious, so they have to grasp every minute to work hard at their lessons. Traveling costs a lot. In that case, it will add to their families' burden. Above all, no one can be sure of the safety of every student.
Yours truly
Li Hua
尊敬的校长,
我写信告诉你关于学校是否应该组织一次春季郊游的讨论。
对问题的看法有如下:70%的学生认为学校应该组织“春季郊游”。他们认为,春季郊游可以使他们享受大自然的美丽的风景,它可以扩大我们的视野,使我们更多的知识。他们还说,在空旷的.田野的空气很清新。更新鲜的空气对我们的健康有很大的健康。
另一方面,30%不喜欢外出郊游的想法。在他们的观点中,时间是非常宝贵的,所以他们要抓紧每一分的努力,在他们的课程中努力学习。旅游成本很多。在这种情况下,它会增加他们家庭的负担。首先,没有人能确保每个学生的安全。
你真正的
李华
This summer my sister and I follow my mother to travel to the United States, we went to the three cities and one island, San Francisco, Los Angeles, Las Vegas, and Hawaii.
Hawaii is my favorite, although only two days, but I went to the beach for several times, is the famous waikiki beach, listening to the tour guide said where the sand came from Australia, where the water is clear, the sand is very clean, when I was in the sea waves to see the small fish, I also into base sand castle on the sand beach, made apple mould sand, crabs, bottle gourd, the shape of a fish, I also want to go to the seaside.
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.
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.
When holiday comes, thousands of people pour into the tourist sites, they want to relax themselves and enjoy the beautiful scenery. But Chinese people have a bad habit, they like to leave some notes on the site, proving them have been here before. Such a behavior has been criticized by the public, because the leaving note will damage the preservation of the tourist site. Most of the tourist sites are part of our country's historical relics, these sites are priceless, it is everyone's duty to protect the sites. When we go to travel, we should behave ourselves. First, we need to have the idea that no rubbish being leaved behind when we leave the site. We should take away what we bring, keep the environment clean. Second, no any notes being written in the sites. Though in the old days, Chinese workers like to leave their names on the sites, but now it is a new world, we need to behave ourselves.
一、论文发表出来毕竟是给大众看的,所以首先要能算得上一篇文章。在表现形式上要注意:
1.文章中出现的语法错误,拼写错误,逻辑错误都是要避免的。英文论文中要注意单复数,时态语态,和表达习惯,不能简单的将中文翻译为英文。一般写完后不要盲目认为自己就没有小错误,让别人检查下语法错误是必要的。
2.文章中如果有插图,请大家格外注意要美观,要简洁,要直奔主题,让人一眼看到论文的动机。这里是很多人不屑一顾的地方,认为论文实验数据给一个表格或者什么什么就行了,其实不然,
论文的插图有多种,放在引言中的插图,能让读者或者审稿人能够直接明白你想要表达什么,你想要做什么事情,而不用读大片的引言。比如:随着***的发展,***带来了**这类的废话。当然并不是说你的引言不重要,
引言是让读者和审稿人感兴趣的源头,所以一定要逻辑性强,一定要恰当得说明我们方法的由来。插图一般建议用VISO来画,多参考优秀论文的插图画法,如果你肯下功夫,你可以做一个web页面出来展现,这样一个demo
能为你加分不少。
3.文章中有表格的话,一定要按照标准会议论文格式的表格来绘制。一般word2013足够了,线的粗细,边框一定要合适。
4.文章的结构一般有 摘要,引言,相关工作,方法/模型介绍,实验数据,实验结果,总结这几部分。这些结构层次一定要清晰,以读者能最快接受为好。
二、再美观的外表都需要详实的内容作为主体,所以在内容上要注意以下几点:
1.实验数据:
首先,实验数据一定要足够,能够撑得起你要做的实验,或者圈内大家公认的标准;好点的文章都要求至少在俩个数据集上进行过测试。
其次,实验数据一定要有完备性,正面样本和负面样本要均衡,要分训练数据和测试数据,训练用60-80%,测试用20-40%, 也可以用五倍或者十倍交叉验证;
最后,实验数据 最好是公开数据集,你可以建立自己的数据集(写论文的时候也能作为一种贡献)但是公开数据集方便大家测试和实验,更能体现自己方法的优劣;
2.实验对比:
首先,实验对比方法不能只有一个俩个,最好能够有自己方法相关的四到五个方法作对比,对比方法不能太过时,一般是常用的方法 和最新提出已经公开发表的方法;
当然和好的算法相比,我们也要灵活,你能确保比最优秀的算法效果还好么?如果不能,走走捷径,测试数据去去噪声对比方法条件苛刻一点;
其次,实验对比一定要全面,从时间和空间复杂度,效率,精度,召回率,误差(RMSE,MAE等)等多个指标进行对比。具体可以参阅其他优秀论文中的指标;
最后,实验对比结果展示一定要花功夫,不要一句话强调我的方法好,要花式呈献给读者:表格+曲线+分布图等方式 或者针对论文中读者关心的问题不同视角 的呈现方式。
3.实验结论:
总结的时候不要一句话说死,说我们的方法是最好的之类。一定要说明自己的实验环境:用了什么型号计算机,cpu,内存,线程等,还有做实验时的参数等;这也是实事求是的科研态度的体现。
除此外,我们还要总结我们方法的缺点,按照实际情况说明缺点,方便别人改进,审稿人的火眼精金,你骗不了他的。当然不要刻意说,这样显得对自己方法不自信。谈及三分即可。
三、论文的标题,摘要,引言, 相关工作和参考文献怎么写呢?
1.论文标题:
标题是论文的眼睛,如果标题太大或太冗余 ,那么基本上你的论文没戏了。为什么这么说?首先标题就能看出来你文章侧重想解决的问题,如果标题上是常见问题的解决,那么人家肯定会想
这方面有哪些好的论文,如果你超不了它们,那我凭什么要录用你的呢?如果你起的名字很新颖,那么读者和审稿人很愿意读下去,一探究竟。标题一定要信息量大,体现论文解决问题的侧重,
而且要简洁,少用介词 多用动词,紧贴热门前沿的话题或者科研名词。标题长度最好在10个单词之内。
2.论文摘要:
有了好的标题,摘要也不能差,摘要相当于论文内容的总体概览,这里让人得看到你的贡献,比如:我们通过***方法解决了***问题,最好2-3个以上的贡献。此外,描述上一定要有逻辑。
当下有哪些挑战,常用的解决办法,他们做的效果怎么样,我来做了这件事,能够解决哪些问题。我们的方法模型是什么,考虑了哪些元素,做了哪些重要的训练和测试等,最好简单说下我们获得了一定效果。
3.论文引言:
引言说什么?说废话么,当然不是。说我们写下这篇文章的动机,也叫motivation。文章的动机是将读者和审稿人带入论文环境的一个重要手段。看一篇文章不一定上来就说公式,那样谁都不会感兴趣。论文的动机简单的可以这样来写:当下紧贴生活中我们问题的体现,比如社交网络中的商品推荐问题,我们就可以将实例定位在日常我们上淘宝或者定外卖这些例子上。这样做的好处是,别人容易建立一个实践中的模型映像。然后,我们要引导读者。我们在买外卖或者买商品遇到了哪些问题?商品太多怎么选择?没有我想要的`怎么办?然后我们利用什么能解决呢? 我们想到了协同滤波,他可以根据你的历史记录和其他人的购买记录来帮助你选择商品,你以前买过,说明你的兴趣在这一方面,你的好朋友买过,你们可能有共同的兴趣。这就是引导。然后读者自然而然就对协同滤波有了理解。我们介绍我们的方法同样是这样的一个过程。为了更方便读者进入环境,我们可以上插图,插图的意义可以是美观,也可以是代表你的大段文字。这是一个加分项,但是不要图文不搭配 这样就不好了。引言说上一大段后,可能读者已经有了大体的概念,然后我们要稍微讲下我们模型或者方法的新颖性和部分细节了,我们可以讲协同滤波的大体原理,然后再重申我们的贡献,至此引言完毕。
4.相关工作
相关工作就是专门介绍你对比方法的地方。一般都不是很详细介绍,不然别人的工作说了半天,自己的反而不是主角了。别人的工作一般介绍3个左右就可以了。简单的原理描述和必要的公式介绍。
5.论文 参考文献
参考文献在很多人眼中不值一提,我文章都写完了,参考文献随便放几篇就好了。偏偏不是,正所谓细节决定成败,千里之提溃在蚁穴。参考文献说明了你论文的档次,你参考的文献价值高,说明你是在吸取精华,在进行提高。你参考的都是旧的,简单的方法,那么你的文章估计也就在这个水准了吧。参考文献要求:相关,经典,新颖,高质量。具体来说就是,我们要引的文章一定是那些近几年内牛逼会议或者期刊中相关的论文。参考文献由于出自多个地方,所以一定要注意统一格式,论文作者,标题,会议名称,地点,时间,页码等 顺序一致,标点一致。参考文献一般是相关的放在最前面,不太相关的和质量稍差的放后面。一般4页的短文,5-10篇参考文献就好了,6-8页的中长度文章20篇参考文献足够,10页以上双栏的大会议或者期刊论文 一般30-60篇参考文献。
四、论文的包装和投稿
论文算是写完了,该拍卖了。怎么包装论文呢?首先,要让别人(最好是学术圈内英语好的人士)帮你看看 改改简单的语法和排版,确保格式正确,论文美观整齐。然后,让老师或者大牛帮你看看框架有没有问题,问题是否描述清楚,模型是否合理?评估下你的文章是什么等级,可以估计是会议普通呢还是高质量的期刊呢?期刊投稿周期长,审稿慢,一般第一次反馈意见最快也得2个月以上,意见回来修改一俩个月再投出去再改,一来二去,最快也得大半年以上才能录用,出版得几个月后了。遇到坏的结果,你的论文估计不是改一改那么简单了,你可能得修改框架和对文章进行实验补充了,你还得考虑下是否继续投这个期刊,还是换另外一个。会议论文审稿就快了,一般三个月意见都出来了,而且一般说录用就录用,修改较少。投稿不能一稿多投,不能重复度过高,所以投稿前需要做个检测。投稿最好找圈内熟悉的人推荐,靠人脉在哪里都是行得通的,同样的水平,谁的靠山多谁就赢了。
