篇1：有关公园英文
全文共 1325 字
+ 加入清单Every city has many theme parks, the local people like to go to the park for a walk or take some exercise. In China, most parks are free, people can go there without charge, but still some other parks need to charge. People urge that all the parks should be free, while I think it will do harm to the park.
每个城市都有很多主题公园，本地人喜欢去公园散步或者锻炼。在中国，大部分公园免费，人们无需给钱就可以进入公园，但是仍然有一些公园需要付费。人们要求所有的公园应该免费，然而我觉得这样会对公园有害。
One the one hand, opening the parks for free encourages people to go to the park for entertainment. Most people have the habit to take a walk after dinner, so it can help them to keep their bodies healthy. The children can have fun with their friends, too. The parks provide people so much fun, so it is good for people to go to there for free.
一方面，免费开放公园鼓励着人们去公园娱乐。很多人有饭后散步的习惯，这样有助于让他们保持身体的健康。孩子们也可以和他们的朋友找乐子。公园给人们提供了很多的乐趣，因此免费开放公园对人们是有好处的。
On the other hand, too many people go to the parks will do harm to the environment. Some people will throw away their trash away, the environment will be polluted. What’s more, the crowed people will make people have less space for them to have fun.
另一方面，过多的人去公园会对环境造成伤害。一些人会随处扔垃圾环境会被污染。而且，成群的人会让人们享有很少的空间来娱乐。
For me, I think it is not good to open the parks for free, it needs to control the number of people, so we can protect the environment.
对于我来说，我觉得免费开放公园是不好的，要控制人群的数量，这样我们才能保护环境。

+ 加入清单Viewing vs.Reading
The pace of reading, clearly,depends entirely upon the reader. He may read
as slowly or as rapidly as he can or wishes to read. If he does not understand
something, he may stop and reread it, or go in search of elucidation before
continuing.
The reader can accelerate his pace when the material is easy or less
than interesting, and slow down when it is difficult or absorbing.
If what he
reads is moving, he can put down the book for a few moments and cope with his
emotions without fear of losing anything.

参考译文：
自从地球上有了人类以后，我们在不断地发展进化的同时也在不断的伤害着那些可爱的动物们.他们没有过错,他们只是根据自然界的法则和平的生活着.可是自从有了人类的存在,他们的家园变的越来越小.有些动物甚至已经灭绝了.
在灭绝的动物里，袋狼算是最惨的了。在很久以前袋狼生活在广阔的大草原上，它们过的很快活，无忧无虑。自从人类的到来改变了它们的生活。由于人类的大量圈地，饲养牲畜使得绿草变地越来越少，许多食草动物迁徙到别的草原上。这样以草食性动物为食的袋狼就没有了食物。它们便去偷人类饲养的动物。农场主便痛恨起了袋狼，见一个杀一个，就这样最后一只野生袋狼也被杀死了。当人们意识到袋狼就要灭绝时，才开始保护公园里的最后一只袋狼，这只袋狼才过了最后48天的好日子。而48天后，袋狼永远的从地球上消失了，永远的！
当然不是所有灭绝的动物都是人类杀死,有的是不适应环境的变化而灭绝的.但是某些动物的灭绝，人类有着不可推卸的责任。人类自古以来就一直残忍地对待着那些动物们,人类剥夺了它们生活的权利.
现在人们似乎还没有意识到一种动物的灭绝的危害。为了赚钱人什么都愿意做，他们把动物的皮毛卖到商场，把动物的肉卖到餐馆。但是我们不能把一切责任都推卸到商贩的头上，消费者也有责任，如果没有消费者的需求那么商贩也不会铤而走险。人类还在吃着野生动物。比如：蛇。如果蛇灭绝了，老鼠会大肆繁殖，到那时候我们该怎么办……
因此每一种生物都有它存在的意义，它们都在以自然的法则生存。如果生物链的一头断了，那么另一种动物就会大肆繁殖，甚至威胁到人类，大家记住保护动物。保护动物就是保护人类自己！

亲爱的周老师，
How time flies! It has been a few years since I left high school, but I still remember you in my heart, because you’re the best teacher in my mind. It’s not only because you taught me knowledge, but also you taught me how to study. I have really benefitted a lot from you. So I would like to express my great thanks to you, and share my life in college with you.
时间飞逝!我高中毕业已经几年了，但我仍然把你记在我的心里，因为你是我心目中最好的老师。这不仅是因为你教与我知识，而且你还教我如何学习。从你身上我真的获益匪浅。所以我想向你表达我的感谢，并与你分享我的大学生活。
Now I’m studying in Hunan First Normal College, which is Chairman Mao’s former school. I major in English, because I find it so fun and interesting. As far as I’m concerned, our English Department is the best department in our college. The teachers in our department are knowledgeable, experienced, and warm-hearted. And my classmates are nice, friendly and helpful. Thus, I have a good atmosphere to study. When I have difficulties in study, I always ask my teachers for help or discuss with my classmates. Through their help, I have made great progress in my English study.
我现在在湖南第一师范学校学习，这是主席之前呆过的学校。我的专业是英语，因为我觉得它很有趣。我觉得我们英语系是我校最好的学部。我们系的老师知识渊博，经验丰富，热心肠。我的同学们也很和蔼，友好，乐于助人。因此，我拥有一个很好的学习氛围。当我在学习上遇到困难时，我总是向我的老师寻求帮助或与同学讨论。在他们的帮助下，我在英语学习上取得了很大的进步。
College life is much different from high school life. In college, we should acquire knowledge as well as improve our integrated abilities. There are a lot of English classes for us to learn, such as Basic English, Oral English, Listening, Reading, Writing, Translation, Grammar, English Literature, and so on. I enjoy these classes very much. Except English, we have many other subjects to learn. Life seems so busy here but it’s so fruitful for me.
大学生活与高中生活有很大的不同。在大学，我们要获取知识也要提高我们的综合能力。我们要上很多的英语课，比如，基础英语，英语口语，听力阅读，写作，翻译，语法，英语文学等。我非常喜欢这些课。除英语外，我们还要学习很多其他科目。在这里生活是如此的忙碌，但这对我来说是如此丰硕的收获。
After class, I usually go to the English Corner. There I can practice my oral English by talking with foreigners or chatting with my schoolmates. Now, I’m able to communicate with foreigners well. Sometimes I also take part in some social activities. For instance, last weekend I attended an interesting play. As it was my first performance, I felt a little nervous at the beginning. But when I appeared on the stage, I made every audience laugh happily. I was so proud of myself at that moment, because this was my first achievement.
下课后，我经常去英语角。在那里我可以通过与外国人或我的同学聊天来练习我的英语口语。现在我可以很好的和外国人交流了。有时候我也可以参加一些社交活动。例如，上周我参加了一个有趣的表演。因为是我第一次表演，所以一开始的时候我觉得有点紧张。但当我出现在舞台上时，我让每一个观众都开心的笑了。在那一刻，我为我自己感到骄傲，因为这是我的第一个收获。
What about your present life? I hope to hear from you soon.
你目前生活怎么样呢?希望很快能收到你的回信。
At last, I hope everything goes well with you. Please give my best regards to your family.
最后，我希望你一切顺利。请代我向你的家人问好。
Sincerely yours,

篇19：如何判定过渡句的存在，对文章结构的好处
全文共 431 字
+ 加入清单无论是承上、还是启下，抑或是承上启下，带来的好处都是使文章的结构严谨。
例如： 为什么我国的石拱桥会有这样光辉的成就呢？首先，在于我国劳动人民的勤劳和智慧。他们制作石料的工艺极 其精巧，能把石料切成整块大石碑，又能把石块雕刻成各中形象。在建筑技术上有很多创造，在起重吊装方面更有意想不到的办法。如福建漳州的江东桥，修建于八 百年前，有的石梁一块就有二百来吨重，究竟是怎样安装上去的，至今还不完全知道。其次，我国石拱桥的设计有优良传统，建成的桥，用料省，结构巧，强度高。 再其次，我国富有建筑用的各种石料，便于就地取材，这也为修造石桥提供了有利条件。
文中这个划线句子就是针对过渡句的结构作用出的试题。“这样辉煌的成就”概括了上文赵州桥的历史、结构、造型特点，具有承上作用，“为什么”这个疑问代词，概括了这一段的主要内容，所以具有启下的作用。
综上所述，在这个段落中，划线句子的作用就是：承上启下，上承接我国石拱桥取得的辉煌成就，下引出取得成就的原因，使文章架构严谨。
篇20：民俗文化英文
全文共 2149 字
+ 加入清单A folk culture is a small isolated， cohesive， conservative， nearly self-sufficient group that is homogeneous in custom and race with a strong family or clan structure and highly developed rituals. Order is maintained through sanctions based in the religion or family and interpersonal. Relationships are strong. Tradition is paramount， and change comes infrequently and slowly. There is relatively little division of labor into specialized duties. Rather， each person is expected to perform a great variety of tasks， though duties may differ between the sexes. Most goods are handmade and subsistence economy prevails. Individualism is weakly developed in folk cultures as are social classes. Unaltered folk cultures no longer exist in industrialized countries such as the United States and Canada. Perhaps the nearest modern equivalent in Anglo America is the Amish， a German American farming sect that largely renounces the products and labor saving devices of the industrial age. In Amish areas， horse drawn buggies still serve as a local transportation device and the faithful are not permitted to own automobiles. The Amish＇s central religious concept of Demut "humility"， clearly reflects the weakness of individualism and social class so typical of folk cultures and there is a corresponding strength of Amish group identity. Rarely do the Amish marry outside their sect. The religion， a variety of the Mennonite faith， provides the principal mechanism for maintaining order.
By contrast a popular culture is a large heterogeneous group often highly individualistic and a pronounced many specialized professions. Secular institutions of control such as the police and army take the place of religion and family in maintaining order， and a money-based economy prevails. Because of these contrasts， "popular" may be viewed as clearly different from "folk". The popular is replacing the folk in industrialized countries and in many developing nations. Folk-made objects give way to their popular equivalent， usually because the popular item is more quickly or cheaply produced， is easier or time saving to use or leads more prestige to the owner.
