关于火车发展历程的英语作文【一】
1.1 水利水电工程对气候的影响
区域性气候是由大气环境和水体分布决定的，大气环境和水体分布在自然状态下是平衡的，然而，在人类修建水库和灌溉工程后，或多或少地会对水体的分布造成影响。水是构成大气环境的重要因素，正是因为水循环过程才有了气候的千变万化，水体分布的改变打破了原有的平衡，造成了气候的无法调控甚至灾难气候。
1.2 水利水电工程对降雨的影响
水利水电工程的不断建造会使水库不断增多。经过阳光的照射，降雨量会大大增加，大量的降雨对于部分区域是“甘露”，对于部分区域却会引起洪涝灾害。据调查发现，地势高的迎风面降雨会增加，反之降雨会减少，即在距离水库比较近的地方，降水量反而会下降。水利水电工程的建立原本是为推动当地经济发展，现在看来，似乎有些顾此失彼。长此以往，降雨时间分布也发生了变化，比如南方的大型水库的夏季降雨量就会减少，冬季降雨量就会增多。综上所述，水利水电工程的建造对降雨量、降雨分布、降雨时间分布等方面都产生了影响。无形中的变化却造成有形的破坏。
1.3 水利水电工程对水体的影响
当水库建成以后，大量的水容纳于一个地方，库内的水无法及时流出，造成“死水”的堆积，水库储存较久的水会让被淹没的植物腐烂更快，大量腐烂的植物会消耗水中的氧气，水中形成大量的二氧化碳和沼气甚至毒物质和难降解的重金属，形成次生污染源。
1.4 水利水电工程对物种的影响
在大坝开闸时，水流速度过快，产生了大量的氮氧，幼鱼会因此死亡。鱼的大量死亡会对土壤造成恶劣影响，土壤的污染又会破坏植物。水库蓄水会造成水库周围土地大量被浸没，长久以来，周围的土地不再适合植物生长，不充足的氧气、土壤浓度的改变将会造成难以逆转的生态危机。库区周围的土壤过于湿润，导致养分不足，植物无法扎根立足于此，造成大量的植物失去了赖以生存的家园。
1.5 水利水电工程对人们生活的影响
水利水电工程在施工过程中难免会产生并没有处理完全的废水，废水直接通过排放管道进入河道，造成河水的污染。水污染的严重化给人们的日常生活带来了不方便，比如，施工过程中会产生一些难闻的气味，含化学物质的气体进入人体内，潜移默化地伤害着呼吸系统;河道水污染造成周围的居民饮用水质得不到保障，长期住在附近的居民无法享受良好的水源，对生活质量有所影响;施工期间，难免会产生噪声，影响了周围居民的生活。综上所诉，水利水电工程的建立对人们造成了许多影响，空气质量的下降也使得生病率大大提升。
1.6 社会及人文资产破坏
为了经济的发展，各地政府都争先恐后地要求在本地建立水利水电工程。然而，水利工程建设对社会与人文资产的\'影响巨大。如果一个地方确定要建设水利工程，则当地就要为此准备，人们世世代代居住的地方选为建筑地后，当地百姓不得不背井离乡，曾经无数的记忆却成为现代化器械工作的场所。同时，如果水库恰好选中有大量文物古迹的地方，则为了大力开发水利水电，人文资产必定受到损坏，得不到保护的文化只能在经济发展中消失殆尽，唯一残存的可能只能来源于老一辈的记忆。因此，在进行水利水电工程设计和选址时需要慎重决策，尽量不迁移群众和破坏人文资产。
关于火车发展历程的英语作文【二】
现在疫情当前，为了学生安全，不集聚在一起，我们不能到学校上课，历史上放得最长的一次寒假。为了我们学习，老师在网上直播辅导我们学习。
At present, for the sake of the safety of students, we cant go to school without gathering together. Its the longest winter vacation in history. For our study, the teacher tutored us live online.
为了这次疫情，全国各省各地展开“停课不停学”老师直播上课行动，许多教育机构推出各种学习软件。名师在线免费教学，帮助学生学习，在线辅导。
In order to deal with the epidemic, all provinces and regions across the country launched a live action of \"no suspension of classes\" for teachers, and many educational institutions launched various learning software. Famous teachers online free teaching, help students learn, online tutoring.
因为上网课直播，各省老师出现了不同的争论。湖南哪吒“对多数学生说，网课的授课效果根本得不到保证，这种形式主义何必存在？”我觉得湖南老师说得不错，上网课，有一部分爱学习的学生能坚持上网课，但是有一部分不自律的同学开着直播就该干嘛干嘛去。所以说上网课不一定得到学习效果。
Because of the live broadcast of online classes, teachers in various provinces have different arguments. Hunan Nezha said to most students that the teaching effect of online courses is not guaranteed at all. Why does this formalism exist I think Hunan teachers are right. In the online class, some students who love learning can insist on the online class, but some students who are not self disciplined can do what they should do when they open the live broadcast. So online classes dont necessarily get learning results.
我个人是觉得上网课没什么学习效果，上网课，老师在线直播辅导各同学，但是人数多，老师又不能每一个人都顾及得到，每个人的问题不一样，只能挑重点讲。一个人在房间里学习，没有在学校教室里学习氛围好。作息时间混乱，晚上熬夜，晚睡觉，预定多个闹钟。早上起来打完卡接着睡。上网课老师不能面对面教导，许多同学都是敷衍了事。老师与同学之间缺乏互动，对于学习好求者可能受益匪浅，但是对于厌倦学习者，学习上没有一点效果，需要老师面对面教导，当面监督学习情况。
Personally, I dont think the online class has any learning effect. The online class and the teachers live online tutoring for each student have a large number of students, but the teacher cant take everyone into consideration. Everyones problems are different, so we can only focus on them. A person in the room to study, not in the school classroom learning atmosphere. The schedule is chaotic. Stay up late, go to bed late, and reserve multiple alarm clocks. Get up in the morning, punch in and go to sleep. Teachers cant teach online lessons face to face, many students are perfunctory. The lack of interaction between teachers and students may benefit those who are good at learning, but for those who are tired of learning, there is no effect in learning. Teachers need to teach face-to-face and supervise learning face to face.
上网课对贫困家庭来说，不方便，有可能老是断网，要是家庭人口多的家庭，孩子都在上网课有可能网络卡。住在农村里的有一些没有信号不好的同学来说也麻烦，不能好好上网课。对上小学的同学们都是没有手机的，父母要出去工作，根本起不到学习作用。
Internet class is inconvenient for poor families. It is possible to always disconnect from the Internet. If there is a family with a large population, it is possible for children to use Internet cards in Internet class. Living in the countryside, some students who dont have a good signal are also in trouble. They cant have a good online class. There is no cell phone for the students in primary school. If parents want to go out to work, they cant learn at all.
学生的专注不在直播上，面对着QQ、微信、游戏、电视的诱惑，有很多学生难以拒绝诱惑，没有吧精力放在上网课上。老师也不知道学生在干什么，人数过多，有的学生一边手机上网课，一边睡觉。或者手机上网课，而学生却在看电视。手机电脑电视对眼睛视力有一定影响，对眼睛不好。
Students focus is not on live broadcast. Facing the temptation of QQ, wechat, games and TV, many students are hard to resist the temptation and have no energy to focus on online classes. Teachers also dont know what students are doing. There are too many students, some of whom are sleeping while taking lessons on the Internet. Or mobile Internet class, while students are watching TV. The mobile phone computer TV has certain influence on the eyesight, but it is not good for the eyes.
所以我觉得，上网课不一定取得到老师授课学习效果，有一些学生未能适应网上学习。学习情况未能得到提升。但是在这个特殊时期，我们现在只能在网上学习了，无论如何，还是希望各位同学们认真上网课，能学一点是一点了。希望学校开学通知早一点来，开始怀念在教室里面学习的日子了。
So I dont think that online classes can achieve the effect of teaching and learning by teachers, and some students cant adapt to online learning. Learning has not been improved. But in this special period, we can only learn online now. In any case, I hope that all the students will take online classes seriously and learn a little bit. I hope that the school notice will come earlier and start to miss the days of studying in the classroom.

关于火车发展历程的英语作文【六】
童年是一幅画，孩提时代的纯真爱动把我的童年映照的绚丽多彩。绚丽多彩的儿时当然免不了很多有趣的事，在其中有一件，我迄今还清晰地还记得。
我儿时非常喜爱看神话片，尤其是《聊斋》。
有一次，父母因临时性急事，需晚点回家，姥姥也没有，我想：这下可惨了，我多么的想让父母留下陪着我呀。可唉！只能认命了。
夜里，四处静悄悄的，仿佛全球只剩余我一个人了一样。我内心简直十五个吊桶打水七上八下。总算挨来到入睡的時间，正要熄灯，忽然听到了得哒、得哒的声音。这可将我吓傻了，我一下子坐了起來，准备出来看一下。可正当性我走到门口的情况下，那怪声音又响了起來，并且比刚刚的声音还大。我被他吓得从此害怕开关门了，一下子钻到被窝里。我用被子牢牢地地遮住，脑中又回想到《聊斋》中这些三头六臂、吐着长舌头的妖怪。一想起这种，我害怕的心理状态又加剧了，果断一把把被子蒙住头，口中还不断的嘀咕：千万不要吃我，千万不要吃我。
过去了一会，沒有动静，又过去了一会，也還是沒有一切动静，这下可将我惹急了，想着：是福不是祸，是祸躲不过。谁怕谁呀。我一口气取下了蒙上头的褥子，拿了一根大棒，壮着勇气把手打开，接着就是一阵狂打。可我睁开眼睛一看，一片空白。但那类怪声音是哪里来的呢？我循声放眼望去，原来是自来水龙头没相关好，滴在蓄水池里传出的声音，原先仅仅虚惊一场啊，我大舒了一口气。
这全世界本沒有鬼，而这些说白了的鬼却来源于你心里。
关于火车发展历程的英语作文【七】
童年，是五颜六色的。今晚，我们走进小菜叔叔的童年，听他的趣事。
小菜叔叔露出洁白的牙齿，笑眯眯地说起一岁时的故事。他讲的时而快时而慢，还一边做着风趣幽默的动作，有时把手举得老高，有时掐住自己的脸，有时走来走去像回忆什么，搞得大家哭笑不得。
在他讲述完趣事，还让我猜故事名。有的.同学不假思索地举起手，小菜叔叔却在黑板上写了3个字—30法则（思考30秒后再举手），大家只好把手放下来，个个绞尽脑汁认真思考起来。30秒一到，同学们争先恐后地举起手来抢答，“瀑布”、“反击”、“改诗”……，答案许许多多，可小菜叔叔都说是错的，回去再好好想想。
因为时间的关系，所以从一岁，直接连跳到七岁了。这次他想听听同学们七岁的趣事，大概是有些同学胆怯，或者一时想不起什么趣事，所以举手的人很少。见此情景，他说：“想要学习好，就要当小老师。”这话一出，空中立刻出现了密密麻麻的小手。同学们各自讲说了童年发生的趣事，终于轮到小菜叔叔讲了，好奇的我一直在想：什么事情是他七岁时最深刻的呢？是不是和我一样？结果他记忆犹新的是面试，他讲的绘声绘色加上夸张的动作，让所有的同学听得都入了迷。
调皮的时间总是喜欢出来捣蛋，一转眼，就结束了，好想和大家一一分享太多的童年，因为它总是将不完！
关于火车发展历程的英语作文【八】
Elephants are the biggest wild animals in land, in the world. But now, they are also in danger. Let me tell something to you about them.
Elephants are big and strong and they are grey. They have long trunks and tusks, so they look a little dangerous. But in fact, they’re friendly towards each other and hardly hunt people.
Elephants have ears like fans, they make them look bigger and bigger.
They live in a group together for many years, they’re a big family. They also have good hearing and good sense of smell. Elephants can do lots of things if people train them. For example, they can carry heavy things, can do as a vehicle, ext.
Badly, it’s difficult for elephants to survive in the world usually because of people. If people sell tusks, they will make lots of money.
So, many people kill elephants for their tusks. Living areas are also an important reason of the die out of elephants.
Animals are our friends, we should protect them, or the number of wild animals will getting smaller and smaller.
