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.
Elephants are the biggest animals on the land.They are big and srong.They have big ears and trunks.They can walk quietly and help people move heavy things. They are very friendly,kind and always live together.But the number of elephants reduces.People kill elephants for their ivories.We must take action to protect them or else they will extinct from the world.
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。
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。
随着时光的流逝,我那既天真又有趣的童年也悄悄地走开了。然而充满童趣的一幕幕已在我记忆的脑海里定格着。
记得那是我6岁的时候,我看见妈妈买回来一大袋的香瓜子。当妈妈放下袋子的时候,我便像离弦的箭一样跑到袋子的前面,把袋子撕地七零八落,取出了一包香瓜子。当我吃着香喷喷的瓜子时,不禁问妈妈:“妈妈,这些这么香的瓜子从哪儿得到的呢?”妈妈耐心地对我说:“这些瓜子是由向日葵那里得来的,只要种下一颗花籽,就能种出许多美味的香瓜子。”我听着听着就流下了口水,脑海中并想出了一个计划。
我把一包香瓜子全种在地里,浇了许多桶水。可是一个星期过去了,也还没看见香瓜子长出来。我急得像热锅上的蚂蚁。于是,我就把香瓜子全挖了出来。挖出来一看,香瓜子不但没有长出鲜嫩的小花苗,反而上面还有许多小蚯蚓。我就把这件奇怪的事告诉了全家人,家人们笑得前仰后翻,我不知道怎么回事,就带着疑惑的心情问妈妈:“妈妈,大家为什么要笑啊?”妈妈笑着说:“儿子,你拿煮熟的香瓜子去种,当然种不出向日葵,只有生的香瓜子才能种出向日葵,不信你就试一试。”在妈妈的帮助下,我种的向日葵终于长出了小花苗。
这件事,虽然已经过去了很久,但是这件童年趣事像天边的一颗璀璨的星星,永远留在我心中的星空上。
今年的寒假是个不平凡的寒假。由于新型冠状病毒,开学时间延迟。为了保证教学工作的正常进行,学校开展了网络课程。今天是网上教学的第四天,同学们都慢慢适应了这种新颖的教学方法,也没有因为老师的监督而松懈了自己的学习,在课上积极回答老师的问题,认真听讲,课后也按时完成自己的作业。而成为“主播”的老师们轮流完成各门学科的'授课,上课很积极,课件准备的很用心,知识点也总结的很到位。我感觉这次网上教学的方法,即能保护同学和老师的安全,又能进一步激发同学们学习的兴趣,从而提高学习的效率。
This years winter vacation is an extraordinary one. Due to the novel coronavirus, the school hours are delayed. In order to ensure the normal progress of teaching, the school launched the network course. Today is the fourth day of online teaching. The students have gradually adapted to this new teaching method, and have not slackened their study due to the supervision of the teacher. They actively answer the teachers questions in class, listen carefully, and finish their homework on time after class. The teachers who become the "anchor" take turns to complete the teaching of various subjects. They are very active in class, attentive in courseware preparation and in place in knowledge summary. I feel that this online teaching method can not only protect the safety of students and teachers, but also further stimulate students interest in learning, so as to improve the efficiency of learning.
2020年春节,一场新型冠状病毒引发的肺炎疫情笼罩了中华大地。人们开始足不出户,生活变得压抑起来。在这样的背景下,教育部发布通知“停课不停学”,正式开辟了一种崭新的学习方式,网上授课。
A novel coronavirus epidemic caused by pneumonia in 2020 was enveloped in China. People began to stay indoors and life became oppressive. In this context, the Ministry of Education issued a notice of "no suspension of classes", officially opening up a new way of learning, online teaching.
每天在钉钉直播群里上课,我认为这种教学方式变得生动活泼,我的学习兴趣也提升了许多。老师们每节课在直播间里以课件的形式向我们授课,整节课的知识框架变得清晰明朗了起来,这是十分有利于我们接受并消化东西的。
Every day in nail live group classes, I think this teaching method has become lively, my interest in learning has also increased a lot. Teachers teach each lesson to us in the form of courseware in the live room. The knowledge framework of the whole lesson becomes clear and clear, which is very conducive to our acceptance and digestion.
其次,就是这种方式突破了原有的教学模式。在学校是每一个学科只有一个老师授课,但在网上授课则是许多不同的老师担任我们的任课老师,使我们能充分了解到不同老师的教学风格和特点,进而可以得知自己感兴趣的教学方式。
Secondly, this way has broken through the original teaching mode. In school, there is only one teacher for each subject, but in online teaching, many different teachers are our teachers, so that we can fully understand the teaching styles and characteristics of different teachers, and then we can know the teaching methods we are interested in.
再者,在网上授课时,每个老师一天只需上一节课或两节课,这就为老师们挤出了充足的时间为同学们批改作业及写评语,可以使同学们了解到自己作业的不足和突出的地方,之后就知道我们可以向哪一个方向努力。
Moreover, in online teaching, each teacher only needs to have one or two classes a day, which makes the teachers have enough time to grade and write comments for the students, so that the students can understand the shortcomings and highlights of their own work, and then know which direction we can work in.
总而言之,我们在这足不出户的冬日勃发着学习的兴趣。“冬天来了,春天还会远吗?”我相信,只要我们认真进行网上学习,永远保持着学习的自信,总有一缕阳光,会突破疫情的阴霾,带来温暖的春天。待到春暖花开时,我们再聚校园。
All in all, we are interested in learning in this winter. "If winter comes, will spring be far behind?" I believe that as long as we carefully carry out online learning and always maintain our confidence in learning, there will always be a ray of sunshine, which will break through the haze of the epidemic and bring warm spring. When spring comes, we will get together on campus.
