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,就像一个五彩斑斓的盒子,装满了我小时候天真烂漫的故事,装满了我幼稚可爱的快乐。虽然我儿时发生过的每一件事,不是什么新鲜的事儿,但是我依然记忆犹新。现在,我把这盒子里最晶莹剔透的珍珠拿给你们看。
我小的时候,最喜欢吃糖果,如棒棒糖、饼干和巧克力等,但是妈妈却不让我多吃,因为怕我蛀牙和口腔溃疡,所以我很少吃到糖。有一次,当我吃着幼儿园老师给的糖果时,我突然想出了一个好主意:把每次吃剩的一些饼干和巧克力装到一个小盒子里,日积月累,到明年一定有满满一盒子的糖果吃了。说干就干,一个星期后我积累了两块饼干和一颗糖,我看了心里很高兴。不知过了多长时间,我积累了满满一盒子糖果。
有一天夜里,我感到肚子咕咕地叫,我很想吃糖,于是,我悄悄地把我珍藏的“宝贝”拿出来,小心翼翼地打开盒盖,往里边瞧了瞧,我看到饼干上有一点一点的黑点,心想:“咦,饼干脏了,我给它洗个澡吧!”我在饼干上面加了几滴水,再关上盒盖,然后拿起盒子上下轻轻摇一摇,再左右轻轻晃一晃,我要把饼干洗得干干净净。我又打开盒盖,突然,一股又酸又臭的味道扑鼻而来,真难闻!为什么会这样呢?我正纳闷,不知什么时候,妈妈发现我神神秘秘的,就奇怪地问我:“孩子,你怎么还不去睡觉?”我把事情的来龙去脉一五一十地告诉妈妈,妈妈听了哈哈大笑,告诉我:“傻孩子,‘黑点’说明饼干发霉了。食物都有保质期,如果过了规定的时间就不能再吃了。你以后可不要做这种傻事了。”我听了妈妈的话,恍然大悟。
看了我的童年趣事,你是不是觉得很有趣呢?如今我一想起童年做过的那些“傻事”,就会情不自禁地笑个不停。快乐的童年,令我难忘。
我的童年是多姿多彩的,有喜,有怒,有哀有乐,那些事情有时很可笑,有时又很无奈。
我的小时候,什么都不知道,主要是哭,学会走路的时候乱跑,到早教班也是玩儿,好不容易学会了一个“大"字,还是我哥教会我的。我小时候还经常逃课,逃午睡,躲到男厕所里不出来,由于大部分老师都是女性,所以我们总能逃过午睡。现在想想,我都不知道那些时间我是怎么耗过去的。
有次,妈妈因为当时的我还够不着马桶,就给我买了个尿盆回来,绿色的还泛着点黄色,刚拿回来的时候我还不知道这是干什么用的,好奇的这边瞧瞧那边看看,端详了一阵后,举起了尿盆,妈妈不知道我又在搞什么怪也只是看着我不为所动。只见我”咣“的一下把尿盆我的头上,当帽子戴了!我那时候头还很小,如果按我现在的头围把尿盆往头上扣,应该像个西瓜太郎,但像我原来那么小的头,尿盆往上一放把脸也给盖住了,成了四不像,妈妈看见了”扑哧“笑出了声,看不下去了,过来纠正了我,我乖乖的往里面撒尿,尿完之后把尿到了又扣在了头上,一点儿也不长记性。
我童年的事,常常有一些滑稽的举动,但是在家长看来它是可爱的,在现在的我看来是可笑的,我一些早教班的老师对我的逃课现象当然是可气的。
小时候的我就是这样:可爱,可笑又可气。
Elephant is the largest animal on land today. It weights some ninety kilograms and is about one metre high when born. When it is 12 years old, it studs over three meters and does not grow any more. Elephant is usually grey in color, having a long trunk with large ivory tusks protruding from each side of its mouth. Usually moving in groups and caring for each other, Elephant is know to be a very and gentle creamre. For many years people have used the strength of these poweful animals to move trees and heavy logs. Elephant has been and is a vital tool for people to do many things that would normally be imposs-ible. Elephant is and will continue to be one of the greatest creatures man has ever come into contact with. Its size. beauty, and power willforever be useful to man.
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.
期望寿命在上世纪显著提高。不久,世界上老人的数量将超过儿童。人口老龄化无处不在, 但是低收入和中等收入国家将经历最快和最显著的人口结构变化。这种社会转型代表着挑战和机遇并存。尤其是,各国可能只有一代人的时间为老龄化的世界在卫生和社会体系方面作准备。
在21世纪,广泛的社会发展趋势对健康起着决定性作用,并受到健康的影响。经济正在全球化,越来越多的人在城市工作和生活,家庭模式发生变化,科技迅猛发展。其中一项最大的社会转型是人口老龄化。不久,全世界老年人的数量将会大于儿童,非常高寿的老人数量将达空前水平。
世界不断变化
全世界能够活到80多岁或90多岁的人数将超越以往
例如,80岁或80岁以上老年人的数量将在2017至2050年之间增加到从前的.近四倍,达到3.95亿人。像如今这样大多数中年人和老年人与其父母生活在一起的情况是史无前例的。儿童会见识自己的祖父母,甚至是曾祖父母,尤其是他们的曾祖母。女性寿命平均比男性长六至八岁。
2. 期望寿命在上世纪显著提高
192017年,智利女性的期望寿命为33岁;如今,仅仅一个世纪之后,已经达到82岁。在一个世纪内,寿命显著增加了将近五十岁,而这主要是由于公共卫生的改善。
3. 不久,世界上老人的数量将超过儿童
在未来五年中,在人类历史上,65岁及以上成年人的数量首次将超过5岁以下儿童的数量。到2050年,这些老年人的数量将多于14岁以下儿童。
4. 世界人口正快速老龄化
2017年至2050年之间,全世界60岁以上人口的占比将翻倍,从11%增长至22%。预计在同一时期内,60岁及以上老人的绝对数量将从6.05亿增长到20亿。
5. 低收入和中等收入国家将经历最快和最显著的人口结构变化
例如,法国65岁及以上人口从7%增长到14%花了100多年时间。而巴西和中国等国不到25年就达到了这一水平。
健康老龄化的决定因素
健康老龄化与生命早期阶段相关
例如,宫内营养不良可能会增加在成年阶段罹患循环系统疾病和糖尿病等疾病的风险。儿童期呼吸道感染可能会增加成年阶段罹患慢性支气管炎的风险。肥胖或超重青少年可能会在成年阶段发展成糖尿病、循环系统疾病、癌症、呼吸道和肌肉骨骼疾病等慢性病。
2. 然而,如何老龄化取决于多项因素
人体功能在生命最初一些年增长,在青壮年达到峰值,之后自然降低。降低的速度至少在一定程度上取决于个人生命全程中的行为和面临的健康风险,其中包括吃什么,身体活动如何,以及面临的健康风险,例如吸烟、有害使用酒精导致的风险或暴露于有毒物质的风险。
