“疟疾”——这个词许多人都很陌生。其实疟疾是由疟原虫寄生在人体血液内引起的传染病。通过蚊子叮咬吸血是传播,多见于夏秋季节。
患上疟疾后要及时就医,医生根据临床症状和血检疟原虫进行诊断和治疗。预防疟疾的最有效办法是防止蚊虫叮咬。流行区居民和外出务工人员一定要做好个人防护,野外作业人员要穿长袖衣服或在暴露的皮肤上擦驱蚊剂,从而减少疟疾的传播。另外,住在高疟区或到高疟区工作的人员要定期服用预防药。一旦出现发冷、发热的症状要及时看医生,早期进行抗疟治疗。那么患了疟疾有哪些症状或不舒服呢?主要的症状有发冷、寒战、发热、出汗、头、腰肌及全身疼痛。典型的疟疾多呈周期性发作,表现为间歇性寒热发作。一般在发作时先有明显的寒战,全身发抖,面色苍白,口唇发绀,寒战持续约10分钟至2小时,接着体温迅速上升,常达40℃或更高,面色潮红,皮肤干热,烦躁不安,高热持续约2~6小时后,全身大汗淋漓,大汗后体温降至正常或正常以下。经过一段间歇期后,又开始重复上述间歇性定时寒战、高热发作。
疟疾是一很古老的疾病,远在公元2000年前《黄帝内经·素问》中即有《疟论篇》和《刺论篇》等专篇论述疟疾的病因、症状和疗法,并从发作规律上分为“日作”、“间日作”与“三日作”。然而,直到1880年法国人Laveran在疟疾病人血清中发现疟原虫;1897年英国人Ross发现蚊虫与传播疟疾的关系,它的真正病因才弄清楚。而疟疾也可引起贫血和脾肿大。
疟疾广泛流行于世界各地,据世界卫生组织统计,目前仍有92个国家和地区处于高度和中度流行,每年发病人数为1。5亿,死于疟疾者愈200万人。我国解放前疟疾连年流行,尤其南方,由于流行猖獗,病死率很高。解放后,全国建立了疟疾防治机构,广泛开展了疟疾的防治和科研工作,疟疾的发病率已显着下降。疟疾怎样防止蚊虫叮咬就能大致的预防了,疟疾也并不可怕,只要注意就可以了!
不明其意,歧视是戴着有色眼镜来看人,谁若是不符合自己的标准,就是被淘汰的对象。歧视,不仅在人类社会常见,在动物界也是常见,它无处不在,但很多人对它的认识却仅限于表面层次,而无法正确的对待歧视。
不管出现怎样的.歧视,它的影响都是双项性,除了对被歧视者有直接的损害,对歧视者也有不可避免的间接危害,只是,我们总是看到了前者,从而不断的批判后者,是他们铸造了不公平。其实,他们给被歧视者不公平待遇,自己也受到了不公平待遇带来的损失。
比如说一家公司存在性别歧视,只招收女工,那它就会缺少男工的专有服务,很多可以让一个男工解决的事情,就需要耗费几个女工来完成。有时正因为歧视,它需要耗费更多的资金和精力,招聘更好的女工,以此来满足需求。长此以往,性别歧视已经让它付出了双倍的代价,只是自己处在局中仍未察觉罢了。
所以说,想要开始一种歧视之前,最好想想它的两项性,权衡一下,到底哪一项的损害更大,别到最后才醒悟,得不偿失则晚矣。请平等的对待身边的人和事,上帝就会平等的对待你,这个世界就是一个圆,终有一天会遇见。
同学们,我们生活中离不开火。但是假如用火不当,或者治理不好火,就往往很轻易发生火灾。火灾给我们的生命财产安全和国家建设发展造成很大的损失,消防安全十分重要!在我们的日常工作和生活中,应时时刻刻注重消防安全,小心谨慎地用火,只有这样,我们才能建设美好的家园。
记得有一天,我和妈妈正在午睡,忽然闻到一股很浓的烧焦味,妈妈就起床,看看厨房是否忘记关火,没有呀,妈妈又到处查看一遍,仍没有发现什么,于是又继续睡觉。再过几分钟,烧焦味越来越浓,妈妈又起床查看,这时,妈妈往窗外一看,天呀!楼下阿姨家冒出一串串的浓烟。“楼下着火了,传煜,快起床”。火苗迅速地往上窜,我和妈妈马上用湿毛巾捂住鼻子跑到楼下。小区的保安已撬开阿姨家的窗户,用灭火器向着火的地方喷,不一会儿,消防官兵也赶来了,他们用消防水枪灭火,很快火灾就被扑灭了,我们终于松了一口气。原来,阿姨中午在煮汤,出门时忘记把煤气炉关掉,于是造成了这次火灾。
同学们,消防安全系万家。一点点很小的火星,一不小心也许就会造成灾难。所以,作为小学生,我们要熟悉到消防安全的重要性,小心用火,果断不玩火,同时要把握火灾发生后一些基本的逃生知识,减少灾难事故的发生
Do you ever watch movies from other countries? Whenever I do, I think about how similar people really are all around the world. Even though the cultures and languages in those movies are different from mine, people all around the world are alike in their goals and emotions.
One time, I saw a movie made in china that showed parents helping their children with their homework. . My parents helped me the same way. Another time I saw a movie from Argentina. It showed school children playing hide and seek, which is a game I used to play with my friends during recess. Seeing these films demonstrated to me that education is a common goal in every country. Parents want their children to learn so their lives will improve. It also showed me that children in schools everywhere wants to play with their friends. Sometimes the games are similar to ours and sometimes they’re different. Still, they all have the common purpose of fun and learning to work together.
Earning a living is another common goal. I’ve often seen that in movies about other countries. In some countries, people choose their careers from what they like and are good at. In other countries, careers are chosen for them following the traditions of their families. But in every country it seems that people care a great deal about earning a living, and working hard is respected.
Showing people having fun together is always an important part of any movies, no matter what country it comes from. People everywhere want to be entertained, and want to spend time with their families and friends. Different cultures sometimes enjoy different activities, but all cultures enjoy some form of sports, music and dancing.
The movies I’ve seen make it clear to me that no matter the cultural differences between countries, people everywhere have the same basic needs and goals.
