“医生来了,医生来了!”“调皮鬼”李骏边喊着边飞一般地冲进教室。刚才有闹有笑的同学顿时像一群受惊的小鹿,纷纷跑回了自己的`座位。今天是学校打乙肝预防针的日子,这不,现在轮到了我们班。
果然,三位白衣天使幽灵般地飘进了教室,四周的空气刹那间仿佛凝固了。教室里到处人心惶惶,同学们有的惊吓得身子一个劲发抖,有的害怕得蜷缩在了墙角里,还有的竟喃喃自语地拜佛祈祷:“阿弥陀佛,千万别让我是第一个。”一种前所未有的恐惧感与紧张感笼罩着教室,似乎是世界末日来临了一样。
“谁先来打针!”当医生的话音响起,整个教室鸦雀无声,静得连一根针掉落在地上都能听得一清二楚,没人敢回应医生的话。医生看见同学们畏畏缩缩的样子,便再次重复了刚才说的话,但同学们依旧噤若寒蝉,悄无声息。“哪位同学是班长?能带个头吗?”医生抑制住心中的不耐烦,发话了。只见全班同学那明亮的眼睛齐刷刷都扫向了我,那目光中带有一丝丝的同情。我万般无奈,只好慢吞吞地走上讲台,像个木头人似地站在那里,怯生生地伸出了右手。医生将浸过酒精的棉签涂在了我的胳膊上,让我不禁感到一丝寒意蹿上心头。我屏住呼吸,把头扭向了一边,浑身不由得起了一层鸡皮疙瘩。当医生的针头快要触及我的皮肤时,时间似乎在瞬间停止了,同学们有的紧眯双眼,不敢看针头与皮肤“亲密接触”的那一刻;有的则把头伸得像长颈鹿一样,观看着我面对“死刑”的慷慨表情。突然,我感到胳膊上有一种被蚊子叮咬的刺痛,我睁开双眼一看,预防针竟然已经顺利打完了。
我潇洒地走下奖台,同学们立刻凑过来,七嘴八舌地向我进行了“现场采访”:“打预防针疼吗?”“会不会流血呀?”……。我装出一副大无畏的样子说到:“没事的,就像被蚊子叮咬一样,一点也不疼。”有了我的带动,同学们也都不害怕了,都争先恐后地排队打针,医生也忙得七上八下,结果没过一节课,我们全班注射预防针的任务就大功告成。
经过这次打针事件,我发现,表面让人感到很害怕的事情往往不一定是件坏事。
Yesterday, our class had a discussion about whether junior students could ride electric bicycles to go to school. 25 students of our class agreed with it, because they said that it is convenient for them and it could take less time to go to school. If they took bus, sometimes the bus come late and it might make them late for school. But the other 35 students didn't agree with them. They said it is not safe for the junior students to get to school by electric bicycles, for they are too young. They also said in the morning the traffic was very busy and the students couldn't ride electric bicycles quickly. Besides, there are too much electric bicycles in the street now, they can get hurt easily.
昨天,我们班讨论了关于中学生是否该骑电单车上学的问题。班上25位同学表示赞同,因为他们认为这样比较方便而且更省时。如果他们坐公车,有时候公车来得晚就有可能使他们迟到。但是,另外的'35位同学不同意他们的看法。他们认为中学生骑电单车上学是不安全的,因为他们还太小了。他们还认为早上交通繁忙,学生骑车不能太快。而且,现在路上的电单车太多了,他们很容易受伤。
坐在电脑前,无意间看到一段短文诉说天花做乱时百姓生活的艰辛,我情不自禁往窗外车水马龙的景象望去,生活在二十一世纪的我们,实在难以想象当时恐怖的情况。
十八世纪末时,天花是世界上最恐怖的传染病,在英国每年有四万多人死于天花;在俄国平均每七个小孩,有一个小孩会因天花而死,面对这致命的传染病,全球各地却是束手无策,惶恐以待。爱德华?金纳出生于英国告罗士打郡伯克利牧区,是一名在乡村行医的英国医生。当时流传一个人只要曾经染上牛痘,便不会染上天花。金纳由此意会到牛痘与天花有关,并进一步进行实验。他在一名男孩手臂上划了几道伤口,然后接种牛痘。男孩在染上牛痘的6星期后康复,金纳再替他接种天花,结果男孩完全没有被感染,证明牛痘能使人对天花免疫。
金纳将此称之为“预防接种”,得到“免疫学之父”的名头,并替后人打开研究的通道,使巴斯德、科赫等人对其它疾病展开研发治疗及免疫的方法,此后,巴斯德等人发明各种疫苗,我们才有安定的今天。在发明疫苗前,人心惶惶,大家怕惨死于病魔之下。发明疫苗后,人们不再成天担心,虽然目前只有天花成功的在世界上绝迹,但我们更了解这些可怕的病菌了,也懂得如何去预防它。“天下没有不可能的事”,从前,意大利人视天花为外星球来的瘟疫,在爱得华?金纳医生发明疫苗后,使像“天花”这种令人生畏的传染病也能从此消失。
如今我们享受医学研究成果带来的便利、舒适,感冒了,吃个药,很快就好了,甚至打个预防针,就不怕流行性感冒的'肆虐,若不是有这些前人伟大的发明,我们焉有今日的太平盛世?公元1871年的普法之战,约三万五千人死于天花,比死在枪炮下的人还多,可见天花在当时的恐怖!然而,藉由爱德华?金纳发明的疫苗,人能却能逐步走出天花的阴霾。
一阵笑声传来,将我的思绪拉回现实。窗外是一个安宁的世界,而我的内心深处,由衷的感谢金纳医生。若不是他的发明,地球上的人类,无法如此安逸的生活。
these young people are wrong. in my opinion every student should have a knowledge of housework. after all, they will have a family of their own, and they should do their part in keeping a good home. boys should also learn to do housework, for what will they do if they remain single? though not all boys remain single, yet they will be very helpful in the family if they know some housework. anyhow they will not lose anything, but, on the contrary, they will gain something useful.
for what i said above, we can find some eamples of our fellow-students studying abroad. all young men do housework as girls do. someone would argue that we can employ servants. this is true. however, what shall we do if the servant leaves us and all things are left to ourselves? we just cannot leave our clothes as they are and let worms and ants eat them up. and what can we do it we go and study in a foreign country where servants are out our means to employ? we must work for ourselves. why not start to learn to do housework now or else it will be too late? everyone should learn to do housework. what do you think about my idea, boys and girls?
i think students should share some housework with their parents. the reasons are as follows. first, doing some housework can enable the students to have some sense of responsibility. there is a lot of housework in each family. as a member of the family, each one should do his or her share. since a student is a member of the family, undoubtedly, he is of no eception. in the second place, doing some housework can give the student opportunities to get to know his parents better. by doing housework, a student will know how hard it is for his parents to go to work everyday while raising a
family. he will make even greater efforts in his study later on. finally, doing some housework can give the student a chance to do some physicaleercises. since the student has to sit studying most of the time, this is certainly beneficial to his health.in light of the above, i strongly recommend that those who are not in the habit of doing housework start doing some right now. your parents will be pleased and you will learn something from it.
