现在中国流传着一个非常可怕的病,这个病的名字就叫做H7N9禽流感,中国目前确诊109例感染者,其中22人亡。人们因为这件事再也不敢吃鸡蛋、鸡、鸽子……
其实H7N9禽流感病毒并没有我们想象的那么可怕,因为禽流感可防、可控、可治。
禽流感期间,多吃蟹味菇、白玉菇等食用菌类!因为菇类除了具有蔬菜拥有的维生素,矿物质和纤维素外,还含有2。7%的植物蛋白质和20多种氨基酸,是最接近肉类的蔬菜品种。更重要的是蟹味菇、白玉菇等高端食用菌具有抗病毒提高免疫力的功效!
发现疫情时,应尽量避免与禽类接触,对鸡肉等食物应彻底煮熟;保持室内空气流通,尽量少去空气不流通场所;注意个人卫生,打喷嚏或咳嗽时掩住口鼻。H7N9是家禽、飞禽中传播的一种病毒性传染病,截止今天,我国发现的60个病例都是直接来自于禽类的传播,还没有发现人与人之间的传播。鉴于此,预防此病的主要手段就是截断病禽与人的接触。北京发现的一例是家禽饲养户,上海发现的病例均有病禽接触史。
所以只要我们按照上面的建议去做,就会离H7N9远远的,所以禽流感并不可怕,因为它可防、可控、可治。

小时候,我最害怕的就是爸爸妈妈都去上夜班的晚上。家里只剩我一个,这时候,什么小偷啊、鬼啊、老鼠啊……马上涌上我心头。
记得有一次,爸妈又上夜班去了。我洗完澡后就写作业,不一会儿就写完了。于是,我打开电视想轻松一下。这时候,电视一片白花花的。唉,真是祸不单行啊!电视没得看,我的脑子就开始胡思乱想,怕小偷进屋偷东西,又怕老鼠来咬我,又怕鬼来把我吃掉,又怕……这时候的我拼命地叫自己别乱想,可脑子就不听话。突然,我的脑子里闪过一个念头:小偷不是怕警察叔叔吗?于是,我拿出纸,画了一位威武的警察叔叔,贴在门上。接着,我又画了一只大黑猫,看那些讨厌的老鼠敢不敢出来咬本小姐!吃了这些“定心丸”,我的`心不再胡思乱想,随手拿起一本作文书看了起来。时间过得真快,一晃就到了九点半,妈妈回来了。妈妈问我是怎么回事,我便一五一十地告诉了妈妈,妈妈还夸我聪明呢!
从那以后,我发现了一个人在家并不可怕,有时还挺好玩呢!只是看你会不会一个人去寻找乐趣。
1。 头绪分明,脉络清楚
写好记叙文,首先要头绪分明,脉络清楚,明确文章要求写什么。要对所写的事件或人物进行分析,弄清事件发生、发展一直到结束的整个过程,然后再收集选取素材。这些素材都应该跟上述五个“ W ”和一个“ H ”有关。尽管不是每篇记叙文里都必须包括这些“ W ”和“ H ”,但动笔之前,围绕五个“ W ”和“ H ”进行构思是必不可少的。
2。 突出中心,详略得当
在文章的框架确定后,对支持故事的素材的选取是很关键的。选材要注意取舍,应该从表现文章主题的需要出发,分清主次,定好详略。要突出重点,详写细述那些能表现文章主题的重要情节,略写粗述那么非关键的次要情节。面面俱到反而使情节罗列化,使人不得要领。这一点是写好记叙文要解决的一个基本问题,也需要一定的技巧。如:
One night a man came to our house and told me, "There is a family with eight children。 They have not eaten for days。" I took some food with me and went。
When I finally came to that family, I saw the faces of those little children disfigured (破坏外貌) by hunger。 There was no sorrow or sadness in their faces, just the deep pain of hunger。
I gave the rice to the mother。 She divided the rice in two, and went out, carrying half the rice。 When she came back, I asked her, "Where did you go?" she gave me this simple answer, "To my neighbors — they are hungry also!"
3。 用活语言,准确生动
记叙文要用具体的事件和生动的语言对人、事、物加以叙述。一篇好的记叙文的语言既要准确、生动,又要表现力强,这样才能把人、事描写得具体生动,其可读性才强。试比较下面一篇例文修改的前后效果。
原文:
One day Xiaoqiang was wandering away。 He was soon lost among people and traffic。 He could not find the way back home and started crying。 Just then, two young students who were passing by found him standing alone in front of a shop and crying。 They went up to Xiaoqiang and asked him what had happened。 Xiaoqiang told them how he got lost and where he lived。 The two students decided to take him home。 Mother was pleased to see Xiaoqiang come back safe and sound。 She invited the two students into the house and gave them some money, but they didn't take it。 She served them with tea but they left。
修改后:
The other day, five-year-old Xiaoqiang left home alone and wandered happily in the street。 After some time, he felt hungry so he wanted to go back home。 But he found he was lost among the crowded people and heavy traffic。 When he could not find the way home, he started and crying。 Just then, two young students who were passing by from school found him sanding crying in front of a shop。 They immediately went up to him。
"Little boy, why are you standing here crying?" they asked。
"I want Mom, I go home。" said the boy, still crying。
"Don't worry, we'll send you home。"
And they spent the next two hours looking for the boy's house。 With the help of a policeman, they finally found it。
When the worried mother saw her son come back safe and sound, she was so thankful and she invited the students into her house。 Gratefully, she offered them some money, saying it was a way to express her thanks, but the young students firmly refused it and left without even a cup of tea。

今天,我们这里下了一天的鹅毛大雪,它足足下了一天。
一下课,同学们便蜂拥而出,到操场上去。在那里,有的在滚雪球,有的在堆雪人,有的在打雪仗,还有的在跑来跑去追着雪花……我来到操场,滚了一个大雪球,然后,把它拿回到教室里面。来到教室里面,我把它分成了许多小雪球,向同学弹了过去。弹了一会儿,我觉得不太好玩了。我就拿起雪球在黑板上面写字。可是,写出来的字,不管我怎么擦都没有擦掉。结果,我在上课的时候被老师批评了一顿。
第二节下课后,我来到阳台上看别人玩雪。我看到操场上一、二年级的学生把雪球滚得有圆筒那么大。然后,他们又滚了一个小一点的雪球。接着,他们把小雪球放在大雪球上面。哦,原来他们是在做雪人。他们在大雪球的两侧分别插上一根树枝当双手。他们又用石子当眼睛……他们做好后,就围着雪人蹦来跳去,好象在和雪人一起做游戏。
这时,我向教室里面看去,看到有的学生躲在教室里面,身上穿着棉衣棉裤,脚上穿着棉鞋,还在那里冻得发抖。他们一边哆嗦着一边在骂着老天不应该下雪。那些在雪地里玩雪玩得过分的学生,身上的衣服裤子都湿了,只得不停地跺脚来取暖。有的学生玩得身上在直冒热气。于是,我对教室里面的学生说:“你们赶快出来玩雪,否则你们会冷的。”他们听了我的话,纷纷走出教室和我一起玩起了雪来。过了一会儿工夫,他们都对我说:“你说得对,坐在教室里面只有冷,到外面来玩倒很热。谢谢你的提醒!”我说:“不用谢!”
我和他们一起玩着雪,心里在想我们不能够害怕,自己勇敢就会战胜害怕和寒冷。
