今天的风特别的大,飞沙走石,天昏地暗,天气预报说有沙尘暴。 我去学校的时候衣服很干净,等回来时,衣服都挂有一层土了。街上的行人特别少,风刮的人都睁不开眼睛,举步艰难,顶风骑车的就像蜗牛一样,慢吞吞的。
下面是沙尘暴预防措施 :
1.加强环境的保护,把环境的保护提到法制的高度来
2.恢复植被,加强防止风沙尘暴的生物防护体系。实行依法保护和恢复林草植被,防止土地沙化进一步扩大,尽可能减少沙尘源地。
根据不同地区因地制宜制定防灾、抗灾、救灾规划,积极推广各种减灾技术,并建设一批示范工程,以点带面逐步推广,进一步完善区域综合防御体系。
5.控制人口增长,减轻人为因素对土地的压力,保护好环境。
传说中的“小四眼”,我们班上可有不少。曾经听过医生说,环境污染对眼睛视力有相当恶劣的影响。其实是因为缺乏锻炼、挑食、营养不良才引起近视的原因,而且长时间玩电脑游戏、看电视等一些有辐射的交通工具也是导致近视的主要原因。
经过我最近在班上观察,罗、冯都是假近视,度速不是很深,不要长时间玩电脑,80%的可以不用戴眼镜。因为深圳环境很好、绿化多,我看环境应该不是近视的主要原因,应该是自立能力那一块。主要是学生做作业时照明不足,迫使学生把书本移近,长时间来,近视就会加深。
过量使用电脑,眼睛疲劳。而且千万不要把电脑放在卧室里,因为电脑有辐射,对身体不好,特别是眼睛。当有灰尘的时候,千万别用有细菌的手擦拭眼睛,要不细菌进入眼睛,眼睛会红肿,恶化,特别是别揉眼睛。
我曾经调查过一位近视的同学,他的写字姿势是:曲着腰、头死劲网下低,桌子和眼睛的距离没有一尺,所以导致他近视,但是他的睡眠时间很足、每天早上都出去运动,我相信只要把坐姿改好,眼睛就可以恢复健康。
大家记住几条预防近视的规则:1.不要用有细菌的手擦拭眼睛;2.少接触电脑和电视;3.坐姿,桌子和眼睛的距离要有一尺;4.不要让眼睛过度疲劳,要适当调整好睡眠时间,早睡早起。记住啦!一定要勤洗手。
保护眼睛,人人有责。
近视很正常,可我却感到自卑,因为我虽然近视了,妈妈却迟迟不给我配眼镜,导致我许多远处的东西看不清,而同学们见我没戴眼镜就以为我视力好得很,所以常常嘲笑我——这都看不清?
上课的时候,坐在我后面的那位同学问我黑板上的一道题怎么写,我使劲眨了眨眼睛,可还是看不清题目,又奋力“瞪了瞪”,还是不行,便只好说我不会,同桌惊讶地说:“你这都不会?”既然话已说出口,我还怎么解释呢?唉,没办法,我只好对同桌吐了吐舌头,尽量避开了这个话题。
终于,爸爸带我去医院了,来到眼科医院,挂完了号,就要去测视力,看完了那些横七竖八的“e”,医生皱着眉头给我配配这个镜片,配配那个镜片,整个过程我都像个正在等待成绩公布的差生,很是不舒服。“170度。”医生说,爸爸叹了口气,把我带到了窗户边,指着远处的一个字牌,问我上面写了什么,我眨巴了几下眼睛,吞吞吐吐地说了几个字,像是在考试一样,直到爸爸把眼镜借我,我才能看清到底是什么字。“你啊你……”爸爸指着我,也不知说什么好了,我低着头像是做了什么天大的错事。这时,旁边的一位阿姨凑过来说:“哟哟!怎么小小年纪就这么近视,黑板上的字都看不清了吧?肯定是因为电脑玩太多,电视看太多,手机玩太久,现在这些小学生呐,一个个都迷恋手机……”这位阿姨滔滔不绝的,又说了好多关于导致近视的刺激话,我只好尴尬而又不好意思地点头应和着,唉。
虽然已经近视170度了,但妈妈还是最终决定不给我配眼镜,倒不是心疼钱,说是让我自己恢复看看,说不定是假性近视。这不是更加重我的自卑吗?真是的。
Children's finally here, it is our holiday, but imagine the children also accompanied by together, everybody is more excited.
Children on this day, white clouds float over the blue sky, the children also have made a hot air balloon, they sit together on yourself a hot-air balloon, extremely happy! Balloon flying high, and finally flew to the sky, the children are in the sky holiday, the children sit on clouds, umpa jump, like a frisky little monkey.
Playing children, suddenly to rain cats and dogs, the children of the balloon has stalled, baiyun sister swept away by the wind, the children fell into despair. Is a time of crisis, a group of dragonflies sister and sister flew caught the children, and the safety of the children to the ground.
On the ground, only butterflies woven into a rainbow "lei", the children wear a wreath, some like a fairy, some like a warrior.
Play tired, the children fell asleep between full of fragrance of flowers.
Children's good play my imagination, to one day be able to live in such a children's day.
Nowadays, many famous university campuses have become one of the popular tourist attractions. It has been shown on TV and on the radio that every year thousands and thousands of middle school students visit Tsing Hua University and Peking University and other famous universities in China. In the place far away from the capital city, the local students also visit the universities famous in their own province.
So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists? Different people have different opinions. On one hand, some people argued that it is a good thing for the students to visit the famous university campus in that it can enable the middle students to get more information about the university and they can have enough time and opportunity to prepare themselves with the chance to get into the university. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the public tourism will have negative effect on the universities because it will not only do harm to the environment but also to the intellectual atmosphere.
In my opinion, the tourism to the universities is not a good thing. The campus is mainly a place for study. With the increasing tourism on the campus, it will ruin the spiritual atmosphere in this learning field.
首先,提纯范文 “谋篇布局”及结构模板。
第一段:提出问题或现象。Nowadays, … … have become one of the popular … …. It has been shown on TV and on the radio that … ….
第二段:正反列举人们的看法。So far as the present situation is concerned, is it a good or bad thing to … …? Different people have different opinions. On one hand, some people argued that it is a good thing for … … in that … …. On the other hand, some people hold a negative view about this phenomenon. In their opinion, … … will have negative effect on … … because it will not only do harm to … … but also to … ….
第三段:摆明自己观点。In my opinion, … … is not a good thing. … … With the increasing … …, it will ruin … ….
其次,提纯范文“段落写作”。
段落写作分为统一性,连贯性和完整性三方面。
统一性(unity:段落开头的主题句应该做到不可太宽泛,也不可太具体,做到有较强的概括性才能使下文做到有的放矢的展开。范文第二段首句以设问的方式提出一个问题is it a good or bad thing就有很强的概况性。下文自然会一方面从好的方面说明,另一方面从坏的方面说明。
连贯性(coherence:关联词是使文章段落之间相互连贯的必要条件。范文中nowadays, on one hand, on the other hand, in one’s opinion即以“启承转合”递进的顺序是文章条理清晰,层层展开。
完整性(completeness:以设问句“So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists?”开头,这是平时较少运用的段落写作方式——设问法。“On one hand … …. On the other hand, … ….”是段落写作分类列举法的典型用法。
再次,提纯范文“句子写作”。
1. It has been shown that … …
类似句型:It is known to us that … …
It is said that … …
It is reported that … …
It is controversial that … …
2. “… … Tsing Hua University and Peking University and other famous universities … …。”——并列句。并列句是简单的复杂句。但其运用方法并不简单,注意练习并接句的使用,会使句子显的更加饱满。
3. enable v. 使…能够
I gave him full directions to enable him to find the house.
4. in that = because
表“因为”的连词还有since, for, as,如:
The boy was absent because he was ill. = The boy was absent since he was ill.
此句以我们常用的人称开头,句式简单,我们可以通过把since提前改变句式,如:
Since the boy was ill, he was absent. 句式多样化。
最后,提纯范文“措辞”。
1. attraction n. 具有吸引力的事情。
2. thousands and thousands 成千上万的
形容“多”的表达方法:millions and millions
a multitude of
a great deal of
a large amount of
plenty of
many a
3. “some people argued that … …”中的“argue”并不是“讨论,辩论”的意思,而是“认为”。
I argue that … …
I maintain that … …
I claim that … …
I insist that … … = I think that … …
I hold that … …
I assert that … …
I assume that … …
4. negative adj. 否定的.,相反的
hold negative view = hold opposite opinions
5. phenomenon n. 现象
social phenomenon 社会现象
natural phenomenon 自然现象
6. intellectual adj. 聪明的= intelligent, bright, clever
(选词策略:使用最近所学的单词,如intellectual > intelligent > bright > clever
在分析并掌握范文之后,我们需要运用范文知识练习仿写。笔者运用2005年12月范文中的模板结构仿写了2006年12月的四级作文,以供参考:
1. 许多人喜欢在除夕夜看春节晚会
2. 但有些人提出取消春节晚会
3. 我的看法
Nowadays, the Spring Festival Evening has become one of the popular topic and attractions during every traditional New Year’s Eve. It has been shown on TV and on the radio that every year thousands and thousands of Chinese people appear to be accustomed to enjoying the sights and sounds of a brilliant feast, while gathering with their beloved family.
However, an increasing number of people have voiced different opinions towards it. So far as the present situation is concerned, is it a good or bad thing to cancel the Spring Festival Evening? Different people have different opinions. On one hand, some people argued that it is a good thing to amuse the audience in that it is composed by a numerous adequate programs, such as the emotional song, the graceful dance, the funny short sketch, the amusing comic dialogue, the delightful magic, and the marvelous acrobatics and so on. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the Spring Festival Evening will have negative effect on the family harmony because it will not only do harm to having the talks between family members on the Spring Festival Eve but also to enjoying the gourmet meal in a fancy restaurant.
In my opinion, the Spring Festival Evening is a good thing. It may not remain a must for all people, but it can bring us a strong sense of festivity and serve as an alternative among the variety of holiday activities. With the increasing audience of the Spring Festival Evening, it will ruin a distinctive culture during the Spring Festival vacation.
黄沙满天,大雾蒙蒙,一股黄风卷起……你们也许以为你在看电影,也许以为这在做梦,总而言之,你们相信这是真的吗?其实,这是沙尘暴“捣的\'鬼”。沙尘暴是沙暴大哥和尘暴小弟的总称,他们经常用风把地面大量沙尘卷入空中使空气十分浑浊。他们的出生原因是因人们大度砍伐树木与植物而产生的。沙尘暴兄弟俩作为一种高强度风沙灾害,并不是有风的地方他们都喜欢,只有植物稀疏的地方,他俩才去那里。如果那里是植物和树极缺的地区,他们就会亮出自己的绝招——瞬时风速每秒达25米,风力10级以上,可能使地面水平能见度低于50米!
沙尘暴是一种危害性极大的灾害性天气。当沙暴大哥和尘暴小弟找到自己的“作案地点”时,会以排山倒海之势滚滚向前移动。他们的“作案”后造成的后果可不小,有时,会使大片农田受到沙埋或被刮走活跃土,或者农作物受霜冻之害。它还能加剧土地沙漠化,给人民生命财产造成严重的损失,他们一旦出现,所经地区受害尤为严重。
去年12月31日和今年元月1日,沙尘暴兄弟肆虐甘肃省河西走廊,兰州市出现浮尘,在他们的统治下,连白天开车都要开车灯呢。今年3月底以前,甘肃河西走廊和内蒙西部已出现沙尘天气9次之多。3月中旬,兄弟俩的踪影出现在距沙漠地区遥远的南京市,引起人们的恐慌。
沙尘暴兄弟气焰嚣张,甚至飘扬过海,登陆日本了,日本的电视新闻都在说:从中国来的6年来最大的一次沙尘暴袭击了日本的大部分地区。
沙尘暴兄弟对人类的危害这么大,不除不足以平民愤呀!我想发明一种机器,专门治理沙尘暴。当然,我的机器它并不是《西游记》中多闻天王的混元珠伞,能把花果山的猴子收拾得干干净净,而是一种能播撒绿色的机器。因为沙尘暴兄弟光靠挡是挡不住的,只有把他们消灭在“出生”的地方,才是治本的好办法。沙漠是沙尘暴兄弟的“出生地”,我发明的机器,能把他们困在沙漠里不能出来“作恶”。机器的形状象一个超级可乐瓶,里面装满了富于营养的物质和植物的种子,这种瓶子可以固定在飞机的肚子下面,飞到沙漠上空的时候,就通过操纵杆打开“瓶盖”,把营养物质和植物种子均匀地喷洒在沙漠表面,营养物质里面饱含植物生长所需的水分,经过科学家的特别配制,落到沙漠上后并不会马上被沙子吸收或蒸发掉,它会一直坚持到植物长大为止。我相信,过了不久沙漠上就会遍布绿色植物了。我的机器表面涂着漂亮的绿色,好像在暗暗地告诉着我们要保护环境。有了我发明的机器,沙尘暴兄弟这两个祸害人民的“罪犯”肯定被绳之以法了,哈哈!
当然,这只是我的幻想,现在真正地实现这个愿望还要等一段时间。所以,我们要从身边的一点一滴做起,从身边的小事做起,努力学习科学文化知识,将来有更多的发明创造,让大自然变得更加美丽!
谁都希望自己有一双炯炯有神的双眸,宛如夜空中闪亮的星星。而患了近视病后,那厚厚的眼镜片,像什么似的,显不出一点孩子的活泼和可爱。更看不出一点斯文 的气质。
那么怎样才能保护好自己的眼睛,预防近视呢?
首先要有正确的用眼姿势,同学们每天都要读书写字,有的人写字时,下巴搁在桌上,肩膀歪着,眼睛恨不得钻到纸里去,这样眼睛为了调节合适的距离,使肌肉得不到放松,晶状体凸度增大,长久之下,睫状体内的肌肉得不到放松,变凸的晶状体也不能恢复到正常状态,因此,眼睛就会看不清远处的东西,所以,我们一定要使用正确的用眼姿势,眼与书的距离要保持33厘米左右,千万不能躺着或走着看书哟!
其次要注意合适的光线,简单的说,就是不能太暗或太亮。否则会使散瞳缺少屈光度而造成近视。我想你一定经历过。
还有就是要注意劳逸结合,看书一小时后,就要向远方眺望一会,看看绿色的田野,一幢幢的楼房,以此来缓解一下眼睛的疲劳,千万不可立即看电视。
眼睛是宝贵的,如同我们的生命,我们一定要爱护它。眼睛是心灵的窗户,它展示着一个人的聪明、可爱、活泼。让我们积极的预防近视,让你的心灵之窗永远明亮。
