星期天,我在爸爸的帮助下,上网查了一下西安三月份前半个月的空气质量,一查,让我大吃一惊,我发现其中国重度污染有六天,轻度污染有两天,中度污染有七天。
原来我们生活在这样的环境下,我问爸爸:“雾霾和沙尘对人体有什么危害吗?”爸爸和我查阅了一下网上的资料,原来,雾霾和沙尘的危害非常大,雾霾会导致传染病扩散和多种疾病发生,给人体健康带来较大的危害。沙尘也会危害到人们的身体健康,还给人类出行带来很大的不便。
我又查了一下造成雾霾和沙尘的原因,原来大气空气气压低,空气不流动是主要因素,空气不流动是空气中的微小颗粒聚集在一起,漂浮在空中,由于地面灰尘大,空气温度低,地面的人和车辆是灰尘搅动起来……沙尘是一种风雨沙的相互作用的危害性天气现象,它的形成与地球温室效应、植被破坏、物种灭绝、气候异常等有着不可分割的关系。他还分为沙尘暴、浮尘、强沙尘……
我想我们不应该无节制开采自然资源,不应该随意砍伐树木,有车的人尽量少开车,多做公交车和骑自行车,绿色出行。灯泡尽量用节能灯,少开空调,大家要给街道多洒水。不随地乱扔垃圾,多植树造林,保护我们的地球。
好的文章动静结合、张弛有度有节奏感。句式也是一样,要有变化性,这不仅能使文章更生动,也是语言表达方式的需要和表达能力的体现。句式的`变化,主要是要注意两点:
● 不要从头至尾使用一种句型。
● 长短句结合。
由于语言功底的欠缺和惯用思维,很多人写的文章一种句式到头,如:
I think …
I hope…
He does it.
He will take it
这样的文章虽然意思表达出来了,却显得呆板,欠生动。解决的办法是:
1.间或使用主从复句。
Because he is very much determined, he will carry it out this time. (原因
比较:He is very much determined. He will carry it out this time.
2.使用分词结构句。
The weather being fine, a large number of people went sightseeing.
比较:The weather is fine. A large number of people went sightseeing.
Africa is the second largest continent, its size being about three times that of China.
比较:Africa is the second largest continent. Its size is about three times that of China.
3.使用不定式句。
To be or not to be, that is a question. (莎士比亚
To study or not to study, that is much different.(引申
To do it well, you must plan it well.
比较:You want to do it well. And you must plan it well.
4.倒装句
Only when we fully recognize its importance can we have control of its essence.
比较:After we fully recognize its importance, we can have control of its essence.
No sooner had he arrived home than it began to rain.
比较:He arrived home. And it began to rain.
5.失衡句
whether or not he will come is still unknown to all the people present.
比较:No one present knows whether he will come or not.
That he has done it all by himself is known to everyone.
比较:Everyone knows that he has done it all by himself.
当然,句子并不是越长越好,也不是越复杂水平就越高。凡事皆有度。太多长句的堆砌让人觉得是买弄。有时侯,一个短小精辟的句子可以起到画龙点睛的作用。特别是在文末段尾。比如:
●As a creature, every one knows.
●Actions speak louder than words.
●Practice makes perfect.
Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.
Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.
Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.
In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day
The components that make up haze may have negative effect on people's health especially that of the children and the elderly. Also not excluded are those who have certain diseases such as asthma, allergy, and pneumonia and lung disease. Workers working in the open air have a high risk in their health.
组件构成烟雾可能对人们的健康有负面影响特别是儿童和老人。也不排除是某些疾病如哮喘、过敏、肺炎和肺部疾病。工人工作在露天有很高的.风险在他们的健康。
比如网络它会让我们的身心都沉浸上去;跳山羊它会让我们的身体受到伤害;斗鸡它会让我们摔跤,轻的会破皮,重的.可能会骨折。
网游它会让我们的心沉浸在网络的危害中,所以我们要主动去做一些事情——戒掉’网瘾‘。首先要主动避开,与其被电脑诱惑,不如主动把家里的电脑搬走;放学路过网吧,赶紧绕行;听到同学谈论网游就转身离开。另外转移注意力也很重要。
跳山羊的危害也很大,它会让我们的身体受到伤害,如:后脑勺。脖子等部位,要是你这里摔了,那里摔了,通的人可不是别人,而是你自己,我们班就发生过这种事情。九月二十六日,下午第三节课,讲台前面站了好多人,是怎么回事?原来都是跳山羊惹的祸,站在前面的同学一下课就去玩跳山羊,被老师发现了,全被狠狠地批评并保证以后在不玩跳山羊了。
斗鸡它会让我们摔跤,轻的会破皮,重的可能会骨折。父母可怖希望你们摔摔哪了,摔摔这里吧!父母可是希望你们健健康康的。
每一种游戏都有它的危害,每一种游戏都要控制的去玩,可不能沉浸在游戏里面啊!
但是,垃圾远远不止这些,医院里有医疗垃圾:水银、针管、针头、吊瓶、纱布等;建筑工地有建筑垃圾:造房子产生的渣土、弃土、弃料、砖头登;小路两边有植物垃圾:枯萎的花儿、落叶、菜叶等。看似小小的垃圾,分分散散,要是全部都结合起来,对人类的危害可真不小。
曾经在路上看到这一幕:路的.两边全都是建筑垃圾:砖头,钢筋,还夹杂着红色的垃圾袋,沿着这条路一直走,还没有走几步,鞋子上就已经沾满了泥土,沾满了灰尘。周围没有建筑,垃圾随处而堆,很少有行人来往,没有绿色的生机,建筑垃圾给这一块地区蒙上了一层灰色的布,一阵风吹过,灰尘使我的眼睛睁不开,过了许久,才敢把眼睛睁开,但眼睛还是不舒服。真是“垃圾城”啊!
曾经在路边看到这一幕:一堆泥土上,长了一颗“缺乏营养”的树,“枯藤老树昏鸦”,在阳光的照耀下,只看见几根又黑又细的枝干,那泥土上铺满了建筑垃圾,向后看去,原来,那里是建筑垃圾场,而那一颗树,则是小小的角落的不显眼的一棵枯死的树。
曾经在一块地的中央看到这一幕:一位40多岁的男士,开着卡车,车厢内装着砖头,钢筋等建筑垃圾。那卡车正向这边开过来。紧跟着车子后面的是厚厚的灰尘,厚到只看见灰尘,后面的场面全都被灰尘给“淹没”了。但是,这种厚厚的灰尘并没有引起死机的注意,那卡车仍然在一车一车的倾倒。
曾经的建筑垃圾,今天的建筑垃圾,未来的建筑垃圾,这些“没有价值的垃圾”将何去何从?
垃圾,是我们身边的危害,影响我们的工作、生活等方方面面,我们要采用正确的方法进行处理,共同保护我们美好的家园。
