+ 加入清单With the development of economy, there are more and more vehicles on the
streets. Governments at all levels have to do something to solve the problem of
heavy traffic in the city.
I would like to share with you some ideas about this problem: firstly, the
government should build more roads. This action can decrease the degree of
street congestion and make it possible for cars to run faster than ever before.
But each coin has two sides. If a city builds too many roads, the streets will
occupy much land. We will have little space used for other purposes. So
secondly, more special bus lines for public transportation should be added. Thus
people can go conveniently everywhere they like; they will not ride bikes or
drive cars. In this way, the number of cars and bikes on the road will be
greatly cut down.
As far as I am concerned, if we want to solve this problem, we should set
up an idea of public transportation first and give a priority to this idea in
our traffic work.

全文共 1006 字
+ 加入清单In modern society, the problem of heavy traffic has aroused a wide concern.
Concerning with this problem, different people hold different opinions. As far
as I am concerned, to solve this problem, we need to begin with the following
steps.
First, limiting the number of private cars is a significant step to solve
the problem of heavy traffic. Private car occupies a larger space and it is
responsible for traffic jam to a large extent. Less private cars will accelerate
the flow of traffic. Second, it is also a good means to open up the special
roads for buses. By doing this, the phenomenon that the buses block the street
when passengers get on or get off the buses will not occur again. At the same
time, it will upgrade the efficiency of buses. Finally, reinforcing punish
toward the over-speed cars and drunk driving so as to reduce the rate of traffic
accident, and then decrease traffic jam.
To put it in a nutshell, only we put the above advice into practice
together can we solve the problem of heavy traffic.

篇17:以岩石之松为主题的初二作文
全文共 1083 字
+ 加入清单我愿做高山岩石之松,不做湖畔河旁之柳。我愿在暴风雨中,艰苦的斗争中锻炼自己,不愿在平平静静的日子里度过自己的一生。
——雷锋
有人说,不经历风雨的人生不是完整的人生;有人说,平平淡淡的生活才是真;有人说……我问天下人,到底怎样的人生才算完整?怎样的人生才不算白过?天下人的回答千千万万,唯有奉献,不曾改变。
雷正兴,你认识吗?我想大家肯定不熟吧,那么,雷锋呢,你总该认识了吧。从小到大,雷锋一直是我们学习的标杆,雷锋精神一直指引我们前进的方向;雷锋叔叔已成为助人为乐的代名词……他,具有划时代意义;他,是永远的伟人,那么就让我们在这特殊的日子里来谈谈他的精神——奉献。
奉献,有人有情,有人无义。现在的社会是个文明的社会,可是却总是会有不文明的事发生,令人发指。这是一个真实的事件:一个不幸的小女孩被迎面而来的客车撞伤,那鲜红的液体瞬时间喷发,是那样的刺眼,可是马路上行人的匆匆脚步居然没为她停下,视而不见就是他们的态度。由于行人的无视,小女孩又再次被压了,在他惨痛悲绝的哭喊声中,终于一个清洁工人冲出马路,抱起她,送到了医院……一个视而不见,一个出手相助,不同的人,是不一样的结果。路上的行人,穿着华丽,却是心灵的魔鬼;清洁工人,看似卑微不起眼,但却是心灵的天使。
奉献,有人牺牲,有人存活。上帝是公平的,在你救了一个人的同时,往往会夺走你的生命。三个大学生奋不顾身跳入河中就落水阿姨,最终阿姨活下来了,可是上帝却夺走了三个大学生的命。他们是祖国的未来啊,他们的人生才刚刚起步啊,他们什么事都还没开始做呢……但是他们离开了,是什么驱使他们这么做呢?是责任。对他人的责任,对社会的责任……他们的奉献精神大义凛然。“死,有轻于鸿毛,亦有重于泰山”而他们就是泰山,让我们永远敬仰!
奉献,我们的使命,祖国的未来。传承民族精神,发扬民族精神,那是我们当代青年的使命,我们应该学习雷锋精神,学做雷锋事情,成为雷锋新人。如果一个人的核心是灵魂,那么一个祖国的核心也该是灵魂把。通过奉献,我们的灵魂纯净了许多,那么,这么多的我们组成的国家的灵魂该是更高尚把!如果一个精神代表国家的未来,那么我想,中国的未来将是无可限量,祖国啊,我祝福你!
“人的生命是有限的,可我要用有限的生命,投入到无限的为人民服务中去。”这是雷锋叔叔的人生写照,也是我们前进的引导,我们也要用有限的生命,投入到无限的为人民服务中去。雷锋叔叔虽然早早离开,但那是他的精神不会泯灭。现在,以后,未来,将会有越来越多的人学习他,‘成为’他。啊,他,一个巨大的伟人!
无私奉献,默默付出,我愿做一棵无名的小草,装点这广袤的大地……

全文共 2482 字
+ 加入清单After 5.12 earthquake struck sichuan province since 2008, we, I was so frightened by an earthquake, I felt the earthquake many houses will be apart, can let many people lost their lives, is one of the worlds most terrible disaster. Today I saw "China childrens encyclopedia, really know anything about earthquake.
It turns out that the earthquake happened all of a sudden the vibration phenomenon, like the wind, rain, is a kind of common natural phenomena. Vibrations in the earth, in fact, very frequently, probably every 30 seconds there will be time, but most of them are very ease, people did not feel. We can feel the earthquake is due to the relative movement between earths tectonic plates, rock is squeezed, produce a huge amount of energy to make rock failure in an instant, or make originally the already existing fracture activity, suddenly release a large amount of energy, and some of the energy to the earths surface, make the earth trembling violently, causing strong earthquake. Started happening earthquake site is called the source, the source above the ground is called the epicenter, the ground of the devastating earthquake is the most strong place is called the magistoseismic area, while the magistoseismic area often is the place where the epicenter. When the earthquake occurred, the source of shock wave in the earths crust to all directions called seismic waves. Seismic waves hit the ground, the result will be a disaster.
We Chinese people are very smart, as early as the eastern han dynasty, there is a man named zhang heng scientists invented to measure the earthquake Hou Feng seismograph, and our modern scientists are generally measured the spread of seismic wave speed with the help of a seismograph, the place and time of the earthquake.
Know the earthquake knowledge, learning even before the earthquake early warning and self protection method, I think, to know that knowledge is very useful for our own.
自从2008年我们四川发生5.12大地震之后,我就特别害怕地震,我觉得地震会震垮很多房屋,会让许多人失去生命,是世界上最可怕的灾难。今天我看了《中国少年儿童百科全书》后,才真正知道地震是怎么回事。
原来,地震是突然间发生的大地震动现象,就像刮风、下雨一样,是一种很普遍的自然现象。地球上的震动实际上非常频繁,大概每30秒种就会有一次,但大多数都非常缓和,人们都没有感觉。我们能感觉到的地震是由于地球板块之间产生相对运动,岩石层受到严重挤压,产生巨大的能量使岩石在瞬间发生断裂,或者使原来已经存在的断裂突然活动,释放出大量能量,而其中一部分能量传到地球表面,使大地剧烈地颤动,从而引起强烈地震。地震开始发生的地点称为震源,震源上方的地面称为震中,破坏性地震的地面最烈处称为极震区,而极震区往往就是震中所在的地方。地震发生时,震源发出的在地壳中传向四面八方的冲击波称为地震波。地震波冲击到地面,就会引发灾难。
我们中国人非常聪明,早在东汉时期,就有一位叫张衡的科学家发明了用来观测地震的侯风地动仪,而我们现代的科学家也一般都借助地震仪来测量地震波的传播速度,判断地震发生的地点和时间。
知道了地震知识以后,还要学习地震发生前的提前预警和自我保护方法,我想,了解到这些知识对我们自己是非常有用的。
