时间像沙漏里的沙子一样在慢慢的流逝,一个小时,两个小时,三个小时……
时间不知不觉得到了,我掏出手机赶紧给妈妈打电话,“嘟——,嘟——。您拨的电话暂时无法接通,请稍后再拨。”
霎时间,我的心里就感觉有一块大石头在压着。我焦急的在屋子里走来走去,快要吃饭了,可是我现在却一点也不饿。“怎么办!怎么办!”我急的满头大汗。就在这时候,手机QQ突然响了,我想一定是妈妈给我发的消息。我一打开手机,大惊失色。妈妈说今天去不了了。我呆呆的站在那里,久久不能平复心情。于是我回了一句“习惯了。”
可是我却突然意识到,我竟在无意中伤了妈妈的心。妈妈一定会心痛的。
第二天,妈妈再次说要带我去游泳。这时候我的心里已经不抱太大的希望了。到了中午,妈妈没有回来吃饭。我心想:这次晚上的计划肯定又要泡汤了,连中午饭都没来得及吃。晚上更有可能不去游泳。
到了时间,我还在犹豫要不要给妈妈打电话,就在我犹豫的时候“嘟!嘟!”我的手机响了,原来是妈妈我打的电话。只听电话那头传来亲切的声音“臭小,我去接你你做好准备。”
电话一挂,我突然意识到了,原来有时候母爱并不像你想象的那么简单,她是一种神奇并且伟大的爱。

篇19:初二关于地震的英语作文
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。
篇20:有关和时间赛跑初二
全文共 777 字
+ 加入清单我读小学的时候,我的外公去世了。外公生前最疼爱我。我无法排除自己的忧伤,每天在学校的操场上一圈一圈地跑着,跑得累倒在地上,扑在草坪上痛苦。
那哀痛的日子持续了很久,爸爸妈妈也不知道如何安慰我。他们与其欺骗我说外公睡着了,还不如对我说实话:外公永远不会回来了。
“什么是永远不会回来了呢?”我问。
“所有时间里的事物,都永远不会回来了。你的昨天过去了,它就永远变成昨天,你再也不能回到昨天了。爸爸以前和你一样小,现在再也不能回到你这么小的童年了。有一天你会长大,也会像外公一样一样老,有一天你度过了的你的所有时间,也会像外公一样永远不能回来了。”爸爸说
爸爸等于给我说了个谜。这个谜比“一寸光阴一寸金,寸金难买寸光阴”还让我感到可怕,比“光阴似箭,日月如梭”更让我有一种说不去的滋味。
以后,我每天放学回家,在庭院里看着太阳一寸一寸地沉进了山头,就知道一天真的过完了。虽然明天还会有新的太阳,但永远不会有今天的太阳了。
我看到鸟儿飞到天空,它们飞得很快呀。明天它们飞过同样的路线,也永远不是今天了。或许明天飞过这条路的,不是老鸟,而是小鸟了。
时间过得飞快,使我的小心眼里不只是着急,还有悲伤。有一天放学回家,看到太阳快落上了,就下决心说:“我要比太阳更快地回家。”我狂奔回去,站在庭院里喘气的时候,看见太阳还露着半边脸,我高兴地跳起来。那一天我跑赢了太阳。以后我常做这样的游戏,有时和太阳赛跑,有时和西北风比赛,有时一个暑假的功课我十天就做完了。那时我三年级的功课常把哥哥五年级的功课拿来做。每一次比赛胜过时间,我就快乐得不知道怎么形容。
后来的二十年里,我因此受益无穷。虽然我知道人永远跑不过时间,但是可以比原来跑快一步,如果加把劲,有时可以快好几步。那几步虽然很小很小,用途却很大很大。
如果将来我有什么要教给我的孩子,我会告诉他:假若你一直和时间赛跑,你就可以成功。
