30秒等于0.5分;解题过程:1分钟=60秒;30/60=0.5分。
分钟表示时间长度,英语:minute,原意是“微小”的意思,也表示min(多见于数学用语)。
换算:一天=1440分钟 ,1小时=60分钟 ,1分钟=60秒;
一刻=15分钟,一字=5分钟。
秒是国际单位制中时间的基本单位。
国际单位制词头经常与秒结合以做更细微的划分,例如ms(毫秒,千分之一秒)、μs(微秒,百万分之一秒)和ns(纳秒,十亿分之一秒)。
虽然国际单位制词头虽然也可以用于扩增时间,例如Ks(千秒)、Ms(百万秒)和Gs(十亿秒),但实际上很少这样子使用,大家都还是习惯用60进制的分、时和24进制的日做为秒的扩充。

短于秒
1、毫秒
毫秒是一种较为微小的时间单位,是一秒的千分之一(0.001秒),简称ms。典型照相机的最短曝光时间为一毫秒。一只家蝇每三毫秒扇一次翅膀;蚊子二十毫秒振翅一次;蜜蜂则每五毫秒扇一次。由于月亮绕地球的轨道逐渐变宽,它绕一圈所需的时间每年长两毫秒。
在计算机科学中,10毫秒的间隔称为一个jiffy。
2、微秒
微秒(microsecond)即百万分之一秒(10的负6次秒),简称μs。光在这个时间里可以传播300米,大约是3个足球场的长度,但是海平面上的声波只能传播1/3毫米。高速的商业频闪仪闪烁一次大约持续1微秒。一筒炸药在它的引信烧完之后大约24微秒开始爆炸。
3、纳秒
纳秒(nanosecond)即一秒的10亿分之一(10的负9次秒),简称ns。常用作内存读写速度的单位。光在真空中一纳秒仅传播30厘米(不足一个步长)。个人电脑的微处理器执行一道指令(如将两数相加)约需2至4纳秒。另一种罕见的亚原子粒子K介子的存在时间为12纳秒。
4、皮秒
皮秒(picosecond)即纳秒的千分之一(10的负12次秒),简称ps。最快晶体管的运行以皮秒计。一种高能加速器产生的罕见亚原子粒子b夸克在衰变之前可存在1皮秒。室温下水分子间氢键的平均存在时间是3皮秒。

秒的起源:
汉朝以前,“时”指季节,“一时”相当于现在的一季。一年有四季,所以一年又叫“四时”。汉朝以后,“时”不再表示季节,而是用来表示计算时间的单位了。
当时,人们把一天平均分成12个“时”,“一时”等于现在的两个小时,人们习惯把这个“时”称为“时辰”。在一些古典书籍中,我们也经常会看到“时辰”这两个字,有不少人误认为一个时辰就是现在的一个小时,其实这是不正确的。
像古代表示夜间时间的“一更天”、“二更天”的“更”就是指时辰,一更到二更,二更到三更都是相隔两个小时。
后来,人们又把一天平均分成24份,每份仍用“时”来表示。这时的“一时”就是现在的一个小时,只相当于过去(汉朝以后)“一时”或“一个时辰”的一半,所指的时间缩短了。
接着,人们又把一小时分成60等份,每份的时间叫1分,把1分又分成60等份,每份的时间叫1秒。这样,时、分、秒就确定下来了。

小时=时,英文单词为hour,通常简写为字母“h”。如1小时简写为“1h”分钟=分;英文单词为minute,通常简写为字母“m”。如2分钟简写为“2min”秒,英文单词为second,通常简写为字母“s”。如3秒简写为“3s”除此之外,生活中常用的时间单位(简写)还有:毫秒(ms)、分(min)、小时(h)、日(d)、月(m)、年(y)等。其中1 毫秒(ms)= 0.001 秒(s),1分(min)=60秒(s),1小时(h)=60分(min),1日(d)=24小时(h),(通常情况下)30日(d)=1月(m),12月(m)=1年(y)。扩展资料:在国际单位制(SI)中,时间的基本单位是秒,符号s,在1967年召开的第13届国际度量衡大会对秒的定义:铯-133的原子基态的两个超精细能阶间跃迁对应辐射的9,192,631,770个周期的持续时间。这个定义提到的铯原子必须在绝对零度时是静止的,而且在地面上的环境是零磁场。在这样的情况下被定义的秒,与天文学上的历书时所定义的秒是等效的。参考资料:时间_百度百科2023-07-20 05:37:491
一秒等于多少毫秒
一秒等于1000毫秒,等于10的15次方皮秒。时间是一个较为抽象的概念,是物质的运动、变化的持续性、顺序性的表现。时分秒都是我们常用的时间单位,1秒的时间很短但是很有价值,毫秒则是更小的时间单位。一秒等于多少毫秒1秒=1000毫秒,时间单位秒是国际单位制中时间的基本单位,符号是s。有时也会借用英文缩写标示为sec。时间单位换算1秒=1000毫秒(ms)1毫秒=1/1,000秒(s)1秒=1,000,000微秒(μs)60秒=1分钟时间的换算是所有单位换算中最复杂的。1年等于365天,1年等于12个月,1个月等于30天,这些都是根据地球、月亮公转决定的,不以人的意志为转移,只不过各个国家、各个朝代有的使用太阳历,有的太阴历,还有的阴阳历所导致略有不同。但一天之内的时间细分却绝对是人为的。古代中国1天等于12个时辰(其他国家也是),这跟地支相对应。地支为什么是12个,而不是11个、13个,也不是古代人拍脑袋想出来。天文中,有很多与12有关的数据,比如,木星每公转一周地球公转12周,地球每公转一周月球公转12周。出于这个心理作用,古代人就把一天平分为了12份。但人们发现,1天12个时辰的划分不够精细化,于是便改为24个小时,正好是12的2倍。1天24个小时是英国人发明的,刚好与地球划分为24个时区相吻合,1个时区就是15°。1小时等于60分钟,1分钟等于60秒,这大概是跟9000年前的苏美尔人那里学的。古代需要对士兵分组,需要分地,需要分粮食,为了好分,苏美尔人发明了60进制,因为60可以被2、3、4、5、6、10整除或分组。后来两河流域的巴比伦人在计时上学习了60进制。后来,全人类广泛推广并使用10进制,但人们早已经习惯了用60进制计算时间,习惯了也就懒得改了。1秒再细分的话就采用10进制了,例如,1秒等于1000毫秒。2023-07-20 05:38:581

湿度的单位是什么?
%RH是相对湿度的单位。相对湿度(Relative Humidity ),用RH表示。表示空气中的绝对湿度与同温度和气压下的饱和绝对湿度的比值,得数是一个百分比。(也就是指某湿空气中所含水蒸气的质量与同温度和气压下饱和空气中所含水蒸气的质量之比,这个比值用百分数表示。例如,某机房平常所说的湿度为60%,即指相对湿度。)相对湿度是单位体积空气内实际所含的水气密度(用d1 表示)和同温度下饱和水气密度(用d2 表示)的百分比,即RH(%)= d1/ d2 x 100%。另一种计算方法是:实际的空气水气压强(用p1 表示)和同温度下饱和水气压强(用p2表示)的百分比,即RH(%)= p1/ p2 x 100%。扩展资料当一个地方没有明显的干空气或湿空气进来时,实际含水量是相对稳定少变的,但是理论最大含水量,这个分母项是会变的。空气温度越高,大气可承载的水汽量越大。因此当下午气温达到最高时,分母项最大,夜间-清晨气温最低时,分母项最小,这样一天中,相对湿度就会经常性的过山车。实际生活中,用的吹风机,就是通过加热空气,使得局部的理论最大含水量提升,降低相对湿度,加快头发变干,当然风也会加快水分蒸发。另一个重要推论就是,因为夜间-清晨气温低,导致相对湿度分母项低,因此空气相对湿度大,更容易达到饱和,出现大雾。因此雨后夜间放晴,或者晴朗的夜间,吹起南风或东风输送水汽,都是很容易见到大雾的形势,但到了白天光照加热,相对湿度分母项上升,相对湿度也就下来,雾就散了。参考资料来源:百度百科-相对湿度2023-07-20 05:40:411

Some said that tea and coffee were harmful to humans and they could cause people to die. In Sweden(瑞典),King Gustaf Ⅲ decided to find out whether or not this was true. It happened that there were two brothers in prison at that time. They were twins and were almost exactly alike in every way. They had both been sentenced to death(判处死刑). The King decided to let them live if one of the men agreed to drink several cups of tea each day and the other several cups of coffee. Both brothers lived many years without problems of any kind. At last,the brother who had drunk tea every day died at the age of 83,the other died a few years later. Because of the experiment,tea and coffee got accepted(接受) and became popular as drink in Sweden,and it is one of the many countries of the world where much tea and coffee is drunk today. 46.

湿度的单位符号
您好,您是不是想问湿度的单位符号有哪些?湿度的单位符号有以下两种:1、相对湿度的单位符号为“%RH”,其中“%”表示百分比,“RH”表示相对湿度。2、绝对湿度的单位符号为“g/m3”,其中“g”表示克,“m3”表示立方米。相对湿度是指空气中实际水蒸气压与该温度下饱和水蒸气压之比,通常用百分数表示。例如,当空气中的水蒸气压达到该温度下饱和水蒸气压的50%时,相对湿度为50%RH。绝对湿度是指单位体积空气中所含水蒸气的质量,通常用克/立方米表示。例如,当单位体积空气中所含水蒸气的质量为10克时,绝对湿度为10g/m3。2023-07-20 05:41:261
湿度单位
湿度有三种基本形式,水汽压、相对湿度、露点温度。水汽压表示空气中水汽部分的压强,单位以百帕(hPa)为单位,取小数一位;相对湿度用空气中实际水汽压与当时气温下的饱和水汽压之比的百分数表示,取整数;露点温度,单位用摄氏度(℃)表示,取小数一位。 湿度概念 湿度,一般在气象学中指的是空气湿度,它是空气中水蒸气的含量。空气中液态或固态的水不算在湿度中。不含水蒸气的空气被称为干空气。由于大气中的水蒸气可以占空气体积的0%到4%,一般在列出空气中各种气体的成分的时候是指这些成分在干空气中所占的成分。 空气的干湿程度,或表示含有的水蒸气多少的物理量,称为湿度。单位体积的空气中含有的水蒸气的质量叫作绝对湿度。由于直接测量水蒸气的密度比较困难,因此通常都用水蒸气的压强来表示。空气的绝对湿度并不能决定地上水蒸气的快慢和人对潮湿程度的感觉。人们把某温度时空气的绝对湿度和同温度下饱和气压的百分比叫作相对湿度。 湿度基本形式 湿度有三种基本形式,即水汽压、相对湿度、露点温度。 水汽压(曾称为绝对湿度)表示空气中水汽部分的压强,单位以百帕(hPa)为单位,取小数一位; 相对湿度用空气中实际水汽压与当时气温下的饱和水汽压之比的百分数表示,取整数; 露点温度是表示空气中水汽含量和气压不变的条件下冷却达到饱和时的温度,单位用摄氏度(℃)表示,取小数一位。配有湿度计时还可以测定相对湿度的连续记录和最小相对湿度。2023-07-20 05:41:351
湿度的单位是什么?
水汽压(曾称为绝对湿度)表示空气中水汽部分的压强,单位以百帕(hPa)为单位,取小数一位;相对湿度用空气中实际水汽压与当时气温下的饱和水汽压之比的百分数表示,取整数;日常生活中所指的湿度为相对湿度,%rh表示。总言之,即气体中(通常为空气中)所含水蒸气量(水蒸气压)与其空气相同情况下饱和水蒸气量(饱和水蒸气压)的百分比。空气的干湿程度,或表示含有的水蒸气多少的物理量,称为湿度。单位体积的空气中含有的水蒸气的质量叫作绝对湿度。由于直接测量水蒸气的密度比较困难,因此通常都用水蒸气的压强来表示。扩展资料绝对湿度一般其单位是克/立方米。最大限度是饱和状态下的最高湿度。它只有与温度一起才有意义,因为空气中能够含有的湿度的量随温度而变化,在不同的温度中绝对湿度也不同,因为随着温度的变化空气的体积也要发生变化。但绝对湿度越靠近最高湿度,它随温度的变化就越小。一台湿度计正在记录相对湿度相对湿度是绝对湿度与最高湿度之间的比,它的值显示水蒸气的饱和度有多高。相对湿度为100%的空气是饱和的空气。它是50%的空气含有达到同温度的空气的饱和点的一半的水蒸气。参考资料来源:搜狗百科-湿度2023-07-20 05:41:441

问题一:代表湿度的那个单位符号 一般是指相对湿度,符号为 %RH。 相对湿度(Relative Humidity),空气有吸收水分的特征,湿度的概念是空气中含有水蒸气的多少.它有三种表示方法: 第一是绝对湿度,它表示每立方米空气中所含的水蒸气的量,单位是千克/立方米; 第二是含湿量,它表示每千克干空气所含有的水蒸气量,单位是千克/千克u30fb干空气; 第三是相对湿度,表示空气中的绝对湿度与同温度下的饱和绝对湿度的比值,得数是一个百分比.(也就是指在一定时间内,某处空气中所含水汽量与该气温下饱和水汽量的百分比.) ; 相对湿度用RH表示.相对湿度的定义是单位体积空气内实际所含的水气密度(用d1 表示)和同温度下饱和水气密度(用d2 表示)的百分比,即RH(%)= d1/ d2 x 100%;另一种计算方法是:实际的空气水气压强(用p1 表示)和同温度下饱和水气压强(用p2表示)的百分比,即RH(%)= p1/ p2 x 100%。 问题二:湿度应该用什么单位 空气湿度是指空气潮湿的程度,可用相对湿度(RH)表示,它是用露梗温度来定义的。相对湿度是指空气实际所含水蒸气密度和同温下饱和水蒸气密度的百分比值。人体在室内感觉舒适的最佳相对湿度是,49%~51%,相对湿度过低或过高,对人体都不好。 问题三:什么是湿度?单位是什么? 表示大气干燥程度的物理量。在一定的温度下在一定体积的空气里含有的水汽越少,则空气越干燥;水汽越多,则空气越潮湿。空气的干湿程度叫做“湿度”。在此意义下,常用绝对湿度、相对湿度、比较湿度、混合比、饱和差以及露点等物理量来表示;若表示在湿蒸汽中液态水分的重量占蒸汽总重量的百分比,则称之为蒸汽的湿度。 【综述】 空气的温度越高,它容纳水蒸气的能力就越高。虽然水蒸气可以与空气中的部分成分(比如悬浮的灰尘中的盐)进行化学反应,或者被多孔的粒子吸收,但这些过程或反应所占的比例非常小,相反的大多数水蒸气可以溶解在空气中。干空气一般可以看作一种理想气体,但随着其中水汽成分的增高它的理想性越来越低。这时只有使用范德华方程才能描写它的性能。 理论上“空气中的水蒸气饱和”这个说法是不正确的,因为空气中的水蒸气的饱和度与空气的成分本身无关,而只与水蒸气的温度有关。在同一温度下真空中的水蒸气的饱和度与空气中的水蒸气的饱和度实际上是一样高的。但出于简化一般人们(甚至在科学界)使用“空气中溶解的水蒸气”或“空气中的水蒸气饱和”这样的词句。在这篇文章中我们也使用这些常用的词句。 假如饱和的空气的温度降低到露点以下和空气中有凝结核(比如雾剂)的话(在自然界一般总有凝结核存在),空气中的水就会凝结。云、窗户玻璃和其它冷的表面上的凝结水、露和雾、人在冷空气中哈出的汽等等许多现象就是这样形成的。偶尔(或在实验室中人工造成的)水蒸气可以在露点以下也不凝结。这个现象叫做过饱和。 空气中水蒸气的溶解量随温度不同而变化。一立方米空气可以在10摄氏度下溶解9.41克水,在30摄氏度下溶解30.38克水。 【测量】 湿度计多个量被用来表示空气的湿度。下面列出最常用的: u30fb蒸汽压 u30fb绝对湿度 u30fb相对湿度 u30fb比湿 u30fb露点 用来测量湿度的仪器叫做湿度计。 ▲绝对湿度 绝对湿度是一定体积的空气中含有的水蒸气的质量,一般其单位是克/立方米。绝对湿度的最大限度是饱和状态下的最高湿度。绝对湿度只有与温度一起才有意义,因为空气中能够含有的湿度的量随温度而变化,在不同的高度中绝对湿度也不同,因为随着高度的变化空气的体积变化。但绝对湿度越靠近最高湿度,它随高度的变化就越小。 下面是计算绝对湿度的公式: e m ρw =───=── Rwu30fbT V 其中的符号分别是: e 蒸汽压,单位是帕斯卡 Rw 水的气体常数=461.52J/(kg K) T 温度,单位是开尔文 m 在空气中溶解的水的质量,单位是克 V 空气的体积,单位是立方米 ▲相对湿度 一台湿度计正在纪录相对湿度相对湿度是绝对湿度与最高湿度之间的比,它的值显示水蒸气的饱和度有多高。相对湿度为100%的空气是饱和的空气。相对湿度是50%的空气含有达到同温度的空气的饱和点的一半的水蒸气。相对湿度超过100%的空气中的水蒸气一般凝结出来。随着温度的增高空气中可以含的水就越多,也就是说,在同样多的水蒸气的情况下温度升高相对湿度就会降低。因此在提供相对湿度的同时也必须提供温度的数据。通过相对湿度和温度也可以计算出露点。 以下是计算相对湿度的公式: ρw e s φ =───u30fb100%=─u30fb100%=─u30fb100% ρw,max E S 其中的符号分......>> 问题四:绝对湿度的单位 绝对湿度的单位就是水蒸气压的压强,千帕、兆帕或毫米汞柱。 问题五:湿度的计量单位是什么? 目前用来衡量湿度大小的单位尚不统一,有的单位定义不够确切,各有关手册所列湿度的量值互有出人,关于真实气体偏离理想气体的修正向题也没有很好地解决,本文试图对这些问题进行探讨。 : p―湿气体的压力(Pa); ps―湿气体中所含水蒸汽的分压力(Pa); p、s一一与湿气体温度t相对应的饱和蒸汽压力(Pa); p、sL―与湿气体露点温度tL相对应的饱和蒸汽压力(P。); p。―标谁状况的压力,101325Pa; P:―干气体的临界压力(P。); P。―湿气体的临界压力(Pa); 常用温度单位换算表露点绝对 湿度 g/m3体积比 ppmV重量比 在空气中 ppmW相对湿度 (20℃)% 露点绝对 湿度 g/m3体积比 ppmV重量比 在空气中 ppmW相对湿度 (20℃)%℃0F℃0F-70-940.002072.51.640.001-10142.062560159011-60-760.00857116.590.0050324.846020380026-50-580.03123924.20.0210509.2112100772952-40-400.10212779.10.05206818.523100 100-30-220.3013762340.2308636.641800 -20-40.816102063544010458.5730002023-07-20 05:42:031

常用的湿度单位是什么
常用的湿度单位是RH。空气湿度,可用相对湿度(RH)表示,它是用露点温度来定义的。相对湿度是指空气实际所含水蒸气密度和同温下饱和水蒸气密度的百分比值。人体在室内感觉舒适的最佳相对湿度是,49%~51%,相对湿度过低或过高,对人体都不好。湿度的用途:下雨的时候,空气湿度是非常大的在气象学和水文学中湿度是决定蒸发和蒸腾的重要数据。它对不同的气候区的产生起决定性的作用。大气中的水蒸气在水循环过程中也是必不可少的。通过水蒸气水可以很快地在地球表面运动。水在大气中形成降水、云和其它现象,它们决定了地球的气象和气候。而在天气预报中,更常用到相对湿度。它反映了降雨、有雾的可能性。在炎热的天气之下,高的相对湿度会让人类(和其他动物)感到更热,因为这妨碍了汗水的挥发。人类可以从而制定出酷热指数。2023-07-20 05:40:131

湿度的单位是什么
湿度的单位是单位是克/立方米。在一定的温度下在一定体积的空气里含有的水汽越少,则空气越干燥;水汽越多,则空气越潮湿。空气的干湿程度叫做“湿度”。在此意义下,常用绝对湿度、相对湿度、比较湿度、混合比、饱和差以及露点等物理量来表示;若表示在湿蒸汽中水蒸气的重量占蒸汽总重量(体积)的百分比,则称之为蒸汽的湿度。人体感觉舒适的湿度是:相对湿度低于70%。湿度三种基本形式:1、水汽压(曾称为绝对湿度)表示空气中水汽部分的压强,单位以百帕(hPa)为单位,取小数一位;2、相对湿度用空气中实际水汽压与当时气温下的饱和水汽压之比的百分数表示,取整数;3、露点温度是表示空气中水汽含量和气压不变的条件下冷却达到饱和时的温度,单位用摄氏度(℃)表示,取小数一位。配有湿度计时还可以测定相对湿度的连续记录和最小相对湿度。2023-07-20 05:39:541
湿度单位是什么?
ρw – 绝对湿度,单位是克/立方米。湿度(Humidity)表示大气干燥程度的物理量。在一定的温度下在一定体积的空气里含有的水汽越少,则空气越干燥;水汽越多,则空气越潮湿。空气的干湿程度叫做“湿度”。在此意义下,常用绝对湿度、相对湿度、比较湿度、混合比、饱和差以及露点等物理量来表示;若表示在湿蒸汽中水蒸气的重量占蒸汽总重量(体积)的百分比,则称之为蒸汽的湿度。人体感觉舒适的湿度是:相对湿度低于70%。相关信息:空气的干湿程度,或表示含有的水蒸气多少的物理量,称为湿度。单位体积的空气中含有的水蒸气的质量叫作绝对湿度。由于直接测量水蒸气的密度比较困难。因此通常都用水蒸气的压强来表示。空气的绝对湿度并不能决定地上水蒸气的快慢和人对潮湿程度的感觉。人们把某温度时空气的绝对湿度和同温度下饱和气压的百分比叫作相对湿度。2023-07-20 05:39:411

有关梦想的英语演讲稿大全
【 #英语资源# 导语】演讲又叫讲演或演说,是指在公众场所,以有声语言为主要手段,以体态语言为辅助手段,针对某个具体问题,鲜明,完整地发表自己的见解和主张。以下是 整理的内容,希望对您有所帮助。 1.有关梦想的英语演讲稿大全 Hello, everyone. The topic of my speech today is my dream. With dreams, birds can soar between the sky and white clouds; With a dream, fish can roam deeper in the sea... My dream is to be a leader. If my dream comes true, my school environment as headmaster must be very beautiful. There is a clear pond in the school. There are many lotus flowers in the pond, pink and light white. They are very beautiful. There will also be a long stream, surrounded by lawn, green grass and wild flowers in full bloom. Students can rest and play here after class. I think they will like it very much, because it"s like staying in nature here. If my dream comes true, there will be many interesting things in my school as headmaster. For example, we have special robots. They can manage and educate those naughty children and let them know to study hard. We also have a special gym. No matter whether it"s sunny or rainy, our students can have PE classes here. There is also a special laboratory. Every time they have a science class, every student can do the experiment himself, so that they will learn better! If my dream comes true, the students in the school where I am the principal are also very lovely. They take classes very seriously and do their homework very well. They all know to study hard. And they are very polite and like to help others very much. All the other students in my school are the best! With a dream, you can grow up happily. Students, do you have a dream? Thank you. My speech is over. 2.有关梦想的英语演讲稿大全 Dear leaders, teachers and students hello everyone! Everyone has a "house" he wants in his heart, which is a dream. If there is no dream, life has no direction and can only drift with the tide. It is like a ship that can"t find a navigation mark and can never find the right track. you bet. Perhaps he once spoke his ideal ambition to his young self without hesitation; Or maybe in retrospect, I will laugh at my ignorance at that time. In fact, at that time, the dream has planted seeds in the bottom of my heart, waiting for the sweat of hard work to irrigate and grow it. Occasionally, I have leisure to lean in the shade of the tree and watch the light and shadow obscured by leaves on the ground turn dark and bright. I can"t help feeling the rapid speed of time. If you carefully stare at the clock, you will find that one second actually passes quickly. Playing between your fingers, you have passed half of your life"s learning career. At ordinary times, I bury myself in reading for competition, but I don"t know that the original dream has been forgotten; And those who indulge in all things can"t extricate themselves for a long time, and finally let the dark clouds cover their eyes and lose the direction they should go. In the words of celebrities: "sometimes, we don"t know until we fail that we are only a small step away from success; and the reason for failure is often that we don"t have firm faith and stick to our dreams." Campus is the place where dreams begin and go. In fact, each of our students is very lucky to grow up and study in the cradle of such a 100 year old school with countless talents. Here we have gained friendship, knowledge, experience and the golden stone that paves the way for us to realize our dreams. Work hard with your partners, share your little dreams with your partners, and cooperate with your partners for your dreams... Maybe many students around you have lost their minds. They are not without dreams or smart minds, but in front of many seemingly insurmountable obstacles, their fear makes them vulnerable; Maybe they will always complain about the tiredness and hardship of learning and complain about a lot of unfairness. In fact, the school has given us the same learning environment and conditions, but some people know how to cherish and use the resources of the school to work hard for their ideals, while others do not cherish such learning opportunities. They are getting farther and farther away from success, and even their dreams have fallen. Friends, pick up the original dream! As long as you have sincerity, ambition, unswerving ideals and struggle, you can overcome even the greatest difficulties. Dreams only belong to those who are willing to work hard for their dreams step by step. Pick up the original dream and bring success closer to us. My speech is over, thank you! 3.有关梦想的英语演讲稿大全 Dear teacher and classmate In life, everyone has his own dream. Some people dream of being a free bird; Some people dream of being a scientist; Some want to be a singer... My dream is to grow up and be a teacher. I want to be a teacher when I grow up. In spring, I will take my students on field trips, fly kites and feel the fun of spring. In summer, I will take my students swimming, encourage them and let them learn to swim. In autumn, I will take them to see the farmer uncle harvest wheat, take them to eat fruit and collect plant specimens. In winter, I will take them to snowball fights and make snowmen, so that those students who are afraid of the cold can go to snowball fights, make snowmen and row ice like other students, so that they can all feel the fun of winter. Every day I will only leave a few homework for the students, let them study happily, make them develop in an all-round way, and make them have a good score in Chinese, mathematics, science, English, music and sports. In class, I will give them lectures in funny language, and then tell them those problems vividly, so that they can learn in happiness. Near the end of the term, I will tell them about the problems that may appear in the exam, so that they can do well in the exam. My student union is a group of smart people. I believe they will do well in the exam. After the exam, I will take them to see Longmen and play in the water park, so that they can have a happy holiday, I must be a teacher when I grow up. For this reason, I have been working hard, because I firmly believe that as long as I work hard, I will succeed. Thank you! 4.有关梦想的英语演讲稿大全 Dear leaders, teachers and students hello everyone! A flower opens so happily, but people will only notice its beauty when it blooms, but they can"t know its hard work for its dream. Before a bud opens, it always looks forward to the opening of that day; Before a person realizes his dream, he always fantasizes about everything in the future. The heart of all things in the world will always have a beautiful dream. This dream is holy and noble. It is the support and driving force for a person to move forward bravely. Dream is a yearning. It"s not easy for us to pursue the river if we don"t have a share of it, but it"s not easy for us to go against the reality, Although we may not achieve the desired goal, we have enjoyed this process. Despite how bitter it is and how tired it is, we will all find our original true and most beautiful self in this process. Dream is a persistence. But persistence is a kind of responsibility. In childhood, we often use childish words to say "I want to be a scientist when I grow up" and "I want to be a painter in the future". However, have you persisted in these childhood dreams? Do you dislike the promises you made at that time in your pursuit of success? Therefore, once you have established your future dream, don"t take into account the final outcome, and bravely break out a blueprint. Even if you fail, don"t forget your oath; Even if you succeed, you should keep it around your ears all the time. Dream is a struggle. In the struggle, it reveals a tenacity and flexibility. For the pursuit of dreams, we can"t stand still, but we can"t put all our eggs in one basket, because fighting with dreams is not simple. Recall how many times we prayed to God, but God should not control your destiny. The classic saying "fate can only be controlled by yourself" has educated many people and made them full of confidence! "The Xiongguan pass is really like iron. Now I"m going to cross from the beginning." It is the vision for the future and the courage to overcome difficulties. "There will be times when the wind and waves break through, and the clouds and sails are hanging straight to the sea." It is the expectation of life and the courage to never admit defeat. Then please let us plant a seed on our way to pursue our dreams in the future and wait for flowers to bloom in our dreams! 5.有关梦想的英语演讲稿大全 hello everyone! My name is XXX. I come from Baoding City, Hebei Province. At our age, everyone will have their own dream. It is like a lighthouse in the ocean, guiding the direction of our efforts and marking the goal of our struggle! My dream is to be an astronomer when I grow up. When I was very young, every time I looked up at the vast starry sky, my heart would be full of curiosity. Curiosity stimulated interest and interest gave birth to dreams. Therefore, I began to read various astronomical books. Among them, my favorite books are 100000 whys in space and the universe of exploration and discovery. From them, I learned the origin of the universe and the mystery of black holes, The relationship between galaxies and their operation have provided great help for my exploration of space. I roam in the endless space, from shallow to deep, and enjoy it. With these books, I grow up day by day. With the accumulation of knowledge, my dream is becoming clearer and clearer! The launch of Chang"e-2 is exciting. Every picture it sends back affects my heartstrings! Next year, China will launch spacecraft to explore Mars. Also next year, China will have its own space station. The increasingly powerful motherland and the rapid development of Aerospace Science and technology have strengthened my faith. In the future, I will build better spaceships and open up an air garden on the moon. The solid water there will be used by us to solve the shortage of water resources on the earth; I want to build a giant space station and build a space vegetable base on it to produce delicious space vegetables so that people on earth can also taste the sweetness from space; I want to refine solid and durable steel on the space shuttle to reduce carbon dioxide pollution; I also want to make a lightning collector. When there is a thunderstorm, it can automatically collect lightning and convert it into ultra-high magnetic sound waves, which can be used to treat people"s diseases and fill the world with health! In the future, I have many things to do. Today, we grow up healthily in the embrace of the motherland. Tomorrow, we will shoulder the burden of building the motherland. For the beauty of tomorrow and the rising China, I must study hard, work hard and put my dream into the blue sky as soon as possible! Thank you!2023-07-20 05:39:141
