作者:解腾跃英语中存在着一类是可以独立使用的符号——单词(如moon,eat等),另一类是不行独立使用的符号——词根(如lun,vis等),正是这种“一个意义,二种符号”的现象形成了数以万计的英语词汇。英语词根(root)是有限的,可是它们的能量很大,它们“向导”和“统辖”了英语中约80%的词汇,这是我们快速、科学、有效影象大量英语词汇基础。今天我们来看两个词根,kilo-和micro-。KILOKILO是希腊词语chilioi的法语版,意思是“thousand”。

法国大革命后,接纳了强制性的新单元——公制,一种国际的怀抱衡制度。继而公制逐渐被全世界多个国家定为官方制度。1858年,公制传入中国。

在英语中,kilo-主要在公制单元中泛起,如kilometer。在盘算机发现之前,大家最熟悉的单元莫过于kilowatt和kilowatt-hour。kilowatt的意思是“1000瓦特”,kilowatt-hour的意思是“千瓦时”——一千瓦在一小时内消耗的能量。

同样,当今人们在表现人为时,常用3k、8k、1.1k来表现,后面的k即kilo的意思,表现“千”。kilometer 英[?k?l???mi?t?],美[k??lɑm?t?r]A unit of length equal to 1,000 meters. 一千米的长度,千米A kilometer is equal to about 62/100 of a mile, and a mile is equal to about 1.61 kilometers.Footraces are usually measured in meters or kilometers, just like the Olympic races. Runners ofter abbreviate kilometer to K:“ a 5K race” or “a 10K run”, and so on.length:长度 equal to: 即是 mile:英里footrace:赛跑,竞走 measure:丈量abbreviate:缩短,简称kilogram 英&美[?k?l?ɡr?m]A unit of weight equal to 1,000 grams. 一千克的重量,千克The original concept of the kilogram, as the mass of a cubic decimeter of water was adopted as the base unit of mass by the new revolutionary government of France in 1793.In 1889 a new international standard for the kilogram, a metal bar made of platinum iridium, was agreed to.weight:重量 original:原始的,最初的 concept:观点mass:质量 cubic:立方的 decimeter:分米,共寸adopt:接纳,收养 standard:尺度 platinum iridium:铂铱(合金)kilohertz 英&美[k?l?h???ts]A unit of frequency equal to 1,000 cycles per second. 一千赫兹(频率的单元)Hertz honor the great German physicist Henrich Hertz, the first person to broadcast and receive radio waves.If your favourite AM radio station has a frequency of 680 kilohertz(kHz), that means the station’s transmitter is oscillating(vibrating) at a rate of 680,000 cycles per second.A related term is megahertz(MHz), meaning “millions of cycles per second.”frequency:频率 cycle:循环 honor:纪念broadcast:广播 receive:吸收 radio wave:无线电波radio station:广播电台 transmitter:发射器 oscillate:振荡,摇摆,颠簸vibrate:振动 rate:速度,比率 megahertz:兆赫,百万赫兹让我们来随着下面的导图回忆和发散一下,:MICROMICRO泉源于希腊词汇mikros,意思是“small”,小的,微观的。

A microscope lets the eye see microscopic objects. 显微镜可以让眼睛看到微观事物。在老报刊、报纸行业,人们还保留着只有原始巨细的1/400比例的microfilm(微缩胶卷)。在现实生活中,micro-是一个很是常见、易于明白的前缀,如microbus(小型公共汽车)、microquake(微型地震)、Microsoft(微软公司)。

在科学方面,科学家常用micro-表现“millionth”,“百万分之一”。因此,microsecond(微秒,百万分之一秒)是一秒的百万分之一,micrometer是一米的百万分之一。microbe英[?ma?kr??b],美[?ma?kro?b]An organism of microscopic or less than microscopic size. 微生物(显微镜下可见或小于显微镜可见巨细的有机体)A hint of the Greek word bios, meaning “life”, can be seen in microbe.Microbes, or microorganisms, include bacteria, protozoa, fungi, algae, amoebas and slime molds.Many people think of microbes as simply the causes of disease, but every human is actually the host of billions of microbes, and most of them are essential to our life.hint:表示,迹象 bacteria:细菌 protozoa:原生动物 fungi:真菌algae:藻 amoebas:变形虫 slime molds:黏菌 cause:原因host:宿主 disease:疾病 billions of:数以亿计 essential:必须品microbiologist 英[?ma?kr??ba???l?d??st],美[?ma?kro?ba??ɑ?l?d??st]A scientist who studies extremely small forms of life, such as bacteria and viruses. 微生物学家(研究极其微小的生命形式,如细菌和病毒)Since microorganisms are involved in almost every aspect of life on earth, microbiologists work across a broad range of subject areas.A marine microbiologist studies the roles of microbial communities in the sea.A soil microbiologist might focus on the use and spread of nitrogen.Some are studying whether microbes could adapt to life on the surface of Mars.extremely:极其的 involve:包罗,牵涉 work across:跨越 a broad range of:广泛的marine:海,海上,水师 roles:角色 microbial community:微生物群落 soil:土壤focus on:专注于 nitrogen:氮,氮气 adapt to:适应 surface:外貌microbrew 英[?ma?kr???bru?],美[?ma?krou?bru?]A beer made by a brewery that makes beer in small amounts. 微酿,精酿(小数量酿制的啤酒)Microbrews are usually beers or ales made with special malts and hops.Many microbreweries double as bar/restaurants, call brewpubs, where the gleaming vats may be visible behind a glass partition.But not everyone is willing to pay extra for a beer, and lots of people are simply used to the blander taster of the best-selling beers, so by 2008 microbrews still only accounted for about 4% of all beer sold in the U.S.amount:数量,数目 malt:麦芽 hop:啤酒花 microbrewery:小型酒厂 brewpub:自酿旅店gleaming:闪耀的 vat:酒桶 visible:可见的 partition:隔绝 extra:分外,多blander:混淆的 be used to:习惯于 taster:样品,酒 best-selling:最脱销的 account for:(数量、比例上)占让我们来随着下面的导图回忆和发散一下,:今天的词根解说就为大家先容到这里,划分学习了kilo-(千)和micro-(微小的),大家在学习之后,再次在词汇中见到它们,不妨凭据组合的意思做一个推测,再去凭据真实意思做一下判断。

随着重复使用,一定会有更好的明白进步。好奇下次给大家带来什么故事和词根吗?敬请期待。
