  栏目介绍:搞笑英语轻松学通过不同的搞笑生活片段来学习日常口语,领域涉及生活的各个方面,让我们边看视频边学英语。正宗地道的口语,假一罚十。美剧电影真人秀都看过了之后还能看什么学口语呢?当然是看这些双语视频啦!又好玩,又原汁原味,又顺便学一两句地道英语,多痛快!快来看看吧!201604/434603

  栏目简介:《英语视频之Top10》是英语视频听力下的子栏目,栏目包含中英字幕,而且能够了解世界上10大新奇或者有意思的事物,比如奇葩犯罪记录、科学骗局、邪恶老师等,通过简单有趣的讲述,能够提高学习英语的兴趣,积累一些英语知识,是比较生动的英语学习材料。201601/416290The astronauts footprints stand preserved to this day.宇航员的足迹一直保存至今A testament to the beginning of what I think初步验了我所认为的could be the next chapter in the story of the cosmos.宇宙故事中的下一章:The sp of life to other part of the universe生命传播至宇宙其他地方As the universe gets older, we will have to get wiser.随着宇宙的成长,我们也要变得更加智慧I think we will have to go much further than the moon.我想我们应该探索比月球更远的地方At the very least to Mars.起码也应该探索火星The red planet is likely这一红色星球很可能to play an important part in our evolution.在我们的进化过程中扮演着重要角色and maybe even in the story of the cosmos.甚至在宇宙发展历程中也是Its the second and possibly the most important steppingstone它将是人类星际旅行的第二个on humanitys journey to the stars.很可能也是最重要的踏板Robot missions to Mars have revealed机器人的火星探测任务展示了a spectacularly beautiful yet dangerous and desolate place.一幅美丽而危险荒凉的壮观景象I imagine that being a human pioneer here would be an exciting business.我想,人类拓荒者抵达这里一定很令人兴奋For a start, its cold.首先,这里很寒冷Its 50 million miles further from the sun than the Earth到太阳的距离比地球远五千万英里and so it receives half as much warmth因此只接收到一半的热量and the temperatures fluctuate wildly.而且温度波动很大From 80 degrees to minus 200 in a matter of minutes.数分钟内从80度降到零下200度If the cold doesnt get you,如果寒冷的环境不能征你the low gravity will.那么低重力一定能办到Mars is just half the size of the Earth火星只有地球的一半大小and has just 38% of its gravity.而且重力只有地球的38%Overtime,explorerss bones would weaken久而久之,探索者的骨头将变脆 and their muscles would waste away.肌肉也将变得虚弱Spent long enough on Mars,在火星上呆久了and you could find yourself too weak to safely return to Earth.你会发现自己太过虚弱而无法安全回到地球The low gravity also means Mars struggles to hold on to an atmosphere.低重力同时意味着火星很难形成大气Here there is nothing more than a thin wisp of carbon dioxide这里除了稀薄的二氧化碳以外,什么也没有at just one-hundredth the pressure of our air.气压也只有我们气压的百分之一201510/404198

  The sun is around 4.5 billion years old.And just like you and I,its aging,In just over a billion years,the sun will expand it so much that the heat will begin to melt the earths surface,So,is there any way as earth things can avoid this detrimental event?Can we save ourselves from the suns ultimate death?太阳已有大约45亿岁了。正如你我一样,它也在衰老。在10亿年后 它将变得巨大 它带来的热量会融化地球表面。地球生物怎么才能躲过这次致命的打击?在太阳消亡时我们能否自保?Sure,none of us would be here,assuming we dont find the secret to everlasting life.but at the billion year mark,the sun will have used up the hydrogen fuel in its core,forcing it to burn at its surface.The increase radiation will boil away all of the water on earth,creating an international desert.当然 如果没发现长生不老的秘诀 我们活不到那时候。但十亿年后 太阳将会耗尽其内核所有的氢燃料,迫使其在表面燃烧。不断增强的辐射会蒸发干地球上所有的水分,造出洲际沙漠。Flash foward about 5 billion years,and the swelling sun will bigin literally melting mountains with most,if not all life on earth,now extinct.Around 7.5 billion years,the expanding sun,now a red giant,will engulf the earth entirely,Sounds bleak,so can we avoid this hot mass?再向后50亿年,巨大的太阳开始将融化山脉,而地球上绝大多数生物早已灭绝。75亿年后 不断膨胀的太阳已成红巨星,并将完全吞噬地球。听起来很吓人 那我们能躲过这团热球吗?It turns out,our best bet lies something called gravity assist.a technique we have been using for years only to launch space craft through our solar system.Any time a space craft or satellite comes in close proximity to a planet,Cravity grabs hold.And if the spacecraft arrives at the perfect angle,its able to use some of the planet velocity to catapult it further into space.This extra energy comes from the planets own enery of motion around the sun.实际上,我们最有利的赌注在于引力助推。一种多年来 我们只用在向太阳系内发射航天器的技术。当飞行器或卫星靠近行星时,重力会抓住它。如果飞行器的角度刚好合适,它可以利用行星的速度将自身推到宇宙更远。多余的能量来自于行星绕太阳旋转时自身的动能。But as Newton famously said,To every action,theres an equal and opposite reaction.As the spacecraft uses the earths gravity to speed up and move towards the earth,the planet will ever so slighty slow down and move toward the spacecraft.Of course,the spacecrafts mass is so small comparatively that it gets launched incredibly far while the planet experience little change.但正如牛顿所言,每个作用力都存在与之大小相等 方向相反的反作用力。当飞行器利用地球引力加速 向地球靠近时,地球的速度会略有下降 并向飞行器靠近一点。当然 相比之下飞行器的质量太小 以至于卫星可被发射到极远处 而行星却丝毫未变。But,if we were to increase the spacecrafts size,or use an asteroid,we could potentially move the earths orbit away from the sun.This would take millions of years and involve large objects coming just close enough to not collide with earth.But,hey,were got a billions years ahead start.It may seem far fetched,but its aly happening.但是 如果能让飞行器变大 或者利用小行星,我们就可以让地球轨道远离太阳。这需要数百万年时间,并得让足够大的物体离地球够近 却不能撞到地球。但是 我们还有好几十亿年时间呢。看上去很遥远 但这已经在发生了。On Oct,9,2013,earth will be used up to gravity assist a spacecraft called Juno which is on its way to Jupiter,As Juno flies within 559 km of us,it will use earths gravity as the slingshot to boost its velocity by 7.3km/s.Meanwhile,earth will have been moved by a fraction.Juno will later arrive at Jupiter in 2016,where it will study the interior of the planet and help to unveil many new spectacular mysteries of our solar system.在2013年10月9日,地球将为一颗名叫“Juno;的航天器做引力助推 后者正向木星前进。当Juno飞到距我们559千米处时,地球引力将是它的弹力 它将借此加速到7.3km/s。与此同时 地球仅被移动了一点点。Juno将在2016年抵达木星。在那里 它会研究行星的内部 并帮助我们揭秘关于太阳系的诸多精谜题。In order to move the earth within our billion years time line,we would need approximately one encounter every 6000 years,using an object with a mass of approximately 10^19 kilograms.Thats 0000,0000,0000,0000,000.Some are around the size of 100 kilometer wide asteroids,In between passes,the asteroid would slingshot around the sun,fly up to Jupiter and be gravity assisted back to the earth.Like one long version of catch between planets.为了在这十亿年间移动地球,我们大约得每6000年一次,用一个质量大约为10^19千克的物体。就是0000,0000,0000,0000,000.某些直径100千米的小行星差不多的东西。在中间穿过时小行星绕太阳绕太阳加速,飞到火星之后又被引力助推回地球。正如长距版的星际抛球。Over millions of years,this would move the earth to a comfortable 225 million km orbit out from the sun.While it is feasible,even with todays technology,it doesnt come without risks.For one,we may lose the moon,which could ultimately create some extreme weather patterns.Not to mention,the earths spin may increase,making days only hours long,The surrounding planets like our new neighbors,Mars,would likely have their own orbits disstabilized.几百万年后,地球将因此而移动到安全距离,距太阳 2.25亿公里的轨道。而即使计划可行,凭借今天的科技,这种方式仍有风险。其一,我们会失去月亮。这终将导致某些极端天气模式。更不用说地球自转的速度也将加快 每天都只有几小时。我们周围的新邻居 如火星,他们的轨道会变的不稳定。You know,the asteroid could come plummeting into earth by accident.But perhaps these other risks we need to take to give our decedents,the planet,and all life on it,a few extra billions of years.你知道,小行星也会偶然间砸向地球表面。不过 我们可能得把这些风险留给我们的子孙了一颗行星其上所有的生命,还有几十亿年。201502/361124栏目简介:;Shanghai Live; focuses on big events in the city and major issues around the world, and presents them in a practical and audience-friendly manner to meet the ever-evolving needs of Shanghais English-speaking viewers,both local and expatriate.《直播上海英语电台》集中报道城市大事件以及全球热点话题,并以观众喜闻乐见的方式呈现给大家,从而满足上海本地以及上海海外人士的英语需求。201511/411140

  A suicide bombing has killed at least 65 people, mostly women and children,in the Pakistani city of Lahore.在巴基斯坦拉合尔市,一自杀性爆炸事件造成至少65人死亡,大部分是妇女和儿童。Local authorities said at least 280 more people have been injured and that they fear the death toll is likely to rise.地方当局表示,至少有280人受伤,他们担心死亡人数可能继续上升。The Taliban has claimed responsibility for the attack and said “Christians were the target.”塔利班宣称对这一袭击负责,并称“基督教徒是袭击的目标。”The explosion appears to have happened in the parking area at Gulshan-e-Iqbal Park – a few metres from children’s swings.爆炸似乎发生在高尔杉伊克巴尔公园的停车,离儿童秋千几米远。The park had been particularly busy on Sunday due to the Easter holiday weekend.周日这个公园人特别多,因为复活节周末假期。Lahore is the capital of Punjab,Pakistan’s wealthiest province and the political power base of Prime Minister Nawaz Sharif. 拉合尔是旁遮普的首都,是巴基斯坦最富裕的省以及总理纳瓦兹·谢里夫政治权力基础。译文属。 /201603/434462。

  

  Mars is also bathed in harmful radiation from the sun,火星还沐浴在太阳的有害辐射中even though its further away,即使它离太阳更远unlike Earth it has no与地球不同的是,它没有磁场magnetic field and no ozone layer to protect it.也没有臭氧层的保护Early explorers would早期探索者们have to be careful to minimize their exposure必须小心让自己的暴露面积减到最小and perhaps they would have to live underground.或许他们还要居住在地下But one day, I think it will be possible但我认为,未来某天to drastically alter conditions on Mars,我们很可能完全改变火星的生存条件perhaps using space-bourne mirrors to supply warmth and power.比如利用空间反射镜供给热能与动能With perfectly foreseeable technology,在势必问世的更高科技出现后much more could become possible.更大的转变也将成为可能If we could erect giant domes made of glass and plastic若我们能够建造一个巨大的玻璃塑料拱顶to block out the radiation,来阻挡辐射inside them we could enrich the atmosphere.在拱顶之内,我们还能充实稀薄的大气500 years from now which really is a very short time indeed,我相信,在未来短短500年之内I think Mars will have its own language,火星人就会形成自己的语言its own currency, its own cuisine.货币,甚至烹饪之道Although Ill bet you will still be able to get a hamburger somewhere.不过我肯定你在那里仍旧能吃到汉堡包But its clear as the universe continues to age,但随着宇宙的不断变老even advances like these即使是这样的进展will not be enough to guarantee humanitys existence for a very long time.也无法保人类能够永久地繁衍生息Look further into the future and ultimately our solar system在更远的未来,我们的太阳系最终will follow the same path as countless billions of solar systems before it将与之前无数其他太阳系一样and cease to exist.不复存在Right now the sun is in the middle of its life cycle.现在的太阳正值壮年During this phase, it is getting gradually hotter这一阶段,它将以每十亿年6%的速度and brighter all the time by about 6% every billion years.逐渐地变热,变亮In about five billion years,在约五十亿年后the suns temperature will have grown to nearly 200 billion degrees.太阳的温度将增至近两千亿度At this point这时the Earth will be an unrecognizable ball of molten rock.地球将成为一颗难以辨认的熔岩球All life having long since perished.地球上的生命也早已不复存在This is our planets unavoidable destiny.这是我们这个星球难逃的命运But thats not all the sun has in store.但太阳将要带来的灾难远非如此201510/404721
