I also express my condolences to the relatives of the victims. We asked the concerned authorities to investigate into the causes of the dramatic incident and come out with the results of the investigations as soon as possible,” said King Salman bin Abdulaziz.“对今日米纳发生的踩踏事故我表示慰问。我还要向遇难者家属表示慰问。我们要求有关当局调查这起事件的原因,并尽快得出调查结果。”国王沙尔曼说道。The Saudi Health Minister said pilgrims failing to follow instructions had been the main cause of the tragedy.沙特卫生部长说,朝圣者未能按照指示行事是造成悲剧的主要原因。Security at the Hajj is a politically sensitive issue for Saudi Arabia, the guardians of the Islamic world’s most sacred sites.朝觐安全是沙特阿拉伯的政治敏感问题,伊斯兰世界最神圣遗址的守护者。译文属。 /201509/400979Now let#39;s see what happens when Dr. Dolhun adds the gummy bear下面来看Dolhun士加入橡皮糖熊会怎样Alright, so let#39;s just break down what just happened好 我来讲解一下发生了什么The sugar from the gummy bear橡皮糖熊中的糖and oxygen react to produce carbon dioxide and water同氧气反应 生成二氧化碳和水releasing a lot of energy as heat and light以热和光的形式释放出大量能量This is what that looks like情况是这样的And I#39;m going to draw sucrose or sugar in a red我用红色来画蔗糖 这是糖because that#39;s from the gummy bear来自于橡皮糖熊This reaction is probably familiar to you这个反应你们可能很熟悉It#39;s a combustion reaction这是一个燃烧反应which has been a fuel reacts with oxygen to produce carbon dioxide and water一种燃料同氧气反应 生成二氧化碳和水and at the same time releasing a bunch of energy同时释放出大量能量So why is so much energy released and where does it come from?为什么释放出这么多能量 能量来自何方To show you, I#39;m going to draw the structures为了说明这一点 我将画出结构图Now if you#39;re unfamiliar with organic chemistry notation给不熟悉有机化学表示法的同学解释下each of the lines between the elements that I#39;m going to draw我要画的每一条线represents a covalent bond都表示一条共价键which is the sharing of two electrons between two atoms也就是两原子间共用的两个电子So let me draw those我来画一下So here are the reactants这里是反应物and here are the products这里是产物Now by looking at the number of bonds and the type of bonds so我们可以观察键的数量和键的类型a carbon bonded to an oxygen碳同氧之间的键or carbon bonded to a carbon或碳同碳之间的键and a single bond versus a double bond还有单键同双键之间的区别you can calculate the energy difference由此可以计算出between the left side of the reaction, the reactants左侧反应物和右侧产物之间的能量差异and the right side or the products左侧反应物和右侧产物之间的能量差异Now all combustion reactions所有燃烧反应have more energy stored in the reactants than the products在反应物中储存的能量都大于产物So as the reaction progresses所以随着反应进行this energy has to go somewhere and it#39;s released as heat and light这些能量需要释放 于是就会生成热和光Now the amount of energy released from this explosion这个爆发中释放出来的能量is exactly the same as the amount of energy that would be released在量上同人体内消化这个橡皮糖熊时完全一样in my body when I eat this gummy bear在量上同人体内消化这个橡皮糖熊时完全一样The difference is that proteins in my body are set up in pathways差异在于 人体内的蛋白质在代谢途径中有很好的设计that extract the energy in small manageable bundles能够以可控方式逐步少量提取能量So I power my everyday activities like dancing and running这样我就能为日常活动 如跳舞 跑步 提供能量but I don#39;t explode但我不会爆掉Evolution has trained biological systems进化让生物系统组织得很好to efficiently extract energy from our environment由此能够有效提取环境中的能量Alright, that#39;s it for me today.

Your Wishes Delivered: Driver for a Day小卡森的快递梦I made deliveries to Carson probably two or three times a week. When I first started off, he wouldn#39;t even come out of the house.

He#39;s just intrigued by it.我大概一星期送货给 Carson 二或三次。我刚开始时,他甚至不会从屋子出来。他就只会从窗户内看着卡车。那有片大玻璃窗。他只要是卡车都爱,但因为某种原因,UPS 的卡车真的很吸引他。他就是被它给迷住了。Who is that guy?那是谁啊?Mr. Ernie and me.Erine 先生和我。Yeah, it#39;s pretty neat to see him all the time with his UPS uniform on.
