Why We're Fat1 So why is obesity happening? The obvious, clichéd-but-true answer is that we eat too much high-calorie food and don't burn it off with enough exercise. If only we had more willpower, the problem would go away. But it isn't that easy.为什么会有肥胖症?一个明显、老生常谈但又真实的答案就是我们吃太多高热量食物并且没有进行足够的运动消耗它。
要是我们的意志力更强大,这个问题便迎刃而解了。
但是,问题并不是那么简单。
2 When warned about the dangers of overeating, we get briefly spooked and try to do better. Then we're offered a plateful of pancakes smothered in maple syrup, our appetite overpowers our reason, and before we know it, we're at it again. Just why is appetite such a powerful driver of behavior, and, more important, how can we tame it? 当我们被警告说吃得太多的时候,一时总会被吓倒并努力做好一些。
然后一碟涂满槭糖浆的煎饼摆在面前,我们的食欲战胜了我们的理智,等到我们意识到它的时候,我们又重蹈覆辙了。
到底为什么食欲具有如此强大的推动力?更重要的是,我们怎么才能够控制它?3 Within the past few years, science has linked our ravenous appetites to genes and hormones. Among the hormones that fuel these urges are ghrelin and leptin, known as the "hunger hormones." Ghrelin is produced mostly by cells in the stomach lining. Its job is to make you feel hungry by affecting the hypothalamus, which governs metabolism. Ghrelin levels rise in dieters who lose weight and then try to keep it off. It's almost as if their bodies are trying to regain the lost fat. This is one reason why it's hard to lose weight and maintain the loss.近几年来,科学将我们迫不及待要吃的食欲跟基因和激素联系起来。

1 Hello. My name is Stephen Hawking. Physicist, cosmologist and something of a dreamer. Although I cannot move and I have to speak through a computer, in my mind I am free. Free to explore the universe and ask the big questions, such as: is time travel possible? Can we open a portal to the past or find a shortcut to the future? Can we ultimately use the laws of nature to become masters of time itself?大家好,我是斯蒂芬-霍金,是物理学家、宇宙学家及梦想家,尽管身体不能活动,只能通过电脑与大家交流,但从内心中我是自由的,自由地探索宇宙,思考以下重大问题:时间旅行是否可行?能否打开一个回到过去的通道,或找到通向未来的捷径?我们最终能否利用自然规律成为掌控时间的主人?2 To see how this might be possible, we need to look at time as physicists do - at the fourth dimension. It's not as hard as it sounds. Every attentive schoolchild knows that all physical objects, even me in my chair, exist in three dimensions. Everything has a width and a height and a length.为了让这一切从虚幻变成现实,我们应以物理学家的角度来重新审视时间——即第四维。

Unit 1 Genetically modified foods -- Feed the World?If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature.如果你想在某次晚宴上挑起一场激烈的争论,那就提出转基因食品的话题吧。
对许多人来说,高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。
特别是在有悠久的农业生产传统和主张环保的游说集团的国家里,转基因食品的主意似乎有悖自然。
In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle.事实上,转基因食品已经成为我们生活重要的一部分。

Unit 1 对F的赞美1今年将有好几万的十八岁青年毕业,他们都将被授予毫无意义的文凭。
这些文凭看上去跟颁发给比他们幸运的同班同学的文凭没什么两样。
只有当雇主发现这些毕业生是半文盲时,文凭的效力才会被质疑。
2最后,少数幸运者会进入教育维修车间——成人识字课程,我教的一门关于基础语法和写作的课程就属于这种性质。
在教育维修车间里,高中毕业生和高中辍学生将学习他们本该在学校就学好的技能,以获得同等学力毕业证书。
他们还将发现他们被我们的教育体系欺骗了。
3在我教课的过程中,我对我们的学校教育深有了解。
在每学期开始的时候,我会让我的学生写一下他们在学校的不快体验。
这种时候学生不会有任何写作障碍!“我希望当时有人能让我停止吸毒,让我学习。
”“我喜欢参加派对,似乎没人在意。
”“我是一个好孩子,不会制造任何麻烦,于是他们就让我考试通过,及时我阅读不好,也不会写作。
”很多诸如此类的抱怨。
4我基本是一个空想社会改良家,在教这门课之前我将孩子们的学习能力差归咎于毒品、离婚和其他妨碍注意力集中的东西,要想学习好就必须集中注意力。
但是,我每一次走进教室都会再度发现,一个老师在期望学生全神贯注之前,他必须先吸引学生的注意力,无论附近有什么分散注意力的东西。
要做到这点,有很多种办法,它们与教学风格有很大的关系。
然而,单靠风格无法起效,有另一个办法可以显示谁是在教室里掌握胜局的人。
这个办法就是亮出失败的王牌。
5我永远也忘不了一位老师亮出那张王牌以吸引我的一个孩子的注意。
我的小儿子是个世界级的万人迷,学习不怎么动脑筋却总能蒙混过关。
直到施蒂夫特夫人当了他的老师,这种局面才彻底改变了。
6当她教我儿子英语时,我儿子是一个高中高年级学生。
“他坐在后排和他的朋友说话。
”她告诉我。
“你为什么不把他换到前排来?”我恳求道。
我相信令他难堪的做法会让他安心学习。
施蒂夫特夫人从眼睛上方冷冷地看着我。
“我不会换高年级学生的座位。
”她说,“我会给他们不及格的成绩。

核电与核辐射1986年4月26日,切尔诺贝利核电站的一个反应堆发生爆炸,将相当于400颗广岛原子弹的放射性尘降物散布到整个北半球。
在此之前,科学家对辐射对植物和野生动物的影响几乎一无所知。
这场灾难创造了一个活生生的实验室,尤其是在这个被称为禁区的1100平方英里的区域。
1994年,德州理工大学生物学教授罗纳德·切瑟和罗伯特·贝克是首批获准完全进入该区域的美国科学家之一。
“我们抓了一群田鼠,它们看起来和野草一样健康。
我们对此非常着迷。
”贝克回忆说。
当Baker和Chesser对田鼠的DNA进行测序时,他们没有发现异常的突变率。
他们还注意到狼、猞猁和其他曾经稀有的物种在这片区域游荡,仿佛这里是原子野生动物保护区。
2003年由一组联合国机构建立的切尔诺贝利论坛发表了声明一份关于灾难20周年的报告证实了这一观点,称“环境条件对该地区的生物群落产生了积极影响”,将其转变为“一个独特的生物多样性保护区”。
五年前,贝克和切塞尔在这片区域搜寻田鼠。
Mousseau到切尔诺贝利去数鸟,发现了与之相矛盾的证据。
穆萨乌是南卡罗莱纳大学的生物学教授,他的合作者安德斯·佩普·穆勒现在是巴黎南方大学生态、系统学和进化实验室的研究主任。
他们发现该地区家燕的数量要少得多,而那些存活下来的家燕则遭受着寿命缩短、(雄性)生育能力下降、大脑变小、肿瘤、部分白化病(一种基因突变)以及白内障发病率更高的痛苦。
在过去13年发表的60多篇论文中,Mousseau和Moller指出,暴露在低水平辐射下对该区域的整个生物圈产生了负面影响,从微生物到哺乳动物,从昆虫到鸟类。
包括贝克在内的批评人士对穆萨和穆勒持批评态度。
贝克在2006年与切塞尔合著的《美国科学家》(American Scientist)文章中指出,该区域“实际上已成为一个保护区”,穆萨和穆勒的“令人难以置信的结论只得到了间接证据的支持”。
我们所知道的关于电离辐射对健康影响的几乎所有信息都来自于一项正在进行的对原子弹幸存者的研究,该研究被称为寿命研究,简称LSS。

Why We're Fat1 So why is obesity happening? The obvious, clichéd-but-true answer is that we eat too much high-calorie food and don't burn it off with enough exercise. If only we had more willpower, the problem would go away. But it isn't that easy.为什么会有肥胖症?一个明显、老生常谈但又真实的答案就是我们吃太多高热量食物并且没有进行足够的运动消耗它。
要是我们的意志力更强大,这个问题便迎刃而解了。
但是,问题并不是那么简单。
2 When warned about the dangers of overeating, we get briefly spooked and try to do better. Then we're offered a plateful of pancakes smothered in maple syrup, our appetite overpowers our reason, and before we know it, we're at it again. Just why is appetite such a powerful driver of behavior, and, more important, how can we tame it? 当我们被警告说吃得太多的时候,一时总会被吓倒并努力做好一些。
然后一碟涂满槭糖浆的煎饼摆在面前,我们的食欲战胜了我们的理智,等到我们意识到它的时候,我们又重蹈覆辙了。
到底为什么食欲具有如此强大的推动力?更重要的是,我们怎么才能够控制它?3 Within the past few years, science has linked our ravenous appetites to genes and hormones. Among the hormones that fuel these urges are ghrelin and leptin, known as the "hunger hormones." Ghrelin is produced mostly by cells in the stomach lining. Its job is to make you feel hungry by affecting the hypothalamus, which governs metabolism. Ghrelin levels rise in dieters who lose weight and then try to keep it off. It's almost as if their bodies are trying to regain the lost fat. This is one reason why it's hard to lose weight and maintain the loss.近几年来,科学将我们迫不及待要吃的食欲跟基因和激素联系起来。
激起这些强烈的欲望的激素有胃促生长素和消瘦素,也被称作“饥饿激素”。
胃促生长素主要由胃保护层的细胞产生。
它的职责是影响控制新陈代谢的下丘脑,让你感到饥饿。
当节食者减肥并且努力维持减肥效果,他的胃促生长素水平就会升高。
就像他们的身体要试图恢复失去的脂肪。
这是为什么很难减肥并维持减肥效果的原因之一。
4 Leptin turns your appetite off and is made by fat cells. Low leptin levels increase your appetite and signal your body to store more fat. High leptin levels relay the opposite signal. Many obese people have developed a resistance to the appetite-suppressing effects of leptin and never feel satisfied, no matter how much they eat. Basically, your body uses these hormones to help you stay at your weight and keep you from losing fat —which is another reason why dieting can be so difficult.消瘦素消除你的食欲,它来自脂肪细胞。
低消瘦素水平增加你的食欲并通知你的身体储存更多的脂肪。
高消瘦素水平传递相反的信号。
很多肥胖的人已经形成了一种对消瘦素抑制食欲效应的抵抗,不管他们吃多少也从不感到满足。
从根本上说,你的身体利用这些激素帮助你保持现在的体重,不让你的脂肪流走——这是节食如此之难的另外一个原因。
5 Lack of sleep promotes obesity by messing with these hunger hormones. If you skimp on sleep, ghrelin levels rise, making you hungry, and leptin levels dip, which signals a need for calories. During my internship, I was chronically sleep-deprived because I had to be at the hospital and stay up all night every third night. I gained a lot of weight that year; now I know why. Years later, after I gave birth to my son Alex, I put on a lot of pounds, too —twenty pounds left over from the pregnancy, and twenty pounds from being up all night with him. He had colic (fussiness) and never slept more than twenty minutes at a time the first six months of his life. My weight started coming off more easily when I got more sleep.睡眠缺失促进肥胖,因其干扰了这些饥饿激素。
如果你克扣了睡眠时间,胃促生长素水平升高,使你饥饿,并且消瘦素下降,标志着需求热量。
在实习期间我长期缺觉,因为每隔三个晚上我得通宵熬夜待在医院里。
那年我的体重增加了不少,现在我明白为什么了。
在那几年之后,我生了儿子亚力克斯后又增了好多磅——怀孕期间残留的二十磅,还有夜夜无眠陪着他的二十磅。
他有急性腹痛且在他生命中的头六个月从未试过连续睡二十分钟以上。
当我有了更多睡眠时间,我的体重开始更容易降下来。
6 Besides ghrelin and leptin, many other hormones play a role in appetite. Scientists have been looking for ways to control all these hunger hormones, but so far nothing usable has panned out.除了胃促生长素和消瘦素,很多其他的激素对食欲也有影响。
科学家一直在寻找控制这些饥饿激素的方法,但是目前还没有成果。
7 Hunger isn't the only reason people eat and eat and eat. Stress, depression, boredom, loneliness, and even joy all come into play. And some of us may just be inclined to gain weight while others are not, due to genetics. Scientists are unclear as to how much of a role genetics plays in how chubby you are, but estimates range from as low as 20 percent to as high as 90 percent. In studies of twins, researchers have found that siblings wind up with similar body weights, whether or not they are raised in different families, and that adopted children are much more likely to grow to the size of their natural parents than their adoptive ones. Scientists speculate that part of the reason so many of us are susceptible to layering on fat is due to the "thrifty gene." Supposedly, it's a gene passed down from our prehistoric ancestors who could eat a lot and build up reserves of fat to survive frequent famines. Genetically, this made sense when you didn't know if your next meal would be tomorrow or a week from now, but when your next meal is whenever you drive by a fast-food restaurant, that's a problem.饥饿不是人们不停地吃的唯一原因。
