这哨子代价太高
(After Benjamin Franklin)
主讲:张光和
Benjamin Franklin was a statesman and diplomat
for the newly formed United States, as well as a prolific author and inventor. Franklin helped draft, and then signed, the Declaration of Independence in 1776, and he was a delegate to the Constitutional Convention in 1787. As a civic leader, he initiated a number of new programs in Philadelphia, including a fire company, fire insurance, a library, and a university.
I had given four times as much as the whistle was worth. They put me in mind of what good things I might have bought with the rest of the money,and laughed at me so much for foolishness. So I cried. Thinking about the matter gave me more shame than the whistle gave me pleasure.

Chemical reactions of jute are much like those of other cellulosic fibers. Resistance to alkalis and dilute acids is good. Concentrated acids do cause fiber breakdown. Sunlight does not damage jute. 黄麻遇化学制剂的（酸碱）反应就像其他的纤维素纤维 一样。具有好的耐碱和耐弱酸性。强酸会使纤维素分解。 光照对黄麻纤维没有破坏作用。
Jute is obtained from the stem of the plant. The major growing areas are Bangladesh,India,and Thailand. In fabric it isfrequently called burlap or hessian. 黄麻是从植物的茎中获得，它的主要生长地区是孟加拉 国，印度和泰国。从织物构造方面，它被频繁的成为粗 麻布或打包麻布。
Care of jute is similar to that of flax except for the fact that colored jute may require dry cleaning. Jute is widely used in developing countries and others where labor is available at relatively low cost. It is a labor-intensive commodity and requires a high proportion of labor in processing. 黄麻的护理类似于亚麻除了这一事实有色黄麻可能需要 干洗。黄麻被广泛的用于发展中国家和其他劳动成本相 对较低的地方，它是一个劳动密集的商品，并且在处理 中劳动力需要的比例很高。

Lesson Eight Science Has Spoiled My Supper科学毁了我的晚餐I am a fan for Science. My education is scientific and I have, in one field, contributed a monograph to a scientific journal.我是个科学迷。
我是学科学的，曾为一份科学刊物写过某个领域的一篇专题文章。
Science, to my mind, is applied honesty, the one reliable means we have to find out truth.在我看来，科学需运用诚实，是我们发现真理的唯一可靠的手段。
That is why, when error is committed in the name of science, I feel the way a man would if his favorite uncle had taken to drink.因此在以科学的名义做错事时，我的感觉就像一个人最喜欢的叔叔染上酒瘾后的心情一样。
Take cheese, for instance.Here and there, in big cities, small stores and delicatessens specialize in cheese.以奶酪为例。
在大城市到处都有一些小店和熟食店专营奶酪。
At such places, one can buy at least some of the first –rate cheeses that we used to eat在这些地方，至少还能买到过去吃过的一些最好的奶酪---such as those we had with pie and macaroni (通心粉).比如我们在吃馅饼和通心粉时吃的奶酪。
lesson eight animal development
The first contact of the sperm head with the egg‘s jelly coat triggers the acrosome reaction, in which enzymes are released to digest a hole through the egg’s protective layers, and the plasma membrane of the sperm is brought into position to bind to the ovum‘s surface. 当精子和卵子的胶状膜发生接触时，触发了顶 体反应。释放多种酶而将卵保护膜消化出一个 洞。精子的原生质膜与卵子的表面连接起来。
Ova, which are produced during oogenesis, are generated in gonial cells (oogonia) of the female's ovaries. Oocytes then enter a stage of arrest in early meiosis. 在卵子发生过程中，由卵巢中的性母细胞 产生。卵母细胞进入减数分裂的抑制阶段。

Lesson Eight How to Reduce Stress, Anxiety and Worry
Lesson Eight How to Reduce Stress, Anxiety and Worry参考译文如何减轻压力、焦虑和烦恼[1] 说起来可能令人惊讶，但生活中就是需要压力。
权威的压力问题专家说，生活没有压力便会单调乏味，缺少刺激。
压力会给生活增添色彩、挑战和机遇。
然而，过多的压力会严重地影响人的身心健康。
在当今充满压力的世界中，一个主要的挑战就是要使生活中的压力为人服务而非与人为难。
[2] 在当今繁忙、快节奏的世界里，压力总是伴随着我们。
精神或情感活动以及体力活动都可产生压力。
太多的情感压力导致身体生病，诸如高血压、溃疡病、哮喘、过敏性结肠炎、头痛，甚或心脏病。
而另一方面，由工作或运动引起的体力上的压力却很少导致诸如此类的疾病。
实际上，体育锻炼能帮助人放松，并处理精神或情感上的压力问题。
[3] 医学博士汉斯·赛利是这一领域的公认的专家，他把压力解释为一种“对身体某一需求的非特异性反应”。
减轻压力的关键是要明白我们的躯体如何对那些需求做出反应。
如果压力持续时间较长或特别是人沮丧，那会变得非常有害---引起痛苦或“严重的紧张感”。
如果能识别这种痛苦的初期征兆并对其采取措施，会使人的生活质量得到显著的改观。
[4] 为了从积极的方面利用压力，防止其变为痛苦，人们应该知道自己对造成压力的事情由什么样的反应。
人体对压力的反应是经过一定阶段的：（1）惊恐，（2）抵制，（3）疲乏。
肌肉紧张，血压和心律升高，肾上腺素及其他由血压引起的、增高戒备水平的激素便释放出来。
如果引起压力的情况继续下去的话，人体便需要时间来修复了。
如果那样的话，最后可能出现于压力有关的疾病，诸如周期性偏头痛、高血压、后背痛或失眠。
这就是为什么当压力出现时识别它并积极的对付它是重要的。
[5] 虽说人活着不可能完全没有压力和烦恼，但避免某些烦恼及在回避不了烦恼时尽量减少它的影响确实可能的。
美国社会保健及福利部建议用下列方法来克服压力。
