Take two nails and scrape them together vigorously. Now touch the place you were scraping. Itrsquo;s hot! Let them cool and try it again. Itrsquo;s hot again! You could do this all day and the nails would never stop growing hot. If heat were a liquid, there would have to be an infinite amount of it even in a tiny nail. Whatrsquo;s the better answer? Heat is a measure of kinetic energy. Kinetic energy means the amount of motion the molecules in the nail have, or how much they jostle against each other. The hot spoon heats your hand not because something invisible is being poured in, but because the fast-jostling molecules of the spoon hit the molecules in your hand and start them jostling too. In the case of the nails, all thatrsquo;s needed to produce more heat is to start jostling those molecules again after theyrsquo;ve calmed down. You wonrsquo;t ever run out of heat.以两个钉子和他们一起大力刮。现在触摸的地方,你被刮。它的热!让他们冷静,并再次尝试。它的热了!您可以这样做,整天和指甲永远不会停止增长热点。如果热的液体,它是一个无限量,即使在一个微小的指甲。什么更好的吗?热是一种动能的措施。动能手段的运动量在指甲的分子,或有多少,他们对彼此争抢。热勺加热你的手不会因为看不见的东西正在浇筑,但由于勺子快速冲撞分子的分子打在你的手,开始他们过于拥挤。在指甲的情况下,所有的需要产生更多的热量是开始再次冲撞这些分子后,他们已经平静下来。你永远不会用完的热量。201201/169529

A male polar bear is searching for a mate. Willing females are few and far between. And the sea ice some of which he travels will soon melt and vanished. Hes running out of time to find the mate in this frost frozen desert.一只雄性北极熊正在寻找一位伴侣。无奈美女们少之又少。海冰的融化导致旅程将很快到达终点。他走了很长时间才能在这个冰冻荒漠找到伴侣。Ten miles ahead, a single female without companies is exactly what the male is seeking. He seems to relish her scent even though shes miles away. This is an exciting prospect. Shes clearly giving off the right signal. He locks onto her tracks eager not to lose her trail. Its easier to track in a compacting snow of her footprints. This pursuits can last for days. The female eventually comes into field. Search is finally over. Could the female only half his wait, this must be a neracking encounter. The male could kill her if he chooses. But he has other intentions. And she is y and willing. She leads him to higher ground. It seems that courting polar bear prefer privacy, often leaving the sea ice and heading for the hills to avoid the prime eye of the rival males who might disturb them.前面十英里,确实有一位没有男性追求的单身女性。虽然相隔数里,但他似乎很欣赏她的气味。这是一个令人兴奋的预兆。很明显她发出了合适的信号,他跟上她的行踪渴望不失去她的踪迹,这就更容易追踪压实的雪上她的脚印了。这场恋爱追逐能持续数天之久。她最终进入地盘,而追逐终于要结束了。似乎这位女性好像只有5成的几率是在等他,这肯定是一个蹩脚的相遇。如果选择,男性可以杀死她,但是他有其他的意图。她已经准备就绪并带他到更高的地方。看来求爱的北极熊更喜欢隐私,经常离开海冰来到山里来避免主要竞争对手的打扰。注:听力文本来源于普特 201201/167131

Europes biggest defense contractor and its biggest aerospace firm are in advance talks to merge. BAE Systems and EADS reveal they have aly agreed to most of the details of the combining group but theyve yet to pull the trigger.欧洲最大的防务承包商及最大的航空公司的合并谈判已进入高级阶段。英国宇航系统公司(BAE Systems)和空客母公司欧洲宇航防务集团(EADS)透露双方已就两大公司的合并细节基本达成一致,不过现在还未扣动扳机。If the mega merge went ahead, the two remain separately listed companies but with a new parent company above them with the ability to massively cut costs at a time when defense budgets are under strain. The two firms aly work closely on projects like the Airbus A380 super-jumbo project and the Eurofighter Typhoon attack jet.如果此次大型合并得以成功施行,这两家公司仍将保留其独立上市公司身份,但是两家公司将同属一新母公司旗下,该母公司将有能力在欧美国防预算缩减局面下,大幅度降低成本。两家公司目前已在一些项目上展开亲密合作,如空客巨无霸A380大型机项目及欧洲战机台风战斗机。A merger will need approval of both boards but also regulators around Europe, and importantly, regulators in the ed States where BAE Systems has steadily become one of the biggest defence contractors for the Pentagon. Some US aerospace firms may also have something to say about a massive new kit on the block. 这样一个商业合并不仅要经双方董事会的同意,还要有欧洲境内的相关监管机构的许可,重要的是,需要美国相关监管机构的同意, 因为BAE Systems已经成为五角大楼最大的固定国防业务承包商之一。一些美国航空公司可能也会对此次合并发表其意见。EADS has been trying to build up a bigger military presence in the US and rely less on its commercial aircraft site for growth.EADS一直努力想在美国打造一个更大的军用飞机制造分公司,以此减少对民用商务飞机业务增长的依赖。BAE Systems shares soared in the last 45 minutes of trading Wednesday before the announcement was made official.两大巨头合并的官方申明宣布之前的周三,当日交易时间结束的最后45分钟内,BAE Systems的股票暴涨。Jim Bowe, CNN, London.
