Community service is an important component of education here at our university.

在我們大學這里，社區(qū)服務是教育的一個重要組成部分

We encourage all students to volunteer for at least one community activity before they graduate.

我們鼓勵所有的學生志愿參加至少一次社區(qū)活動在他們畢業(yè)前

A new community program called "One On One" helps elementary students who've fallen behind.

一個新的社區(qū)計劃，叫做“一對一”，幫助落后的小學生

You education majors might be especially interested in it because it offers the opportunity to do some teaching—that is, tutoring in math and English.

你們教育專業(yè)的可能對此尤其感興趣，因為它提供了教學的機會，也就是說，輔導數學和英語

You'd have to volunteer two hours a week for one semester. You can choose to help a child with math, English, or both.

你們必須在一學期內每周志愿服務兩個小時。你可以選擇幫助一個孩子的數學、英語或兩個都幫。

Half-hour lessons are fine, so you could do a half hour of each subject two days a week.

半個小時的課程就好，所以你可以每項做半個小時, 一周做兩天。

Professor Dodge will act as a mentor to the tutors---he'll be available to help you with lesson plans or to offer suggestions for activities.

Dodge教授會擔任家教們的輔導者，他將能夠幫你做授課計劃或者提供活動的建議

He has office hours every Tuesday and Thursday afternoon.

他每周二、四的下午有工作時間。

You can sign up for the program with him and begin the tutoring next week.

你可以在他那兒報名參加計劃，并且下周開始家教

I'm sure you'll enjoy this community service and you'll gain valuable experience at the same time.

我相信你將會享受這個社區(qū)服務，同時你將獲得有價值的經驗

It looks good on your resume, too, showing that you've had experience with children and that you care about your community.

這個也會在你的履歷上看起來很好，顯示你有孩子方面的經驗，同時你很關心你的社區(qū)。

If you'd like to sign up, or if you have any questions, stop by Professor Dodge's office this week.

I hope you've all finished reading the assigned chapter on insurance so that you're prepared for our discussion today.

我希望你們都已經讀完了保險上的指定章節(jié)，所以你們已經準備好了咱們今天的討論。

But, before we start, I'd like to mention a few things your text doesn't go into.

但是，在我們開始之前，我想提及一些你們課本上沒有探究的事

It's interesting to note that insurance has existed in some form for a very long time.

值得注意的是，保險已經以某種形式存在了很長一段時間

The earliest insurance policies were what we are called bottomry(use boats as mortgage) contracts.

最早的保險契約被我們稱作壓船借款合同

They provided shipping protection for merchants as far back as 3000 B.C.

他們早在公元前3000年就為商人提供了海運保護

In general, the contracts were often no more than verbal agreements.

一般來說，這些合同通常也不過是口頭協議

They granted loans to merchants with the understanding that if a particular shipment of goods was lost at sea, the loan didn't have to be repaid.

他們發(fā)放貸款給商人，帶著這樣的諒解：如果一船特定的貨物損失在海上，貸款不必償還。

Interest on the loans varied according to how risky it was to transport the goods.

貸款的利息的變化取決于運送貨物的風險程度

During periods of heavy piracy at sea, for example, the amount of interest and the cost of the policy went up considerably.

在海上盜賊嚴重的時期，舉例來說，利息的數量和保單的代價上升的相當之高。

So, you can see how insurance helped encourage international trade.

所以，你能看到保險是如何幫助并激勵國際貿易的

Even the most cautious merchants became willing to risk shipping their goods over long distances, not to mention in hazardous weather conditions when they had this kind of protection available.

即使最謹慎的商人也變得愿意冒險去長距離運送他們的貨物，更不用說在危險的天氣條件下當他們能得到這種保護了。

Generally speaking, the basic form of an insurance policy has been pretty much the same since the Middle Ages.

一般而言，保單的基本形式從中世紀以來基本上是一致的

There are four points that were salient then and remain paramount in all policies today.

那時，有四點是突出的，并且至今在所有保單中依然是最重要的。

These were outlined in chapter six and will serve as the basis for the rest of today's discussion.

這些被概述在第六章，并將作為今天討論剩余部分的基礎。

Can anyone tell me what one of those points might be?

有人能告訴我這幾點的其中之一可能是什么嗎?

Located at the NASA Research Center in Iowa is a 5,000-gallon vat of water, and inside the tank is an underwater treadmill designed by Dava Newman, an aerospace engineer.

在在愛荷華美國國家航空航天局研究中心有一大桶5000加侖的水，在水槽內有一個水下跑步機，由Dava Newman，一個航空工程師設計。

For four years Newman observed scuba divers as they simulated walking on the Moon and on Mars on her underwater moving belt.

四年來，Newman觀察了水肺潛水員們，他們在她的水下移動帶上模擬在月球和火星上行走。(四年來，當水肺潛水員們在她設計的水下移動帶上模擬月球和火星上行走時，Newman觀察了他們。)

She wanted to discover how the gravity of the Moon and of Mars would affect human movement.

她想要發(fā)現月球和火星的重力是如何影響人體運動的。

To do this, Newman attached weights to the divers and then lowered them into the tank and onto the treadmill.

為此，Newman附加了重量在潛水員身上并且把他們下放到水箱中的跑步機上。

These weights were carefully adjusted so that the divers could experience underwater the gravity of the Moon and of Mars as they walked on the treadmill.

這些重量是仔細校準過的，所以潛水員們能夠在水下體驗月球和火星的重力，當他們行走在跑步機上時。(所以當他們走在跑步機上時，潛水員們能夠在水下體驗月球和火星的重力)

Newman concluded that walking on Mars will probably be easier than walking on the Moon.

Newman推斷行走在火星上可能會比行走在月球上容易些

The Moon has less gravity than Mars does, so at lunar gravity, the divers struggled to keep their balance and walked awkwardly.

月球比火星重力小，所以在月球的重力下，潛水員們要盡力保持他們的平衡并且步履蹣跚。

But at Martian gravity, the divers had greater traction and stability and could easily adjust to a pace of 1.5 miles per hour.

但在火星的重力下，潛水員們有較大的抓地力和穩(wěn)定性并且能夠輕松適應1.5英里每小時的步速。

As Newman gradually increased the speed of the treadmill, the divers took longer, graceful strides until they comfortably settled into an even quicker pace.

當Newman逐漸增加跑步機速度的時候，潛水員們使用長一些，優(yōu)雅的步伐，直到他們舒服的適應了一個甚至更快的步速。

Newman also noted that at Martian gravity, the divers needed less oxygen. The data Newman collected will help in the future design of Martian space suits.

Newman也注意到在火星的重力下，潛水員需要較少的氧氣。被Newman收集的數據將會在未來有助于火星宇航服的設計。

Compared to lunar space suits, Martian space suits will require smaller air tanks; and, to allow for freer movement, the elbow and knee areas of the space suits will also be altered.

同月球的宇航服相比，火星的宇航服將會要求小一些的空氣箱，并且，允許更加自由的運動，宇航服肘部和區(qū)域也將被改變

Welcome to Everglades National Park.

歡迎來到Everglades國家公園

The Everglades is a watery plain covered with saw grass that's home to numerous species of plants and wildlife.

Everglades是一個被鋸齒草覆蓋著的濕潤的平原，是許多種植物和野生動植物的故鄉(xiāng)。

At one and a half million acres, it's too big to see it all today, but this tour will offer you a good sampling.

因為150萬英畝(大小)，它太大了而不能今天都看完，但是這次旅行將會提供你一個好的樣本。

Our tour bus will stop first at Taylor Slough.

我們的旅游巴士將首先停在Taylor Slough

This is a good place to start because it's home to many of the plants and animals typically associated with the Everglades.

這是一個開始的好地方，因為這里是許多同Everglades有關系的動植物的故鄉(xiāng)。

You'll see many exotic birds， and, of course, our world famous alligators.

你將會見到許多奇異的鳥類，當然還有，我們世界聞名的短吻鱷

Don't worry, there's a boardwalk that goes across the marsh, so you can look down at the animals in the water from a safe distance.

不用擔心，有一條木板路穿過沼澤，所以你可以從一個安全的距離向下看動物。

The boardwalk is high enough to give you a great view of the saw grass prairie.

木板路高到足以給你一個很棒的鋸齒草大草原的景觀。

From there we'll head to some other marshy and even jungle like areas that feature wonderful tropical plant life.

從那里我們將去向另一些濕地乃至叢林似的以美好的熱帶叢林植物為特色的區(qū)域

For those of you who'd like a closer view of the saw grass prairie, you might consider renting a canoe sometime during your visit here.

對于你們誰喜歡鋸齒草大草原近距離景觀的，你們應該考慮在你們參觀的期間租一個獨木舟

However, don't do this unless you have a very good sense of direction and can negotiate your way through tall grass.

然而，別這么做，除非你有非常好的方向感，并且能夠穿過長草找到你的路

We'd hate to have to come looking for you.

我們痛恨不得不來尋找你

You have the good fortune of being here in the winter—the best time of year to visit.

你們冬季在這里是很幸運的—一年中最好的時間來游覽

During the spring and summer, the mosquitoes will just about to eat you alive!

在春夏期間，蚊子將會活生生的吃了你。

Right now they're not so bothersome, but you'll still want to use an insect repellent.

現在它們還沒那么令人討厭，但是你將仍然會想要使用驅蟲劑的

Thank you. It's great to see so many of you interested in this series on "Survival in Outer Space."

謝謝。見到你們這么多人對“生存在外層空間”這個系列感興趣真是太棒了。

Please excuse the cameras, we're being videotaped for the local TV stations.

請原諒這些攝像機，我們正在為地方電視臺錄像。

Tonight I'm going to talk about the most basic aspect of survival—the space suit.

今晚我將要談論關于最基本的生存方面——宇航服

When most of you imagine an astronaut, that's probably the first thing that comes to mind, right?

當你們中的大多數人想象一個宇航員的時候，那個可能是腦子里首先要想到的，對嗎?

Well, without space suits, it would not be possible for us to survive in space.

好，沒有宇航服，對我們來說生存在太空中是不可能的。

For example, outer space is a vacuum—there's no gravity or air pressure; without protection, a body would explode.

舉例來說，外層空間是一個真空空間——沒有重力和氣壓;沒有防護的話，人體將會爆炸。

What's more, we'd cook in the sun or freeze in the shade with temperatures ranging from a toasty 300 degrees above to a cool 300 degrees below zero Fahrenheit.

更重要的是，從酷熱的零上300華氏度到冰冷的零下300華氏度的溫度范圍里，我們會在陽關下被烤熟或者在陰影下被冰封

The space suit that NASA has developed is truly a marvel.

NASA研制出的的宇航服真是個奇跡

This photo enlargement here is a life-size image of an actual space suit worn by astronauts on the last space shuttle mission.

這張放大的照片是個與實物大小一樣的，一件真正的被宇航員在最近一次航天飛機任務中穿過的圖像

This part is the torso.

這個部分是軀干。

It’s made of seven extremely durable layers.

它是由七個極其耐用的層次制成的

This thick insulation protects against temperature extremes and radiation.

這個厚厚的隔離層防御了極端溫度和輻射。

Next is what they call a "bladder" of oxygen that's an inflatable sac, filled with oxygen, to simulate atmospheric pressure.

下一個是所謂的氧氣囊，那是一個可充氣的囊，充滿了氧氣，用來模擬大氣壓強。

This bladder presses against the body with the same force as the Earth's atmosphere at sea level.

這個囊狀物壓在皮膚上，帶著同樣的力量，就像地球空氣在海平面上一樣。

The innermost layers provide liquid cooling and ventilation.

最內層提供了液體冷卻和通風設備。

Despite all the layers, the suit is flexible, allowing free movement so we can work.

盡管有所有這些層，宇航服是有靈活性的，允許自由運動，所以我們能夠工作。

Another really sophisticated part of the space suit is the helmet.

另一個非常復雜的宇航服的部分是頭盔

I brought one along to show you. Can I have a volunteer come and demonstrate?

我?guī)Я艘粋€過來展示給你們。我能找個志愿者過來演示一下嗎?
