;¥qu«:ßforum.liuxuehome.comqö!ä0U2. A: Need a hand with those boxes?
;¥qu«:ßforum.liuxuehome.comqö!ä0UB: That’s OK, I can manage. They’re empty.

;¥qu«:ßforum.liuxuehome.comqö!ä0U3. A: Do you want the windows open or closed?

;¥qu«:ßforum.liuxuehome.comqö!ä0UB: Doctor Miller just sent them to the lab last night. So the earliest they could be

;¥qu«:ßforum.liuxuehome.comqö!ä0UB: I know, but I’m afraid I need another few days. The data was harder to interpret

;¥qu«:ßforum.liuxuehome.comqö!ä0UB: Well, she never comes when I call her, she spills her food, and she sheds all over

;¥qu«:ßforum.liuxuehome.comqö!ä0Ufor the semester.
;¥qu«:ßforum.liuxuehome.comqö!ä0UB: You should check out the new cafeteria. I think there are a few openings left in the

;¥qu«:ßforum.liuxuehome.comqö!ä0UB: Fine. And let’s find a motel too. Instead of continuing on, we can get an early

;¥qu«:ßforum.liuxuehome.comqö!ä0U20. A: Whoops! Did any of my coffee just spill on you?
;¥qu«:ßforum.liuxuehome.comqö!ä0UB: It’s hot! Is that all you have to say?

;¥qu«:ßforum.liuxuehome.comqö!ä0Ulook just like new.

;¥qu«:ßforum.liuxuehome.comqö!ä0UWhat does the man mean?
;¥qu«:ßforum.liuxuehome.comqö!ä0U23. A: I figured it all out. It looks like it’ll take us about six hours to drive from here to

;¥qu«:ßforum.liuxuehome.comqö!ä0UB: It’d be more relaxing to take the train. But I guess we should watch our expenses.

;¥qu«:ßforum.liuxuehome.comqö!ä0UB: Well, maybe. But if I took out the paper that’s fallen down in back, that will help forsure.

;¥qu«:ßforum.liuxuehome.comqö!ä0UOh, hi, Cathy, sure. What’s up?
;¥qu«:ßforum.liuxuehome.comqö!ä0UWell, I’ve been meaning to talk to you about the situation in the office.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI’m not in that very often. It’s so noisy that I can’t work.
;¥qu«:ßforum.liuxuehome.comqö!ä0UThat’s exactly what I’m getting at. We’re supposed to be able to do our preparation
;¥qu«:ßforum.liuxuehome.comqö!ä0Uand marking in that office. But have you notice? Jack constantly has students coming
;¥qu«:ßforum.liuxuehome.comqö!ä0Uin to get help with his course. A lot of people are going in and out.
;¥qu«:ßforum.liuxuehome.comqö!ä0UHas anybody spoken to him about it?
;¥qu«:ßforum.liuxuehome.comqö!ä0UNo, not yet. But someone’s going to have to.
;¥qu«:ßforum.liuxuehome.comqö!ä0UWe can’t really ask him to stop having students come in for help, can we?
;¥qu«:ßforum.liuxuehome.comqö!ä0UNo, of course not. But I’m not able to do my work and neither are you. I imagine it’s
;¥qu«:ßforum.liuxuehome.comqö!ä0Uthe same for the others in the office.
;¥qu«:ßforum.liuxuehome.comqö!ä0UHum… could we ask for a kind of meeting room? When TAs have to talk with the
;¥qu«:ßforum.liuxuehome.comqö!ä0Ustudents, they could go to the meeting room and not use the office. You know, there’s a
;¥qu«:ßforum.liuxuehome.comqö!ä0Uroom down the hall, a rather small room that we could ask to use. It’s only for storing
;¥qu«:ßforum.liuxuehome.comqö!ä0Usupplies.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYou mean that little storage room? Oh, that would be too small.
;¥qu«:ßforum.liuxuehome.comqö!ä0UAre you sure? With the cabinets taken out, it might be bigger than it looks.
;¥qu«:ßforum.liuxuehome.comqö!ä0UCome to think of it, you maybe on to something. I’d like to have a look at that room.
;¥qu«:ßforum.liuxuehome.comqö!ä0UCan we go there now?

;¥qu«:ßforum.liuxuehome.comqö!ä0UI really appreciate you’re feeling me in on yesterday’s lecture.
;¥qu«:ßforum.liuxuehome.comqö!ä0UNo problem. I thought you might want to go over it together. And anyway, it helps
;¥qu«:ßforum.liuxuehome.comqö!ä0Ume review. Hope you’re feeling better now.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI am, thanks. So you said she talked about squid? Sounds a little strange.
;¥qu«:ßforum.liuxuehome.comqö!ä0UWell, actually, it was about the evolution of sea life, a continuation from last week.
;¥qu«:ßforum.liuxuehome.comqö!ä0UThe octopus and the squid descended from earlier creatures with shells. They survived
;¥qu«:ßforum.liuxuehome.comqö!ä0Uby shattering their shells, somewhere between 200 and 500 million years ago.
;¥qu«:ßforum.liuxuehome.comqö!ä0UThat’s a pretty long span of time.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI know. That’s what she said though. To be precise, exactly when they emerged is
;¥qu«:ßforum.liuxuehome.comqö!ä0Uuncertain and why is still unexplained.
;¥qu«:ßforum.liuxuehome.comqö!ä0USome squid are really huge. Can you imagine something that big if it still had a
;¥qu«:ßforum.liuxuehome.comqö!ä0Ushell?
;¥qu«:ßforum.liuxuehome.comqö!ä0UActually, it’s because they lost their shells that they could evolve to a bigger size.
;¥qu«:ßforum.liuxuehome.comqö!ä0UMake sense. But some are really huge. I’ve read about fishermen that caught
;¥qu«:ßforum.liuxuehome.comqö!ä0Usquid that weight over a ton. Did she talk about how that happens?
;¥qu«:ßforum.liuxuehome.comqö!ä0UNot really, but she did mention some unusual cases. In 1933 in New Zealand, they
;¥qu«:ßforum.liuxuehome.comqö!ä0Ucaught a squid… let’s see here… it was 22 yards long. Its eyes were 18 inches across.
;¥qu«:ßforum.liuxuehome.comqö!ä0UCan you imagine?
;¥qu«:ßforum.liuxuehome.comqö!ä0UReminds me about all those stories of sea monsters.
;¥qu«:ßforum.liuxuehome.comqö!ä0UDoctor Simpson thinks there are probably even larger ones that haven’t been found,
;¥qu«:ßforum.liuxuehome.comqö!ä0Ubecause squid are intelligent and fast—so they can easily get away from humans.
;¥qu«:ßforum.liuxuehome.comqö!ä0UMaybe some of those monster stories are true.

;¥qu«:ßforum.liuxuehome.comqö!ä0UCommunity service is an important component of education here at our university.
;¥qu«:ßforum.liuxuehome.comqö!ä0UWe encourage all students to volunteer for at least one community activity before they
;¥qu«:ßforum.liuxuehome.comqö!ä0Ugraduate. A new community program called “One on One” helps elementary students
;¥qu«:ßforum.liuxuehome.comqö!ä0Uwho’ve fallen behind. You education majors might be especially interested in it, because
;¥qu«:ßforum.liuxuehome.comqö!ä0Uit offers the opportunity to do some teaching—that is tutoring in math and English.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYou’ll have to volunteer two hours a week for one semester. You can choose to help
;¥qu«:ßforum.liuxuehome.comqö!ä0Ua child with math, English or both. Half-hour lessons are fine, so you could do a half hour
;¥qu«:ßforum.liuxuehome.comqö!ä0Uof each subject two days a week.
;¥qu«:ßforum.liuxuehome.comqö!ä0UProfessor Dodge will act as a mentor to the tutors. He’ll be available to help you with
;¥qu«:ßforum.liuxuehome.comqö!ä0Ulesson plans or to offer suggestions for activities. He has office hours every Tuesday and
;¥qu«:ßforum.liuxuehome.comqö!ä0UThursday afternoon. You can sign up for the program with him and begin the tutoring
;¥qu«:ßforum.liuxuehome.comqö!ä0Unext week.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI’m sure you’ll enjoy this community service and you’ll gain valuable experience at the
;¥qu«:ßforum.liuxuehome.comqö!ä0Usame time. It looks good on your resume too, showing that you have experience with
;¥qu«:ßforum.liuxuehome.comqö!ä0Uchildren and that you care about your community. If you’d like to sign up or if you have
;¥qu«:ßforum.liuxuehome.comqö!ä0Uany questions, stop by Professor Dodge’s office this week.

;¥qu«:ßforum.liuxuehome.comqö!ä0UI hope you’ve all finished reading the assigned chapter on insurance, so that you’re
;¥qu«:ßforum.liuxuehome.comqö!ä0Uprepared for our discussion today. But before we start, I’d like to mention a few things
;¥qu«:ßforum.liuxuehome.comqö!ä0Uyour text doesn’t go into.
;¥qu«:ßforum.liuxuehome.comqö!ä0UIt’s interesting to know that insurance has exited in some form for a very long time.
;¥qu«:ßforum.liuxuehome.comqö!ä0UThe earliest insurance policies were what were called bottomry contracts. They provided
;¥qu«:ßforum.liuxuehome.comqö!ä0Ushipping protection for merchants as far back as 3000 BC. In general, the contracts
;¥qu«:ßforum.liuxuehome.comqö!ä0Uwere often no more than verbal agreements. They granted loans to merchants with the
;¥qu«:ßforum.liuxuehome.comqö!ä0Uunderstanding that if a particular shipment of goods was lost at sea, the loan didn’t have to
;¥qu«:ßforum.liuxuehome.comqö!ä0Ube repaid. Interest on the loans varied according to how risky it was to transport the
;¥qu«:ßforum.liuxuehome.comqö!ä0Ugoods. During periods of heavy piracy at sea for example, the amount of interest and
;¥qu«:ßforum.liuxuehome.comqö!ä0Uthe cost of the policy went up considerably.
;¥qu«:ßforum.liuxuehome.comqö!ä0USo you can see how insurance helped encourage international trade. Even the most
;¥qu«:ßforum.liuxuehome.comqö!ä0Ucautious merchants became willing to risk shipping their goods over long distances, not
;¥qu«:ßforum.liuxuehome.comqö!ä0Uto mention in hazardous weather conditions when they had this kind of protection
;¥qu«:ßforum.liuxuehome.comqö!ä0Uavailable.
;¥qu«:ßforum.liuxuehome.comqö!ä0UGenerally speaking, the basic form of an insurance policy has been pretty much the
;¥qu«:ßforum.liuxuehome.comqö!ä0Usame since the Middle Ages. There are four points that were salient then and remain
;¥qu«:ßforum.liuxuehome.comqö!ä0Uparamount in all policies today. These were outlined in chapter six and will surface the
;¥qu«:ßforum.liuxuehome.comqö!ä0Ubasis for the rest of today’s discussion. Can anyone tell me what one of those points
;¥qu«:ßforum.liuxuehome.comqö!ä0Umight be?
;¥qu«:ßforum.liuxuehome.comqö!ä0U43. What is the purpose of the instructor’s talk?
;¥qu«:ßforum.liuxuehome.comqö!ä0U44. Who were the first insurance contracts designed to protect?
;¥qu«:ßforum.liuxuehome.comqö!ä0U45. What does the instructor say determine the cost of early insurance policies?
;¥qu«:ßforum.liuxuehome.comqö!ä0U46. What does the instructor say about current insurance policies?
;¥qu«:ßforum.liuxuehome.comqö!ä0UQuestions 47-50 Listen to a talk on the radio about a research project.
;¥qu«:ßforum.liuxuehome.comqö!ä0ULocated at the NASA research center in Iowa, there is a 5000 gallon vat of water.
;¥qu«:ßforum.liuxuehome.comqö!ä0UAnd inside the tank is an underwater treadmill designed by Davan Newman, an
;¥qu«:ßforum.liuxuehome.comqö!ä0Uaerospace engineer. For four years, Newman observed scuba divers as they stimulated
;¥qu«:ßforum.liuxuehome.comqö!ä0Uwalking on the moon and on Mars on her underwater moving belt. She wanted to
;¥qu«:ßforum.liuxuehome.comqö!ä0Udiscover how the gravity of the moon and of Mars would affect human movement.
;¥qu«:ßforum.liuxuehome.comqö!ä0UTo do this, Newman attached weights to the divers and then lowered them into the
;¥qu«:ßforum.liuxuehome.comqö!ä0Utank and onto the treadmill. These weights were carefully adjusted so that the divers
;¥qu«:ßforum.liuxuehome.comqö!ä0Ucould experience underwater the gravity of the moon and of Mars as they walked on the

;¥qu«:ßforum.liuxuehome.comqö!ä0Uon the moon. The moon has less gravity than Mars does. So at lunar gravity the divers
;¥qu«:ßforum.liuxuehome.comqö!ä0Ustruggled to keep their balance and walked awkwardly. But at Martian gravity, the divers
;¥qu«:ßforum.liuxuehome.comqö!ä0Uhad greater traction and stability and could easily adjust to a pace of 1.5 miles per hour.
;¥qu«:ßforum.liuxuehome.comqö!ä0UAs Newman gradually increased the speed of the treadmill, the divers took longer,
;¥qu«:ßforum.liuxuehome.comqö!ä0Ugraceful strides until they comfortably settled into an even quicker pace. Newman also
;¥qu«:ßforum.liuxuehome.comqö!ä0Unoted that at Martian gravity, the divers needed less oxygen.
;¥qu«:ßforum.liuxuehome.comqö!ä0UThe data Newman collected will help in the future design of Martian spacesuits.
;¥qu«:ßforum.liuxuehome.comqö!ä0UCompare to lunar spacesuits, Martian spacesuits will require smaller air tanks. And to
;¥qu«:ßforum.liuxuehome.comqö!ä0Uallow for freer movement, the elbow and knee areas of the spacesuits will also be altered.
;¥qu«:ßforum.liuxuehome.comqö!ä0U47. What did Newman change so that the divers could experience different gravity levels?
;¥qu«:ßforum.liuxuehome.comqö!ä0U48. Why will Martian spacesuits be designed differently from lunar spacesuits?
;¥qu«:ßforum.liuxuehome.comqö!ä0U49. What happened to the divers at Martian gravity when the speed of the treadmill was
;¥qu«:ßforum.liuxuehome.comqö!ä0Uincreased?
;¥qu«:ßforum.liuxuehome.comqö!ä0U50. What is one way that the design of Martian spacesuits will differ from lunar
;¥qu«:ßforum.liuxuehome.comqö!ä0Uspacesuits?
