As you know,feldspars are the most abundant minerals and are divided into a number of types,these fist samples are *.Notice that they vary in colour from white to pink to red.This glassy one is found in volcanic rock.

You can identify it by its bright green colour,it is often used in jewelry and really is quite attractive.These final samples are all plagioclase feldspars.Many plagioclases are very rare,so I am particularly proud of the variety in my collection.I ‘ve also brought a few slides of some large mineral samples ,and if you will turn out the lignt now, I’d like to show them to you.0 A1 W0 U- t4 t* j- r$ T

Welcome to yellow stone national park, before we begin our nature walk today. I ‘d like to give you a short histroy of our national park service. The national park serive began in the late 1800’s, A small group of explorers has just completed a month-long exploration of the region that is now the yellow stone. They gathered around a camp fire, and after hours of discussion, they decided that they should not claim this land for themselves, They felt it should be accessible to everyone.

/ E( n" c: y) G+ q3 S2 F' A% T. Z* _6 c- q3 [
So they began a campaign to preserve this land for everyone’s enjoyment. Two years later, in the late 19 century, an act of Congress signed by president Ulysses proclaimed the yellow stone region a public park. It was the first national park in the world. After yellow stone became a public park, many other areas of great scenic importance were set aside, and in 1916 the national park service was established to manage these parks. As a park ranger, I am a employee of the national park service. In a national park, park rangers are on duty at all times to answer questions and help visitors in many difficulty. Nature walks, guided tutors, and campfire talks are offered by special training staff members, the park service also protect the animals and plants within the parks.

I need to make sure you understand how to get housing for next year. When you entered as first-year students this year, the school assigned you to a dorm and roommate, but next year, as returning students, you will choose both your roommate and your dorm. But whether or not you actually get to live in your first choice, depends on what number you or your roommate draws in the lottery system. The system gives priority to the students who have been here longest. Forth year students get the first block of numbers, third years get the second block and second years, like you will be, get the third. The lower the number you draw, the sooner you choose. Number one gets the first choice, number two gets the second choice and so on.: P, G* t( p$ c+ j+ L% M! P3 T

6 @+ W7 b9 `$ c7 pYou can use either your own or your intended roommate’s number to make your room choice. If your roommate for next year has been this school longer than you have, they will be in a better block of numbers, and so will have a better number than any second year student. But most of you will probably be rooming with other second year students, and so neither of you may have a great number. You may not get into your first or even second choice. Of course, if you have made plans to live off campus, you don’t need to entering the lottery at all. Dorm space will be especially tight this year because the dorms on north campus will be closed for renovations . This means that those of you who draw worst numbers won’t be able to get dorm housing at all. In that case, the housing office will help you find off-campus housing.

4 n. Z8 w% R" V* Z( M1 p3 iBefore I tell you about the interesting discovery related to Tyrannosaurus rex, I need to review something we studied last semester – the difference between what are commonly called cold-blooded and warm-blooded animals. In warm-blooded animals, birds and mammals, for example, the body temperature normally stays within a narrow range, on matter what the outside temperature is. As a result, a warm-blooded animal is usually active in both cold and hot weather, because its body temperature can adjust to the temperature of its environment. On the other hand, cold-blooded animals, such as most reptiles, amphibians,and insects, are unable to create encough heat internally to raise their temperature above the temperature of the environment. So, for example, the temperature of a cold-blooded animal falls when the environment is cool.
  L) l$ ~+ U$ Z% H+ _I hope that this distinction is clear, now , moving on to Tyrannosaurus rex. You may know that dinosaurs ,being reptiles,are generally believed to have been clod-blooded, well, a recent research study found that the chemical composition of the bones of the tyrannosaurus rex was consistent with the bones of an animal that has a very narrow range of internal temperature, indicating that it was probably warm-blooded.4 `& A% h- V, d5 |' `

This topic should be of special interests since I know that many of you are already at the forefront of workplace technology. For example, let’s have a show of hands to see how many people here telecommute at least part of the time. En, I see eight hands raised, well, you eight folks who work at home and communicate with your office via
, p, R6 h( K4 c  w' ~% mcomputer represent one of the trends Ms. Lambert has described,that people are becoming less tied to the workplace.5 Y, {# X! T- n4 O) O) I
One of the important tools for telecommuting is electronic mail or email. Email lets you send and receive message almost immediately on your computer , but you control when you read them and when you respond to them, This technology allows people to have more control over time than when relying solely on the telephone. Our guest tonight will discuss how these important changes will alter the way we work, but before turning the floor over to Ms. Lambert, I would just like to remind you that she will be available to answer any individual questions at the reception immediately following this talk.: ^- U7 A( _+ r/ h: d6 x; U

I’m sure almost everyone of you looked at your watch or at a clock before you came to class today, watches and clocks seem as much a part of our life as breathing or eating,and yet , did you know that watches and clocks were scarce in the United States until the 1850’s?

- }5 ^- Z; U, q5 |3 u" k! icitizens simply couldn’t afford a personal timepiece. Well into the 1800’s, in European and the United States, the main purpose of a watch, which ,by the way, was often on a gold chain, was to show others how wealthy you were. The word, wristwatch, didn’t even enter into English language until nearly 1900.
- k9 B0 |) W& ~- Q( C( k, {By then, the rapid pace of industrialization in the United States, meant that measuring time had became essential , how could the factory worker get to work on time unless he or she knew exactly what time it was? Since the efficiency was now measured by how fast a job was done, every one was interested in time, and since industrialization made possible the manufacture of large quantities of goods, watches became fairly inexpensive. Furthermore, electric lights kept factories going around the clock, being on time had entered the language and life of every citizen.

; _3 A7 E) w) W0 H2 @. VSo, why did what is now called modern dance begin in the United States? To begin to answer this question, I will need to backtrack（返回） a little bit and talk about classical ballet.* ?0 L1 j9 |8 k4 d, [" R5 O
5 K" b2 d# m: v- h8 F: @% j
By the late 1800’s, ballet had lost a lot of its popularity, most of the ballet dancers who performed in the United States were brought over from Eroupe, they performed using the rigid techniques that had been passed down through the centuries. Audience and dancers in the United States were earger for their own contemporary dance form. And so, around 1900, dancers created one. % c; {5 N3 ]1 s0 X

+ C8 i7 D2 L  }# X" B8 e( n8 vSo how was this modern dance so different from classical ballet. Well, most notably, it wasn’t carefully choreographed , instead, the dance depended on the improvisation and free personal expression of the dancers. Music and scenery were of little importance to the modern dance, and lightness and movement wasn’t important either. In fact, modern dancers made no contempt at all to conceal the effort involved in a dance step. ; n3 W' |! D8 w& ~
" X- o# t$ b0 U$ F' x- i4 I& b4 Y7 O* b
But even if imrovisation appealed to audiences, many dance critics were less enthusiastic about the performances. They questioned the artistic integrity of dancers who were not professionally trained and the artistic value of works that had no formal structure. Loie Fuller, after performing Fire dance, was described as doing little more than turning round and round like an eggbeater. Yet the free personal expression of the pioneer dancers is the basis of the controlled freedom of modern dance today.( X  Z, p# a0 T
