Dr. Thomas? This is Keef Bradley from the daily news. I’d like to ask you some questions about the new official standard weight that you purchased. 小马过河% U2 U: m" g5 l

Well, the people in our department use it to check the scales all over the country. The department of weights and measures, we are a government agency. It’s our responsibility to see that all the scales measure a kilogram accurately so this is the way we use to adjust the scales. / B$ A& [5 V# f" P
How did you check the scales before? 小马过河& ]5 N: v& Z5 k- i) g
We have an old standard weight that we used to use. It had to be replaced because it was imprecise. You see it was made of poor quality metal that was too porous. It absorbed too much moisture. 3 J4 F9 A* _, q. Y1 E. [
Oh. So when the weather was humid it weighed more and when it was dry it weighed less. www.xiaomaguohe.net! ^! P5 c8 j& |/ l. {
Exactly. And that variation can affect the standards of the whole country. So our department had the new weight made out of higher quality metal. [小马过河-新托福专业备考社区]. E" c+ b3 E$ ]/ O$ \% V  l- n
How much did it cost? TOEFL,IBT,托福,新托福,机经,小马过河,留学,美国,海外* J5 C' h! V: k# Y1 r
About 45 thousand dollars.
9 M- `4 {0 r' ?2 S# ~; e" Dwww.xiaomaguohe.net45,000 dollars? For a one kilogram weight? That’ more expensive than gold. Is it really worth that much?
: c' K" M0 Q$ N5 E8 n; |& ~/ Cwww.xiaomaguohe.netI’m sure it is. Industries depend on our government agency to monitor the accuracy of scales so that when they buy and sell their products there is one standard.

Some upscale homes now incorporate natural round logs in sealing beams and walls. People seem to think that the rounded logs give their homes a cozy warm atmosphere.

: V# q/ P5 s8 h7 uTOEFL,IBT,托福,新托福,机经,小马过河,留学,美国,海外Log cabins were first built in the late 1600s along the Delaware river valley. The European immigrants who settled there brought centuries’ old traditions of working with logs. And in this heavily wooded area logs were the material in hand. Log cabins were the most popular in the early 1800s with the settlers who were moving west. They provided the answer to the pioneer’s need for a safe and sturdy home that an ordinary family could build quickly. They had dirt floors and sliding boards for windows. But the log buildings that have probably had most influence on modern architects are those of the mountain retreats of wealthy New Yorkers. These country houses which were popular in the early 1900s typify what’s known as the Adoroundyx style. Now let’s look at those slides. TOEFL,IBT,托福,新托福,机经,小马过河,留学,美国,海外; t8 L0 |- L  @0 h+ v

- C8 L" q! P1 H+ e) j. q [小马过河-新托福专业备考社区]The old kind of road is a long lost trail between the Canadian province of Quebec and Maine in the northeast corner of the United States. Yes it really was lost and finding it again was a complex process that involved state of our technology: how the location of the roads was pinpointed was very interesting. And I’ll return to it as soon as I gave you a little background information. The road was begun in 1817, a few years before Maine even became a state. At the time Quebec was a major market for livestock, crops and fish. So a road to Quebec was seen by officials in Maine as necessary for trade. For about 20 years the movement of people and goods was mostly from Maine to Quebec, and then the trend reversed as thousands of Canadians immigrated to Maine to escape poor crops, the lack of jobs and the threat of disease. I think it was a color epidemic. Besides its negative reasons major building projects in Maine also made the state very attractive for the Canadians who needed work. I should stress though that immigration during that period went in both directions. In fact the flow of people and goods went completely unhindered. There wasn’t even a border post until around 1850. The people of the time saw Maine and Quebec as a single region mainly because of the strong French influence which is still evident in Maine today. Eventually the road fell into disuse as a major railway was completed. Finally people simply forgot about it and that’s how it came to be lost.

OK, in the last class we talked about the classification of trees and we ended up with a basic description of angiosperm. You remember that those are plants with true flowers and seeds that develop inside fruits. The common broad leaf trees we have on campus fall into this category. But our pines don’t. Now I hope you all followed my advice and wore comfortable shoes because as I said today we are going to do a little field study. To get started let me describe a couple of broadleaf trees we have in front of us. I’m sure you’ve all noticed that this big tree next to Brand Hall. It’s a black walnut that must be 80 feet tall. As a matter of fact there is a plaque identifying it is the tallest black walnut in the state. And from here we can see the beautiful archway of trees at the commons. They are American elms. The ones along the commons were planted when the college was founded 120 years ago. They have distinctive dark green leaves that look lopsided because the two sides of the leaf are unequal. I want you to notice the elm right outside the Jackson Hall. Some of the leaves have withered and turned yellow, maybe due to Dutch elm disease. Only a few branches seem affective so far but if this tree is sick it’ll have to be cut down. Well, let’s move on and I’ll describe what we see as we go.
