Since we’ve been discussing alternative fuels lately, I wanted to pass on to you some information I read about a new fuel that’s been in the news a lot lately. It's called A-21.
It’s composed of water and chemical know as naphtha. It seen (seems) to be a very promising fuel because it is much cleaner than gasoline that we use today. That’s not to say it doesn't pollute, but it is cleaner. A-21 isn't like some other alternative fuels that require completely new type of en (engines). A-21 still works in regular, everyday combustions engines, like the ones in cars with mechanical modification. So changing over wouldn't be a big deal.
You might doubt some of these claims as many researches (researchers) have. Some people feared that because it contains about 45 percentage (percent) water it would freeze in the winter. But a small amount of antifreeze was added into it, so (and that) seen (seems) to have solved this problem.
A-21 has recently undergone three (street) test since (in) buses in Reno, Nevada. So far it seems to work just fine. This is a good thing, especially in Nevada, because the state government there has passed the (a) law that require (requiring) a large percentage of vehicles in Nevada run on alternative fuels, A-21 should help.

潜在缺点：含水量高，在冬天容易结冰！不过antifreeze可以解决

11.18 听写（tornado)


The winds of tornado are the most violated (violent) and destructed (destructive) ones on the earth. Any of you who might see (have seen) one knows very well that how frightening and powerful they are. What is interesting about them is that scientists don’t actually know exactly why the tornados occur. We do know, however, what happens when tornados are formed. As you remember, a front occurs when cold (cool), dry air from the north means (meets) warm, humid air coming from the south, from gulf of Mexico, for tornados to (in) the united state. Where these air masses meet, a narrow zone of storm clouds develops, and thunderstorms, and sometime tornados, occur.
How was (is) this violent weather produce? Well, a mass of warm, humid air raise (rises) rapidly. As it raises (rises), more warm air rushes in to the places (replace) it. This rushing (inrushing) air also rises, and in some cases, especially when they are (there is) extreme thermal instability, begins to rotate. When this happens, the rotating air forms a tornado. Even if you’ve seen tornados only in moving (movies), you know that they can demolish buildings in seconds. This is possible because when a tornado passes over a house, it sucks up air for (from) around the house and so the air pressure outside the house drops rapidly. Inside, pressure remains the same. So, the air pressure inside is greater than the air pressure outside. The result is that the building explodes outward. Next, we'll talk a little bit about how new technological developments are being used to try to predict tornados

1、主题：tornado 知道形成，但是不知道为什么会发生
2、介绍Tornado的发生 cool dry air meet warm humid air
3、介绍为什么tornado会造成这么大的伤害
air inside is greater than the air outside
4、Next: technological development to predict tornado

Located in （at） NASA research center in Iowa is a 5,000-gallon vat of water, and inside the water (tank) is an underwater treadmill designed by DN, an aerospace engineer. For four years, DN observed scuba divers as they simulated as walking on the moon and on marks on her under water moving belt. She wanted to discover how the gravity of moon and of mars would affect human movement.
To do this, Newman attached weights to the divers and then lowered them into the tank and onto the treadmill. These weights were carefully adjusted so that the divers could experience on underwater the gravity of the moon and of the mars as they walked on the treadmill. DN concluded that walking on the Mars will probably be easier than walking on the moon. The moon has less gravity than Mars does, so at lunar gravity, the divers struggled to keep their balance and walked awkwardly. But at Martian gravity, the divers have (had) greater attraction (traction) and stability and could easily adjust the (to) the pace to (of) 1.5 miles per hour. As DN gradually increased the speed of the treadmill, the divers took longer, graceful strides until they comfortably settled into an even quicker pace. DN also notice (note) that at Martian gravity, the diver needed less oxygen.

The data DN collected will help in the future design in (of) Martian space suits. Compared to lunar space suits, Martian space suits will require smaller air tanks; and to allow for free (freer) movement, the elbow and knee areas in (of) the space suits will also be altered.

Located at the NASA Research Center in Iowa is a 5,000-gallon vat water, and inside the tank is an underwater treadmil designed by Dava Newman, an aerospace engineer. For four years Newman observed scuba divers as they simulated walking on the Moon and on Mars on her underwater moving belt. She wanted to discover how the gravity of the Moon and of Mars would affect human movement.
To do this, Newman attached weights to the divers and then lowered them into the tank and onto the treadmill. 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. Newman concluded that walking on Mars will probaly be easier than walking on the Moon. The Moon has less gravity than Mars does, so at lunar gravity, the divers struggled to keep their balance and walked awkwardly. But at Martian
gravity, the divers had greater traction and stability and could easily adjust to a pace of 1.5 miles per hour. As Newman gradually increased the speed of the treadmil, the divers took longer, graceful strides until they comfortably settled into an even quicker pace. 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.

Most people think
of astronomers
as people who spend their time in cold observatories
peering
through telescopes every night. In fact, a typicalastronomer spends most of his or her time analyzing data and make
(may) only be at the
telescope a few weeks
in
(of)
the year. Some of astronomers work on purely
theoretical problem and never use a telescope at all.


You might now
(not)
know how weried
(rarely)
images
to
(are)
viewed derectly throught telescope. The most common way to observe the skies is to photogragh them. The process is very simple. First, the
(a)
photogragh place
(photographic plate) is coated with a light-sensitive material. The
plate is positioned
so that the image recieved by telescope is recorded on it. And then the image can be develop, large
(enlarged) and published, so that
many people can study it.


Because many
(most)
astronomical objects are very remote, the light we recieve from them
is rather feeble. But by use
(using) telescope
in
(as) a camera, long time exposures can be made. In this way, objects can be photographed that are hundreds times too faint to be seen by just lookin through a telescope.

Thank you. It is great to see so many of you is interesting in this series on "survival in outer space". Please excuse the cameras, we have been (we're being) videotaped from the local TV stations.
Tonight, I am going to talk about the most basic aspect of survival, the space suit. When most of you imagine an astronaut, that is probably the first thing that comes to mind, right? Well, without space suits, it would not be possible for us survive in space. For example, outer space is a vacuum, there is no gravity or air pressure. Without protection, a body would be explode. What's more, we'd cook in the sun and (or) freeze in the shade with tempeartures rang (ranging) from a toasting (toasty) 300 dgrees above to a cool 300 dgrees blow zero Fahrenheit.
The sapce suit that NASA has developed is truely a marvel. This photo enlargement here is a life-size image that (of) an actual space suit worn by astronauts on the last shuttle mission. This part is T. It's make (made) up of 7 extremely durable layers. These (this) thick insulation protects against temperature extremes and radiation. Next is what they calles "B"of oxygen, that is an inflatable sac, filled with oxygen, to simulate atmospheric pressure. This B protects (presses) against body with the same force as the earth's atmosphere sea level. The innermost layers provide liquid cooling and ventilation. Despite all the layers, the suit is flexible, allowing free movement, so we can walk.
Another really sophisticated part of space suit is H. I brought one along to show you. Can I have a volunteer come and demonstrate?

Good evening, my name is PJ and on behalf of modern dance club.
I'd like to welcome you to tonight's program. The club is pleased to present the TV version of "kw", "T rock ballet". This video veison of ballte has been even more successful with audience than the original theather production. It include slow motion, animation and stop-action freezes that really help andience understand the dance.
The title of the piece refers to K, who died on wheel in 307 AD. Nowadays, KW is also a kind of firework, it looks something like pinwheel. Anyway,the dance is certainly full of fireworks. You see how T explores one family's attempt to confrot the violence in modern life. The center symbol of the work is pineapple. But it exactrly what it present has always created a lot of controversy. As you watch, see if you can figure it out.
The music for this piece is full of the rhythmic energy and (of) rock music. It was composed by DB of the rock band talking heads. And the lead dancer in this version is S, who is perfectly suited for (to) T's adventure (adventurous choreography).
Following the video, the dance teacher will lead a discussion about the symbolism Mrs T use. We hope you can stay for that. So enjoying tonight's video and thank for your support.

11.20 （Monticello）
Before we starting our tour of Monticello, I’d like to give you some historical facts that might help you appreciate what you see today even more.
Monticello is (was) the very much loved home of J for over 50 years. J, who was, of course, was a president, with (was) also a great reader and language enthusiasm. He read widely on different subjects, including architecture. He wasn’t formally trained in architecture, but as a result of his study of (and) observing (observation of) other buildings, he was able to help design and build the house. He chose the site himself, naming” Monticello”, which is mean “little mountain” in Italian. In fact, many of ideas behind the design also came from Italian architect P, who lived in the 16s and who had a great influence on the architecture of England. However, J ignored one of P’s principle, that is not to build in a high place. Monticello’s elevation made the transportation of what we needed at the house, for example food, especially difficult. But the view from the state (estate) would not be particular (spectacular) if J had followed P’s advice. There is really no boundary between the house and nature around it. So J was able to look out on his beloved state of Virginia from his advantage (wonderful vantage) point.
Now, we’ll go on to J’s library.

11.20 （thatching）

Welcome to the Four Winds Historical system farm, where traditions of the parts (past) are preserved for visitors like you. Today, our master thatching will begin giving this bar behind me a sturdy thatched roof, able to stand (withstand) heavy winds and last for (up to) hundred years. How do they do it? Well, in a nutshell, thatching involves covering beams or rafters, the wooden skeleton of a roof, with reeds and S.
Our thatches here have harvested their own natural materials for the job. The boundary (bundle) of water reeds you see lying over there beside the barn.
Thatching is certainly uncommon in the United State today. I guess that’s why so many of you have come to see this demonstration. But it wasn’t always that way. In 17s, the colonist here thatched their roofs with reeds and S, just as they had done in England. After a while, though, they began to replace the thatch with wooden shingles because wood was so plentiful. And eventually, other roofing material like stone, slate, and clay tiles came to use.
It is a really (real) shy (shame) that most people today don’t realize how strong and long lasting a thatched roof is. In Ireland, where thatching is still practiced, the roofs can survive winds of up to110 miles per hour. That is because the reeds and S are so flexible. They bend but don’t break in the wind like other materials can.
Another advantage is that the roofs keep the house cool in the summer and warm in the winter.
And then, of course, there is the roof’s longevity. The average is 6 year, but they can last hundreds years. With all these reasons to study (start) thatching roof again, wouldn’t it be wonderful to see this disappearing craft return to popularity.

11.20 (coffee)


A lot of people in the United State are coffee drinkers. Over the last few years, a trend has been developing to introduce premium, specially blended coffees, known as G coffee, into the American market.
Boston seems to have been the birthplace of this trend. In fact, major G coffee merchants from other cities, like Seattle or San Francisco, came into Boston, but  (where) today they’re engaged in a kind of “coffee war “ with Boston’s merchants. They are all competing for a significant share of G coffee market.
Surprisingly, the competition among these leading G coffee businesses will not hurt any of them. Experts predict that G coffee market in the United State is growing and will continue to grow, to the point that G coffee will soon catch (capture) half of what’s now a 1.5-million-dollar
and will be an 8-million-dollar market by 1999.
Studies have shown that coffee drinker who convert to G coffee seldom go back to the regular brands found in supermarket. As a result, these brand will be the real loser in G coffee competition.
