课件15张PPT。 Unit 3 Tales of the unexplained Welcome to the unit flying saucer 飞碟UFO (Unidentified Flying Objects) 不明飞行物The origin(起源) of the names:In the United States, the first flying saucers
were reported on June 4, 1947, by a private
plane pilot(飞行员).He saw nine objects
traveling in the sky. Each was disk shaped
and very bright. Because their movements
were compared to (比做)those of a
“saucer (碟子)skimming across the water”,
newspaper reporters called them
“flying saucers”.Some weeks after the first reported
（报道的） sighting（目击）, the United States Air Force was given the job of investigating（调查） all the reports of flying saucers.
Because of the confusing（令人费解的） variety of shapes, sizes, and colors reported ,
the Air Force adopted（采用） the term “Unidentified Flying Objects” (UFO)
to describe them. Some believe them to be spaceships from other planets. Aliens visit the earth by UFOs and they try to have a better understanding of our human beings.
Others insist that they are a secret type of aircraft being built on earth. Maybe there will be a new kind
of planes, man-made satellites ,or experimental(实验的) missiles(导弹).
Many people maintain( 坚持说) that they are only natural phenomena(自然现象 ) happening under special temperature(温度), light, or weather conditions. What do you think of UFOs? Thousands of people all over the world claim（声称） to have seen them. What do you think of UFOs?All reports agree that the strange objects move
at extremely（非常地） high speeds and
fail to follow the laws of motion（运动）
by reversing(逆转) direction instantly
without slowing down.（他们不遵循一般的运动
规律，他们改变方向运动的时候速度非常的快，
丝毫没有减速。）Several sightings, mainly of footprints, have been reported by westerner explorers throughout the years. Yet none of them have been supported with evidence in any way. The yeti is a
humanlike monster
who is supposed to live
in the Himalayas,the
highest Mountain range
in the world.On the 21st December 1933, the Daily Mail carried the following headline: “Monster of Loch Ness is not a Legend but a Fact.” The hunter said: “It is a four fingered beast and it has feet or pads of eight inches across. I judge it to be a powerful soft footed animal about 20 feet in length....... I am sure that it can breathe like a crocodile(鄂鱼) with just one nostril(鼻孔) out of the water." The Great Pyramid is the oldest structure in existence( 存在).
It is the only remnant(遗留的) of the Seven Wonders of the World.
It is the tomb of Khufu, the ruler of a highly structured society.
Not much is known about it.
what is known to us?
It is very hard to realize how big the Great Pyramid is.
It has over 2,300,000 blocks of solid stone .These huge
stone blocks weight an average of two and a half tons
each, as much as a small car. Some even weight fifteen
tons. Without machinery, the ancient
Egyptians cut and moved and
lifted each of these stones.
It took more than 100,000 slaves
twenty years to build
the Great Pyramid.
what is unknown to us?
It is very hard to answer who built the Great Pyramid .
Whoever built the Pyramid knew the Earth well:
the average height of the continents(大陆),
and the center of the land mass.
The average height of land above sea level
(海平面)， as can be measured only by modern-day satellites and computers,
happens to be 5,449 inches.
That is the exact height of the Pyramid.The Pyramid is located at(位于) the exact center of the Earth's land mass. They were able to build something that we still cannot do with today’s advanced science and technology, and they were able to tie all these things together in this single structure. Someone may argue that we were visited
by scientifically advanced(先进的) beings from
outer space who taught us their technology. How did these stones stand upright(直立)?
The truth is nobody really knows. It required
sheer muscle power and hundreds of men to
move one of these ,the heaviest of them
weighing probably about 45 tons.
There are some wonderful myths and legends.
