Special Effects
What are special effects? Do you enjoy movies that use a lot of special effects Dinosaurs（恐龙） from the distant past?Space battles from the distant future!There has been a revolution in special effects,and it has transformed the movies we see.
The revolution began in the mid 1970s with George Lucas's Star Wars,a film that stunned（使震惊）audiences. That revolution continues to the present, with dramatic changes in special-effects
technology.The company behind these changes is Lucas's Industrial Light&Magic(ILM).And the man behind the company is Dennis Muren,who has worked with Lucas since Star Wars.
Muren's interest in special effects began very early.At the age of 6,he was photographing toy dinosaurs and spaceships.At 10,he had an 8 millimeter movie camera and was making these things move through stop-motion.(Stop-motion is a process in which objects are shot with a camera, moved slightly,shot again,and so on.When the shots are put together,the objects appear to move. )
Talk to Muren and you'll understand what ILM is all about:taking on new challenges.By 1989,Muren decided he had pushed the old technology as far as it would go.
He saw computer graphics（图像）(C
G) technology as the wave of the future and took a year off to master it.
With CG technology,images can be scanned into a computer for processing,for example,and many separate shots can be combined into a single image.CG technology has now reached the point, Muren says,where special effects can be used to do just about anything so that movies can tell stories better than ever before. The huge success of Jurassic Park and its sequel（续集）,The Lost World,the Stars of which were computer-generated dinosaurs,suggests that this may very well be true.
At the age of 10,Muren was able to use computer graphics technology to make things move.
A.Right
B.Wrong
C.Not mentioned

[简答题] There are examples of (0) can be done by the retailer within his store, but perhaps the biggest opportunity for cost-reduction stems (31) cooperation between manufacturer and distributor in analyzing the total costs involved in moving the product from the factory to the shopper’’s basket.

[填空题]
The first two stages in the development of civilized man were probably the invention of primitive weapons and the discovery of fire, although nobody knows exactly when he acquired the use of the latter.
41)______Animals have a few cries that serve as signals, but even the highest apes have not been found able to pronounce words, even with the most intensive professional instruction. The superior brain of man is apparently a necessity for the mastering of speech. When man became sufficiently intelligent, we must suppose that he gradually increased the number of cries for different purposes. It was a great day when he discovered that speech could be used for narrative. There are those who think that in this respect picture language preceded oral language.
