回答题。

Coming Soon to a Theater Near YouI

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 object 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)(CG)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 processin9，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 Word，the stars of which were computer-generated dinosaurs，suggests that this may very well be true．

The special-effects revolution began in the mid-1980s with Star Wars．查看材料

Leading a dog’s life in America isn’t such a bad thing. Many grocery stores sell pet f

oods to owners eager to please their pets. In Houston, Texas, dogs can have their dinner delivered to their homes, just like pizza. Well-to-do canines can attend doggy daycare centers while their owners work. Pets can even accompany their owners on vacation. Fancy hotels are beginning to accommodate both man and beast. Furry guests in hotels can enjoy gourmet meals served on fine china and sleep in soft beds.

Beneath the furry luxuries, there lies a basic American belief: Pets have a right to be treated well. At least 75 animal welfare organizations exist in America. These provide care and adoption services for homeless and abused animals. Vets can give animals an incredible level of medical care for an incredible price. To pay for the high-tech health care, people can buy health insurance for their pets. And when it’s time to say good -bye, owners can bury their pets in a respectable pet cemetery.

The average American enjoys having pets around, and for good reason. Researchers have discovered that interacting with animals lowers a person’s blood pressure. Dogs can offer protection from burglars and unwelcome visitors. Cats can help rid the home of unwanted pests. Little creatures of all shapes and sizes can provide companionship and love. In many cases, having a pet prepares a young couple for the responsibilities of parenthood. Pets even encourage social relationships: They give their owners an appearance of friendliness, and they provide a good topic of conversation.

Pets are as basic to American culture as hot dogs or apple pies. To Americans, pets are not just property, but a part of the family. After all, pets are people, too.

Gliese 581g is the sixth planet to be found circling a dwarf star some 20 light－years away

Gliese 581g is the sixth planet to be found circling a dwarf star some 20 light-years away, in the constellation of Libra. On paperit looks good – three times the mass of the Earth with possibly a rocky surface and enough gravity to hold on to an atmosphere.

The researchers also promised shirt-sleeve weatherin some regions, but not everywhere. One side of the planet is almost always in sunshine; the other almost always in darkness and estimated temperatures range from minus four degrees Celsius to a very hot 71 degrees. A year meanwhile would go by in just 37 days.

Of course, whether life could really be supported on Gliese 581g will need much more investigation and, most probably, technologies which don't exist yet. But the astronomers say planet hunting is getting easier and they were surprised how quickly they detected the tell-tale signsof this distant body, using ground-based telescopes.

21. Which of the following is correct about Gliese 581g？_____

A. It is a dwarf star with gravity.

B. It is a planet like the earth.

C. It was discovered many centuries ago.

D. It is very close to the earth.

22. What does Gliese 581g look like？_________

A. It has the mass of the sun.

B. It has about the same mass as the earth and its atmosphere.

C. Its rock and atmosphere are about three times the mass of the earth.

D. It is heavier than the earth and has a rocky surface.

23. Which of the following is correct about the gravity of Gliese 581g？________

A. It fixes the mass on.

B. It is too small to keep anything on the ground.

C. It is enough to hold on to an atmosphere.

D. It helps Gliese 581g to balance between the earth and the sun.

24. What does shirt-sleeve weather probably mean？______

A. So warm that a jacket is not needed.

B. Changeable.

C. Cold.

D. Extremely cold.

25. How was Gliese 581g found？__________

A. A scientist discovered it on the way to the moon.

B. Some scientists found it with a telescope on the shuttle.

C. It was found using telescopes on the earth.

D. It was found with the help of a computer.

If the host is doing his job, you will actually wait less than【C4】______you were told. If you are told the wait is 15 minutes and you are still waiting at the 30-minute mark, are you a happy customer？ At one level, it is just【C5】______.

Let's go back to the restaurant.【C13】______the wait is not 15minutes-it is 90 minutes. It is not what we want to hear. Still, we can decide to stay or not to stay. If we do not stay, we will be hack. But if we【C14】______told 30 minutes and it became 90, that【C15】______the last time we ate there. Sooner or later, customers al ways find out the truth. If the truth is different than what they have been told, you have lost their trust.

Truth is【C16】______accuracy. It includes a willingness to stand behind what you say. In other words, are you willing to put your money【C17】______your mouth is？ If you are working with others, part of their【C18】______is that when something goes wrong you will stand with them. If an order is delayed, for example, how will you help them【C19】______their business commitments？ Part of earning their trust is having a backup plan in place should your【C20】______systems fail.
