In many stories on TV and in science-fiction books, men travel to faraway stars. They have quick, easy journeys. But so far, men have been able to reach only the earth’s own moon.Suppose a man wanted to reach a distant star. Even if he traveled his whole life, he would have to move faster than the speed of the light. Nothing can move that fast except light itself.Strange things happen to an object when it moves rapidly. The object weighs more. An object moving at 86 percent of the speed of light is twice as heavy as it is at rest. A stick appears shorter. A clock runs more slowly. A man would not age so fast as he would on the earth.Light travels more than 186,000 miles a second, or about 11 million miles a minute. In one year, light travels six trillion miles. That great distance is called a light-year. It is used to measure distance in space.The star closest to our sun is Alpha Centauri. It is more than four light-years away. If one traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But, even at that speed, he could not reach Alcaid (北斗星) in the handle of the Big Dipper. A one-way journey to Alcaid would take almost 200 years1.In this passage the words “closest to our sun” means the star().A、the earth we live onB、Alpha CentauriC、the Big DipperD、the moon2.A one-way journey to Alcaid would take().A、about nine yearsB、less than four yearsC、almost 200 yearsD、less than 100 years3.Why do we measure the distance in light-years instead of miles?()A、Units of light-years sound better.B、Using light- years reduced the number of figures used.C、We used to measure distance in light-years long ago.D、We do not make mistakes when we use light-years.4.If a stone moved at the speed of light, it().A、would weigh twice more than it is motionlessB、would weigh as much as it is on earthC、would weigh less than it is on earthD、would not have weight at all5.This story is mainly about ().A、the distance between the sun and the other starsB、the problems of traveling to faraway starsC、what happens when we travel faster than the speed of lightD、the tool we use when we go to faraway stars

Why do Westerners love their pets so much, almost as if they were their children? I su
Why do Westerners love their pets so much, almost as if they were their children? I suppose one reason is that for more than one hundred years many children's books in England and in America were animal stories.By this we mean stories that gave the animals human names, human voices, human emotions, and even faces that look almost human.Many of these stories taught a moral lesson, like honesty or kindness or hard work.My mother read animal stories to me as a child, and my wife and I read some of the same animal stories to my boys when they were small, and now they read animal stories to their children.Some are the same stories about dogs and cats and rabbits and horses.So children in America grow up with good feelings toward animals. Many families would like to have a purebred dog or cat, that is an animal whose parents come from a single kind of animal.But purebred animals are expensive.And those that are registered with a special dog or cat club are even more expensive since there is a written record of their ancestors for many generations.What often happens is that a family's first pet will come from some friend whose pet has had babies.Or they may get a pet from an animal shelter.Every city and many smaller towns have a humane society which cares for animals that are found and for animals which people no longer want.They try to find the owner of lost pets and to find homes for the others.Over the years my wife and I and our children have gotten some very nice dogs for our family from animal shelters, usually at no cost.

But some families do not want a house dog or a house cat.They want an outside dog or cat.So the animal stays outsides the house most of the time.Special dog houses are made for such dogs to use, especially at night in the colder parts of North America.

1.Why do Western people love their pets so much? ()

A.Because their children don't have many friends.

B.Because they have leisure time and enough money.

C.Because they are influenced by animal stories.

D.Because they regard pets as their children.

3.A purebred dog refers to a dog()

A.which is brought up by one family

B.whose parents come from the same area

C.whose parents belong to the single kind of dog

D.which is bred in a pure house

4.How do most Americans get their first pet? ()

A.They buy it from a pet shop

B.They pick up one from the street

C.They always get one from the animal shelter

D.They get it from their friends

5.Not all pets stay with their masters in the house all the time for().

A.it's good for them to stay outside

B.people think they are dirty

C.Some people don't want a house dog or a house cat

D.they don't like to stay in their masters' house
