As early as 2005, there were a number of new stories about dog cloning(克隆) and cat cloning. Animal cloning had been old news for nearly a decade by then, with the revolutionary (革命的) cloning of Dolly the sheep in Scotland.
However, Snuppy was the first pet, a dog, to be cloned. Since the cloning of Snuppy, there has been some very successful cloning of pets and other animals. Lou Hawthorne started BioArts while cloning his beloved mixed-breed dog Missy. Hawthorne was very pleased with the results of the cloning, producing three successful clones that were very alike to the original in character and behavior. In January, 2009, a Florida couple, Ed and Nina Otto, announced that they had paid to have their dog cloned by BioArts.
All new technology is overpriced. For example, personal computers were not very affordable at first. Only after the producing process was improved was it possible for every family to have a computer. How much room there will be for organizations to reduce the price point on pet cloning without broad demand is of course questionable.
There are many great dogs and cats that can be found at the local dog pound ( 野狗收容所) or are given away for “free to good homes” in classified ads (分类广告). However, there is no limit to the value people place on a beloved pet. The Ottos are a good example of that. If people can buy a dog or cat with predictable behavior and characteristics, there is value in that. There is a predictable market here, though it may always be limited in size.
While pet cloning has not taken off as some hoped, it’s clear that it will become a bigger market in the future and it will be increasingly possible for people to try this out. With the inevitable (不可避免的) success that cloned pet owners will have, the practice will become more widely accepted and it seems inevitable that there is a future for cloned dogs and cats.
1.What is the main idea of this passage?
A. The brief introduction of pet cloning. B. The behavior of cloned animals.
C. The cases of pet cloning. D. The history of pet cloning.
2.What can be inferred from the passage?
A. Pet cloning will be accepted by everyone.
B. New technology of pet cloning will be invented.
C. Human cloning may one day become a reality.
D. The price of pet cloning may not be cheap.
3.Which of the following has the closest meaning to the underlined word in the third paragraph?
A. cheap B. wonderful
C. expensive D. various
4.What does the author think of the market of pet cloning?
A. Negative B. Not clear
C. Indifferent D. Optimistic

Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. Americans won’t live without cars!
Most Americans would find it hard to think what life would look like without cars. However, some have realized the serious problems of the air pollution that is caused by the car.
The polluted air becomes poisonous and dangerous to health.
One way to get rid of the polluted air is to build a car that does not pollute. That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.
Another way is to take the place of the car engine by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.
To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean.
But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.
Although cars have led us to a better life, they have also brought us new problems.
1.How many ways to get rid of air pollution are suggested in this article by the writer?
A. Four. B. Three.
C. Two. D. One.
2.If the number of cars is cut down, the most serious problem to American workers is_______.
A. to have no work to do B. to keep the air clean
C. to get a better life D. to go to work by bike
3.What is the conclusion(结论) of the writer?
A. Bicycling is the only way out.
B. The number of cars must be cut down.
C. Cars bring us nothing but serious problems.
D. Cars bring us not only a better life but serious problems.
4.To reduce pollution, we’ll have to make some changes in the way many of us live, EXCEPT that ______.
A. Americans have to cut down on the number of their total cars.
B. People are encouraged to travel and go to work by bicycle.
C. The number of cars on the roads should be limited every day.
D. People should build more roads and fill cars and trucks with gas.
