Is a mouse that can speak acceptable? How about a dog with human hands or feet? Scientists, the people with the know-how to make such things happen, are now thinking about whether such experiments are morally right or not.

    On Nov. 10, Britain’s Academy of Medical Sciences launched a study on the use of animals with human materials in scientific research. The work is expected to take at least a year, but its leaders hope it will lead to guidelines for scientists in Britain and around the world on how far they can go mixing human genes into animals in search of ways to fight human diseases.

“Do these constructs (構(gòu)想) challenge our idea of what it is to be human?” asked Martin Bobrow, a professor of medical genetics at Cambridge University and chair of a 14-member group looking into the issue. “It is important that we consider these questions now so that appropriate boundaries are recognized.”     

Using human material in animals is not new. Scientists have already created monkeys that have a human form of the Huntingdon’s gene so they can study how the disease develops; and mice with livers (肝) made from human cells are being used to study the effects of new drugs.

However, scientists say the technology to put ever greater amounts of human genetic material into animals is spreading quickly around the world --- raising the possibility that some scientists in some places may want to go further than is morally acceptable.

     Last year in Britain there was a lively debate over new laws allowing the creation of human-animal embryos (胚胎) for experiments. On one side of the debate were religious groups, who claimed that such science interferes with nature. Opposing them were scientists who pointed out that such experiments were vital to research cures for diseases.

The experts will publish reports after the end of the study, in which they will give definitions (定義) for animal embryos with human genes or cells, look at safety and animal welfare issues, and consider the right legal framework to work within. 

72. What does the underlined word “they” in Paragraph 2 refer to?

   A. Scientists in Britain and around the world.           

B. Leaders of the research.

   C. Guidelines for scientists.                         

D. Scientific experiments.

73. Scientists do research of mixing human genes into animals in order to ____.

   A. test new drugs on animals

   B. to find ways to fight human diseases

   C. prove the research is morally acceptable

   D. create monkeys and mice with livers made from human cells

74. We can infer from the passage that ____.

   A. the experts will release reports after the study

   B. scientists have never doubted the use of animals with human materials

   C. the creation of human-animal embryos for experiments is legal in Britain

   D. religious groups hold that cures for diseases have to be done through experiments

75. What would be the best title of the passage?

A. Morally right or not?                                   B. A debate about new laws

C. Cures for diseases                      D. Animal embryos with human genes

If you have mice in your house, you’re not alone. Having mice doesn’t mean your house is dirty. It is one of the challenges of every house owner.

  When we are trying to catch a mouse, the first thing that comes to our mind is a mouse trap. Mice travel along walls for safety. Don’t touch the trap too much because you will leave your smell on it.

 Usually, mice will not visit your house when they hear there is a cat inside. It will also help you fight against the mice.

  Be careful when using poison (毒藥) to kill the mice. It is dangerous because they may touch your food and pollute it.

  Mice can get into the houses through tiny holes. The best way to have a mouse-free house is to close any possible entry(入口).

If there is nothing there for them to eat, they won’t possibly stay.

A. Keep a cat as a pet in your house

B. Cheese is the favorite food of mice.

C. Every house may have mice for some reason.

D. Leave the poison out of your children’s reach.

A mouse looked through a hole in the wall to see the farmer and his wife opening a package. What food might it contain? He was astonished to discover that it was a mouse trap!
　　Running to the farmyard, the mouse shouted, warning, “There is a mouse trap in the house; there is a mouse trap in the house.” The chicken with her head high, said, “Shut up, Little Ugly. This is a great concern to you, but it has nothing to do with me; I cannot be bothered by it.”
The mouse turned to the pig and told him, “There is a mouse trap in the house.” “I am so very sorry, Mr. Mouse,” said the pig, “but there is nothing I can do about it but pray; you are always  in my prayers.”
　　The mouse turned to the cow, who said, “A mouse trap; am I in great danger, huh?”
So the mouse had to face the farmer’s mouse trap alone.
　　That very night a sound was heard through the house, like the sound of a mouse trap catching its prey. The farmer’s wife rushed to see what was caught. In the darkness, she did not see that it was a poisonous snake whose tail the trap had caught. The snake bit the farmer’s wife. The farmer rushed her to the hospital.
She returned home with a fever. It is said that drinking fresh chicken soup will help treat fever, so the farmer took his sharp knife to the farmyard for the soup’s main ingredient. His wife’s sickness continued so that friends and neighbors came to sit with her around the clock. To feed them, the farmer killed the pig. 　　The farmer’s wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow killed to provide meat for all of them to eat.
So next time someone is facing a problem, don’t say that has nothing to do with you.

A mouse looked through a crack(縫隙) in the wall to see the farmer and his wife opening a package; what food might it contain? He was astonished to discover that it was a mouse trap!
Running to the farmyard, the mouse shouted, warning everyone, “There is a mouse trap in the house, there is a mouse trap in the house.”
The chicken, with her head high, glared at the mouse and said, “Shut up. Little Ugly. This is a great concern to you, but it has nothing to do with me; I can’t be troubled by it.
The mouse turned to the pig and told him, “There is a mouse trap in the house.” “I am so sorry, Mr. Mouse,” said the pig sympathetically, “but there is nothing I can do about it but pray; you are always in my prayers.”
The mouse turned to the cow, who relied, “ A mouse trap, am I in great danger, huh?”
Now the mouse had to face the farmer’s mouse trap alone.
The very night a sound was heard through the house, like that of a mouse trap catching its prey. The farmer’s wife rushed to see what was caught.
