Man’s best friend could be one of the environment’s worst enemies, according to a new study that says that your pet dog’s carbon pawprint(碳足跡) is more than double that of a sports car.

         Yet this point of view, made by New Zealanders Robert and Brenda Vale, has angered pet owners who feel they are being picked out as troublemakers.

         The Vales, researchers in sustainable(可持續(xù)的) living, looked at popular brands of pet food and calculated that a medium-sized dog eats about 164 kilos of meat and 95 kilos of grain a year.

         Combining that with the energy needed to produce that food, it means a medium-sized dog has an annual footprint of 0.84 hectares(公頃), about twice the 0.41 hectares required by a sports car driving 10,000 kilometers a year, including energy to build the car.

         “Owning a dog really is quite an extravagance(奢侈), mainly because of the carbon footprint of mean. Other animals aren’t better for the environment,” the Vales say.

         Cats have an eco-footprint of about 0.15 hectares a year, while two hamsters(倉(cāng)鼠) are the same as a television and even the goldfish burns energy equal to two cellphones.

         However, Reha Huttin, president of France’s 30 Million Friends animal rights foundation says pets are too important to human life to be got rid of.

         “Everyone should work out their own environmental effect,” Huttin argude. “I should be allowed to say that I walk instead of using my car and that I don’t eat meat, so why souldn’t I be allowed to have a little cat to reduce my loneliness?”

         The Vales give some solutions to reduce pets’ environmental effect, including reducing pets’ meat intake. But they said that, as with buying a car ,humans should take the environmental effect of their future compainon into account.

71．The best title of the article is "______"．

         A．Work out our carbon emissions         B．Reduce our pets’ meat intake

         C．Be careful of keeping our pets          D．Mind our pets’ carbon footprint

72．Reha Huttin’s remark really means that ______．

         A．pets should not be kept as a result of consuming much food

         B pets are doing no harm to the environment at all

         C．people can keep pets by reducing their environmental effect

         D．he prefers walking to driving to reduce his loneliness

73．We know from the article that ______．

         A．a(chǎn) medium-sized dog eats around 95 kilos of grain and meat a year

         B．a(chǎn) medium-sized dog has an annual footprint 5．6 times that of a cat

         C．two hamsters burn the same energy as two televisions

         D．a(chǎn) sports car running 10,000 kilometers requires 0.41 hectares of footprint

74．Which of the following is NOT true according to the article?

         A．The Vales insist that pets should be got rid of．

         B．Some pet owners are against the Vales’ point of view．

         C．Keeping pets does have a bad effect on the environment．

         D．Pets’ carbon footprint should not be neglected．

75．Which of the following can help reduce pets’ environmental effect based on the text?

         A．Feeding pets on less meat．

       B．Working out eco-footprints of pets．

         C．Keeping the goldfish instead of dogs．

         D．Getting rid of pets from human life．

A farmer had some puppies he needed to sell. He painted a sign advertising the pups and set about nailing it to a post on the edge of his yard. As he was driving the last nail into the post, he felt a tug on his overalls. He looked down into the sad eyes of a little boy.

“Mister," he said, "I want to buy one of your puppies." 

"Well," said the farmer, as he rubbed the sweat of the back of his neck, “these puppies come from fine parents and cost a good deal of money."

The boy dropped his head for a moment. Then reaching deep into his pocket, he pulled out a handful of change and held it up to the farmer. "I've got thirty- nine cents. Is that enough to take a look?”  

"Sure," said the farmer.

And with that he let out a whistle. "Here, Dolly!" he called.

Out from the doghouse and down the ramp ran Dolly followed by four little balls of fur. The little boy pressed his face against the chain link fence. His eyes danced with delight.

As the dogs made their way to the fence, the little boy noticed something else stirring inside the doghouse. Slowly another little ball appeared; this one noticeably smaller.

Down the ramp it slid. Then in a somewhat awkward manner, the little pup began hobbling toward the others, doing its best to catch up....

"I want that one," the little boy said, pointing to the runt.

The farmer knelt down at the boy's side and said, "Son, you don't want that puppy. He will never be able to run and play with you like these other dogs would."

With that the little boy stepped back from the fence, reached down, and began rolling up one leg of his trousers. In doing so he revealed a steel brace running down both sides of his leg attaching itself to a specially made shoe. Looking back up at the farmer, he said, "You see sir, I don't run too well myself, and he will need someone who understands."

With tears in his eyes, the farmer reached down and picked up the little pup. Holding it carefully he handed it to the little boy.

"How much?" asked the little boy.

"No charge," answered the farmer, "There's no charge for love."

The world is full of people who need someone who understands. It's National Friendship Week.

How many baby pups did the farmer have for sale?

  A. 3                                B. 4                             C. 5                             D. 6

Why did the farmer agree to sell the boy one of the puppies?

  A. The boy had the money to buy one.   

  B. There were few people wanting to buy a dog.

  C. The farmer felt sorry for the boy.             

  D. The farmer wanted to get rid of the dogs quickly.

Which of the following words is closest in meaning to the underlined word “ hobbling”?

  A. strolling.                     B. crawling.                       C. limping.                 D. running.

Why did the boy finally choose the “ hobbling” pup?

  A. He feared the farmer would kill it.           

  B. He thought no one else would buy that pup.

  C. He believed it was the cutest of the pups.          

D. He could identify with this pup.

What would be the most suitable title for this passage?

  A. Man’s Best Friend                                        B. Puppy For Sale.       

  C. Perfect Match.                                                 D. Love at First Sight.

Everybody hates rats(老鼠). But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.
What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal(信號(hào)). This is sent to a small radio on its back and then the rescuers follow the radio signals. When rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “Robots’ noses don’t work well when there are other smells around. Rats are good at that. ” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe. ” Perhaps for the first time in history, people will be happy to see a rat in a building, but only after an earthquake, of course.
【小題1】 In the world earthquake capitals, rats will become man’s best friends because they can ______.

A．take the place of man’s rescue jobs
B．find the position of people alive who are trapped in buildings
C．serve as food for people alive who are trapped in buildings
D．get into small spaces
【小題2】From the third paragraph we know the rescuers can judge a person is alive by ______.
A．the noise made by the rat
B．the rat’s unusual behavior
C．the signal sent by the radio on the rat’s back
D．the smell given off by the person
【小題3】In doing rescue jobs, ______.
A．rats smell better than dogs
B．dogs don’t need to be trained to smell people
C．robots’ sense of smell can be affected by other smells around
D．rats can see in the dark and they are smaller than robots

A．they are more fantastic than other animals
B．they are less expensive to train than dogs

In America, when people say “man’s best friend”, they don’t mean another person. Instead, they are talking about a lovely animal：A dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people’s lives. Some people regard their pets as their children. A few even leave all their money to their pets when they die!
