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(碳足迹) 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(可持续的) 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(公顷), 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(仓鼠) 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 medium-sized dog eats around 95 kilos of grain and meat a year
B．a 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 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．

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(信号). 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.

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!
Animals can help people, too. Dogs can be taught to become the “eyes” for a blind person or “ears” for a deaf people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, animals are brought into hospitals for “visit”.
Americans hold “Be---Kind-to-Animals Week” in the first week of May. Pets shows are held during the week. Even if you don’t live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.
f you don’t have a pet, be kind to animals around you. For example, if you see a street dog, don’t kick it or throw things at it. Instead, just leave it alone, or better yet, make friends with it. If others around you do bad things to an animal, try to stop them. As people, we must protect animals who can’t speak for themselves.
