We are interested in the preservation of the biodiversity on Earth. What I’ve been working on is rats. Just looking at rats, you can understand continental drift and climate change. We’ve actually rediscovered rats that were thought to be extinct. Darwin was the last one to document them on the Galapagos Islands. People have gone there for hundreds of years and not seen one. In 1997, I went there with my mentor(导师) and another graduate student. Everyone thought I was crazy, why look for something that doesn’t exist? They wouldn’t even give us permits. Our plan was to stop on a beach for a day and then hike up to the top of an extinct volcano where very few people had been:We were on a picturesque, isolated beach. We set out the traps just to see what we might find. The next morning, I checked my traps! I immediately ran back to my mentor. When he looked in the mental trap—I will never forget his face--- It looked like he’d seen a ghost.
I certainly understand the argument: “ Who cares about an extinct rat?” but you have no idea what role that rat plays in that functioning ecosystem. People can appreciate beauty, so that’s why people love pandas and want to keep them around. You never hear, “What good is panda?” Ecologically, these rats are much more important to their ecosystem than those pandas--- not that I don’t love pandas but we have to look beyond the big and beautiful.
I teach conservation biology and evolution. In both you have to appeal to people asking “ Why is this important to me?” Some scientists refuse to do that. That’s my entire approach. I’ll ask “How many of you had a family member who was in a tornado, hurricane or flood?” .And almost every hand goes up. Climate change is suddenly very personal, and now they want to hear what you are saying. You are not looking for sympathy for the rats but for a greater understanding of the system.

In the long dispute over whether dogs are smarter than cats, a recent study published in the journal Learning & Behavior suggests that dogs are no more exceptional than other animals when it comes to smartness and intelligence.
The news is sure to cause the debate among dog owners and scientists who study dog behaviors. The authors reviewed existing studies and data on animal cognition (认知) and found that while dogs are smart and trainable, they are not “super smart”, despite what most dog owners will tell you. Dog research was quite popular in the 1990s and continues to be so. When it came to other animals, though, scientific studies on intelligence were barely involved in, despite evidence to suggest that horses, chimpanzees ( 黑猩猩 ) and cats had tricks of their own. Almost everything a dog claimed to do, other animals could do too.
Researchers set out to test the supposition (假设，猜想). They compared dog cognition with members of three similar groups: meat-eating animals, social hunters and farm animals. Among the animals they studied were wolves, cats, chimpanzees, dolphins, horses and pigeons. What they found was that “dog cognition does not look exceptional”. Dogs can not use tools, unlike dolphins, New Caledonian crows and chimpanzees, which have been observed using plant stems to hunt for termites (白蚁). Homing pigeons are trained to fly home, sometimes crossing hundreds of miles of unfamiliar area. At the same time, farm animals share similar characters with their dog partners. Horses, like dogs, perform complex tasks. And cats? They have more in common with dogs than one might think. Still it is much easier to show intelligence in dogs because they like to be trained. Dogs are not smarter than they are supposed to be, given what they are.
1.What opinion does the recent study hold about dogs?
A.They can be trained to do many things.
B.They don’t have any intelligent advantage.
C.They’re lazy compared with chimpanzees.
D.They show exceptional smartness when trained.
2.How did the researchers conduct the study?
A.By referring to existing studies and data.
B.By comparing animals’ cognition ability.
C.By questionnaire surveys on dog owners.
D.By observing different animals’ behaviors.
3.What do we infer about cats from the last paragraph?
A.Cats can use tools to fish.
B.Cats can go home from far away.
C.Cats can learn to do complex tasks.
D.Cats are more unwilling to be trained.
4.What is the main idea of the text?
A.Cats are smarter than they were.
B.Dogs aren’t so clever as we think.
C.Any animal is smart and trainable.
D.All animals should be treated equally.
