Do dogs understand us?
Be careful what you say around your dog. It might understand more than you think.
A border collie博德牧羊犬 named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by the process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.
Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

Catherine Destivelle is a rock star. She loves rock, but she can’t sing or play the guitar! She is a rock climber and a big star in France and Italy. She is the most famous woman climber in the world because she often climbs without ropes. She climbs in many countries but most often in the French Alps near Chamonix, where she lives. She started climbing near her home in Paris when she was five. Then, at fourteen, she joined the French Alpine Club to learn more, but immediately she climbed better and more quickly than the older members of the club. She won her first competition in Italy in 1995.
Three years ago she found a new route up the Dru Mountain near Chamonix. The climb took eleven days and for four days the snow was so heavy that she could not move. Last year other climbers tried to follow the new Destivelle Route, but they failed. They are going to try again this year.
People always ask her about her climbing. She says, “I climb because I’m in love with mountains. I like touching the rock and reading the face of the rock. I like it a lot. I felt at home on the side of a mountain. I prepare well before I go, so I’m never worried.”
Catherine chooses new mountains from books—like buying from a shopping catalogue(目录)! “I see a nice mountain and I go to climb it!” Her next mountain is in Pakistan. She is going there next month. “It’s much bigger than the Dru, so it’s going to take longer to climb. An American climber, Jeff Lowe, is coming with me to help.”
