Do dogs understand us?
Be careful what you say around your dog．It might understand more than you think.
A border collie 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.
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 ten tests, suggesting that the dog had worked
out the answer by 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!

The first time I saw Carlos I would never have believed he was going to change my life．I had my arms full of books and I was tearing into the classroom when 1 ran into something solid．It was Carlos.
“My God, you’re tall,” he said.
Of course, the class began to laugh．Angry, I walked to my seat without a word.
I glanced back to see if Reed Harrington was laughing with the rest．That would be the last straw．But Reed was studying chemistry and did not seem to be aware of anything else．I didn’t know why I considered Reed my friend．Maybe just because he was a good two inches taller than I．Anyway, every time I blew out my birthday candles and made a wish, it was for a date with Reed Harrington.
“Take that seat，” Mr．McCarthy told the cocky newcomer Carlos，pointing to the only empty one，in the back of the room.
Carlos grinned, “But I need a couple of dictionaries.” Again the class laughed, but now they were laughing with Carlos，not at him．He had been here only 10 minutes and already he had them on his side.
It was the school elections that made me think of Carlos again．Reed Harrington was voted president and Carlos vice-president．“How come ?” I kept asking myself, “How come this shrimp who’s only been in town for a little over a month gets to be so popular?”
So that morning，I stopped Carlos and said，“It doesn’t seem to bother you — being short.” He looked up at me, “Of course I mind being short．But there isn’t anything I can do about it．When I realized I was going to have to spend my life in this undersized skin，I just decided to make the best of it and concentrate on being myself.” “You seem to get along great,” I admitted, “But what about me? Nobody wants to date a girl taller than he is.” “The trouble with you is you’re afraid to be yourself．You’re smart．And you could be pretty．In fact, you might be more than pretty.” I felt myself turning red…
