Go ahead，talk to your dog.
As many a dog owner will prove, our furry friends are listening. Now, for the doubters, there is scientific proof that they understand much of what they hear. A border collie called Rico can fetch at least 200 objects by name， researchers in Germany say. The dog also appears to learn words for new objects as easily as a 3-year-old child would. Its word-learning skill is as good as that of a parrot or chimpanzee.
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them randomly into 20 sets of 10 objects each. The dog waited with one of his owners in one room, while an experimenter put a set of 10 objects into another room. Then, the owner told the dog to fetch one of the items. The dog had to go to the other room and bring the object back.
In four trials, Rico got 37 out of 40 commands right. Because the dog couldn't see anyone to get visual clues about what to bring back, the scientists concluded that he 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 he already knew. The dog's owner then told him to fetch the object, using a word Rico had never heard.
In 7 out of 10 trials, Rico picked the right object, suggesting that he figured out the answer by process of elimination. A month later, he remembered half of the new names, which further impressed the researchers.
Rico is probably smarter than the average dog, the scientists say. For one thing, he's a border collie, a breed known for its mental abilities. In addition, the 9-year-old dog has been trained to retrieve toys by their names since he was 9 months old.
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 pup every now and then. You might just get a big, wet kiss in return!

At the end of my senior year of high school, I got a job working at a local coffee shop. I thought the job would be easy and stress-free. I   1   myself pouring the best coffees, making delicious doughnut （炸面包圈）, and becoming friends with   2   customers.

       But I wasn't   3    the people with enormous orders, the women who   4  that the coffee was much too creamy （全乳脂的）, or the men who wanted their iced coffees   5  again and again until they reached perfection. I couldn't seem to   6 anyone.

       One rainy day, one of my regular customers came in looking  7  . He said he felt like getting in bed, pulling the   8  up over his head, and staying there for a few years. I knew exactly how he felt.

      9   he left, I handed him a bag along with his iced coffee. He was   10  , since he hadn’t ordered anything but coffee, I had given him his favorite type of doughnut.

“It’s   11  me,” I told him. “have a nice day.”

He smiled and thanked me before heading back out into the  12  .

The next day, it was still raining. I   13  my afternoon hanging out the window, handing people their  14   . I was completely wet and freezing cold.   15  , no one was tipping that day. Every time I looked into our   16   tip jar, I grew more depressed.

In the evening, the customer from the day before drove up to the window. He handed me a pink rose and a  17 ．He said that not many people took time to  18  others and he was glad there were still people like me in the world．With a friendly wave, he drove away．I ran to the back of the shop and read the note．It read: Christine,

       Thanks for being so sweet, kind and thoughtful yesterday．It's so nice to meet someone who’s genuinely （真诚地） nice．Please don ' t change your   19  ! Have a great day !——Hank

       After that, whenever I felt depressed or sick of coffee, I thought of Hank and his kindness．Then I would smile, hold my head up high,   20   my throat and ask politely, "How can I help you?"
