nearly ten years. Most London taxi drivers have their own taxis.”“It’s a nice job most of the time. You meet a lot of people. I always work at night, because there is too much traffic during the day. I live twenty miles outside London and I go to work at 5:30 in the afternoon.”“I usually go home between 2:00 and 3:00 in the morning.”“Some very strange things happened late at night. The other day I was taking a woman home from a party. She had her little dog with her. When we got to her house, she found that she had lost her key.

Some time later, they brought it back to see if it remembered which plate had the food. The idea is to find out how long an animal’s memory can last. The scientists would try showing the plate to the animal one hour later, or two hours later, or even a full day later. They found out that chimpanzees and elephants have the best memory, and are able to remember the correct plate for at least twenty hours. No other animal is close. Dogs e next, but they can only remember for nine hours.The scientists made a large maze(迷宮) and ran the chimpanzees and elephants through it. The maze was very difficult with many dead ends.
