It was my birthday last Thursday. I decided to celebrate by inviting a few friends out to supper.I chose a restaurant in a quiet part of town. It is one of my favourite restaurants because the food is good and the waiters are friendly. 1.so it is not usually necessary to book a table. In any case, Thursday is not a busy evening as before.
2.. I looked around but no table was free. One of the waiters recognized me. He came across and explained the situation. “A party of tourists came in about half an hour ago，”he said. “It was like an invasion(侵略) .Suddenly the place was full! We can hardly manage(对付，应付) .”
The waiter then pointed to a table in the corner. “The people there are about to leave.” he said. “Just hold on and you'll find a place there.” He was right. Fifteen minutes later, the people at the corner table paid their bill, got up and left. I led my friends across and we all sat down.
3.. We tried to call the attention of the waiter who sent us there， but he， like all the other waiters， was busy with the party of tourists. They ordered lots of food. At last， an hour later， the tourists were finishing their meal and looking very satisfied with life. The waiter， now very tired， appeared at our table. 4.
A few moments later he returned to our table. We could tell from his face that he had bad news for us. 5. “All we can offer you, ”he said，“is an omelet(煎蛋卷) !”

Monkeys seem to have a way with numbers.
A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols made up of numbers and selective letters with 0-25 drops of water or juice as a reward. The researchers then tested how the monkeys combined—or added—the symbols to get the reward.
Here's how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.
After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, showing that they were performing a calculation(计算), not just remembering the value of each combination.
When the team studied the results of the experiment more closely, they noticed that the monkeys tended to underestimate(低估)a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction(小部分)of the smaller number to it.
"This shows that there is a certain way number is represented in their brains, "Dr. Livingstone says. “But in this experiment what they're doing is paying more attention to the big number than the little one.”
