 I recently heard a story about a famous scientist. Because of his great achievements, he was thought to be more creative than the common person. When he ____ (ask) why he was able to do this, he gave the answer. It all came from an experience with his mother when he was about three years old. “I____ (try) to get a bottle of milk from the fridge when I lost the bottle and it fell, spilling（溢出）the milk all over the floor—a sea of milk! I was frightened and I didn't know what to do!” he said.

 His mother heard the noise and got into the kitchen. “I____ (consider) how to explain all this to you, mom.” he said. Instead of ____ (punish) him, she said, “Robert, what a great mess you have made! I ____  (not see) such a huge sea of milk before! Well, since the milk has already been spilled, would you like ____ (play) in the milk for a while? We ____ (clean) it up after that.” Then, he did so. After a few minutes, his mother said, “You know, Robert, whenever you____ (make) a mess like this, finally you have to clean it up.” He used a sponge （海绵）and together they cleaned up the spilled milk.

 His mother then said, “You know, we ____ (fail) in how to successfully carry a big milk bottle with two tiny hands just now. Let's go out in the yard and fill the bottle with water to see if you____ (discover) a way to carry it.” Then the little boy learned that if he grasped(抓紧) the bottle at the top with both hands, he could carry it without dropping it.

 What a wonderful lesson!

    Michelin inspectors, the super secret spies of the restaurant industry, are the anonymous (匿名的) keepers of the famous Michelin star rating. They've been writing anonymous reports of restaurants for over 100 years.

    “We say it's a little like the CIA,” said inspector “M” with a laugh. She asked that her identity not be revealed. “My whole life is staying under the radar, staying away from cameras, using fake names, trying to steal in and out of restaurants quietly.”

    Along with their boss, Jean Luc Naret, the director of the Michelin Guide, about 90 inspectors around the world decide which restaurants will win the cooking equivalent (等价物) of an Oscar, the Nobel Prize and Megamillions jackpot (百万彩票) all at once. The Michelin Guide covers 23 countries, and out of the 45,000 rated restaurants, less than 100 have the top rating — only nine American restaurants carry three stars.

    If the name “Michelin” brings the tires on your car to mind, you're not too far off. The Michelin rating began in France in 1900 as a marketing trick. The Michelin brothers thought their customers would bum more rubber if given a list of hotels and restaurants to explore.

    Inspector “M” admitted being an inspector leads to a lonely dining life. “Most of the time we dine alone,” she said. “It gives us the ability to really focus on the food and the atmosphere and capture the entire experience.” To cover their tracks, “M” said sometimes two inspectors will dine together and write two separate papers. It's better than saying “table for one”, right?

    “When you're really, really into food and very crazy about food, everything else that's going on around you isn't so important,” she said.
