On the morning of November 18, 1755, an earthquake shock Boston． John Winthrop, a professor at Harvard College, felt the quake and awoke. “I rose”, Winthrop wrote, “and lighted a candle, looked at my watch, and found it to be 15minutes after four.” John Winthrop hurried downstairs to the grandfather clock．It had stopped three minutes before, at 4:12．Except for stopping the clock, the quake had only thrown a key from the mantel（壁炉台）to the floor．

The clock had stopped because Winthrop had put some long glass tubes he was using for an experiment into the case for safekeeping． The quake had knocked the tubes over and blocked the pendulum（钟摆）．Winthrop, therefore, had the key on the floor． The quake had thrown it forward in the direction of the quake’s motion by a shock coming from the northwest, perhaps in Canada．

“I find myself glancing at my watch to see how long I’ve been standing in line,” she said. “Everywhere I go, I notice if the dumpster(垃圾罐)gates are open or if there’s trash in the parking lot.” Ms. Clark is a “mystery shopper”, one of thousands of contract workers that companies hire to pretend as regular customers in order to judge customer service, cleanliness and whether a store is selling a product that meets company specifications (规格).
Mystery shoppers can be found or, rather, not found, everywhere from restaurants and automotive shops to convenience stores and department stores. They play a constant cat-and-mouse game with store and restaurant employees and managers. However it’s not all fun and games. Once in the field, a mystery shopper will typically visit several stores or restaurants per hour, taking mental notes while inside, then jotting down physical notes after they leave.
It’s important for mystery shoppers to be as exact as possible, because the client companies are looking for data they can use to improve their service. The questionnaire won’t say, “Does the trash can need to be emptied?” What an educated shopper will say is, “The trash can to the left of the front door was overflowing with 10 pieces of trash on the ground.” Companies don’t need opinion but facts.
Nowadays mystery shoppers are armed with a number of high-tech devices, such as a digital scale and a digital thermometer, as well as a handheld PC for recording the entire experience. It’s a challenging job but a rewarding one. Mystery shoppers can be full time or part time, but the full-time workers tend to stick to standard mystery shopping while part-timers often choose the less complex reward-based programs. In those , the shoppers stay disguised(装扮的) only until the “shop” is finished, and then reveal (透漏) themselves to the store management and award prizes to employees who provided excellent service.
To be a mystery shopper, it’s important to be a good observer, but sometimes it’s important to have the right profile(外表), too. Companies often hire shoppers from particular backgrounds to better blend in with clients’ regular customers. If a secret shopper will be sent in, for example, to do a high-end automotive shop, the candidate must have a particular profile that meets a high-end, luxury car-type buyer profile. “It’s a challenge to perform your shop without being discovered,” Ms. Clark said, “because most of the people that we work for are very aware of the mystery shopping program.”

In life, people come across many experiences, which they remember throughout their lives. I had a similar experience, too.
I was very excited. It was the day of my last paper of the final examination. My mind was full of thoughts of how I would spend my vacation. I was especially excited of the invitation that my uncle had given me to stay with him for a few days in Cambridge.
I was prepared for the subject, physics. My friends and I were on the ground doing the last minute revisions and also discussing the questions that were supposed to come in the paper. Suddenly the bell rang and we got into our classrooms. The teacher came and quickly handed out the answer paper and the question paper. The paper was of two hours and some of the expected questions came. I finished it almost forty-five minutes earlier. But since it was a rule not to collect the answer paper before the allotted（规定的）time. the teacher was not collecting and I had to sit till the time was over. I checked my paper twice and corrected some of the mistakes in it. I started thinking about the place my friends and I had planned to go after the paper.
Though I was thinking for a long time, the time seemed to be endless. So I thought of drawing something on the question paper and turned it overleaf. I was shocked to see that the page which I had supposed to be blank had four more questions on it which carried 20 marks and would take at least half an hour to complete. I had a quick glance at my watch. There were only 10 minutes left. I was so nervous that I was hardly in a state to write anything. They were the sub-questions（小题）of the last question. Suddenly our physics teacher came in and told all of us that in the last question, out of 6 sub-questions only 2 had to be solved. I felt very much relieved.
Thereafter I never made such mistakes again. But I realized that my anxiousness and excitement could have cost me to lose 20 marks and decided never to make such a mistake again.
