单选题The postal zoning system in the Unite States began in 1943 with the introduction of the one or two digit zone number. The numbers identified a delivery station of a metropolitan post office. On July 1, 1963, Mr. Zip introduced the Zone Improvement Plan. This was a five digit national coding system used to identify each postal delivery section. The first digit identifies one of ten geographical areas, with the second digit denoting a state, part of heavily populated state, or two or three less populated states. The third digit designates (指定) a major metropolitan postal facility or sectional center, with the fourth and fifth digits picking up the original zone number. The Federal German Post Office became the first to use the current postal code system to speed delivery. The function of a code system is to help in address scanning and the automated processing of mail, and to speed up mail sorting. Approximately 70 percent of all mail delivered in the United State uses the Zip Code. In 1974, the Unite States Postal Service issued a postage stamp to publicize the numerical system.

单选题As my train wasn"t due to leave for another hour, I had plenty of time to spare . After buying some newspapers to read on the journey, I made my way to the luggage office to collect the heavy suitcase I had left there three days before. There were only a few people waiting, and I took out my wallet to find the receipt for my case. The receipt didn"t seem to be where I had left it. I emptied the contents of the wallet, and railway tickets, money, scraps of paper, and photographs fell out of it; but no matter how hard I searched, the receipt was nowhere to be found. When my turn came, I explained the situation sorrowfully to the assistant. The man looked at me suspiciously as if to say that he had heard this type of story many times and asked me to describe the case. I told him that it was an old, brown-looking object no different from the many cases I could see on the shelves. The assistant then gave me a form and told me to make a list of the chief contents of the case. If they were correct, he said, I could take the case away. I tried to remember all the articles I had hurriedly packed and wrote them down as they came to me. After I had done this, I went to look among the shelves. There were hundreds of cases there and for one dreadful moment, it occurred to me that if someone had picked the receipt up, he could have easily claimed the case already. This hadn"t happened fortunately, for after a time I found the case lying on its side high up in a comer. After examining the articles inside, the assistant was soon satisfied that it was mine and told me I could take the case away. Again I took out my wallet: this time to pay. I pulled out a ten-shilling note and the "lost" receipt slipped out with it. I couldn"t help blushing and looked up at the assistant. He was nodding his head knowingly, as if to say that he had often seen this happen before too!
