Samuel Morse and I, Alfred Vail, sat in our workshop. We were studying how to turn dots (•) and dashes (—) into a message. Morse's first idea was to tap out numbers—one tap for "1", a long tap and two short ones for "12", and so on. Then he made a big list of words and gave their numbers—"342" meant "train" and so on. But I wasn't so sure this was the best way. His word book was huge. It would take hours to look up codes (代码). Too slow! "Why couldn't the dots and dashes stand for letters instead?" I shared my better idea. "How could that work?" Morse asked. "Well, for example, two dots could be 'D' instead of '2'. There are only 26 letters—why not give each one a dot-and-dash code? That way, words could be tapped out directly, letter by letter. Imagine the time saved!" Morse snorted (哼了一声), really unhappy after all of his work on the word list. Just to try it, I wrote down the letters and gave each letter a tap code. Then I tapped out a message, and Morse deciphered (破译) it. Quickly! He read out my message: "To tell the truth, I think this saves much time." He nodded. "Yes, I see your point. Not bad." But I'd noticed something else about our code. "That message had a lot of Ts," I said. "The code for a T is a dash-dash dot... I'll bet I could have done that even faster if T didn't take so long to tap." Ten minutes later I was in the local newspaper office. With the help of a printer, I was soon back with a list of letters in order of how often they are used in English. "Let it be so! It makes good sense to use the shortest codes for the most common letters. I see E is the favourite, so a single dot for E and a dash for T. To start, a dot-dash for A," Morse said, patting me heartily on the back. "You impress me! Vail, you're a genius (天才)." I smiled. I wouldn't say so out loud, but I had to agree with him. 1.In Morse Code, the word "TEA" should be ____. A. — • • — B. • • — — C. • — — • D. • — • — 2.From the story, we can learn that Vail was ____. A. practical and loyal B. organized but proud C. confident and creative D. careful but doubtful 3.Which can be the best title for the story? A. The father of Morse Code B. The small secret of Morse Code C. Always follow your dreams D. Two heads are better than one 六、信息还原 Imagine you are walking through deep snow. 1 . That's what happens when using technology, such as computers, mobile phones and tablets. You leave your digital (电子的) footprints and they will never disappear. Here are the reasons why your digital footprints should matter to you. How people see you Of course, you have nothing to hide, but if people get information about you, they might describe you from what you have left online. 2 . Years later, it's found by the university you want to enter, and they don't think it's funny. Maybe they decide you are not the "right" kind of person for them. Your private information 3 . For example, you might share your school reports with your parents, but you'd better keep them secret to your e-friends. If you share them on the Internet, they will not be a secret anymore. Therefore, to protect your privacy (隐私), remember to put less information online. 4 There are plenty of people looking at information about you, and some of them want to steal money from you. So you shouldn't write bank details, card numbers or passwords in emails or text messages. Overall, the message is: 5 —but with care, you can control it. A. Keeping your money safe B. For example, you make a bad joke online C. Not everything can be shared with everyone D. Remembering your card numbers or passwords E. As you walk, you leave footprints where you've been F. No one can go online without leaving his digital footprints G.
