How should you behave when you meet someone {#blank#}1{#/blank#}the first time? An American shakes your hand {#blank#}2{#/blank#} (firm) while looking you straight in the eye. In many parts of Asia, there is no physical contact at all. In Japan, you should bow, and the {#blank#}3{#/blank#} (much) respect you want to show, the deeper you should bow. In Thailand, people greet each other by pressing both hands together at the chest. In both countries, eye contact {#blank#}4{#/blank#}(avoid) as a sign of respect.

    In Spain, lunch is often {#blank#}5{#/blank#}biggest meal of the day, and can last two or three hours. For this reason, many people eat a light breakfast and a late dinner. In Mexico, lunch is a time {#blank#}6{#/blank#} (relax), and many people prefer not to discuss business as they eat. In Britain, it's not unusual to have a business meeting over breakfast.

    In most countries, an exchange of business cards{#blank#}7{#/blank#} (be)necessary for all introductions. You should include your company name and your position. If you are going to a country {#blank#}8{#/blank#} your language is not widely spoken, you can get the back side of your card {#blank#}9{#/blank#} (print) in the local language. In a word, when {#blank#}10{#/blank#} (travel) abroad, we should follow local habits.

    Now, I'd like to tell you about the development of computers. Computers began {#blank#}1{#/blank#} a calculating machine in France in 1642, it could {#blank#}2{#/blank#} (simple) difficult sums. In 1936, Alan Turing wrote a book about how a computer could be made to work as a "universal Machine" {#blank#}3{#/blank#} (solve) any difficult mathematical problem. By the 1940s, computers had grown as large as a room. As time went by, they were made {#blank#}4{#/blank#} (small). Since the 1970s computers {#blank#}5{#/blank#} (use) in offices and homes, first as personal computers and then as laptops.

    As computers' memory improved, computers became much smaller and more {#blank#}6{#/blank#} (intelligence). First the memory was stored in tubes, then on transistors and later on very small chips. Over time computer's memory {#blank#}7{#/blank#} (develop) so much that computers remember everything they have been told. In the early 1960s computers could be connected to each other by the network {#blank#}8{#/blank#} (call) the World Wide Web.

    Many new {#blank#}9{#/blank#} (apply) have been found for computers since the1970s. They have been used in communication, finance, trade, robots, mobile phones, space rockets and so the goal of computers is to provide humans {#blank#}10{#/blank#} a life of high quality.

    On September 11, 2001, Omar Eduardo Rivera, a blind computer technician (技术员), was working on the 71st floor of the World Trade Center with his guide dog {#blank#}1{#/blank#} (name) Dorado. When the hijacked (被劫持的) plane hit the tower, Rivera knew {#blank#}2{#/blank#} would take him a long time to escape from the building, but he wanted his lovely dog to have a chance {#blank#}3{#/blank#} (get) out so he set him free in the crowded stairwell. "I thought I was lost forever—the noise and the heat were {#blank#}4{#/blank#} (terrify) —but I had to give him the chance of escape. So I touched his head, gave him a push and ordered him to go," Rivera said.

    The dog {#blank#}5{#/blank#} (immediate) disappeared into the crowd, but a few {#blank#}6{#/blank#} (minute) later Rivera felt the dog feeling his legs. Dorado came right back to his side and a co-worker {#blank#}7{#/blank#} (bring) by him as well. Then Dorado and the selfless co-worker {#blank#}8{#/blank#} (help) Rivera climb down 70 flights of stairs, {#blank#}9{#/blank#} took nearly an hour. No sooner had they escaped from the building {#blank#}10{#/blank#} it fell down completely, and Rivera says he owes his life to his faithful dog.
