    We see them everywhere — on boxes of food, on packages and on CDs. They, of course, are bar codes. The invention of bar codes has changed the way we shop and how companies learn where their products are.

    It was two university students from America, Bernard Silver and Norman Woodland, who first got theidea of bar codes. In 1948, they heard that the president of a food company was looking for a way to easily get information about what was being sold to customers. They tried to help by using a code system. They invented a large electronic reader to read the codes. However, computers couldn’t easily record the data that was read.

    Then, in the 1960s, David Collins made important developments in bar codes. He developed a system for recognizing train carriages. In order to develop the recognition system for other kinds of businesses, Collins started his own company. In 1969, Collins’s company put a bar code reading system in a car factory, showing that bar codes could be useful.

    Shortly after Collins started his company, an American electronic company called RCA also saw the potential (潜力) of bar codes to help businesses. RCA’s

    system, which recorded how much of a product was sold, was not perfect. Since bar codes were not common, not all products had them and different companies used different codes. Then, Woodland helped develop the Universal Product Code (UPC), which gave every product a code that included information about the manufacturer and the kind of product being sold. This made bar codes much more practical.

    In addition to shops, hospitals use bar codes to recognize patients by giving them cards with bar codes on them. Libraries use bar codes to record which books have been lent, and airports use them to find out where bags are going. Bar codes have made life much easier and simpler.

    【题目】

    Learning vocabulary doesn’t have to be boring

    Many students have problems with vocabulary when preparing for tests like the SATs. Last week, TEENS offered advice on how to memorize new words. If you’re now familiar with those methods, why not try moving on to the next stage by using the following tips to build up your English vocabulary.

    Repeated encounters (反复遇见)

    The usual way of “memorizing” new material is through repeating it while it’s still in your mind. However, simply repeating a word seems to have little long-term effect.

    But one kind of repetition is effective: repetition of encounters with a word. Words stand a good chance of being remembered if they’ve been met at least seven times in your reading, at intervals (相隔一段时间). So, read English magazines, newspapers, and websites regularly.

    Spacing and review

    It’s better to distribute (分配) memory work over a period of time rather than do it in a single session (一段时间). This is known as the “principle of distributed practice”, where new vocabulary introduced in one lesson is reviewed in the next, and then in later lessons.

    Use it or lose it

    Putting words to use in interesting ways helps add them to your long-term memory. In a study of vocabulary learning, students who made up their own sentences with new words and read them aloud remembered them better than those who learned the words separately and silently. Best of all, students were given the task of silently imagining a picture in their minds to go with a new word. So it might help if learners link words with a mental image.

    Mix it up

    Let’s face it — learning words can be really boring, but it doesn’t have to be. Thanks to the Internet, there are more interesting ways to get the job done. Try watching videos from English-speaking social media celebrities and copying the way they speak. You could even upload your own videos and try becoming a star yourself.

    【1】According to the passage, a good way of memorizing new words is ________.

    A. simply repeating them

    B. learning the words silently

    C. reviewing them in one lesson

    D. reading English magazines regularly

    【2】To make learning words more interesting, we can ________.

    A. try to become a famous star

    B. read new words on websites

    C. make and upload our own English videos

    D. draw a picture on the paper with a new word

    【3】What does the passage mainly talk about?

    A. Where to use new words. B. How to memorize new words.

    C. When to learn new words. D. What to write with new words.

    【题目】

    In Britain, people often invite friends for a meal, a party or just coffee. People who know each other very well close【1】, family or neighbors visit each other’s houses without an invitation (邀请), but usually an invitation is needed．【2】people invite someone to their homes, they often say: “Would you like【3】for dinner on Saturday?” Answers are: “Thanks. We’d love to. What time?” or “I’m sorry. We’d love to but we have tickets【4】the concert.” However,【5】is not polite to say “No, we wouldn’t!”

    Sometimes, the British use expressions (表达) that sound like invitations but which are not invitations. For example: “You must come over for【6】drink sometime.” or “Let’s go out for a meal one of these days.” These are usually just polite【7】of ending a talk. They are not real invitations【8】they don’t mention an exact time or day. They just show that the person is【9】

    to be friendly and the answers are: “Yes, that would be nice.” or “OK, yes, thanks.”

    So next time you hear what sounds like an invitation, listen【10】. Is it a real invitation or is the person just being friendly?
