The Internet is an amazing information resource. Students, teachers, and researchers use it as {#blank#}1{#/blank#}investigative tool. Journalists use it to find information for stories. Doctors use it to learn more about unfamiliar diseases and the {#blank#}2{#/blank#} (late) medical development. Ordinary people use it for shopping, banking, bill-paying, and communicating with family and friends. People all over the world use it to connect with individuals from {#blank#}3{#/blank#}countries and cultures. However,{#blank#}4{#/blank#}there are many positive developments{#blank#}5{#/blank#} (associate) with the Internet, there are also certain fears and concerns.{#blank#}6{#/blank#}concern relates to a lack of control over {#blank#}7{#/blank#}appears on the Internet. With television and radio there are editors to check the accuracy or appropriateness of the content of programs, and with television there are {#blank#}8{#/blank#} (restrict) on what kinds of programs can {#blank#}9{#/blank#} (broadcast) and at what times of the day. With the Internet, parents cannot check a published guide to determine what is suitable {#blank#}10{#/blank#}their children to see.

    There are four ways {#blank#}1{#/blank#}which British and American English differ from each other. The first and most obvious way is in the vocabulary. There are a few {#blank#}2{#/blank#}(differ) in grammar, too. The British say Have you got…? {#blank#}3{#/blank#}Americans prefer Do you have…? The British use prepositions {#blank#}4{#/blank#}Americans sometimes omit them. The other two areas in which the two varieties are different are spelling and {#blank#}5{#/blank#}(pronounce). However, with communications {#blank#}6{#/blank#}(develop) {#blank#}7{#/blank#}(steady) for over a century, some experts believe that the two varieties {#blank#}8{#/blank#}(move) closer together due to satellite TV and the Internet. English {#blank#}9{#/blank#}(speak) with different accents; in the future, there are going to be many "Englishes". In spite of this, users of English will have no difficulty {#blank#}10{#/blank#}(understand) each other.

    Since 1949 when the People's Republic of China {#blank#}1{#/blank#}(establish), and especially since 1978, China's transformation from a traditional {#blank#}2{#/blank#}（agriculture）society to a modern industrial society has been greatly accelarated by a rapid industrial restructuring. China's industrial structure developed according to the objective of industrialization, {#blank#}3{#/blank#} aimed at the proportion(比例)of agriculture declining ceaselessly, and the proportion of the industrial and service sector increasing continually. {#blank#}4{#/blank#}(current), the industrial goods produced in China all range from capital goods to consumption goods.

    China's factory outputs extend from textiles (纺织业) to railway, planes and computers. China is the largest producer of inexpensive cotton textiles in the world and exports large {#blank#}5{#/blank#}(quantity) of textiles and clothes. Food processing is very important, and much farm produce is exported. Other industrial products {#blank#}6{#/blank#}(include)television sets, bicycles, cars, trucks and washing machines are expanding in the world.

    China has become {#blank#}7{#/blank#} industrialized country to some extent. The auto and the housing industry, in the process of industrialization have developed by leaps and bounds. The most important export products are machinery and electric equipment,{#blank#}8{#/blank#} the most important import products are raw materials. In recent years, China's industry{#blank#}9{#/blank#}(compete) internationally, and as a result, the {#blank#}10{#/blank#}(develop)of the country's industry is increasingly influenced by international economic environments.

The college entrance examination is just around the corner. {#blank#}1{#/blank#} (assign) and tests will keep many of you up late at night, and you may plan to make up for your{#blank#}2{#/blank#} (lose) sleep during the weekends. But is it useful?

A study shows that the habit of sleeping in{#blank#}3{#/blank#} weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}4{#/blank#} (bad), it may damage your health.

In the study, {#blank#}5{#/blank#} was conducted over 10 days, 36 healthy young men and women with different sleep requirements {#blank#}6{#/blank#} (divide) into three groups. The researchers found that people who lacked sleep ate more snacks and gained {#blank#}7{#/blank#} (weigh) quickly. That could be partially due to the shifting of the{#blank#}8{#/blank#} (biology) clock and changes to certain body hormones especially hunger hormones.

And {#blank#}9{#/blank#} they tried to sleep for as long as they wanted to on weekend, it was still insufficient(不够的) to meet standard sleep time because they found it difficult to fall asleep. Moreover, they were more likely{#blank#}10{#/blank#}(show) increased sensitivity (敏感性) to insulin(胰岛素) in both their muscles and their livers.
