英语专业四级应试技巧：英语阅读的关键--抓主题思想(2)
<p> 三、一段文章的中心思想常常由主题句(<span word="Topic">Topic</span> <span word="Sentence">Sentence</span>)表达。主题句常常位于段首或段尾处，间或出现在段落中间。同样，一篇文章的中心思想也常常在开始或结尾段点出。因此在阅读中，我们要特别注意文章的开头或结尾。例四：</p><p> <span word="English">English</span> <span word="is">is</span> <span word="clearly">clearly</span> <span word="an">an</span> <span word="international">international</span> <span word="language">language</span>.<span word="It">It</span> <span word="is">is</span> <span word="spoken">spoken</span> <span word="by">by</span> <span word="pilots">pilots</span> <span word="and">and</span> <span word="airport">airport</span> <span word="control">control</span> <span word="operators">operators</span> <span word="on">on</span> <span word="all">all</span> <span word="the">the</span> <span word="airways">airways</span> <span word="of">of</span> <span word="the">the</span> <span word="world">world</span>.<span word="Over">Over</span> 70 <span word="percent">percent</span> <span word="of">of</span> <span word="the">the</span> <span word="worlds">worlds</span> <span word="radio">radio</span> <span word="programs">programs</span> <span word="are">are</span> <span word="in">in</span> <span word="English">English</span>.</p><p> 本段主题句为首句，其后的内容句均说明首句。例五：</p><p> <span word="Some">Some</span> <span word="students">students</span> <span word="prefer">prefer</span> <span word="a">a</span> <span word="strict">strict</span> <span word="teacher">teacher</span> <span word="who">who</span> <span word="tells">tells</span> <span word="them">them</span> <span word="exactly">exactly</span> <span word="what">what</span> <span word="to">to</span> <span word="do">do</span>.<span word="Others">Others</span> <span word="prefer">prefer</span> <span word="to">to</span> <span word="be">be</span> <span word="left">left</span> <span word="to">to</span> <span word="work">work</span> <span word="on">on</span> <span word="their">their</span> <span word="own">own</span>.<span word="Still">Still</span> <span word="others">others</span> <span word="like">like</span> <span word="a">a</span> <span word="democratic">democratic</span> <span word="discussion">discussion</span> <span word="type">type</span> <span word="of">of</span> <span word="class">class</span>.<span word="No">No</span> <span word="one">one</span> <span word="teaching">teaching</span> <span word="method">method</span> <span word="can">can</span> <span word="be">be</span> <span word="devised">devised</span> <span word="to">to</span> <span word="satisfy">satisfy</span> <span word="all">all</span> <span word="students">students</span> <span word="at">at</span> <span word="the">the</span> <span word="same">same</span> <span word="time">time</span>.</p><p> 本段中心思想在结尾句得到体现，它是此段内容的结论。例六：</p><p> <span word="For">For</span> <span word="adults">adults</span> <span word="a">a</span> <span word="cold">cold</span> <span word="is">is</span> <span word="not">not</span> <span word="that">that</span> <span word="serious">serious</span>.<span word="However">However</span>，<span word="this">this</span> <span word="is">is</span> <span word="not">not</span> <span word="the">the</span> <span word="case">case</span> <span word="for">for</span> <span word="children">children</span>.<span word="Cold">Cold</span> <span word="symptoms">symptoms</span> <span word="in">in</span> <span word="children">children</span> <span word="may">may</span> <span word="be">be</span> <span word="signs">signs</span> <span word="of">of</span> <span word="more">more</span> <span word="serious">serious</span> <span word="diseases">diseases</span> <span word="and">and</span> <span word="should">should</span> <span word="be">be</span> <span word="given">given</span> <span word="prompt">prompt</span> <span word="medical">medical</span> <span word="attention">attention</span>.</p><p> 本段主题句为第二句，因为在<span word="however">however</span>后面才是作者真正的看法，并在下文中进一步作了说明。</p><p> 然而，我们也常常发现，有的主题思想并非直接由一、二个句子表述，而是在文中间接暗示着。这就需要读者根据文中细节进行概括与归纳，找出主题思想。例七：</p>
