根据语境猜测生词或短语的意思，或者推断熟词生义，是考生必须掌握的一项重要阅读技能，因此，词义猜测题是高考阅读理解的必考题型。这类题包括猜测单词、短语、句子的意思和判断指代内容。题干中通常含有<span word="mean">mean</span>，<span word="refer">refer</span> <span word="to">to</span> 或者 <span word="be">be</span> <span word="replaced">replaced</span> <span word="by">by</span> 等。 一、代词指代关系 题型突破 <span word="it">it</span>/<span word="this">this</span>/<span word="that">that</span>/<span word="they">they</span>/<span word="one">one</span>等代词指代的内容多在该句的前、后句中。找到指代的内容后，把它放到相应位置上验证句子是否通顺并合乎题意，与前后句的内容是否一致，据此判断它是否为正确答案。需要注意的是，有时答案的信息源跨上一段或下一段，难度较大。 二、猜生词词义、熟词新义、句义 题型突破 1．结合画线词语在句子中的成分，由<span word="and">and</span>/<span word="or">or</span>等并列词来确定意义范围，推知其大致意义。对比<span word="and">and</span>/<span word="or">or</span>前后短语或句子的意思，猜测词(句)义。 2．根据该画线词之后的定语、表语、同位语、逗号、括号、破折号等的解释说明来推测其意思。 3．根据<span word="but">but</span>/<span word="however">however</span>/<span word="otherwise">otherwise</span>/<span word="though">though</span>/<span word="on">on</span> <span word="the">the</span> <span word="contrary">contrary</span>等转折关系的词语，或根据<span word="that">that</span>'<span word="s">s</span> <span word="to">to</span> <span word="say">say</span>/<span word="in">in</span> <span word="other">other</span> <span word="words">words</span>/<span word="like">like</span>/<span word="for">for</span> <span word="example">example</span>/<span word="such">such</span> <span word="as">as</span>/<span word="as">as</span> ...<span word="as">as</span>等解释性或举例的词语，或根据 题型突破 <span word="unlike">unlike</span>/<span word="while">while</span>/<span word="on">on</span> <span word="the">the</span> <span word="other">other</span> <span word="hand">hand</span>/<span word="in">in</span> <span word="spite">spite</span> <span word="of">of</span>/<span word="in">in</span> <span word="contrast">contrast</span>等对比关系的词语，推测词(句)义等。 4．根据<span word="because">because</span>/<span word="so">so</span>/<span word="therefore">therefore</span>/<span word="thus">thus</span>/<span word="so">so</span> <span word="that">that</span>/<span word="such">such</span> <span word="that">that</span>/<span word="so">so</span>...<span word="that">that</span>/<span word="such">such</span>...<span word="that">that</span>等表示因果关系的词语来猜测词、句义。 专项训练 题型突破 阅读理解练习 <span word="For">For</span> <span word="five">five</span> <span word="days">days</span>，<span
