<p> 动词的时态和语态</p><p> 【专题考点】</p><p> 在具体语境中考查时态和语态，而且题干中有效信息越来越隐藏，加大试题难度是高考时态命题的趋势，考点如下：</p><p> 1 考查一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、现在完成进行时、将来进行时等常见时态</p><p> 2 考查时态和语态相结合</p><p> 3考查主动形式表示被动意义</p><p> 【典例探究】</p><p> 1（2010·山东卷·<span word="T">T</span>30）<span word="Up">Up</span> <span word="to">to</span> <span word="now">now</span>, <span word="the">the</span> <span word="program">program</span> ________ <span word="thousands">thousands</span> <span word="of">of</span> <span word="children">children</span> <span word="who">who</span> <span word="would">would</span> <span word="otherwise">otherwise</span> <span word="have">have</span> <span word="died">died</span>.</p><p> <span word="A">A</span>. <span word="would">would</span> <span word="save">save</span></p><p> <span word="B">B</span>. <span word="saves">saves</span></p><p> <span word="C">C</span>. <span word="had">had</span> <span word="saved">saved</span></p><p> <span word="D">D</span>. <span word="has">has</span> <span word="saved">saved</span>【解析】选<span word="D">D</span>。句意为：截止到现在，这个项目已经挽救了成千上万的本来会死去的孩子的生命。句中的<span word="up">up</span> <span word="to">to</span> <span word="now">now</span>是现在完成时态的一个典型标志，此句要用现在完成时，由此排除其他选择项，正确答案为<span word="D">D</span>项。<span word="would">would</span> <span word="save">save</span>过去将来时；<span word="saves">saves</span> 一般现在时；<span word="had">had</span> <span word="saved">saved</span> 过去完成时，均不符合句意要求。</p><p> 【知识拓展】时态考查题中的标志词或短语在解题中的作用</p><p> 在很多时态类考查题目中，找到解题的题眼就掌握了解题的金钥匙，所谓“题眼”即指一些与特定时态连用的一些表示时间的副词及介词短语。</p>
