完型填空的训练及解题技巧（含答案）
完型填空
一、文章特点
科技信息类文章是指介绍当前科学领域的最新科技成果或者正在研发的科技项目的文章。2007年广东高考完形
填空题的短文就属这类文章。这类文章有清晰、客观、准确、精练和严密等特点。如果考生对该技术有所了解，对解题是有一定帮助的，但是归根结底还是取决于对文意的透彻理解、对词语的意义和用法的掌握，也离不开解答完形填空的一些技巧。
二、解题技巧
1. 把握语境，一气呵成。
完形填空是要求考生根据上下文语境来进行确定最佳选项的。做题前，必须要结合上下文所给的提示（明示或暗示），对文章整体进行理解和把握。因此，快速浏览全文，掌握短文大意和文中用词习惯，才能在解题时做到一气呵成。
2. 先易后难，各个击破。
做题时碰到有充分把握的先做，不确定的姑且先放一放，待处理完其它的答案时，再回头处理，这时由于对文章有了进一步的理解，往往可能会眼前一亮，有“山重水复疑无路，柳暗花明又一村”之效。
3. 善用文中信息，进行逻辑推断。
做几何证明题时，需要有足够的条件，才能推导出结果。做完形填空时也是如此，需要搜罗证据，再进行逻辑推断，才能得出正确的答案。如2007年广东省高考完形填空的第21空就是应用该能力推敲出来的。
证据一：...we didn’t have to remember passwords.
证据二：...uses face recognition technology to log you on to windows. 证据三：...all you need is a webcam and your pretty face. 收集了这三个证据后，推断出automatically就顺理成章了。 4. 善用关联词语，把握逻辑关系。
文章的逻辑关系大多通过一些过渡性的关联词来实现，这些关联词能给考生指明答题方向。常见的表示逻辑关系的关系词有：表并列关系的and, also, as well as等；表转折关系的but, however, yet等；表因果关系的because, because of, as, since, for that reason, so, therefore, thus, as a result等；表递进关系的besides, in addition, additionally, moreover, furthermore, what’s more等；表选择关系的or, either…or等。
5. 养成阅读习惯，丰富背景常识。
丰富的常识及文化背景知识有利于解题，考生平时要养成课外阅读习惯以扩大自己的知识面。如考生是电脑软件的发烧友，解答2007年广东省高考完形填空题就顺利得多。
