专题二 说明文型语法填空,专题二说明文型语法填空,专题二 专题导读,说明文是对事物的特征、本质、性能、状态，或事物的发生、发展、结果、用途、原理等进行介绍、解释、说明的一种文体。其语言特点有：1多用现在时态。因为说明文通常是对客观事物或事理的一种介绍与解释。2采用客观描述。说明文一般是对客观存在的说明与介绍，因此，语言的表述也应该尽可能地给人以客观可信的感觉。分析句子结构是答题过程中很关键的一步。做题时，首先确定句子的主谓宾成分，看看该句子缺不缺谓语动词，然后再考虑非谓语动词或者其他成分。此时，要借助上下文的暗示或明示，确定需要填入词语的词性、形式和功能等。,专题二

eat因try表示“试图做某事”，后接不定式。6ifif引导虚拟条件句。7a表示泛指的“某一个”小孩，故用不定冠词a。,专题二 新题预测,8better隐性比较级，即“等”比“长”好得多。句中much也提示我们要用比较级，因为much常用来修饰比较级，表示“得多”。9until意为“直到”，引导时间状语从句。10itit指代前文中的the waiting seed。,专题二

lamp，故用现在分词。5Otherwise由本句与前句的逻辑关系可知，要填表示“否则”的otherwise。,专题二 新题预测,6without句意：人生如果没有目标，你将一事无成。7itit指代your objective。8will/can句意：只有这样，你才会知道
