XII.重点句型·呈现
语法填空
【解题导语】 文章介绍了跑步带来的多种健康益处。一本医学杂志上的评论及研究表明，跑步不仅能使人长寿，而且可以降低死亡的风险。
1．lnger 解析：考查形容词的比较级。句中有than，应用lng的比较级lnger。
2．t see 解析：考查动词不定式。本句有谓语，因此此处应用非谓语动词；分析句子结构及句意可知，此处应用动词不定式t see作目的状语。
3．dying 解析：考查非谓语动词。“reduce ne's risk f...”意为“降低某人……的风险”，此处介词f后用动词-ing形式作宾语。
4．is 解析：考查动词的时态和主谓一致。本句中宾语从句与主句的时态应保持一致，故用一般现在时；且宾语从句中的主语为it，谓语动词应用单数形式。
5．than 解析：考查介词。根据句中的mre可知，此处应用介词than引出比较对象。
6．that/which 解析：考查定语从句。分析句子结构可知，此处引导定语从句，先行词为a study，且定语从句中缺少主语，应用关系代词that/which。
7．causes 解析：考查名词的数。此处cause是可数名词，意为“原因”，句中的all表示“所有”，后应用可数名词的复数形式。
8．strengthen 解析：考查非谓语动词。分析句子结构可知，此处为动词不定式作目的状语，此处应填动词strengthen，意为“增强、加强”。
9．energetic 解析：考查形容词。and连接两个并列分句，两个分句都表示跑步的特征，and前面的cheap和easy均为形容词，此处应用形容词energetic作表语，意为“需要能量的”。
10．it 解析：考查固定搭配。give it a try为固定搭配，意为“试一
