20、适用于诸如搜索救援和探索等任务,故选B项。 三.答案：-of; spoken; what; which; are introduced; to relax; countries; Traditionally; expression; their解析：考查固定搭配。think of想到,想起。 考查过去分词作定语。spoken 意思为“口头的”,与后面的 written(书面的)一起作定语修饰words。考查宾语从句。从句what we call “body language”作of的宾语,同时what又作宾语从句中call的宾语,表示“的东西”。考查非限制性定语从句。设空处引导非限制性定语从句
21、,先行词为body language,表示物,关系词在从句中作主语,因此用which引导非限制性定语从句。注意:that不能引导非限制性定语从句。考查时态和语态。此处指当我们被介绍给陌生人时,又因为状语从句的时态一般要和主句的时态一致,主句为一般现在时,所以该空应该用一般现在时的被动语态。考查动词不定式。该句中的it为形式主语,因此后面应该用动词不定式作真正的主语。考查名词的复数。此处指亚洲国家中的问候,country为可数名词,由语境可知应用复数名词。考查副词。根据句子结构,此处应该用副词作状语,修饰整个句子。tradition为名词,其副词形式为traditionally。考查名词。定冠词the后面应该用名词形式。express的名词形式为expression。考查代词。由words 可以判断,此空应该填形容词性物主代词their。
