21、and wait tor her mother.A.where B.what C.how D.who第21页/共24页【答案】1【答案】D2【答案】C 名词性从句的引导词。句意为：她对我们来说是非常宝贵，我们已经准备好做一切来拯救她的生命。3【答案】C 间隔式同位语从句的用法。即先行词是the fact 和that引导的同位语从句中间隔了谓语部分。4【答案】C whoever既作了to的宾语，又作is in charge of International Sales please?的主语。“whoever”作代词，any person whothe person who“任何人”、“无论谁”、

22、“的人”。5【答案】D 此处从做介词to的宾语，是名词性从句，引导词做从句的主语，指人，意思是：无论是谁，选D6【答案】C 句意为：他们必须考虑其中最重要的问题是公共卫生。考查that作代词，that 作代词，往往用于特指，相当于“that名词”，它也只能代替事情不能代替人。7【答案】B8【答案】C 在该题中that引导了一个同位语从句来解释说明news的内容，由于该题把同位语从句后置了，所以很多考生由于不能正确分析句子结构而错误选择了D项。9【答案】D10【答案】B11【答案】A12【答案】D13【答案】A remain是系动词，后加表语从句，由句意可知，从句缺地点状语，所以选A。第22页/共24页Thats all.Thanks for watching！第23页/共24页谢谢您的观看！第24页/共24页
