Whether ways will be found to help China _______ the current world financial crisis is just _______ worries the public.
A.prevent ;thatB.survive ;whatC.forbid; thatD.leave ;what
B

试题分析:考查动词辨析和表语从句。Prevent阻止;survive幸存;forbid禁止;leave离开,使…处于…状态;第二空中的what引导起表语从句,并在句中作为主语。句意:是否能够找到方法让中国从经济危机中幸存下来正是人们担忧的问题。That在引导表语从句的时候,在句中不充当任何成分,,只起引导和连接作用。故B正确。
点评:表语从句就是用一个句子作为表语。说明主语是什么或者怎么样,由名词、形容词或相当于名词或形容词的词或短语充当,和连系动词一起构成谓语。解答这类题目,关键在于分析清楚句子结构。通过判断引导词在从句中所作的成分及意义,来选择正确的引导词。连接表语从句的从属连词主要有that, if, whether,和疑问词(what how where when ...)。that引导表示陈述句的表语从句,if和whether,whether...or not引导表示“是否”,引导一般疑问句。连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述。连接副词主要有when, where, why, how, whenever, wherever, however等.
