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

試題分析:考查動詞辨析和表語從句。Prevent阻止;survive幸存;forbid禁止;leave離開,使…處于…狀態(tài);第二空中的what引導(dǎo)起表語從句,并在句中作為主語。句意:是否能夠找到方法讓中國從經(jīng)濟(jì)危機(jī)中幸存下來正是人們擔(dān)憂的問題。That在引導(dǎo)表語從句的時候,在句中不充當(dāng)任何成分,,只起引導(dǎo)和連接作用。故B正確。
點(diǎn)評:表語從句就是用一個句子作為表語。說明主語是什么或者怎么樣,由名詞、形容詞或相當(dāng)于名詞或形容詞的詞或短語充當(dāng),和連系動詞一起構(gòu)成謂語。解答這類題目,關(guān)鍵在于分析清楚句子結(jié)構(gòu)。通過判斷引導(dǎo)詞在從句中所作的成分及意義,來選擇正確的引導(dǎo)詞。連接表語從句的從屬連詞主要有that, if, whether,和疑問詞(what how where when ...)。that引導(dǎo)表示陳述句的表語從句,if和whether,whether...or not引導(dǎo)表示“是否”,引導(dǎo)一般疑問句。連接代詞主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。連接代詞一般指疑問,但what, whatever除了指疑問外,也可以指陳述。連接副詞主要有when, where, why, how, whenever, wherever, however等.
