3.The ongoing global financial crisis will go from bad to worse ______ more attention is paid to the real economy.( 。
A.in case thatB.onceC.provided thatD.unless

分析 如果不多加注意實(shí)體經(jīng)濟(jì),那么持續(xù)的全球經(jīng)濟(jì)危機(jī)將不斷惡化.

解答 答案:D
句意表達(dá)的是轉(zhuǎn)折含義;in case that以防萬一,once一旦,provided that假如,unless除非,如果不;根據(jù)句意,要用unless引導(dǎo)條件狀語從句,表達(dá)"除非多注意實(shí)體經(jīng)濟(jì)",故選D.

點(diǎn)評(píng) 從屬連詞是連詞的一種,用來引導(dǎo)名詞性從句和狀語從句.大致可分為三大類:that(無詞義,不做成分)if,whether (表達(dá)是否的意義,但不做句子成分); 連接代詞:who,whom,whose,what,which,whatever,whoever,whichever(有詞義,在句子中可作主語、表語、賓語);連接副詞:when,where,why,how,how many,how long,how far,however,whenever,wherever (有詞義,作從句的狀語).學(xué)習(xí)時(shí),要注意區(qū)分和掌握.
