Lawrence Craven, a doctor from the USA, is the author of several published reports, one of which introduced the idea in 1953 ________ aspirin could reduce the risk of heart attacks by thinning blood.
A.whenB.whereC.thatD.which
C

試題分析:考查同位語(yǔ)從句:Lawrence Craven,一個(gè)來(lái)自美國(guó)的醫(yī)生也是幾個(gè)發(fā)表的報(bào)道的作家,其中之一介紹了1953年的想法,阿司匹林可以通過(guò)使血液稀薄來(lái)減輕心臟病的危險(xiǎn)。所以這是同位語(yǔ)從句,同位詞是idea,that連接的從句對(duì)idea的內(nèi)容進(jìn)行說(shuō)明。選C。
點(diǎn)評(píng):同位語(yǔ)從句的考查主要看同位詞,一般情況同位詞是一些抽象名詞,如belief,fact,order,news等,這里的that只起到連接作用,不做成分,但that是不能省略的。
