After decades of effort, the city is still trying to _____ how to stop smoking in public places.
A.try outB.let outC.figure outD.run out
C

試題分析:考查動詞短語辨析。A嘗試;B泄漏;C查明,發(fā)現(xiàn);D用完,耗盡;句意:經(jīng)過幾十年的努力以后,這座城市仍然還在如何在公共場所禁止抽煙。故C正確。
點評:動詞的短語辨析要根據(jù)上下文的語境進行,要把短語的意思和句意相結(jié)合。同時也要注意一個短語多種意義的現(xiàn)象,如pick up 撿起;用車接;無意中學會;接受信號;康復;謴停蝗旧稀;在平時的學習中要把同種類型的短語放在一起比較,如同一個動詞+不同的介詞/副詞;同一個介詞/副詞+不同的動詞。諸如此類的固定短語,屬于最基本的知識,如果學生有錯誤,則應該加強背誦并平時多解題,進而加以鞏固.
