How can school ban mobile phones completely __________ some of the parents simply don’t follow the rule?
A.unlessB.whenC.untilD.before
B

試題分析:句意:當(dāng)一些家長(zhǎng)不遵守規(guī)則的時(shí)候,學(xué)校怎么能完全禁止手機(jī)呢?when 表示“當(dāng)…時(shí)候”,unless 表示除非,until表示直到…,before表示在…之前,故選B
點(diǎn)評(píng):連詞在高考中涉及到的很多,尤其在賓語(yǔ)從句、狀語(yǔ)從句、定語(yǔ)從句中連詞是必考點(diǎn)。平時(shí)學(xué)習(xí)過(guò)程中,掌握連詞的意思,及所表示的關(guān)系是至關(guān)重要的,這種關(guān)系的判斷可以通過(guò)句子意思的理解來(lái)選擇恰到的連詞。
