Oh, Mary, why are you killing your time this way ?Can’t you find something____ doing at all?
A.usefulB.valuableC.worthD.good
C

試題分析:考查固定搭配。固定搭配sth be worth doing某事值得被做;本句中worth doing修飾名詞something。句意:Mary,為什么你用這種方法來消磨時(shí)間呢?你難道就不能找到值得做的事情嗎?故C正確。
點(diǎn)評:固定搭配是學(xué)習(xí)語言的重要環(huán)節(jié)。要掌握好英語,記憶相當(dāng)數(shù)量的詞組是必不可少的。英語中的每一個(gè)詞組,不僅表達(dá)一定的概念,具有一定的詞匯意義,而且在語音、拼法、語法等方面都有自己的特點(diǎn)。在學(xué)生學(xué)習(xí)英語的過程中,單詞、詞組記憶是基礎(chǔ)。解答這類題目,關(guān)鍵是理解題干意思以及各選項(xiàng)詞組的意思,可以像數(shù)學(xué)中的代入法一樣,依次把各個(gè)選項(xiàng)意思放入句子中進(jìn)行比較,不難選出正確答案。
