These boxes ______ for keeping the food clean and cool.

A.useB.a(chǎn)re usedC.have usedD.were using

B

解析試題分析:句意:這些箱子是用來保持食物清潔和保鮮的。結(jié)合語境可知本句描述的是客觀性動作,故用一般現(xiàn)在時態(tài)。主語是動作對象,故用被動語態(tài),選B。
考點:時態(tài)及語態(tài)
點評:英語中的時態(tài)主要是借助于時間狀語與上下文語境來進行判斷。解答此類題型,首先要注意句子中的時間狀語,如果沒有則要通過分析上下文,結(jié)合語境來判斷句子的時態(tài)。語態(tài)的判斷主要是確定句子主語與謂語動詞的關(guān)系。如果是主動關(guān)系則用主動語態(tài),反之如果是動賓關(guān)系,則用被動語態(tài),尤其要注意一些特殊動詞的用法。
