5．-When is he willing to lend his friends some money？
-Only when ______ hard enough．（　�。�
A．to pressB．pressedC．pressingD．is pressed

分析 --他什么時候愿意借給朋友一些錢呢？
--只有在他受的壓力足夠大的時候．

解答 答案：B．
本題的回答為省略句，其完整的句子應(yīng)為"He is willing to lend his friends some money when he is pressed hard enough．"因主句和從句主語一致，且從句謂語動詞是be動詞，所以從句中的主語和be動詞可同時省略，動詞press與它的邏輯主語he之間又是被動關(guān)系，所以用過去分詞pressed，故選B．

點(diǎn)評 本題考察的是狀語從句的省略，當(dāng)狀語從句的主語和主句主語一致，且含有be動詞的時候，可以把狀語從句的主語和be動詞一起省略．到底用現(xiàn)在分詞還是過去分詞，看動詞與它的邏輯主語之間的關(guān)系（主句的主語就是非謂語動詞的邏輯主語），即主被動關(guān)系（主動關(guān)系就用現(xiàn)在分詞形式；被動關(guān)系就用過去分詞）．
