1．(2012·福建高考)China re cently tightened its waters controls near the Huangyan Island to prevent Chinese fishing boats from______in the South China Sea.
A．attacking B．having attacked
C．being attacked D．having been attacked
解析：考查“prevent sb./sth.from doing sth.”结构。根据题意“中国最近加紧了对黄岩岛附近水域的控制，为的是防止中国渔船在中国南海受到攻击”可判断渔船(fishing boats)应该是“被攻击”，故应选择动名词的被动形式，从而排除表示主动形式的A和B两项；D项having been attacked为动名词的完成被动式，表示动作已完成，而题干句意并未表明渔船已经受到了攻击，故排除D项，正确答案为C项。
答案：C
3．(2012·新课标全国高考)This restaurant wasn’t______that other restaurant we went to.
A．half as good as B．as half good as
C．as good as half D．good as half as
解析：句意：这家饭店没有我们去过的另一家饭店的一半好。当形容词与表达倍数关系的词语连用时，其正确表达是：①倍数词＋as＋形容词原级＋as；②倍数词＋形容词比较级＋than。
