1. The ability ______ an idea is as important as the idea itself. (2011·湖南卷21)
A. expressing B. expressed
C. to express D. to be expressed
【解析】选C。主语the ability 为“能力”，抽象名词。通常使用动词不定式作定语。句意：表达思想的能力与思想本身同等重要。我们也可以联想到be able to do “能够干”而得出答案。
2. The players ______ from the whole country are expected to bring us honor in this summer game. (2011·湖南卷23)
A. selecting B. to select
C. selected D. having selected
【解析】选C。select 与the players 间有动宾关系。因此select用过去分词形式表被动完成。句意：从整个国家挑选出来的运动员有望在今年的夏季运动会给我们带来荣誉。
