2．(2011山东高考)Look over there—there’s a very long，winding path ______ up to the house.
A．leading B．leads
C．led D ．to lead
解析：句意：看那儿——有一条很长的，蜿蜒曲折的小路通向那座房子。leads用作谓语动词，本题的there be句型中已有is，故排除B项；path与lead之间是逻辑上的主谓关系，又由题中的动词look可以判断lead这一动作不是表示将来的动作，故可以排除过去分词短语和不定式短语充当的后置定语，即排除C、D两项。在本句中leading up to the house作后置定语，修饰path，相当于定语从句which leads up to the house。
答案：A
3．(2011江苏高考)Recently a survey ______ prices of the same goods in two different supermarkets has caused heated debate among citizens.
A．compared B．comparing
C．compares D．being compared
解析：句意：最近，在两家不同超市对相同商品进行的一次价格比较调查引起了市民热烈的讨论。分析句子结构可知，句子谓语动词为has caused，故空格处应为非谓语动词形式，来充当a survey的后置定语。a survey与compare之间存在主动关系，故用现在分词。实际上现在分词短语comparing prices of the same goods in two different supermarkets相当于定语从句which/that compares...。
答案：B
