A.is leading toB.is resulting in C.are contributing toD.are owing to

答案
C

试题分析:考察主谓一致和词义辨析。Activities 是从句的主语,所以选C和D; 按句子意思应选词义为“导致”的选项contribute to.故C正确。
点评:在英语中,句子的主语和谓语动词要保持数上的一致关系,叫主谓一致。这种关系通常要遵循下面三条原则:1.语法一致原则。句子的主语是单数形式,谓语动词要用单数形式;主语是复数形式,谓语动词用复数形式2.意义一致原则即谓语动词该用单数还是复数取决于主语所表达的内容在含义是单数意义还是复数意义。3.邻近原则谓语动词该用单数还是复数形式,取决于最邻近它的名词、代词或其它词的数。
