14.Look!The children ______ in the river.( )| A. | swim | B. | are swimming | C. | is swimming | D. | swims |
分析 看!孩子们正在河里游泳.
解答 答案:B.考查现在进行时态.句意"看!孩子们正在河里游泳.".A动词原形.B现在进行时态.C现在进行时态.D第三人称单数.根据look看,正在进行的动作,可知应该用现在进行时态,结构是am/is/are+动词的现在分词.主语children孩子们,复数形式,因此用be动词复数are,swim的现在分词是swimming.答案是B.
点评 现在进行时态表示正在进行的动作,结构是is/am/are+动词的现在分词.be动词的单复数要与主语的单复数保持一致,结合语境完成试题.
