()5.Look at this! The dog a ball.
A. play with B. played with C. is playing with

5. C

【分析】首先抓住句中的提示语“Look at this!”，它表示让对方看正在发生的动作，说明句子需使用现在进行时。现在进行时的结构为“am/is/are + 动词现在分词”，需结合主语和动词形式匹配选项。
【解析】“Look at this!”是现在进行时的典型标志，表明动作正在发生。主语the dog是第三人称单数，be动词用is；play的现在分词是playing，因此正确结构为is playing with。选项A为一般现在时，选项B为一般过去时，均不符合语境，故答案选C。
【答案】C
【知识点】现在进行时
【点评】本题考查现在进行时的用法，解题关键是通过提示语判断时态，属于基础时态应用题目。
【难度系数】0.7
