看了刘谦的表演,许多孩子都对魔术着了迷.
Many children have become interested in magic since they watched Liu Qian 's show.
答案上是这么写的.为什么是have become 这是什么时态 ..
现在完成时不应该是have became
这里是have become
答
对你无语，好好看现在完成时的结构
答
have became 是过去式。。。become是现在完成
答
这是现在完成时.孩子对魔术感兴趣是在看了表演之后,是看表演之后的一个状态,所以用现在完成时.也就是说看表演已经完成了,孩子们才感兴趣.现在时：become 过去时：became 现在完成时：become
答
现在完成时 have+动词的过去分词
