问题描述：
she must have gone to sleep ane ___about me and the dog.为什么填forgotten
答
she must have gone to sleep and have forgotten about me and the dog. 与gone并列
答
简单地说，and前后是并列的，gone是过去分词，forget同样也用过去分词形式
答
整句是She must have gone to sleep and （must have forgotten）about me and the dog.
have+过去分词,就用forgotten
