I should listen to her words.
希望能帮到你,祝更上一层楼O(∩_∩)O
有不会的欢迎再继续问我(*^__^*)Where have you --------?Tom has _______to the library. And I went there to ask him some question.用been 和gone填Where have you been?Tom has gone to the library. And I went there to ask him some questions.能解释一下吗？have been是指去了某地又回来了，即现在在说话的地方。而have gone是指去了某地，还没回来，即不在说话的地方。你刚才去哪了？（因为是在对话，显然是回来了）汤姆去图书馆了，我去那问他几道题。（汤姆去图书馆，现在还没回来，不在说话的地方。）
