have ever 为什么后面加been

have ever 为什么后面加been have been keeping doing 为什么错了是因为have been后面不能加状态么 have you ever been traveled to another province为什么province不加s? have you ever been to an aquarium? have you ever traveled to an other province 为什么一个加been一个不加啊 have beenhave ever been后面分别跟什么? I have ever been 英语语法 ...would have been 后面加什么? 现在完成时have后什么时候后面加been? 完成时HAVE后面什么时候加BEEN 现在完成时have/has为什么后面有时加动词的过去分词,有时加been I have ever been there.I have ever been to BeiJing.第一句加to第二句去掉to为什么不行,ever用法对吗there其实也指具体的一个地方了 为什么Have you ever been to HK要用Have been不用have gone? have been 和have ever been区别! 英语 画线句子的could后面为什么要加have been 反义疑问句区分We have ever been to Shanghai,haven”t we?You have a headache,don’t you?为什么第二句后面不是haven't you? Have you ever eaten in McDonalds,or at KFC为什么一样是加地点,前面用 in 后面用at? How long have you ever been on our school team?为什么不用 have been in Have you ever been employed?
