问题描述：
关于现在完成时的一些问题.现在完成时变一般疑问句和否定句的结构.
现在完成时变一般疑问句,句中的already照抄吗?
像这样：I have already seen that film.是不是变成Have you already seen that film?
变疑问句的时候seen要不要变成原形?
还有就是变否定句,He has already painted the bookcase怎么变?
这还有一道题：Have you been to Beijing____?是填already还是yet?
答
1) Have you already seen that film?
2) He has not painted the bookcase yet.
3) Have you been to Beijing already?
答
already 和yet是现在完成时的标志.
already用于肯定句,可以放句子中间或末尾；
yet用于否定句和疑问句,放句末,当肯定句中有already变否定、疑问句要变成yet.
所以我想聪明的你应该知道答案了!
