Question

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？
求解！要快点！急！！！！！！！！！！！！！求各位人士帮忙啊！

Answer 1

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！

Answer 2

1) Have you already seen that film?
2) He has not painted the bookcase yet.
3) Have you been to Beijing already?
