请问关于现在完成式的两个句子这样表达对吗?例1：i have been China for two years 例 I have been in china for two years.这句子哪儿错了 这句话如何翻译：I have been in China for two years. i have been love you for five years我这样写对吗? I have been (i ) in keeping fish for two years They _____ China for two years.A.have been to B.have been in for these past two years i have been able . The smiths have been in China for two years.改成（ ) ( ) two ye I have been learning English for two years.=It's two years _ I have been in China for 10 years 画 for 10 years 划线部分提问 再帮个忙,哈同义句转换The Smiths have been in China for two years.___ & we've been married for many years 为什么用been married啊?是表达完成式被动
