他曾经来过中国么? 英语怎么说

各位说的都不对，我来美国十年了，是美国永久居民，所以英文还是可以的。这句话：“他曾经来过中国么？”在美国英语中的说法是：
Has he been to China? 如果加强语气，可以加一个ever：Has he ever been to China?

1. He went to China before.
意思: 他以前有去过中国.

2. He have been to Chine.
意思: 他以前有在中国呆过．

He had been to China

Has he ever been to China?

HAS HE BEEN to China before?

has he ever been to China?
