帮助翻译几个简单句子

1.你以前来过中国吗?
2.你要在这里呆多长时间
3.有去过中国的其他地方吗
4.你们公司与这家公司合作多少年了?
have you ever been to china before有点不对吧~~~因为说话的对象本来就在中国,不能用TO 应该用 in比较正确吧???

Have you ever been to China before?

How long are you going to stay here?

Have you ever been to other places of China?

How long have you cooperated with this company?

也没错的!!嘿
用现在分词表示影响比较好哦~~~!

1. Have you been in China before?
2. How long are you going to stay here?
3. Did you go to other places in China before?
4. How long did you work together with this company?

没错的。

对补充：楼主说得没错，用in的确比较合适，但是也可以说to，在中国内不一定要用in。说的时候可能也是指以前，以前不再中国就用to。

1.Have you (ever) been to China before?
2.How long are you going to stay here?
3.Have you been to other places in China before?
4.How long have your company cooperated with this company?
这些句子中很大一部分都应该用完成时。

1、Have you been to China before?
2、How long will you stay here?
3、Have you been to any other place in china?
4、How many years have you worked with this company?

Have you been China before? 你以前来过中国吗?
