我站在她10米之外。用英语怎么说？

I am standing ten meters away from her. (现在进行时）。
I stood ten meters away from her. (过去时）。
注意时态。
I stand ten metre away from her (表示一种常态，不可以这样写）

meter 是美国英语拼写
metre 是英国英语拼写

I stand 10 metres to her.

I stand 10 metres away from her好一点

I stand 10 metres away from her.

I stand 10m away from him.
