"My sister runs every night."

Translation: 我的妹妹每天晚上跑步。

[RossGarton]

妹妹 = "sister" now? I'm seeing lots of inconsistency here. When I translate it as "sister" it's marked wrong for not being specific enough

[daltonstout59]

time can go either before or after subject - very incosistent throughout the tree

我姐姐每晚跑步 is also fine...
