翻译（要用定语从句）：

The river whose bank is full of trees is flowing to the sea

the river whose bank covered by a lot of treas runs to the sea

the river which bank is full of trees is going to the sea
绝对对

the river whose bank has a lot of treas runs to the sea

这句话大家翻译的都不对，因为从翻译后的句子来看，这时非限制性定语从句，所以应该翻译成：The river flow into the sea,whose bank is full of trees

the river which bank is full of trees is going to the sea
