1)黑猩猩一边思索一边抓头,弄不清如何打开上锁的盒子(scratch)

The chimpanzee was thinking while scratching its head. It didn't know how to unlock the box.

The chimpanzee is deliberating and grasping , it can not distinguish to how to open lock of the box
是解释这段话还是怎么的啊？

来个垃圾点的~
The chimpanzee catches the head while considering, does not understand how to open the box locked
