fingernail

It takes about 150 days to grow out a full length fingernail..大约150天的时间就可以长一个完整的指甲出来。

As I turned on my side I noticed pieces of fingernail, bits of skin and hair on the lift carpet..当我转身侧卧时，注意到电梯的地毯上有零星的指甲、皮肤碎屑和头发。

The top of the box was sealed with wide brown parcel tape, Jacob managed to get his fingernail under the end and peeled off the tape in one go..箱子的顶端是用褐色的包裹胶带封起来的，雅各布用指甲把胶带的一头抠起来，一下子把胶带整个扯开。
