Hi does anyone know what is the difference betwwen these two:

1.he is holding the key.

2.he is holding to the key
#2 seems non-native to me.
2. should be 'he is holding on to the key'.
Students: We have free audio pronunciation exercises.
so does it mean both are standard english with the same meaning, am i right?
No. I will be clearer: #2 is wrong; it is not native English. That is my opinion.
Students: Are you brave enough to let our tutors analyse your pronunciation?
