1. She was very slow at the beginning, but she didn't give up.
(What is the opposite of 'at the beginning'? Is it 'at the end, in the end or by the end'?)
2. Wilma tried very hard to be able to walk again.

2. It looks like an infinitive phrase acting in the position of a direct object after "tried."
