put the words in brackets in Present Perfect. 3. My brother this mountain before. It will be his first time. (NEVER/CLIM)

Solution:

• 3. My brother has never climbed this mountain before. It will be his first time.

Explanation: 'Never' is used to indicate that something has not happened at any time up to the present. The structure is 'has/have' + 'never' + past participle. The past participle of 'climb' is 'climbed'.
