1) "was 14 years old then I Frst became interested in archaeology" - There are three mistakes in this sentence. The corrections are as follows:
- "was 14 years old then I" should be "I was 14 years old when I".
- "Frst" should be "First".
- "I am never forget" should be "I will never forget".

Explanation: The sentence should start with "I", followed by the past tense of "to be" (was), the age (14 years old), and then the time marker "when" before the action (I became interested in archaeology). "Frst" should be corrected to "First" to indicate the initial interest in archaeology. Finally, the phrase "I am never forget" needs to be changed to "I will never forget" to express future permanence of the memory.

Corrected sentence: "I was 14 years old when I first became interested in archaeology. I will never forget the feeling of seeing it there in the ground for the first time. It was awesome?"
