I was worried about him sitting there all by himself, 9 I went over and introduced myself. His face lit up when I sat next to him and he told me that he had 10 his big brother, Mike, somewhere in the 11 . I told George that I would help him find Mike and we set off on our adventure (冒险).
We had walked past a couple of enclosures before we finally arrived 12 the monkey enclosure. George was 13 shouting and pointing. He could see Mike! We ran over and Mike was so 14 to see us. He was very sorry for leaving secretly and thanked 15 very much for helping his little brother.
George and I decided we would stay friends from then on. We have kept in touch ever since.
