It was the first week of the summer vacation. Dad said to Mike, “Charlie hurt his foot and can’t      for two weeks. Can you work with      on the boat?” Charlie was Dad’s helper.
Mum said, “We know you had plans with your friends, but Dad really needs your     .”
“Sure, Dad, I would love to,” Mike replied.
Dad and Mike left early the next morning. “Fishing is a(n)     job,” Mike thought. But he kept working. When he found they were      more and more crabs (蟹), Mike was so excited.
It was late afternoon when they returned home. Mum       had dinner ready for them, but Mike was so tired that he went straight to bed.
The next morning Mike’s arms hurt a lot.    , he had such a good time with Dad that he decided to keep helping him. 
The       week(s) passed soon. Charlie came back to work. Mike enjoyed being out on the       , so he asked, “May I come too?”
Dad looked surprised and said, “Sure!”
They all jumped       the boat and set off to the ocean. The rest of the summer would be great for the three of them.
