Final answer:
The original sentences have been rewritten with minor changes to the words used.
Step-by-step explanation:
The original sentences are: "Water is pouring into the ship. We sink."
The rewritten sentences are: "Water is flowing into the ship. We go down."
In the first sentence, the word "pouring" is changed to "flowing" to provide an alternative word that still conveys the same meaning. In the second sentence, the word "sink" is changed to "go down" to express the same idea of the ship sinking.
