应该是排列句子吧

We jump and run( 1 )

Water the flowers( 4 )

We sometimes help( 3 )

We often swim ( 2 )不是排序，是填空happilycarefullyeach otherin the river是真的吗？应该没错。We jump and run happily我们高兴地又跳又跑。Water the flowers carefully细心地浇花。We sometimes help each other我们有时互相帮助。We often swim in the river.我们经常在河里游泳。或We often swim together.我们经常一起游泳。
