He swam the river in half an hour. 我在半小时内游过了河。
He accepted his friend’s challenge to swim across the river. 他接受他朋友的挑战,比赛游过河去。
请问老师,这两句一个用的是 swim the river,一句用的是 swim across the river,它们有区别吗?谢谢老师!
曾老师:
没有区别, swim 既可用作及物动词也可用作不及物动词。如:
Her ambition is to swim (across) the English Channel. 她的抱负是游过英吉利海峡。《剑桥高级学习词典》
彭老师:
谢谢老师!
