length swim是啥意思呀?
长泳麼??
搞不懂...
tatyu and js0421: i don't mean lane swim! and all you guys talked about were the things that i already know! i'm not stupid, i'm in the swim club! humm.. i guess i won't give you guys me five points. but thanks.

(训练或比赛用)长程游泳。
如:
一千米长程游泳 one thousand meter length swim

远程游泳。

Do you mean lane swim? In a public swimming pool, people swim from and to all directions, which is not swimming. In swim training, we separate the pool by floaters into a few lanes, usually 8, which is what you see in a swim competition. When swimmers stay and swim inside his/her lane, we call this lane swimming.

When you swim from one end to the other end of the swimming pool, we call this one lap. After you swim from here to there for 20 times, we say you have done 20 laps.

Please give me your 5 points.

应该是 lane swim = 航线游泳 你听错了 以为是length

一般大的游泳池(通常50米的)回用绳子隔成一道一道的竖线 如果你开车 你会知道道路的跑道叫lane 那么同样的idea````就叫lane swim 比较专业的咯
