2--How about the swimming pool at the Central Gymnasium？
 
1--That's boring. I went there last Saturday.
 
2--I think you should go to a swimmer's pool. Oh，we are planning to go to the seaside next weekend. Why not join use？
 
1--Will we be able to swim when we get there？
 
2--Yes，I think so. But you have no diving tower or springboard or any lanes there.
 
1--Now，you!How about the tide there？
 
2--The tide will be out，it'll be safe anywhere. For you won't be able to dive off the rocks. Just when the tide is in，you'll be able to dive.
 
1--That's all right.I like diving but I prefer swimming. When is high tide？
 
2--Low tide was at about nine o'clock in the morning, so high tide will be at about four the next afternoon.

译文：
 
1--我希望我们能去哪儿游个泳。
2--到中心体育馆的游泳池去怎么样?
1--我上个星期六去过那里。那太叫人厌烦了。
2--我想你应该到深水游泳池里去游泳。噢，我们计划个下周末到海边去，为什么不和我们一块儿去呢?
1--去了以后，能在那里游泳吗?
2--我想应该是可以的吧。不过那儿没有跳台，没有跳板，也没有泳道。
1--瞧你说到哪儿去了。那儿的潮汐怎么样?
2--会是落潮。不过那样反倒安全。你不会从岩石上往下跳水吧。只有涨潮的时候，你才可以跳。
1--没关系，我虽喜欢跳水，但我更爱游泳。高潮是什么时候?
2--低潮大概是在上午9点钟左右。那么高潮应该是在第二天的下午4点钟左右。
