A：What can I do for you, young man?有什么需要嗎，小伙子?

B：I need to rent three pairs of skates for the morning.我需要租三副今天早上用的滑冰鞋。

A：What sizes do you need?要什么碼的?

B：One pair of 37, and two pairs of 21. One for me, and the other two for two kids.一雙37碼的，兩雙21碼的。一雙給我，另外兩雙是給兩個小孩的。

A：Here you are. And here are three crash helmets.給你。還有這是三個防護帽。

B：Thanks. Well, those two kids are beginners. What should I do about their safety?謝謝。還有，那兩個小孩是初學者，對于他們的安全問題我應該做些什么呢?

A：Well, there are a lot to do, but nothing to worry about. First, make sure they don't go far from the railings.這個，有很多事項需要注意，但也不用太擔心。首先，要保證他們不要離護欄太遠。

B：Oh, yeah, maybe I should ask them just to walk along the railings.哦，是啊，也許我該讓他們只沿著護欄走。

A：That's a good idea. And remind them to be slow at the beginning, not to run into the railings.那是個好主意，另外還要提醒他們在開始的時候慢一點，別撞到護欄上。

B：OK. Anything else?好的。還有別的嗎?

A：Never go to the center of the lake. The ice there is too thin to skate on.絕對不可以走到湖的中央。那里的冰太薄不能滑。

B：Got it. Thanks for reminding me.知道了。謝謝你提醒我.
