英语博客：A swimming lesson.

 　　Every Tuesday, I volunteer to drive several kids from school to the local swimming pool. They go once a week* for six weeks for a full hour*. It's actually a new experience for my  children to be able to swim during school hours; usually, P.E., or Physical Education, doesn't involve getting wet. So, this is a real treat. The first week, the children were separated into swimmers and non-swimmers. Since then, the swimmers can spend half of their swimming session playing with beach balls on teams. They also are allowed to use various diving boards, while the non-swimmers have an intensive swimming lesson. You could call this their 'immersion 1' session, ha, ha, do you get the pun?* Anyway, for us, it's an unusual and exciting morning. Thankfully, at the swimming pool, there are comfortable seats near the pool, and even internet connection. Infact, I'm writing this as I watch the children swim. The pool is divided into three sections, so three different activities can take place at the same time.* Closest to the edge where I'm sitting is one lane for elderly* people. They usually do gentle exercises, in groups, often with floatation devices. From what I can see, it's more like a social get-together 2. Next to them are two lanes dedicated 3 to adults who just want to swim laps. A lap is a length of the pool. They go back and forth 4 at their own pace, and have about one hour to get their exercise done. They are the most serious swimmers out of everyone here. Perhaps they have a background in* swimming, or simply enjoy the sport, and wish to include it as part of their healthy routine. So, as you can imagine, I sit here on Tuesday mornings, looking out over the pool, and observe all sorts of interesting activity. This pool is well equipped as far as safety is concerned*. There are two lifeguards on duty at all times, who constantly scan* the pool. They wear red t-shirts and carry red floatation devices, and are ready at any second to either blow a whistle, or to jump in and rescue someone. As I look around the room, I see more safety devices: rubber rings, stretchers for enabling disabled people to float on and enjoy the water, and even a fire extinguisher! You would have thought that that wouldn't be necessary. The swimming teacher is explaining to the kids at the moment the importance of timing 5 in swimming, how you have to use your arms and legs at different times in order to get fast movement through the water. She explains this with the help of a swimmer volunteer, and now the children are taking turns swimming a lap using her advice. And guess what? I see improvement already! She is a devoted 6 swimming teacher. I've never seen her out of the water; it's as if she's a part of the pool. They've got ten minutes left to swim; the kids never want to get out of the pool. They would rather stay here than go back to school.
