Running a marathon (马拉松)
Have you ever taken part in a marathon? A marathon is 42km long. It is the longest race in the world. To make the runner’s body work, harder training is quite necessary. A runner should start to prepare for a marathon at least three months before. Preparation may have races, many hours of running at different speeds and changes in diet(饮食). During the training time the runner must eat a fit diet.  The diet should have lots of things needed in training the players.
In the early days of training, runners run 80km per week. The running is increased every two or three weeks and at least two long runs per week are needed.
Two weeks before the marathon, the training programme becomes less, from 100km per week down to 60km and then to 30km in the final week. On the last two days they may not run at all.
Breakfast should be eaten at least three hours before the race.  Easily digested(消化) food such as cereal(麦), toast(烤面包) and scrambled(捣碎) egg is best,  with as much fluid(液体) as possible.  Runners should drink water about half an hour before the race to keep up the body fluid. 
【小题1】According to the passage, when should a marathon runner begin his training?

Air is all around us. It is around us as we talk and play. From the moment we were born, We are surrounded(围绕)by air. When we sit down, it is around us. When we go to bed, air is also around us. Wherever we are on the earth, We are surrounded by air. We live in air.
All living things need air, living things can’t live without air. We can go without food or water for a few days, but we can’t live for more than a few minutes without air. We breathe(呼吸)in air. When we are working or running, We need more air. So we breathe faster than usual. When we are asleep, We need less air.
【小题1】From the text, we know that on the earth _____
