十岁大的儿子小宝突然对我说,他想学会骑单车。我想想,好像也没有什么理由可以反对的,就答应了他。以后几天,我都在送完牛奶后,把车座后的送奶箱卸下来,然后等我下了班,儿子放了学以后,我再带着他在我们租房前的一片空地上练习骑单车。 Ten-year-old son Andy suddenly told me that he wanted to learn to ride a bicycle. I think, as if there is no reason to object, he agreed. After a few days, after I had delivered the milk, I took off the milk tank behind the car and waited for me to go to work. After my son left for school, I practiced with him on an open field in front of us Cyclist.
