假设你叫李华。你的英国朋友Andrew下月要来你校学习两个月。他来信请你对他上学期间的交通方式提出建议。现在，请你用英语回一封信，按以下各点答复。
1.建议骑自行车上学；                     2.自行车是学生常用交通工具；
3.骑自行车的一些好处；             4.骑自行车需注意的问题。
注意：1.词数120左右，信的开头和结束语已为你写好（不计入总词数）
2.可根据内容要点适当增加细节，使行文连贯。
Dear Andrew,
       Very happy to hear from you and you're welcome to study in our school for the next two months.
