假设你是Jessica ，假期中你和父母准备去上海游玩。爸爸妈妈托付你研究一下出行方式。你通过.上网查询，对飞机、火车、自驾这三种出行方式的优缺点做了一番比较。总结信息如下：
   （1）飞机：耗时最短，如果提前（ in advance）订票也会便宜一些，但如果遇到坏天气会在机场等很久；
   （2）火车：比乘飞机花的时间要长，有时费用和机票一样，但最舒适轻松；
   （3）自驾：路程超过10个小时，司机会很辛苦，但沿途可以稍作休息。
   现在请将你的调查结果写一封电子邮件告 诉你的父母。
   要求：
   （1）表达清楚，要点齐全，可适当发挥；
   （2）行文连贯，书写规范；

【答案】Dear Mum and Dad，
   I have compared the three ways of going to Shanghai.Here are the results.Planes take the shortest time.It's also cheaper if you book in advance.But you'll have to wait a long time at the airport if the weather is bad.It takes longer time by train than by plane.Sometimes it costs the same as a plane ticket，but it's the most comfortable and relaxing.The driving distance is more than 10 hours，and the drivers will be very tired.But they can take a break along the way.
   I think  the way to travel that works for you is the best way.
Love，
Jessica
