Prepare my Grandparents' Journey to Shanghai
Firstly, we surfed the Internet together to book a hotel and got some information about train tickets. And we were overjoyed to learn that, luckily, the weather in Shanghai will be nice in the following days. The next morning, I went to the train station and waited for a long time before I bought two tickets. After I reached[1] home, I helped my grandparents to prepare their luggages[2],ensuring everything had been packed well. Yesterday afternoon, accompanied by me, my grandparents arrived at the train station safetly[3]. When the train began to move, I waved to them and gave them my best wishes.
Wish them to have a great journey!

修改意见：
[1] reach 表示到达是及物动词，而这里的home前面没有任何限定词，则被视为副词。所以这里改为：arrived home; 或者：got back home.
[2] luggage 是个不可数名词，不要加复数。
[3] safetly拼写错误；改为：safely

点评：22分，是一篇高档次文章，文章整体流畅，用词得体（听了俺的话就是不一样哈）。但稍微偏瘦了一点点，如果能在中间叙述部分稍微增添一丁点笔墨，就能使文章内容更充实，更雄浑有厚度。当然，这就是向满分文章进军了。
比如：when the train began to move 改成：When the train pulled out from the station, roaring away, I waved to them and gave them my best wishes.

最后一段的：Wish them to have a great journey! 改成：They reached out their heads, fixing their eyes on me, their faces beaming with satisfaction. 这仅仅是一种方向，一种熏陶，不要过多可以追求。
