I know you are busy with your work and study . So I took a taxi to come here from the airport.” I was too ashamed to say a word.My father looked very angry.My grandpa asked me to sit next to him.“Here is a smail gift for you,”he gave his old watch to me and said,“It can tell you what the time is.” People usually say time is money.But this watch tells me more than that.No matter what to do,just do it on time.Yes , I will remember.“Thank you,Grandpa.”,by bus 乘公共汽车,on time 准时，按时,in time 及时,Look forward to … 盼望，期盼,In great joy 兴致勃勃,leave for …动身前往… …,too … to 太… 以至于不能…,hurry to … 急忙前往… …,No matter what … … 无论什么,Here is … …for you . 这是给你的… …,be busy with 忙于… …,get to 到达,by bus 乘公共汽车,get up 起床,in time 及时,after lunch 午饭后,in great joy 兴致勃勃,leave for …动身前往… …,too … to 太… 以至于不能…,hurry to … 急忙前往… …,No matter what … … 无论什么,Here is … …for you . 这是给你的… …,be busy with 忙于… …,English saying, about time,Time is life . 时间就是生命。
