     Last weekend, I help my grandparents prepare their trip   
to Beidaihe. In Saturday morning, together with my grandparents,
I searched Internet for the train schedule, the weather in Beidaihe,  
and some hotel information. In the afternoon, I went back to the train 
station and managed to buy two ticket for my grandparents 
because there was a long queue. After dinner, I packed
the suitcase with the things their grandparents needed, such as clothes,

the station to see them off. Waved goodbye to them on the 
platform, I felt happily for them and wished them a safe journey.   		1.________
