Some families live quite far in the UK.Visiting them can either be an adventure or a chore(麻烦事).It depends on how much family members like each other.

If all goes well,kids have an exciting time.Your relatives will plan different fun activities and make you happy.Taking you to visit relatives gives your parents a chance to rest.It gives older relatives a good chance to relive the time when they had young kids.If they do not have children of their own,they get to play parent for a while.

I remember that Blackpool Pleasure Beach was the place I liked to go with my grandparents

It is an amusement park on the northwest coast.It is packed with roller coasters(过山车)and candy stalls(糖果摊).You could race small boats on a lake or scare yourself into death riding the ghost train.I had good memories of my time there.

As you get older,you suddenly become the one who must help your relatives with their kids.I have four COUSINS aged between one and eleven.They are fantastic and I really enjoy seeing them.However,it is very tiring,as they get so excited and energetic(充满活力).I fall asleep hoping they will remember our good times when they get older.
