It was very nice to get your invitation to spent¡Äweekend with you. Luckily

the

I was completely free then, so I¡¯ll to say ¡°yes¡±. I¡¯ll arrive in Bristol at around 8:00 p.m.

am

in Friday evening.

When I was a very young children, my father created a regular practice I remember well years late. Every time he arrived home at end of the day, we¡¯d greet her at the door. He would ask who we was and pretend not to knowing us, Then he and my mother would have had a drink while she prepared dinner and they would talk about his day and hers. While they chat, my father would lift my sister and me up to sit in the top of the fridge. It was both excited and frightening to be up there!

My sister and I thought he was so cool for putting us there.

Everyone should take the action to reduce haze(Îíö²), which is harmful to our health. First of all, I believe if we plant more trees, there will be less haze in their city. Trees can absorb exhaust fumes(βÆø) from cars, thus reduce pollution. Second, the government should punish the factories where produce too many fumes. Exhaust fumes is the main cause of haze and do greatly harm to people¡¯s health. Maybe we can move factories to areas where few peoples live. Third, I think it was a great idea to encourage people to use public transportation. Last but not least, we can call in citizens to ride bikes if they travel short journeys.
