Dear ..(tên bn kia).last email asked me about my city Ha Noi in 2050.Well , but I'm busy and have no time to reply you soon . Today i m writing to you about that question. There are diffirent ideas about this question . I thought about it in a few days , and now I can give you some predictions.Let's take a look at optimistic aspects .In2050 Ha Noi will become a more modern city for lots of reasons.High technology has been applied in our lives .The robots will be commonly used in the road. They will help human beings to decrease the accidents as traffic jams. On the contrary ,pessimistic people think that the city life will be a dangerous place to live in because the environment is completely polluted. The effects of global warming have great impacts on the city dwelles,highter temperature in the summer and colder climate .there a lot of mean stransport so that emission from them cause air pollustion. That all about my thought about your question .I hope you will be satisfied with it, ...(tên bạn kia) Best wishes (Tên của bạn)
