Dear Hung, I received your email last week, but I couldnt answer your question right away. You asked me what Tokyo would look like forty years from now. What a difficult question! To tell you the truth, I have had to think very hard and have finally come up with two predictions. If I take an optimistic viewpoint, I think Tokyo will be a more liveable city. Now it has quite a good public transport system. But people still complain about overcrowded trains during the rush hour. Thats why I believe the government will use advanced technology to build faster trains and make peoples life more comfortable. Whats more, robots will be used to help with the housework. Thus, people will have more time for relaxation. But if I take the pessimistic viewpoint, Tokyo wont be a safe place to live in. Nuclear and radiation accidents have always scared me. Peoples lives will also continue to be threatened because of the continuous risk of earthquakes and tsunamis here. Well, Hung, I hope you are satisfied with my answer. And here is my question: What will Viet Nams capital city look like in the future? Im looking forward to your reply. Giúp mình chuyển bài này về một đoạn văn với ạ
