How could I make it easily and fastly for improving my spoken english? I have a planning to go to american and canada in this summer ,which lnclud visiting my old friend , Driving to California and Silicon Vally , Walking in New york and Wall Street and so on. American is a dram when I was a child ,and it may come true for the coming months. I am looking forward to have a perfect trip ,howerver ,my spoken english is so awful that I couldn't do simple talk with others. God , I need someone's help!!!!
