1、Thank you very much for taking me with you on that splendid outing to London. It was the first time that I had seen
the Tower or any of the other famous sights. If I'd gone alone, I couldn't have seen nearly as much, because I wouldn't
have known my way about.The weather was splendid on that day, which I thought was rare. I still remember some people told me that in Britain there was weather and no climate. During the same day, it might snow in the morning, rain at noon, shine in the afternoon and be windy before the night falls. So I think I was lucky。
