An English composition about a six-day trip to London

My trip to London Last summer vacation, I went to London with my parents. At first, I went to Buckingham Palace (I know you don’t know it, please note: Buckingham Palace), it was very great! It's so beautiful! Second, I went to the British Museum, it was a little boring. I was unhappy. And then, I went to Thames River, it was so clear. At last, I went to Big Ben, it was really big. I love London very much, what about you?
