あと 次は,中学生のタケシ ( Takeshi) が書いたスピーチの原稿 の1~6の問いに答えなさい。 I am going to talk about my interesting experience. I went to London during this summer vacation with my family. This was my first trip to a foreign country. I wanted to know about London, so I looked for information about it on the Internet. I was able to see many famous things on the Internet before the trip.
