今年は、映画「Back to the Future」 (http://en.wikipedia.org/wiki/Back_to_the_Future) の３０周年記念です。もし、あなたがタイムマシンを１回使えるとしたら、いつ（どの時代）に行ってみたいですか？ もちろん、過去でも未来でもかまいません。なぜそこに行ってみたいのか、また何をやってみたいのかを具体的に記述してください。
I had a chance to time travel, I think I would go to the future. Basically, I am wondering if humanity is going to make it into the future. There are so many serious problems today including global warming, food shortages, and pollution. I would like to go about 50 years into the future to make sure we make it through. I would also very much like to know how my kids do. It would be nice to know that they do well and I have a comfortable life.
