　　Many science-fictional ideas from the past have subsequently became scientific realities. Take space exploration, for example. In the 1950s this was just a fantastical idea that few people would have dreamt could actually happen. Now it's such a part of modern life that the latest blastoff of a spacecraft, or the discovery of a new planet often doesn't even make the national news.

　　以前科學小說中提出的很多想法已經變成了科學的現實。拿太空探險來說,50年代,這只不過是一種科學狂想,很少人相信有一天會變成現實。可是現在它已成為現代生活的一個組成部分,以至于一次最新的宇航器發射或者一個新行星的發現已不再列為國內新聞。
