The idea of living underwater is often brought up for human beings. It seems to be a great way to keep the land from being too crowded.
In the 1960s，Jacques Cousteau's team built the world's first underwater lab（实验室）. It was called Conshelf I. Two men lived inside of it for a week. Cousteau then improved his lab. In 1963，Conshelf Ⅱwas set up. Since then，there have been many other underwater labs. Aquarius is the only one still running today. It is located 20 meters below sea level in Florida.
The past few years has seen great improvements in technology. The conditions are still terrible. Aquarius only has 37 m2 of space inside of it. Hot water is limited. Showers have to be short. Food is mostly freeze-dried，or jam sandwiches.
Maybe not. Some companies have been working on underwater hotels. These hotels have larger rooms，hot showers and lifts to take guests down. One day，they may actually live up to the romantic dream we have of living underwater.
A. Will life underwater always be like this？ B. This time，the scientists spent 30 days underwater. C. In fact，people have always tried to make it possible. D. It feels even smaller when you are sharing it with other people. E. However，inside underwater labs，things haven't changed much. |
