Can you imagine traveling to work in a one – man submarine? Some scientists believe that some day one – man submarines will be as many as automobiles are today．A famous French driver says, “One day soon, men will walk on the ocean floor as they do on the street!” Perhaps during your lifetime people will travel, and live in the sea．

If human beings want to live in the ocean, many human problems will need to be studied first.

Some of these problems, similar to those of living in outer space, are pressure, lack of oxygen and weightlessness. Many questions are still unanswered．For example, can our blood make itself fit for underwater surroundings? What will happen to our muscle if we live in the water very long? Scientists are looking for answers．

Perhaps in the future man will live in the sea, away from the crowded and noisy cities on land．Then sea has plenty of space, not only for floating living buildings and parks, but also for storing supplies and for underwater travel．

Some scientists believe that ocean living will benefit man in more than physical ways. In the freedom and beauty of the deep sea, man may find new sources of joy．

       Teenagers at one German school are learning how to achieve happiness alongside subjects like maths and languages.

       The class sit in a circle with their eyes shut and count from one to ten: one begins, the next voice comes from the far right, a third from the other side. The aim is to listen for an opportunity to shout the number without clashing （冲突）with another voice or leaving a pause. On the first try, most of the young Germans try to be first, while a few are too shy to join in. But by the fifth round, they develop a rhythm.

       The message: giving other people space but also confidently claiming your own space is a requirement for social well-being.

       While the game suggests a soft course for the less bright, the school says it is trying to make it affect even clever pupils. The Willy Hellpach School is the first in the nation to develop a happiness course, intended for 17-19-year-olds preparing for university-entrance exams. "The course isn't there to make you happy," Ernst Fritz-Schubert, the school principal, warned the pupils who were taking the course, "but rather to help you discover the ways to become happy." Cooking a meal together will be one of the class exercises, along with improving body language under the guidance of two professional actresses.

       "In the first period, we had to each say something positive about another member of the class and about ourselves. No laughing at people or teasing," said Fanny, 17.

       The message: self-esteem (自尊) improves happiness too.

       The course is taught for three periods a week and will be graded as a part of overall assessment. Despite the happy subject, the pupils themselves insist it is no laughing matter. Max, 18, says he is happy when he finds people who share his interests. Janina, 18, says she needs to be fit to feel happy.

       "We want to show how proper food or exercise can help in becoming happy," the principal said. He hopes other schools in Germany will copy the idea. The school has attracted national interest since it announced its new course.
