Can you imagine traveling to work in a one-man submarine?

Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea.

  Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen.

   First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems.

    In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology.

   Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers.

   By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of the tides.

    Each new school year brings fresh reminders of what educators call the summer learning gap. Some call it the summer learning setback. Put simply, it means the longer kids are out of school, the more they forget. The only thing they seem to gain is weight.

  Most American schools follow a traditional nine-month calendar with winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than 3,000 such schools at last count.

    They were spread among forty-six of the fifty states. But many experts point out that the number of class days in a year round school is generally the same as in a traditional school. Brenda McLaughlin is a research director at the National Centre for Summer Learning at Johns Hopkins University. She says studies of year-round schooling have not found strong learning gains. Lead researcher Paul von Hippel said, "Year round schools don't really solve the problem of the summer learning setback. They simply spread it out across the year. " Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programmes that can help.

However, calling such programmes "summer school" could be a problem. The director of the summer learning centre at Johns Hopkins, Ikon Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term "summer school". In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents preferred other terms like "summer camp , “extra time”and "hands-on learning

A. helps children to gain weight

53. Why do almost all parents dislike the term "summer school"?

  A. They cherish the children's rights and freedom.

  B. They are worried about the quality of the "summer schools".

  C. They want their children to be forced to make up the gap.
