The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.
Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a hose(软管) and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜函病). The bends can cause a diver to double up in pain. They can even kill him.

Should Good Sportsmanship Be Taught in School?
Almost everyone feels that it is important for young people to win fairly and show respect toward others.Should good sportsmanship, then, be taught in school? Critics do not think so. 71 Presented here are the most important benefits of teaching sportsmanship.
Teaching good sportsmanship and having a positive attitude in activities like sports, class elections, and science fair competitions are critical to success in school. 72 Acting calmly under pressure helps young adults succeed not only in sports but also in life.
73 A person cannot play by the rules if he or she does not understand what the rules are.Knowing the rules also applies to other activities.If students enter a science fair competition, for example, they must follow the guidelines. Those who know the rules are much more likely to succeed.When students learn sportsmanship, they discover, how knowing the rules relates to achievement.
Good players become skilled at handling responsibility.When people accept responsibility, they achieve their best.Positive thinkers, moreover, influence others, especially those who are struggling with a problem.A gifted basketball player, for example, might teach skills to a less-talented player.Helping others raises the performance of the entire team.The team, consequently, could reach new heights and set new records. 74 Those who do not practice sportsmanship pass off responsibility.For them, if an opportunity is lost, it is someone else' s fault.When students participate on a team, they benefit by learning to accept responsibility, encourage others and own up to mistakes.
Sportsmanship is a winning idea.It must be taught in school.Students need direction to become good sports".Students will be responsible for their own actions and will have a positive influence on others.As students enter the workforce, businesses benefit.The community also benefits because these students will someday become leaders. 75

When you see homework covering the kitchen table and toys are piling up around the sofa,you probably wish there was a bit more space.You are not alone.Nearly a third of parents say they feel squeezed into their homes but cannot afford to move to a bigger property,a report reveals today.
Twenty—nine percent say ‘their property is too small to fit the size of their family’—rising to 40 percent for those 34 and under.One in four children is ‘forced to share’ a bedroom,according to the Finda Property,com website.Property analyst Samantha Baden said:“Afford ability remains a key issue for families,with the average cost of a three-bedroom home around £193,000.”Very few can afford to buy—or to rent—a property of the size they want and in the area they desire to live in,according to Miss Baden.
A recent report,from investment firm LV,also found that many‘ space—starved parents’ are pushed into a two—bedroom home which was perfect when they were a young couple,but has no space for three or so children.Grown—up children who cannot afford to leave home are also adding to the problem facing families in Britain's ‘big squeeze’.
For a home to be the correct size, which means it is not overcrowded,parents must have their own bedroom.Children under ten can share, as well as same—sex children between ten and 20.Anyone over 21 also needs their own room.
