     Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer
model to predict how just three grams less a day would affect heart disease in the United States.
     The result:10％ fewer heart attacks.8％ fewer storkes.4％ fewer deaths.11％ fewer new cases of
heart disease. And 240 billion dollars in health care savings.
     Researchers found it could prevent 100,000 heart attacks and 92,000 deaths every year.
     The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of
California San Francisco was the lead author. She says people would not even notice a difference in
taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at
Stanford and Columbia University.
     Each gram of salt contains four hundred milligrams of sodium(钠),which is how foods may list their
salt content.
     The government says the average American man eats ten grams of salt a day. The American Heart
Association advises no more than three grams for healthy people. It says salt in the American diet has
increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can
mean a lower blood pressure.
     New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction
Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government
interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list
calorie information. Now a study by the Seattle Children's Research Institute shows that the calorie
information on the menu can influence what parents order for their children.

     Even people who don't understand English can enjoy Chaplin's films because they are mostly silent. It
isn't what he says that makes us laugh. It depends upon actions which mean the same thing to people all
over the world. He is master of the art - a kind of world language.
     As a young man, he and his brother traveled to America in a small company of actors. Chaplin was
then invited to join a new company that was making film comedies. Very soon he had made dozens of
short films for this company. And it was in his second film that he wore the clothes which made his
reputation - black hat, tight coat, baggy trousers, huge shoes, moustache and walking stick. He intended
simply to make people laugh. But the odd make-up made him look both comic and sad.
     By the time he was thirty, Chaplin was the greatest, best known and best loved comedian in the world. He received thousands of dollars for each film he made. He had formed his own manner of acting. He was welcomed by excited crowds wherever he went. But he worked very hard and had few close friends.
Perhaps that is why the sad side of the little tramp began to show more clearly in the films he made. The
little man began to want more than food and a roof over his head. He began to want love.
     In one of his most famous films "The Gold Rush" a girl plays tricks on the little man. Then she begins
to feel sorry for him and treats him kindly. He mistakes her pity for love. The girl in "City Lights" is blind. She thinks he is the most wonderful man she has ever met. But then she recovers her sight and sees what
a foolish figure he is. This sadness gives Chaplin's films a depth of human experience which few comedians can equal.
     After living in America for forty years he moved to Switzerland. There he died on Christmas Day
1977. He once described himself as a citizen of famous pictures that were made during the 1920s and
1930s, the time of the silent films. But, to many people all over the world Chaplin will always be the king
of comedy.
