听力原文： Despite the fact that healthy eating has more publicity than ever before, the sales of chocolate continue to rise.

But why do we like it so much？ It's not enough to answer: "Because it tastes nice." So do other foods. But do you know any other food which some people have to keep closed until their guests arrive？ They know that if they open the chocolate on their own, they'll probably go on eating until they feel slightly ill. And it isn't just the sugar that people like. In the 17th century, when chocolate first arrived here as a drink, people did not put sugar in it because sugar was too expensive.

"Comfort" is a good word to explain why chocolate is more than just another food. It makes people feel safe.

"After a busy day, I like to sit and listen to the radio with a cup of tea and a bar of chocolate."

One answer is that, like coffee, cola and tea, chocolate contains the stimulants. This could explain why it is so difficult to stop eating chocolate once you've started. Some people even fear that they won't be able to atop, and this makes them literally afraid of chocolate.
