Do you go to the movies during the holidays? What do you eat there? Popcorn (爆米花)? Yes, of course! More and more Chinese youth now like to eat popcorn when they watch movies at the theater.

However, it may be the Americans who love popcorn the most. Americans do fun things with their popcorn. They like to put butter on their popcorn. But that's not all; they also like other kinds of things like chocolate, and even cheese! Americans like to eat popcorn as a snack (小吃). These days, there are a lot of "low -fat" kinds of popcorn in US shops to keep people healthy.

Americans started eating popcorn in movie theaters in the 1930s. Before this, they couldn't because movies were silent (无声的) and popcorn made too much noise. When movies got noisier, people could eat noisier food.

Next time you eat popcorn, why not try to eat it American style.
