阅读短文，选择正确答案。 Popular breakfast foods in the United States, as in many other countries around the world, include coffee, milk, juice, eggs and bread. Some other breakfast items served in the United States are thought by many to be traditionally American. However, they actually come from other countries. A very popular breakfast food in America is the pancake---a thin, flat cake made out of flour and often served with maple syrup. The idea of the pancake is very old. In fact, pancakes were made long ago in ancient China. Bagels, a round thick bread with a hole in the middle, are also popular for breakfast in America. Polish people in the late 1600s came up with the idea for the first bagels and this new kind of bread soon took off across Eastern Europe. In the late 1800s, thousands of Jews from Eastern Europe traveled to the United States and brought the recipe for bagels with them. Today, New York bagels are said to be the best in the world. Many people have them with cream cheese for breakfast on the go. Doughnuts (usually spelled 'donut' in the United States) came from France. They were served to American soldiers in France during World WarⅠ(第一次世界大战). After the war, American soldiers asked cooks in the United States to make doughnuts for them. Now, served with coffee, they are a very popular breakfast food across the United States. 1. This reading is mainly about _______.
