    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.

阅读下文，完成文后各题。

孝文皇帝，高祖中子也。高祖十一年春，已破陈豨军，定代地，立为代王，都中郡。太后薄氏子，即位十七年，高后八年七月，高后崩。九月，诸吕吕产等欲为乱，以危刘氏，大臣共诛之，谋召立代王，事在吕后语中。

孝文帝从代来，即位二十三年，宫室苑囿狗马服御无所增益，有不便，辄弛以利民。尝欲作露台，召匠计之，直百金。上曰：“百金，中民十家之产，吾奉先帝宫室，常恐羞之，何以台为！”上常衣绨衣①，所幸慎夫人，令衣不得曳地，帏账不得文绣，以示敦朴，为天下先。治霸陵皆以瓦器，不得以金银铜锡为饰，不治坟，欲为省，毋烦民。南越王尉佗自立为武帝，然上召贵尉佗兄弟，以德报之，佗遂去帝称臣。与匈奴和亲，匈奴背约入盗，然令边备守，不发兵深入，恶烦苦百姓。吴王诈病不朝，就赐几杖。群臣如袁盎等称说虽切，常假借用之。群臣如张武等受赂遗金钱，觉，上乃发御府金钱赐之，以愧其心，弗下吏。专务以德化民，是以海内殷富，兴于礼义。

后七年六月已亥，帝崩于未央宫。遗诏曰：……令中尉亚夫为车骑 * * ，属国悍为将屯 * * ，郎中令武为复上 * * ，发近县见卒万六千人，发内史卒万五千人，藏郭穿复土属 * * 武。乙巳，群臣皆顿首上尊号曰：“孝文皇帝”。太子即位于高庙。丁未，袭号曰“皇帝”。

太史公曰：孔子言“必世②然后仁。善人之治国百年，亦可胜残去杀”。诚哉是言！汉兴，至孝文四十有余哉，德至盛也。廪廪乡改正服封禅矣，谦让未成于今。呜呼，岂不仁哉！
