Congress makes the laws in the United States. It has two pans, which are more or less equal in power. They are known as the House of Representatives and the Senate. The House of Representatives is larger than the Senate whose 100 members (two from each state) serve for six years. The 435 members of the House are elected every two years, and the number from each state is determined by the population of the state. For example, California, which has a large population, has 43 representatives, while the State of Nevada has only one.

The House and Senate are divided into small groups which take care of special matters such as education or foreign affairs. The most important work of Congress is often done in these groups, which are called subcommittees.

According to the Constitution of the United States, a senator must be at least 30 years old and he must have been a citizen of the United States for nine years at the time of his election. To be elected to the House a person must be 25 years old and must have been a United States citizen for seven years. At the present time, members of Congress include businessmen, farmers, teachers, and especially lawyers. In general, senators are better known than representatives because they are fewer in number and serve for a longer time. Many American presidents served in Congress before they became president.

蜩与学鸠笑之曰：“我决起而飞，抢榆枋，时则不至，而控于地而已矣，奚以之九万里而南为？”适莽苍者，三餐而反，腹犹果然；适百里者，宿舂粮；适千里者，三月聚粮。之二虫又何知？

小知不及大知，小年不及大年。奚以知其然也？朝菌不知晦朔，蟪蛄不知春秋，此小年也。楚之南有冥灵者，以五百岁为春，五百岁为秋；上古有大椿者，以八千岁为春，八千岁为秋。而彭祖乃今以久特闻，众人匹之，不亦悲乎！

汤之问棘也是已。穷发之北有冥海者，天池也。有鱼焉，其广数千里，未有知其修者，其名为鲲。有鸟焉，其名为鹏，背若太山，翼若垂天之云，抟扶摇羊角而上者九万里，绝云气，负青天，然后图南，且适南冥也。斥鷃笑之曰：“彼且奚适也？我腾跃而上，不过数仞而下，翱翔蓬蒿之间，此亦飞之至也。而彼且奚适也？”此小大之辩也。

　　故夫知效一官，行比一乡，德合一君，而征一国者，其自视也亦若此矣。而宋荣子犹然笑之。且举世而誉之而不加劝，举世而非之而不加沮，定乎内外之分，辩乎荣辱之境，斯已矣。彼其于世未数数然也。虽然，犹有未树也。夫列子御风而行，泠然善也，旬有五日而后反。彼于致福者，未数数然也。此虽免乎行，犹有所待者也。若夫乘天地之正，而御六气之辩，以游无穷者，彼且恶乎待哉！故曰：至人无己，神人无功，圣人无名。
