[单项选择]Once a man had a dream, he dreamed of a land of peace and harmony. He dreamed of a place where people were not judged by their skin color. He dreamed of a country where children of different races could play together. He dreamed of a nation where all people were equal. Some people didn’t like his dream. They said it would never happen. Some people applauded his dream. They wanted to make it happen. This noble vision has come true for some. For others, it’s still just a fantasy.
In 1963, this man, Dr. Martin Luther King Jr. , expressed his vision in the famous speech, "I Have a Dream." But the dream -- rooted in the American Dream -- wasn’t really new. From the beginning, this nation of immigrants welcomed people desiring freedom and a new start. How ever, the coming together of different races and ethnic groups created some tensions. The early Americans ( except for the native "Indians" ) were almost all white Europeans. As more immigrants arrived, European groups fit into society

There are two main methods
of organizing governments —the unitary system and the federal system. The
unitary state places most power in the hands of central government officials,

states whose boundaries coincide closely with the boundaries of nations are more
likely to consider a unitary system of government. In addition, because the
unitary system requires effective communications with all regions of the
country, smaller states are more likely to adopt it. If the country is very
large or has isolated regions, strong national control is di
A. Only small countries adopt the unitary system.
B. Unitary states all have uniform culture.
C. Multinational states can be unitary states.
D. The federal system is more suitable for communist states.
