     For many in the United States,Arab-Americans are an invisible part of the population.

Though Arab-Americans as a community have made great contributions to American

society in fields from literature to politics to medicine,many Americans know very little

about Americans of Arab backgrounds．

     Arab history in the United States goes back to the late 1800's when large numbers

of Arab immigrants first began making their journey to a land known simply as"Amreeka"．

     Historians generally describe Arab immigration to America in two waves．The first wave

took place between 1860 and 1924．The first wave consisted of Lebanese and Syrian,and

some Egyptian immigrants．These new immigrants,who were mostly Christian,came to

America in search of better opportunities．Even the doomed Titanic,which set sail for

America in 1912,had close to a hundred Arab passengers aboard．The majority of

Arab-Americans today are descendents of the first wave of immigrants;they are the third

or more generation Americans．

     The second wave of immigrants followed after World War Ⅱ,caused by political unrest

in the Middle East．This second wave of immigrants consists of mainly Arab Muslims(穆斯

林)and continues to this day．

     Arab-Americans make up 3 million of the population in the United States,according to

demographers．And quite different from popular belief,64 percent of them are American-born．

Eighty-two percent of Arab-Americans are US citizens．

     Arab-Americans are beyond the national average in both education and income．Education

is important among Arab-Americans;82 percent have high school diplomas,36 percent have

bachelor's degrees or higher,and 15 percent have graduate degrees．The-median(中位数的)

average income among Arab-Americans is $39 580,which is higher than the US average．
