Revision
Why is California in the 21st century such a multicultural community?
1. The Native→ native Americans of California are continuing to heal from the wounds of the past. As California recognizes the value of its multi-ethnic diversity, its native people are encouraged to celebrate their heritage and share it with the wider California culture.
2. The number of African Americans in California increased dramatically following the turn of the 20th century. Although old patterns of prejudice persisted, Africans Americans advanced in politics, business, sports and entertainment. School segregation and
discrimination in housing were banned, but problems of unemployment, underemployment and racism continue to be addressed in the African American community.
3. By 1990, the number of European and Canadian immigrants had fallen dramatically, to less than 10 percent, and the number of immigrants from Mexico and Central America had climbed to well over half of the total.
4. Additionally, California's share of Asian immigrants doubled and now accounts for 40 percent of new immigrants in the state.
Suffixation 后缀
A suffix is a particle, which is added to the end of a root. Suffixes do not change the meaning of the root, but its part of speech.
e.g. lead (v.)→ leadership (n.)
ill (adj.)→ illness (n.)
Although each suffix has its own meaning, it can’t be used separately without the root.　　
However, some suffixes add new meanings to the newly formed words.
e.g. meaning → meaningless
think → thinker
