A garden of poems（Reference for Teaching）

      immediately after the second world war, britain looked like a prosperous and friendly country for an immigrant worker. all commonwealth citizens were free to enter the country and look for work, which was plentiful. however, since the immigration act of1962, successive governments have introduced regulations to restrict the number of immigrants.
      it is difficult to get statistics on race, but the following patterns are clear. the percentage of nonwhites in britain increased quite rapidly between 1945 and the end of the1970s. at present, more than half the nonwhites in britain are immigrants, but it will soon be the case that the majority of nonwhites are people born in britain.
      ethnic minoritie are concentrated in the cities. the percentage of members of ethnic minorties who are unemployed, or in lowgrade jobs, is higher than in the population as a whole.
      racial discrimination and poor living conditions have contributed to racial violence, especially in the day-to-day form of relations between young blacks and the police, or in the more extreme from of inner-city riots. this is despite the race relations act (1976), which was designed to promote equality of opportunity for people of all races.
