     The campaign is over. The celebrations have ended. And the work for US president-elect Barack Obama

has begun.

     The 47-year-old politician rose to the highest post because of his stand against the war in Iraq and his plans

to fix a weak economy. But what will the first 47-year-old African-American president do for race relations?

     Obama's victory appears to have given blacks and other minorities a true national role model. For years,

many looked to athletes and musicians for inspiration. As Darius Turner, an African-American high school

student in Los Angeles, told the Los Angeles Times, "Kobe doesn't have to be everybody's role model

anymore."

     Recent polls (民意测验) also suggest that Obama's victory has given Americans new optimism about race

relations. For example, a USA Today poll found that two-thirds of Americans believe relations between blacks

and whites "will finally be worked out". This is the most hopeful response since the question was first asked

during the civil rights revolution in 1963.

     However, it's still too early to tell whether Obama's presidency will begin to solve many of the social problems facing low-income black communities.

     Although blacks make up only 13 percent of the US population, 55 percent of all prisoners are

African-American. Such numbers can be blamed on any number of factors on America's racist past, a failure

of government policy and the collapse (瓦解) of the family unit in black communities.

     It is unlikely that Obama will be able to reverse (扭转) such trends overnight. However, Bill Bank, an expert

of African-American Studies, says that eventually young blacks need to find role models in their own

communities."That's not Martin Luther King, and not Barack Obama," he told the Los Angeles Times."It's

actually the people closest to them. Barack only has so much influence."

      In the opinion of black British politician Trevor Phillips, Obama's rise will contribute more to

multiculturalism than to race relations in the US.

      "When the G8 meets, the four most important people in the room will be the president of China, the prime

minister of India, the prime minister of Japan and Barak Obama," he told London's The Times newspaper."It

will be the first time we've seen that on our television screens. That will be a huge psychological shift (心理转变) for both the white people and the colored ones in the world."

案例三：一般资料：求助者，女性，45岁，个体老板。案例介绍：求助者的儿子患有先天性心脏病，十多年来她把大部分的时间和金钱都用在了为儿子看病上。她认为儿子患病是由于自己年轻无知，怀孕期间吃药造成的，为此一直自责，异常痛苦。有一次儿子生病，半夜到急诊室就诊，当时医护人员正在抢救一位心脏病病人，忙不过来。求助者当时又急、又累，突然觉得透不过气来，胸闷、心慌，非常难受，觉得自己也得了心脏病。因此非常紧张、害怕，浑身颤抖，呼吸急促，心跳加快，当即晕倒在急诊室，经诊治后症状缓解。后来又有类似症状发生，住院检查，未查出明显器质性病变。此后经常发作，每周大约3—4次，时间持续数十分钟。发作时无特定时间地点场合，也无明显发作征兆，可自行缓解。多次到医院就诊，服用过镇静类药物，但仍时有发作。发作时头脑清醒，不发作时，生活、工作大致正常。目前求助者不敢一个人外出、一个人独处，怕自己突发心脏病死了。知道自己不一定患心脏病，但没法控制。情绪低落，曾对家人表示这样活着真是受罪，还不如死了。 心理咨询师观察了解到的情况：求助者身体健康，性格较内向，对自己要求很严格，做事认真谨慎。对孩子照顾得无微不至，把孩子看成自己的生命。

单选：对该求助者的初步诊断是()。
