    阅读下面短文并回答问题，然后将答案写到答题卡相应的位置上（请注意问题后的词数要求）。
    【1】The air was pleasant and the music was loud in the vast square in front of the New York State office building in Harlem(哈莱姆，美国纽约市黑人居住区) as health advocates（支持者，提倡者） set up information tables for Harlem wellness Week. It was a wide-ranging effort to educate people about non-communicable diseases: Heart disease, cancer, lung disease, obesity, and so on.
    【2】There is an economic effect caused by these diseases, especially in Harlem, one of the city’s poorest districts. Without healthy employees and healthy customers, you cannot have healthy business, says Patricia Ricketts of the Greater Harlem Chamber of Commerce, which sponsors Wellness Week.
    【3】Dr. Jo Ivy Boufford is president of the New York Academy of Medicine, a Wellness Week partner. She says education about better nutrition is important, but that people with low incomes often lack the means to put what they know into practice. But there is hope. New York is very active in advocating good, effective public health policies. “New York City has banned smoking in public places, both indoors and outdoors. That is a fantastic example of what can be done, without having any impact on the economy. It is a city where you have bike paths. That is a good message for the world, because bikes make your transport active. That is good for your health and lowers air pollution,” she said.
    【4】“It is not enough to focus on the management of disease through medication,” Dr. Boufford says. “That’s why health advocates will be trying to persuade UN officials during Wellness Week to pass resolutions that deal with road and transport design and construction and other potential causes of non-communicable diseases.”
