The chosen area was theHarlem which Blacks were moving in the first decades of the 2.________ new century as they left their old settlements on the middle and lower blocks of the West Side.As the community became predominantly Black, the very worHarlem seemed to lose its old meaning. At time it was 3.________ easy to forget that Harlemwas originally the people from Holland;and that for most of its three centuriesit was first settled in the sixteen hundredsit had been preoccupied

5.________ by White New Yorkers. Harlembecame synonymous to

6.________ Black life and Black style in Manhattan. Blacks living there used the word as though they had coined it on themselvesnot

7.________ only to designate their area of residence but to express their sense of the various qualities of its life and atmosphere. As the years passed, Harlemasserted an even larger meaning. In

8.________ the words of Adam Clayton Powell, Sr., the pastor of the Abyssinian Baptist Church, Harlem became the symbol of liberty and the Promised Land to Negroes everywhere.

By 1919 Harlems population had grown by several thousand. It had received its share of wartime migration from the South, the Caribbean, and parts of colonial Africa. Some of the new arrivals

merely lived for Harlem; it was New York they had 9.________ come to, looking for jobs and for all the other legendary opportunities of life in the city. To others who migrated to Harlem, New York was merely the city in which they found themselves: Harlem was exactly what they wished to be. 10.________答案1. want wanting?

该句的谓语动词在破折号之后，即designate，因此有必要将前一动词变成分词形式。

2. Harlem which to?

黑人们搬进了Harlem，因此这里Harlem是先行词，关系代词应当表示地点，即可以是where，也可以是介词+which的形式。

?3. time times?

at a time是一次的意思，而at times是时而，偶尔的意思。?

4.Harlem; the community that?forget后面引导的是三个宾语从句，在这种情况下，that通常不能省略。

5.preoccupied occupied?

be preoccupied with sth.指忙于某事。occupy是占领之意。

6.to with?

by synonymous with是与等同与意义相同的意思,与synonymous搭配的是介词with。

7.on /?

by themselves或on their own都表示他们自己的意思，coin

是创造之意。?

8.asserted assumed? assert是肯定，断定，assume指开始具有某种(品质或形象等)，强调的是一个从无到有的发展过程。?

9.for in?

由下文it was New York they had come to可知这些人并非是为Harlem而活着，因为他们的目标是整个纽约城，他们只是居住在Harlem罢了。?

10.what where?本段中Harlem还是作为一个地区名存在，相关的思想意义并不多。
