1. Needy贫穷的
讲解：说到“贫穷的”很多学生头脑里只能冒出来“poor”这个词。但是如果大家常看BBC等地道英文，会总结出很多表示“贫穷的”说法。比如“impoverished”请看例句：
The previously free distribution of text books will now be confined to students who are needy.以前免费发放课本，现在只给贫困学生。
(注：needy主要用以描述群体，不用以描述自己或个人)
They were impoverished by a prolonged spell of unemployment.他们因长期失业而一贫如洗。
(注：impoverished尤用于新闻，指贫困国家和生活在贫困国家的人。富裕国家的贫困地区用deprived)
Poverty-stricken指赤贫的，一贫如洗的，如：a poverty-stricken family in 19thcentury Brooklyn19世纪布鲁克林区一个赤贫家庭
2. Go to the wall破产
讲解：BBC NEWS有关中国奶粉丑闻报道曾经用过这个短语。(Chinese milk powder are stymied, and scores of dairy firms have gone to the wall.)大家都知道的一个表示破产的形容词是 “bankrupt”。请看例句：
The firm will soon go to the wall.该公司马上就要破产了。
He bought up a bankrupt textile company.他买下了一家破产的纺织公司。
The company went bankrupt.那家公司破产了。
3. Disseminate传播
讲解：我们在写文章时，经常会用到“传播”这个动词比如传播信息，知识等。我们可以用“spread”替换“disseminate”。

The government has a responsibility of disseminating information about disease prevention.政府有责任传播疾病预防的信息。

6. Self-made

He was proud of the fact that he was a self-made man.他为自己白手起家而自豪。
