The per capita income reached 5,318 yuan (8.27 yuan against US dollar) in 2002. Yet some households in the county are still living in poverty. To get them rid of poverty, the county government has launched a poverty alleviation project, which has involved some 160 government institntions, enterprises, schools and other units. An official review on the project last year found that good results had been achieved in poverty alleviation. In 2002 alone, 199 households had been helped to shake off the poverty and move towards a relatively comfortable life.展开更多

文摘我们知道英语习语(English Idiom)有两个基本特征:一是语义的统一性(Semantic Unity)即应从整体上去揣测词义;一是结构的固定性(Structural Stability),即各组成部分是固定的,对于英语的习语切不可望文生义,更不可一锤定音:有些习语(特别是动词性习语Verbal Idiom)由于某些用法特点的不同,从而决定其语义的复杂性,对于do with这个习语大家并不陌生,但要真正彻底理解它的意义决非有的人想象的那么简单,把What are youdoing with that gun?中的do with理解为“对付、处理”固然没有望文生义,却也未见得就理解了这句话的真正含义。笔者想借此机会谈谈怎样确切理解和更好掌握do with的含义和用法。
