一、避免使用语意弱的be动词。 1、把句中的表语转换为不同的修饰语。例如： Weak： The trees are bare. The grass is brown. The landscape seems drab. Revision：The brown grass and bare trees form a drab landscape. (转换为前置定语) Or： The landscape， bare and brown， begged for spring green. (转换为并列结构作后置定语) 2、将作表语用的形容词或名词变为行为动词。例如： 1) Weak： The team members are good players. Revision： The team members play well. 2) Weak： One workers plan is the elimination of tardiness. Revision： One workers plan eliminates tardiness. 3、在以here或there开头的句子中，把be动词后的名词代词变成改写句的主语。例如： 1) Weak： There is no opportunity for promotion. Revision： No opportunity for promotion exists. 2) Weak： Here are the books you ordered. Revision： The books you ordered have arrived. 二、多用语意具体的动词，保持句意简洁明了。例如： 1、Poor： My supervisor went past my desk. Better： My supervisor sauntered (=walked slowly) past my desk. 2、Poor： She is a careful shopper. |
