英语四级写作高分训练月计划第三周：星期四（6）

　　六、学会使用介词短语
　　英语中有很多介词短语都具有动词的特征，适合表达抽象的含义。学会活用这些介词不但可以丰富文章的用词，而且能够增强文章的表现力。另外，我们经常可以用介词短语代替从句，从而使语言表达更加简洁有力。

　　如：
　　原句：His farmily obviously cannot afford the big sum of money for such an operation obviously .
　　优化：The big sum of money for such an poeration is obviously beyond what his family can afford .
　　原句：pirated products often cost much less than the original ones , so they enjoy unbeatable advantage in price though their quality is relatively poor .
　　优化：Pirated products often cost much less than the original ones , so they enjoy unbeatable advantage in price despite their relatively poor quality .
