1.Original: We know that sometimes success is measured by how much money you earn. Revised: It does not surprise us to discover that sometimes success is measured in terms of the money you earn.
专家点评:know是非常初级的词汇,作文中出现I believe that…,I know that…这样的表达只能体现考生写作技巧的稚嫩,用It does not surprise us to discover that…替换We know that…并没有改变原句的含义,却使全句顿时增添了亮点。
2.Original: We all know that most factories would be of no use if there were not clean water supply.
Revised: It goes without saying that most factories would be of no use if there were not clean water supply.
写作专家点评:同上例一样,know这样的初级词汇应避免在作文中使用,It goes without saying that…是一个固定结构,意思是“……是不言而喻的”,常在作文中用来引经据典或表明一个尽人皆知的道理
