使用简洁的词来代替冗长累赘的短语

　　例（１０）：Wordy: In the sense of his speech he talked on the question of securities.

　　Concise: During his speech he talked about securities.

　　例（１１）Wordy: During the proceeding year, the company was able to accelerate productive operations.

　　Concise: Last year, the company was able to accelerate productive operations.

　　例（１０）和例（１１）中wordy的句子里In the sense of 可以用During来代替，同为＂在．．．里＂的意思；on the question of 可以用about来替代，同为＂有关．．．，关于．．．＂同理,例（１１）中wordy的句子里的During the proceeding year也可以用Last year来代替。没有改变原来句子要表达的意思，而且显得更加简洁，更加直白，在口语中更加常用。会使得读信人更加容易理解。既然如此，商务信函写作者为什么不用这些简洁、明了、清晰的常用词来代替那些冗长、累赘、空洞的短语呢？
