While sentence 9B shows the relation clearly without using subordinate clauses which will be helpful to the reader’s understanding. By paring these two examples, we can say sentence 9B will actually save reader’s time and more briefly to send information.(4) To be orderly。The whole letter should focus on the subject and achieves the purpose step by step.10) We are very pleased to receive your inquiry of 5th Jan. and enclose our illustrated catalogue and price list giving the details you ask for.

In this way, his point stands out clearly and orderly which can improve the munication.4. Case Study of Business Letter.

The Cooperative Principle in the Case. In this letter, by using the four maxims of cooperative principle to evaluate whether it has achieved its purpose or not when it was written, we can conclude that it basically plies with cooperative principle and shows its point clearly.
