第二节读写任务（共1小题，满分25分）

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

Every activity of our lives is communication of a sort, but it is through speech that man asserts his distinctness from other forms of life. He alone, of all animals, has the gift of verbal communication and it is through the quality of his speech that he best expresses his own individuality , his essence. When he is unable to say clearly what he means, through either nervousness, timidity, or foggy thought-processes, his personality is blocked off, dimmed out, and misunderstood.

Business, social, and personal satisfaction depend heavily upon a person’s ability to communicate clearly to his fellow men what he is, what he desires, and what he believes in. And now, as never before , in an atmosphere of international tensions, fears, and insecurities, we need the channels of communication between peoples kept open. It is my hope that The Quick and Easy Way to Effective Speaking will be helpful in all these ways, both to those who wish simply to function with greater ease and self-confidence in practical pursuits, and to those who wish to express themselves more completely as individuals seeking a deeper personal fulfillment.

--- Dorothy Carnegie，Introduction to The Quick and Easy Way to Effective Speaking
