概述
在報紙、雜誌或電視媒體中，常常有專家學者或權威人士拋出自己的觀點，而大多數人對此深信不疑，但權威並不是永遠正確的。在社會生活中，許多人由於盲目相信權威而導致了一係列不良後果，有人甚至利用權威來謀求個人利益。鑒於此，懷疑精神就顯得尤為重要了。
一、寫作思路
首段：可以通過名人名言引出懷疑精神的重要性，如懷疑是獲得知識的關鍵；然後對這句名言進行解釋，即用生活中的現象來說明這句話的內涵。
中段：可以選擇盲目相信權威這一話題開頭。首先可以列舉哲學家、科學家或教育家的例子，他們對社會發展做出了貢獻，也傳播和創造了新知識、新技術等。然後通過轉折來說明專家也是人，也會犯錯，而知識是經驗的總結，因此知識也不見得總是正確的。所以，人們需要有懷疑的精神，做出自己的判斷，這樣才能得到真正的知識。
末段：強調個人對於懷疑精神的提倡：雖然在懷疑的過程中可能有痛苦，甚至會有來自他人的誤解，但是懷疑精神的重要性不可忽視。
二、參考範文和譯文
參考範文
The Spirit of Doubt
Someone once said: doubt is the key to acquiring knowledge. This famous sayingis conveying the idea that the true acquisition of knowledge lies not merely inpassing down knowledge from ancestors or teachers, but also in the use of yourown judgment. Our society is surrounded by comments or criticisms fromauthorities which are not evaluated in a spirit of doubt. Doubt is essential toacquiring truth and developing as a person and society.
Blindly trusting
Authority has been a part of human nature since the dawn ofcivilization. Admittedly, some authorities, particularly philosophers,scientists and educators, have made enormous contributions to the developmentand spread of knowledge. People have benefited from this. But what cannot bedenied is that knowledge is connected to personal experience. People makemistakes. As long as people are involved, mistakes are likely to appear in allaspects of getting and spreading knowledge. Thus, we must look at knowledge witha spirit of doubt and make our own judgments. Only in this way can trueknowledge be acquired.
