    在1898年馬建忠撰寫的第一部漢語語法專著《馬氏文通》問世到現在的一百多年裡，語法教學在中學語文學科中的地位始終沒有確定下來， 「淡化」甚至「取消」語法教學的觀點時而浮現于語文教學的理論與實踐中。問題的癥結何在?筆者通過定量與定性分析，現實調查與理論探討相結合，認為中學語法教學的主要癥結在於：中學語法教學確立的目標脫離廣大師生的教情與學情實際；中學語法內容體系來源於語法研究成果，而語法研究中存在著諸多弊端，從而直接或間接地影響著中學語法教學；人們對中學語法教學目的的認識也有一個不斷趨向科學的過程：語法教材也存在著內容及編排的局限性? ?中學語法教材的依據語法體系本身具有局限性，語文教材中的語法的內容與編排也具有一定的局限性，諸如沒有遵循學生的認識規律，高中沒有語法教學的內容和要求，語法初中沒有過關，高中則更趨回生等；再者，教師素質及教學方法不適應，沒有把靜態的語法教學與動態的語法教學結合起來，忽視了教學語法的實用性的特點；長期以來，中學語法教學的意義定位不準，不是偏高就是偏低等等，由此，筆者得出結論：由於上述問題的存在，導致了「語法無用」進而要求「淡化語法」甚至「取消語法」論調的產生，而並非語法知識本身無用，因此，今後語法教學改革的方向是解決這些問題，而不是淡化和取消。
