1．懸念法懸念法又稱關(guān)子。它是作者為了激發(fā)那種“緊張與期待的心理活動”，在行文中有意采取的一種積極而有效的手段。這種手段包括“設(shè)懸”和“解懸”兩方面。所謂 “設(shè)懸”就是設(shè)置懸念，即在情節(jié)發(fā)生發(fā)展的關(guān)鍵時刻或人物命運攸關(guān)的重要關(guān)頭，敘述戛然而止，轉(zhuǎn)敘他事。從而引起讀者強烈的尋根問底的興趣。所謂“解懸” 也叫“釋懸”，就是指在情節(jié)發(fā)展的特定階段，通過矛盾的解決，揭示事情原委和人物命運的結(jié)局，使讀者的期待心理得以滿足。如《驛路梨花》，當人們正為露宿而發(fā)愁時出現(xiàn)了一間神秘的小屋，小屋的主人是誰呢？猜想間，有人來了，但也不是屋子主人，那小屋子的主人是誰呢？終于知道了小屋是解放軍蓋的，但為什么要蓋這間小屋呢？這樣“設(shè)懸——釋懸——帶出新懸念”，環(huán)環(huán)相扣、層層遞進，使文章韻味無窮。

①闡發(fā)話題式:就是用簡練的語言對所給話題材料加以概括和濃縮，并找到一個最佳切入點加以深層次闡述。吉林一考生的滿分作文《漫談“感情”“認知”》的題記是：“同是對‘修墻’‘防盜’的預(yù)見，卻產(chǎn)生‘聰明’或‘被懷疑’的結(jié)果。‘感情’竟能如此地左右著‘認知’，心的小舟啊，在文化的河流中求索?！边@個題記通過對材料的簡單解釋，將“感情”與“認知”二者的關(guān)系詮釋得非常明白，也點明了作者的態(tài)度和議論的中心。②詮釋題目式:所擬題目一般都具有深刻性特點，運用題記形式對題目進行巧妙而又全面的詮釋。云南一考生的滿分作文《與你同行》的題記是：“他們一路同行，一個汲著水，一個負著火，形影相隨。在他們攜手共進時，就產(chǎn)生了智慧。”這個題記形象而深刻地對“與你同行”這個題目進行了解釋，言簡意賅，表明了考生對感情和理智關(guān)系的認識。
