談詩歌鑒賞中的有效答題

顧葉斌

　　詩歌鑒賞題，答題時，考生往往是寫了很多，而得分卻很低。這是為什么呢？且來看一道題：讀李白的《子夜吳歌》，試分析兩首詩是如何表達思婦之情的？

子夜吳歌 秋歌
長安一片月，萬戶搗衣聲。
秋風吹不盡，總是玉關情。
何日平胡虜，良人罷遠征。

子夜吳歌 冬歌
明朝驛使發(fā)，一夜絮征袍。
素手抽針冷，那堪把剪刀。
裁縫寄遠道，幾日到臨洮？

　　綜觀考生的答案，典型的大致上有這么幾類情況：
　　【第一類】《秋歌》通過夜間的搗衣聲，通過秋風吹表達思婦之情，以動襯靜；《冬歌》通過一件征袍引發(fā)了思婦之情，運用想象。
　　【評析】這類考生思路混亂，將詩歌鑒賞中的的“表現手法”與“抒情方式”混淆了起來。《語文基礎知識手冊》中將“表現手法”與“抒情方式”同歸入藝術手法。其中凡是能使文章整體或部分產生鮮明強烈的印象，達到感染讀者藝術效果的手段或方法，都可以視為表現手法。如渲染、烘托、白描、鋪墊、照應、心理刻畫、蒙太奇、象征、用典、聯想、想象、托物起興、以動寫靜、以小見大、虛實結合、點面結合、寓莊于諧、借古諷今、欲揚先抑、明貶實褒、明褒實貶等手法。而抒情方式則分為直接抒情和間接抒情兩種。具體情況如下：
　　（1）直接抒情，也叫直抒胸臆，是一種不要任何“附著物”，而由作者直接對有關人物、事件等表明愛憎態(tài)度的抒情方式。如《鋤禾》：“鋤禾日當午，汗滴禾下土。誰知盤中餐，粒粒皆辛苦。”直接抒發(fā)了對糧食來之不易，應惜之的思想感情。
　�。�2）間接抒情。它包括借景（或借物）抒情、寓情于景（或物）和寓情于事。
　�、俳杈笆闱橐部山型形镅灾荆�如杜甫的《絕句》：“兩個黃鸝鳴翠柳，一行白鷺上青天。窗含西嶺千秋雪，門泊東吳萬里船�！比�詩寫景，描繪了山河的壯麗景象，表達了詩人對祖國的熱愛。在我國古代詩歌中，詩人常常把松、竹、梅、菊、柳、山石、溪流、沙漠、古道、邊關以及落日、夜月、清風、細雨、微草等作為借以抒情的對象。
　�、谠⑶橛诰埃ɑ蛭铮�。如柳永的《雨霖鈴》中：“今宵酒醒何處？楊柳岸曉風殘月。”
　�、墼⑶橛谑�，如李白的《早發(fā)白帝城》：“朝辭白帝彩云間，千里江陵一日還。兩岸猿聲啼不住，輕舟已過萬重山�！比�詩貌似敘事，可實則抒發(fā)了作者急于回家與家人團聚的迫切心情。
　　【第二類】《秋歌》通過間接地寫萬人搗衣的聲音、秋風來表達思婦之情，而《冬歌》通過直接地寫思婦為臨行前的丈夫縫征袍來寫思婦之情。
　　【評析】這類考生解題的思路倒是正確，把握住了從直接、間接角度來談抒情方式�？上Х治鲥e誤�！啊肚锔琛吠ㄟ^間接地寫萬人搗衣的聲音、秋風來表達思婦之情”表述不當。不是間接地寫“萬人搗衣的聲音、秋風”，是直接地寫“萬人搗衣的聲音、秋風”，間接地抒情。另外，“《冬歌》通過直接地寫思婦為臨行前的丈夫縫征袍來寫思婦之情”表述上也不當�！爸苯拥貙懰紜D為臨行前的丈夫縫征袍”，“直接”一詞用錯了地方，它不是問敘事，是問抒情方式“直接”還是“間接”。所以“直接”、“間接”應該用在對抒情方式的判定上。當然考生在表述上還有硬傷，“為臨行前的丈夫縫征袍”中“臨行前的”與原詩有很大的偏差。丈夫早就去了，現在“縫征袍”是給他寄過去。
　　【第三類】兩首都運用了間接抒情的方式。第一首《秋歌》是寓情于景，借景抒情的方式來表達的；第二首《冬歌》用了寓情于事的方式來表達的。
　　【評析】這一類考生答題思路正確，分析也基本正確，但也得不到全分。其弊端在于空洞，泛泛而談，沒有結合詩歌的內容來具體地談。
　　【第四類】《秋歌》寓情于景。“長安一片月”是景語，但又能引起思婦的情思；“萬戶搗衣聲”的特定的氛圍，極易促發(fā)思婦之情，吹不盡的“秋風”更能撩起思婦的愁緒�！昂稳掌胶�虜，良人罷遠征”直接表達了思婦對和平生活的向往之情。
　　《冬歌》寓情于事，通過寫趕在“明朝驛使發(fā)”之前“一夜絮征袍”以寄遠道的情事，來表達女子思念征夫的感情。
　　【評析】這一類考生答題思路清晰，分析正確，而且能聯系詩歌的內容來具體地談。這樣答才是有效答題，可以得滿分。
　　答題就像打靶。打靶不在于打了多少槍，關鍵在于是否打中了靶心。答題不在于寫了多少字，關鍵在于是否切中了采分點。有效答題對于考生尤為重要。

答案詳解：

1．A考生對本題的切入點是看到前后兩個句子所表達的意思是一樣的，所以可以肯定橫線部分是讓說話人重復一遍，A項符合題意。

2．C本題的關鍵是看到后半個分旬帶有轉折的意思，故前半分句的意思是“我本來希望我明天可以離開�！敝挥蠧項表示“原來希望”。

3．D本題是情態(tài)動詞的考查。首先肯定對前半部分是否定的，而mustn't表示禁止，與題意不符。dare可以作情態(tài)動詞，也可以作實義動詞。

4．B本題是名詞性從句的考查。that引導she was invited to the ball的從句作為整個句子的主語。

5．D本題是連詞的辨析使用。as表示“隨著”，通常表示前后動作發(fā)生的時間為一致的。when強調在一個動作發(fā)生過程中另一個事情突然發(fā)生。while表示兩個同時進行的持續(xù)性動作，且強調主句表示的動作延續(xù)到從句所指的整個時間。

6．D to make matters worse是固定用法，在本題中充當插入語。   

7．C本題考查冠詞的用法。前一個空over the telephone表示“通過電話”；by letter表示“通過寫信”，by表示方式后直接接一個名詞。

8．A本題考查狀語從句的用法�？忌�一上來不能為“，”所迷惑，立刻選擇了D項which。這里where引導一個狀語從句。

9．C本題是對副詞的考查。關鍵是理解情景對話的含義。整道題的意思是：“你今天看上去氣色不好。怎么了?”“我感冒了，但是不嚴重�！彼�以C項符合題意。

10．B本題考查形容詞的次序排列�？忌�解題的關鍵是掌握所修飾的名詞前必須緊接質地或性質的詞，故排除C、D。few與后面的詞關系更為密切，所以放在short前面。

11．B本題考查介詞的用法。表示以多少價格賣掉某物用介詞for。

12．D本題是情景對話的考查�？忌�的關鍵是抓住I’ll keep none．none說明所拿走的東西至少有三個，而且可以全部拿走，所以選D。

13．A本題考查動詞詞組的辨析。A項意為“扔掉，丟失”；B項意為“放下”；C項意為“向……屈服”。

14．A本題只要考生理解了情景對話的含義，是不難得出答案的。A項顯然是符合題意的。

15．A本題考查非謂語動詞的使用。to save在句中表示“為了節(jié)省”。

16．A本題是有關花費的幾個詞的辨析�？忌�很可能選擇B，但一定要注意問句中的謂語動詞是is，所以可以排除cost。be worth+價格可以表示花費多少錢。

17．C本題是情景對話的考查。A應為So am I。D項常用于祝福語或問候語的回答。

18．D本題是動詞的時態(tài)考查。答句的意思是：“當你掌握一些技巧時你就可以了�！�

19．B本題考查賓語從句的使用。whatever引導了一個賓語從旬，意思是：不管他(她)想要什么。

20．A  本題是對冠詞的考查。兩個空格都是泛指，所以選用不定冠詞a。

21．B本題仍是考查時態(tài)的用法。run out是指用完。由于受到后面句子中before I’ve none in hand的限制，表明錢還沒用完。

22．B quite a few指的是許多。后面空格that替代前面的單詞advice。

23．C hardly在句首，主句要倒裝，故可以排除其他三項。

24．C本題考查動詞的用法。首先理解句子的意思：“漫長的旅途中，彼特被證明是一個很有趣的導游。我們都玩得很開心�！眕rove后接to be+形容詞，to be可以省略。

25．A本題是副詞用法的考查。句子的意思是：“你和吉姆住得近嗎?”“不，他住在城市的別處。”故A項符合題意。

26．C本題考查狀語從句的知識。where引導一個狀語從句。

27．C本題是省略的使用。考生可以恢復原句：Some of the suspects(who were)questioned refused to answer and kept their mouths shut．

28．C本題是倒裝句的考查。注意little是否定詞，所以反意疑問用肯定。

29．B本題是固定用法的考查。too／quite…+形容詞+a／an+名詞是固定的結構用法。

30．B本題是副詞位置和動詞時態(tài)的考查。be always doing表示總是干什么
