谈诗歌鉴赏中的有效答题

顾叶斌

　　诗歌鉴赏题，答题时，考生往往是写了很多，而得分却很低。这是为什么呢？且来看一道题：读李白的《子夜吴歌》，试分析两首诗是如何表达思妇之情的？

子夜吴歌 秋歌
长安一片月，万户捣衣声。
秋风吹不尽，总是玉关情。
何日平胡虏，良人罢远征。

子夜吴歌 冬歌
明朝驿使发，一夜絮征袍。
素手抽针冷，那堪把剪刀。
裁缝寄远道，几日到临洮？

　　综观考生的答案，典型的大致上有这么几类情况：
　　【第一类】《秋歌》通过夜间的捣衣声，通过秋风吹表达思妇之情，以动衬静；《冬歌》通过一件征袍引发了思妇之情，运用想象。
　　【评析】这类考生思路混乱，将诗歌鉴赏中的的“表现手法”与“抒情方式”混淆了起来。《语文基础知识手册》中将“表现手法”与“抒情方式”同归入艺术手法。其中凡是能使文章整体或部分产生鲜明强烈的印象，达到感染读者艺术效果的手段或方法，都可以视为表现手法。如渲染、烘托、白描、铺垫、照应、心理刻画、蒙太奇、象征、用典、联想、想象、托物起兴、以动写静、以小见大、虚实结合、点面结合、寓庄于谐、借古讽今、欲扬先抑、明贬实褒、明褒实贬等手法。而抒情方式则分为直接抒情和间接抒情两种。具体情况如下：
　　（1）直接抒情，也叫直抒胸臆，是一种不要任何“附着物”，而由作者直接对有关人物、事件等表明爱憎态度的抒情方式。如《锄禾》：“锄禾日当午，汗滴禾下土。谁知盘中餐，粒粒皆辛苦。”直接抒发了对粮食来之不易，应惜之的思想感情。
　　（2）间接抒情。它包括借景（或借物）抒情、寓情于景（或物）和寓情于事。
　　①借景抒情也可叫托物言志，如杜甫的《绝句》：“两个黄鹂鸣翠柳，一行白鹭上青天。窗含西岭千秋雪，门泊东吴万里船。”全诗写景，描绘了山河的壮丽景象，表达了诗人对祖国的热爱。在我国古代诗歌中，诗人常常把松、竹、梅、菊、柳、山石、溪流、沙漠、古道、边关以及落日、夜月、清风、细雨、微草等作为借以抒情的对象。
　　②寓情于景（或物）。如柳永的《雨霖铃》中：“今宵酒醒何处？杨柳岸晓风残月。”
　　③寓情于事，如李白的《早发白帝城》：“朝辞白帝彩云间，千里江陵一日还。两岸猿声啼不住，轻舟已过万重山。”全诗貌似叙事，可实则抒发了作者急于回家与家人团聚的迫切心情。
　　【第二类】《秋歌》通过间接地写万人捣衣的声音、秋风来表达思妇之情，而《冬歌》通过直接地写思妇为临行前的丈夫缝征袍来写思妇之情。
　　【评析】这类考生解题的思路倒是正确，把握住了从直接、间接角度来谈抒情方式。可惜分析错误。“《秋歌》通过间接地写万人捣衣的声音、秋风来表达思妇之情”表述不当。不是间接地写“万人捣衣的声音、秋风”，是直接地写“万人捣衣的声音、秋风”，间接地抒情。另外，“《冬歌》通过直接地写思妇为临行前的丈夫缝征袍来写思妇之情”表述上也不当。“直接地写思妇为临行前的丈夫缝征袍”，“直接”一词用错了地方，它不是问叙事，是问抒情方式“直接”还是“间接”。所以“直接”、“间接”应该用在对抒情方式的判定上。当然考生在表述上还有硬伤，“为临行前的丈夫缝征袍”中“临行前的”与原诗有很大的偏差。丈夫早就去了，现在“缝征袍”是给他寄过去。
　　【第三类】两首都运用了间接抒情的方式。第一首《秋歌》是寓情于景，借景抒情的方式来表达的；第二首《冬歌》用了寓情于事的方式来表达的。
　　【评析】这一类考生答题思路正确，分析也基本正确，但也得不到全分。其弊端在于空洞，泛泛而谈，没有结合诗歌的内容来具体地谈。
　　【第四类】《秋歌》寓情于景。“长安一片月”是景语，但又能引起思妇的情思；“万户捣衣声”的特定的氛围，极易促发思妇之情，吹不尽的“秋风”更能撩起思妇的愁绪。“何日平胡虏，良人罢远征”直接表达了思妇对和平生活的向往之情。
　　《冬歌》寓情于事，通过写赶在“明朝驿使发”之前“一夜絮征袍”以寄远道的情事，来表达女子思念征夫的感情。
　　【评析】这一类考生答题思路清晰，分析正确，而且能联系诗歌的内容来具体地谈。这样答才是有效答题，可以得满分。
　　答题就像打靶。打靶不在于打了多少枪，关键在于是否打中了靶心。答题不在于写了多少字，关键在于是否切中了采分点。有效答题对于考生尤为重要。

答案详解：

1．A考生对本题的切入点是看到前后两个句子所表达的意思是一样的，所以可以肯定横线部分是让说话人重复一遍，A项符合题意。

2．C本题的关键是看到后半个分旬带有转折的意思，故前半分句的意思是“我本来希望我明天可以离开。”只有C项表示“原来希望”。

3．D本题是情态动词的考查。首先肯定对前半部分是否定的，而mustn't表示禁止，与题意不符。dare可以作情态动词，也可以作实义动词。

4．B本题是名词性从句的考查。that引导she was invited to the ball的从句作为整个句子的主语。

5．D本题是连词的辨析使用。as表示“随着”，通常表示前后动作发生的时间为一致的。when强调在一个动作发生过程中另一个事情突然发生。while表示两个同时进行的持续性动作，且强调主句表示的动作延续到从句所指的整个时间。

6．D to make matters worse是固定用法，在本题中充当插入语。   

7．C本题考查冠词的用法。前一个空over the telephone表示“通过电话”；by letter表示“通过写信”，by表示方式后直接接一个名词。

8．A本题考查状语从句的用法。考生一上来不能为“，”所迷惑，立刻选择了D项which。这里where引导一个状语从句。

9．C本题是对副词的考查。关键是理解情景对话的含义。整道题的意思是：“你今天看上去气色不好。怎么了?”“我感冒了，但是不严重。”所以C项符合题意。

10．B本题考查形容词的次序排列。考生解题的关键是掌握所修饰的名词前必须紧接质地或性质的词，故排除C、D。few与后面的词关系更为密切，所以放在short前面。

11．B本题考查介词的用法。表示以多少价格卖掉某物用介词for。

12．D本题是情景对话的考查。考生的关键是抓住I’ll keep none．none说明所拿走的东西至少有三个，而且可以全部拿走，所以选D。

13．A本题考查动词词组的辨析。A项意为“扔掉，丢失”；B项意为“放下”；C项意为“向……屈服”。

14．A本题只要考生理解了情景对话的含义，是不难得出答案的。A项显然是符合题意的。

15．A本题考查非谓语动词的使用。to save在句中表示“为了节省”。

16．A本题是有关花费的几个词的辨析。考生很可能选择B，但一定要注意问句中的谓语动词是is，所以可以排除cost。be worth+价格可以表示花费多少钱。

17．C本题是情景对话的考查。A应为So am I。D项常用于祝福语或问候语的回答。

18．D本题是动词的时态考查。答句的意思是：“当你掌握一些技巧时你就可以了。”

19．B本题考查宾语从句的使用。whatever引导了一个宾语从旬，意思是：不管他(她)想要什么。

20．A  本题是对冠词的考查。两个空格都是泛指，所以选用不定冠词a。

21．B本题仍是考查时态的用法。run out是指用完。由于受到后面句子中before I’ve none in hand的限制，表明钱还没用完。

22．B quite a few指的是许多。后面空格that替代前面的单词advice。

23．C hardly在句首，主句要倒装，故可以排除其他三项。

24．C本题考查动词的用法。首先理解句子的意思：“漫长的旅途中，彼特被证明是一个很有趣的导游。我们都玩得很开心。”prove后接to be+形容词，to be可以省略。

25．A本题是副词用法的考查。句子的意思是：“你和吉姆住得近吗?”“不，他住在城市的别处。”故A项符合题意。

26．C本题考查状语从句的知识。where引导一个状语从句。

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

28．C本题是倒装句的考查。注意little是否定词，所以反意疑问用肯定。

29．B本题是固定用法的考查。too／quite…+形容词+a／an+名词是固定的结构用法。

30．B本题是副词位置和动词时态的考查。be always doing表示总是干什么
