　　解题方法

　　一、辨析词性

　　把十五个选项按词性分别归入名词、动词、形容词、副词等类别。

　　纵观样题和真题，我们知道15个词汇都属于最重要的四类实词。我们要学会每种词汇的基本搭配和基本用法。

　　辨性要注意下面几点。

　　1.遇到动词进行二次分类：确定时态，确定是第三人称单数还是非第三人称单数;但应注意动词+ed型的有两种可能性，动词或形容词;遇到名词要确定单数还是复数。

　　2.不认识的单词，看后缀。构词法中，前缀表明意思，后缀表明词性。所以看一个词的后缀，往往能大致分出词性。

　　3.词性一时无法确定的，暂时搁置，不必纠缠，影响全局。

　　4.作出相应的标记。可直接用自己最清楚的符号清楚标在每个词前后。不清楚的都标问号。

　　以真题为例辨词性

　　A) estimate; B) strength;

　　C) deliberately; D) notify;

　　E) tropical; F) phenomenon;

　　G) stable; H) attraction;

　　I) completely; J) destructive;

　　K) starvation; L) bringing;

　　M) exhaustion; N) worth;

　　O) Strike

　　名词：B,F,H,K,M

　　(B的后缀th, H、K、M的tion都是名词后缀)

　　谓语动词：A,D,O

　　(A的-ate极可能是动词，D的-fy为动词后缀)

　　非谓语动词：L(-ing结尾)

　　形容词：E, G, J

　　(E的-cal, G的able, J的tive是形容词后缀)

　　副词：C和I(ly加在形容词后为副词后缀)

　　注意：即使从没见过，也想办法看能否判断其词性，词的性质有时比词义还重要。词的性质并不总是固定的，有些不认识的或无法确定的，如N) worth (adj./n.)，可先搁置，不要过度纠缠。

　　大家可以在自己的备考过程中利用这个答题技巧找出答案，高效备考四级。
