关于词汇问题（Vocabu1ary）
        3. 利用文章中对词的定义猜测词义
        Example：
        Such experiences are not unusual for the amateur conchologists, people who collect shells.
        Conchologists的意思可以根据该词后面的同位解释people who collect shells 理解为收集贝壳的人或贝壳收藏家。
        
        Example :
        Jack is now a florist, who keeps a shop for selling flowers in our district.
        florist 的意思就是其后定语从句who keeps a shop for selling flowers 所描述的拥有一家专门卖花的商店的人，即花店主.。
        
        4. 利用文章中对词的举例及解释猜测词义
        Example :
        Today young couples who are just starting their households often spend lots of their money on appliances ,for instance ,washing machines , refrigerators and color TVs.
        
        通过所举的例子（washing machines ,refrigerators and color TVs）
        可以看出，appliances 应是这些名词的总称，即家用电器。
        Example :
        Finally the enemy surrendered. They threw down their weapons and walked out of the home with their hands over their heads.
        通过后一句对surrendered的解释：扔掉武器（throw down their weapons ），举起双手（with their hands over heads ）可知其意是投降。
        
        5. 利用构词法知识（前缀和后缀）猜测词义
        Example :
        They overestimate the interviewee’s ability and asked him many difficult questions.
        estimate是估计的意思，over－是前缀，意为过分，过度，超过等，因此overestimate就是高估的意思。
        
        Example :
        We were told that ours was the most spacious room in the hotel. That was why we had to pay so much for it.
        spacious是由space(名词，空间)＋－ious(形容词后缀）变化而来的，因此，可猜测其词义为宽敞。
        　　
        各种各样的前、后缀可以构成名词、形容词、动词、副词等，这些词缀需要平时不断地积累和记忆。掌握构词法知识是扩大词汇量和猜测生词词义的最佳办法。转贴于 考试大 http://www.examda.com
