31、(估计)组合成的新单词，它的意思是：高估。(2)派生法。派生法是通过在基础根上添加前缀或者后缀来构造新词。一般来说，前缀改变词义不改变词性，而后缀改变词性不改变词义。常见的前缀有：表示否定或者相反意思的前缀dis， un， im， in， ir， il， non， mis等用在单词的前面，往往构成原单词的反义词。如：correctincorrect, legalillegal, likeunlike等。表示“又，再，重新” 的前缀re，如：rebuild重建，reapply重新申请。表示“和一起，共同”的前缀co，如：coworker同事，合作者。表示“过于”的前缀over，如overuse使用过度，overjoyed欣喜若狂。表示“超级，极”的前缀super，如：supermarket超级市场，superpower超级大国。例如上文C篇阅读中第11小题，eco是个前缀，意为“环境的，生态的”，ecofriendly的表面意思是“对生态环境友好的”，也就是“有益于生态环境的”。(3)转化法。把一种词性用作另一种词性而词形不变的方法叫作转化法。如：“He insisted on staying up to nurse the child.”中的nurse原为名词“护士”，转化为动词“护理，看护”。
