29、noon, sportsman, blackboard, sportsperson, newspaper, airplane, classmate, grandfather 等就是通过合成构词法构成的名词；kind-hearted, middle-aged, hard-working 等为合成形容词；however, maybe, himself, everyone, nothing, overlook 等也都是通过合成法构成的单词。2. 派生法通过在词根前面加前缀或在词根后面加后缀构成一个新词的方法叫作派生法。要通过派生法理解和记忆单词, 我们需要掌握常见的前缀和后缀及派生规律。(1) 常见
