<p> 基础知识 构词法的讲解与训练</p><p> 构词法</p><p> 知识要点</p><p> 英语构词方法主要有三种：即合成法、派生法<span word="derivation">derivation</span> )和转化法。</p><p> 1合成法：将两个或两个以上的单词合成在一起而构成的新词，叫做合成词。：<span word="snow">snow</span>-<span word="white">white</span> 雪白的<span word="day">day</span>-<span word="long">long</span> 整天的</p><p> 2. 派生法：所谓派生，即在词根上加前缀或后缀构成另一个与原意略有变化或截然相反的词。例：<span word="discover">discover</span> 发现<span word="disagree">disagree</span> 不同意的<span word="nation">nation</span>→<span word="national">national</span> 民族的，国家的；<span word="nature">nature</span>→<span word="natural">natural</span> 自然的<span word="treatment">treatment</span> 治疗<span word="development">development</span> 开发展</p><p> 转化法：英语单词的词性非常活跃，名词用作动词，动词转化为名词，形容词用作动词等现象非常普遍，这种把一种词性用作另一种词性的方式就叫做词性的转化。：</p><p> 有大量动词可以转化为名词，有时意思没变化。</p><p> <span word="Let">Let</span> <span word="me">me</span> <span word="have">have</span> <span word="a">a</span> <span word="try">try</span>. 让我试一试。</p><p> 名词转化为动词</p><p> </p><p> <span word="Have">Have</span> <span word="you">you</span> <span word="booked">booked</span> <span word="your">your</span> <span word="ticket">ticket</span>?你的票订好了吗？</p><p> 一些表示某类人的名词也可做动词</p><p> </p><p> <span word="If">If</span> <span word="so">so</span>,<span word="we">we</span> <span word="shall">shall</span> <span word="be">be</span> <span word="badly">badly</span> <span word="fooled">fooled</span>. 如果这样我们就会上大当。</p><p> 形容词转化为动词</p><p> </p><p> <span word="The">The</span> <span word="train">train</span> <span word="slowed">slowed</span> <span word="down">down</span> <span word="to">to</span> <span word="half">half</span> <span word="its">its</span> <span word="speed">speed</span>.火车速度减慢了一半。</p>
