Grammar--构词法--合成法
1.合成词构词法英语中构成新词最基本的方法有三种：合成法，缩略法和词缀法。合成词构词法就是将两个独立的单词和在一起构成一个新的单词。常见的方法有：(1). 合成名词
hmewrk(家庭作业)
space + ship—spaceship(宇宙飞船)
after + nn—afternn(下午)
ill + treat—ill-treat(虐待)
sight + see—sight-see(观光)
hard + wrking—hard-wrking(勤奋的)
well + knwn—well-knwn(著名的)
wrld + famus—wrld-famus(世界闻名的)
dwn + stair—dwnstairs(在楼下)
up + stairs—upstairs(在楼上)
sme +bdy—smebdy(某人)
any +ne—anyne(任何人)
with +in—within(在…之内)
in +t—int(到…)
Grammar--构词法--派生法
在一个单词前或后加上一个词缀，就可以构成一个新词。 根据词缀的位置，分为前缀和后缀两种。掌握一些常见的词缀，对单词的记忆和理解有很大的帮助。比如：我们学会care, 就能掌握careful, careless, carefully, carelessly。xi'yan'zh下面我们来学习几个常见的前、后缀：
