了解英语构词法(Word Formation)和前缀(prefix)、后缀(suffix)英语单词构成有其规律，很好的掌握了构词规律，才可以很好、很快的、准确的记忆单词。常见的构词法有合成(Compounding)、派生(Derivation)和转化(Conversion)。前缀和后缀属于派生法。英语单词的核心部分，在于词根(root)，词的意义主要是由组成单词的词根体现出来的。词根可以单独构成词，也可以彼此组合成词，通过前缀(prefix)后缀(suffix)来改变单词的词性和意义。也就是说，单词一般由三部分组成：词根、前缀和后缀。词根决定单词意思，前缀改变单词词义，后缀决定单词词性。
单词中位于词根前面的部分就是前缀。前缀，可以改变单词的意思。常见的前缀有如下几类：
前缀
意义
举例
di/ dis
否定
disagree 不同意
il/im/in/ir
否定
illegal非法的；impossible不可能的；impolite不礼貌的；irrational不合理的
mid
中间
midnight半夜；midsummer仲夏
non
否定
nonsmoker不抽烟的人
over
过度
overwork工作过度
un
否定
unusual 不寻常的
mis
错，坏
misunderstand误会；misspell拼错
re
回，再
return返回; review复习

后缀：英语单词中的后缀没有任何实在意义，只表示词性。常用的后缀有三种：动词后缀、名词后缀和形容词后缀。例如：
后缀
意义
举例
able 形容词化
可…的；能…的
comfortable舒适的；
reusable可重复利用的
ance, ence 名词化
状态，行为，性质
importance重要性；confidence自信
ful 形容词化
具有……的性质
helpful有帮助的；useful有用的
ion, tion, sion名词化
情况，状态，性质，行为
expression表达； suggestion建议；celebration庆祝
less 形容词化
否定
useless无用的；fearless无畏的
ness 名词化
状态；性质
kindness善良；sadness悲伤；
darkness黑夜; happiness快乐
en 动词化
使……
shorten (v.) 缩短

1. Do you often throw away things you don’t need anymore?
1) throw away扔掉，丢弃浪费 (机会、优势或好处)
e.g. I never throw anything away. 我从来不扔任何东西。
2) 错过(机会等)，放过；未能很好利用(机会等)

3. The top of the house is an old boat turned upside down.
turned upside down 意为“被翻转过来的；被颠倒过来的”，作后置定语修饰boat。英语中短语和从句用作定语时, 一般置于名词之后, 作后置定语。
e.g. the sigh on the wall 墙上的标志牌
(介词短语后置作定语)
the children boating on the lake湖上泛舟的孩子们
(现在分词短语后置作定语)
the stories invented by eight-and nine-year-olds 八九岁小孩子编写的故事
(过去分词短语后置作定语)

4. Not only can the art bring happiness to others, but it also shows that even cold,
hard iron can be brought back to life with a little creativity.
