(to send or transport sth. /sb. in a ship) ②形容词转化为动词：green (adj.)?→?green (v.) (to make ... environmentally friendly) ③介词转化为名词：the?ups?and?downs?of life ④连词转化为名词：no?ifs, ands, or?buts★派生是指通过给一个单词加前缀或后缀构 成另一个词。（前缀一般改变词义而不改变 词性，后缀一般改变词性而不改变词义）如：注意： 1.?在合成词中有的词连写，有的词不连写，有 的词之间用连字符连接。如： keyboard, network, newspaper bus stop, post office high-speed, CD-ROM, warm-up 2.?合成形容词被视为一个单词，常放在所修饰 词的前面。如： Do you know the?middle-aged?man sitting on the chair? My neighbour is a?kind-hearted?lady.Compound words are made from two words: two separate words (roller coaster), one word (craftsmen) or words joined by a hyphen (old-fashioned).
