But many f them are frmed using ther simpler wrds. This is called wrd frmatin.Wrds frmed by cmbining ther wrds are called cmpunds, fr example, 1______________ (a friend that yu cntact by writing, traditinally using a pen) and 2_______________ (knwn by many peple).Prefixes and suffixes ften have fixed meanings. If yu add un- r in- t a wrd, the new wrd usually means the ppsite.
Review: Wrd frmatinFr example, if smething isn’t crrect it’s 3__________, and if smene isn’t happy they’re 4__________. Wrds with the suffixes -ment and -ness are ften nuns. Fr example, if smebdy has imprved a lt, they have made great 5____________.Sme nuns and adjectives can be used as verbs, r the ther way rund. When we calm smebdy dwn, they becme 6__________. And we can give smene a present by 7__________ it.
Review: Wrd frmatinAnd smetimes a wrd is made up f the first letters f several wrds: “Wrld Trade Organizatin” can be referred t as 8__________, and 9__________ is shrt fr “as sn as pssible”. It is impssible t knw the meaning f every wrd, but knwing abut wrd frmatin can help us guess their meanings.

构词法英语构词法主要有四种：派生法、合成法、转化法和缩略法。1 派生法在一个词根的前面或后面加上某个词缀生成一个新词，这种构词法称为派生法。加在前面的词缀叫前缀，加在后面的词缀叫后缀。（1）前缀前缀一般只改变词的意义，不改变词性。
①表示否定意义的前缀
（2）后缀：后缀通常改变词性，构成意思相近的其他词性的词，少数后缀会改变词义。①形容词后缀
