1．否定前缀否定前缀dis­、im­、in­、il­、ir­、nn­、un­等加在词前，使原先表肯定意义的词变为否定的含义。【例题】(湖北荆门)I'm busy these days.Hanging ut with friends is almst ______ (pssible) fr me nw.【答案】impssible【解析】由第一句句意“我这些天很忙”可知，现在和朋友出去逛街对“我”来说是不可能的。
2．一些名词后缀的用法名词后缀­n、­an、­ian、­ese表示 “……地方的人；某国人”。­an、­ian还可表示 “精通……的人”。【例题】The little girl hpes t be a ______ (music) in the future.【答案】musician【解析】句意：那个小女孩希望将来成为一名音乐家。“音乐家”的英文单词是在music后加­ian。
3．一些以后缀­er、­r 结尾的名词在动词后加后缀­er、­r可表示 “从事某种动作的人”，如teacher、visitr、peratr、inventr、player、actr、cnductr、editr等。【例题】(江苏扬州改编)As a great ______(invent)，Thmas Edisn made a difference t ur life.【答案】inventr【解析】a修饰可数名词单数形式，invent是动词，此处表示“发明家”所以应填inventr。
4．以­ing 和以­ed结尾的形容词的用法区别以­ing结尾的形容词常与表示事物的名词或代词连用，说明某事物怎样；以­ed结尾的形容词常与表示人的名词或代词连用，说明人的感觉如何。【例题】(山东临沂)We have already learned many ______(interest) ways t relax.【答案】interesting【解析】句意：我们已经学到了许多有趣的放松方式。 ways指物，用interesting修饰。
5．部分名词加后缀­ful和­less表示相反的意思有些词加后缀­ful和­less后表示相反的意思，如careful(仔细的)—careless(粗心的)。【例题】Yu shuld be ______ (care) when ding yur hmewrk.【答案】careful【解析】句意：你做作业应该仔细点。由题空前的be和句意可知此处应填一个形容词。careful仔细的；careless粗心的。
6．以后缀­y结尾的形容词某些名词加后缀­y构成形容词，表示“充满……的”，如cludy(多云的)、windy(有风的)、dirty(肮脏的)、healthy(健康的)、lucky(幸运的)等。【例题】 D yu think it will be ______ (sun) r ______(clud) tmrrw?【答案】sunny；cludy
