  ①名词+名词,如

  daybreak, sunrise, cattleshed, house-keeper, shoe-maker, headache, night-club, pocket-knife, arm-chair, wine-glass, ink-stand, man-servant, maid-servant, steamboat, goldsmith, newspaper, lawsuit等。

  ②形容词+名词,如

  blackboard, commonweath, highway, stronghold, sweetheart, easy-chair, grandson, blueprint, deadline, high-brow, lazy-bones等。

  ③动词+名词,如

  drawbridge, grindstone, playground, pickpocket, breakfast, cut-throat, makeshift, sing-song, turn-coat, washbasin 等。

  ④副词虚词+名词,如

  afterthought, offshoot, outbreak, byway, bylaw, outpost, overcoat, underclothes, outgrowth, downpour, upkeep, bystander等。

  ⑤副词虚词+动词,如

  income, outlet, outlook, onset, outfit, upstart, inlet, offspring, outburst, offset等。

  ⑥动词+副词,如

  die-hard, breakdown, drawback, set-up, break-up, farewell, standstill, feedback等。

  ⑦名词+动名词,如

  book-keeping, town-planning, letter-writing, word-building, tiger-hunting, paper-manufacturing, bill-collecting, car-repairing, television-advertising, window-shopping, day-dreaming, photocopying, handwriting等。

  ⑧其他,如

  man-of-war, forget-me-not, son-in-law, mother-in-law, commander-in-chief, editor-in-chief, merry-go-round, hide-and-seek, stay-at-home, jack-in-the-box等。

  在这8种构词法中,第7类“名词+动名词”最富生命力。此外,动名词还可以下列三形式构成合成名词:

  ㈠动名词+名词,如

  drinking water, listening material, fishingrod, waiting-room, looking-glass, stepping-stone, running mate 等。

  ㈡动名词+副词虚词,如

  能用作宾语补足语的过去分词一般都是及物动词,表示被动意义或已完成意义,有时候两者兼而有之。作宾语补足语的过去分词与宾语有逻辑上的动宾关系,即宾语是过去分词动作的对象。

  She found the door broken in when she came back.她回来时发现有人破门而人。

  My grandfather had his old house rebuilt.我爷爷找人重修了一下他的旧房子。

  少数不及物动词的过去分词用作宾补时,强调动作完成后的状态.

  They found all the guests gone when they woke up.当他们醒来时,发现所有的客人都走了。

  动词-ed形式作宾语补足语的基本用法

  动词的-ed形式可以在“主语+谓语+宾语+宾语补足语”句型中充当宾语补足语。在这一结构中,动词-ed形式和它前面的宾语构成逻辑上的被动关系。如果这种句子改为被动语态,原来的宾语补足语变成了主语补足语。

  1. I must get my bike repaired.我必须请人修理自行车。(宾语补足语)

  2. The girl was found beaten black and blue.人们发现那女孩被打得青一块紫一块。(主语补足语)

  I have my hair cut once a month.我每个月理一次发。

  He was trying to make himself understood.他正努力使别人听懂自己。

  “have+宾语+done”结构有三个含义:

  ①(请人)把某事做完。She had her house repaired.她请人把屋子修好了。

  Where did you have your hair cut?你在哪儿理的发?

  ②遭遇某种意外情况。He had his hat blown away on his way home.在回家的路上他的帽子被吹掉了。

  She had her wallet stolen yesterday.昨天她的钱包被偷了。

  ③完成某事(自己也可能参与)。I have had all my spelling mistakes corrected.我把所有的拼写错误都改正了。

  He has had one thousand yuan saved this year.他今年已存了1000元。

  (3)动词-ed形式可作表示希望、要求、命令等动词的宾语补足语,这类动词包括like,want, wish, expect, order等”这一类动词的后面作宾语补足语。

  He won’t like such questions discussed at the meeting.他不喜欢在会议上讨论这样的问题。

  The students wish the TV serial plays continued.学生们希望电视连续剧继续播下去。

  (4)过去分词用在“with+宾语+宾补”这一结构中,过去分词与宾语之间是动宾关系。
