初三英語合成名詞知識點 1
在英語合成詞中，合成名詞(compound nouns)數量很多，而且可以按照既定規律自行構造新詞。
合成名詞構造法主要有下列八種：
①名詞+名詞，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形容詞+名詞，如
blackboard, commonweath, highway, stronghold, sweetheart, easy-chair, grandson, blueprint, deadline, high-brow, lazy-bones等。
③動詞+名詞，如
drawbridge, grindstone, playground, pickpocket, breakfast, cut-throat, makeshift, sing-song, turn-coat, washbasin 等。
④副詞虛詞+名詞，如
afterthought, offshoot, outbreak, byway, bylaw, outpost, overcoat, underclothes, outgrowth, downpour, upkeep, bystander等。
⑤副詞虛詞+動詞，如
income, outlet, outlook, onset, outfit, upstart, inlet, offspring, outburst, offset等。
⑥動詞+副詞，如
die-hard, breakdown, drawback, set-up, break-up, farewell, standstill, feedback等。
⑦名詞+動名詞，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。
在這8種構詞法中，第7類“名詞+動名詞”最富生命力。此外，動名詞還可以下列三形式構成合成名詞：
㈠動名詞+名詞，如
drinking water, listening material, fishingrod, waiting-room, looking-glass, stepping-stone, running mate 等。
㈡動名詞+副詞虛詞，如
swearing-in, going-over
㈢副詞+動名詞，如
uprising, well-being 等。

能用作賓語補足語的過去分詞一般都是及物動詞,表示被動意義或已完成意義,有時候兩者兼而有之。作賓語補足語的過去分詞與賓語有邏輯上的動賓關系,即賓語是過去分詞動作的對象。
She found the door broken in when she came back.她回來時發現有人破門而人。
My grandfather had his old house rebuilt.我爺爺找人重修了一下他的舊房子。
少數不及物動詞的過去分詞用作賓補時,強調動作完成后的狀態.
They found all the guests gone when they woke up.當他們醒來時,發現所有的客人都走了。
動詞-ed形式作賓語補足語的基本用法
動詞的-ed形式可以在“主語+謂語+賓語+賓語補足語”句型中充當賓語補足語。在這一結構中,動詞-ed形式和它前面的賓語構成邏輯上的被動關系。如果這種句子改為被動語態,原來的賓語補足語變成了主語補足語。
1. I must get my bike repaired.我必須請人修理自行車。(賓語補足語)
2. The girl was found beaten black and blue.人們發現那女孩被打得青一塊紫一塊。(主語補足語)
(1)動詞-ed形式可作表示感覺和心理狀態的動詞的賓語補足語,這類動詞包括see, hear, watch, notice, feel, find, think, suppose, consider等。
We thought the game lost.我們認為球賽輸了。
I have never heard him spoken ill of others.我從未聽過有人說他的'壞話。

I have my hair cut once a month.我每個月理一次發。
He was trying to make himself understood.他正努力使別人聽懂自己。
“have+賓語+done”結構有三個含義：
①(請人)把某事做完。She had her house repaired.她請人把屋子修好了。
Where did you have your hair cut?你在哪兒理的發?
②遭遇某種意外情況。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.昨天她的錢包被偷了。
③完成某事(自己也可能參與)。I have had all my spelling mistakes corrected.我把所有的拼寫錯誤都改正了。
He has had one thousand yuan saved this year.他今年已存了1000元。
(3)動詞-ed形式可作表示希望、要求、命令等動詞的賓語補足語，這類動詞包括like，want, wish, expect, order等”這一類動詞的后面作賓語補足語。
He won’t like such questions discussed at the meeting.他不喜歡在會議上討論這樣的問題。
The students wish the TV serial plays continued.學生們希望電視連續劇繼續播下去。
(4)過去分詞用在“with+賓語+賓補”這一結構中,過去分詞與賓語之間是動賓關系。
The thief was brought in with his hands tied behind his back.小偷被帶進來了,雙手被反綁在后面。
