[我的发现] 上述句子中加黑部分都是复合词，你能说出它们的构成方式吗？ 语法规则点拨 在英语中把两个(或更多)独立的单词合在一起构成一个新词，其意义为原来单词意义的叠加，用这种方式构成的单词叫复合词(compound words)。 1．复合名词的主要构成方式 构成方式 例词 n.＋n. suitcase手提箱　mankind人类　eggplant茄子 adj.＋n. greenhouse温室　highway公路　shorthand速记　blackboard黑板 v.＋n. breakwater防波堤　pickpocket扒手playground操场 adv.＋v. outbreak爆发　output产量downfall垮台　income收入 n.＋prep.＋n. daughter-in-law儿媳 其他方式 hide-and-seek捉迷藏daybreak拂晓　grown-up大人 2.复合形容词的主要构成方式 构成方式 例词 adj.＋n.＋-ed warm-hearted热心肠的good-tempered脾气好的 adj.＋v.-ing good-looking漂亮的easy-going随和的 adv.＋v.-ing hard-working工作努力的far-reaching影响深远的 n.＋v.-ing peace-loving爱好和平的time-saving节省时间的 n.＋v.-ed handmade手工制成的snow-covered被雪覆盖的 adv.＋v.-ed newly-built新建的well-informed见多识广的 adj./adv.＋n. full-time全职的high-class高级的　indoor室内的 n.＋adj. homesick想家的snow-white雪白的 num.＋n. one-way单程的three-piece三件一套的 num.＋n.＋-ed four-legged四条腿的two-sided两方面的 3.复合动词的主要构成方式 构成方式 例词 n.＋v. sunbathe沐日光浴hand-pick精心挑选 adv.＋v. overhear无意中听到upset打翻；使烦恼　undergo经历 adj.＋v. safeguard保卫　dry-clean干洗 4.复合副词的主要构成方式 构成方式 例词 adj.＋n. first-hand直接地，第一手地 prep.＋n. overnight在晚上；一夜之间 adv.＋prep. thereafter此后 5.复合介词的主要构成方式 构成方式 例词 adv.＋n. outside在……外面 prep.＋adv. throughout 遍及，到处 6.构成复合词时要注意以下几点 (1)由“数词＋名词(＋形容词)”构成形容词时，名词不用复数，如：a four-day trip“一次为期四天的旅行”；the 100-metre dash“百米赛跑”；an 800-metre-long bridge“一座八百米长的桥”。 (2)由“形容词＋名词＋-ed”构成的形容词，该名词必须是中心词的一部分，否则不加-ed, 如：a warm-hearted girl“一个热心肠的女孩”；a near-sighted boy“一个近视的男孩”；two middle-aged men“两个中年男子”。 (3)由“形容词＋分词”构成的合成形容词，要注意中心词与分词的主动或被动关系，如：an easy-going man“一个随和的人”；fresh-baked bread“刚烤的面包”；ready-made goods“现成的货物”。 (4)由“副词＋分词”构成的合成形容词，副词是修饰分词的状语，用现在分词还是过去分词由它与中心词的主动或被动关系而定，如：bravely-fighting soldiers“勇敢战斗的战士”；a well-known singer“一个有名的歌唱家”；the newly-married couple“那对新婚夫妇”。 |名师点津| (1)现在分词与所修饰的名词在逻辑上是主动关系，如：an ordinary-looking man＝a man who looks ordinary。 (2)过去分词与所修饰的名词在逻辑上是被动关系，形容词相当于补语，如：clean-washed clothes＝clothes which are washed clean。 即时应用体验 Ⅰ.写出下列复合词的意思 1．English-speaking　　　　　 讲英语的 2．get-together 聚会 3．hard-working 辛勤工作的 4．well-known 著名的 5．after-class 课外的 6．greenhouse 温室 7．motorway 高速公路 8．overcome 克服 Ⅱ.用复合词完成句子 1．(2025·全国Ⅱ卷写作)Every time I gave a self-introduction, I had to explain how to pronounce my name at least five times, yet they still could not say it the way I did. 每次做自我介绍时，我都得至少解释五遍自己的名字怎么发音，可他们还是没法像我那样念对。 2．I'm only part-time at the moment. 现在我只是兼职。 3．She burst into tears at the heartbreaking news. 听到这令人心碎的消息，她号啕大哭起来。 4．He returned home empty-handed. 他两手空空地回了家。 5．Her easy-going nature made her popular. 她个性随和，大家都很喜欢她。 学科网（北京）股份有限公司 $
