前缀(prefix): A prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the words to which it is affixed. Prefixes are either inflectional, creating a new form of the word with the same basic meaning and same lexical category (but playing a different role in the sentence), or derivational, creating a new word with a new semantic meaning and sometimes also a different lexical category. Prefixes, like all other affixes, are usually bound morphemes. ----------------------------------------------------------------------------------------------- 69. over- 过度;在上,在外 overdue a.过期未付的;逾期的 overemphasize v.过分强调 overflow v.滥出;充满 overlap v.(部分地)重叠 overlook v.忽视:俯视 overpower v.压倒 overpowering a.压倒性的,不可抗拒的 overriding a.最主要的,优先的 overshadow v.遮蔽,使失色 overwhelm v.泛滥;压倒 oversee v.监视 70. paleo- 古,旧 paleozoology n.古动物学 paleobotany n.古植物学 paleoclimate n.古气候学 paleoanthropology n.古人类学 71. pan- 全部 panacea n.万灵药 pandemic a.(疾病)大范围流行的 pandemonium n.喧器,大混乱 panegyric n.颂词,颂扬 panorama n.概观,全景 panoramic a.全景的, 全貌的,概论的 pantechnicon n.家具仓库,家具搬运车 pantheon n.万神殿 72. para- 类似,穿边,靠近 parallel a.平行的;类似的, n.平行线;v.与...相似 parallelism n.平行,类似 unparalleled a.无比的,空前的 paramount a.最重要的,最高权力的 parasite n.食客;寄生物 parasitic a.寄生的 73. pen- 几乎,近于 peninsula n.半岛(insular a.岛屿的;心胸狭窄的) penultimate a.倒数第一的(ultimate a.最后的) 74. penta- 五 pentagon n.五角形 pentoxide n.五氧化物 pentagram n.五角星形 75. per- 贯穿,完全,始终/远离 permeable ad.可渗透的 permeate v扩散,渗透 pervious a.可渗透的 impervious a.不能渗透的;不为所动的 perambulate v.巡视;漫步 persevere v.坚持不懈 (severe a.严格的;凶猛的) perpetual ad.连续不断的:永久的 perpetuate v.使永存,使永记不忘 perfidious ad不忠的,背信弃义的 perfidy n.不忠,背叛 76. peri- 周围,环绕 perimeter n.周长 periodic a.周期的,定期的 periodical n.期刊 peripatetic a.巡游的 peripheral a.不重要的,外围的 periphery n.不重要的部分;外围 periphrastic a.连回的,冗赘的 periscope n.潜望镜 77. poly- 多 polymath n.知识广博者 polyandry n.一妻多夫制 polygamy n.一夫多妻制,一妻多夫制 polyglot a. n.通晓多种语言的(人) 78. post- 后 postdate v.填迟...的日期 posterior a.(在时间、次序上)较后的 posthumous a.死后的,身后的 posthumously adv.死后地 postoperative a.手术后的 postpone v.使延期,推迟 postscript n.附言,后记 postwar a.战后的 79. pre- 前,预先 precede v.在…之前,早于 precursor n.先驱,先兆 predictable a.可预知的 preface n.序言 prehistoric a.史前的 |
