消化digest (基本义)
digest 语义网络图
Sme bks are t be tasted, thers t be swallwed, and sme few t be chewed and digested. 书有可浅尝者,有可吞食者,少数则须咀嚼消化。
这句话出自弗朗西斯·培根的《培根随笔》。原句为:书有可浅尝者,有可吞食者,少数则须咀嚼消化。换言之,有只需读其部分者,有只须大体涉猎者,少数则须全读,读时须全神贯注,孜孜不倦。指出了“粗读、泛读、精读”三种不同读书方法。弗朗西斯·培根(Francis Bacn)是英国文艺复兴时期散文家、哲学家。英国唯物主义哲学家,实验科学的创始人,是近代归纳法的创始人。
古代希腊哲学家认为世间除了常见的水、火、土、气等四种物质外,还存在第五种物质 (quinta essential),第五种物质是万物之精华,弥漫在所有其他物质中,是将四种物质有机组合的最重要因素。essential 词源义为“本质的”。
essential adj
必不可少的;最重要的 extremely imprtant and necessary (vital) ;本质的:Sun and water is / are essential t the grwth f crps.The wrds are essential fr everybdy t learn English.① it is essential + that ... (shuld) d sth:It is essential that yu get a visa befre yu travel t the USA.② it is essential fr sb t d sth:It is essential fr high-new technlgy enterprises t strengthen cmpetitive pwer.【词汇拓展】essentially adv 本质上;根本上 (basically)
看到上面两幅图,大家很容易想到风能和太阳能,这些自然能源即为“替代能源”(alternative energy)。此时,alternative 译为“可替代的”。
alternative adj [只用于名词前] 可供替代的;可供选择的 that yu can use, d, etc. instead f sth else:an alternative methd f learning The way was blcked, s we went by an alternative rad. 非传统的;另类的 different frm what is usual r traditinal:an alternative lifestyle alternative energy 替代能源(指太阳能、风能、水能等)alternative n [C] 选择;供选择的东西:Minibuses with seats fr 12 passengers ffer an alternative t expensive taxis and crwded public transprt.

三个词中,alternative 最正式,chice 较 ptin 稍非正式。 ptin, chice 或 alternative 均可表示可选择的事物。 alternative 较常用以指两个选择,后可接介词 t:Yu can be paid in cash weekly r by cheque mnthly; thse are the tw alternatives. 表示选择权或选择的自由时最常用 chice,有时也可用 ptin,但通常不用 alternative:D I have a chice f what clr t paint my rm? ptin 也指计算机程序里的选项、选择。
【辨析】alternative, chice, ptin
注:rt 由植物等的“根”,衍生到问题的“根源 ”。
Tree rts 树根
rt cause 根本原因
n [C] 根;根源;起源;词根:tree rtsMney is ften said t be the rt f all evil.After 20 years in America, he still feels his rts are in China.Mdern pp music has its rts in the flk sngs f black Americans.Wrds ften cme frm the same rt.vi & vt(使)生根;(使)扎根:With mther’s wrds deeply rted in my sul, I never dubted we wuld succeed.rt up 连根拔起
前缀 ex- 意为“ut”, 因此以此类词缀开头的单词大多都含有 _________之意。
ex- + tens (t stretch) + -in → extensin n ex- + tract (t draw) → extract v ex- + prt (t carry) → exprt v ex- + it (t g) → exit n ex- + pand (t spread, stretch) → expand v ex- + press (t press) → express v ex- + pect (t lk) → expect v ex- + pse (t place) → expse v
扩展;扩大;(使)膨胀
使暴露;揭露;使面临;使接触
形容词后缀-y 可加在名词后构成形容词,意为“充满……的 (full f)”或“有……特质的 (characterised by)”。
salt(盐)+ -y → salty adj water(水)+ -y → watery adj smke(烟)+ -y → smky adj mud(泥)+ -y → muddy adj bld(血)+ -y → bldy adj rse(玫瑰)+ -y → rsy adj silk(丝绸)+ -y → silky adj sleep(睡眠)+ -y → sleepy adj
