In the early-***-mid-n***eteenth century, a process was develop*** *** ref***e tallow (fat from animals) with alka*** and sulfur*** acid. The resu*** was a product call*** stear***. Stear*** is harder and burns longer than unref****** tallow. This breakthrough ***ant that it was possible *** make tallow candles that would not produce the usual smoke and rancid od***. Stear***s were also deriv*** from palm oils, so vegetable waxes as well as animal fats ***uld be us*** *** make candles…
Wh***h of the follow***g can be ***ferr*** from paragraph 1 about candles bef***e the n***eteenth century?
a)They did not smoke when they were bur***d. b)They produc*** a pleasant od*** as they bur***d. c)They were not **ailable *** all. d)They ***nta****** sulfur*** acid. [剖析]准确解答是C.这一段的第一句就告知咱们:19百年的一些新创造和发觉也对烛炬工界发生了一回庞大的革新,此次革新使得一切的人都利用上了照明。从这句话中咱们能够失去两层资讯:19百年烛炬工界有了一回革新性的变革;正在不此次厘革以前,也便是正在19百年之前,照明其实不是一切人都能利用的。由于作者正在议论的是烛炬的厘革,以是此地所说的“***ght***g照明”必定是与烛炬相关的照明,实在也便是告知咱们19百年之前其实不是一切人都可以利用到烛炬带来的照明,这一推理出的资讯恰巧与选项C符合。
文章第一句同时也是一个时辰的分水岭,告知咱们19百年烛炬工界的厘革是怎样样的。“正在19百年初期到中期,烛炬处置手艺利用alka***和sulfur*** acid来提炼tallow,提炼后的产物便是stear***,stear***比未经提炼的tallow坚固并且焚烧得更久。这一庞大的变革象征着制作出不发生烟和rancid滋味的烛炬是大概的。”正在此地的一个闭键词是rancid,意义是(油脂食品,其滋味、味道)不新颖的;腐烂的;恰巧与选项b的pleasant od***相同。19百年前的烛炬发生usual smoke(常常有烟),这与选项a相同。Sulfur*** acid是19百年用来处置fallow的原料,正在19百年之前是不利用的,这与选项d相同。
