Day 17
1. 晒皮肤
劝人们要晒皮肤的话去晒灯不要直接晒太阳,因为晒灯里大部分是UVA,太阳里面还有很多UVB,UVC,那些对人体有害的,问怎么削弱。
F:晒灯里大部分是UVA, 太阳除了UVA还有UVB,UVC→有害
C:劝人晒皮肤去晒灯不晒太阳
Q:weaken
思路:题干没有指出晒的时长。
选晒时间短太阳不会有副作用反而其他好处的选项或者UVA害处?的选项
2. 乡下的小鱼场
大致是说乡下小店么离渔场又近,进价又便宜,生意上的开销和城里大店一样,但是生意依然不好,问为啥啊。
F:乡下小店距离,进价优势,开销和城里一样
C:生意不好
Q:assumption
思路:生意不好和客人有关系,选客人少/本地人不吃鱼,卖到城里会提高费用之类的选项
3. Lead 会不会生病
说原来铅中毒的人很多,因为原来的水管都是铅(lead)做的。水里面含了铅,人喝了就中毒了。但是后来有人发现有些地方的人的血液里的铅含量很少。问哪一个可以解释这个问题。
F:lead水管→原来铅中毒人很多
P:水里面含了铅,人喝了就中毒了
C:有人发现有些地方的人的血液里的铅含量很少
Q:解释、weaken
思路:有些地方的人天赋异基因优势或者吃了什么吸附的食物可以代谢 OR 这些地方工业污染少而人中毒其实不是pipe而是水源被污染
认为是下面这个题:
Reviewer: The author of a recent book argues that lead contributed to many public health problems in the late nineteenth and early twentieth centuries. He claims that the main sources of this pollutant were urban water-delivery systems, which used lead pipes that leached lead into the water supply. But my own research on municipalities that used lead pipes during the period in question has shown that the inhabitants of several of them did not exhibit symptoms of lead poisoning, so the pipes are most likely not the primary culprit.
Which of the following would, if true, most *weaken* the reviewer’s reasoning?
(A) In certain areas, exposure to hard water—water with a high mineral content—promotes the formation of a protective coating on the interior of lead pipes.
选A
(B) In the late nineteenth and early twentieth centuries, many household fixtures and consumer products contained lead.
不能说明area范围
(C) Lead was introduced into gasoline in the 1920s, during which time lead-poisoning symptoms increased in many locales.
年代不匹配?
(D) Several cities that used lead pipes exhibited unusual rates of convulsive disorders and other conditions associated with lead exposure.
介绍conditions无关选项
(E) The author in question notes that other factors, including inadequate sewer systems and urban crowding; caused widespread outbreaks of infectious diseases.
