Day 17
1.        晒灯有其他副作用
晒灯真的能达到晒皮肤的作用
不是所有人都能晒灯
太阳里UVB\UVC含量低对人类无害
2.        利润=收入-成本
成本一样，说明收入低，收入=单价*数量
        鱼的单价低
        乡下太远、做的不好吃等原因，导致没客流
3.        果：铅导致公共卫生问题
因：铅来自用了铅管的下水道系统，从而影响供水系统
argue：有一些用铅管的城市没有铅中毒的现象，所以铅管不是罪魁祸首。

削弱argue：
A：correct，因为有保护层（铅管上的铅没有进入下水系统）
B\C\E：都是它因，加强了argue
D：有点类似相关因果，不一定成立

格温呆呆

1. 晒太阳
p因为太阳光里有成分有害，
c所以不晒太阳去晒灯。
cq：人们不在意太阳光里的有害成分；
人们晒太阳是为了别的好处，该好处大于了晒太阳的坏处

2.去乡村不方便；客人少；去乡村路费贵

3.weaken水管不是主要原因，找水管是主要原因的选项，A选项

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。

P1:晒灯大部分是UVA，晒太阳还有UVB UVC
P2:UVB UVC对人体有害
C：应该选择晒灯而不是晒太阳
削弱：晒太阳更有效/UVBUVC都很微量不足以有严重的影响
①B 有更致命的缺点；②A 有 B 没有的有点

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。

P：乡下小店离渔场近，进价便宜，生意上的开销和大店一样
C：生意依然不好
GAP：影响生意的其他因素，除了进价和运输成本
猜测：乡下消费者少，人们都自给自足了
渔场收入＝总收益－总支出＝(鱼的单价－鱼的进价)×卖出的量－各种开销
单价/卖出的量两个方面找原因

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。
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.
(B) In the late nineteenth and early twentieth centuries, many household fixtures and consumer products contained lead.
(C) Lead was introduced into gasoline in the 1920s, during which time lead-poisoning symptoms increased in many locales.
(D) Several cities that used lead pipes exhibited unusual rates of convulsive disorders and other conditions associated with lead exposure. 错误，在问削弱reveiwer的论证，即没有导致铅中毒能不能说管道不是主要原因，没有问其他症状；如果是得这个病没有中毒迹象，不知道是不是可以
(E) The author in question notes that other factors, including inadequate sewer systems and urban crowding; caused widespread outbreaks of infectious diseases.
书作者：在一段时期lead导致了很多健康问题，主要是因为城市供水系统管道lead泄漏
reviewer：化验了用lead管道的城市居民，发现很多没有lead中毒症状；C：pipes不是主要原因
逻辑链：用lead pipe没有lead中毒迹象-pipes不是健康问题的主要原因
削弱就是打破逻辑链！
lead pipes - lead ； 没中毒迹象-没有健康问题
1.lead 不会溶于水中啊，一般饮用的水中含有的某个元素可以抵制 lead 对人体的危害啊，人们喝水会煮沸于是 lead 没危害了
2.其他导致的健康问题没有中毒迹象

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。
直接晒灯容易晒伤，因为UVA浓度过高
文章说两种方法 A 和 B，其中告诉你 A 有一个缺点，于是得出结论，要用 B。
这时候需要削弱的话，那么就去找选项，能够支持“应该用 A 更好”的选项，显然就是削弱了文章的观点。这类选项不外乎两种大的方向：
①B 有更致命的缺点；②A 有 B 没有的有点。

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。
乡下人买鱼很少，可以自己捕鱼？

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。
1、铅水管送水不等于水里有铅：
o        lead 不会溶于水中，
o        一般饮用的水中含有的某个元素可以抵制 lead 对人体的危害，
o        人们喝水会煮沸
2、没中毒，造成其他病-- XX 病并没有中毒迹象
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
(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.
(B) In the late nineteenth and early twentieth centuries, many household fixtures and consumer products contained lead. 无关
(C) Lead was introduced into gasoline in the 1920s, during which time lead-poisoning symptoms increased in many locales.无关
(D) Several cities that used lead pipes exhibited unusual rates of convulsive disorders and other conditions associated with lead exposure.加强了
(E) The author in question notes that other factors, including inadequate sewer systems and urban crowding; caused widespread outbreaks of infectious diseases.无关
