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。
太阳还有其他晒灯没有的优点，同时UVA也不完全无害
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。
顾客过来的交通成本太高
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?D
(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.
(E) The author in question notes that other factors, including inadequate sewer systems and urban crowding; caused widespread outbreaks of infectious diseases.

P: 太阳光有UVB，UVC对人体有害物质
C：晒皮肤去晒灯不要晒太阳
GAP：1、正常晒太阳UVB，UVC有害物质很低，很难对人体造成伤害；2、找晒太阳的好处  3、找晒灯的危害；
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: 乡下小店由于离渔场近，成本低
C：生意不好
GAP：1、乡下消费者少 2、虽然成本低，乡下人收入也低
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。

水管里的lead会造成水污染导致健康问题
调查几个大城市都没有这个问题，所以水管不是culprit
gap: 可能水管里含铅量少

UVA对人体也有害
2.        乡下的小鱼场

小店质量没保证；离顾客距离远，交通不便利

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。
UVA也有害处，要达到相同程度的皮肤结果，晒灯需要的时间要长于晒太阳，总的危害就不比太阳少
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。
乡下小店环境不好or打广告打的少，所以吸引不来那么多的顾客
3.        Lead 会不会生病

        晒皮肤
•        P：太阳里面还有很多UVB UVC 对人体有害
•        C：要晒皮肤的话去晒灯不要直接晒太阳
•        Weaken：证明晒灯也有不好的，比如UVA会转化成有害的物质/ 证明太阳光没有那么大危害，比如有别的物质会中和UVB UVC的作用

        乡下的小鱼场
•        Gap：生意不好意味着收入低，小店成本低不代表收入高，可能是店的位置离消费者太远/ 不会做marketing / 价格没有优势等能影响收入的原因

        Lead 会不会生病
•        P：有些地方的人们没有铅中毒的症状
•        C：管道不是造成铅中毒的原因
•        Weaken：选A，水里的矿物质形成保护膜隔离了管道里的铅
