4.According to advertisements, the higher a suntan lotion’s sun protection factor, or SPF, the more protection from sunburn. In order for a suntan lotion to work, however, one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed. Therefore, it really does not matter what SPF a suntan lotion has. Which one of the following best identifies the error in reasoning made in the passage? (A) It is unreasonable to assume that the only purpose of a suntan lotion is to provide protection from sunburn. (B) Because some people get sunburned more easily than others, the fact that there are different SPFs cannot be ignored. (C) It cannot be concluded that the SPF is not important just because there are requirements for the application of the suntan lotion. (D) It is unreasonable to assume that all suntan lotions require the same application. (E) There is no reason to assume that manufacturers are unaware that people sometimes forget to apply suntan lotion before going in the sun. 答案是C。我觉得理解上有点问题。 我看答案后反推这里要表达的意思：似乎在说原文描述的内容其实本无因果关系，但是却得到了因果结论。 但是我觉得原文要表达的意思是，suntan lotion 中的SPF越多，防晒能力越好，因此只要好好用suntan lotion，不论suntan lotion 中含有什么种类的SPF都无所谓（原文最后一句）。暗示SPF有多种，可能有的防晒能力强，有的防晒能力差。 因此，我觉得作者意图在于强调SPF的种类（能力好和差）不如数量重要。反驳这个观点，我觉得和C选项中的requirements for the application of the suntan lotion.根本就无关。 请NN指教
you need to identify where the argument goes wrong. The reasoning of the passage: Evidence: there are requirements for the application of the suntan lotion:
Conclusion: it really does not matter what SPF a suntan lotion has. The same as to say that SPF is not important.
C is correct answer. It identifies a faulty reasoning the author made (…not important because of some requirements)
FACTs According to advertisements, the higher a suntan lotion’s sun protection factor, or SPF, the more protection from sunburn. spf 越多----->protection 越多 PREMISE In order for a suntan lotion to work, however, one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed. CONCLUSION Therefore, it really does not matter what SPF a suntan lotion has. Reasoning Line 不通 要使生效就要出门前抹抹(reapply)Lotion---x--->一个Lotion有多少SPF无所 答案就是这么说的 It cannot be concluded that the SPF is not important just because there are requirements for the application of the suntan lotion. 答案是C。我觉得理解上有点问题。

同意.....

C的表述是有问题的。题目最后明明说：“it really does not matter what SPF a suntan lotion has.”但是C的选项说的却是：“It cannot be concluded that the SPF is not important ”。使用哪种SPF不重要和是否使用SPF不重要根本就是两回事。
