Paragraph 6: Perhaps so much time has passed that there will never be satisfactory answers to the cave images, but their mystique only adds to their importance. Certainly a great art exists, and by its existence reveals that ancient human beings were not without intelligence, skill, and sensitivity.
According to paragraph 6, why might the puzzling questions about the paintings never be answered?
A. Keeping the paintings a mystery will increase their importance.
B. The artists hid their tools with great intelligence and skill.
C. Too many years have gone by since the images were painted.
D. Answering the questions is not very important to scholars.
这道题所对应的段落非常短，定位很容易，想要把这段看懂也不是什么难事，重点是想要把这道题选对就蛮有迷惑性的了。首先，我们通过puzzling questions和never be answered进行定位，在行顺利找到出处。然后我们发现，这句话的后半句出现了闪亮亮的but，很多托儿们开始顺势往后读，发现出现了mystique adds to their importance，所以答案选A。其实在做这道题时，托儿们犯了两个致命的错误。，虽然划了定位词，但是忽略了考点词，why，这道题问的是原因，所以我们应该在原文中找因果关系词；第二，草率地认为转折之后是答案。出现转折词，我们知道转折词前后意思相反，托福阅读除了*后一个题型都在考察细节，所以其实答案取决于定位的信息，如果定位的信息在转折词之前，答案就是前面，反之亦然。
再看一遍原文，我们不难发现一个因果关系词：so...that..表示“如此…以至于”，so...that中间的表示原因，所以答案是so much time has passed，和时间有关。正确答案是C。
下面朗阁海外考试研究中心的帮助大家总结了托福阅读TPO中高频出现的转折关系词：but, however, in spite of, despite, although, though, instead of, nevertheless, nonetheless, yet, while, whereas.
Paragraph1: The earliest discovered traces of art are beads and carvings, and then paintings, from sites dating back to the Upper Paleolithic period. We might expect that early artistic efforts would be crude, but the cave paintings of Spain and southern France show a marked degree of skill. So do the naturalistic paintings on slabs of stone excavated in southern Africa. Some of those slabs appear to have been painted as much as 28,000 years ago, which suggests that painting in Africa is as old as painting in Europe. But painting may be even older than that. The early Australians may have painted on the walls of rock shelters and cliff faces at least 30,000 years ago, and maybe as much as 60,000 years ago.
Paragraph 1 supports which of the following statements about painting in Europe?
A. It is much older than painting in Australia.
B. It is as much as 28,000 years old.
C. It is not as old as painting in southern Africa.
D. It is much more than 30,000 years old.
The structure of the backbone shows, however, that Ambulocetus swam like modern whales by moving the rear portion of its body up and down, even though a fluke was missing.
A. Even though Ambulocetus swam by moving its body up and down, it did not have a backbone.
B. The backbone of Ambulocetus , which allowed it to swim, provides evidence of its missing bone.
C. Although Ambulocetus had no fluke, its backbone structure shows that it swam like modern whales.
D. By moving the rear parts of their bodies up and down, modern whales swim in a different way from the way Ambulocetus swam.
细心的托儿们发现，这句话中出现了两个转折关系词：however和even though，但是真正表达转折关系的其实只有even though，因为however前后出现逗号，表明它是插入语，however真正的位置应该是句首，表明这句话和上句话是转折关系。而句子简化题考查的是句子内部的逻辑关系，所以even though是真正的转折关系词。我们再来看一下四个选项，其中A和C出现了转折词：even though和although，所以我们优先看这两个选项。A选项说it did not have a backbone，很明显和句子意思不符。C选项，完全是文中句子的同义改写，所以是正确答案。
