根據(jù)問題中的關(guān)鍵詞bronze statues of horses定位段末，這里有標(biāo)志詞for example，說明它是對前面所說的內(nèi)容進(jìn)行例證。前一句These are problems that must be overcome by the artist…就是概述：藝術(shù)家必須克服這些問題，因為這些問題破壞他們對藝術(shù)作品的構(gòu)思。這里所說的問題就是上文談?wù)摰奈锢硪?guī)律對美術(shù)的限制，如必須考慮制作材料的物理特性。而本題對應(yīng)的原文以例子說明這一點(diǎn)：由于銅的特性，馬抬起的前腿下必須有支撐物。綜上所述，例子說明它前面的概述，第一個選項符合此意，為正確答案。
又如，
One of the most puzzling aspects of the paintings is their location. Other rock paintings—for example, those of Bushmen in South Africa—are either located near cave entrances or completely in the open. Cave paintings in France and Spain, however, are in recesses and caverns far removed from original cave entrances.
Why does the author mention Bushmen in South Africa in paragraph 2?
To suggest that ancient artists from all over the world painted animals on rocks
To contrast the location of their rock paintings to those found at Lascaux
To support the claim that early artists worked in cramped spaces
To give an example of other artists who painted in hidden locations
與上一題類似，本題的例子Bushmen in South Africa在原文也有標(biāo)志詞for example，因此這一例子的目的是為了說明它前面的那句話，即這些繪畫的位置令人費(fèi)解。作者以對比的手法來說明這一點(diǎn)：Bushmen in South Africa的繪畫常位于洞口或洞外，而法國和西班牙的洞穴繪畫(本文所說的繪畫)卻位于遠(yuǎn)離最初洞口的深處。由此可見，Bushmen in South Africa的例子是為了說明Lascaux繪畫位置的怪異。第二個選項符合此意，為正確答案。
2.例子與概述合二為一
有時例子與概述合二為一，它們分別出現(xiàn)于從句和主句中，或者出現(xiàn)于同一個分句中。例如，
Scholars offer three related but different opinions about the mysterious origin and significance of these paintings. One opinion is that the paintings were a record of seasonal migrations made by herds. Because some paintings were made directly over others, obliterating them, it is probable that a painting’s value ended with the migration it pictured. Unfortunately, this explanation fails to explain the hidden locations, unless the migrations were celebrated with secret ceremonies.
Why does the author mention secret ceremonies?
To present a common opinion held by many scholars
To suggest a similarity between two opinions held by scholars
To suggest a possible explanation for a weakness in an opinion expressed in the passage
To give evidence that contradicts a major opinion expressed in the passage
問題中的關(guān)鍵詞secret ceremonies出現(xiàn)于段落末句的從句中：unless the migrations were celebrated with secret ceremonies。在同一句子的主句部分，作者指出：不幸的是，這一解釋未能說明為何繪畫的位置要隱蔽…，這等于說這一解釋不能成立；接著在問題所對應(yīng)的從句中補(bǔ)充說明上述解釋成立所必須滿足的條件：除非遷徙的慶祝是秘密進(jìn)行的。這等于說這一解釋缺乏這一條件。第三個選項符合此意，為正確答案。
