1. The primary purpose of the passage is to 【W(wǎng)HY】
2. Which of the following best characterizes the organization of the passage as a whole??【HOW】
3. According to the passage, Farmer?concedes?that endothermy provides an explanation for which of the following?features shared?by birds and mammals??【W(wǎng)HAT】
文章講解:
①Many researchers attribute the large number of physiological and behavioral similarities between birds and mammals, which have separate evolutionary histories, to endothermy (a thermoregulatory strategy whereby warm body temperature is maintained through internal heat sources). ②However, Farmer argues that parental care rather than endothermy is the key to understanding the similarities between mammals and birds. ③According to Farmer, while endothermy provides an explanation for a few similarities, such as the presence of body insulation, endothermy is just one characteristic among many related to parental care. ④The two purported advantages of endothermy that have been most frequently cited by researchers are an expanded range of inhabitable environments and the ability to sustain vigorous exercise. ⑤But metabolism has to increase substantially (at great energy cost) therefore conferring any significant thermoregulatory advantage in terms of the former, and there is no causal biological linkage to explain why endothermy would be essential to sustain exercise. ⑥Farmer argues instead that endothermy evolved as a means to control incubation temperature and that the ability to sustain exercise evolved separately, as a means to improve a parent’s ability to forage and?provision?its young.?
