Migratory songbirds breeding in Eurasia’s temperate forests depend on a summer flush of insects, particularly caterpillars, to feed themselves and their offspring. In some places, these caterpillars are emerging earlier in responses to rising global temperatures.
In theory, the songbird could simply push up their departure from their winter quarters to catch the earlier flush of insect prey.
If, however, the birds rely on a fixed cue such as increasing day length to begin flying north, they may be unable to adjust the timing of their migration. Precisely this disruption in the emergence of insects relative to the timing of songbird migration has been identified as the cause of a significant decline in populations of pied flycatchers in the Netherlands. [br] According to the passage, populations of insects preyed upon by pied flycatchers
选项
A、are finding less food as temperatures rise in the Eurasian forests that they inhabit
B、are endangered because of global warming
C、have recently experienced changes in the timing of their life cycles relative to the calendar
D、have recently begun inhabiting cooler climates largely unfrequented by pied flycatchers.
E、have increased significantly because of lack of predation.
答案
C
解析
文章第五句对应this disruption in the emergence of insects relative to the timing of songbird migration。根据第四句可知,the timing of songbird migration是相对于日照时间的,而日照时间与the calendar保持一致,因此选项C正确。E项根据第五句我们只能知道鸟类减少了,但是不能说虫子一定增多了。这道题的题干是According to the passage,所以文章没提及的不能选。
