UNIT 5 课时检测（四） “Developing ideas”的课文习读环节 Ⅰ.阅读理解 A For the first time, a causal link has been established between climate change and the timing of a natural event — the appearance of the common brown butterfly. Although there have been strong connections between global warming and changes in the timing of events such as animal migration and flowering, it has been hard to show a cause－and－effect link.This is what Michael Kearney and Natalie Briscoe of the University of Melbourne, Australia, have now done. The researchers compared temperature changes in Melbourne — where the butterfly is common — with recorded observations of the first brown butterfly to be seen in the spring since the 1940s.With each of the past ten years, the butterflies appeared 1.6 days earlier and Melbourne heated by 0.14℃.Overall, the butterfly now appears on average 10.4 days before it did in the 1940s. The pair are confident in the relationship for two reasons.First, they placed eggs of the butterfly, in special boxes where temperature could be controlled and found that each larval stage had a different response to warmerthannormal conditions.The egg, which is laid in late summer, and the first larval stage do well at high temperatures, says Kearney.The second to the fifth stages occur in winter and can't survive high temperatures.The_knock－on_effect is that the larval pupates earlier and the butterfly appears sooner.Second, they made a mathematical model combining these physiological effects of temperature on development with climate data.The model precisely matched the observed changes in butterfly emergence date. The researchers used several climate models to find out what is likely to have caused the rise in Melbourne's temperature, and ruled out the possibility that natural weather events could account for the warming. 语篇解读：本文是一篇说明文。文章主要介绍了随着气候的改变，动物的习性也会有所改变。蝴蝶出现得比以往早，就是因为气候变暖。 1．What is the relationship between the rise in temperature and the butterfly appearance? A．They are linked i
