Paragraph 3 If true, though, why did cold-blooded animals such as snakes, lizards, turtles, and crocodiles survive the freezing winters and torrid summers? These animals are at the mercy of the climate to maintain a livable body temperature. It’s hard to understand why they would not be affected, whereas dinosaurs were left too crippled to "cope", especially if, as some scientists believe, dinosaurs were warm-blooded. (不會換色用" " 請見諒@@) 4. The word cope in the passage is closest in meaning to ○adapt ○move ○continue ○compete 答案給A 我選D 應該是給錯了? 查不到adapt的意思囧另外順便另一題 Paragraph 4 Dissatisfaction with conventional explanations for dinosaur extinctions led to a surprising observation that, in turn, has suggested a new hypothesis. Many plants and animals disappear abruptly from the fossil record as one moves from layers of rock documenting the end of the Cretaceous up into rocks representing the beginning of the Cenozoic (the era after the Mesozoic). Between the last layer of Cretaceous rock and the first layer of Cenozoic rock, there is often a thin layer of clay. Scientists felt that they could get an idea of how long the extinctions took by determining how long it took to deposit this one centimeter of clay and they thought they could determine the time it took to deposit the clay by determining the amount of the element iridium (lr) it contained. 8. In paragraph 4, all the following questions are answered EXCEPT: ○Why is there a layer of clay between the rocks of the Cretaceous and Cenozoic? ○Why were scientists interested in determining how long it took to deposit the layer of clay at the end of the Cretaceous? ○What was the effect of the surprising observation scientists made? ○Why did scientists want more information about the dinosaur extinctions at the end of the Cretaceous? 有板友可以幫忙解釋一下嗎 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.36.185.112
