题目解析:
In any case, failure to find fossils of a predicted kind does not rule out their existence in an undiscovered deposit.由此可知fossils of a predicted kind是没有成功找到的化石类型。我们已经发现的有晚于鸟的恐龙化石以及与鸟同时期的恐龙化石,所以还没有发现的就是比鸟更早的恐龙化石。因此答案为C。
3.Which of the following is mentioned in the passage as an argument made by scientists who are unconvinced that birds evolved from theropod dinosaurs?
问科学家的看法
A. There are no known theropod dinosaur fossils dating from a period after the time of Archaeopteryx.
错误。科学家发现的恐龙化石就是在鸟之后的。
B. There are no known theropod dinosaur fossils that indicate the structure of those dinosaurs’ lungs.
错误。这是我们刚才识别的作者视角。
C. Theropod dinosaurs appear in the fossil record about 150 million years ago.
错误。发现与鸟同时期的恐龙化石的是investigators。
D. Theropod dinosaurs did not have fused clavicles.
正确。对应:Skeptics also argue that the fused clavicles (the “wishbone”) of birds differ from the unfused clavicles of theropods.
E. Theropod dinosaurs had certain bones that look just like those of Archaeopteryx.
错误。科学家们一定是觉得恐龙与鸟有差异,而不是look just like的关系。
