　　21. T-4-Q5-Q7始祖鸟是从Theropod龙进化而来的么

　　Although many lines of evidence indicate

　　that birds evolved from ground-dwelling

　　theropod dinosaurs, some scientists remain

　　unconvinced. They argue that theropods

　　(5) appeared too late to have given rise to birds,

　　noting that Archaeopteryx lithographica – the

　　oldest known bird – appears in the fossil

　　record about 150 million years ago, where

　　-as the fossil remains of various nonavian

　　(10) maniraptor theropods – the closest known

　　relatives of birds – date only to about 115

　　million years ago. But investigators have

　　now uncovered bones that evidently belong

　　to nonavian maniraptors dating to the time of

　　(15) Archaeopteryx. In any case, failure to find

　　fossils of a predicted kind does not rule out

　　their existence in an undiscovered deposit.

　　Skeptics also argue that the fused clavicles

　　(the “wishbone”) of birds differ from the

　　(20) unfused clavicles of theropods. This

　　objection was reasonable when only early

　　theropod clavicles had been discovered,

　　but fossilized theropod clavicles that look

　　just like the wishbone of Archaeopteryx

　　(25) have now been unearthed. Finally, some

　　scientists argue that the complex lungs of

　　birds could not have evolved from theropod

　　lungs, an assertion that cannot be supported

　　or falsified at the moment, because no fossil

　　(30) lungs are preserved in the paleontological

　　record.

　　C. Theropod fossils dating back more than 150 million years

　　D. Fossils indicating the structure of theropod lungs

　　E. Fossils indicating the structure of Archaeopteryx lungs

　　T-4-Q7

　　Which of the following is mentioned in the passage as an argument made by scientists who are unconvinced that birds evolved from theropod dinosaurs?

　　A. There are no known theropod dinosaur fossils dating from a period after the time of Archaeopteryx.

　　B. There are no known theropod dinosaur fossils that indicate the structure of those dinosaurs’ lungs.

　　C. Theropod dinosaurs appear in the fossil record about 150 million years ago.

　　D. Theropod dinosaurs did not have fused clavicles.

　　E. Theropod dinosaurs had certain bones that look just like those of Archaeopteryx.

　　Skeptics also argue that the fused clavicles (the “wishbone”) of birds differ from the (20) unfused clavicles of theropods.
