GWD9  Q33-36

Q33 to Q36:

Scientists studying the physiology

of dinosaurs have long debated whether

dinosaurs were warm- or cold-blooded.

Line Those who suspect they were warm-

(5) blooded point out that dinosaur bone

is generally fibro-lamellar in nature;

because fibro-lamellar bone is formed

quickly, the bone fibrils, or filaments, are

laid down haphazardly. Consistent with

(10) their rapid growth rate, warm-blooded

animals, such as birds and mammals,

tend to produce fibro-lamellar bone,

whereas reptiles, which are slowgrowing

and cold-blooded, generally

(15) produce bone in which fibrils are laid

down parallel to each other. Moreover,

like the bone of birds and mammals,

dinosaur bone tends to be highly

vascularized, or filled with blood

(20) vessels. These characteristics,

first recognized in the 1930’s,

were documented in the 1960’s by

de Ricqlès, who found highly vascularized,

fibro-lamellar bone in several

(25) groups of dinosaurs. In the 1970’s,

Bakker cited these characteristics as

evidence for the warm-bloodedness of

dinosaurs. Although de Ricqlès urged

caution, arguing for an intermediate type

(30) of dinosaur physiology, a generation of

paleontologists has come to believe

that dinosaur bone is mammalianlike.

In the 1980’s, however, Bakker’s

contention began to be questioned, as a

(35) number of scientists found growth rings

in the bones of various dinosaurs that

are much like those in modern reptiles.

Bone growth in reptiles is periodic in

nature, producing a series of concentric

(40) rings in the bone, not unlike the growth

rings of a tree. Recently, Chinsamy

investigated the bones of two dinosaurs

from the early Jurassic period

(208-187 million years ago), and found

(45) that these bones also had growth rings;

however, they were also partially fibrolamellar

in nature. Chinsamy’s work

raises a question central to the debate

over dinosaur physiology: did dino-

(50) saurs form fibro-lamellar bone because

of an innately high metabolic rate associated

with warm-bloodedness or

because of periods of unusually fast

growth that occurred under favorable

(55) environmental conditions? (Although

modern reptiles generally do not form

fibro-lamellar bone, juvenile crocodiles

raised under optimal environmental

conditions do.) This question remains

(60) unanswered; indeed, taking all the evidence

into account, one cannot make

a definitive statement about dinosaur

physiology on the basis of dinosaur

bone. It may be that dinosaurs had an

(65) intermediate pattern of bone structure

because their physiology was neither

typically reptilian, mammalian, nor avian.

Q33:

The author of the passage would be most likely to agree that the “caution” (line 29) urged

by de Ricqlès regarding claims about dinosaur physiology was

A. unjustified by the evidence available to de Ricqlès

B. unnecessary, given the work done by Bakker and his followers

C. indicative of the prevailing scientific opinion at the time

D. warranted, given certain subsequent findings of other scientists

E. influential in the recent work of Chinsamy

答案是D，我第一次作时选的也是D。但后来有人给我的答案是A，我仔细想了一下，A也蛮有道理的。不知A、D哪个好？

D.是说，后来发现的rings证明了de Ricqlès 说的 “caution” 是对的。但关键在warranted这个词上，de Ricqlès 说 “caution”时，还没有具体的依据，他只是可能料到以后会有新的发现来推翻他的观点。所以，若wanrranted翻译为“有依据的”那D就不对；但若wanrranted翻译为“有道理的”，那D就是对的。关键在对wanrranted这个词的理解上，应该如何理解？同理，A里的unjustified也是不知该如何翻译？若是“未被证明的”则A对，若是“没有道理的”则A不对。

极疑惑！请NN和版主们指点！！

D is obviously the right answer.

The question asks "The author of the passage would be most likely to agree that ...".  To answer the question, you need to pay attention to the overall tone of the author.  Although sometimes the meaning of one or two keyword(s) is crucial, but not necessarily in this type of global inference question.  Looking from this angle, you will see that D is obviously the best answer.

我认为应该选A。因为caution不是作者提出的，而是de Ricqlès urged的，作者同意这个caution应该只是同意那个人觉得还没有被证实的观点，而不是将来以后被别人证实的观点。 请指正！！

PS. youpiao mm 你这个看上去很想word的版本哪里来的啊？能不能给我一份啊?

不同意 如你所讲的 作者同意这个caution  但这题问的是作者对于这caution的态度  如果他认为unjustified 怎么会同意呢?

我想问一下这里 D 的given是形容warranted吗 因为这样理解才make sense 但又不是很确定

顺便问一下34

Q34:
The primary purpose of the passage is to
A. discuss the influence on other scientists of Bakker’s argument concerning the
warm-bloodedness of dinosaurs
B. provide evidence that supports the claim that dinosaurs were cold-blooded
C. challenge the contention that dinosaur bone tissue is innately fibro-lamellar
D. evaluate the claim that dinosaur bone tissue provides evidence for the warmbloodedness
of dinosaurs
E. resolve the disagreement between de Ricqlès and Bakker over the nature of
dinosaur physiology

我在A D之间不知怎么取舍

请教一下 谢谢!!

Can you explain how you exclude A , thanks !!

33题，the caution 到最后也没被 warranted 过，只是 may be, remains unanswerd.怎么选D?

回答9楼！这道题是问作者的观点读读最后一句！会读出态度的！
