GWD24，骨折照x-ray的那道题，偶觉得选C吧。答案给的B，跟题目没关系啊……哪位NN指点一下吧，谢谢

24-22 Often
patients with ankle fractures that are stable, and thus do not require surgery,
are given follow-up x-ray because their orthopedists are concerned about
possibly having misjudged the stability of the fracture. When number of
follow-up x-rays were reviewed, however, all the fractures that had initially
been judged stable were found to have healed correctly. Therefore, it is a
waste of money to order follow-up x-rays of ankle fracture initially judged
stable.

Which of the
following, if true, most strengthens the argument?

A)   
Doctors who are general practitioners
rather than orthopedists are less likely than orthopedists to judge the
stability of an ankle fracture correctly.

B)   
Many ankle injuries for which an
initial x-ray is ordered are revealed by the x-ray not to involve any fracture
of the ankle.

C)   
X-rays of patients of many different
orthopedists working in several hospitals were reviewed.

D)   
The healing of ankle fractures that
have been surgically repaired is always checked by means of a follow-up x-ray.

E)   
Orthopedists routinely order follow-up
x-rays for fractures of bone other than ankle bones.

B,

如果最初的光测试说明哪些受伤的人的骨头根本就没有fracture,则不会引起矫正问题，也没有必要进行follow-up x-rays

C,说明不同医院的不同骨科医生做的X光,都发现原来诊断正确,加强了结论,即:在这种情况下(fracture stable),没有必要再做X光.

B是无关选项.题目针对的是踝骨骨折STABLE的病人.

X-rays of patients of many different
orthopedists working in several hospitals were reviewed

C,说明不同医院的不同骨科医生做的X光,都发现原来诊断正确,

好像没有表达出这层意思来呀：《

When number of
follow-up x-rays were reviewed, however, all the fractures that had initially
been judged stable were found to have healed correctly. ,

在C选项中,提到

X-rays of patients of many different
orthopedists working in several hospitals were reviewed.

如果C成为条件之一,那么就说明,all the fractures that had initially
been judged stable were found to have healed correctly. ,

这个现象不是在个别医院或者是某一个医生那里才出现,而是有普遍性的.

以此我认为C作为条件会加强结论

I vote for C. B is irrelevant.

X-rays of patients of many different
orthopedists working in several hospitals were reviewed.

几家不同医院的多个不同医生的病人的X-rays被检验，并不能推出具有完全的普遍性

如果C成为条件之一,那么就说明,all the fractures that had initially
been judged stable were found to have healed correctly. ,

这个现象不是在个别医院或者是某一个医生那里才出现,而是有普遍性的.

虽然B也不好，主要是many引起的，但我还是优先考虑这个

倒~我当削弱做的,选了个B~~现在才发现是要加强!弄明白了~

B:Many ankle injuries for which an
initial x-ray is ordered are revealed by the x-ray not to involve any fracture
of the ankle.这个只是伤,并没有确诊为骨折,所以这些尚未被确诊的伤也被要求做X-RAY,违背了原文的一个大前提patients with ankle fractures are given follow-up x-ray (第一句话),再加上这些伤最终被认定为非骨折,所以就没必要了,加强结论!

D) The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.

外科治疗的脚踝骨折总是要经过follow up 的x光减查啊，既然以后难免要x检查，不就说明第一次没用么
