og 188 195

多谢marie JJ的解释，我也和leslie对that/who的用法有项同的疑问。现在知道怎么更好的读OG了。

回leslie：我觉得答案B中容易引起歧义childhood of such infections,即infections是用来修饰childhood的，所以died应该放在句子后面，

我觉得应该分析为

have died [in childhood] of such infection

died of 是习语，意思是死与...

in childhood 修饰died的时间

我到觉得隔开die of 是因为of 后面的词太长了

might once have died
        in childhood
        of
        such infections 中

in childhood插在die of这个词组中，是因为它修饰了die这个动词，意思是在“在孩童时期死于。。。疾病“。

这里绝对不能用as children （作为儿童），否则句子的意思就变成“曾经作为儿童死于。。。疾病”。本题要表达的意思应该是说医学进步了，许多小时候可能死于一些疾病的人，现在可以被治愈并活的很好。而不是说这些人作为儿童就会的得那些病，现在长大了就不会得了。

as children & in childhood 语法都没有错，我觉得根据句意理解是最好的区分方法。

谁知道 once & at one time有什么区别马？

没人看这个题了么？？

还有一个疑点：

为什么用have died，有什么理论根据吗？

died并不是一个持续性动作啊。

根据Longman,

at one time 解释为 at a time in the past but not now
eg.
At one time she wanted to be a nurse, but the thought of working at night put her off.

once (adverb)
第3个解释 at some time in the past, but not now
Sonya and Ida had once been close friends.She and her husband had once owned a house like this.

综上所诉，at one time 和 once　在这个题中是可以通用的。
但是　once 还有其他另外的解释
如

4
in the past, at a time that is not stated
I once ran 21 miles. Marx once described religion as the ‘opium of the people'.

1.ETS可强调句子的美感了，像这种主从句每个elements都平行对称的选项，几乎全部都是正确选项。

2.OG188 

As a result of medical advances, many people who might once have died in childhood of such infections as diphtheria, pneumonia, or rheumatic fever now live well into old age.

you cannot place died after in childhood coz the clause wont parallel to now live well into old age in that case. you cant change the sentence into ...might once have died of such infections....in childhood neither because the phrase of ... is too long  and ETS prefer to put long elements in the end of the sentences.  see OG11 71

......, doubling to twelve
                                    the number of satellites now
known to orbit the distant planet.  normal order should be: double the number to twelve

or OG11 93  …powers enabling it to withhold from the public the
identities of its sources of intelligence information. Normal order should be withhold the
identities from the public.

plus childhood of infections doesnt make any sence, so it is clear that of infections does not modify childhood. 

3. 关于副词形容词改不改的问题，要揣摩原题的意思

像OG 195 seeming unlimited number在美国人眼里完全没意义，摆明了是seemingly unlimited number,所以就要改。

但是OG108 recent extended sales slum 和 recently extended sales slum都 make sense. 所以就尊重原选项的那个意思了。

综上所诉，at one time 和 once　在这个题中是可以通用的。

OG11的新版解释里说at one time is ambiguous and wordy and should be replaced by once
