1.  Bob Wilber becames Sidney Becht's student and protege when he was nineteen and , for a few years in the 1940's , came as close to being a carbon copy of the jazz virtuoso in performanc as anyone has ever come.
a. as anyone has ever come
b. as anyone ever had been
c. as anyone ever had done
d. that anyone ever did
e. that anyone ever came
答案：a
lzm 解释说 has ever come 中的ever 只能放在 has 之后， c 中 ever 在had 后， 所以c 不对，请问 ever 的位置是一定的吗？

2.   New techniques in thermal-scanning photography, a process that records radiation from surface areas, makes it possible to study the effects of calefactions, or warming, of a river in greater detail than ever before.

e. has made it more possible than ever before to studyin greater detail the effects of calefactions, or warming, of a river.
答案：c.
我的问题是 1) a中的 in greater detail 可不可以理解为修饰 river.
                2) b中的 in greater detail 可不可以理解为既 修饰 study , 又可能修饰 the
                    effects, 导致修饰混乱， 所以b 错误。     
               3）ever 出现可以不用完成时态 吗？

d. failure to advertise as prominently the highest price in a range of prices for a service or product as the lowest  
e. failing to advertise as prominently the highest price in a range of prices for a service or product  as that of  the lowest  
答案：c
我的问题是：d 的表达为什么不如 c， prominently 作为状语 紧跟动词 advertise 呀？

别的不敢说，但has/HAD与 ever一同出现的时候，ever应该在后面。
但C与A还是时态的差异，关于A为什么用现在完成时，可以参考一下以前的讨论。

回答第二题：

这题的关键是than ever before用现完。所以可以排除其他选项。主语为复数。

in greater detail程度副词短语，只能修饰study。修饰名词解释不通。

第三题搜索以前的讨论。

3. as prominently as 在一起意思清晰，D中将谓语动词advertise和名词分割
事实上 as + adv. + n. + as 的用法都不好；    as + adj. + n. + as  倒还有用的

1, since it refers to ANYONE, there is no time frame, so past ferfect is improper
2, in addition to shelly's explanation, i think choice B is a broken sentence, shouldn't be prioritized.
3, i would argue it should be analyze from meaning point of view. we all know that retailers always prominently advertise lowest prices to attract customers. so it makes more sence to stick the word 'PROMINENTLY' to 'lowest prices.'

这位大侠，你能使用点中文吗？因为我看你的英文总是很吃力，更不用说深入理解和学习。
万分感谢
