对两道语法题用法的疑惑

心静

1)Personal trainers and fitness coaches are to the narcissistic 1980's just like a private fencing master and dancing teacher was to an earlier time.

c)what private fencing masters and dancing teachers were
问题：选C，但总觉得这种形式有问题，what前应该加 like才对吧。

2)The domesticated camel , which some scholars date around twelfth century B.C, was the key to the development of the spice trade in the ancient time.
c)Domesticating  the camel , dated by some scholars
d)The domestication of  the camel , thought by some scholars to have occured
问题：选D，可C好象语法也没错呀，而且更简洁，是不是因为文中的“ the key ”，所以一定要对应名词形式呢？好象没有这种硬性规定吧？

来路不明的题，最好少做。否则干扰思维习惯，弊大于利呢......

lyricling

第一题是语法结构是A be to B what C be to D。该题在以前的贴子里出现过。

第二题主要是从意思上去理解。动作性名词表结果，而动名词表动作。你说是这个动作be key to the development of the spice trade in the ancient time呢还是驯养骆驼这个结果be key to the development 呢？

补充一点:
第二题,C中,dated修饰什么?从逻辑意思上是修饰Domesticating  the camel ,从语法中只能修饰teh camel.所以错.

其它同意lyricling!!!

Commonly,the parenthesis set off by commas in describes the subject or the key word of a sentence.In B,  the subject "Domesticating  the camel " cannot be logically modified by  "dated by scholars" ,thus it generates difficulty in the meaning of the sentence.
