补充250中218

regine

The domesticated camel, which some scholars date around the twelfth century B.C., was the key to the development of the spice trade in the ancient world.

(A) The domesticated camel, which some scholars date

(B) The domesticated camel, which some scholars having thought to occur

(C) Domesticating the camel, dated by some scholars at

(D) The domestication of the camel, thought by some scholars to have occurred


(E) The camel’s domestication, dated by some scholars to have been


为什么选择D

weiyu

是camel产生了development of spice trade还是domestication产生了development of spice trades. 逻辑意思可以马上判断;


E的被动语态不太好.(其它错误由NN解释吧?)

1.答案D中，thought跟在camel后不会有歧义吗？如果没有歧义C为何不行？

2.E中的domestication作为不定式的形式主语其实就是domestication have been around the twelfth century B.C有何不可？我们不是常说we've been there many times.吗？

3.原句的意思是some scholars date D的意思是some scholars thought这是不是改变了原意了呢？

请教。

1. The camel 不能是 the key development, 而 the domestication 是 key development,  A, B不对

2. domesticating 表示持续动作， C 不对

3  E 中, been 后不完整, ie.  domestication dated by some scholars to have been.... around 12th century B.C.

4. D is right.
