再问大全951

1.        A substance from the licorice plant, 50 times sweeter than sucrose, was recently discovered, is not only a natural sweetener but also prevents tooth decay.

(A) A substance from the licorice plant, 50 times sweeter than sucrose, was recently discovered

(B) A substance, which was recently discovered, from the licorice plant, 50 times sweeter than sucrose,

(C) A substance from the licorice plant, which was recently discovered to be 50 times sweeter than sucrose,

(D) A substance from the licorice plant, 50 times sweeter than sucrose , which was recently discovered,（B）

(E) A recently discovered substance, 50 times sweeter than sucrose from the licorice plant,

B的修饰到底怎么处理的？原句意是什么呢？我觉得还可以有两个理解啊：

1）是说A substance was recently discovered 50 times sweeter than sucrose 。其中50 times sweeter than sucrose 做补足语

2）是说A substance was recently discovered from the licorice plant which is 50 times sweeter than sucrose.

自己现在比较倾向1）解释，如果按照2）这样理解是否不应该有逗号夹在from 前，而且50 times 前要有a plant 之类的名词才好啊

晕，望指正

选b啊

我觉得understanding1是对的
