GWD28-28想不明白谢谢拉

支持C

1,Fill题,关键看前一句,也就是"therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils," 

即:the herb’s high histidine production-> herb grow in metal-rich soils

C.     others of the closely related group of plants are also found to produce histidine in
                            large quantities

 

 

2.另外, 对前几楼有人提出的"这个closely related group of plants不知道生长的什么土壤中",

 

我的反驳是: 文中的背景信息:A certain cultivated herb is one of a group of closely related plants
                            (that thrive in soil with high concentrations of metals) that are toxic to most other plants. 所以已经说明了这个Plants是生长在高浓度金属的土壤中的

 

Open to discuss

支持C。关键是第一句：

A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. 

长在土里的不是这一种被测试的植物，而是一组植物。

以下是引用gonghao在2006-8-6 18:01:00的发言：

closely related group of plants

is used to modify the such plants which similar to herb,that's all it's fuction.

举个例子：玫瑰分泌出一种香味，使得人们心花怒放。需要support的是结论：香味使得人们心花怒放。

C相当于：其他的和玫瑰同科属的花也散发相同的大量的香味。

明显：无法说明香味是否使得人们心花怒放。

Plz note it is "the closely related group of plants", I guess it should refer to "a group of closely related plants", which includes the cultivated herb, in the arg.
