[求助]大全16-1

1. The chanterelle, a type of wild mushroom, grows beneath host trees such as the Douglas fir, which provide it with necessary sugars. The underground filaments of chanterelles, which extract the sugars, in turn provide nutrients and water for their hosts. Because of this mutually beneficial relationship, harvesting the chanterelles growing beneath a Douglas fir seriously endangers the tree.

Which of the following, if true, casts the most doubt on the conclusion drawn above?

(A) The number of wild mushrooms harvested has increased in recent years.

(B) Chanterelles grow not only beneath Douglas firs but also beneath other host trees.

(C) Many types of wild mushrooms are found only in forests and cannot easily be grown elsewhere.

(D) The harvesting of wild mushrooms stimulates future growth of those mushrooms.D

(E) Young Douglas fir seedlings die without the nutrients and water provided by chanterelle filaments.

我选得是E,为什么D,难道我把句意理解错了吗?

说说你为什么选E吧?你是不是把问题理解反了?原文结论是不能收割在D下的C,题目问

DOUBT原文结论的选项,也就是让你找可以收割在D下的C的理由,当然是D了,E是支持原文结论

的.
