25题同意选A，

The “mantle plume” thus

      formed, once established, continues to

(40)     channel hot material from the mantle

base until the reservoir is emptied.

流沙

23题题目是It can be inferred from the passage that a chain of volcanoes created by a mantle plume would most likely be characterized by

所以我觉得应该到描述这个东东的地方去找

携隐

我25题一开始也选A,因为对E的core不确定.这个题目出的满刁钻的, 很少有阅读题目的答案跟定位差这么远的.原文对应如下:

L42-43:

The surface mark of an established

plume is a hot spot.

说明hot spot是plume的表面, 也就是题目问的indication

L27-30:

Because of its prox-

imity to Earth’s core, the rock at the

base of the mantle is much hotter than

(30)       rock in the upper mantle.

这里指出plume中的石头是originating near the core的.

ETS变态,出这么难的题啊.

补充:A的base of the mantle不对啊,原文说是surface make

请问24题有没可能是(B)?

我对以下line(46-55)的解读是
line (46-52) : plate movement是a chain of volcanoes or volcanic islands的成因之一；而
line (52-55)的Hawaiian island chain则提供了一个实证,strengthen上述的因果关系

不知道大家是否认为这题答案需要修正？请赐教。

Because the source of a hot
spot remains fixed while a surface
plate moves over it, over a long period
of time an active plume creates a chain
(50)      of volcanoes or volcanic islands, a
track marking the position of the plume
relative to the moving plate.  The natural
history of the Hawaiian island chain
clearly shows the movement of the
Pacific plate over a fixed plume.

25  I chose A first.

However, I found a is incorrect due to the use of untapped

untapped
AHD:[緉-t瞤t揮
D.J.:[(n6t#pt]
K.K.:[(n6t#pt]
adj.
Not having been tapped:
未去塞的：
an untapped cask of wine.
一桶未去塞的酒
Not utilized:
未被利用的：
untapped resources.
未被利用的资源

If the hot rock was untapped, we can not find the hot spot on the surface. Do you agree, open to question.

请教23B中的differ from each other in age,哪里可以看出是in age呀?谢谢

22中的two different mechanisms,文中的第一种mechanism是不是在第一段中讲了?

谢谢nn们的解答

23) B,line48 "over a long period of time an active plume creates a chain of volcanoes or volcanic islands,"

24) E

25) E,A 中“untapped“错。

我也选b了，为什么b不对呢，请教！！！

哈哈，兄弟，咱们犯的是同一个错误。应该都是错误的理解了untapped，我当时选A，就是认为untapped的意思是没加盖儿的，随便儿流的的意思。其实，A除了这一点，和E没有什么区别。
