1.

原文如下：Researchers of the Pleistocene epoch have developed all sorts of more or less fanciful model schemes of how they would have arranged the Ice Age had they been in charge of events. For example, an early classification of Alpine glaciations suggested the existence there of four glaciations, named the Gunz, Mindel, Riss, and Wurm. This succession was based primarily on a series of deposits and events not directly related to glacial and interglacial periods, rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits. Yet this succession was forced willy-nilly onto the glaciated parts of Northern Europe, with hopes of ultimately piecing them together to provide a complete Pleistocene succession. Eradication of the Alpine nomenclature is still proving a Herculean task.

Question8. Which of the following does the passage imply about
the ―early classification of Alpine glaciation‖ ?
(A) It should not have been applied as widely as
it was.
(B) It represents the best possible scientific practice,
given the tools available at the time.
(C) It was a valuable tool, in its time, for measuring
the length of the four periods of glaciation.
(D) It could be useful, but only as a general guide
to the events of the Pleistocene epoch.
(E) It does not shed any light on the methods used
at the time for investigating periods of glaciation

正确答案是A，我选的是D。觉得这两个皆可啊，D错在哪里了？


2. 题目如下：Which of the following most logically completes the
argument?
Alivia‘s government has approved funds for an electricity-generation project based on the construction of a pipeline that will carry water from Lake Cylus, in the mountains, to the much smaller Lake Tifele, in a nearby valley. The amount of electricity generated will be insufficient by itself to justify the project‘s cost, even if the price of imported oil-Alivia‘s primary source of electricity-increases sharply. Nonetheless, the pipeline project is worth its cost, because ——

(A) the price of oil, once subject to frequent sharp increases, has fallen significantly and is now fairly stable
(B) the project could restore Lake Tifele, which is currently at risk of drying up and thus of being lost as a source of recreation income for Alivia
(C) the government of Alivia is currently on excellent terms with the governments of most of the countries from which it purchases oil
(D) it would cost less to generate electricity by moving water from Lake Cylus to lake Tifele than to do so by moving water from Lake Cylus to another valley lake
(E) Alivian officials do not expect that the amount of electricity used in Alivia will increase substantially within the next ten years

这道题正确答案是D，但是觉得B也很对啊，增加收入不也是一种好处么？
