第二篇的第一题：
Paragraph 1：The vast grasslands of the High Plains in the central United States were settled by farmers and ranchers in the 1880’s. This region has a semiarid climate, and for 50 years after its settlement, it supported a low-intensity agricultural economy of cattle ranching and wheat farming. In the early twentieth century, however, it was discovered that much of the High Plains was underlain by a huge aquifer (a rock layer containing large quantities of groundwater). This aquifer was named the Ogallala aquifer after the Ogallala Sioux Indians, who once inhabited the region.

1．According to paragraph 1, which of the following statements about the High Plains is true?
○Until farmers and ranchers settled there in the 1880’s, the High Plains had never been inhabited.
○The climate of the High Plains is characterized by higher-than-average temperatures.
○The large aquifer that lies underneath the High Plains was discovered by the Ogallala Sioux Indians.
○Before the early 1900’s there was only a small amount of farming and ranching in the High Plains.

我选的A  后来才发现   有绝对词  而且  确实没有说他们是第一批的 settlers
答案是D   请问D选项 怎么能判断出来是 a small amount的？而且 他也有only啊！！！绝对词 有没有！！！
求各位指导哈！！！

再来一个问题，同一篇的第三题
The Ogallala aquifer is a sandstone formation that underlies some 583,000 square kilometers of land extending from northwestern Texas to southern South Dakota. Water from rains and melting snows has been accumulating in the Ogallala for the past 30,000 years. Estimates indicate that the aquifer contains enough water to fill Lake Huron, but unfortunately, under the semiarid climatic conditions that presently exist in the region, rates of addition to the aquifer are minimal, amounting to about half a centimeter a year.

Question：Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
○Despite the current impressive size of the Ogallala aquifer, the region’s climate keeps the rates of water addition very small.
○Although the aquifer has been adding water at the rate of only half a centimeter a year, it will eventually accumulate enough water of fill Lake Huron.
○Because of the region’s present climatic conditions, water is being added each year to the aquifer.
○Even when the region experiences unfortunate climatic conditions, the rates of addition of water continue to increase.

红字部分的理解 为什么是A ？

The vast grasslands of the High Plains in the central United States were settled by farmers and ranchers in the 1880’s.

选项D中的“only a small amount of” 是针对文章第一句中“vast”的反义改写。

Estimates indicate that the aquifer contains enough water to fill Lake Huron, but unfortunately, under the semiarid climatic conditions that presently exist in the region, rates of addition to the aquifer are minimal, amounting to about half a centimeter a year。

该句子相当于 but连接的两个句子，主要是强调but之后的句子内容，你可以看作 A but B ，主要说B的内容
在所有选项中强调B内容（即rates of addition to the aquifer are minimal；其中minimal=very small）只有选项A

不知我这么解释，是否清楚，希望T友们补充

这个反义改写 是不是有点太含蓄太隐晦了吧？？不过 貌似 是和那个  small 有关系。。。。。
我后来又仔细看了下 会不会是 最后一句中“named after the indians，who inhabit this region”的“indians”代表了 选项中  a small amount of 啊？？？？
