Paragraph 1:Rainfall is not completely absent in desert areas,but it is highly variable.An annual rainfall of four inches is often used to define the limits of a desert.The impact of rainfall upon the surface water and groundwater resources of the desert is greatly influenced by landforms.Flats and depressions where water can collect are common features,but they make up only a small part of the landscape.
1.Which of the following statements about annual rainfall can be inferred from paragraph
○ Flat desert areas receive more annual rainfall than desert areas with mountains
○ Areas that receive more than four inches of rain per year are not considered deserts.
○ Many areas receive less than four inches of annual rainfall,but only a few are deserts
○ Annual rainfall has no impact on the groundwater resources of desert areas.

正确答案是B
分析:只需要用到第二句话来解答题目.
根据原文第二句话annual rainfall of four inches是一个标准,我举个例子,类似于每天下五毫米雨那么这个地方就是好地方,每天下的雨都没有五毫米,那么这个地方就是个烂地方.所以,结论来了:超过annual rainfall of four inches的地方就不被定义为desert,不足annual rainfall of four inches就被定义为desert.
为什么C是错的:
它包含了定义没有涉及到得知识,即the context does not contain the information of the choice C.也许有的沙漠降雨量超过了5 inches,也许有的地方根本不下雨它也不是个desert.但是就本文而言,desert没有这么定义的.C是错的.C给出的信息无法根据本文被infer.

IBT TPO12
Paragraph 6:Groundwater is stored in the pore spaces and joints of rocks and unconsolidated (unsolidified) sediments or in the openings widened through fractures and weathering.The water-saturated rock or sediment is known as an "aquifer".Because they are porous,sedimentary rocks,such as sandstones and conglomerates,are important potential sources of groundwater.Large quantities of water may also be stored in lime stones when joints and cracks have been enlarged to form cavities.Most limestone and sandstone aquifers are deep and extensive but may contain ground waters that are not being recharged.Most shallow aquifers in sand and gravel deposits produce lower yields,but they can be rapidly recharged.Some deep aquifers are known as "fossil waters.The term "fossil" describes water that has been present for several thousand years.These aquifers became saturated more than 10,000 years ago and are no longer being recharged.
7.The word fractures in the passage is closest in meaning to
○ streams
○ cracks
○ storms
○ earthquakes

fractures 本意是裂痕,所以是 cracks.
