易错题解析：
Paragraph 2: Generally speaking, the interiors of plates are geologically uneventful. However, there are exceptions. A glance at a ma of the Pacific Ocean reveals that there are many islands far out at sea that are actually volcanoes----many no longer active, some overgrown with coral----that originated from activity at points in the interior of the Pacific Plate that forms the Pacific seafloor.
3.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
O Volcanic activity is responsible for the formation of the Pacific seafloor in the interior of the Pacific Plate.
O Many volcanoes in the Pacific Ocean are no longer active and have become islands that support coral.
O There are many islands in the Pacific Ocean that originated as volcanoes in the interior of the Pacific Plate.
O The map of the Pacific Ocean reveals fewer volcanic islands than there truly are because many are no longer active and some are completely overgrown with coral.
题型：句子简化题。答案是(C)
解析：根据这一段的第一句可以看出后面是在举例说内陆平静的exception。A，B，D选项都是句子的细节部分，不能表达出其目的。所以正确答案是C。
Paragraph 3: How can volcanic activity occur so far from a plate boundary? The Hawaiian islands provide a very instructive answer. Like many other island groups, they form a chain. The Hawaiian Islands Chain extends northwest from the island of Hawaii. In the 1840s American geologist James Daly observed that the different Hawaii islands seem to share a similar geologic evolution but are progressively more eroded, and therefore probable older, toward the northwest. Then in 1963, in the early days of the development of the theory of plate tectonics. Canadian geophysicist Tuzo Wilson realized that this age progression could result if the islands were formed on a surface plate moving over a fixed volcanic source in the interior. Wilson suggested that the long chain of volcanoes stretching northwest from Hawaii is simply the surface expression of a long-lived volcanic source located beneath the tectonic plate in the mantle. Today’s most northwest island would have been the first to form. They as the plate moved slowly northwest, new volcanic islands would have forms as the plate moved over the volcanic source. The most recent island, Hawaii, would be at the end of the chain and is now over the volcanic source.
6.In paragraph 3, what is the relationship between the scientific contribution of James Daly and Tuzo Wilson?
O Wilson provided an explanation for the observations made by Daly.
O Wilson challenged the theory proposed by Daly.
O Wilson found numerous examples of island chains that supported Daly’s theory.
O Wilson popularized the explanation of volcanic island formation formulated by Daly
题型：推论题。答案是(A)
解析：根据两个科学家的名字进行定位。从then in 1963这一句可以了解到两者关系，说在板块理论刚开始发展的时期，tuzo Wilson发现……那么肯定是使板块理论进一步发展了。所以B不对。而C虽然逻辑关系对，但文中只给了夏威夷岛一个例子。所以C不选。D说使解释流行，之前daly只是给了理论，并没解释，所以不对。只有A既符合逻辑关系，对wilson的描写也是正确的。
