  在这一节前面很多内容都是关于纯语法的内容，但是SAT的语法考试是在一篇文章里挖掘一些考点进行测试的，因此不免还会遇到一些考查单词意思的题目。

  一些常用的近义词要搞清楚，尤其是在意思上细微的差距。

  例题1

  As fun as it is to have company, my best hunts have been solitude trips.

  A. NO CHANGE

  B. solitarily

  C. solitaire

  D. solo

  解析1

  B是副词不可以用来修饰名词

  AC确实是表示单独的，但是不好

  D中solo trip用来表示搭配单程

  因此D

  例题2

  Forten’s knowledge of ships, gained from his experiences as a sailor during the war, paid off. He rose to the position of foreman, and in 1798. Forten bought the sailmaker’s business.

  A. NO CHANGE

  B. had arose

  C. had rose

  D. raised

  解析2

  BC时态错误，整个句子都是一般过去时态，句子中没有任何语言标志的词可以表达完成时态。

  AD在意思上差距还是很大的，只是拼写类似。

  因此A

  除了动词之外，我们还应该关注的是动词相关的变化，如过去式和过去分词。此外我们还需要关注一些形容词和副词的辨析。

  本节练习

  Uncovered at Johnson’s Shut-Ins

  In Reynolds County, Missouri, a one-billion-gallon blast of [1]water caused by a breach of the Taum Saunk reservoir roared down Proffit Mountain into the east fork of the Black River on December 14, 2005. [2]They ripped a channel through Johnson’s Shut-Ins, one of Missouri’s most popular state parks. Though flood damage marred the [3]parks beauty for a time, the scar the raging water left in its wake [4]specifically revealed over a billion years’ worth of Earth’s geologic history.

  The area known today as Johnson’s Shut-Ins State Park [5]had began to develop 1.5 billion years [6]ago. When the volcanoes that created the St. Francois Mountains exploded. Slow-moving magma [7]cooled down its temperature and crystallized to [8]form silica-rich rhyolite rock. Over time sedimentary rock such as limestone and shale, formed from material deposited by shallow inland seas, buried the rhyolite. After the seas had receded, gravel-rich rivers and streams eventually chipped away the soft sedimentary rock in some areas, exposing the erosion-resistant rhyolite rock and creating pockets and pits. In low places, the Black River was confined ([9]or ”shut in”) by the [10]rhyolite and creating the natural waterslides and canyon-like gorges that have become a summer playground for thousands of visitors.

  Although the flood left the shut-ins unscathed, the surge of water that tore through the park in 2005 stripped away all trees, soil, and sedimentary rock [11]in its path. Left behind is a channel that is composed of granite –and previously unexposed rhyolite rock- and [12]contain rocks from at least three other geological eras. The menacing floodwaters also revealed a half-billion-year-old beach made of both sand and gravel.

  Five years of work has restored most of the park surrounding the shut-ins. [13]Some have returned [14]back. Geologists from around the world visit to get a close look at the ancient volcanic rock along what has been named the “Scour Channel”. The “Scour Channel” now rivals the park’s other geologic curiosities for most frequently visited site.
