托福阅读句子插入题和托福阅读句子简化题是一对“好兄弟”，前者考查句子间逻辑，大家需要按照句子前后的关联词来解题，后者考查句子内部的逻辑，一般情况下需要根据逻辑词来解题。但是两者最大的共性在于两者解题过程都不会很纠结。下面前程百利小编来细数一下那些年遇到的超级简单的托福阅读句子插入题，来看一下这种题型。
例1来自TPO37 Stream Deposits
Paragraph 4: A stream also slows abruptly where it enters the still water of a lake or ocean. The sediment settles out to form a nearly flat landform called a delta. Part of the delta lies above water level, and the remainder lies slightly below water level. Deltas are commonly fan-shaped, resembling the Greek letter delta (!〇). Both deltas and alluvial fans change rapidly. Sediment fills channels (waterways), which are then abandoned while new channels develop as in a braided stream. As a result, a stream feeding a delta or fan splits into many channels called distributaries. A large delta may spread out in this manner until it covers thousands of square kilometers. ■Most fans, however, are much smaller, covering a fraction of a square kilometer to a few square kilometers. ■The Mississippi River has flowed through seven different delta channels during the past 5,000 to 6,000 years. ■But in recent years, engineers have built great systems of levees (retaining walls) in attempts to stabilize the channels. ■
Look at the four squares [■] that indicate where the following sentence could be added to the passage.Where does the sentence best fit?
If the Mississippi River were not contained by such systems，it would probably abandon its present path and cut into the channel of a nearby river to the west.
解析：答题关键在于“such systems”，看到只有在最后一句出现了关键词“systems”，所以选择第四个插入口。
例2来自TPO19 Discovering the Ice Ages
Paragraph 1: In the middle of the nineteenth century, Louis Agassiz, one of the first scientists to study glaciers, immigrated to the United States from Switzerland and became a professor at Harvard University, where he continued his studies in geology and other sciences. For his research, Agassiz visited many places in the northern parts of Europe and North America, from the mountains of Scandinavia and New England to the rolling hills of the American Midwest. ■ In all these diverse regions, Agassiz saw signs of glacial erosion and sedimentation.■ In flat plains country, he saw moraines (accumulations of earth and loose rock that form at the edges of glaciers) that reminded him of the terminal moraines found at the end of valley glaciers in the Alps. ■ The heterogeneous material of the drift (sand, clay, and rocks deposited there) convinced him of its glacial origin. ■
Look at the four squares (HI that indicate where the following sentence could be added to the passage
In his view, there could be no other explanation for the composition of such drift
Where would the sentence best fit?
解析：根据such drift，在原文中只找到在最后一句出现drift，所以答案是第四个插入口。
好了，以上就是前程百利小编为考生到带来的那些年遇到的超级简单的托福阅读句子插入题。除了这种可以只根据一个解题线索词就能够解题的题目之外，一般的托福阅读句子插入题都会有2-3个解题线索，但是也不会太难。所以希望考生可以在做题过程中多总结。预祝大家托福考试取得好成绩!
