托福阅读词汇题考察的是词汇在文章中特定语境下的含义，所以词汇的含义一定是适合语境的。所以在不少的托福阅读词汇题解题技巧中，我们可以看到“猜词”这个字眼。但是，经过一些实践之后，前程百利小编想说，出题者设计的词汇题难度不一，托福阅读词汇题仅仅依靠猜词会有风险。
举几个托福阅读词汇题的例子，大家感受一下这些题目的难度：
例一：
Paragraph 1: Earth’s surface is not made up of a single sheet of rock that forms a crust but rather a number of “tectonic plates” that fit closely, like the pieces of a gain jigsaw puzzle. Some plates carry islands or continents, others form the seafloor. All are slowly moving because the plates float on a denser sem-iliquid mantle, the layer between the crust and Earth’s core. The plates have edges that are spreading ridges (where two plates are moving apart and new seafloor is being created), subduction zones (where two plates collide and one plunges beneath the other), or transform faults (where two plates neither converge nor diverge but merely move past one another). It is at the boundaries between plates that most of Earth’s volcanism and earthquake activity occur.
2. The word “converge” in the passage is closest in meaning to
O expand
O form
O rise
O move closer
解析：单词所在句子为“…or transform faults (where two plates neither converge nor diverge but merely move past one another).”括号内是解释转换断层的，在那里两个板块既不是converge也不是diverge，而是经过对方。根据这里converg和diverge的并列关系，根据neither … nor …,diverge是分开，converge是相反的概念。所以选项D正确。
这个题目根据句子中的并列关系进行推导，可以正确地猜出词义，而且题目选项的设置没有干扰选项。
例二：
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.
5. The word “eroded” in the passage is closest in meaning to
O worm down
O scattered
O developed
O deserted
解析：单词所在句子为“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.”意思是：在十八世纪40年代，地质学家James Daly观察到不同的夏威夷岛屿看起来经历了相似的演变过程，但它们所受腐蚀一个比一个严重，所以越往西北方向的岛屿形成时间可能越早。这里的erode肯定是个geologic evolution，地质过程，所以选项A正确。
这个题目可以根据句子表述内容相关性来推测出单词含义，或者根据选项单词的用法来排除。
例三：
Paragraph 3: Population cycles are characteristic of small mammals, and they sometimes appear to be brought about by predators. Ecologists studying hare populations have found that the North American snow shoe hare follows a roughly ten-year cycle. Its numbers fall tenfold to thirty in a typical cycle, and a hundredfold change can occur. Two factors appear to be generating the cycle: food plants and predators.
5. The word “roughly” in the passage is closest in meaning to
O usually
O repeating
O approximately
O observable
解析：正选是C。单词所在句子为“Ecologists studying hare populations have found that the North American snow shoe hare follows a roughly ten-year cycle.”意思是：生态学家对野兔数量的研究发现，北美白靴兔一直遵守着大约以十年为周期的循环。
这个题目仅根据语境来判断，很难得到答案。
根据以上的三个例子可以看出，在托福阅读词汇题的解答过程中，一些题目可以根据上下文之间的关联或者句子逻辑来判断，但是并不是所有的题目都可以依靠语境来解答。这些题目的解答则需要依靠考生的词汇掌握。
以上就是前程百利小编带来的托福阅读词汇题猜词的方法不一定可靠的相关说明。这一类题型的考察目的是语境下的词汇含义，但是为了能够不再这类题目上出错，或者节省答题时间，大家将词汇基础打牢也很重要。预祝大家托福考试取得好成绩!
