托福宝宝最想问的问题：怎么解托福阅读句子转换题的套路

 很多位同学都有一个疑问：为什么总在托福阅读的句子转换题上犯错误、栽跟头。的确，句子转换题是比较难的一类题，但并不是没有方法可循。熟练掌握了方法，它也是一道送分题。今天，小编就跟大家分享句子转换题的解题思路和方法。

句子转换题要求选出一个句子，其句意与原文中指定句的主要意思相同。一般来说，并不是每篇文章都会有此类题目。并且，一篇文章最多只会有一道句子转换题。所有句子转换类的托福题目都是一样的。在原文中，目标句被用阴影标示出来，然后，题目会问到：

“Which of the following best expresses the essential information inthe highlighted sentence? Incorrect answer choices change the meaning inimportant ways or leave out essential information.”

根据题目可以看出，这个题型考查的是考生对句子信息和逻辑关系的把握能力。请看下面这道例题：

There is still no universallyagreed-on explanation for why there should be such a dramatic cessation of treegrowth at the upper timberline. Various environmental factors may play a role.Too much snow, for example, can smother trees, and avalanches and snow creepcan damage or destroy them. Late-lying snow reduces the effective growingseason to the point where seedlings cannot establish themselves. Wind velocity also increases with altitude and maycause serious stress for trees, as is made evident by the deformed shapes athigh altitudes. Some scientists have proposed that the presence ofincreasing levels of ultraviolet light with elevation may play a role, whilebrowsing and grazing animals like the ibex may be another contributing factor.Probably the most important environmental factor is temperature, for if thegrowing season is too short and temperatures are too low, tree shoots and budscannot mature sufficiently to survive the winter months.

Which of thesentences below best express the essential information in the highlightedsentence in the passage? In correct choices change the meaning in importantways or leave out essential information.

A. Because oftheir deformed shapes at high altitudes, trees are not likely to be seriouslyharmed by the strong winds typical of those altitudes.

B. As altitudeincreases, the velocity of winds increase, leading to a serious decrease in thenumber of trees found at high altitudes.

C. The deformedshapes of trees at high altitudes show that wind velocity, which increase withaltitude, can cause serious hardship for trees.

D. Increasedwind velocity at high altitudes deforms the shapes of trees, and this may causeserious stress for trees.

做句子转换题，第一步一定要把握目标句信息，第二就是对比目标句和选项的不同了。那么首先要做的是读懂目标句。理清目标句的信息点数量和逻辑关系以后，再去看选项。在本道例题中，目标句“Wind velocity also increases with altitude and may causeserious stress for trees, as is made evident by the deformed shapes at highaltitudes.” 的信息点有三个：

1. 风速和海拔成正比;

2.风速会对树木造成巨大压力;

3.高海拔处畸形的树木可以证明这一点。

此外，在目标句中还有一层逻辑关系：过快的风速会造成树木变形。带着这样的信息再看四个选项，是不是具备以上重要信息，是不是有那一层逻辑关系。本题中，A选项逻辑混乱，不知所云，完全不符合原文。B选项虽然前半句逻辑关系正确，但是后半句的信息原文中未提及。C选项完整的展现了原句信息，且逻辑关系也符合原句，因此，是正确选项。D选项虽然展现了全部信息，但是因果关系故意混淆视听，属于干扰项。

考生们需要注意的是，句子转换题中，错误选项通常具有以下特点：

1. 信息不完整或不符合原文。

2.信息虽完整但是逻辑关系混乱。在真实的考试中，目标句的信息和逻辑关系可能会比例题更复杂一些。但是，万变不离其宗。
