托福閱讀插入題是公認比較有難度的閱讀題型之一，得分率一直都是比較低的。想要做好這類題目，考生需要了解其考點和解題思路，下面小編就來具體分析。

托福閱讀插入題到底考什么?

做題之前，我們先一起了解下，托福閱讀題的出題意圖是什么：

1、考查是否理解文章內部邏輯關系。

一般考查段落內部-句子之間的邏輯關系，有時也會考查段落之間的邏輯關系。

2、考查是否知道段落間重要的指示詞和連詞的作用。

只有了解起著文章銜接作用的連詞的用法，才能緊隨文章邏輯。

托福閱讀插入題解題思路實操演練

例：

Look at the four squares ■that indicate where the following sentence could be added to the passage.

In either case, the heated water will usually be under considerable pressure, and so may have a temperature that is well above its sea-level boiling point of 100 centigrade.

Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes. It can also be harnessed to drive electric generators and heat homes. Geothermal energy becomes available in a practical form when underground heat is transferred by water that is heated as it passes through a subsurface region of hot rocks (a heat reservoir) that may be hundreds or thousands of feet deep. ■【A】The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. ■【B】The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.■【C】?By far the most abundant form of geothermal energy occurs at the relatively low temperatures of 80° to 180° centigrade. ■【D】Water circulated through heat reservoirs in this temperature range is able to extract enough heat to warm residential, commercial, and industrial spaces.More than 20,000 apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin. Iceland sits on a volcanic structure known as the Mid-Atlantic Ridge. Reykjavik, the capital of Iceland, is entirely heated by geothermal energy derived from volcanic heat.

做句子插入題主要依賴的是語言線索，所以

第一步：仔細閱讀待插入的句子，弄清含義，找出其中包含的銜接手段，預測可能存在的語境。也就是：In either case, the heated water will usually be under considerable pressure, and so may have a temperature that is well above its sea-level boiling point of 100 centigrade.

句子中出現“either case”, either表示兩者中“或者，任一”，意味著原文必提及兩種“case”;

第二步：讀原文，找線索

■ The water is usually occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. ■ The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.■ By far the most abundant form of geothermal energy occurs at the relative low temperature of 80 to 180℃entigrade.■

我們發現原文首句提及“The water is usually occurring groundwater that seeps down along fractures in the rock;”一種情況外，還提到了“less typically, the water is artificially introduced by being pumped down from the surface”這種情況，滿足了“兩種case”的猜測。

于是，我們把待插入句放到第二個小黑框前，檢查一遍，邏輯通順。

這道題中我們的解題突破口是一個叫“either”的詞，除它以外，還有哪些詞可能有邏輯銜接擔當呢?

常見銜接手段：

1.語法銜接手段

語法銜接手段主要指代詞，包括指示代詞和人稱代詞。

指示代詞：this, these, it, such, another, that, these, those

b. 人稱代詞：he, she, one, they, his, her, one’s, their

c. 定冠詞：the

d. such, either, same等

說明插入句的內容上文有提到。

2. 邏輯銜接手段：

a. 因果: because, therefore, thus, consequently, so, as a result

b. 對比: however, on the contrary, nevertheless, unlike, in contrast, while, although, but

c. 遞進: furthermore, also, as well, too, other, in addition, moreover, besides, even, additionally
