对于托福阅读的指代题，不知道同学们有没有了解过呢？指代题在同学们心中的印象可能没有那么深，但是也是非常重要的一种题型，那么接下来就和出国留学网来了解一下如何做托福阅读中的指代题？
指代题题量不多，在不加试的情况下，三篇文章可能只会考到一道指代题。而且在TPO1-53的所有题目中，指代题一共考察过23道。这可能会给大部分同学一种错觉，指代似乎并不是那么重要。但也就是这么一个小小的指代，会影响到我们做其他题型的正确率以及速度。

[TPO34-] Protection of Plants by Insects
Paragraph 5： … Observations leave little doubt that ants protect morning glory flowers and fruits from the combined enemy force of grasshoppers， caterpillars， and seed beetles. Bentley compares the seed production of six plants that grew where there were no ants with that of seventeen plants that were occupied by ants. Unprotected plants bore only 45 seeds per plant， but plants occupied by ants bore 211 seeds per plant. Although ants are not big enough to kill or seriously injure grasshoppers， they drive them away by nipping at their feet. Seed beetles are more vulnerable because they are much smaller than grasshoppers. The ants prey on the adult beetles， disturb females as they lay their eggs on developing fruits， and eat many of the eggs they do manage to lay.
According to paragraph 5， ants defend morning glory plants from seed beetles in each of the following ways EXCEPT
A） driving adult beetles off the plants by nipping at their feet
B） catching and eating adult beetles
C） ating beetle eggs they find on developing fruits
D） making it difficult for beetles to lay eggs on developing fruits
