官方真题Official34-3 Protection of Plants by Insects【Paragraph 5】Extrafloralnectaries at the base of each sepal attract several kinds of insects, but 96 percent of them are ants, several different species of them. When buds are still small, less than aquarter of an inch long, the sepal nectaries are already present and producing nectar. They continue to do so as the flowerdevelops and while the fruit matures. 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 byants 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 laytheir eggs on developing fruits, and eat many of the eggs they do manage to lay.12. According to paragraph 5, antsdefend morning glory plants from seed beetles in each of the following waysEXCEPTA. driving adult beetles off the plants by nipping at their feetB. catching and eating adult beetlesC. eating beetle eggs they find on developing fruitsD. making it difficult for beetles to lay eggs on developing fruitsEXCEPT选非过程：1. 审题：找到题干核心词seed beetles2. 定位：确定出题区间，找到列举信息Although ants are not big enough to kill or seriously injure grasshoppers, they drivethem 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.3. 排除：排除符合原文要求的三个选项，注意选项的同义改写B. catching and eating adult beetles抓捕和吃掉成年甲壳虫= the ants prey onthe adult beetles 蚂蚁捕食成年甲壳虫C. eating beetle eggs they find on developing fruits吃掉在水果上的甲壳虫卵= eat many of the eggs they do manage to lay 蚂蚁吃掉甲壳虫成功产下的卵D. making it difficult for beetles to lay eggs on developing fruits 使甲壳虫很难再发育的水果上产卵= disturb females as they lay their eggs on developing fruits 蚂蚁干扰正在水果上产卵的雌性甲壳虫有同学说，A选项nipping at their feet(夹它们的脚)也对应了原文they drive them away by nipping at their feet，那我们来看看nipping at their feet这句话原句具体信息：Although ants are not big enough to kill or seriously injure grasshoppers,they drive them away by nipping at their feet.尽管蚂蚁还不足以大到能够杀死或严重伤害蚂蚱，但是蚂蚁可以通过夹它们的脚赶走蚂蚱。

所以，本题最后的答案是：ATIPS:1. 符合题干要求的三个选项一般以列举形式出现，比如a, b, and c;或者first，second 、moreover / furthermore, third / final等。

2. 当四个选项都在原文当中出现时，必定有一个答非所问，请注意看清题干要求官方真题Official20-1 Westward Migration【Paragraph 2】Why were these hundreds of thousands of settlers—most of them farmers, some of them artisans—drawn away from the cleared fields and established cities and villages of the East? Certain characteristics of American society help to explain this remarkable migration. The European ancestors of someAmericans had for centuries lived rooted to the same village or piece of land until some religious, political, or economic crisis uprooted them and drove them across the Atlantic. Many of those who experienced this sharp break there after lacked the ties that had bound them and their ancestors to a single place. Moreover, European society was relatively stratified; occupation and social status were inherited. In American society, however, the class structure was less rigid; some people changed occupations easily and believed it was their duty to improve their social and economic position. As a result, many Americans were an inveterately restless, rootless, and ambitious people. Therefore, these social traits helped to produce the nomadic and daring settlers who kept pushing westward beyond the fringes of settlement. In addition, there were other immigrants who migrated west in search of newhomes,material success, and better lives.4. According to paragraph 2, all of the following are reasons why Americans migrated westward EXCEPTA. the desire to move from one place to the nextB. the hope of improving their socioeconomic statusC. the opportunity to change jobsD. the need to escape religious or political crises点评：本题是一道非常经典的选非题，很多同学在做本题时都会很快的排除D选项，因为D：the need to escapereligious or political crises实在太容易在原文当中找到对应的句子：The European ancestors of some Americans had for centuries lived rooted to the same village or piece ofland until some religious, political, or economic crisis uprooted them and drove them across the Atlantic.所以，很多同学在排除D选项之后，好得意哟!但，D选项就是咱们的正确答案!What!!!下面，我们来看一下解题过程。
