训练2： （陕西中考)1. G. How do farmers usually kill weeds(杂草) in the fields? Many of them use chemicals to kill weeds. The trouble is, these weedkillers also kill wildlife, pollute rivers and are bad for the fields. 2. . This kind of robot can cut weedkiller use by 90%. The robot is really smart because it only kills weeds but not crops(庄稼).
A. But scientists have created a farmyard robot
B. It is powered by the energy from the sun
C. Where the robot is used
D. They're working on the new designs to improve the model
E. How the robot works
F. Why do farmers choose the robot to work in their fields

训练 2 A 【解析】根据下文“This kind of robot can cut weedkiller use by 90%.”可知，这种机器人可以减少90%的除草剂使用量，此处提到一种机器人；A项“但是科学家们创造了一种农场机器人”符合语境，与上文提到的农民用化学药品除草造成的危害形成对比。

【分析】本题为英语语篇句子还原题，需结合上下文逻辑关系解题。上文介绍农民用化学除草剂除草的危害，下文提到指代机器人的“this kind of robot”，因此空格处应引出“机器人”相关内容，起到承上启下的作用。
【解析】根据上下文逻辑，上文说明传统除草方式的弊端，下文出现指代机器人的表述，空格处需引出“机器人”的相关内容。A项“但是科学家们创造了一种农场机器人”既承接上文化学除草的问题，又引出下文的机器人，符合语境；其余选项（B项讲动力、C项讲使用地点、D项讲改进设计、E项讲工作方式、F项讲选择原因）均不符合此处承上启下的逻辑。
【答案】A
【知识点】英语句子还原、语篇逻辑衔接
【点评】本题考查英语语篇的上下文衔接能力，难度适中，只需理清前后文的指代关系和逻辑联系即可快速选出正确答案，是中考英语常见的基础题型。
