(2023·陕西中考)Farmyard robots can cut down chemical pollution
1? Many of them use chemicals to kill weeds(杂草). 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.
3?
Several cameras are built into the robot. The cameras facing the ground take photos to help the robot "see" the plants it passes.
The robot compares each photo to a library of plant photos to decide on which plants are weeds.
Robot arms move into position to give a small dose(剂量) of weedkiller on the weeds.
The robot is energy-friendly. 4.
How will the robot develop?
The scientists do not want to just stop at the achievement they have made. 5. The improved model of robots will exactly discover weeds and dig them out instead of using weedkillers.
Robots could be programmed to leave some harmless weeds in the fields to support wildlife living there.
A. But scientists have created a farmyard robot
B. It is powered by the energy from the sun
C. Where is the robot used
D. They're working on the new designs to improve the model
E. How does the robot work
F. Why do farmers choose the robot to work in their fields
G. How do farmers usually kill weeds in the fields

答案
Ⅴ.【文章大意】本文是一篇说明文，介绍了一款新型农用机器人，它可以减少化学除草剂的使用。
1.G 2.A 3.E 4.B 5.D
1.G 2.A 3.E 4.B 5.D
解析
【分析】
1. 信息还原思路：先通读全文，明确文章介绍农用机器人减少化学污染的主题；再逐一分析每个空的上下文逻辑：第1空后讲农民用化学品杀杂草，故前问除草方式，选对应选项；第2空后讲机器人减少除草剂，故前引出科学家创造机器人；第3空后讲机器人工作流程，故前问工作方式；第4空前提机器人节能，故后补充能源来源；第5空前提科学家不满足，故后提改进模型。
【解析】
Ⅴ. 信息还原：
1. 第1空：下文提到“Many of them use chemicals to kill weeds”，说明此处询问农民除草的方式，对应选项G，故选G。
2. 第2空：下文介绍机器人减少除草剂使用，说明此处引出科学家创造了这种机器人，对应选项A，故选A。
3. 第3空：下文详细说明机器人的工作流程，说明此处询问机器人的工作方式，对应选项E，故选E。
4. 第4空：上文提到机器人节能，此处补充其能源来源，对应选项B，故选B。
5. 第5空：上文说科学家不满足现有成就，下文讲改进模型，说明此处指科学家在做新设计，对应选项D，故选D。
【答案】
Ⅴ. 1.G 2.A 3.E 4.B 5.D
英语信息还原、英语语法（时态与语态、固定搭配）
【点评】
本题涵盖中考核心题型，信息还原考查语境逻辑衔接能力，适当形式填空考查基础语法运用，整体难度适中，需学生掌握语境分析和基础语法规则。
【难度系数】
0.6
