A company called Neuralink has shared a video where a monkey is playing a video game. That' s fairly unusual,

but what makes the video even stranger is that the monkey is playing the video game with just his mind.

The monkey in the video is called Pager who has two of Neuralink's special "Link" devices(装置)inside his

brain. The devices planted in Pager's brain are connected to 2,048 wires which lead to the parts of Pager's brain

that control movements of the arms and hands.

Scientists taught Pager to play a video game. At first, Pager controlled the video game using a joystick it,

which is a normal gaming controller. But as Pager played, his Link devices wirelessly sent out information about

the signals his brain was using to control his arms and hands. Neuralink's scientists recorded all of these signals.

Then they used computers to match the signals from Pager's brain to the movements that his hands were

actually doing. This was the most difficult work and the scientists counted on artificial intelligence ( AI) to help

them decode(解码)Pager's brain signals.

The final step was to have a computer make moves inthe video game as if Pager had actually moved the

joystick. If Pager thought about moving the joystick up, the computer would send an “up” signal to the video

game.

At first, the researchers let Pager keep moving the joystick with his hand, even though it was no longer

connected to the computer. But soon Pager was able to play the video game using just his brain.

Even though Neuralink's work right now focuses on animals and video games, there's a very serious purpose behind it. Neuralink wants to make it possible for humans who have lost the ability to make physical movements

to interact with the world around them.

4. What are “Link” devices used to do?

A. To pick up the arms' and hands' signals.

B. To link the computer to the monkey's brain.

C. To send out information about the brain's signals.

D. To control movements of the arms and hands.

It's just before l pm and hungry guests are starting to emerge out onto the wooden floor at the back of the

Victoria Falls Safari Lodge in Zimbabwe. A few have already settled in for lunch, drinking beer and enjoying their

sandwiches and salads in the sunshine. It's a normal setting until you look up. Overhead, the sky is filled with

several hundred vultures (秃鹭).

They too have arrived for their midday snack. Every day the team at this hotel places last night's leftover

meat out for the vultures to eat. They call it the "Vulture Restaurant" and it's a vital part of protecting these birds,

who have become some of the most endangered species in Africa.

In Zimbabwe, where illegal hunting of elephants and rhinos is a major issue, poisoning poses a significant

2019-2020学年长沙长郡中学高三语文期中考试试题及答案解析

一、现代文阅读（36分）

(一)现代文阅读I(9分)

阅读下面的文字，完成下面小题。

材料一：

“前两季的夏粮和早稻已丰收到手，分别比上年增产24.2亿斤、20.6亿斤，夏粮产量创历史新高，秋粮面积预计比上年增加800万亩，丰收在望。”农业农村部相关官员介绍说，2020年还是一个丰收年，粮食会有个好收成。

手中有粮，心中不慌。中国始终高度重视粮食安全，把14亿人的吃饭问题作为头等大事来抓。“十三五”期间，严守18亿亩耕地红线，加大粮食生产政策支持力度，粮食连年丰收，产量持续稳定在1.3万亿斤以上。2019年，中国粮食产量刷新历史纪录，达到13277亿斤，人均粮食占有量超470公斤，持续高亍世界平均水平。“中国用全球9%的耕地和6%的淡水资源满足了占全球近20%人口的粮食需求，这是非常了不起的伟大成就。”联合国粮农组织总干事称赞道。浓浓的科技范儿改变着农业，也增添了发展动力和活力。“十三五”期间，中国持续加强农业与科技融合，中国农作物耕种收综合机械化率超过70%，农业科技进步贡献率达到59.2%，均较2015年显著提高；主要农作物自主选育品种升至95%，稳稳地做到了“中国粮用中国种”。

“十三五”期间，中国不断加强粮食储备应急管理，形成了中央储备和地方储备协同运作、政府储备和企业库存互为补充的粮食库存体系。当前中国粮食库存处于历史高位，特别是稻谷、小麦，这两大口粮的库存可满足全国居民1年的消费需求。

（摘编自邱海峰《1.3万亿斤以上！“中国饭碗”稳稳的》，《人民日报海外版》2020年9月30日）

材料二：

受新冠肺炎疫情冲击、洪涝灾害影响和国际粮价震荡传导，近期我国粮食市场运行出现阶段性波动，这一波动受到了全社会的广泛关注。数据显示，当前我国粮价稳中有涨，品种间走势有所分化，不同环节价格波动有所差异。7月份，稻谷、小麦、玉米三种粮食集贸市场均价为每百斤122.4元，环比上涨0.2%，同比上涨1.7%。其中，稻谷价格涨幅最小，小麦次之，玉米价格涨幅较为明显，收购、批发环节粮价涨幅偏大。
