解析
D1 1-4 CBDC
1. C。联系下文“Around 135 million people had been facing food shortages before the coronavirus outbreak, but now 130 million more could go hungry in 2020 … Altogether, 265 million people are being pushed to the brink of starvation by the COVID-19 crisis”可推知,“on the brink of”的意思是“在……的边缘”,故选C。
2. B。文章第3-5段主要讲了许多世界上许多国家面临的饥饿问题。第3段讲了遭受饥饿的人数由于新冠肺炎的暴发增加了很多;第4段举例说明印度、哥伦比亚的粮食短缺问题;第5段讲了引用了肯尼亚居民说的话,说明了疫情导致失业,从而没有钱买食物。故选B。
3. D。根据Johan Swinnen所说的话“There is no shortage of food globally – yet. But problems in planting, harvesting and transporting food will leave [less developed] countries [facing even more difficult times] in the coming months, especially those reliant (依赖的) on imports”可知,粮食短缺问题目前不是全球性的问题,但是那些依靠粮食进口的不发达的国家可能在未来的几个月内遭遇食物危机,故选D。
4. C。根据最后两段讲述的中国目前的粮食情况( “there’s no need for stockpiling food”,“and the prices remain stable”,“We have the confidence and determination to keep our rice bowls full”)可知,答案选C。
D2 1-4 BCDA
1. B。联系上下文可知,本文讲了500米口径球面射电望远镜与4月28日正式开启地外文明搜索,“embarked on”的意思是“开始”,故选B。
2. C。根据下文“... has influenced minds so deeply that people are worried about the possibility of the Earth being invaded by an advanced extraterrestrial civilization”可知,“Do not answer!”表明了人们担心外星人入侵地球,故选C。在刘慈欣的《三体》中,“不要回答!不要回答!不要回答!”这是来自三体世界监听员对地球人的“警告”。书中曾讲过宇宙是一座黑暗森林,每个文明都是带枪的猎人,他人是永恒的威胁,当外星人发现宇宙中有人类出现的时候,为了保证自己不被我们先毁灭必须要想尽办法毁灭我们。所以,不暴露地球的位置至关重要。
3. D。根据第5-6段中“… less than 20 are capable of supporting life, and the nearest among them, Gliese 581, is 20.4 light-years away”,“there is less than a one in a million chance of any extraterrestrial life form evolving (进化) into higher intelligence or a civilization”可知,这两段主要讲了外星人存在的可能性很小,故选D。
4. A。最后两段主要讲了中国“天眼”的意义,如“… it can best distinguish between manmade and ET-made signals. Even the signals from a non-ET civilization are useful, because they might contain some hidden information leading to the discovery of new stars or planets”,“With FAST joining the cause, mankind can browse (搜索) the universe more deeply than ever before and increase knowledge about the universe”,故选A。
D3 1-3 DAB
1. D。根据文中“Different geological structures and different age periods of the moon are marked with different colors”可知,地图上的不同颜色标记出的是不同的地质结构和年代。
2. A。文章第三、四两段叙述了科学家们为制作这张新地图而付出的努力,如要将之前的纸质地图和不太清晰的地图和新近得到的图像进行比对,而且还要保证将来自不同探月团体的原有地图在统一度量单位之后无缝地拼接到一起。
3. B。由文章倒数第二段中“the new map will serve as a blueprint of the moon’s surface ge-
ology for future human missions”和“This would be especially beneficial as NASA is planning to land astronauts on the moon by 2024... ”可知,这张新地图将在人类未来的探月项目中起到重要的作用。
D4 1-3 DBC
1.D。第二、三段主要讲述了作者早上醒来之后以及日落时分在动物园与动物互动的日常,所以答案选D。

3. C。整篇文章讲述了作者在动物园与动物们相处的日常生活,处处都体现了作者对这份工作的热爱,所以作者写这篇文章的目的是为了与读者分享对这份工作的喜爱之情,故答案为C。
