逐一分析选项:
A选项:"What are you doing these days?"意为“你最近这些天在做什么?”,答语通常回答具体做的事情,不符合;
B选项:"How are you doing these days?"意为“你最近这些天过得怎么样?”,答语常用"Not bad"等回应近况,符合语境;
C选项:"What are you thinking about these days?"意为“你最近这些天在想什么?”,答语通常回答思考的内容,不符合;
D选项:"What's the weather like?"意为“天气怎么样?”,答语应描述天气,不符合。
因此选B。

六、阅读理解。
主题群:灾害防范 子主题:科技与自然 语篇类型:说明文 难度:★★★
According to a recent study, the Middle East is warming almost twice as fast as the rest of the world. Without doubt, high temperatures will have deep effects on the development of the area.
That shows the growing risk to humans caused by extreme(极端的) weather. With more and more extreme weather events, we must find better techniques to make predictions(预测) about them.
AI is a powerful tool. It can deal with information and provide advice to help us better understand and make predictions about the weather. Traditional weather models use information from satellites. But these models have their disadvantages: they are not very exact. They also fail to discover complex(复杂的) conditions of the air around the earth.
AI can overcome(克服) these disadvantages by using the technology of deep learning. It can learn from historical and real-time information and produce trustworthy predictions. AI can also deal with information from different places, such as satellite photos or online posts, to provide clearer pictures of the weather situation. A paper on the Pangu-Weather AI model has drawn a lot of attention. Pangu-Weather is the first AI prediction model that is more exact than traditional weather prediction methods. This model can increase the prediction speed by 10,000 times, making global weather prediction time drop to seconds.
In May 2023, Typhoon Mawar appeared in the Pacific Ocean. According to China Meteorological Administration, Pangu-Weather made exact predictions about the direction of Mawar five days before it changed its way in the eastern waters of Taiwan, China.
1. Which of the following is true?
A. High temperatures will have few influences on the area.
B. The Middle East is warming faster than the rest of the world.
C. Traditional weather models can discover complex conditions of the air around the earth.
D. Traditional weather models use information from satellites and are very exact.
2. How can AI overcome the disadvantages of traditional weather models?
A. By using information from satellites.
B. By only learning from real-time information.
C. By using the technology of deep learning.
D. By dealing with information from the same place.
3. Why is Typhoon Mawar mentioned?
A. To show how exact Pangu-Weather's predictions are.
B. To tell us about the risks of extreme weather.
C. To talk about how useless traditional weather models are.
D. To show that the problems of extreme weather have been solved completely.
4. What might be the best title for the text?
A. The Risks of Extreme Weather
B. The Pangu-Weather AI Model
C. The Climate Change in the Middle East
D. AI—the Powerful Tool of Weather Prediction

答案

1. B 2. C
3. A 推理判断题。第五段提到台风玛娃的例子,是为了佐证前文“Pangu-Weather is the first AI prediction model that is more exact than traditional weather prediction methods.”,即证明该AI模型预测的准确性。
4. D 标题归纳题。全文围绕“AI在天气预报中的应用”展开,先提出极端天气需要更精准的预测手段,再介绍AI如何克服传统模型的缺点,最后用实例证明AI预测的优势。
方法归纳
阅读理解之标题归纳题
解题时要抓住文章主旨,重点关注首段、尾段及各段主题句。所选标题需覆盖全文内容、体现中心思想,同时简洁醒目。排除只涉及细节、范围过大或偏离主题的选项。

解析

【分析】
做这几道阅读理解题时,需先通读原文把握主旨,再带着每个题目选项回到原文定位对应信息,逐一比对分析排除错误选项:第1题需定位关于中东变暖、高温影响、传统天气模型的内容;第2题定位AI克服传统模型缺点的方式;第3题定位台风玛娃例子的作用;第4题需梳理全文核心内容,归纳主旨确定标题。
【解析】
1. 细节理解题:根据原文第一段“the Middle East is warming almost twice as fast as the rest of the world”可知B选项正确;A选项与原文“high temperatures will have deep effects on the development of the area”不符;C选项与原文“they are not very exact. They also fail to discover complex conditions of the air around the earth”不符;D选项与原文“they are not very exact”不符,故选B。
2. 细节理解题:根据原文第四段“AI can overcome these disadvantages by using the technology of deep learning”可知C选项正确;A选项是传统模型的信息来源,不是AI克服缺点的方式;B选项与原文“learn from historical and real-time information”不符;D选项与原文“deal with information from different places”不符,故选C。
3. 推理判断题:第五段提到台风玛娃的例子,是为了佐证前文“Pangu-Weather is the first AI prediction model that is more exact than traditional weather prediction methods”,即证明该AI模型预测的准确性,故选A。
4. 标题归纳题:全文围绕“AI在天气预报中的应用”展开,先提出极端天气需要更精准的预测手段,再介绍AI如何克服传统模型的缺点,最后用实例证明AI预测的优势,D选项覆盖全文主旨;A选项仅涉及极端天气风险,B选项仅为文中例子,C选项仅涉及中东气候变化,均未体现核心,故选D。
【答案】
