They baby is just one day old and has not yet left hospital. She is quiet but alert (警觉)。Twenty centimeters from her face rearchers have placed a white card with two black spots on it. She stares at it carefully. A rearcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lo its focus - until a third, with three black spots, is prented. Her gaze returns；she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects(a comb, a key,an orange and so on),changing the number of objects had an effect parate from changing the objects themlves. Could it be the pattern that two things make, as oppod to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed fro
m two to three, or three to two. The effect even cross between ns. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewi(同样地) when the rearchers started with drumbeats and moved to spots.

A
There was a lot of news related to artificial intelligence, or AI, and machine learning. Among the stories were two dealing with direct competitions between humans and machines.
In one competition, machines that ud AI performed better than human beings in a high-level reading test. Two natural language processing tools beat human in the experiment. One of the tools was built by the American technology company Microsoft. The other was created by Chine online ller Alibaba Group.
In another competition, a computer took on humans in live, public debates. The event demonstrated how AI-powered computers are increasingly being developed to think and sound like humans. The organizer of the debates, U. S. technology company IBM, announced split results. It said a majority of tho watching said they felt the machine had done more to improve their knowledge of the subject. But, the human got more prai for communicating their ideas.
This year, we also explored the many ways AI and machine learning are now being ud. For example, some U. S. judges u machine learning systems to help them decide when, and for how long, criminals
should be jailed. The system us computers to examine data from thousands of court cas.垃圾收集点
One fast-growing area of AI is facial recognition, which is increasingly being ud for curity purpos. Recently, Atlanta's Hartsfield-Jackson airport became the first in the U. s. to permit pasngers to u facial recognition technology to get on flights. A Chine company showed off an AI system it developed to recognize individuals by body shape and walking movements. The system is already being ud by Chine police in Beijing and Shanghai.
九言In addition, machine learning was ud during 2018 to predict results of the World Cup soccer competition. The technology also created artwork that sold for a large amount of money. And it is being ud to help farmer save time and money, while reducing environment-harming chemicals. Other technology systems are being ud to follow farm animals and wildlife to collect information on their activities.
1. Why were the two competitions mentioned in the passage?
A. To show how much better AI and machine learning are than humans.
B. To prove AI and machine Learning got more prai for communication.
C. To show how powerful AI and machine Learning are.
D. To prove AI and machine learning have been ud in the work of U. S. judges.
2. What are facial and body recognition systems ud for in the passage?
A. Knowledge learning.
B. Safety control.
C. Office automation.
D. Tracking survey.
3. What can we infer from this passage?
A. AI has been widely ud in every person's daily life.
B. Human can be replaced by AI in future completely.
C. More attention is being paid to AI in every part of the world.
D. More advanced Al is helping people in more and more areas.
见利思义4. Where is the text probably from?
A. A technology report.
B. A natural science magazine.
C. science fiction.
D. A government document.

美国间谍Many of us love July becau it’s the month when nature’s berries and stone fruits are in abundance. The colou rful and sweet jewels form British Columbia’s fields are lit tle powerhous of nutritional protection.
Of the common berries, strawberries are highest in vitamin C, although, becau of their eds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.
A：【解析】这是一篇说明文。人工智能和机器学习快速发展，机器在一些比赛中超过了人类。除此以外，机器和人工智能被应用于很多领域。
p档是什么档
1.推理判断题。根据第二第三段可知在第一场比赛中，使用人工智能的机器表现得比人类更好；在第二个比赛中，机器人在公开辩论中挑战人类，结果大多数观看者认为机器在提高他们对这门学科的知识方面做得更好。这两个比赛都体现了人工智能和机器学习的强大，选C。
电讯报2.细节理解题。根据“One fast-growing area of AI is facial recognition, which is increasingly being ud for curity purpos.”可知人工智能的一个快速发展的领域是面部识别，它越来越多地被用于安全目的。故选B。
3.推理判断题。根据“some U. S. judges u machine learning systems to help them decide when,”可知一些美国法官使用机器学习系统来帮助他们决定罪犯应该被监禁的时间和期限，再根据最后两段可知机器学习和人工智能还被应用于安全监控和预测世界杯足球赛的结果，保护环境等。根据这些可以推断机器在越来越多的领域帮助着人类，故选D。
4.推理判断题。本文文章主要是关于人工智能和机器学习的，最有可能是来自于科技报告（A technology report.），故选A。
B：【解析】本文是一篇日常生活类说明文。文中讲述了人们热爱水果丰盛的7月，这时候各种水果营养丰富且含有对人体有益的微量元素，尤其是香蕉。我们可以利用它做一些孩子喜欢的甜点或冰淇淋。
5.细节理解题。题干问的是，作者喜欢樱桃什么。根据第二段中As for cherries (樱桃), they are so delicious who cares?（至于樱桃，因为它们很好吃谁在乎呢?）可知，作者在乎的是它的美味。故选C。
6.细节理解题。根据第三段中的If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown.可知，往香蕉上滴新鲜的柠檬汁是为了防止香蕉变成褐色，故新鲜的柠檬汁是被用来保持香蕉的颜色的。故选B。
7.词义猜测题。根据最后一段中they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below可知，孩子们喜欢把一些水果和冷冻的香蕉放入到这台机器的上部，然后看到冰激凌从下面出来。故可以推出a juicer就是一台机器。故选D。8.文章出处题。文章首先指出七月是水果盛产的季节，并指出各种水果富含的营养，最后一段指出我们可以用a juicer为孩子们做一些甜点和冰激凌，故最可能是从健康杂志上摘取的文章。A项意为：生物教科书；B项意为：一本健康杂志；C项意为：一篇研究论文；D项意为：一本旅游手册。故选B。
