记叙文 推动数字教育 ★★ 8 min P37
　　As the world has changed，so has education. Since 2018，Nelly Cheboi and her non-profit TechLit Africa have been bringing computer technology into schools in Kenya，helping students join the digital world，and unlock their potential. With its own software programmes，curriculum (课程) and teacher training programmes，this non-profit hopes to change Africa.
In 2012，Cheboi received a scholarship to the College in Illinois that changed her life. She grew up in poverty in rural Kenya，watching her mother struggle to support her family alone. Cheboi had no experience with computers before moving to the US to study. She handwrote papers and then struggled to type them out on a laptop computer. Somehow she fell in love with computer science and began a career in the field. But she did not lose sight of her origins. “As an undergraduate，I invested all of my income from various campus jobs into my community back in Kenya，” she said on the TechLit Africa website. But soon she wanted to do more for it and that is how TechLit Africa began.
Cheboi recalled how her background helped her understand how important technological knowledge could be for children living in poverty. She built a school with the idea of bringing computer science as part of kids’ curriculum growing up. But she found that it was going to be really hard to impact as many people as possible，because it was so hard to raise funds. Then in order to reach more students，she introduced computer training to existing schools. Cheboi physically dragged over 40 recycled computers that had been donated to them by various tech companies to Kenya in suitcases.
Now，since the non-profit has grown，it works with various companies that help them clean the donated computers of data and send them to Africa. TechLit Africa runs its own curriculum with its own software programmes in 10 Kenyan schools，and the hope is to increase to 100 throughout Africa by next year. The students love learning about computers，and in turn are gaining skills that will help them make use of their talents into a way out of poverty.

说明文 AI预测临界点 ★★★ 8 min P38
　　Tipping points，also known as critical transitions (转变)，are mathematical cliff-edges influencing everything in our life. The financial crisis of 2007 to 2009 is often described as one. So is the moment that a terrible pandemic went global in 2020. Anyone can spot a tipping point after it’s been crossed. But it is extremely difficult to spot them before they happen.
Computer scientists in China now show that artificial intelligence (AI) can help. In a recent study，the researchers accurately predicted the beginning of tipping points in complicated systems with the help of machine-learning algorithms (算法). It could help solve real-world problems，such as predicting floods and power failures.
To simplify their calculations，the team reduced all such problems to ones taking place within a large network of interacting nodes (节点)，the individual elements within a large system. In a financial system，for example，a node might represent a company. The team then designed two artificial neural (神经的) networks to analyse such systems.
To train their model，the researchers firstly turned to simplified theoretical systems in which tipping points are known to occur. Once the model could predict these transitions，it was applied to the real-world problem of how tropical forests turn to savannah (稀树草原). This has happened many times on Earth，but the details remain mysterious. The researchers first analysed the data from three central African regions in the past 20 years and identified the tipping points. They then wanted to see if training their algorithm on data from two of these regions could enable it to correctly predict a transition point in the third. It could.
The team then asked the algorithm to identify the conditions that drove the shift. The answer was，as expected，down to annual rainfall. But the AI was able to go further. The AI detailed that a slight decrease in rainfall from 1，800 mm to 1，630 mm led to a minor 5% drop in tree cover，but a further decrease to 1，620 mm caused a significant 30% drop. This would be a textbook critical transition. And by predicting it from the raw data，the researchers say they have broken new ground in this field.
The team are now trying to discover what specific features the AI identifies to make these predictions，which could help better predict everything from infectious outbreaks to the next stock market crash.
语篇解读：本文是一篇说明文。文章主要介绍了中国计算机科学家如何利用人工智能技术来预测复杂系统中的临界点，这些临界点对我们的生活有着重大影响。
(　　)5.How did the team simplify the calculations
A.By limiting the problems within a large network.
B.By focusing on the individual elements in a network.
C.By transforming the problems into ones in a network.
D.By reducing the number of problems in each network.
【解析】 细节理解题。根据第三段中的“To simplify their calculations，the team reduced all such problems to ones taking place within a large network of interacting nodes (节点)，the individual elements within a large system.”可知，研究小组通过将问题转化为网络中的问题来简化计算。
C
(　　)6.Why was the algorithm trained on data from two central African regions
A.To improve its ability of prediction.
B.To check its analysis of the data.
C.To perfect its solutions to problems.
D.To test the accuracy of its prediction.
【解析】 推理判断题。根据第四段中的“The researchers first analysed the data from three central African regions…They then wanted to see if training their algorithm on data from two of these regions could enable it to correctly predict a transition point in the third. It could.”可推知，算法要在两个中非地区的数据上进行训练是为了测试它预测的准确性。
D
(　　)7.What breakthrough did the AI make in the study
A.It revealed the idea that tipping points are predictable.
B.It identified a critical transition point in the tree cover.
C.It confirmed previous theories about rainfall and tree cover.
D.It predicted the future expansion of savannahs in central Africa.
【解析】 细节理解题。根据第五段中的“The AI detailed that a slight decrease in rainfall from 1，800 mm to 1，630 mm led to a minor 5% drop in tree cover，but a further decrease to 1，620 mm caused a significant 30% drop. This would be a textbook critical transition”可知，人工智能在研究中取得的突破是确定了树木覆盖的一个关键转折点。
B
(　　)8.Which of the following could be the best title for the passage
A.The Analysis of Rainfall： AI and Tree Cover
B.Spotting Tipping Points： A Big Challenge for AI
C.Machine Learning： Predicting Critical Moment
D.Critical Transitions： The Key to Making Predictions
【解析】 标题归纳题。通读全文可知，本文主要介绍了中国计算机科学家如何利用人工智能技术(AI)来预测复杂系统中的临界点(或称为关键转折点)，这些临界点对我们的生活有着重大影响。因此C项“Machine Learning： Predicting Critical Moment”适合作为本文标题。

说明文 虚拟互动设备 ★★★ 8 min P38
　　Feeling a hug from each other via the Internet may be a possibility in the near future. A research team led by City University of Hong Kong recently developed a wireless，soft e-skin that can both detect and deliver the sense of touch，and form a touch network allowing one-to-multiuser interaction. It offers great potential for improving the distance touch communication.
While there are numerous devices in the market to simulate (模拟) the sense of touch in the virtual world，they provide only touch sensing or touch response. The uniqueness of the novel e-skin is that it can perform self-sensing and touch-reproducing functions on the same interface.
The e-skin is a 7 cm×10 cm，4.2 mm-thick device containing 16 flexible actuators (驱动器)，a microcontroller unit，a Bluetooth module，and other electronics on a flexible circuit board. The actuator serves as the core part of the e-skin. Once the actuator is pressed and released by a force，a current is produced to provide electrical signals that are turned into digital signals by a converter (转换器) and then sent to another e-skin via Bluetooth. When the signals are received，a current is caused to reproduce the touch response on the receiver’s e-skin through mechanical vibration (振动). The process can be reversed to deliver vibrations from the receiver’s e-skin to the corresponding actuator of the sender’s.
The e-skin can communicate with Bluetooth devices and send data through the Internet with smartphones and computers to perform long-distance touch，and to form a touch Internet of Things (IoT) system，where one-to-one and one-to-multiple touch delivery could be realised. Friends and family in different places could use it to “feel” each other. This form of touch overcomes the limitations of space and greatly reduces the sense of distance in human communication.
Next，the research team will focus on practical applications for people with visual disability，who could wear the e-skin to gain remote directional guidance and read Braille messages.

说明文 设计网站的建议 ★★ 7 min P38
　　The Internet is a great place to sell your products. 　13　 But it’s not easy to stand out in front of the competition online. To change this，you first must understand that the website is your digital store. In this article，experts from Alpha Efficiency will give us some tips you should follow when designing a website to increase sales.
Use landing pages.
Unique landing pages are vital for increasing sales. These are the pages of your website people first see after clicking on an ad or searching for a product on Google. The purpose of a landing page is to guide visitors’ attention to a specific call to action—in this case，buying your product. You could go even further by creating different landing pages for smaller audience groups. 　14　
　15　
People often use smartphones and tablets to casually browse online stores in the hope of finding an interesting product to buy. And they won’t even check offers on a website that doesn’t provide great user experience. You can improve the website for smartphones and tablets by utilising either adaptive or responsive web design. 　16　
Make it interactive.
There are not many better ways to provide a great user experience than creating a well-designed，interactive website. Do not be afraid to put visitors in control and let them play with the elements of your website. 　17　 Design an innovative way for visitors to check different product colors，sizes，combinations，etc. Interactivity does not only help customers decide which product to pick，but it also improves the chances that they will come back for more fun.
