Chokwe Selassie, an eighth-grader at Blackburn Middle School, was inspired to create an app on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole (坑洞) in the middle of the street in their hometown of Jackson, Mississippi. “I wanted to do something about the pothole problem in my city,” Chokwe, 13, told TFK.

Chokwe developed the app with his friends Rodriguez Ratliff and Emmanuel Brooks. “When the app detects a pothole, it is highlighted in red,” Chokwe says. “And if you get close to the pothole, your phone will warn you with a beep sound.” Drivers can also use the app to report any potholes they come across, and to look for other routes they can take to avoid roads that have them.

The app relies on current available information about the streets of Jackson, according to Chokwe. “It works by using the city’s 311 call system, so it uses information already stored in a database,” he says. Through the call system, citizens dial 311 to report non-emergency problems — which include potholes.

To get some help in developing the app, the boys took part in a Minority Male Makers Program sponsored by Verizon (an American broadband and telecommunications company) and held at Jackson State University. The program provides nearly 1,000 American middle school boys across the country with training in advanced technology.

“The students were really excited to participate and learn new things,” says Valerie Bradley, Chokwe’s principal at Blackburn Middle School. Through the program, Chokwe says, he and his friends received encouragement and guidance.

Although the app isn’t yet available for sale, Chokwe is already looking for ways to improve it. The prototype (雏形) remains limited to 10 streets in Jackson, but he hopes to add more, so that it includes every street in the city. And then he wants to go even farther. “I want to keep working on the app until it’s nationwide,” Chokwe says.

1. What is the app designed by Chokwe aimed at?
A.Perfecting the city’s 311 call system.
B.Planning the best routes for drivers.
C.Measuring the streets in Jackson.
D.Helping drivers avoid potholes.
2. What does the second paragraph mainly explain?
A.How Chokwe’s app works.
B.What Chokwe’s app relies on.
C.Where Chokwe’s app can be used.
D.Whom Chokwe’s app is designed for.
3. Whom is Verizon’s Minority Male Makers Program popular with?
A.Students at Jackson State University.
B.Teachers at Blackburn Middle School.
C.Boys who are interested in technology.
D.Males like driving and repairing vehicles.
4. Which of the following words can best describe Chokwe?
A.Proud.B.Honest.
C.Ambitious.D.Independent.

文章大意:这是一篇说明文。文章主要介绍目前的电动汽车虽不直接使用化石燃料,但仍然不是环保的。如果电动汽车有太阳能电池板可以充电,这样的汽车才能实现真正的环保。但是目前使用的太阳能电池板的性能仍受诸多因素限制。

【推荐1】In recent times, with the coming of electric cars, the idea to fuel them with solar energy gained momentum (势头). Electric cars — even though they run on electricity and don’t use fossil fuels — are still NOT GREEN! People suffer from the misconception that not using fossil fuels means “green” which is kind of absurd, considering the electricity we use is produced by burning the very same fuels!

However, what if your car had solar panels that could charge it? Now that would indeed be a green machine! Though we would like to incorporate (使并入) this energy source into our car, the efficiency of the currently used solar panels is subject to the fulfillment of different criteria.

Firstly, solar panels take up a large amount of area. An average car has an area of 10-25 square feet on the roof, which can produce between 50-150W under ideal conditions. This is hardly enough power to make a light bulb function normally! Also, the moderate sunny temperature is ideal, as extremely high temperatures can reduce the efficiency of the solar panels. Cars must work in all weather conditions, so if a solar panel limits the car’s function, it will become practically useless. More importantly, the cost of the panels and development required to power the electronics using the sun’s energy outweighs the benefits that solar panels provide.

Most cars today that have solar roofs use solar energy to power only a few basic functions of the car. While there is still time before we will be able to drive cars fully powered by solar energy, there are some alternatives (可供选择的事物), such as solar power stations, which are being designed to reduce our reliance on fossil fuels for electricity.

Solar-powered vehicles are surely the future, but not the near future. As the cost of solar panels continues to fall and their efficiency increases, things will begin to look much “brighter” for this alternative and sustainable option!

1. Why aren’t electric cars environmentally friendly?
A.They are not powered by solar energy.B.They cause more pollution to the world.
C.They won’t work as well as the common cars.D.They run on electricity produced by burning fuels.
2. What can we learn from the third paragraph?
A.Powering the electronics costs little.
B.Temperatures have little effect on solar panels.
C.A car’s roof generates enough power to light a bulb.
D.The performance of current solar panels depends on various factors.
3. What can we know about fully solar-powered cars?
A.They have already been in use.
B.They will be available in the near future.
C.They will be powered from solar-power stations soon.
D.They can use solar energy to power all functions of the car at present.
4. Which of the following can be the best title for the passage?
A.What do solar cars look like?B.How do solar cars work?
C.Could solar cars replace the electric cars?D.Why don’t we power the car with solar energy?

【推荐2】Want to get your package delivered via robots? Now there’s an app for that. If you live in Washington D. C. , or Redwood, you may have glimpsed a small, boxy robot rolling along a local sidewalk, minding its own business, but attracting the attention of many curious onlookers.

The autonomous machines were part of a pilot program last year by Starship Technologies focusing on delivering meals from local restaurants in dozens of cities around the world. This week, the company unveiled plans to broaden its delivery service beyond food to include package, a move that led it to declare itself “the world’s first robot package delivery service”. The next time you order food, this cute robot might roll up to deliver it. The package delivery service is not available to everyone yet.

The wheeled robots have a top speed of 4mph and can detect obstacles from 30 feet away. “The robot can operate through anything,” Nick Handrick, head of operations for Starship’s D.C. office, said. “ If you had something in the way — a stick — it’s able to climb sticks.”

To sign up for the service, which costs a little more than $ 10 per month, customers need to download the company’s app. Customers then create a “Starship Delivery Address”, a unique address inside a Starship facility, where they can have package sent from places such as Amazon.com. Once a package is delivered to the Starship address, customers receive a text notification that allows them to schedule a home delivery via robot. The robots are opened by customers via a mobile phone code.

Barriers exist for robotic ground delivery, with many states requiring that humans be in control of delivery robots. Those regulations haven’t stopped Starship Technologies from accumulating experience on streets around the globe ahead of the company’s latest launch. The company says its robots have covered more than 125,000 miles in more than 100 cities in 20 countries.

1. What can we know about the robotic delivery?
A.It is part of a trial project by Starship Technologies.
B.You can use the service free of charge via smart phones.
C.The robots are opened by customers with a text notification.
D.The robotic delivery is available to everyone at present.
2. What does the underlined word “unveiled” in paragraph 2 probably mean?
A.RevisedB.Released
C.RestoredD.Reset
3. What is the last paragraph mainly about?
A.The good news of the service.
B.The disadvantages of the robotic delivery.
C.How the robotic delivery works.
D.Robotic delivery develops despite challenges.
4. What is the best title for the text?
A.A New Robot Was InventedB.Wheelless Robots Are on the Way
C.How Robots Deliver PackagesD.Packages Will Be Delivered by Robots

文章大意:本文为一篇说明文。因为时间、气候变化、全球化和旅游业,历史文化遗产正在遭受着前所未有的破坏,文章主要介绍现代技术(AI和VR)在文化遗产的保护方面的应用。

【推荐3】Wherever we go, we are surrounded by history. Across the globe, cultural heritage is passed down through the generations. It is in the buildings and structures around us. It is in the arts and artifacts (手工艺品) we treasure. It lives in the languages we speak and the stories we tell. But today, it is under attack as never before. Not only are the damages of time threatening our cultural heritage, but climate change, globalization and tourism are all exacting a heavy price. Technology is now the most important weapon in the battle. Here’s how technology is preserving our cultural heritage.

As you can imagine, creating the replicas (复制品) by 2D images is extremely time-consuming. Increasingly, artificial intelligence (AI) algorithms (算法) allow millions of images to be stored in a matter of hours. AI will also make restoration and preservation of existing cultural heritage far easier and better than previous methods.

Virtual reality (VR) technology will play a leading role in preserving our cultural heritage in the coming years. Many of the most important sites and architecture are easily damaged. Human interaction with these locations is doing a great deal of harm. Wastes pile up everywhere, causing serious problems. As more cultural heritage sites and objects are digitally mapped and recorded, VR technology will increasingly become the way that people experience them. We’ll all finally be able to walk through places, look at (and touch) artifacts and works of art without ever seeing them with our own eyes.

Finally, our cultural heritage will be preserved by technology. Efforts in research, data sharing and project work will help promote and preserve the cultural heritage of countries all across the world.

1. What does the underlined word “exacting” in paragraph 1 mean?
A.demandingB.cuttingC.receivingD.paying
2. What is the advantage of AI in preserving cultural heritage?
A.It makes preservation safer.B.It produces 2D images.
C.It makes restoration easier.D.It creates replicas in seconds.
3. How does VR help to preserve cultural heritage?
A.By reducing human impact on the site.
B.By recycling huge amounts of waste.
C.By forbidding visitors from touching artifacts.
D.By educating people about the sites’ importance.
4. What is the author’s attitude towards AI in cultural protection?
A.Ignoring.B.Supportive.C.Objective.D.Disagreeing.
