5 . The official opening of Beijing Daxing International Airport caps a long design and building process. Designed by the late architect Zaha Hadid and her Chinese partners, the airport is built for the future, having a terminal the size of 97 soccer grounds--as well as customer-service robots that provide travelers with flight updates and airport information.

Called "starfish" by Chinese media for its shape of five concourses（大厅）connected to a main hall, Daxing Airport aims to reduce the walking distance for passengers. The airport authority has promised a distance of no more than 600 meters（about eight minutes of walking）between security checkpoints and the remotest boarding gate.

This new modern airport employs a special intelligent lighting system, supported by eight big C-shaped columns that let in the sunlight, brightening the architecture and structure. Therefore, it minimizes the need to use electric lighting.

To offer a more refreshing travel experience, five outdoor courtyards with the themes "Silk Garden". "Tea Garden", "Porcelain Garden", "Countryside Garden" and "Chinese garden" feature at the end of the five departure lounges（等候室）for use by passengers waiting for their flights. Travelers will be scanned on cameras using facial recognition. Counters will be fully automated to capture face photos and relay them in each part of the journey through the airport, including security and the departure gate.

China is projected to overtake the United States as the world's biggest air travel market by 2022. The "modest" initial operational target at Daxing is to accommodate 72 million passengers and 2 million tons of goods annually by 2025. The ambitious master plan calls for the building of a total of seven runways, and moving at least 100 million passengers and 4 million tons of goods a year through the airport.

In March 2019, when Sara Cook first got a letter in the mail telling her that someone had paid off a large amount of her medical debt, she simply couldn't believe it. Cautiously, she called the number listed on the letter. What she learned was that this was not a scam. It was 100 percent real.

A remarkable nonprofit called RIP Medical Debt had indeed paid $5,000 toward her bills. The organization didn't take care of all the debt she'd accumulated from several back surgeries, but the former nurse was still moved by the gesture. “I felt really loved and blessed,” she says, “knowing that complete strangers just did that out of the goodness of their hearts.

Craig Antico and Jerry Ashton do have good hearts. They're also former collection agents who have seen how heavy health-related debt has destroyed lives. “I never thought about all the hardship of the people who couldn't pay. Now I'm trying to find the people who need help.” said Antico. They got their money from individuals and charities that support RIP's mission.

RIP researches potential receivers based on three criteria. First, they look for people who make no more than two and a half times the amount established as the federal poverty level. Then they screen for those whose debt is equal to 5 percent or more of the gross income (总收入). Third, they look to see whether a person can pay off debts.

For the people who do qualify, RIP's help is life-changing. “After their letter, I realized that my life really wasn't so hard,” says Cook, “I may never be able to work as a nurse again but I can sit at the school library and help kids read or serve up food in the soup kitchen. When people do something out of the kindness of their hearts, sometimes they may wonder: Does it really make a difference? I want people to know that this has a positive impact.”

7 . How to Use a Modern Public Library

Has it been a while since your last visit to a public library? If so, you may be surprised to learn that libraries have changed for the better. It’s been years since they were dusty little rooms with books. They have transformed themselves into places where you can develop your love of knowledge meet interesting people, or find out how to start a business.

Check out a book. While libraries still loan out(出借)books, you’ll find it easier to get a copy of whatever you’re looking for, thanks to a cooperative network of area libraries. Via such networks, libraries share their books with each other through the use of delivery vehicles. Once the book you’ve requested is delivered to the nearest branch, they will inform you by e-mail, so you can pick it up.

Check out other items. The library is now a multimedia zone, loaded with information in many formats(载体形式). You can borrow movies on DVDs, music on CDs, and popular magazines. Some libraries even loan out toys and games. If a popular magazine you want isn’t offered and the library keeps a list of such requests, they may bring it in when enough interest is shown.

Join targeted reading groups. Libraries will often hold reading-group sessions targeted to various age groups. Perhaps you’d like to learn a language or improve your English. The library may sponsor a language group you could join. If you have difficulties reading, ask about special reading opportunities. Your library might be able to accommodate you. And you might find it relaxing to bring your small kid to a half-hour Story Time while you sit quietly in a corner with a good book.

Start a business using the help of your local library. If you want to have a business of your own, your local library can become a launch space for it. In library books and computers, you can find information on starting a business. Many libraries will help you with locally supplied information about business management shared through chambers of commerce(商会)and government agencies, and they will offer printing, faxing and database services you need.

8 . The United States Department of Agriculture has a program called Wildlife Services. Its job is to help protect agricultural and other resources. Often that means helping farmers deal with unwelcome visitors. This organization has experts from different fields and it has set up thousands of inquiry centers all over the country where farmer can explain their difficulty and get practical help.

One example from Wildlife Services of its work involved a farmer in Washington State in the Pacific Northwest. Several years ago, thousands of Canada geese landed on his fields. The geese began to eat his carrot crop. Biologists from the program suggested that the farmer use noise-making devices and other measures to scare the large birds away. These efforts succeeded, which made the farmer quite happy. Wildlife Services also has a livestock protection program. The program just offers suggestions to keep those unwelcome visitors away instead of killing them. The Wildlife Services program is part of the Animal and Plant Health Inspection Service, or APHIS. APHIS offers some suggestions of ways to keep away predators. For example, try to keep food and water safe from wildlife. Fences may help keep out wolves, especially if the fences are at least two meters high.

Experts suggest providing secure shelter for chickens, sheep and other animals that could be attacked. They also suggest using lights above places where these animals are kept. And they advise people who see wolves to chase them away by shouting, making loud noises or throwing rocks. And to protect livestock, consider using guard animals such as dogs and donkeys, which are very effective.

For home gardeners, a two-meter fence might help keep out deer. To keep out rabbits, a wire fence has to be only about a half-meter high. It should extend fifteen centimeters underground to keep rabbits from digging under it. If snakes are a problem, remove dead trees and cut high grass to destroy their hiding places. Due to its effective work, ever since the Wildlife Services was started, it has been well received by farmers all over the States and neighboring countries such as Canada and Mexico.

9 . ①What is a place where you could find old pictures of camels carrying people to Mecca, Saudi Arabia (沙特阿拉伯麦加),and also books about ancient Aztecs(阿芝 特克人) in Mexico ? It is all found in the World Digital Library (WDL). Its collection is available on the Internet.

②The librarian of the United States Congress, James Billington, established the WDL in 2009. And John Van Oudenaren is the director. They want it to include items that are both interesting and important, which encourages them to look for things from each country, each culture and each civilization. There are 170 partners in 79 countries sending material to it, including national or university libraries, museums and other cultural organizations.

③The library has 8,000 items, including whole books, ancient writings, music and photographs. Every item is annotated (注解)in the 6 official languages of the United Nations: English, Arabic, French, Spanish, Chinese, Russian plus Portuguese (葡萄牙语).

④Anyone may search the World Digital Library by subject, time period, kind of document or area of the world, whose website is www.wdl.org. Since 2009, 25 million people have visited the website from 250 places. The greatest number is from Spanish-speaking countries. The users include schools, researchers and anyone interested. A teacher from New York City said happily, “It is really wonderful to have a site where every kid in the class, no matter which country he/she is from or where his/her parents were from could search and find something about that country.”

⑤Mussa Maravl is a researcher for the WDL from Sudan, who works with all the materials that are in Arabic. He recently published rare photographs of Mecca from 1885. “These camels are, you know, lying their heads on the ground, which is very unusual for a camel. It means these camels have traveled so long, so far and half of those are very thin, too, meaning they have   exhausted all the fat they have stored.”

⑥Mussa Maravl believes the library provides tools for understanding, especially among Arabs, Muslims and the United States. He says the WDL is posting many items about important developments in Arabic and Islamic science.
