1 . Gitanjali Rao, Colorado teenager who invented mobile device to test for lead (铅) in drinking water, was Time’s Kid of the Year for 2020. The magazine announced the award on Thursday, citing Rao’s ability to apply scientific ideas to real-world problems and her desire to motivate other kids to take up their own causes.

It was just the latest recognition for Rao, 15, who was named last year to the Forbes 30 Under 30 list. She won praise in 2017 after she responded to the water crisis in Flint, Michigan, by creating a device named Tehys, using carbon nanotube sensors to detect (探测) lead in water. The Lone Tree, Colo., native was named America’s Top Young Scientist when she was in the seventh grade. She went on to cooperate with scientists in the water industry to try to get the device on the market.

More recently, Rao has developed a phone and Web tool named Kindly, which uses artificial intelligence technology to detect possible early signs of cyberbullying (网络欺凌).

“You type in a word or phrase, and it’s able to pick it up if it’s bullying, and it gives you the choice to edit it or send it the way it is,” Rao told Time. “The goal is not to punish people. As a teenager I know teenagers tend to become very angry sometimes. Instead, it gives you the chance to rethink what you’re saying so that you know what to do next time around.”

Rao was chosen in part because of the way she has followed up her technical work with efforts to get other young people to work on solving the problems they see.

“I don’t look like your typical scientist. Everything I see on TV is that it’s an older, usually white man as a scientist,” she told Time. “My goal has really shifted, not only from creating my own devices to solve the world’s problems, but inspiring others to do the same as well. So I really want to put out that message: If I can do it, you can do it, and anyone can do it.”

2 . After decades of exploring the moon, a dramatic vision is finally becoming reality. The Guardian recently reported that a project called Lunar Codex is planning to send and store over 30,000 works on the moon from artists, writers, filmmakers, and musicians from over 150 countries and regions. The goods to be stored range from novels and paintings to music, films，and even soil from Earth.

In fact, this is not the first time that people have tried sending human legacies (遗产) to outer space. In 1969, the Apollo 12 mission carried a ceramic piece with drawings. In 1971, the Apollo 15 staff left a sculpture to honor those who had died in space exploration. What’s more famous is the Golden Record carried by spacecraft Voyager 1 and 2 from NASA in 1977, which contains human language, music and images. For example, a piece of Chinese guqin music, called Flowing Streams was included in it.

Although we don’t know who determines which symbols of human legacy get sent out to space in most projects, it’s obvious that the criteria keep changing. In the past，space heritage products only focused on space-related works; but gradually, more human-related contemporary goods which held great importance in their respective eras have been added to the list. In the Lunar Codex, films, diverse art and literary works produced by women, disabled artists, and even AI have been collected for the first time to be sent to the moon.

These changing criteria also leave space for ordinary people to imagine and think. Many people are now trying to store their DNA information digitally. Will people be able to find even more surprising and inventive ways to preserve their legacy in the future? Only time can tell.

1. What is the goal of the project?

A．To make the moon livable.	B．To show respect to artists.
C．To enrich the life of astronauts.	D．To preserve human legacies.

2. How is Paragraph 2 mainly developed?

A．By explaining reasons.	B．By giving examples.
C．By making comparisons	D．By analyzing previous data.

3. What does the change of the criteria reflect?

A．AI technology is amazing.	B．The selective rules are strict.
C．Human civilization is inclusive.	D．Space-related works are popular.

4. Where does the text most probably come from?

A．A magazine.

B．A textbook.

C．An advertisement.

D．A poster.
