For many teenagers, they might just do their homework and spend time with friends. Not so for Emma Yang. At the age of 14,the Hong Kong-born Yang has already created her own mobile app for Alzheimer's patients(阿尔茨海默病人), which Bill Gates likes. Yang named it Timeless. The AI technology has been used to help Alzheimer's patients identify people in photos and remember who they are.

The inspiration(灵感) to develop an app that would help Alzheimer's patients connect with their loved ones came to Yang at the age of 12,when her grandmother suffered from the similar illness.

"I wanted to create something to help people like my grandmother. I started learning coding(编码) when I was around 6,and later began developing games and websites," Yang said. The young software developer also said winning a competition led her to realize the influence of technology on people's life. Yang's father, who works in the technology industry, was the one who introduced computers and Scratch, a programming program aimed at kids, to her.

However, Yang's life as a young software developer has not been without difficulties. Many business-men didn't take her work seriously. Yang had to start an Indiegogo crowdfunding campaign(众筹) to support her Timeless app project. That effort raised more than $10,000.

"I think perseverance(坚持不懈) is really important," Yang said. "Never let anyone tell you that you shouldn't be in the field that you want to be in the most."

She encouraged other young people to believe in themselves, because the teenagers of today will be tomorrow's leaders.

Many people in America love Chinese food. However, their “Chinese food” is very different from ours. America is a melting pot(熔炉). People from around the world join together there. Many of them bring their traditions with them.

Chinese food arrived in America in the 1850s. At that time, many Chinese people who went to live in the US couldn't find a job. To make a living, some of them opened restaurants. Over the years, Chinese food has become more and more popular. However, many changes have been made according to American people's taste.

One of the changes is about the cooking methods. In America, many “Chinese dishes” are cooked through frying(油炸). In China, few dishes are cooked in this way. Stewing(炖), steaming and boiling(煮)are more common.

Another big change lies in the ingredients(原材料). Cooks in America often use onions and tomatoes in “Chinese food”. In China, these ingredients are used much less often.

In addition, traditional Chinese food uses more types of meat. Chinese people eat duck blood, chicken feet, pig ears and even snakes. Most American people wouldn't choose to eat these things.

Some popular "Chinese dishes" in America can't be found in China at all. For example, the Fortune(幸运)Cookie is an American invention. It is a sweet, crisp(脆的)cookie which contains a piece of paper with some lucky words on it. Fortune cookies are often served in Chinese restaurants, but no one has ever seen it in China.

1.When did Chinese food arrive in America?
