Any time we need a taxi, we can pull out our phone, tap buttons (轻敲按钮) and a car will show up. It’s amazing, right? But what happens to the elderly people who need a taxi but don’t know     1     to use a phone to book one? They can only wave (挥手) at the taxi passing by. I feel terrible every time I go to the hospital with my grandmother. There is     2     a long line of sick elderly people waiting for taxis. These people probably need a taxi badly. But they cannot get one     3     they do not know how to use a smart phone.

Over the past ten or so years, technology has     4     quickly. For most of us, it has changed the way we live. Today, shopping, banking and even work can all be     5     over the Internet. Many new apps have made life     6     for us younger people while they have made it more difficult for the older.

China has now come up with several ways to solve the problem, but bridging this “digital gap” (数字鸿沟) needs everyone’s action. Probably     7     over the age of 60, at one time or another, has called their children or grandchildren to ask for help with their smart phones. When they do so, we must be     8    . What may only take us seconds to learn can take them     9     to do so.

Next     10     your elders ask you for help with technology, remember how they spent countless hours teaching you to talk, walk, eat, etc.

Who do works created by AI belong to? Here’s an answer.

A man made a picture by     1     AI in February. And then, he posted the picture on Xiaohongshu. However, a lady used the picture in March and     2     off the Xiaohongshu watermark(水印).

The court (法院) found that this was against the law and     3     the lady must pay 500 yuan to the man.

The law is still not clear     4     AI-made works like this. Decisions on such problems are expected to change     5     over the next several years.

How to recognize an AI-made picture?

1. Look at     6    . AI often draws human hands wrong. Sometimes the number of fingers is not right, and sometimes the shape looks     7    . The photos AI uses to learn often show hands in different gestures (姿势), so it isn’t sure     8     a “hand” really looks like.

2. Pay attention to the details. For example, people in an AI-made picture may     9     an earring or apart of their glasses. If there’s text in an image, such as a poster, the text is usually unreadable.

3. Check the background. AI is also terrible at dealing with the background. If there’s crowd in the image,     10     faces in the corner are not clear or they don’t have a face at all!

Qian Xuesen is a famous Chinese scientist. He was     1     in Hangzhou, Zhejiang Province on December 11, 1911. After graduating from Shanghai Jiao Tong University in 1934, he got a chance to     2     in the USA. After he graduated, he became a     3     as well as a researcher who studied rockets and missile（导弹） theories（理论）.

When he was 44, he     4     to his motherland and China’s space research was almost a blank. In 1956, he     5     the first research institute（研究所）of rockets and missiles in China. He made such important contributions to the missile and space programs     6     he was honored as “The Father of China’s Missiles”. The Chinese people are     7     of him.

He passed away on October 31, 2009,     8     of 98, but all the Chinese will remember him forever. His devotion（奉献）to China was expressed in his saying, “My career is in China, my success is in China and my destination is in China!” When someone said he could make a lot more money if he stayed in the United States, he laughed and said, “My     9     name is Qian, but I don’t like Qian.” His spirit     10     encourages us to love our country and devote ourselves to science.
