Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Almost 80 percent of people feel shy at some point in their lives. These days, shyness is becoming more and more common. Now, scientists are trying to understand shyness. They have some interesting ideas about why people are shy.
Is it possible to be born shy? Many scientists say yes. They say 15 to 20 percent of babies behave shyly. These babies are a little quieter and more watchful than other babies. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is genetic.
Family size might cause people to be shy as well. Scientists at Harvard University studied shy children. They found that 66 percent of them had older brothers and sisters. As a result, they became shy. At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play by themselves. They are not able to learn the same social skills as children from big families.
You may also be shy because of where you were born. When scientists studied shyness in different countries. They found surprising differences. In Japan, most people said they were shy. But in Israel, only one of three people said so. What explains the difference? One scientist says the Japanese and Israelis have different opinions of failure. In Japan, when people do not succeed, they feel bad about themselves. They blame（责备）themselves for their failure. In Israel, the opposite is true. Israelis often blame failure on outside reasons, such as family, teachers, friends, or bad luck. In Israel, freedom of opinion and risk taking are strongly supported. This may be why Israelis worry less about failure and are less shy.
For shy people, it can be difficult to make friends, speak in class, and even get a good job. But scientists say you can get over your shyness. They suggest trying new things and practicing conversation. And don't forget — if you are shy, you are not the only one.

Can you recognize (辨别) AI-made pictures among real ones? Mark Zuckerberg wears a pink coat and walks in the fashion show. Former US president, Donald Trump, falls over while {#blank#}1{#/blank#} is getting arrested (逮捕). These pictures have {#blank#}2{#/blank#} popular online recently. They have one thing in common—they are fake (假的), but they look real.
AI tools, like Midjourney and DALL-E, {#blank#}3{#/blank#} create such pictures. Simply type in what you want and the picture comes out in a few minutes. People have never been {#blank#}4{#/blank#} worried than today about the fake news.
However, AI tools are not perfect. News medias, including the Washington Post and the Paper gave some {#blank#}5{#/blank#} on recognizing fake pictures.
One way is to look at hands. Human hands are often {#blank#}6{#/blank#} incorrectly by AI. The photos AI uses to learn often show hands in different ways, so it isn't sure what a "hand" {#blank#}7{#/blank#} looks like.
The other way is to {#blank#}8{#/blank#} attention to the details. For example, people in an AI made picture may miss an earring or a part of their glasses. If there {#blank#}9{#/blank#} a text in a picture, the text is usually unreadable. AI is also terrible at dealing with the background. If there's a crowd in the image, {#blank#}10{#/blank#} faces in the corner are usually unclear—or they don't have a face at all!
