Do you often make the “V” sign when taking photos? You might have to do so less often from now on.

Experts (专家) say that it is possible to use the “V” sign to copy someone’s fingerprints (指纹). Someone could take your photo, zoom in (使画面放大) on your fingers, and then use AI technology to copy your prints.

Does that mean you should not make the “V” sign in photos anymore? Not really. The fingerprints in your photos must be clear enough to copy. If the photo is taken from 1.5 metres or less away, it is possible to copy your prints. But if the photo is taken from over 3 metres away, your prints won’t be clear enough to copy. The photos we put online are usually not clear enough to copy. But still, you should be careful.

Kate had a big, old apple tree in her backyard. The tree was full of apples. “Those apples look good,” she thought, “They should be ripe in a few days.”

Every day, Kate looked at her apple tree. Every day she saw more ripe apples. “I’ll start picking them tomorrow morning.” she told her husband (丈夫) Frank excitedly.

The next morning, Kate went out to pick the apples. “Oh, no!” she cried. “Someone has eaten a few of my apples!”

Kate picked enough apples to make a pie. “I’ll pick the rest (剩余部分) of the apples tomorrow.”

The next day, more apples were gone. Kate said, “I must find out who is eating my apples.”

That night the moon was full. Kate took a coat and went to the backyard. She sat still and quiet, watching the tree.

At last, Kate heard a noise. She saw it! A fox (狐狸) in the tree! It was carrying an apple in its mouth. “So you’ve been eating my apples!” Kate said. When the fox heard Kate, it came down from the tree and ran away quickly.

Kate ran back into the house and told Frank what she had seen. “How are you going to keep the fox out of your apples?” asked Frank.

Kate didn’t say anything.

The next day, Kate picked the ripe apples. She left a few on the tree. “I think we can share the apples,” she said with a smile.

A 15-year-old student from Sichuan named Wei Fang was preparing a talk on Western festivals. She searched online for information and made a PowerPoint slide(幻灯片). Zhu Hui her classmate. was doing his chemistry homework. But he couldn’t work out the last problem even though he had tried his best. So he took out his smart phone opened a special app and searched for the problem. Solutions appeared on his screen after several seconds.

Like Wei and Zhu,nowadays , many students do their homework with the help of the internet. They search for information online, or discuss with their classmates through QQ and WeChat.

“It's convenient. You don't have to wait for your teacher to explain it to you face to face. " According to Zhu. You can also learn by seeing how others work the problems out. What's more. it improves students' problem solving abilities. This is especially true for homework that requires some research work. “I am now quite skilled at finding information online, ” Zhu added.

However. this trend (趋势) also causes problems. Some lazy students just copy the answers from the internet without thinking on their own. Some even let their classmates do their homework for them. And their teachers may not know this.

But knowing how to use the internet is important. The key is to have good self-control. When you meet a difficult problem,think about it by yourself first. Be sure to understand the reasons behind the answers after you have turned to the internet,or you won't make any progress. If you are not sure about your self-control,ask your parents for help.

There are two ways of worshipping（崇拜）famous people. One way is just to follow them or talk about them with friends for fun. The other is a mote serious way. People have very strong feelings for them and think they are their friends. People who do so for fun are found to be happier. But those who have strong feelings for a famous person are perhaps to feel more lonely and worried.

“Worshipping famous people is not certainly a bad thing.” Dr. John, an expert（专家）said. “But like many things, overdoing it may not always be good for you.”
