Have you ever imagined going to other countries without your paper Passport? That will soon come true. And your paper passport will become history. You may use their new kind of passport

    It's reported that Australia will be the first country to use the cloud passport. With the cloud passport, you don't have to take a paper passport with you all the time. The cloud passport will have your name, photos and other information. And if you go to other countries, you can just check the information on the computer.

    When you take a paper passport with you, you might lose it. But with the cloud passport, you don't have to worry about that.

    Do you think the cloud passport is a great idea? Perhaps you will have it in the future, too.

You are running in the playground. But then suddenly, you fall and hurt yourself. "Ow!" you cry. This sound is very familiar to us all. Crying out when we get hurt is a natural action. But have you thought about why we shout it out? And do people from different languages make the similar sound? 

Scientists now believe they've found out the reason: shouting the word "ow" partly stops pain messages from traveling to the brain. So by shouting it out, people can feel less pain.

The scientists tested how long volunteers could hold their hands in very cold water. In the first group, they were allowed to shout "ow" when they felt pain. In another group they had to stay silent. The results showed that volunteers were able to keep their hands in the cold water for longer when they were allowed to shout out. Shouting out "ow" helps humans feel less pain and add the time.

What's more, scientists have also found that different languages have similar expressions of pain. While cries of "ow" or "ouch" are heard in English, South Africans yell "eina".

These languages have one thing in common: when people shout them, the mouth simply opens, the tongue (舌头)lies flat and the lips (嘴唇) unrounded. It is a simple sound that requires little control, so it's easy to make a big sound. For the reasons, these sounds are useful to shout if we feel pain.

 It was Jimmy's birthday and he was five years old. He got a lot of nice birthday gifts from his family, and one of them was a beautiful drum.

" Who gave him that thing?" Jimmy's father said when he saw it." His grandfather did," answered Jimmy's mother.

" Oh," said his father. Of course Jimmy liked his drum very much. He made a terrible noise with it, but his father didn't mind. He was working during the day and Jimmy was already in bed when he got home in the evening, so he couldn't hear the noise.

 But one of the neighbors didn't like the noise at all, so a few days later, she took a knife and went to Jimmy's house while he was hitting his drum. She said to him," Hello, Jimmy, do you know, there is something very nice inside your drum? Here is a knife. Open(打开) the drum and let's find it."
