Once upon a time, a king dressed up and went to a local village. He placed a large stone in the middle of the main road and hid gold coins under the stone. Then he hid behind a huge tree and watched.

The first person down the street was a milkman with his car (小车). He crashed into the stone and the milk spread all over the ground. "What fool put this stone here? "he shouted. He picked himself up and angrily went away.

After a while, a group of women came along, each balancing a pot of water on her head. One woman tripped over (绊倒) the stone and her water pot went crashing to the ground. She picked herself up and walked away in tears. Neither she nor her friends thought about moving the stone out of the road.

The king watched all day as many people complained about the stone, but he found nobody was willing to move it. The king wondered, "Is there no one in this village who feels anyresponsibilityto keep their neighbors from harm?"

Just then, the king saw a young girl coming along. She was the daughter of a local farmer. She had been working all day and was very tired. But when she saw the stone, she said to herself. "This stone is a danger to anyone who comes down the road after dark. I'll move it out of the way."

After a great deal of effort, the girl finally succeeded in moving the stone to the side of the road. Imagine her surprise when she saw the gold coins where the stone had been!

Just then, the king stepped out from behind the tree. "Oh sir," the girl said, "Is this gold yours? If not, we surely must find the owner, for he will certainly miss it."

The king said, "My dear, the gold is mine, but now the gold is yours, because you are the only person who has learnt the lesson I want to teach my people. Nothing good can come to a nation whose people only complain and expect others to solve their problems."

Qomolangma is the world's highest mountain. You may have learned from your textbooks that its height is 8,844 meters. But not all sides are in agreement on this. Different researchers have given different results. In addition, the height of the mountain can change over time.

That's why a 30-member Chinese survey team set out to reach the peak (顶峰) of Qomolangma to re-measure its height on May 6. They are equipped with the latest technology, including a global navigation satellite system receiver and a radar (雷达).

It is not an easy task. The average air temperature on the mountain is —29℃—four degrees lower than in Antarctica (南极洲) -and powerful winds blow all the time. In such bad conditions, surveying drones (无人机) cannot work at the peak of the mountain. That's why it's still necessary to send human experts to the peak to get believable results.

But does a difference of a few meters really matter when it comes to a high mountain?

In fact, measuring the height of Qomolangma is about more than just getting one exact number. Mount Qomolangma is at the point where the Eurasian plate meets the Indian plate.Itformed 38 million years ago as the two plates hit each other. Changes in the peak's height can show whether the two plates are heading toward or away from each other. This can help us understand the movement of Earth's crust (地壳).

The survey team will also get firsthand information about environmental conditions at the top of the mountain. This will help us understand how climate (气候) change has affected the Tibet-Qinghai Plateau (高原).

What's the first thing that you notice when passing your favorite restaurant? The smell of fresh pizza? Or the sight of your favorite desserts? Food that looks and smells good will probably taste good, but what about the sound?

Some scientists now believe that the taste of food can change when you hear different sounds, but it has to be the right sound. When you turn on a microwave (微波炉) with popcorn (爆米花) in it, it soon starts to pop. Do you think "that sounds tasty?" Not really, you probably think it's nearly ready. But when you smell it, you know it is delicious. Hearing the popcorn makes you think about it, but smelling it tells you that it tastes good. So what are the sounds to change the tastes of the things?

In an experiment in a fish restaurant, customers listened to the sound of the seaside while eating. Did it make any difference? Yes. Listening to the seaside seemed to improve the taste of the food - It was fresher and saltier. When the restaurant tried the same experiment with the sound of farm animals, there was no difference in taste. The results are useful for restaurants.

Scientists are also setting a connection between food and the sound that the packet makes. Pick up a packet of potato chips, what does it sound like? Experiments show that if the packet makes a right sound, customers will think the potato chips are fresher. So one manufacturer (生产商) has started to change the material that they used to make their potato chip packets.
