In a big amusement park, there was a group of students sitting on the ground. They were listening to a speech after spending a happy morning there. At the beginning of the speech, the speaker told them a story about himself. “When I was in middle school, our class was once asked to write about our dreams. That night I wrote down my dream of opening up an amusement park. However, my teacher gave me an “F” and told me to write it again,” the speaker said. “Her reason was just that it was impossible for a poor boy to make such a dream come true. I went back home and asked my father what I should do. He told me to make the decision by myself. So I decided to make no changes. My teacher can keep the “F” and I’ll keep my dream.”

“And what happened?” the students asked. All of them were curious to know more about the story.

“This is what is happening now. You are listening to my speech in my dream park,” said the speaker. “I told you the story in order to make you know one thing: follow your hearts, keep your dreams and never let others destroy your dreams.”

When the students were leaving the park, their teacher went over to the speaker. “Thank you, Mr. Black. I think my students have learned a lot from your speech. Here I have to say sorry to you. Some years ago, I was once a dream stealer and stole a lot of students’ dreams, including yours. Fortunately you had enough gumption and didn’t give up your dream because of me,” she said and then left.

When we exercise hard, we burn fat. But have you ever wondered where exactly the fat goes?

Some doctors think that fat is changed into heat and released in the air. Others think the body burns it. Some even joke that the fat fairy comes and takes it. That is why you always weigh less in the morning.

Now a new study from the University of New South Wales in Australia reveals the mystery. “the correct answer is that most of the mass is breathed out as carbon dioxide(二氧化碳). It goes into thin air,” says the study’s lead author, Ruben Meerman, to Science Daily. Scientists followed the atoms(原子) in 10 kilograms of fat as they are lost. They found that 8.4 of those kilograms are breathed out as carbon dioxide through the lungs. The rest of the weight —1.6 kilograms— becomes water that leaves the body in the form of fluids(液体) such as urine(尿), sweat, breath and tears. “None of this is obvious to people because we can’t see the carbon dioxide gas we breathe out,” said Meerman.

Does that mean you can lose more weight by breathing more? It is not as easy as you think. Breathing more than the body’s metabolic rate(新陈代谢) can make you uncomfortable. You may feel dizzy and become unconscious(无意识的), according the study. So how to lose weight healthily? The key is to eat less and move more. You many have heard this many times.

During a day, a 70kg person breathes out about 200g of carbon dioxide. So if the same person wants to lose weight, he or she can do some light exercise, for example, jogging. This can help lose 240g of carbon dioxide.

D.If we breathe more than the body’s metabolic rate, we will feel good.
