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 studys 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 cant 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 bodys 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.26 . According to the new study, where does our fat go when we exercise a lot?AIt is changed into heat and given off in the air.BThe body burns it.CThe fat fairy comes and takes it.DMost of it is breathed out as carbon dioxide.27 . What will happen to people if they breathe more than the bodys metabolic rate?AThey will put on more weight.BThey will feel comfortable.CThey may become unconscious.DThey may not lose weight at all.28 . Which of the following is a better way to lose weight?ASitting still and breathing more.BSleeping a lot and breathing a lot.CEating less and exercising more.DEating more and doing some light exercise.29 . Which is true according to the study from University of New South Wales?AThe fat is changed into heat and released in the air.BMost of the kilograms of fat as they are lost are breathed out as carbon dioxide.CPeople can see the carbon dioxide gas we breathe out.DIf we breathe more than the bodys metabolic rate, we will feel good.30 . During a week , how much carbon dioxide does a 70kg person breathes out?A240gB200gC1400gD1680gYou might have learned in your science classes that the sun is quite large and heavy. What if you heard that weve found a black hole that contains the mass (质量) of nearly 70 suns?Chinese scientists used LAMOST, a powerful Chinese telescope (望远镜), as well as telescopes in Hawaii and the Canary Islands, to make this discovery.According to Einsteins theory, black holes come from dying stars. The star collapses (坍塌) into a small point with a lot of mass and strong gravity (引力). The strong gravity of the black hole allows it to pull other things in and “eat” them. Scientists search for black holes by looking at x-rays that are released when they “eat” nearby stars. However, when black holes are inactive, this method doesnt work.This time, the researchers looked at stars that orbit invisible (看不见的) objects. These objects, they believe, cannot be anything but black holes. After calculating (计算) the speed of one particular star in a star system named LB-1, the scientists figured out that it was orbiting (绕轨道运行) a stellar-mass black hole.The black holes mass is about 70 times the mass of our sun. According to current theory, this black hole shouldnt even be able to exist. It was previously believed that the mass of such a black hole cannot be bigger than that of 25 suns. Stellar (星球的) winds blow away the heavy elements that are left behind when a star dies. But somehow, this black hole kept most of its heavy elements.Researchers said it is possible that the black hole formed out of two large stars that died and merged (结合) together.The discovery is also inspiring some researchers to revisit their previous studies. “This discovery forces us to re-examine our models of how stellar-mass black holes form,” University of Florida physicist David Reitze was quoted as saying in a press release.31 . How did Chinese scientists find the stellar-mass black hole?ABy looking at stars moving away from the black hole.BBy studying x-rays that came from the black hole.CBy calculating the gravity of a nearby black hole.DBy looking at the speed of a star that orbits it.32 . What does the underlined word “inactive” mean in Chinese?A积极的B不活跃的C快速的D活泼的33 . What do we know about the black hole?AIt is much heavier than the sun.BIt is moving faster than the sun.CIt hasnt “eaten” any stars.DIt will disappear soon.34 . What is the last paragraph about?AThe importance of this discovery.BPrevious studies on black holes.CThe formation (形成构成) of stellar-mass black holes.DThe preparations that were done before making this discovery.35 . What do we know from the story?ABlack holes are usually heavier than 25 suns.BWe cannot believe current scientific theories.CBlack holes can form after stars die.DStellar-mass black holes contain no heavy elements.Dear Mr. Li，Im not happy.

Here are some messages you may be interested in.Take off your shoes or not. Its bad manners to take off your shoes at the door of a London dinner party. But in Asia you should take off your shoes before going into a home, or people will think you are not polite enough. What you should do instead: If you see a row of shoes at the door, take off your shoes. If not, keep the shoes on.Pay attention to the environment when you talk. In some counties, like Japan, dont start talking while everyone else is having dinner. Youll meet with silence-not because your group is unfriendly, but because mealtime is for eating , not for talking. Also dont talk loudly in some public places like museums, restaurants in Europe. What you should do instead: Keep quiet when having dinner! Speak in a low voice in public places.Know your right from your left. Some cultures in Africa and the Middle East still like to eat in traditional ways-using their hands. When people eat in this way, food is often offered for several people to share at the same time. That is why its important to wash your hands before eating. While eating, you have to follow the rule: Eat using your right hand, and use your left hand to do other things. Another rule to remember: Eat the food thats closest to you. Dont put your hand into the center of the table. What you should do instead: Follow the others and use your right hand. Even children who are left -handed in this culture are taught to eat with their right hands. If you really cant, make an explanation to others before you eat.Title: Different Cultures in Different59 .
