Does the Body Burn Fat When You Are Hungry?

Your body stores fat as a way to help protect you against starvation if you can’t take in enough food. However, your fat reserve isn’t the first place your body goes for food. Instead, it reaches out for sugar for energy. 1.

Hunger is normally a reflection that your body has used up energy from recent food you ate and has moved onto getting energy from sugar in your blood. 2. The more sugar you take in, the more fuel your body has to use before it reaches out to the fat stores. If your body doesn’t have enough sugar to supply the energy it needs, it begins to burn fat when you’re hungry instead.

Missing meals and going hungry can change your metabolism (新陈代谢) so it stores fat instead of burning it. 3. However, if you skip meals for several days and severely lower your calorie (卡路里) intake, your body begins to store as much fat as possible.

4. Your body burns up sugar stored in your system and begins to burn fat as you continue to exercise. However, exercising when you’re hungry won’t help you burn fat faster. A recent study shows that the body burns the same amount of fat regardless of whether you are hungry when you exercise.

Staying hungry all day won’t necessarily help you burn fat, but cutting calories is key to losing weight. 5. Snack (吃点心) in between meals to keep your metabolism working all day, which helps it burn more fat than if it’s allowed to slow down when it’s not meal time. Snacking in between meals can help you control your meal sizes at meal time.

A. Exercise is key to burning fat.

B. You shouldn’t cut out food to cut calories.

C. This doesn’t happen in a day of missing meals.

D. Just being hungry doesn’t mean your body is burning fat.

E. If you take in less food than your body burns, you’ll lose weight.

F. Your body stores sugar in case you need it when you feel hungry.

G. Eat five or six small meals throughout the day instead of three large ones.

Most people are worried about the health of economy. But does the economy also affect your body health?

It does, but not always the ways you might expect. The data(数据) on how an economic downturn influences an individual’s health is mixed.

It’s clear that a long-term economic rise leads to improvements in a population’s overall health, in developing and developed societies alike.

But whether the short-term economic fall will damage your own health depends on your health habits when times are good. And economic studies suggest that people usually do not take care of themselves in good times—drinking too much, dining on fattier restaurant meals and skipping exercises.

“The value of time is higher during good economic times,” said Grant Miller, a professor of medicine at Stanford. “so people work more and do less of the things that are good for them, like cooking at home and exercising. ”

Similar patterns have been seen in some developing nations. Dr. Miller, who is studying the effects of fluctuating coffee prices on health in Colombia where coffee plays an important role in economy development, says that although falling prices are bad for the economy, they appear to improve the population’s overall health. When prices are low, laborers have time to enjoy their own life such as doing housework, exercising and taking care of their children, etc.

“When coffee prices suddenly rise, people work harder on their coffee fields and spend less time doing things around the home, including things that are good for their children,” he said.

Christopher J. Rohm, professor of economics at University of North Carolina. US shares similar ideas.

57. What would be the best title?

A. Does the economy affect your body health?

B. Does your life habit play an important role in economy development?

C. Economic rise leads to improvement in people’s health.

D. Coffee prices affect people’s health.

58. According to Grant Miller, it is implied that_______.

A. a long-term economic rise can damage your body health

B. a long-term economic fall can damage people’s body health

C. a short-term economic rise can improve people’s body health

D. a short-term economic fall can improve your body health

59. What does the underlined word “fluctuating” in the sixth paragraph mean?

A. lasting         B. changing        C. rising       D. falling\

60. Professor Christopher J. Rohm thinks that_________.

A. people work harder when it is in long-term good economy times

B. people work less when it is in short-term good economy times

C. people have more time to enjoy their own life in short-term bad economy times

D. people do less of the things around the home in long-term bad economy times

Much like a smartphone, your body will go to sleep when there are no new inputs. When you are on a bus, your senses will give you the same repetitive inputs. The streets will flow by, the engine adds constant white noise, you’re seated and not moving, and the smell... well you hope the smell doesn’t change.

Any repetitive input going to your brain will eventually be ignored and your brain will start going into a low energy state. The fact that you fall asleep quickly when closing your eyes on a bus is because you were already on the bus for a while and got used to all the repetitive sensory data.

When you go to bed, you have a lot of new changes. You are lying down, you wear different clothes, you feel the pressure of your covers, you go from bright to dark, noisy to quiet. All of these are new sensory inputs that your brain needs to get used to before going to sleep.

A laboratory experiment to investigate the effects of whole-body vibration (震动) on seated human alertness and sleepiness was carried out. Vibration was applied to the volunteers sitting on the vehicle seat on the vibration platform. Volunteers for this investigation included 18 young male and healthy university students. None of the volunteers had a history of neck pain, diseases of the cervical spine or musculoskeletal disorders. Seated volunteers were exposed to a Gaussian random vibration, with 1–15 Hz frequency bandwidth at 0.2 ms−2 r.m.s., for 20-minutes.

The results suggest that exposure to vibration even for 20-minutes can cause significant sleepiness. The data clearly show that exposure to vibration has considerable influence on subjective sleepiness levels, and more importantly, human reaction times and decrease of attention.

Drowsy driving has been reported to account for approximately 20% of accidents worldwide. In Australia, 16.6% of total road deaths were caused by sleep-related accidents in 1998 alone. It is well established that sleepiness caused by extended hours of driving has considerable influence on driver performance, therefore, compromising transportation safety.

These findings need to be further proved particularly in relation to driving behavior. This line of research can then assist in the development of practical and relevant guidelines for limitation of vibration exposure in the automotive industry, in an effort to reduce the burden of road accidents. That’s something for both car manufacturers and road safety experts to think about.

1.According to the passage, why do we fall asleep quickly on the bus?

A.Because we meet a lot of new changes.

B.Because the surroundings become quiet.

C.Because we get used to the repetitive sensory data.

D.Because our senses give us different kinds of inputs.

2.What is the purpose of the experiment?

A.To investigate people’s sleeping hours and situation.

B.To research whether vibration can affect people’s health.

C.To study the relationship between inputs and people’s attention.

D.To find out how shaking affects people’s sleepiness in the vehicle.

3.What can be inferred from the passage?

A.Sleepy driving is the main cause of road accidents.

B.The research has helped to reduce the burden of road accidents.

C.The findings of the experiment have been recognized by road safety experts.

D.The research results can give some implications to the automobile production.

4.What is the author’s attitude towards the findings?

A.Positive. B.Negative.

C.Disappointed. D.Indifferent.

When you close your eyes and try to think of the shape of your own body, what you imagine (or rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer（模糊的） than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size or shape.

When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.

The image you create for yourself has rather strange proportions（部分）; certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.

Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent(前后一致的) right and left and atop and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.

If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes （中风）which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.

1.According to the passage the “felt” image________the mirror image.

A．is precisely the same as         B．is as clear as

C．often differens from             D．is always much smaller than

2.Which the following staterants is NOT true?

A．The felt Image is much more important because it helps you locate new feelings.

B．When you are in bed with your eyes closed, it is not easy to imagine your image.

C．When you move, the “felt” image of yourself starts to become clearer.

D．The “felt” image is not so important as the mirror image.

3.If a man loses the ability to recognize his right side,________.

A．he can’t locate the doctor’s touch on his left side

B．he can’t locate the doctor’s touch on his right side

C．he loses his sense of touch on the left side

D．he loses feeling on both sides

4.What is this passage mainly about?

A．Stroke victims’ “felt” images     B．Stroke victims’ mirror images.

C．The importance of “felt” images  D．The importance of mirror images.

Being scared is not always a treat. When a balloon pops, we may jump. 1. How does the body triggered（激发）these reactions? When we encounter something we're not familiar with, our brain and body start making changes to help prepare us for the unknown. These changes are part of the body's " threat," "stress," or "fight — or — flight" response. This response is triggered by the five senses, which are always sending information to the brain. 2., the brain sounds a danger alarm. It releases chemicals into the bloodstream, and those chemicals act on different parts of the body. Once the body is alert（警觉的），the brain decides whether or not the danger is real.

3. It urges a person to hide, run away, or defend oneself. Faster heartbeat and breathing send more blood and oxygen to the muscles so they're ready when they're needed. Stress chemicals can make a person more alert. Our memories also help protect us. We keep a close eye on babies because they don't understand what might hurt them. As babies grow, they learn what's unsafe, and their brains store those memories 4.

Experiences can lead to long-lasting fears that may stop a person from trying new things. We're born with the ability to feel fear, but a lot of what we're afraid of is learned. A long-lasting fear can mean you’re had a bad experience, and your brain doesn't want you to have it again. Many people have beaten their own fears. Here's one method. 5., they learn the facts about anything that seems scary. Knowledge can help a person feel less afraid.

A. Instead of listening to their imagination

B. When they signal something unexpected

C. Our heart beats harder, and we breathe faster

D. Then their brains use fear to warn them of dangers

E. It's good to have a healthy sense of what's dangerous

F. Fear is a tool that the brain uses to keep the body safe

G. Memories are an important factor in fear-lasting experiences

From the moment you open your eyes in the morning, you can feel sweat running down your body, even if you' re barely moving at all. That's what most people in China felt like this summer. In fact, the entire northern hemisphere(半球)saw high temperatures in July.

The Arctic Circle was no exception(例外). Temperatures in the city of Norilsk, which is in the Arctic Circle, reached a record high of 32 ℃, The Atlantic reported. Temperatures there are usually just 10 ℃ at this time of the year.

The heat wave in the Arctic is mainly a long-term result of global warming, according to the Chinese Academy of Meteorological Sciences. In fact, while the whole world is getting warmer, the Arctic is warming twice as fast as the rest of the planet. This is called the polar amplification effect (极地放大效应).

The most direct impact of Arctic warming is the melting of Arctic ice. According to NASA, Arctic sea ice is now disappearing at a rate of 13.2 percent every 10 years. NASA said that if this continues, the Arctic will have no ice by the year 2040.

This has put some Arctic animals, like polar bears, in danger. The ice that the bears live on has shrunk(缩小), the Toronto Star reported.

Melting ice can also cause sea levels to rise in the long term. Since 1993, sea levels have risen at a rate of 3.2 cm every 10 years, the Guardian reported. Some countries, such as Tuvalu(图瓦鲁) in the South Pacific Ocean and Maldives(马尔代夫) in the Indian Ocean, are at risk of disappearing into the sea.

1.Which of the following is true?

A.Some countries in the ocean will disappear in 10 years.

B.China is the hottest in the northern hemisphere this summer.

C.The world gets warmer because of the heat wave in the Arctic.

D.The temperatures in Norilsk used to be lower than this summer.

2.What does the underlined word "this" in the third paragraph refer to?

A.The heat wave in the Arctic.

B.The result of global warming.

C.The Arctic getting warm faster.

D.Getting warmer in the world.

3.What may be the result of the melting of Arctic ice?

A.The polar will become dangerous.

B.There will be an end of water shortage.

C.Sea levels rise in the long term.

D.There will be no ice in the world by 2040.

4.What is the main idea of this passage?

A.Heat hits Arctic.

B.Arctic animals are in danger.

C.The world became hotter than before.

D.Some countries may disappear into the sea.

You will spend hours at the gym training your body, but do you ever think about training your brain? Here are four ways to keep your brain mentally (脑力上地) active and healthy.

Play games

Your brain is a muscle just like the ones in the rest of your body. If you don’t use it, you will lose it. For example, doing a crossword puzzle (纵横填字游戏) once a day is a good way to give the brain the exercise it needs. This kind of puzzle is good at training different areas of the brain. But remember that when doing this puzzle, you should gradually increase the complexity (复杂度); otherwise, it will become repetitive (重复乏味的) and stop being mentally challenging.

Talk aloud

Although it might sound strange to you, talking aloud is a great way to boost your memory. A good exercise to try is counting to 99 in threes as fast as you can.

Be a team leader

If you find you can do your work very easily, you should find a new task. It is important that your job should be mentally challenging. Complex jobs are often more challenging and make the brain work a little harder.

Learn a language

A study found that, compared with those who could speak only one language, the people who could speak two languages had a slower rate of cognitive (认知能力) decrease. Learning a new language is very challenging and it makes sure that different areas of the brain have their lights on.

1.What is the main idea of this passage?

A. Why you should train your brain.

B. How to be a good team leader.

C. Training the brain is more important than training the body.

D. How to make your brain healthy and work actively.

2.Which word can replace the word "boost" in the third paragraph?

A. Change.　　　　 B. Promote.

C. Decrease.　　　 D. Lose.

3.We should gradually increase the complexity when doing crossword puzzles because ______.

A. if we don’t use our brain, we will lose it

B. we should make our brain face different challenges

C. our brain is a muscle like other parts in our bodies

D. these puzzles can work on different areas of the brain.
