2 . Can you imagine a civilization without music? Impossible, I would say. In addition, history shows that every culture on this planet has used music all the way.     1    .

They say that music is good for the soul, but what about the heart?     2    . Heart patients were observed at Massachusetts General Hospital. They were recovering from heart surgery. Some patients listened to Mozart’s piano sonatas for half an hour every day. These patients were the ones who had improved heart rates and lower blood pressure compared with those who never listened to any music at all.

Patients suffering from pain have found relief from listening to music. Classical music seems to be the best choice and Mozart and Bach are the most suitable. But heavy metal and other techno sounds can actually excite patients and cause irregular heartbeats, so they are not recommended.

Studies show that simply playing soft and relaxing music while eating can have a controlling effect on how full you feel.     4    .

There was a lot of publicity about the “Mozart Effect” which showed that a group of college students did better at math while they were listening to some classical music.     5    .

3 . It’s happened to all of us: a song comes on the radio, and we are immediately transported back to a time in our past.     1    

There are a few things that connect tunes with our memories. Music is often a necessary element of many important life events, and it is also very effective in arresting our attention.     2     Besides, the emotional nature of music helps make it particularly memorable.

We often become familiar with a piece of music because we hear it as background music. The more familiar a piece of music is, the more effective it is in bringing back memories.     3     The reason is that we are far more likely to hear a song over and over again than to watch a film or a TV programme in the same way.

Tiffany Jenkins, writing for a culture column, has a different opinion:     4     She tells us how throughout history oral cultures have passed important knowledge from generation to generation through songs because of this characteristic. The rhythm (韵律) and rhyme in lines of songs all serve as memory aids.

    5     This fact corresponds with what many experts call the “reminiscence bump (怀旧性记忆)”, where older adults (over forty) have increased recollection of events that occurred during their adolescence and early adulthood.

It’s clear that our memories and music are closely linked — to the point that music is being used to help Alzheimer’s disease sufferers access memories that they thought they had lost.

6 . Music is present in any part of the world, and it is appreciated and felt everywhere. Without its presence, life could be boring. Studies show that music is good for your body and mind.     1    

Music can increase pain management. Listening to music can help increase your pain tolerance (耐痛性).     2     Listening to music can help you gain a sense of control over your ability to deal with pains. If you have a certain pain, for example, listening to music that you enjoy can help reduce the pain that you experience.

●    3     Listening to certain types of music, such as relaxing music, can naturally reduce both your heartbeat rate and breathing rate. Additionally, music has shown promising results as a treatment for heart disease. Whether it involves listening to music or composing music, the calming effect that music produces further improves your heart’s health by supporting it throughout the healing process.

●Music can reduce anxiety and depression     4     When it comes to anxiety and depression, music treatment can help to reduce the amount of stress hormones. For example, listening to music that you enjoy can naturally decrease the amount of cortisol (皮质醇) that your body releases.

●Music can improve self-expression and communication. Self-expression and communication are an important part of the human experience, especially when it comes to basic emotional and mental health needs.     5     By listening and singing along to music, kids who struggle to interact and communicate with others can practice using the very skills needed to do so.

8 . Music influences your emotions. In turn, your emotions influence your behavior. One of these is your food intake.     1     What does science say about this subject?

Researchers at the University of Arkansas studied how music influences people when they eat in a restaurant. For the study, they used four types of music: jazz, classical, rock, and hip-hop. Their results showed that people had more appetite when they listened to jazz music while they ate.     2     This has a lot to do with emotions. For instance, when you listen to music with harmonic rhythms like jazz, you feel happier. This increases your appetite.

However, another study published in Psychological Reports suggests it isn’t only increased appetite that causes people to eat more.     3     A more stimuli-filled environment makes you eat more. In fact, they tend to urge you on to eat and even “encourage” you to eat faster. On the other hand, if the atmosphere in the restaurant is relaxed, you’re likely to feel more relaxed and spend more time enjoying yourself. For this reason, you’ll tend to eat less.

Besides, the study conducted by the Journal of the Academy suggests that the volume of music can also have an effect on how you eat. More specifically, the study states that, with low-volume music, you eat better because you make healthier choices. On the other hand, the study claims that music at high volume increases stimulation and stress.     4    

For this reason, restaurants should consider the fact when thinking about the optimization of their products and services.     5     They equip themselves with the technology needed to provide memorable experiences through music, greatly strengthening their relationship with the customer.

9 . Music has long been considered to be an enjoyable pastime for many people．     1     The mental health benefits from music can't be argued．Music could also be helping you with many other health problems behind the scenes．

    2    However，for the same reason，music can be very beneficial if one is in pain．By distracting （分心） the mind from the pain，music，people say，can lower stress and anxiety levels．This，of course，can lead to less pain．

Many people enjoy relaxing music in the evening prior to going to bed．    3    While the validity of the idea is still being assessed，the lowered stress can even be tied back to blood pressure．Similarly, according to researchers，listening to just 30 minutes of soft music every day may help with healthy blood sugar levels， through the lowering of stress and anxiety．

When it comes to heart health，there is speculation （推测） that it's not the style of music， but rather the tempo that makes it so good for your heart health．In one European study，participants listened to music as the researchers monitored their heart rates and blood pressure．    4     On the other hand，when the music slowed，the participants' stress and anxiety levels became lower and the effects on heart rates appeared to follow suit．

    5    But there is a whole range of other health issues that turning up the radio could be beneficial for，which is what makes music so valuable．
