【推荐3】Language is part of our daily lives, no matter where we live in the world. Similarly, music is a part of many people’s lives.     1     Here are some of their similarities.

Both language and music have a writing system

    2     Similarly, we use notes to keep a record of music. Just as you are reading this collection of letters on the paper and find meaning in it, musicians read notes and create meaning in the form of music which we can hear. By reading pieces of text or music, we are able to share experiences through time. For example, we can read the ideas or hear the composition of someone who lived hundreds of years ago, which is really quite exciting.

You can make a good guess at where someone is from by listening to the language they use. In the same way, we know that styles of music are different around the world, which gives us the opportunity to explore many different cultures through their music and providing us with music for every situation.

Both share emotion

How do you know that I am angry? Of course, you may be able to see it in my face, but you will know for sure through my words.     4     Music can show you exactly how the composer was or is feeling, and allows us to share that emotion. When you feel happy, you might want to sing and dance to a happy song.     5    

【推荐1】On September 26, 2022, NASA successfully completed its Double Asteroid Redirection Test (DART) mission by intentionally crashing an unmanned spacecraft into the asteroid(小行星) Dimorphos. The goal was not to destroy the asteroid but to change its orbit. With the successful mission, NASA proved the concept that this technique could keep a potentially dangerous asteroid from crashing into Earth in the future.

Dimorphos is a small asteroid orbiting the larger asteroid Didymos. NASA noted that Dimorphos is not a threat to Earth, but because it passes relatively close to Earth, it was chosen as the target for the test mission. Although the intended crash should change the asteroid’s position slightly, it will add to a major shift over time. “If you were going to do this for planetary defense, you would do it 5, 10, 15, or 20 years in advance for this technique to work,” said NASA program executive Andrea Riley. “This is why we test. We want to do it now rather than when there’s an actual need.”

Asteroids can pose a significant threat to planet Earth. For example, around 66 million years ago, an asteroid around 6 to 9 miles across struck the Earth in what is now the Yucatan Peninsula. The resulting impact was so catastrophic that it caused one of the largest extinction events in Earth’s history. Therefore, DART’s success is an important step forward in protecting the planet from potential damage from an asteroid. This shows humans are no longer powerless to prevent this type of natural disaster.

The DART spacecraft was launched by NASA on November 24, 2021. It was accompanied by another craft called LICIACube, supplied by the Italian Space Agency, and separated from DART just 15 days before the crash. LICIACube remained in orbit around the asteroid and took photographs of the crash and material ejected (弹出) from the asteroid’s surface.

For many, even a small amount of alcohol can cause unpleasant effects. Most commonly, their face, neck and sometimes their whole body turn red. People might also feel uncomfortable and sick to their stomach. They might experience a burning sensation(感觉), increased heart rate, shortness of breath and headaches. The cause is a genetic difference that they are born with called an ALDH2 deficiency(缺乏). It prevents their bodies from treating alcohol the way other people do. But the effects might be more serious than just a red face. Researchers warn of a link between this condition and an increased risk of cancer of the esophagus(食道) from drinking alcohol. The more alcohol people with this deficiency drink, the greater their risk is. In Japan and South Korea, for example, many people have the deficiency but still drink heavily. Researchers have found that these drinkers develop a form of esophageal cancer six to ten times more often than those without the deficiency.

Esophageal cancer is one of the deadliest cancers. It can be treated when found early, but once it grows the chances of survival drop sharply. The researchers estimate that at least five hundred forty million people have the deficiency, about eight percent of the world’s population. Philip Brooks is a researcher at the National Institute in the United States. He says it is important to educate people about the link between the alcohol flushing effect and esophageal cancer. He says doctors should ask East Asian patients about their experiences with facial flushing after drinking alcohol. Those with a history of it should be advised to limit their alcohol use. They should also be warned that cigarette smoking works with the alcohol in a way that further increases the risk of esophageal cancer.

【推荐3】Healthy, shiny hair is an attainable goal for many people. What you eat can bring luster and strength back to your hair. A balanced diet filled with so-called superfoods like certain fruits and oils treat your hair from the inside out.

Oils

The omega-3 fatty acids in eggs, walnuts, and fatty fish like salmon help make hair shiny. These oils can also be obtained through some vegetable oils or flaxseed oil, but are found in higher amounts in oily fish and eggs. The protein in these foods also helps hair grow strong and healthy. Also found in eggs are B12 and biotin, both of which are essential for healthy skin, nails, and hair.

Avocado

Avocados contain high amounts of vitamin E. Only 2 ounce of a medium-size avocado contains 8 percent of your daily recommended intake of vitamin E. If you don’t like to actually eat avocado, you can make an avocado mask to put on your hair. Vitamin E helps to keep your hair color bright and prevents split ends.

Coconut Oil

The medium-chain fatty acids in coconut oil are used differently by your body than other saturated fats. An added benefit of coconut oil is its ability to make your hair shiny and healthy. Use coconut oil to cook your chicken or seafood, add it to your salad, or put it directly on your hair as a mask. Coconut oil’s anti-fungal agents also help protect against and treat dandruff and other scalp problems.

Vitamin C Fruits

Fruits high in vitamin C, such as oranges, peaches, pineapples, strawberries, and kiwi - help maintain healthy hair and fight against free-radical damage from the environment to protect your hair against pollutants. Make sure to eat lots of fruits high in vitamin C. You can also apply the juices of these fruits directly to your hair by mixing it into your shampoo.
