Probably no other musical instrument is as popular as the guitar around the world. Musicians use the guitar for almost all kinds of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.

    Music experts do not agree about where the guitar was first played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than 1,000 years ago. Most experts say that the ancestor of the modern guitar was brought to Spain from Persia sometime in the 12^th century. The guitar continued to develop in Spain. In the 1700s it became similar to the instrument we know today.

    Many famous musicians played the instrument. The famous Italian violins Niccole Paganism played and wrote music for the guitar in the early 1800s. Franz Schubert used the guitar to write some of his famous works. In modern times Spanish guitarist Andres Segovia helped make the instrument extremely popular.

    In the 1930s, Les Paul began experimenting to make an electric guitar. He invented the solid-bodied electric guitar in 1946. The Gibson Guitar Company began producing its famous Les Paul Guitar in 1952. It became a powerful influence on popular music. The instrument has the same shape and the same six strings (弦) as the traditional guitar, but it sounds very different. Les Paul produced a series of extremely popular recordings that introduced the public to this music. Listen to this Les Paul recording. It was the fifth most popular song in the United States in 1952. It is called “Meet Mister Callaghan.”

The Cost of Higher Education

    Individuals (个人) should pay for their higher education.

    In general, a university education is of huge and direct benefit to the individual. Whether they are majoring in geography, geometry or any other subject, graduates earn more than non-graduates. Meanwhile, social mobility is ever more dependent on having a degree. However, only some people have it. So the individual, not the taxpayers should pay for it. There are pressing calls on the resources (资源) of the government. Using taxpayers' money to help small number of people to earn high incomes in the future is not one of them.

    Full government funding (资助) is not very good for universities. Adam Smith worked in a Scottish university whose teachers lived off student fees. He knew and looked down upon 18th-century Oxford, the grand university having much glory, where the academics lived comfortably off the income received from the government. Guaranteed salaries, Smith argued, were the enemy of hard work and when the academics were lazy and incompetent, the students grew similarly lazy in a gradual way.

    If students have to pay for their education, I guess they not only work harder, but also demand more from their teachers and have a better grasp of the subjects. And their teachers have to keep them satisfied. If that means taking teaching seriously, and giving less time to their own research interests, that is surely something to celebrate.

    Many people believe that higher education should be free because it is good for the economy (经济). Many graduates clearly do contribute to national wealth, but so do all the businesses that invest (投资) and create jobs. If you believe that the government should be generous enough to pay for higher education because graduates are economically productive, you should also believe that the government should pay part of business costs. Anyone promising to create jobs should receive a gift of capital（资金） from the government to invest.

    Therefore, it is the individual, not the government who should pay for their university education.

    We all are familiar with Android and iOS platforms as both are popular but are quite different when it comes to functionalities.

    If you are making a big move from Android to iPhone, then the first thing that counters your mind is how to get your data on the iPhone.

    Note: You need to turn on Wi-Fi on your Android & iPhone and connect them with the same network.

    So, let's get started and learn how to transfer data from Android to iPhone.

    Note: Please keep in mind that the steps might vary from device to device.

    Install (安装) the "Move to iOS" App on your Android device from the Google play store. This application is developed by Apple and available for free.

    Once you are done with installing the app, you need to grant permissions to the app. Now, follow on-screen instructions to proceed.

    Now, keep your Android aside and start your iPhone. Follow the on-screen instructions to set up your iPhone.

    The transfer might take a bit longer depending upon the size of the content.

    On your iPhone screen, you will see a screen saying," Continue setting up iPhone".

    You can continue setting up your Apple ID on your new iPhone. Once done, you will find all your data such as contacts, messages, bookmarks, pictures etc. on it.

    That's it, now you can dump your old Android phone and enjoy using your iPhone.

    Feeding birds is a popular way to watch wildlife. But experts say it might put wild birds at risk.

    Feeding birds is not necessary for their survival except in extreme weather conditions. Feeders(喂食器)can definitely help birds get through that kind of weather. But most birds eat insects and show little interest in bird feeders. For those birds, we can grow native plants in a natural environment. Birds which are fond of eating seeds will be more likely to come to feeders if there is some cover nearby. This lets them feed and then fly to protective areas, such as in trees.

    The most common mistake people make with their bird feeders is that they put feeders in places where birds are easily frightened by passers-by, risk being hurt by cats, or risk flying into windows.

    So set up a bird feeder at least one meter away from a window. That way, if a bird gets frightened, it won't get killed when it hits the glass. Owners of cats should keep them inside home so they can't hurt the birds.

    Some birds are more aggressive at feeders. They eat a lot and do not leave much food for other birds. A solution is to put the food in more than one place by using different kinds of seeds or fruits. This can also increase the number and diversity of birds in your neighborhood. But don't feed wild birds anything salty, like potato chips, or food that could choke them, like bread.

    Pay attention to food quality and freshness. Unprotected food left too long in feeders will turn moldy(发霉), which can kill wildlife.

    Another word of advice: Always provide a supply of clean water for birds, but use care when looking for the right birdbath. If the birdbaths are too deep for birds, putting a few large stones in the water can give the birds a place to sit.

There's a useful concept from psychology that helps explain why good people do things that harm the environment: the false consensus effect. That's where we overvalue how acceptable and prevalent（普遍的） our own behavior is in society. Put simply, if you're doing something （even if you secretly know you probably shouldn't）, you're more likely to think plenty of other people do it too. What's more, you likely overestimate how much other people think that behavior is broadly OK.

This bias（偏见） allows people to justify socially unacceptable or illegal behaviors. Researchers have observed the false consensus effect in drug use and illegal hunting. More recently, conservationists are beginning to reveal how this effect contributes to environmental damage.

In Australia, people who admitted to poaching（偷猎） thought it was much more prevalent in society than it really was, and had higher estimates than fishers who obeyed the law. They also believed others viewed poaching as socially acceptable; however, in reality, more than 90% of fishers held the opposite view. The false consensus effect has also shown up in studies examining support for nuclear energy and offshore wind farms.

Just as concepts from psychology can help explain some forms of environmental damage, so too can they help address it. For example, research shows people are more likely to litter in areas where there's already a-lot of trash scattered around; so making sure the ground around a bin is not covered in rubbish may help.

Factual information on how other people think and behave can be very powerful. Energy companies have substantially reduced energy consumption simply by showing people how their electricity use compares to their neighbors. Encouragingly, stimulating people's natural desire for status has also been successful in getting people to "go green to be seen", or to publicly buy eco-friendly products.

As the research evidence shows, social norms can be a powerful force in encouraging and popularizing environmentally friendly behaviors. Perhaps you can do your bit by sharing this article!
