Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
A tram (in North America streetcar or trolley) is a rail vehicle which runs on tramway tracks along public urban streets; some include segments of segregated right-of-way. The lines or networks operated by tramcars are called tramways. Historically the term electric street railways was also used in the United States. In the United States, the term tram has sometimes been used for rubber-tyred trackless trains, which are not related to the other vehicles covered in this article.
Tram vehicles are usually lighter and shorter than main line and rapid transit trains. Today, most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases by a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city streets, and diesel in more rural environments. Occasionally, trams also carry freight. 

Trams are now commonly included in the wider term "light rail", which also includes grade-separated systems. Some trams, known as tram-trains, may have segments that run on mainline railway tracks, similar to interurban systems. The differences between these modes of rail transport are often indistinct, and a given system may combine multiple features.
One of the advantages over earlier forms of transit was the low rolling resistance of metal wheels on steel rails, allowing the animals to haul a greater load for a given effort. Problems included the fact that any given animal could only work so many hours on a given day, had to be housed, groomed, fed and cared for day in and day out, and produced prodigious amounts of manure, which the streetcar company was charged with disposing of. Electric trams largely replaced animal power in the late 19th and early 20th century. Improvements in other forms of road transport  ...
