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-tired trackless trains, which are unrelated to other kinds of trams.
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 trams 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 such as buses led to decline of ...

Storms Kill At Least 11 Near Moscow; 60,000 Evacuated
At least 11 people have been killed after strong thunderstorms and high winds buffeted Moscow and surrounding areas on Monday.
Winds up to 70 mph were reported, and officials said most of the deaths were caused by falling trees.
60,000 people in Russia's Stavropol region are being evacuated due to the threat of flooding.
At least 11 people have been killed after strong thunderstorms and high winds buffeted Moscow and surrounding areas on Monday.
Winds gusted as high as 70 mph during the storm, which is rare for Moscow, said weather.com meteorologist Brian Donegan. Some hail was also reported along with torrential rain.
Russian officials told the Associated Press that most of the fatalities were caused by falling trees. According to the UK Guardian, 13 people have died as a result of the storms.
“Due to storm winds hitting Moscow, 50 people have asked for medical attention up to now,” a spokesperson for the City Hall’s health department told AFP, the UK Guardian reports. “Eleven were fatally injured.”
Two more deaths were reported when the investigative committee of the Moscow region said an 11-year-old girl and a 57-year-old man were killed, one by a falling tree and the other by a flying fence, the Guardian says.
Russian television stations showed metal fences, garages and even a construction crane toppled by winds around the capital, where about 3,500 trees were destroyed, the AP reports. The gusts damaged dozens of cars and disrupted train service and electricity supplies in some areas. Flights at Moscow's airports were delayed. A top emergency official said that 60,000 people in Russia's Stavropol region are being evacuated due to the threat of flooding.
The Moscow mayor, Sergei Sobyanin, expressed condolences for those who died, the UK Guardian reports. “Several hundred trees were felled,” he wrote on his official Twitter. “We are taking necessary measures to deal with the consequences.”
