听力原文: In the early 1960s a new sound was heard, very different from anything, which had so far come from the American side of the Atlantic. This was the Liverpool, or northwestern "beat". Situated on the river Mersey in the northeastern corner of the industrial Black Country, Liverpool was not a place that anyone visited for fun. Until the 1960s it was known only as one of Britain's largest ports. Then, overnight, it became world famous as the birthplace of the new pop culture which, in a few years, swept across Britain and America, and most countries of the Western world.
The people responsible for the pop revolution were four Liverpool boys who called themselves The Beatles. They played in small clubs in the back streets of the city. Unlike the famous solo stars who had their songs written for them, The Beatles wrote their own words and music.
Some pop groups, in particular the Rolling Stones, did more than just entertain. They wrote words that were deliberately intended to shock. They represented the anger and bitterness of youth struggling for freedom against authority.
The Beatles finally won the affect/on and admiration of people of all ages and social backgrounds. Their songs became more serious. They wrote not only of love, but also of death and old age and poverty and daily life. They were respected by many intellectuals and by some serious musicians. Largely thanks to The Beatles, pop music has grown into an immense and profitable industry.

A.It is located on the river Mersey.
B.It is the birthplace of lots of musicians and intellectuals.
C.It is one of Britain's largest ports.
D.It is the birthplace of the new pop culture.
