How many types of universities are there in Britain?
最好能用双语解答,并给出一些例子~
我大概知道有五类,第一种好像是OLD UNIVERSITIES,指的是牛津和剑桥,第二种是苏格兰四大学（THE FOUR SCOTTISH UNIVERSITIES?）,后面的就更不太清楚了,

UK universities can be classified into 5 main categories:
Ancient universities - universities founded before the 19th century
Red Brick universities - universities founded in the 19th and early 20th centuries.
New Universities - two categories of institutions have been given this label:
those created in the 1960s less often called Plate Glass Universities,which were known as "New Universities" when first created,but which are now more commonly considered a sub-section of the "Old Universities" which existed prior to the 1992 changes which allowed Polytechnics to become Universities,and
those created in or after 1992 often called Post-1992 universities,from polytechnics and colleges of Higher Education,which are the Universities most commonly referred to as "New Universities" in the present day.
The Open University,founded in 1968 is Britain's sole mainly distance-learning University.
The University of London and the University of Wales have since their inception been federal universities.That is,a governing body with over all responsibility for the maintenance of standards at the constituent colleges.Recently,however,there has been considerable pressure from the larger colleges to become completely autonomous institutions.An example of this would be the secession of Imperial College London to become independent and autonomous from the federal University of London,or Cardiff University leaving the University of Wales.
The University of Buckingham is the sole private university of the UK.
