different from Modern English. If we do not study old English, we can't understand it. Some of the words

are the same, but many are not used now. The story of the English language begins some time after the year

400 AD. At this time, some people came to England from North-west Europe. There were many groups of

people. They were called Angles (盎格鲁人), Saxons (撒克逊人) and Jutes (朱特人), whose language, old
