British English and American English are almost the same.  

The first difference between British and American English is in vocabulary. Almost all of the words used in British English and American English are exactly the same.  For example, Americans would say "apartment", but the British would say "flat" to talk about the place where they live. In addition to some common words, many idiomatic (惯用的) expressions are different. In England people might say "I'll ring you up tonight", but in the US, people might say "I'll call you up tonight".

The second difference between British and American English is in pronunciation. The main difference in pronunciation lies in the vowels. But most of the time, the British and Americans do understand each other's pronunciation because most of the sounds of the two dialects are the same.

The third difference is very small.  A few types of words are spelled differently in British and American English. The most common example is in a word like "center". In British English, this word would be spelled C-E-N-T-R-E, while in American English the same word would be spelled C-E-N-T-E-R.

 The British may say "Have you got …?" while Americans prefer "Do you have …?" An American might say "my friend just arrived", but a British would say "my friend has just arrived".

A. This is the difference in spelling.

B. There are a few differences in grammar, too.

G. Sometimes, Americans and the British don't understand each other's pronunciation.
