While there are certainly many more varieties of English, American and British English are the two main varieties. Generally, it is agreed that no version is "correct", however, there are certainly preferences in use. The most important rule is to try to be consistent（一致） in your usage. If you decide to use American English, then be consistent in your spelling (i.e. "The color of the orange is also its flavour..." - color is American spelling and flavour is British). This is of course not always easy or possible. The following guide is meant to point out the principal differences between these two varieties of English.

　　In British English the present perfect is used to express an action that has occurred in the recent past that has an effect on the present moment. For example:

I've lost my key. Can you help me look for it?

In American English the following is also possible:

I lost my key. Can you help me look for it?

In British English the above would be considered incorrect. However, both forms are generally accepted in standard American English. Other differences involving the use of the present perfect in British English and the simple past in American English include already, just and yet.

British English:

I've already seen that film.

American English:

I've already seen that film. OR I already saw that film.

There are two forms to express possession in English: "Have" or "Have got".

Do you have a car?

Have you got a car?

While both forms are correct (and accepted in both British and American English), "have got" is generally the preferred form in British English while most speakers of American English only use "have".
