英式英语：

　　(1) I have lost my mobile phone. Have you seen it?

　　(2) I have just finished my homework.

　　美式英语：

　　(1) I lost my mobile phone. Did you see it?

　　(2) I just finished my homework.

　　英语和美语在句法上也有一些差别。当表达“去做某事”的时候，除了可以说go to do something，英式英语常用go and do something，而美式英语常用go do something，举个例子：

　　(1) I have to go and pick up my friends at the airport. (英)

　　(2) I have to go pick up my friends at the airport. (美)

　　(3) I have to go to pick up my friends at the airport. (英/美)

　　这一用法也适用于come，英式英语中用come and do something，美式英语中用come do something，比如：

　　(1) I want you to come and visit me. (英)

　　(2) I want you to come visit me. (美)

　　(3) I want you to come to visit me. (英/美)

　　英式英语和美式英语虽然存在一些差别，但两者之间无所谓谁更地道，只要能用正确就行。平时使用要注意两者之间的用词和拼写差异，在写作的时候应该保持前后一致，不要两种英语混用。
