你在日常谈话中使用的词语往往与标准的英文书面用语不同。虽然读者可以理解这些非正式用语的意思—gotta, gonna, wanna, kinda—你也不应该在写文章时使用这些词语。这里有两个使用非标准词的例句：
I told her I gotta go to school now. I told her I have got to go to school now.
Do you wanna go to college? Do you want to go to college?
即使你能明白作者的意思，gotta和wanna 这样的词在标准英语中是不存在的。
The words you use in everyday conversation are often different from the words you use in standard written English. While a reader might understand these informal words — gotta, gonna, wanna, kinda — you should not write them in an essay. Here are two examples of nonwords used in sentences:
I told her I gotta go to school now. I told her I have got to go to school now.
Do you wanna go to college? Do you want to go to college?
Even though you can understand what the writer means, the words gotta and wanna do not exist in Standard English.
