Grammar – You’re a-f-r-a-i-d of grammar, but it’s really your friend! Grammar is the form in which words are expressed and understood. I ate cornflakes this morning, but I didn’t eat waffles. In the past simple negative, your verb becomes infinitive, because everybody understands from “did” that you’re talking about this morning, yesterday, last week, last month or last year.
English is indispensable for your education, careers and self-edification. Learning keeps you young. The English you speak and write tomorrow is the English you study today.
