English grammar is very complicated because unlike Chinese, English has many verb tenses. Even stranger than verb tenses, English grammar contains something confusing. For example, I can't remember how many times My middle school teacher tried to "force" the differences between habits on us. Sometimes he would go on explaining for about 20 minutes. He even Summarize these differences by listing three or four main points for us to remember. However, they will never stay in my mind. I can't remember how many times I got the sentence "used to" or "be used to" wrong on the test. I'm really confused by these two phrases. I'll never be able to figure it out In short, I am allergic to learning English grammar.
