本影片所學文法為附加問句-Tag Questions，透過Mike和Linda之間的對話帶入課程，說明附加問句的規則。首先，第一個規則為前句如果是肯定句，則後方的附加問句為否定句，例如Tomorrow is Saturday, isn't it?；假如前句是否定句，則後方的附加問句為肯定句，例如Tomorrow isn't Saturday, is it?。第二個規則為在主要的句子中如果有be動詞，則會由be動詞領導後方的附加問句，例如Linda is beautiful, isn't she?／You aren't a teacher, are you?。第三個規則為在主要的句子中如果有助動詞(auxiliary verb)，則會由助動詞領導後方的附加問句，例如Linda can dance, can't she?／You won't come with us, will you?／Jack has gone to Japan, hasn't he?。第四個規則為主要的句子中如果是動詞，則需要使用適當的助動詞領導後方的附加問句，例如You like English, don't you?／She likes English, doesn't she?／She liked English, didn't she?。
