2019中考英語考前錯題本 （I,J,K字母篇）
［析］ 這句話意為"我們必須趕上時代"，keep up with是"趕上"之意，而keep up則是"堅持下去"的意思，如： keep it up, don't stop now!
key
［誤］ i lost the key of the door.
［正］ i lost the key to the door.
［析］ 英語中講某某的東西一般要用of，而key, entrance, answer則多用to，如："門的鑰匙"為key to the door, "高速公路入口"為entrance to the highway, "問題的答案"為the answer (k ey) to the question.
kind
［誤］ this kind of books are not good.
［正］ this kind of books is not good.
［析］ kind在這種句式中應作為主語，如果講those kinds of books are very good. 則是正確的。
kind sort type
kind和sor t為同義詞，意為"種類"，而type則為"型號"，如： what type of this car do you want?(你想要這種車的什么型號?)
knock
［誤］ someone was knocking the door.
［正］ someone was knocking at the door.
［析］ knock 雖可以作及物動詞，如： the car knocked a hole in the fence. 但作"敲門"講一定要用作不及物動詞： knock at (on) the door.
know
［誤］ i want to know to play this game.
［正］ i want to know how to play this game.
［析］ 要注意英語中在不定式前加疑問代詞或疑問副詞的用法。如：i want to know how to do it / what to do / when to do it / where to go.
know know of
i know hi m.為"我很了解他。"而i know of hi m. 則為"我聽說過他。"同樣的用法還有hear和hear of這一詞組。
