中學生英語學習常見錯誤一覽表4
join ［誤］ did you attend the football club?
［正］ did you join the football club?
［析］ join經常用于參加某個團體、政黨，并作為其中的一個成員；attend則重點強調出會議、到場，而不一定進行具體活動，如： did you attend the meeting yesterday?而take part in則強調參與某些具體活動或運動，如： i take part in the football game.
just
［誤］ i have finished my work just now.
［正］ i finished my work just now.
［析］ just now意義"剛才"，所以句中的謂語動詞要用過去式。
［誤］ just i won the game.
［正］ i just won the game.
［析］ just單獨使用時不應放在句首，而應放于① be動詞之后，如： he is just a student.② 名詞與一般動詞之間。③ 用在第一助動詞之后，如： i have just returned home. 但just與其他詞組成詞組時，如just now, just then, 則可用于句首和句尾。如： just then he saw the bus coming.
just justly
just常用于三種含意： ① 恰好，如： it's just five o'clock. ② 僅僅，相當于only, 如： i have just enough money to buy a dictionary. ③ 不久前，如： i just missed my old friend; he left a few minutes ago. 而justly其意為"公正的"，如： he was justly punished for his crimes.
k
keep
［誤］ she was keeping something to her father.
［正］ she was keeping something from her father.
［析］ "對某人隱瞞某事"要用"keep something from somebody"句型。
［誤］ he kept to repeat the word again and again.
［正］ he kept repeating the word again and again.
［析］ keep doing something為連續不斷地做某事。有時可以與keep on doing something互換。它們的區別在于keep doing something意為該動作一直不停地在進行中，如： when the train started, she kept waving her hand. 而keep on doing something則表示該動作可能停停頓頓但卻一直在進行中，如： he kept on making the same mistakes in grammar.
［誤］ we must keep up the times.
［正］ we must keep up with the times.
［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 (key) 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sort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.
