業精於勤，事立於豫

21. Be sure to come here on time without failure. (務必準時到達。)

更正：fail 

[Note] be sure to 之後加用 without fail 感受上稍嫌 redundant(多餘的)；但爲了加強語氣，還是可以使用。

22. The profession of my father's is an English teacher. (我父親是英語老師。)

更正：My father

[Note] teacher 的意思是 "a person who gives lessons or classes"，

profession 的意思是 "job that requires special education and training"，兩者性質迥異。

23. Many father's friends came to the meeting. (許多父親的朋友列席會議。)

更正：Many of my father's friends / Many friends of my father's / Many friends of my father / My father's many friends.

[Note] 除了第四句，其他前三句在語法上均可通用，其意思是 "My father has many friends and a lot of them (but not all) came to the meeting."，而第四句的表現方式在語法上是正確的，只有意義稍有不同，是指 "My father has many friends and all of them came to the meeting"。

24. They had a really nice play in Yankee Stadium last night. (昨晚他們在洋基棒球場上表現得很優越。)

更正：game

[Note] play的意思是指 "something that is done for fun or pleasure" ，

game的意思是 "a contest in which the players must follow specific rules"。

25. Kick your bad custom. (改掉你的壞習慣。)

更正：habits/habit

[Note] custom 是指某一國家或社會長期延續下來的傳統習俗，

habit 是指個人無意中反蹈覆轍的習慣。

kick 意思是 "discontinue"、" stop" 。

26. He put up with much hardiness. (他忍受萬般困難。)

更正：hardship

[Note] hardiness 的意思是 "physical endurance(體能耐力; 體能極限)"，

hardship是 "the condition of difficulty, pain, or suffering, such as poverty or illness"

27. The head office is in Tokyo. (總公司設於東京。)

更正：headquarters / main office

28. John showed us an action of heroism. (約翰顯示了英雄式的行爲。)

更正：a heroic act

[Note] act 常使用於個人的行爲，

action 則使用於抽象或團體性的行爲。

29. I still keep some library books at house. (圖書館的書還有幾本放在家裏。)

更正：home

[Note] at house 不合語法。

30. Check the passports of all the emigrants. (審核所有移民的護照。)
