Question

【題目】At the age of 14, Father had to leave school and start working. There would be no one to support the family _______ he not worked.
A.did
B.has
C.had
D.was

Answer 1

【答案】C
【解析】考查動詞時態。句意：14歲時，父親不得不離開學校，開始工作。要是他不工作的話，就沒有人來養活這個家庭了。此處是if引導的非真實條件句，與過去事實相反，當把if省略時則把助動詞had/should情態動詞were提到主語前面。故選C。
