　　參考答案：

　　1.正確答案：C答案解析：像這類題考查單詞的掌握，四個(gè)詞意思不一樣，就看哪一個(gè)放在句中邏輯上、語法上是正確的。這里come to the conclusion是一個(gè)固定詞組，意指“得出結(jié)論”。

　　2.正確答案：A答案解析：本題考查的是虛擬語氣的用法，表示的是與過去相反的情況，要用過去完成時(shí)，答案為A.

　　3.正確答案：A答案解析：本題考查的是固定搭配的用法。have no choice but to do sth.表示“別無選擇只能做某事”。

　　4.正確答案：B答案解析：account for表示：是……的原因/理由。

　　5.正確答案：C答案解析：本題考查的是if引導(dǎo)的虛擬條件句，省略了if要把had提前。
