1. 本題答案是B。
由and連接的兩個單數(shù)名詞作主語時，一般用復(fù)數(shù)形式，但and所連接的并列主語是同一個人，事物，或概念時，謂語動詞用單數(shù)。這兩種情況區(qū)分如下：a/the+單數(shù)名詞+and+單數(shù)名詞，指的是同一個人或物；a/the+單數(shù)名詞+and+ a/the+單數(shù)名詞，指兩個人或物。故答案為B
。
2. 本題答案是B。
第一個remaining用作形容詞，作“剩下的”解；第二個remaining to be settled是-ing形式短語作定語。故答案為B。

3. 本題答案是D
must后的反義疑問句一般與must后保持一致，但該句中有明確的過去時間狀語 two days ago，必須要與two days ago保持一致，因此反問語氣用過去式，故答案為D。
