(单选题) As days _________, a deep friendship began to develop between them. (本题2.5分)A. went byB. went inC. went passD. went out

本题考查动词短语的固定搭配，核心在于识别表示“时间流逝”的正确表达。关键点在于：

1. "go by" 是固定短语，意为“经过、流逝”，常用于时间相关语境；
2. 其他选项中的搭配（如 "go in"、"go pass"、"go out"）均不符合题意；
3. 时态需与主句中的 "began" 保持一致，使用过去式 "went by"。

选项分析

A. went by

"Go by" 是固定短语，表示“时间经过”，如 "Days went by quickly"（日子过得很快）。此处与主句时态一致，正确。

B. went in

"Go in" 表示“进入”，如 "She went in the room"，与时间流逝无关，排除。

C. went pass

"Go pass" 不是固定搭配。正确表达应为 "pass" 单独使用（如 "Days passed"），或 "go by"，排除。

D. went out

"Go out" 表示“出去”或“熄灭”，如 "The light went out"，与题意无关，排除。
