常和 already（已经）yet（已经；还）just（刚刚）ever（曾经）never（从不）等连用。
标志词1：already1. 核心含义：已经，强调动作已经完成，带有“提前完成”的意味2. 适配句式：肯定句（偶尔用于疑问句，表惊讶，本单元不侧重）3. 固定位置：句中，位于 have/has 之后，动词过去分词之前4. 例句（贴合单元）：I have already brrwed the bk frm the library.5. 易错点：不可用于否定句/疑问句（否定/疑问用yet）
标志词2：yet1. 核心含义：还；仍，强调动作未完成，多用于否定/疑问结尾2. 适配句式：否定句、一般疑问句（不用于肯定句）3. 固定位置：句末（否定句、疑问句的末尾）4. 例句（贴合单元）： 疑问句：Have yu chsen a bk fr yur reprt yet? 否定句：She hasn’t finished reading the bk yet.
标志词3：never1. 核心含义：从未，强调动作从过去到现在从未发生过2. 适配句式：否定句（本身含否定意味，无需再加nt）3. 固定位置：句中，位于 have/has 之后，动词过去分词之前4. 例句（贴合单元）：He has never heard f this famus authr.5. 易错点：避免双重否定（如：has never nt heard 错误）

标志词5：just（详细讲解）1. 核心含义：刚刚，强调动作刚完成不久（动作发生在近期）2. 适配句式：肯定句（偶尔用于否定句）3. 固定位置：句中，位于 have/has 之后，动词过去分词之前4. 例句（贴合单元）：I have just finished my bk reprt.5. 易错点：与already区分，just侧重“刚完成”，already侧重“已完成”
