题目性质：自编仿真题——题目、材料、选项、数据与情境均为按课程标准与联招常见考点独立编写的原创仿真题，非真题原文，未取自任何题库、教辅或试卷；解析与采分点为教研整理，非官方评分标准。
一、考点定位与做题顺序
连接副词设空，第一步永远不是看选项，而是把空前一句与空后一句各写成一句中文，问：后句是推翻前句、承接结果、补一层，还是换了一个做法？关系定下来，选项范围立刻缩到一两个。
第二步查形式：however 与 nevertheless 作句间副词时后面常有逗号，也可插在句中；therefore / thus / consequently 表结果，moreover / furthermore / besides 表追加，instead / rather 表「不…而是…」，otherwise 表「否则」，自带条件意味。第三步才排除近义干扰。下面短文为自编示意文本，馆名、数据与人物均为虚构。
二、逐题精讲
题1
题1 八空完形（每空四选一）
自编短文：A small town library once lent books only across a desk. Readers had to ask a clerk, and the clerk fetched each title from a closed room. The system worked, (1)____ it was slow: on a busy Saturday a single request could take twelve minutes. In 2024 the librarians opened the shelves to readers. They expected the change to cut waiting time sharply; (2)____, the average fell only from twelve to nine minutes. (3)____, the number of books borrowed did rise — by about a fifth over the next six months.
The librarians looked more closely. Readers now spent longer choosing, (4)____ each individual request itself was faster. (5)____, many of them browsed several shelves before settling on one book. The desk was no longer a bottleneck; (6)____, the aisle had become one. So they widened the aisles and added signs. (7)____, waiting time dropped to four minutes. (8)____ they had kept the old desk, none of this browsing would have appeared at all.
(1) A. therefore B. but C. moreover D. instead
(2) A. however B. thus C. besides D. otherwise
(3) A. Nevertheless B. Consequently C. Otherwise D. Instead
(4) A. because B. so C. although D. unless
(5) A. In fact B. As a result C. For example D. In contrast
(6) A. instead B. therefore C. moreover D. nevertheless
(7) A. However B. In addition C. As a result D. Otherwise
(8) A. If B. Unless C. Although D. Since
解析
(1) B (but)。 前句「系统能运转」与后句「它很慢」是同一对象的转折让步，且空后紧跟冒号举例，需并列连词 but 直接连接；therefore／moreover 方向反了，instead 要求「不做前者而做后者」，此处没有替换动作。(2) A (however)。 前句「预期大幅缩短」与后句「只从 12 降到 9 分钟」是预期与结果的反差，用转折；且空后有逗号，正是 however 的典型位置。注意 thus 会把「只降一点」写成预期的结果，逻辑不通。
(3) A (Nevertheless)。 前句刚说等待时间降得不多，后句却说借阅量涨了约两成——尽管前者不理想，后者仍成立，是让步转折；句首大写＋逗号，选 Nevertheless。Consequently 会把涨借阅量说成「降得少」的结果，Instead 要求替换，Otherwise 自带「否则」条件，均不合。
(4) C (although)。 「读者花在挑选上的时间更长」与「单次取书本身更快」并存且方向相反，用让步状语从句 although；because／so 强加因果，unless 是条件。
(5) A (In fact)。 后句「很多人要逛好几个书架才定一本」是对前句「挑选时间更长」的具体化／确认，用 In fact。For example 看似可通，但这里不是举例而是把原因坐实；As a result 颠倒因果；In contrast 无对照双方。
(6) A (instead)。 「柜台不再是瓶颈；过道倒成了瓶颈」是典型的位置替换，用 instead（前有分号、后有逗号）。therefore 会把「过道成瓶颈」说成「柜台不堵」的结果，虽可勉强读懂，但丢掉了「换了个地方」这层对照。
(7) C (As a result)。 「加宽过道、加标识」→「等待降到 4 分钟」是措施与结果；However 方向反，In addition 只是追加，Otherwise 是条件。
(8) A (If)。 「____ 他们保留旧柜台，这些浏览行为根本不会出现」是与过去事实相反的非真实条件，且主句用 would have appeared，须 If 配过去完成；Unless 等于 if not，放进去意思反了；Although／Since 不引导这类虚拟条件。
回读验：把八个答案代回，全篇两条线自洽——「等待时间 12→9→4 分钟」与「借阅量涨约两成／浏览行为出现」；转折词全部落在预期落空、局部变好、瓶颈易位三处，因果词只落在措施→结果一处，没有一处混用。
答案 (1) B (2) A (3) A (4) C (5) A (6) A (7) C (8) A
采分点 每空 1 分；能写出「前后两句的逻辑关系」判据每空另计 0.5；第(2)(3)空说明逗号与句首大写的位置依据 1 分；第(8)空指出 would have appeared 与 If 的虚拟条件呼应 1 分；整体回读说明两条线自洽 1 分。
易错点 见词就选：看到「降了」就选 therefore、看到「涨了」就选 consequently，忽略预期与结果的反差；把 however 与 but 混用（but 是并列连词，不接逗号独立成句）；第(6)空选 therefore，漏掉「瓶颈换位置」的替换意味；第(8)空选 Unless，把非真实条件读反。
题2
题2 位置与标点改写、近义辨析
(1) 把「They expected the change to cut waiting time sharply; however, the average fell only from twelve to nine minutes.」中的 however 改放到句中（不改变意思），写出改写句并说明标点变化。(2) 辨析三组近义表达各适用于什么逻辑关系：however / nevertheless；therefore / as a result；instead / rather。各造一个基于本篇情境的短句。
解析
(1) 可写：The average, however, fell only from twelve to nine minutes. 或 The average fell only from twelve to nine minutes, however.（较口语、书面少用）。标点变化：however 从句首副词＋逗号变为插入语，前后各用逗号；原句的分号在改写后不再需要，因为已拆成独立句。注意 however 不能像 but 那样直接连接两个并列分句（写成「…sharply, however the average…」不合书面规范），这是位置题最常考的一点。(2) ① however / nevertheless：转折或让步，承认前句成立再指出后句不受其影响；nevertheless 让步意味更重（「尽管如此」）。例：The wait fell only slightly; nevertheless, borrowing rose by a fifth.
② therefore / as a result：结果；therefore 偏推理结论，as a result 偏由具体措施引出的可观察结果。例：They widened the aisles; as a result, waiting time dropped to four minutes.
③ instead / rather：替换／取舍，「不做 A 而做 B」；rather 常与 than 或 would 搭配表偏好。例：The desk was no longer the bottleneck; instead, the aisle was.／Readers chose to browse rather than queue at the desk.
辨析要点：三组的分界是「后句是否推翻／承接／替换前句」，不是语气强弱。把 instead 当 however 用，会凭空多出一层「换做法」的意思；把 as a result 当 nevertheless 用，则把让步读成因果。
答案 (1) The average, however, fell only from twelve to nine minutes.（插入语前后逗号，原分号取消）。(2) ① 转折让步 ② 结果 ③ 替换取舍；造句见上。
采分点 改写句语序正确 1 分；说明 however 作插入语前后逗号、分号取消 1 分；指出 however 不能像 but 直接连接分句 1 分；三组关系判定各 1 分；三个造句各 1 分；点明「分界在逻辑关系而非语气强弱」1 分。
易错点 把 however 移到句中却只加一个逗号；改写后仍保留分号，造成「分号＋逗号」冗余；把 nevertheless 讲成「因此」；把 instead 与 however 混为一谈；造句脱离本篇情境，看不出关系类型。
三、规律小结与对照表
| 表达 | 逻辑关系 | 典型位置与标点 | 自编示例句 | 易混项 |
|---|---|---|---|---|
| but | 并列转折 | 直接连接分句，不加独立逗号 | The system worked, but it was slow. | however（副词，不能直连） |
| however | 句间转折 | 句首＋逗号；或插入语前后逗号 | …; however, the average fell only… | but / nevertheless |
| nevertheless | 让步转折 | 句首＋逗号 | Nevertheless, borrowing did rise. | consequently |
| therefore / thus | 推理结果 | 句首或句中，多不加逗号 | …; therefore the plan was revised. | as a result |
| as a result | 措施→结果 | 句首＋逗号 | As a result, waiting time dropped… | in addition |
| moreover / besides | 追加一层 | 句首＋逗号 | Moreover, the count rose. | however |
| instead | 替换／瓶颈易位 | 分号＋instead，常带逗号 | The desk was not; instead, the aisle was. | therefore |
| otherwise | 「否则」隐含条件 | 句首＋逗号 | Otherwise the old queue would remain. | unless |
| If + had done | 非真实条件 | 从句 If，主句 would have done | If they had kept the desk… | Unless / Although |
这类空的判分点从来不在「认不认识这个词」，而在前后两句到底是什么关系，以及这个词该站在句子的哪个位置、带什么标点。先写两句中文定关系，再验形式，最后才排除近义干扰；回读一遍，若转折词落在了纯因果处，或因果词落在了预期落空处，八成是选反了。本篇馆名、12→9→4 分钟、借阅量约两成等均为自编示意，不代表真实统计。
四、自测清单
- □ 每空先把前后句各译成一句中文，写下「推翻／结果／追加／替换／条件」；
- □ 句首连接副词检查「大写＋逗号」，插入语检查前后双逗号；
- □ however 不直接连接两个分句，那是 but 的用法；
- □ 见到 would have done 回头找 If + had done 的虚拟条件；
- □ 分号后出现 instead，先问「是不是换了位置或换了做法」；
- □ 八个答案代回通读，检查两条数据线没有自相矛盾。
