題目性質：自編仿真題——題目、材料、選項、數據與情境均為按課程標準與聯招常見考點獨立編寫的原創仿真題，非真題原文，未取自任何題庫、教輔或試卷；解析與採分點為教研整理，非官方評分標準。
一、考點定位與做題順序
連接副詞設空，第一步永遠不是看選項，而是把空前一句與空後一句各寫成一句中文，問：後句是推翻前句、承接結果、補一層，還是換了一個做法？關係定下來，選項範圍立刻縮到一兩個。
第二步查形式：however 與 nevertheless 作句間副詞時後面常有逗號，也可插在句中；therefore / thus / consequently 表結果，moreover / furthermore / besides 表追加，instead / rather 表「不…而是…」，otherwise 表「否則」，自帶條件意味。第三步才排除近義干擾。下面短文為自編示意文本，館名、數據與人物均為虛構。
二、逐題精講
題1
題1 八空完形（每空四選一）
自編短文：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「系統能運轉」與後句「它很慢」是同一對象的轉折讓步，且空後緊跟冒號舉例，需並列連詞 but 直接連接；therefore／moreover 方向反了，instead 要求「不做前者而做後者」，此處沒有替換動作。(2) A (however)。 前句「預期大幅縮短」與後句「只從 12 降到 9 分鐘」是預期與結果的反差，用轉折；且空後有逗號，正是 however 的典型位置。注意 thus 會把「只降一點」寫成預期的結果，邏輯不通。
(3) A (Nevertheless)。 前句剛說等待時間降得不多，後句卻說借閱量漲了約兩成——儘管前者不理想，後者仍成立，是讓步轉折；句首大寫＋逗號，選 Nevertheless。Consequently 會把漲借閱量說成「降得少」的結果，Instead 要求替換，Otherwise 自帶「否則」條件，均不合。
(4) C (although)。 「讀者花在挑選上的時間更長」與「單次取書本身更快」並存且方向相反，用讓步狀語從句 although；because／so 強加因果，unless 是條件。
(5) A (In fact)。 後句「很多人要逛好幾個書架才定一本」是對前句「挑選時間更長」的具體化／確認，用 In fact。For example 看似可通，但這裡不是舉例而是把原因坐實；As a result 顛倒因果；In contrast 無對照雙方。
(6) A (instead)。 「櫃檯不再是瓶頸；過道倒成了瓶頸」是典型的位置替換，用 instead（前有分號、後有逗號）。therefore 會把「過道成瓶頸」說成「櫃檯不堵」的結果，雖可勉強讀懂，但丟掉了「換了個地方」這層對照。
(7) C (As a result)。 「加寬過道、加標識」→「等待降到 4 分鐘」是措施與結果；However 方向反，In addition 只是追加，Otherwise 是條件。
(8) A (If)。 「____ 他們保留舊櫃檯，這些瀏覽行為根本不會出現」是與過去事實相反的非真實條件，且主句用 would have appeared，須 If 配過去完成；Unless 等於 if not，放進去意思反了；Although／Since 不引導這類虛擬條件。
回讀驗：把八個答案代回，全篇兩條線自洽——「等待時間 12→9→4 分鐘」與「借閱量漲約兩成／瀏覽行為出現」；轉折詞全部落在預期落空、局部變好、瓶頸易位三處，因果詞只落在措施→結果一處，沒有一處混用。
答案 (1) B (2) A (3) A (4) C (5) A (6) A (7) C (8) A
採分點 每空 1 分；能寫出「前後兩句的邏輯關係」判據每空另計 0.5；第(2)(3)空說明逗號與句首大寫的位置依據 1 分；第(8)空指出 would have appeared 與 If 的虛擬條件呼應 1 分；整體回讀說明兩條線自洽 1 分。
易錯點 見詞就選：看到「降了」就選 therefore、看到「漲了」就選 consequently，忽略預期與結果的反差；把 however 與 but 混用（but 是並列連詞，不接逗號獨立成句）；第(6)空選 therefore，漏掉「瓶頸換位置」的替換意味；第(8)空選 Unless，把非真實條件讀反。
題2
題2 位置與標點改寫、近義辨析
(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（不改變意思），寫出改寫句並說明標點變化。(2) 辨析三組近義表達各適用於什麼邏輯關係：however / nevertheless；therefore / as a result；instead / rather。各造一個基於本篇情境的短句。
解析
(1) 可寫：The average, however, fell only from twelve to nine minutes. 或 The average fell only from twelve to nine minutes, however.（較口語、書面少用）。標點變化：however 從句首副詞＋逗號變為插入語，前後各用逗號；原句的分號在改寫後不再需要，因為已拆成獨立句。注意 however 不能像 but 那樣直接連接兩個並列分句（寫成「…sharply, however the average…」不合書面規範），這是位置題最常考的一點。(2) ① however / nevertheless：轉折或讓步，承認前句成立再指出後句不受其影響；nevertheless 讓步意味更重（「儘管如此」）。例：The wait fell only slightly; nevertheless, borrowing rose by a fifth.
② therefore / as a result：結果；therefore 偏推理結論，as a result 偏由具體措施引出的可觀察結果。例：They widened the aisles; as a result, waiting time dropped to four minutes.
③ instead / rather：替換／取捨，「不做 A 而做 B」；rather 常與 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.
辨析要點：三組的分界是「後句是否推翻／承接／替換前句」，不是語氣強弱。把 instead 當 however 用，會憑空多出一層「換做法」的意思；把 as a result 當 nevertheless 用，則把讓步讀成因果。
答案 (1) The average, however, fell only from twelve to nine minutes.（插入語前後逗號，原分號取消）。(2) ① 轉折讓步 ② 結果 ③ 替換取捨；造句見上。
採分點 改寫句語序正確 1 分；說明 however 作插入語前後逗號、分號取消 1 分；指出 however 不能像 but 直接連接分句 1 分；三組關係判定各 1 分；三個造句各 1 分；點明「分界在邏輯關係而非語氣強弱」1 分。
易錯點 把 however 移到句中卻只加一個逗號；改寫後仍保留分號，造成「分號＋逗號」冗餘；把 nevertheless 講成「因此」；把 instead 與 however 混為一談；造句脫離本篇情境，看不出關係類型。
三、規律小結與對照表
| 表達 | 邏輯關係 | 典型位置與標點 | 自編示例句 | 易混項 |
|---|---|---|---|---|
| but | 並列轉折 | 直接連接分句，不加獨立逗號 | The system worked, but it was slow. | however（副詞，不能直連） |
| however | 句間轉折 | 句首＋逗號；或插入語前後逗號 | …; however, the average fell only… | but / nevertheless |
| nevertheless | 讓步轉折 | 句首＋逗號 | Nevertheless, borrowing did rise. | consequently |
| therefore / thus | 推理結果 | 句首或句中，多不加逗號 | …; therefore the plan was revised. | as a result |
| as a result | 措施→結果 | 句首＋逗號 | As a result, waiting time dropped… | in addition |
| moreover / besides | 追加一層 | 句首＋逗號 | Moreover, the count rose. | however |
| instead | 替換／瓶頸易位 | 分號＋instead，常帶逗號 | The desk was not; instead, the aisle was. | therefore |
| otherwise | 「否則」隱含條件 | 句首＋逗號 | Otherwise the old queue would remain. | unless |
| If + had done | 非真實條件 | 從句 If，主句 would have done | If they had kept the desk… | Unless / Although |
這類空的判分點從來不在「認不認識這個詞」，而在前後兩句到底是什麼關係，以及這個詞該站在句子的哪個位置、帶什麼標點。先寫兩句中文定關係，再驗形式，最後才排除近義干擾；回讀一遍，若轉折詞落在了純因果處，或因果詞落在了預期落空處，八成是選反了。本篇館名、12→9→4 分鐘、借閱量約兩成等均為自編示意，不代表真實統計。
四、自測清單
- □ 每空先把前後句各譯成一句中文，寫下「推翻／結果／追加／替換／條件」；
- □ 句首連接副詞檢查「大寫＋逗號」，插入語檢查前後雙逗號；
- □ however 不直接連接兩個分句，那是 but 的用法；
- □ 見到 would have done 回頭找 If + had done 的虛擬條件；
- □ 分號後出現 instead，先問「是不是換了位置或換了做法」；
- □ 八個答案代回通讀，檢查兩條數據線沒有自相矛盾。
