## 学习目标

1. 还原否定倒装、强调结构、比较省略及嵌套从句，不改变逻辑范围。
2. 在复杂句中保留推测、限制和条件，写出准确中文释义。

3. 在本课主题中理解新增词块的语境用法，并把其中相关词项迁移到新的完整句子。

## 核心讲解

从四级向六级提高，不是把每个短词换成长词，而是增加信息密度、抽象关系与论证限制。本课程在这一层加入嵌套结构、谨慎论断和多个解释的比较；不声称真实考试每句必然比四级长。

**Only after the team checked the records did it realise that the apparent increase reflected a change in reporting.** Only+状语放句首，主句部分倒装did it realise；that从句仍为陈述语序。还原The team realised…only after…。“直到核对后才意识到”，不能漏only。

**Not until the costs were included did the proposal appear less attractive.** 还原The proposal did not appear less attractive until the costs were included。这里did后appear原形；不要写did appeared。倒装发生在主句，不在until从句。

**What matters is not whether the tool is new, but whether it helps users complete a task.** What引导主语从句，相当于the thing that matters；两个whether从句是并列的表语内容。not…but…否定“新不新是关键”，肯定“是否有助完成任务才关键”。

**The policy, if applied without exceptions, could disadvantage people whose schedules are irregular.** if applied=if it is applied；省略前提是主语可从policy恢复。could是可能，不是已证实。whose schedules说明“那些人的时间表”。

**The second survey included fewer first-year students than the first did.** did代included，比较的是两次survey包括的一年级学生人数，不是总学生人数。**as much a question of access as of motivation**表示同样涉及可达性与动机，并非二选一。

处理密集名词短语也要恢复关系：the effect of reduced staffing on evening access =减少人手对晚间可使用情况的影响。先找effect中心词，再分清of原因和on受影响对象。

## 例题解析

**Had the researchers relied only on completed forms, they would have overlooked people who could not use the online system.**

Had置首是不带if的过去反事实条件：If the researchers had relied…。主句would have overlooked表示本会漏掉。译：“研究者如果当时只依赖已填完的表格，就会忽略那些无法使用在线系统的人。”它不是在陈述“研究者确实只依赖表格”；条件形式告诉我们不要把假设误读为事实。

## 练习

先独立完成，再核对答案；开放题须按要点人工评分，不以是否逐字等同范文评分。

### 1

还原Only when the sample was enlarged did the pattern become clear为正常语序，并翻译only的限制。

### 2

翻译：What remains unclear is whether the improvement will last after the trial ends.

### 3

补出省略成分：The guide, if updated regularly, could remain useful for several years.

### 4

翻译：Not all benefits that are easy to measure are the most important ones.

### 5

写出Had the team consulted users, it would have noticed the barrier earlier的if版本，并说明是否断言团队当时咨询过用户。

### 6

解释比较：The revision raises as many questions as it answers. 是否表示只回答不提问？

### 7

词汇迁移：译：句法分析帮助我们还原省略的动词，并区分主张与范围限定。

### 8

词汇迁移：译：这个反事实条件不是已经发生的事实；后续分析必须保留这种区别。

## 参考答案与解析

### 1

The pattern became clear **only when the sample was enlarged**. “只有在样本扩大后，模式才变得清楚。”不是样本扩大前就清楚。

### 2

“仍不清楚的是，试行结束后这种改善是否会持续。”whether为间接疑问；will last属于待确认内容，不是作者保证。

### 3

if **it is** updated regularly。it=the guide，含被动。整句“指南如果定期更新，可能多年保持实用”；不是说已定期更新。

### 4

“并非所有容易衡量的益处都是最重要的益处。”not all不同于none；定语从句限制benefits的范围。

### 5

If the team **had consulted** users, it **would have noticed** the barrier earlier. 过去反事实语境通常表示当时并未这样做；不能当成“已咨询并发现”。

### 6

表示这次修订提出的问题与解答的问题一样多，通常暗含仍有不少待解之处。as many…as…是数量比较，不是“没有回答任何问题”。


### 7

Syntactic analysis helps us recover the omitted verb and distinguish the claim from its restriction of scope. help后动词并列，distinguish A from B。6分：信息3，搭配2，句法1。

### 8

The counterfactual condition does not describe an event that actually happened; subsequent analysis must preserve this distinction. 分号连接，actually happened受否定describe辖制。6分：信息3，词块2，句法1。
