Lesson 43 · 情态动词的意义与形式
阅读材料(本站原创): The pilot was able to land before the storm arrived.
练习 1
填 to/for:The pilot managed ___ land safely.
参考答案与解析
答案: to
解析: manage 后用 to 不定式表示成功完成。
表达迁移: 写三句艰难行程,包含限制、成功行动与后续支援。
表达参考与点评
The pilot was able to land before the storm arrived. There was little fuel left. A support team brought supplies the next morning.
第一句的组织方式:was able to land 描述这次成功结果,before 从句限定时间,storm arrived 是之后的事件。其后的两句补充本课情境中的具体发展,作答时应保持人物和时间指代一致。重点自查:managed landing 不符合常用搭配;用 managed to land。
Lesson 44 · 真实条件句
阅读材料(本站原创): If we keep to the path, we can reach the village before dark.
练习 1
填 keep:If we ___ to the path, we can reach the village.
参考答案与解析
答案: keep
解析: 真实未来条件从句通常用现在时。
表达迁移: 规划一次徒步,写两条条件与对应行动,避免把可能当成保证。
表达参考与点评
If we keep to the path, we can reach the village before dark. The map shows a stream halfway along the route. We will rest there if everyone agrees.
第一句的组织方式:if 从句用一般现在时 keep,主句 can reach 表条件下的能力或可能,before dark 为时间界限。其后的两句补充本课情境中的具体发展,作答时应保持人物和时间指代一致。重点自查:If we will keep ... 在普通真实条件句中多余;用 If we keep。
Lesson 45 · 被动语态与信息重点
阅读材料(本站原创): The missing money has been returned in a plain envelope.
练习 1
填 has/have:The money ___ been returned.
参考答案与解析
答案: has
解析: money 是不可数名词。

表达参考与点评
The missing money has been returned in a plain envelope. No name was written on it. The owner thanked whoever had sent it.
第一句的组织方式:money 不可数,助动词用 has;has been returned 是完成时被动,in 表容器。其后的两句补充本课情境中的具体发展,作答时应保持人物和时间指代一致。重点自查:money have been 应为 money has been;不可数名词按单数处理。
Lesson 46 · 数量表达与范围
阅读材料(本站原创): The overnight train cost more but offered fewer comfortable seats.
练习 1
选 less/fewer:The carriage had ___ seats.
参考答案与解析

表达参考与点评
The overnight train cost more but offered fewer comfortable seats. We changed to a daytime service on the return trip. It was cheaper and gave us a better view.
第一句的组织方式:cost 是过去式,与原形同形;more 省略比较中的 money,fewer 修饰可数复数 seats。其后的两句补充本课情境中的具体发展,作答时应保持人物和时间指代一致。重点自查:fewer comfort 不对,comfort 通常不可数;可说 less comfort 或 fewer comfortable seats。

阅读材料(本站原创): The cellar was said to be haunted, but no one had evidence.
练习 1
补全:The house was said ___ be empty.

解析: be said to do 是报道被动结构。
表达迁移: 写一段传闻调查,先标明说法,再写观察结果与处理行动。
表达参考与点评
The cellar was said to be haunted, but no one had evidence. A camera later recorded a loose window opening in the wind. The owner repaired its latch.
第一句的组织方式:was said to be 是被动报道结构;but no one had evidence 限定传闻可信度,不确认鬼魂存在。其后的两句补充本课情境中的具体发展,作答时应保持人物和时间指代一致。重点自查:evidence 通常不可数,不写 an evidence;可说 a piece of evidence。
Lesson 48 · 时间、原因与让步从句
阅读材料(本站原创): As soon as the dentist removed the mirror, I asked a question.
练习 1
选连接词:___ she finished speaking, I replied.(一……就……)

表达迁移: 写一次不方便说话时的交流,说明非语言回应和随后提出的问题。
表达参考与点评
As soon as the dentist removed the mirror, I asked a question. I wanted to know when I could eat. She gave me clear instructions before I left.
第一句的组织方式:As soon as 从句给出先发生的动作,主句 asked 紧接其后;两者都是具体过去事件。其后的两句补充本课情境中的具体发展,作答时应保持人物和时间指代一致。重点自查:while he removed the mirror 不一定等于拿开之后;表达紧接应使用 as soon as。
