三、核心转换规则(3 步走)
变主语:把主动句的宾语变成被动句的主语
变谓语:will+动词原形 → will+be+动词过去分词(时态保持一般将来时)
变状语:原主语变 by 短语(可省略),其他状语不变
【强化练习】
1. The Great Wall (know) to people all over the world.
2. The telephone (invent) by Alexander Bell in 1876.
3. A new space station (build) on the moon in the near future.
4. The 2028 Olympic Games (hold) in Los Angeles.

1. is known
2. was invented
3. will be built
4. will be held

【分析】
本题考查被动语态的时态应用，解题思路为：先判断句子主语与谓语动词的被动关系（主语是动作的承受者），再根据句中的时间标志确定对应的时态，最后结合被动语态的结构填写正确形式。具体需掌握不同时态下被动语态的构成规则，结合时间状语判断时态即可解题。
【解析】
1. 主语The Great Wall是动词know的承受者，描述客观事实，用一般现在时被动语态，结构为“am/is/are + 过去分词”，主语为单数，故填is known；
2. 主语The telephone是动词invent的承受者，时间状语in 1876表过去，用一般过去时被动语态，结构为“was/were + 过去分词”，主语为单数，故填was invented；
3. 主语A new space station是动词build的承受者，时间状语in the near future表将来，用一般将来时被动语态，结构为“will + be + 过去分词”，故填will be built；
4. 主语The 2028 Olympic Games是动词hold的承受者，表将来事件，用一般将来时被动语态，结构为“will + be + 过去分词”，故填will be held。
【答案】
1. is known 2. was invented 3. will be built 4. will be held
【知识点】
一般现在时被动语态；一般过去时被动语态；一般将来时被动语态
【点评】
本题围绕被动语态的时态转换展开，结合时间标志判断时态是解题关键，需牢记不同时态下被动语态的构成规则，属于英语语法中的基础题型，适合巩固被动语态的核心用法。

Since human history began, people have wondered about the stars. Many ancient cultures believed these points of light
1. (be) from gods, but with scientific development, we learnt stars are real, sun-like
places, much farther than imagined. This raises the question: Can we visit the stars one day?
The man-made object which has travelled
2. (far) from Earth is Voyager 1. This spacecraft was launched in 1977. In case Voyager 1 is found by alien life, a special record with sounds and pictures from Earth
3. (carry) on board. Now, Voyager 1 is an amazing 23.5 billion kilometres from Earth, but that is still a long way from Earth's nearest star, Proxima Centauri.
The challenge of visiting the stars gets even bigger for space flights with humans. The furthest that any human has gone in space is only about 400,000 kilometres, around
4. other side of the moon. Time is a big problem. At present, even a journey to the planet Mars will take around six to nine months. What will the astronauts eat and drink during this period? And how about their health and
5. (safe)? These problems grow when we talk about visiting another star. It might take hundreds of thousands of years to get there!
Scientists, however, believe that visiting the stars is not a
6. (complete) wild dream. One idea is to have the astronauts sleep during their journey. Another is to develop much faster spacecraft. While this is not possible right now, with nations and scientists cooperating
7. one another, there is hope that the necessary technology
8. (develop). Humans have set foot on the moon, successfully landed rovers on Mars, and even photographed other

10. people once dreamt.

1. were
2. furthest
3. is carried
4. the
5. safety
6. completely
7. with
8. will be developed
9. galaxies
10. as

【分析】
1. 第1空：根据时间状语“ancient cultures（古代）”，句子需用一般过去时，主语为复数，故be动词用were；
2. 第2空：语境表示“离地球最远的人造物体”，需用far的最高级furthest；
3. 第3空：主语a special record与动词carry为被动关系，陈述客观事实用一般现在时的被动语态，故填is carried；
4. 第4空：固定搭配“the other side of...”表示“……的另一边”，需用定冠词the；
5. 第5空：and连接并列名词，前面是health，此处需用名词safety对应；
6. 第6空：修饰形容词wild需用副词，complete的副词形式为completely；
7. 第7空：固定搭配cooperate with表示“与……合作”，故填介词with；
8. 第8空：主语the necessary technology与develop为被动关系，表将来的被动动作，用一般将来时的被动语态will be developed；
9. 第9空：other后接可数名词复数，galaxy的复数为galaxies；
10. 第10空：as引导方式状语从句，表“正如”，符合语境。
【解析】
本题为阅读语境下的语法填空，需结合语境和语法规则逐一确定答案：
1. 一般过去时中，复数主语对应be动词were，故填were；
2. 表示“最远的”，用far的最高级furthest，故填furthest；
3. 被动语态（一般现在时），结构为is+过去分词，故填is carried；
4. 固定搭配the other side，故填the；
5. 名词形式，safety与health并列，故填safety；
6. 副词修饰形容词，completely修饰wild，故填completely；
7. 固定搭配cooperate with，故填with；
8. 一般将来时的被动语态，结构为will be+过去分词，故填will be developed；
9. 可数名词复数，galaxies，故填galaxies；
10. as引导方式状语从句，表“正如”，故填as。
【答案】
1. were
2. furthest
3. is carried
4. the
5. safety
6. completely
7. with
8. will be developed
9. galaxies
10. as
【知识点】
动词时态语态、词性转换、固定搭配
【点评】
本题围绕人类探索恒星的话题，考查基础语法知识与固定搭配的运用，需结合上下文语境分析每个空的语法形式，难度适中。
