【分析】
本题为英语句式转换类题目,需分别处理被动语态转换、句子翻译、连词成句三类题型:1. 被动语态转换需将主动句的宾语变为被动句主语,对应时态的被动结构,补充动作执行者;2. 翻译需准确对应原句时态、定语结构,符合中文表达习惯;3. 连词成句需先确定核心主谓结构,再补充修饰成分,保证句子通顺合理。
【解析】
1. 原主动句中宾语为a space station,一般将来时被动结构为will be + 过去分词built,动作执行者用by us,故转换为My space dream is that one day a space station will be built by us on the moon.
2. 原主动句中宾语为some special kinds of energy resources,一般将来时被动结构为will be + 过去分词found,动作执行者用by people,故转换为Some special kinds of energy resources on the moon will be found by people.
3. 原句为现在完成时,“Humans have achieved”译为“人类已经实现了”,“many things that were once only dreams”译为“很多曾经只是梦想的事情”,组合后为人类已经实现了很多曾经只是梦想的事情。
4. 先确定核心结构I hope to do,build a satellite为hope的宾语,后面用不定式作目的状语,连接to collect the sun's energy and send it to Earth,故组合为I hope to build a satellite to collect the sun's energy and send it to Earth.
【答案】
1. My space dream is that one day a space station will be built by us on the moon.
2. Some special kinds of energy resources on the moon will be found by people.
3. 人类已经实现了很多曾经只是梦想的事情。
4. I hope to build a satellite to collect the sun's energy and send it to Earth.
