(1) The villagers dug a well to get groundwater for drinking. (对划线部分提问)
(2) To my surprise, her curiosity about the world never seemed to disappear. (保持句意基本不变)
I
(3) I must back up all my important files first. Then I will update my phone’s software. (两句合并为一句)
I
(1) The villagers dug a well to get groundwater for drinking. (对划线部分提问)
Why
did
the villagers dig a well?(2) To my surprise, her curiosity about the world never seemed to disappear. (保持句意基本不变)
I
was
surprised
to find that her curiosity about the world never seemed to disappear.(3) I must back up all my important files first. Then I will update my phone’s software. (两句合并为一句)
I
won't
update my phone’s software until
I back up all my important files.答案
(1) Why did (2) was surprised (3) won't, until
解析
【分析】
1. 第(1)题：划线部分是表目的的状语，对目的提问用疑问词Why；原句是一般过去时（动词dug为过去式），构成特殊疑问句需借助助动词did，主语后用动词原形，因此填Why did。
2. 第(2)题：“To my surprise”的同义表达是“I was surprised to...”，原句时态为一般过去时，主语是I，be动词用was，因此填was surprised。
3. 第(3)题：原句逻辑是“先备份文件，再更新软件”，对应“not...until...”（直到……才……）结构，即“我不会更新软件直到备份重要文件”，时态用一般将来时的否定式won't，因此填won't, until。
【解析】
(1) 对目的状语提问用疑问词Why；原句为一般过去时，特殊疑问句结构为“疑问词+did+主语+动词原形”，原句动词dug的原形是dig，故填Why did。
(2) “To my surprise”可转换为“I was surprised to...”，原句时态为一般过去时，主语I搭配be动词was，故填was surprised。
(3) 两句合并需体现“直到……才……”的逻辑，用连词until，一般将来时的否定式won't，故填won't, until。
【答案】
(1) Why did (2) was surprised (3) won't, until
【知识点】
句型转换、特殊疑问句、连词until的用法
【点评】
本题为英语基础句型转换题，考察学生对特殊疑问句、同义表达及常用连词的掌握，属于英语基础应用类题目，难度较低。
