【分析】这类题目要求根据汉语提示和句子语境填写正确的英语单词，解题思路为：①理解每句句意，明确所需单词的词性；②结合汉语提示确定单词的基本形式；③根据句子的时态、单复数等语法规则调整单词形式，确保符合语境。
【解析】1. 空格处修饰名词scarf（围巾），需用形容词，汉语提示“紫色的”对应单词purple，直接填写。2. 时间状语last night（昨晚）表明句子为一般过去时，“下载”的动词过去式是downloaded，符合时态要求。3. 固定结构“one of + 形容词最高级 + 可数名词复数”表示“……之一”，“诗人”的复数形式为poets，符合结构要求。4. 数词two（两个）后需接可数名词复数，“女警察”的复数是不规则变化的policewomen，符合语法。5. 空格处作表语，需用形容词，汉语提示“聋的”对应单词deaf，直接填写。

二、根据句意，用关系代词that、which或who填空
1. This is the book I borrowed from the library last week.
2. It's hard to say goodbye to the lovely teachers have spent the past three years with us.
3. The computer my father bought for me last year works very well.
4. —Do you know the young lady your mother is talking to?

5. Everyone was surprised at the photo was taken by Thomas in the deep sea.

1. that/which 2. who/that 3. that/which
4. who/that 5. that/which

【分析】首先明确关系代词的选择规则：当先行词是物时，关系代词在从句中作主语或宾语，可用that或which；当先行词是人时，关系代词在从句中作主语或宾语，可用who或that。解题时先确定每句的先行词，再判断关系代词在从句中的成分，从而选择合适的关系代词。
【解析】1. 先行词是the book（物），关系代词在从句中作borrow的宾语，故填that/which；
2. 先行词是the lovely teachers（人），关系代词在从句中作主语，故填who/that；
3. 先行词是the computer（物），关系代词在从句中作bought的宾语，故填that/which；
4. 先行词是the young lady（人），关系代词在从句中作介词to的宾语，故填who/that；
5. 先行词是the photo（物），关系代词在从句中作主语，故填that/which。
【答案】1. that/which 2. who/that 3. that/which 4. who/that 5. that/which
【知识点】定语从句，关系代词用法
【点评】本题考查定语从句中关系代词的基础用法，需掌握先行词的属性（人/物）及关系代词在从句中的成分，是初中英语语法的核心基础考点，难度适中。
