【分析】
本题解题思路分为两步:第一步,掌握否定前缀un-和im-/in-的用法,二者均可构成形容词的否定形式,需结合所给单词,用对应前缀组成否定形容词;第二步,分析每个句子的语境,判断所需的否定含义,再从组成的新词中选择合适的单词填入句子。
【解析】
1. 先根据否定前缀规则组成新词:
用un-构成的否定形容词:safe→unsafe,friendly→unfriendly,tidy→untidy,healthy→unhealthy,important→unimportant,common→uncommon;
用im-/in-构成的否定形容词:proper→improper,formal→informal,possible→impossible,perfect→imperfect;
2. 结合句子语境选词填空:
1. 深河里游泳是不安全的,填unsafe;
2. 邻居从不打招呼,看起来不友好,填unfriendly;
3. 卧室需要打扫,说明不整洁,填untidy;
4. 吃太多垃圾食品对身体不健康,填unhealthy;
5. 夏天这个城市下雪是不常见的,填uncommon;
6. 别担心那些不重要的小事,填unimportant;
7. 正式派对穿牛仔裤是不合适的,填improper;
8. 我们可以边喝咖啡边进行非正式的聊天,填informal;
9. 一天完成这个大任务是不可能的,填impossible。
【答案】
un-: unsafe, unfriendly, untidy, unhealthy, unimportant, uncommon
im-/in-: improper, informal, impossible, imperfect
