【1】词性的选择：单词拼写不但要根据汉语解释写出相应的单词，而且要根据句子意思和结构选择正确的词类。
1.It is_______ (稍微)colder today than it was yesterday.
解析：根据句意：今天天气比昨天的天气稍微冷点。“稍微”在句中是副词，修饰colder.故答案为：slightly.
2.The story is written by an _______ (澳大利亚)engineer.
解析：根据句意：这个故事是由一位澳大利亚工程师写的。“澳大利亚”做定语，故答案是形容词：Australian.
3.My trip to Jiuzhaigou is really an u_______ experience.I still remember it.
