【分析】
本题要求用方框中所给单词的适当形式填空，解题思路为：先理解每句句意，再结合句子的语法结构（如比较级、名词复数、形容词修饰名词等），选择对应单词并进行正确变形。
【解析】
1. 句意：她每天锻炼一小时，所以变得更苗条更健康。由并列连词and后的healthier（形容词比较级）可知，此处需用slim的比较级，slim是重读闭音节形容词，比较级双写末尾辅音字母加er，故填slimmer。
2. 句意：山的平均高度约1500米。此处修饰名词height，需用形容词，average（平均的）符合语境，故填average。
3. 句意：从我家到学校大约两公里。数词two后接可数名词复数，kilometre的复数形式为kilometres，故填kilometres。
4. 句意：这个城市的天气通常比其他地方更宜人。由句中than可知，需用形容词比较级，pleasant是多音节形容词，比较级加more，故填more pleasant。
5. 句意：报纸有责任给读者事实。fact是可数名词，此处表泛指，需用复数形式，故填facts。
【答案】
1. slimmer 2. average 3. kilometres 4. more pleasant 5. facts

【解析】
1. 句中出现比较级标志词than，需用形容词比较级，结合后文“Betty is slimmer than Nancy”可知此处描述身高，故填taller；

5. 由“Betty is quieter”及语境可知Betty对学习更认真，serious是多音节形容词，比较级加more，故填more serious。
