【分析】
本题考查英语词汇的适当形式填空，需结合词性、时态、固定句型、祈使句等基础语法规则解题：
1. 空格后是名词diet，需用形容词修饰，故将名词balance转换为形容词；
2. 从句为过去进行时，主句需对应一般过去时，故将动词变为过去式；
3. 固定句型要求用动词不定式作真正主语，需用不定式形式；
4. 空格修饰动词run，需用副词，故将形容词转换为副词；
5. 祈使句中and连接并列动词原形，需用动词原形；
6. screen为可数名词，此处表泛指多个屏幕，需用复数形式。
【解析】
1. 修饰名词diet需用形容词，balance的形容词为balanced，故填balanced；
2. 从句是过去进行时（were looking），主句用一般过去时，notice的过去式为noticed，故填noticed；

4. 修饰动词run需用副词，dangerous的副词形式为dangerously，故填dangerously；
5. 祈使句结构为“动词原形+其他+and+动词原形”，故填speak；
6. screen是可数名词，此处指多个电子屏幕，用复数screens，故填screens。

4. game为可数名词单数，此处泛指“一个游戏”，用不定冠词a；
5. start后接不定式作宾语，即start to do sth，故填to eat；
