解析
【分析】
这是一篇环保主题的语法填空题，解题思路为：先通读全文把握文章大意，再结合每个空格的前后语境、语法规则（如定语从句引导词、介词后动名词、形容词比较级、被动语态、主谓一致、固定搭配、冠词、名词复数、反身代词、形容词转换）逐一确定答案，最后完成词汇拓展的词性和词义判断。
【解析】
1. 空格处引导定语从句，先行词为指物的名词changes，且在从句中作主语，故用关系代词that/which；
2. 介词for后需接动名词作宾语，故将protect变为protecting；
3. much修饰形容词比较级，表“更久”，故long变为longer；
4. 电费账单是“被减少”，需用一般将来时的被动语态（will be+过去分词），故reduce变为reduced；
5. 定语从句先行词为不定代词someone，谓语动词用第三人称单数形式，故need变为needs；
6. 固定搭配in need意为“需要帮助的”，符合语境；
7. easy以元音音素开头，泛指“一个习惯”，用不定冠词an；
8. one of后接可数名词复数，cause的复数为causes；
9. 此处表示“问你自己”，用反身代词yourself；
10. be动词后需接形容词作表语，use的形容词形式为useful；
读后词汇拓展：1. bulb为名词，意为“灯泡”；2. device为名词，意为“设备”。
【答案】1. that/which 2. protecting 3. longer 4. reduced 5. needs 6. in 7. an 8. causes 9. yourself 10. useful；读后词汇拓展：1. n. 灯泡 2. n. 设备
