问题 What is said to be the best way to conserve energy nowadays? [br] Some countries have tried to jump-start the market of heat pumps by ______.
选项 A、upgrading the equipment
B、encouraging investments
C、implementing high-tech
D、providing subsidies
答案 D
解析 本题问“一些国家已经通过什么方式开启加热管道的市场?”根据题文中“jump-start the market of heat pumps”可将相关部分定位于小标题为“Comfort Zone(舒适区)”部分。全文第九自然段最后一句话提到“Several countries have used subsidies to jump-start the market...”，即“数个国家已经投资开启这一市场。”也就是说，通过投资的方式开启加热管道市场。因此，D项“提供投资”正确。A项“升级设备”、B项“鼓励投资”、C项“利用高科技”文中并未提及。
