1.B
【句意】我想我把灯关了，不过我得回去确认一下。
【解析】语法结构——and引导并列结构。将各个选项带入后发现“make sure确认”在结构和意思上都正确，故B项正确。A项和D项中的be动词与and前面的“go”不形成对应，故可直接排除；C选项中的“feel sure确信”在意思上不符合。

2.C
【句意】最低收入水平和最高收入水平人群之间的差距已大幅地增加，且还在继续增加。
【解析】同形词辨析。successfully“成功地；顺利地”；succinctly“简洁地；简便地”；substantially“实质上；大幅度地”；sufficiently“充分地；足够地”。由句中关键词“gap差距”与“level of income收入水平”的对应知“大幅度地”符合语境，故C项正确。
