插入语为句子形式时,插入语可以缺少构成句子的必要语法成分吗?
如下面这句话中的插入语 research indicates,明明 indicate 是及物动词,为什么它可以缺少宾语?(虽然从语义上来看,它的宾语是后面的整句话,但毕竟后面的不属于插入语的一部分)
While we sleep, research indicates, the brain replays the patterns of activity it experienced during waking hours, allowing us to enter what one psychologist calls a neural virtual reality.

Research indicates that while we sleep, research indicates, the brain replays the patterns of activity it experienced during waking hours, allowing us to enter what one psychologist calls a neural virtual reality.
这个句子中,主句research indicates称为引述分句,间接引语为其宾语从句。主句为主要信息,侧重研究表明这个事实。
While we sleep, research indicates, the brain replays the patterns of activity it experienced during waking hours, allowing us to enter what one psychologist calls a neural virtual reality.
这个句子称为自由间接引语,即引语作了主句,引述分句作为插入语置于句末或插入句中,用逗号分隔。引语为主句,是句子表达的主要信息,研究表明这一点只是补充信息。
国内非英语专业英语教学没有介绍自由间接引语。你可以参读章振邦《新编高级英语语法》自由间接引语。
