OG17-697题，research作动词时的用法

装渣渣

在research用作动词，更多时候是表现为及物动词，直接加名词；但在少数情况下，具体到某个细分领域时，会加on/into.
#牛津词典#上，给出的例句基本都是及物动词的用法：
The amount of time and money being spent on researching this disease is pitiful.
We are researching the reproduction of elephants.
She researched a wide variety of jobs before deciding on law.
He researches heart disease.
The internet has reduced the amount of time it takes to research these subjects.
唯一一句不及物动词的例句：
She's researching into possible cures for AIDS.

此外，一般来说research作名词的时候会用介词的情况比较多，比如 do research on/into sth
