D解析分析:答句改为完整句的话就是The scientists have been there for about two years.由于是副词there,所以介词被省略了,还原的话应该是have been in(一直在某地),for about two years就表示have been there的时间长度。该用how long.(延伸)“for+时间长度”在句子中担任状语,表示动作或状态的持续时间长度,用how long来提问。在It takes+时间,spend+时间的句型里,时间是句子中的宾语,提问时也用how long,如:It took him two hours to do the work.How long did it take him to do the work?
