what
if what u need is just a definition,ok ,"take sb./sth.from one place to another in a vehicle".this definition comes from Oxford Advanced Learner's English Dictionary Extended fourth edition.
in terms of "科学"（science）,it can generally be defined this way,"organized knowledge,esp when obtained by observation and testing of facts,about the physical world,natural laws and society",and it also refers to the study leading to such knowledge.
