“咳出”常见的英文表达是 cough up,它强调通过咳嗽的动作将体内的东西(如痰、异物等)排出。例如:
He coughed up some thick phlegm.(他咳出了一些浓痰。)
The doctor told him to try to cough up the object stuck in his throat.(医生让他试着把卡在喉咙里的东西咳出来。 )
此外,根据具体语境,还可以用以下表达:
expel by coughing :侧重于强调通过咳嗽这种行为将东西排出体外,较为正式。例如:The patient managed to expel the foreign body by coughing.(病人设法通过咳嗽将异物排出体外。 )
bring up (something) by coughing: “bring up”有“使……出现;呕出;咳出”等意思,此表达更加强调咳出这个动作的结果,即把东西弄出来。例如:She tried to bring up the mucus by coughing.(她试图通过咳嗽把黏液咳出来。 )
