_________the answers ready will be of great help for a job interview 为什么用Having

_________the answers ready will be of great help for a job interview 为什么用Having

动词作主语都要加ing 没有为啥

这时动名词"gerund", "Having the answers ready"在这里做动名词主语,动名词里动词全部都要-ing形式, 譬如"Playing computer games is fun.", "Swimming in the lake is great."
