语法很好!只有一个小小错误：

　　Q:WhyareyouinterestedinbecomingaHealthEastvolunteer?

　　A:Iwanttohelpothers.Beingagoodlistenerandtakingcareofthemiswhatpatientsneed.

　　但是答案的意思有问题吧?为什么

　　“Beingagoodlistenerandtakingcareofthemiswhatpatientsneed.”

　　是你要做个HealthEastvolunteer的理由呢?

　　建议你这样改：

　　“Ienjoytakingcareofpeople.Besidesithelpsmebeagoodlistener."

　　Besidesithelpsmebeagoodlistener?还是BesidesithelpsmetobecomeagoodlistenerorBesidesithelpsmebeingagoodlistener?Ithinkallofthemarecorrect.Maybeucanhelpmetocheckthissentencetoo.Q:Pleaselistanypreviousvolunteerexperiences.A:IhavemadePowerPointforthechurch;Ihavestayedinthenurserytaking/takecareofchildrenpleaseexplainwhy.

　　Besidesithelpsmebeagoodlistener.Besidesithelpsmebecomeagoodlistener.两者皆可。第二个问题建议这样改：A:IhavemadePowerPointpresentationsatthechurch.Ialsohaveexperiencetakingcareofchildreninthenursery.含义和你的句子一样，不过语法上比较完整/正确。
