please check the grammar of this sentence

语法很好!只有一个小小错误：
Q:Why are you interested in becoming a HealthEast volunteer?
A:I want to help others.Being a good listener and taking care of them is what patients need.
但是答案的意思有问题吧?为什么
“Being a good listener and taking care of them is what patients need.”
是你要做个 HealthEast volunteer 的理由呢?
建议你这样改：
“I enjoy taking care of people.Besides it helps me be a good listener."Besides it helps me be a good listener? 还是 Besides it helps me to become a good listener or Besides it helps me being a good listener? I think all of them are correct.Maybe u can help me to check this sentence too.Q: Please list any previous volunteer experiences.A:I have made PowerPoint for the church; I have stayed in the nursery taking/take care of childrenplease explain why.Besides it helps me be a good listener. Besides it helps me become a good listener.两者皆可。第二个问题建议这样改：A: I have made PowerPoint presentations at the church. I also have experience taking care of children in the nursery.含义和你的句子一样，不过语法上比较完整/正确。
