感恩节美国人会说“I am so thankful to have you in my life.”或“I am grateful for your support.”。Thankful和grateful两个单词意思相近，因此很多人容易混淆它们。中文里“谢谢”是分成了三种层次的，先是感谢，再来是感激，最后是感恩。同样的，thankful和grateful也有使用意义上的差异。
可以通过下面例句来感受一下：
Jack was grateful to his teachers and also thankful that he had passed his exams. ✏GRATEFUL有人帮了你，你真心感谢他，这个时候应该用grateful 。
be grateful to someone for something感激（某人）做了某事
I am grateful for the support we have received from family and friends.我很感谢所有来自家人和朋友的支持。THANKFUL ♂松了一口气，“还好没事”而进行的感谢应该用thankful。
1. be thankful (to someone) for something感激（某人）做了某事
Lucy is thankful to Jack for the help.Lucy很感激Jack的帮忙。2. be thankful for someone/something感谢某人/某事的存在
I'm thankful for you.还好有你。3. be thankful + that从句
I was just thankful that no one was killed or hurt.我只是很感激没有任何人伤亡。写作分享不易，如果觉得文章不错，欢迎转发点赞，关注本人。
