帮我看看这句子是不是病句,Aunt,you buy me shoes I received,shoes are very nice,thank aunt.With aunt's efforts,I will study harder.

要是书面的话，这个句子完全不能用啊（不如说放到作文里）
我帮你改改吧。
Aunt,I have received the shoes (which) you bought for me.The shoes are very nice.With your efforts,I will study harder.

这个句子应该说是病句，可以这样写：
Aunt, I have received the shoes you bougut me ,and they are very nice . With your effort ,I will study hander.
希望对你有帮助呵

Aunt, I have received the shoes you bought me. They're very nice. Thanks. I'll study harder with your help.

Aunt, I have received the shoes you bought for me . The shoes are very nice. thank you. With aunt's efforts, I will study harder.

有吧时态错误buy 改为bought .shoes应该说a pair of shoes 还有thank aunt没有这样的说法吧我认为扩充一下thanks,my aunt .
仅做参考,

是病句，可以改为Aunt ,I received the shoes you buy for me.the shoes are very nice,thank you.
With aunt's efforts,I will study hard
