挺友好的英语怎么说

"挺友好的" 英文常用说法是 "quite friendly"。

这个表达方式来自英语中的副词 "quite"，意思是 "相当"、"非常"，常用来加强形容词的程度。例如：

That restaurant is quite expensive. (那家餐馆很贵。)
She is quite talented. (她相当有才华。)

"Friendly" 是形容词，意思是 "友好的"、"亲切的"。例如：

He has a friendly smile. (他有着友好的微笑。)
The staff at the hotel were all very friendly. (酒店的员工都很友好。)

所以，"quite friendly" 的意思就是 "相当友好的"。例句如下：

My new neighbor is quite friendly. (我的新邻居挺友好的。)
The atmosphere at the party was quite friendly. (聚会氛围挺友好的。)
