If you want to talk with me ,please speak in English有何错误?If you want to talk with me ,please speak in English.请问此句有没有任何错误.请注意,是任何错误.

If you want to talk to me, please speak English.

是talk to,最好speak后面加sb..please speak in English有命令的口气.

If you want to talk with me , please speak English. 说某种语言我们用speak 加语言。
但可以说say sth. in English (语言)

有问题, 把前面的talk 改成speak 要好点.
词本身的搭配并没有问题. 请看如下金山词霸的例句.
speak in French
用法语讲话---金山词霸上的例句
talk with
与...交谈; 与...交换意见
To consult or confer with someone:
I talked with the doctor.
----金山词霸的例句

If you want to talk with me ,please speak in English有何错误?答：前一句没错,但“ please speak in English”一句中,动词speak为及物动词,后直接加上宾语,即为：speak + 语言in English,作为方式状语,可以表示“...

有，
say sth. in English
speak English
