句中“你刚说的”表示一个过去时态,说一种语言要用speak,如果是speak English,意思是:说英语,和题目的意思不符,而题目的意思是刚才说的话是不是英语?也就是,是不是用英语说的。此处表示用某种语言说话,要用介词in,所以此句可以翻译为:
Did you speak in English just now?(一般过去式)或
Have you spoken in English just now?(现在完成时)
Is it English what just you said ?
Were you speaking English (just now) ?
希望能帮到你 ^_^
Let's talk in English.
were you speaking English just now?
