帮忙看一下这道题！英语题，高手请进！求你了

A
考点:主谓一致
做此题应先把语序还原 he and his friend ____ speak what language
变为疑问句时就需要将助动词提前
句中主语为he and his friend为复数
故谓语应用复数形式 助动词也应为复数形式~
OVER

What language (do) he and his friend speak?

答案：A. do

因为主语为he and his friend为复数

the answer should be A
if you transfer this sentence back to regular order, it looks the same as:
they all speak Chinese-Do they speak Chinese?

A
he and his friend是两个人 用and并列的两个都是主语
所以主语是复数
用do

选A哦，如果只有第三人称单数he,则用does，但这里的he and his friend 中，and 表并列，所以应是复数，所以选A

用do ,他和他的朋友们，是第三人称复数，所以用do
