Every student as well as some teachers who__ to visit the museum__ asked to be at the school gate before 7：30 in the morning .
A.are ;are  B.is; is C.are ;is D.is;are
这题啥意思啊 一点也没明白  为啥选C

句意为：每个学生,连同将要去博物馆参观的老师,都被要求早上7:30在校门口集合.
本题主要考察了两个语言点：定语从句和主谓一致问题.who引导的句子做teachers的定语从句,谓语动词应该用复数,与先行词teachers保持一致；如果是as well as 连接两个并列成分,对选择的谓语动词没有影响,即第二个空要填的动词应该与student保持一致,所以用单三形式.
希望你能看明白!
再问： 第二个空不明白
再答： 这个太复杂了，给你举个简单的例子，I，as well as Tom am to go to a party. 这个句子的主语是I，谓语动词要与主语保持一致，用am, as well as连接的成分并不做主语，所以在动词的选择上，不可以用is。 as well as, along with, with, together with, like, besides, in addition to，but连接两个名词作主语时，谓语动词都要和前面的名词保持一致。 希望你能明白
