很高兴为你解答.
保证正确率~!



正确答案是：
 【 Is 】not only the students but also their teacher required to attend the meeting
改为陈述句就是：
 Not only the students but also their teacher 【 is】required to attend the meeting.
【解析】：
你都知道是考主谓一致了,not only.but also 是就近原则,真正的主语是their teacher ,the students只不过是个“陪嫁”的.谓语动词随 their teacher 变化,故填 is .
祝开心~!答案是Are, 为啥呢答案说是are 就是 are 啊？ 强调的是 the teacher，不是the students。
