英语语法三单问题

Question

e.g.A good leader should not only has higher education but also has the ability to teach others. 这里要用have还是has，主语后面跟了should,also,must这类词后再加动词还需要写成三单吗？

Answer 1

should 后面接have, 原型动词，两个都是have, 因为should 的覆盖范围是have higher education 和 have the ability to teach
一般是has , have 你还是得看助动词 must should的覆盖范围 （governing range), 如果扩于全句，那么用原型不用三单。。。

Answer 2

这里涉及到两个知识点;
第一： not only ... but also
若连接两个成分作主语，其谓语通常与靠近的主语保持一致
not only 用在句首时，句子需要倒装
第二：should must这类词后面跟动词的话必须用动词原形

在这里not only 。。。but also连接的主语为同一个“a leader”谓语动词需要用第三人称单数形式，两处都应该用has本回答被网友采纳
