问题描述:

---Mary---Tom speaks good chinese,so they can communicaye with there chinese student very well
空格处填A、both;and B、not only;but also
及 原因

B、not only;but also
speaks 是单数形式 不能用both--and---

B
A后面用speak

B
主要注意speaks,是第三人称单数.所以排除both;and (复数)
not only;but also 采用就近原则

B Not ....only....
因为谓语动词用的是第三人称单数,不能用both ... and,
But ... also不对意
