Question

________ Mary ________ Jack is listening to the report carefully, because they are both interested in it very much.

A．Neither; nor

B．Either; or

C．Both; and

D．Not only; but also

Answer 1

D  

解析试题分析：句意：不仅玛丽而且杰克认真听取了报告，因为他们都对它非常感兴趣。Neither; nor既不，也不，连接并列主语时，遵循就近原则；Either; or 或者，或者，连接并列主语时，遵循就近原则；Both; and两者都，连接并列主语时，谓语动词使用复数形式；Not only; but also不但，而且，连接并列主语时，遵循就近原则。根据because they are both interested in it very much可推知玛丽和杰克都认真听了，再结合后面的is就可知该选D。
考点：考查连词。
