The rest of the novel ___ very interesting. A were B are C is D seem
第一道题里的真正主语是小说.既然小说是单数,那单数的一部分当然更是当成单数来处理了.
The rest of the people __to work in that city. A sent B were sent C was sent D have sent
第二道题则不同,因为people是复数.假如原来有十个人,还剩下三个,那当然还是复数了.这里是有people这个主要来决定的,不过剩下是不是还有一个（无从知道）.
相信帮您解决了难题.请及时采纳.谢谢!
