Answer 1

1.答案错误,应该是was.
该题先行词是the only one,而关系代词who就相当于先行词,所以定语从句的谓语动词应该用单数was而不是复数were.
如果句子是：He was one of the students in our class who (were)accepted by Tsinghua University.
则答案就该用were.
2.定语从句中,如果先行词被the only休修饰时,则关系代词只能用that.
3.反义疑问句,前句主干是it is...,后面不是isn't it能是什么呢?
主从复合句的反义疑问句,一般都是根据主句来变.
4.must有个特殊含义是“一定要,偏偏要”的意思.
如：Must you leave now?你现在一定要非走不可吗?
5.虽然两者表示的含义其实是一样的,但是侧重点还是不同的.
both侧重点是“两者”,而either的侧重点则是“（两者中）任意一者”.
而该题从后面的意思来看,侧重点在“两者都”上.
