例如这段,开始的The first group 用的是过去时的单数was,然后后面的两个,The second group 和 The third group用的却是现在时的复数。是不是不太对?到底哪个对?
The first group was those who are risk-averse. If you are ….
The second group are those who are risk-tolerant. If you are ….
The third group he mentioned are those who are risk-seeking.
要看上下文。第一句前面有一个There were three. The first group was.....是紧跟这一句的。第二句和第三句是另外两个人在讲,陈述一般事实。。
