His first experiment, nearly 30 years age, involved memory: training a person to hear and then repeat a random series of numbers.
【参考译文:差不多30年前,他的第一个实验与记忆力直接相关,即训练一个人听一系列随机的数字,然后再重复这一系列随机的数字。】
我的问题是:
(1) 这个句子中的动词train为什么要写成现在分词的形式?
(2) to hear改成hearing可以吗?
(3) repeat为什么不写成repeating或to repeat?
谢谢老师!
刘老师似乎又忽略了分词状语时,其逻辑主语应该是句子的主语。本句中主语experiment=training sb to do sth.
词典的解释和例句:train (transitive): to teach someone to do a particular job or activity.
train someone to do something:
They were training him to use the new security system.
因此,动词train sb to do sth的主语应该是人,而不是experiment。
冒号的作用之一为引出同位语。例如
She suggested that the most improtant factor had been overlooked: the cost.
the cost为the most important factor的同位语。
这个例句和本句类似。因此本句中的training...不是现在分词短语作状语,而是动名词短语作主语experiment的同位语。

我的问题是:

【答】training a person to hear and then repeat a random series of numbers,是现在分词短语,作伴随状语。因为involve 跟train 有主有次,不是并列关系,所以,一个是谓语动词,一个是非谓语动词(现在分词)。
(2) to hear改成hearing可以吗?
【答】不可以。train sb. to do sth. 训练某人做某事。
(3) repeat为什么不写成repeating或to repeat?
【答】repeat和 to hear是并列的宾语补足语,承前省略了to。
