1. This is excellent information that she can pass on to her partner! 她可以把这条重要的信息传给她的伴侣

在这个定语从句中，that引导的关系词做pass on 的宾语，to后面表示对象状语，即she can pass the excellent information on to her parter.

2. The cost-roughly $800 a year for every American is passed on to consumers.

这句把pass on 的宾语提前，变成了被动形式

3. Jim: That will involve additional expenses for us, which we'll have to pass on to you as a rate hike. 吉姆：那意味我们会有额外的开销，而我们会把价格增加部分转嫁到你们身上。

which先行词作pass on的宾语

问题:

As in a previous study, the monkeys were given a third choice that would allow them to pass on to a new trial.

在之前的研究中，猴子们得到了第三种选择，使他们可以继续进行新的试验。

这句话中，that关系词作后面定语从句的主语，那pass on 的宾语是哪一个啊？？？

In this case， we want the message to pass on to the next module and not to be returned directly from this flow.

在本例中，我们希望消息传递到下一个模块，而不是直接由这个流返回。

want sb/sth to do sth,在这句话中，to pass on的逻辑主语是the message，既然to pass on是及物动词，那为什么也没有宾语啊？

恳请各位老师帮忙解释一下！
