rememberthat在句首充当什么成分

充当宾语，例如：

1、I seem to remember that Sam told a number of lies.我好像记得萨姆说过不少谎话。

2、It is important to remember that each person reacts differently.重要的是要记住每个人的反应不同。

3、Remember that time she picked up my daughter when I was ill?还记得那次我生病，她替我接女儿吗

remember that 在句首，是祈使句，动词开头。意思是”记住…”that 引导一个宾语从句，做remember的宾语，“要记住”的内容。
