同学你好~
一般小写就可以了，比如
His favourite foods are as follows: apple pie, fruit juice, and chocolate. 他喜欢的食物有下列东西：如苹果派，果汁和巧克力。

冒号后是句子，多数情况大写，有时也小写（英式英语常见），比如
My main objections are as follows: First of all, no proper budget has been drawn up. Secondly, there is no guarantee that ... 我主要的反对意见如下：首先，没有制定适当的预算。其次，无法保证 .....
In his most famous speech, he said: all men are created equal and must enjoy the equal rights that are given by God. 在他最著名的演讲中，他说：人生来是平等的，必须享受上帝所赋予的平等权利。

但如果在书名中要大写，比如
Language use and processing: A review.

祝同学学习进步~
