您好，主要是看学校的要求来哦。

1.看学校要求
2.通常不需要
3.可以

Typewritten is fine. You do not need to write the school name and address on the essay, but that also depends on whether they ask you to fill in your information. Just follow the directions on the application form. For the question, does it say, "Write anything that you are passionate about." If that is the case, then you should write something that you love to do and the most important thing is that the school hears your voice.

您好！您说的申请作文，我理解是指的文书吧？文书是打印还是手写，各个学校要求不一样，譬如DE的ST ANDDREWS就要求全部手写，但多数学校要求在学校的申请系统里输入文书，也有的学校使用的是SSAT申请系统或者GATEWAY申请系统。这都要根据您的申请学校的要求来定。谢谢阅读，希望能帮到您。
