老师好！
University officials may ask students to type their exam answers on a computer rather than use a pen.
We live in a stress-filled world. Ratherthan only looking for ways to change the stress-filled situations, look forstress that can work for you.
第一句为何ratherthan 后接了动词原形use？而第二句Ratherthan 后却接了looking，而不是动词原形look呢？
ratherthan是介词，还是连词呢？顺便请教老师，other than 是介词还是连词呢？
谢谢！
在 rather than 后面可以接带 to 或者不带 to 的动词不定式，也可以接动名词。可以把动名词前面的 rather than 看作是介词。
other than 可以作介词，也可以作连词。
