he has some problems__his work.请问用什么介词

选择D
have problem doing sth.
have a hard time doing sth.
have a difficult time doing sth.
have trouble doing sth.
have difficulties doing sth.
这些短语都是"做某事有困难"的意思

个人觉得是用 “on”比较妥当

with

C of doing
我凭语感觉得是，也不知道对不对。

如果是选择题，答案选D。have problems（in） doing=have difficulty （in） doing，如果是介词应该是with
