have difficulty doing

difficult 形容词

difficulty 名词

有困难 使用名词

have difficulty doing
difficult 是形容词，当然不会跟在动词后面

是HAVE DIFFICULTY DOING
因为DIFFICULT是形容词，DIFFICULTY是名词，HAVE后用名词，即所谓的有困难，一般使用DIFFICULT是用IT IS DIFFICULT TO DO SOMETHING

have difficulty doing
前者应该是it 's difficult to do

have difficulty doing

difficult 是形容词.

have some difficult to do;
have difficulty (in) doing.
