1. C. 词组. have difficulty (in) doing Sth. 做某事有困难.2. C. 我们正要叫你,你就进来了.A的话应该用be about to do 这个结构表示正要做某事。when在这类句子里表示就在这时，某件事情发生了。如：They were watching TV when the phone rang.他们正在看电视，就在这时，电话铃响了。on the point of正要。。。。的时候

1 选C 固定的搭配：have difficulty in sth have difficulty (in) doing sth have no difficulty finding his home.毫不费劲的找到了他家。2 选C be about to do 或 on the point of donging 表示即将做某事 when和while都能表示“当。。。的时候”， 但是当一个瞬时动作发生的时候只能用when,while就不能了。你进来的时候我正要给你打电话。“进来”是瞬时动作。
