1. C. 詞組. have difficulty (in) doing Sth. 做某事有困難.2. C. 我們正要叫你,你就進來了.A的話應該用be about to do 這個結構表示正要做某事。when在這類句子里表示就在這時，某件事情發生了。如：They were watching TV when the phone rang.他們正在看電視，就在這時，電話鈴響了。on the point of正要。。。。的時候

1 選C 固定的搭配：have difficulty in sth have difficulty (in) doing sth have no difficulty finding his home.毫不費勁的找到了他家。2 選C be about to do 或 on the point of donging 表示即將做某事 when和while都能表示“當。。。的時候”， 但是當一個瞬時動作發生的時候只能用when,while就不能了。你進來的時候我正要給你打電話。“進來”是瞬時動作。
