1So difficult ______ it to work out the problem that I decided to ask Tom for advice.
A．I did find B．did I find
C．I have found D．have I found
解析：以so＋adj./adv.开头的句子要在主句中进行部分倒装。句意：我发现这个问题是那么的难，就问了汤姆。
答案：B
2—______ he said at the meeting made everyone present angry.
—Yes.We all ______ him of his rudeness.
A．That；accused B．What；accused
C．That；charged D．/；charged
解析：what引导主语从句并在从句中作said的宾语；accuse sb.of sth.“因……而指责某人”。故只有B项符合题意。
答案：B
