3.There’s no doubt _________ Mr White’s lecture will be a great success.
A. that B. whether C. if D. which

答案是1.B 2.C 3.A
帮忙讲解以下

三道题的答案及解析:
1.是D不是B。whom引导定语从句,同时后面的turn to sb是“向某人求助”,因此to不能没有。
2. 选B不选C。 因为定语从句中的work out缺少宾语,所以本句是as(因为前面有so修饰先行词),as在从句中作宾语。而如果选择so that,则work out后面需要加it。
3. A that引导同位语从句,对doubt的内容进行说明。
