问题 The opening ceremony is a great occasion. It is essential _______ for that.
选项 A、for us to be prepared
B、that we are prepared
C、of us to be prepared
D、our being prepared
答案 A
解析 本题考查语法规则和词汇知识。for us to be prepared for that为不定式复合结构，在句子中充当真正的主语(it 是形式主语)。essential还可以用于下列结构：It is essential that．．．，但that从句中的谓语动词需要用虚拟语气形式，所以B不对。essential不引导动名词复合结构，所以D也不对。essential强调所要做的事，而非描述做事的人，所以C也不妥。本题译文：开幕式是一个很重大的场合。我们必须为此做好准备。
