(单选题)
New Year party is a great occasion. It is essential ______ for that.
A.that we are prepared
B.for us to be prepared
C.our being prepared
D.of us to be prepared
参考答案:B
参考解析:
考查介词for的用法及不定式作主语。句意:新年晚会是个很好的场合。我们必须为此做好准备。这里考查固定句型:It is + adj.(描述事物性质和特征等) + for sb. to do sth.意为“对某人来说做某事是怎么样的”。A选项中要用虚拟语气,应将are修改为(should)be;D选项中It is + adj.(描述人品性等) + of sb. to do sth.。故选B。
