题目内容
6.It's dangerous a close look at the tiger in the zoo.( )| A. | for us taking | B. | of us to take | C. | of us taking | D. | for us to take |
分析 在动物园里近距离地看老虎是危险的.
解答 答案:D 根据关键词It's dangerous并结合选项可知此句考查固定句式:it可指代下文内容做形式主语,其真正的主语是由后面的不定式充当的.其主要有两种形式:1、It's+形容词+of+sb+to do sth.这个句型,形容词一般为sb的所具有的一种品质性格.2、It's+形容词+for+sb+to do sth.这个句型,形容词不是sb所具备的品质性格;如果形容词是描述人的性格特征方面的形容词则用of,否则用for.本题中的形容词为dangerous,不是描述人的性格特征的,所以应用for.故选D.
点评 做好本题的关键是知道固定句型It's+adj of sb+to do sth和It's+adj for sb+to do sth的区别及用法,联系具体的句子做出正确的选择.
