Question

9．我们互相支持、互相帮助很重要．It's important for us to support and help each other．．

Answer 1

分析 It's important for us to support and help each other．

解答 答案：It's important for us to support and help each other．表达的是客观事实用一般现在时，表示对某人来说做某事是怎样的用句型it's+adj+for sb to do sth，it是形式主语，动词不定式是真正主语，important重要的，支持support，help帮助，用and连接，彼此each other，故答案是It's important for us to support and help each other．

点评 It is adj+for/of sb to do sth的各自的用法 1）for sb．常用于表示事物的特征特点，表示客观形式的形容词，如easy，hard，difficult，interesting，impossible等：
　　 It's very hard for him to study two languages．对他来说学两门外语是很难的．
2）of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good，kind，nice，clever，foolish，right．
　　 It's very nice of you to help me．你来帮助我，你真是太好了．
