Question

9．我們互相支持、互相幫助很重要．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．表達(dá)的是客觀事實用一般現(xiàn)在時，表示對某人來說做某事是怎樣的用句型it's+adj+for sb to do sth，it是形式主語，動詞不定式是真正主語，important重要的，支持support，help幫助，用and連接，彼此each other，故答案是It's important for us to support and help each other．

點評 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點，表示客觀形式的形容詞，如easy，hard，difficult，interesting，impossible等：
　　 It's very hard for him to study two languages．對他來說學(xué)兩門外語是很難的．
2）of sb的句型一般用表示人物的性格，品德，表示主觀感情或態(tài)度的形容詞，如good，kind，nice，clever，foolish，right．
　　 It's very nice of you to help me．你來幫助我，你真是太好了．
