Answer 1

分析 It's important for us to try to guess its meaning instead of looking it up in a dictionary．

解答 答案：It's important for us to try to guess its meaning instead of looking it up in a dictionary．
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it's+adj+for sb+to do sth，it是形式主语，动词不定式是真正主语，try to do sth设法做某事，guess猜，故guess its meaning猜测其词义，而不是instead of，后加动名词短语，look it up in a dictionary查字典，故答案是It's important for us to try to guess its meaning instead of looking it up in a dictionary

点评 It's+adj．+for sb．to do sth．结构是一个陈述句，表示说话人对客观事件的决断，比较正式，希望大家学习时注意．  若形容词是描述不定式行为者的性格、品质的，如kind，good，nice，right，wrong，clever，careless，polite，foolish等，用of sb．
