Question

16．想成功，不要轻易放弃很重要．
In order to achieve success，it is important not to give up easily．

Answer 1

分析 it is important not to give up．

解答 答案：it is important not to give up．
这里是表示做某事是怎么样的，用it作为形式主语，动词不定式做真正主语，构成句型it is+adj+to do sth，重要的important，放弃give up．否定式将not放在动词不定式前，故答案是it is important not to give up．

点评 it作为形式主语，动词不定式做真正主语的句型还有It+be+名词词组+动词不定式，如：It is not a good habit to stay up too late
