题型：不详难度：来源：
_____ very important to have good eating habits.| A．That’s | B．It’s | C．He’s | D．This is |
|
答案
| B |
解析
试题分析：句意：一个好的饮食习惯是非常重要的。it作为形式主语，后面的不定式to have good eating habits作为真正的主语，故选B.
点评：英语句子中为了避免“头重脚轻”常用It作为形式主语，初中常考的还有It’s+形容词+of+sb to do sth与It’s+形容词+for+sb to do sth的区别在于，如果形容词人性的，如友好的，大方的等就用of;如果形容词是物性的，如事情的难易程度、重要性等就用for,本题中important重要的，指物性的形容词。 |
