＿＿（Be）honest is the first thing people should learn.

being

To be

答案:
To be.

To be 或者Being .

Being

to be

Being

Being

To be honest～是个固定词组

Be动词作主语要加ing

to be

to be honest 说实话

To be

应该是 To be

下楼全错，，是being 动词短语做主语应加ing

Being，动名词做主语，假如碰上其他填写开头的单词的话，应该看看句子里有没有am is are may(同一类的) do(一类的，必须是第一动词，就是谓语动词)等谓语。

to be 动词不定式也可以作主语

To be .
填To be
