*It is clear\important\likely\possible that 。*It is said\reported\estimated\has been proved that 。

What we lack is experience.3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序 。How the plan is to be carried out should be discussed again.I did know why I felt like crying.2.宾语从句1）宾语从句可位于及物动词、介词和某些形容词后 。
连词that常可省略 。介词后一般接疑问词引导的宾语从句 。

He has made it clear that he would not change his mind.3）在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式 。He didn't think that the money was well spent.3.表语从句表语从句出现在结构为“主语+系动词+表语从句”的句子中 。
