believe
1.I believe him是“我信他的说话不错”，I believe in him是“我信他做人可靠”，就是“我信任他”，或者是“我相信他将来有所成就”。
2.下面三句意思相同：
- I believe (that) he is honest.
- I believe him to be honest.
- I believe him honest.
第二句比较不普通，在口语里更不普通。假使那动词不是be，通常不用不定式而用从句，如通常说As early as 1960 I believed (that) he belonged to a certain clan，不说As early as 1960 I believed him to belong to a certain clan。
但在believe用作被动语态的时候，后面接不定式很普通，例如He is believed to be honest和He was believed to belong to a certain clan。
3.I do not believe (that) he can do it和I believe (that) he cannot do it意思相同，但第二句不很自然。
4.I believe I told you, but I am not sure里的believe作suppose解。Mr Brown, I believe? 是“我想你就是Brown先生，是不是？”
5.make believe是习语，作“假做”解，如He made believe to be ill和He made believe (that) he was ill。这里的believe是不定式，因为前面是make，所以省去to。make没有宾语，是不带特定宾语的用法。
