Question

英语句子 这两个句子哪个对？

We found the boy honest.
We found the boy is honest.

Answer 1

这两句话都对，但表达方式不同:
We found the boy honest.
用的是sb. find sth. +adj.句型，即某人发现某物……
We found the boy was honest.
用的是宾语从句，其中the boy was honest是宾语从句，主句是we found, found后面省略了从句引导词that。完整的应该是:We found that the boy was honest.

延伸:宾语从句知识点
一、宾语从句：置于动词、介词等词性后面，在句子中起宾语作用的从句叫做宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。宾语从句过"三关"：时态，语序，连词。宾语从句的语序必须是陈述语序，谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句，有些形容词(afraid，sure，glad等)之后也可以带宾语从句。
二、宾语从句中引导词的用法
在复合句中作主句的宾语，引导词有：
连词：that (that 常可省略),whether, if
代词：who, whose, what ,which
副词：when ,where, how, why 等。
(一)that引导的宾语从句(在非正式场合that可以省略)
可跟that从句作宾语的动词有：
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, r*equest, require, propose, declare, report等。
例句：The boy believes that he will travel through space to other planets.
注意事项：当主句谓语动词是 think, believe, suppose, expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。
例句：I don’t think it is right for him to treat you like that.
在以下情况中that不能省略
1、当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。
例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.
2、当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。
例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
3、当that从句是双宾语中的直接宾语时，that不可省。
例句：I can’t tell him that his mother died.
注意事项：许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。
例句：I find it necessary that we should do the homework on time.
(二)由whether,if 引导的宾语从句
由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。
例句：I wonder whether(if) they will come to our party.

(三)连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。用于这种结构的动词常常是：see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
英语中的连接代词有：who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。

Answer 2

第一句是简单句，honest作宾语the boy的补足语！
第二句是宾语从句，省掉了连接词that.
所以说两个句子都对。

Answer 3

两个句子都对。只不过第一句是简单句，第二句是从句。
