用find sb英语造句,分别用adj,p.p,doing,还有phrase这四种词性各造一个句子.

find sb doing sth或是find sb have done sth或是find sth done,have可以省略.

interested
‘发现某人对数学感兴趣’
这里的interested的意思是‘感兴趣’,一个动词.
interested in sth.固定搭配

差不多是这样的..你可以看看详细的用法
一、find意为"发现、发觉"
作此意解时,其后接宾语+宾补(分词、形容词、副词、名词、介词短语或to be).作宾补的动词用现在分词还是过去分词取决于动词同宾语之间的关系.
A group of children were found playing on the playground.有人发现一群孩子正在操场上玩耍.
We have found him (to be) a dishonest person.我们发现他是一个不诚实的孩子.
I find it necessary to get a map while traveling.我感到旅行的时候有必要搞到一张地图.
二、find意为"找到、寻找"
应当注意,find作"找到,寻找"解时,侧重寻找的结果;而look for则侧重寻找的过程.
I lost my cellphone this morning.I've been looking for it ever since,but I haven't found it.今天上午我把手机丢了.从那时起我就一直在找,可是到现在还没找到.
三、find后接从句
find后可接that-clause,表示"发现一个事实、道理".
He found that some of the natives knew his language.他发现有几个本地人懂他的语言.
四.find构成的常用短语
find oneself(发现自己真实的能力、性格等);find fault with(抱怨;挑剔);find one's way to(设法到达)等.
The manager is always finding fault with my work.经理总是对我的工作吹毛求疵.
I hope you can find your way home.我希望你能找到回家的路.

find sb.+形容词 sb.是宾语 形容词是宾语补足语 用来补充说明宾语的
和find用法一样的还有think

可以啊.形容词在句子中作宾补.
例：He found it important to study hard.
