provED是什么意思

1 动词过去式 证明2 过去分词 被验证的

prove 证明的意思

We have been accused of exaggerating before, but unfortunately all our reports proved to be true.我们曾被指责夸大其词,但遗憾的是,我们所有的报告都证明是真实的.In the past this process of transition has often proven difficult.在过去,这种转变过程常证明是艰难的.prove是个系动词意思是“证明是……”,后面可以加to be也可以不加的.没有被动式的.What he had said proved to be true.他所说的证明是对的.

整个句子为主、系、表结构:an opinion /is /what someone believes is true but has not been proved.这个句子比较复杂的是表语,是一个表语从句(也属于名词性从句).因为从句的宾语语中缺少成分而是用"what"引导.如果将what放回从句中,从句正常的语序是:someone believes/ "what" is true but has not been proved. 从句谓语是believes,后面是一个宾语从句,含有两个并列句,但主语都是what,因此but后面省略了主语.(what)has not been proved是一个被动句.不知我解释的明白否?

proved developed producing reserves探明的开发动用储量双语例句1I'll write the release order. proved developed producing reserves我给你开出院证明.探明的开发动用储量2Fuyang reservoir has low porosity and ultra low permeability, with low

是approved 吧是批准、审批的意思我们在制表的时候不经常有 批准 吗?就是那个

directed adj. 有指导的; 有管理的; 定向的; 被控制的 【数】标出(数, 角, 线段的)正负的 a directed study program 有指导的学习计划 oppositely directed 反向的 directed number 【数】(有加减号的)有向数

此句中prove相当于一个联系动词,等于prove to be,证明是,原来是,结果是(这样理解,但不要这样机械地翻译).此句的结构是主语+系动词+形容词做表语.退出支配地位的确十分痛苦.

意思:因为他的回答经证明是错误的.这是一个宾语从句,其实就是the answer proved wrong,是一个一般过去式,所以不能用proving和was proved.

adj.可靠地; 经过考验的v.试图,努力( try的过去式和过去分词); 考验; 磨炼; 审讯网 络试;想尽;尝试;努力
