是的
现在完成时（Present perfect）过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在的动作或状态.
基本结构：主语+have/has+过去分词(done)
①肯定句：主语+have/has+过去分词+其他.
②否定句：主语+have/has+not+过去分词+其他.
③一般疑问句：Have/Has+主语+过去分词+其他.
④特殊疑问句：特殊疑问词或词组+一般疑问句 have/has+主语+过去分词+其他
定义：
（1）强调动作是过去发生的
（2）强调对现在的影响或结果
（3）在过去不确定的时间里发生的动作,但是结果对现在有影响.
但过去分词一定要选择准确.
现在完成时 have/has + done
现在完成时的被动语态 have/has＋been done
现在完成时的标志性时间状语already ,ever ,never ,yet ,just ,before,still ,lately ,since ,for a long time ,up to now,until,so far,in the last few years/weeks/mouths ,till now,recently
综合上述来看,We haven't come to a conclusion yet.是个标准的现在完成时的句子.
希望可以帮到你哦,如果语法不好的话建议买本语法书自己慢慢啃透吖,因为毕竟语法不是一时半会儿就能学来的,英语这门课的知识很零碎,是要每一天积攒起来的.……
