忠告用英语怎么说

不可以加advice在作“忠告”解时是不可数名词，只有在作“消息”等解时是可数名词。

advice与suggest的异同点一、advise与suggest都有“建议”的意思1)都可接名词作宾语She suggested /advised an early start. 她建议早一点出发.We suggested /advised a visit to the museum the next day. 我们建议明天去参观博物馆.2)都可接动名词作宾语I suggested /advised putting off the sports meet. 我建议将运动会延期.They suggested /advised waiting until the proper time. 他们建议(我们)等到恰当的时机才行动.3)都可接that 宾语从句,that从句用should+动词原形,should可以省略.She suggested /advised that the class meeting (should) not be held on Saturday. 她建议班会不要在星期六举行.We suggested /advised that he (should) go and make an apology to his teacher. 我们建议他去向老师道歉.4)advise 可接动词不定式复合宾语I advised him togive up the foolish idea. = I suggested his / him giving up the foolish idea. 我建议他放弃那愚蠢的念头.(suggest在口语里可接动名词的复合宾语).接不定式不用suggest和advise二、 有"提出"的意思.如:He suggested adifferent plan to his boss. 他向老板提出了一个不同的计划.Xiao Wangsuggested a way to solve the problem. 小王提出了一个解决这个问题的办法.三、 有"暗示、表明"的意思.其主语往往是事物,而不是人.1)接名词或动名词作宾语.The simple housesuggested a modest income. 这座简朴的房子表明(房主的)收入并不高.Her pale face suggestedbad health. 她脸色苍白,看来身体不好.The thought ofsummer suggests swimming. 一想到夏天就使人们联想到游泳.2)接宾语从句,从句用陈述语气.如:The decisionsuggested that he might bring his family. 这个决定表明他可以把家属带来.The expression onhis face suggested that he was very angry. 他脸上的表情表明他很生气.四、 在主语从句Itis suggested that... 及名词suggestion 后面表示具体建议的表语从句、同位语从句都应用should+动词原形,should可以省略.如:It was suggestedthat we (should) give a performance at the party. 人们建议我们在晚会上表演节目.His suggestion wasthat the debts (should) be paid off first. 他的建议是先把债务还清.The doctors made asuggestion that the new hospital (should) not be set up on the hill. 医生们建议不要把新医院建在山上advise与suggest都可作“建议”讲，二者用法有同有异。1）相同点都可表示建议做某事， advise与suggest后面都可接名词/动名词/ that从句（should加动词原形，should可以省略）。例如：他建议（我们）再等一会儿。He advised/suggested waiting a bit longer.He advised/suggested (our) waiting a bit longer.He advised/suggested that we (should) wait a bit longer.上面的第三句可转化为：It was suggestedthat we (should) wait a bit longer.What he suggestedwas that we (should) wait a bit longer.His suggestion wasthat we (should) wait a bit longer.(2)不同点①advise后可以直接跟人称代词作宾语，如：advise sb. to do sth.; advise sb. against(doing) sth.; advise sb. on/ about sth.; 而suggest后一般用suggest to sb that …形式。如：他建议我们改天再来。[正]Headvised us to come another day.[误]Hesuggested us to come another day.[误]Hesuggested us that we come another day.②suggest还有“暗示、表明、指出（一个事实）”的意思。此时从句中用陈述语气，不用虚拟语气。如：Her expressionsuggested pleasure. 她面露喜色。His silence couldonly suggest disapproval. 他的沉默只能暗示反对。

加s 未尝不可，只是不符合现在的使用习惯了.类似的是suggestions

suggest和advice在词性、用法与释义上有所不同。

一、词性不同

1、suggest是动词词性

2、advice是名词词性

二、接that从句时的用法不同

1、suggest接that从句作宾语时,从句中的谓语动词要用虚拟式; 作“表明,暗示”“使想起”等解时,从句中的谓语动词可用陈述式。

2、advice后接that从句时，句中要用should或虚拟现在式。

三、释义不同

二者都有“建议”的意思，具体区别为：

1、suggest基本意思是“建议”“提议”,还可表示“暗示,表明”“使想起”等。

2、advice还有劝告、忠告的意思。有业务专长或经验(可真可假)的人对某一行动提出的带指点或指教性的意见或劝告,如教师对学生的指教或医生对病人的劝告等,也指商业上关于交易等资料的通知(单)
