单数主语、单个动词不定式、动名词短语以及句子作主语，谓语动词要用单数形式。复数主语，用and或both…and连接的动词不定式短语、动名词短语以及主语从句作主语，谓语动词则用复数形式。下面小编告诉你英语动词单复数用法，大家一起来看看吧!英语动词单复数用法：1. 动词的数是指动词的变化反映主语的单复数变化。I am the best friend of Tom.我是汤姆最好的朋友。I am a student.我是学生。主语是单数,动词用BE的第一人称单数形式am。Yes. And we both are students of this class.是的。而且我们都是这个班的学生。We are students.我们是学生。主语是复数,动词用BE现在式的复数形式are。He speaks English.他讲英语。主语是第三人称单数,动词用speak的第三人称单数形式speaks。2. 第三人称单数动词的简单现在式由原形动词加s构成。规则1:通常动词在原形后面加直接s。如:arrive→arrivesforget→forgetsfind→findshate→hatesHe likes chatting with me.他喜欢和我聊天。规则2:以字母s,ss,x,z,sh,ch等结尾的动词在原形后面加es。如:pass→passesfinish→finishesfix→fixescatch→catchesbuzz→buzzes。He passes them back to me.他把它们传回给我。规则3:以字母o结尾的动词在原形后面加es。如:go→goesdo→doesecho→echoes。My boys, don"t expect everything always goes well!孩子们,别以为事情总能进展顺利!规则4:以母音字母+y结尾的动词直接加s。如:play→playsenjoy→enjoysbuy→buysNow he still enjoys chatting with me.现在他仍喜欢和我聊天。规则5:以子音字母+y结尾的动词将y改为i,再加es。如:try→triesfly→fliessatisfy→satisfiesstudy→studies。动词accept的用法：1. 表示“接受”，可及物或不及物。如：She offered him a lift and he accepted (it). 她请他坐她的车，他就领情了。He asked her to marry him and she accepted (him). 他向她求婚，她同意了。比较：accept 与 receive用法不同，前者通常指被动地“收到”或“接到”，而后者则指主动地“接受”。如：She received his present, but she didn’t accept it. 她收到了他的礼物，但是没有接受。注意，有时用词要视语言习惯而定，而不能简单地认为 receive=收到，accept=接受。如“接受礼物”说成英语是 accept a gift, 而“接受教育”却是 receive an education。2. 其后可接名词或代词作宾语，但一般不接不定式。要表示汉语的“接受做某事”，可用agree to do sth。如：他的想法是那样好，我们都同意采用。误：His idea was such a good one that we all accepted to use it.正：His idea was such a good one that we all agreed to use it.动词suggest的用法：1. 用作动词，表示“建议”“提议”，其后接动词时要用动名词，而不用不定式。如：I suggest going in my car. 我建议坐我的车去。He suggested taking the children to the zoo. 他提议带孩子去动物园。若是后接从句，多用虚拟语气(should+v.)。如：He suggested that we (should) come another day. 他建议们改日再来。但是注意，不要按汉语习惯在其后接不定式的复合结构。如：他建议我们买台辆新车。正：He suggested our buying a new car.正：He suggested that we (should) buy a new car.误：He suggested us to buy a new car.在现代英语中 suggest表示“建议”时，其后所接的从句也可不用“should+v.”的虚拟语气形式，但不算很普通，初学者宜慎用。如：I suggest that you don’t go. 我建议你不要去。2. 表示“暗示”“表明”“指出”“提出(看法)”等义，若后接that-从句，通常用陈述语气。如：His smile suggested that he was satisfied. 他的微笑表明他是满意的。I’m not suggesting that the accident was your fault. 我并不是说这个事故是你的错。Others suggest that they two will be equals. 其他人认为他们俩将是势均力敌。3. 不能接双宾语，若含义上需要接双宾语，可用介词 to。如：What did you suggest to the manager? 你向经理提了什么建议?He suggested to us that we should go by train. 他向我们提议坐火车去。比较以下用介词 for, as 的例子：Whom would suggest for the job? 你建议由谁来做这工作?I suggest Paris as a good place for honeymoon. 我建议去巴黎，那是个度蜜月的好地方。动词allow的用法：1. allow (doing) sth 允许(做)某事。如：The facts allow no other explanation. 事实不允许有其他的解释。We don’t allow eating in the classrooms. (我们)不允许在教室吃饭。注：有时用于被动语态。如：Dogs are not allowed. 狗不得入内。Smoking is not allowed here. 此处不准吸烟。2. allow sb to do sth 允许某人做某事。如：My parents don’t allow me to go out at night. 我父母不允许我晚上出去。Her boss doesn’t allow her to use the telephone. 她的老板不允许她使用电话。注：有时用于被动语态。如：Passengers are not allowed to smoke. 乘客不准吸烟。3. allow sb sth 给予某人某物(尤指钱或时间);让某人有(拥用或带有)某物。如：He allows his son too much money. 他给他儿子的钱太多。We’ll allow you time to answer. 我们将给回答的时间。I will allow you 10% off the price if you pay now. 如果你现在付款，我可以给你打九折。We allow passengers one item of hand luggage each. 我们允许每个乘客带一件手提行李。注：有时用于被动语态。如：I’m not allowed visitors. 我不准有访客。4. allow for 考虑到，把……考虑进来，体谅。如：We should allow for every possible delay. 我们考虑到任何可能的延误。We must allow for his youth. 我们必须体谅他的年轻。
