在一般现在时中,当主语是第三人称单数时,谓语动词也要用第三人称单数,即在原动词后常加-s或-es。让我们告诉你关于英语动词后面加s的用法.的事情,让我们看看吧!
英语动词后面加s的用法:

二、单个人名、地名或称呼作主语;是第三人称单数。如:

动词keep主要用法归纳:
1. 表示“保持”,用作连系动词,其后可接形容词或介词短语等作表语。如:
She knew she must keep calm. 她知道她必须保持冷静。
We’ll keep in touch with you. 我们将和你保持联系。
2. 表示“保持”,用作实义动词,其后可接动名词作宾语,但不能接不定式。如:
Prices keep rising. 物价不断上涨。
Please don’t keep running up and down the stairs. 请别老在楼梯上跑上跑下。
根据语义的需要,其后可接带形容词、副词、介词短语、现在分词、过去分词等的复合结构,但不能接带不定式的复合结构。如:
You must keep it a secret. 这事你得保密。
Sorry to have kept you up so late. 对不起让你这么晚都没睡。
A cold kept him in bed for three days. 一次感冒让他卧床3天。
She kept us waiting for a long time. 她让我们等了很久。

3. 比较keep doing sth与keep on doing sth:两者均可表示反复发生的动作(即动作之间略有间隔)。如:
They kept (on) talking about it. 他们一直在谈论此事。
但是,如果表示持续的状态或连续不断的动作(动作之间没有间隔)时,通常只用keep doing sth。如:
He kept standing during the meeting. 开会时他一直站着。
另外,表示将一直在做的事继续做下去,通常只用 keep on doing。如:
He kept on working after dark. 天黑了我们还继续干。
Don’t give up; keep on trying. 别灰心,继续努力。
4. 比较keep doing sth与keep from doing sth:前者指不停地做某事,后者指克制自己不做某事。如:
I could hardly keep from laughing. 我简直忍不住大笑起来。
I hope you will keep from doing anything rash. 我希望你不要鲁莽行事。
5. 比较keep sb doing sth与keep sb from doing sth:前者指使某人不停地做某事,后者指使某人不做某事。如:
The snow kept us from going out. 下雪使我们没法出去。
He hung around for hours and, which was worse, kept me from doing my work. 他闲待了好几个钟头,更糟糕的是,这使我也没法工作。
动词happen的语法特点及句型搭配:
1. 表示“发生”,是不及物动词,因此既不能带宾语,也不能用于被动语态。如:
事故是怎样发生的?
误:How was the accident happened?
正:How did the accident happen?
2. 表示某事发生某人身上,其后接介词 to。如:
Nobody will ever know what happened to her. 谁都不会知道她出了什么事。
She hoped nothing bad would happen to him. 她希望不会有坏事发生在他头上。
3. 表示“碰巧”,也是不及物动词,比较以下同义句型:
我昨天偶然在公园里看到她。
I happened to see her in the park yesterday.
=It (so) happened that I saw her in the park yesterday.
4. 后接介词 on / upon,表示“巧遇”“偶然发现”。如:
I happened upon her in the street the other day. 几天前我在街上碰巧遇见了她。
He happened on the book in the bookstore. 他在书店偶然发现了这本书。
5. 用于as it happens,意为“偶然”“碰巧”。如:
As it happens, I have left the book at home. 我碰巧把书忘在家里了。
We met her only yesterday, as it happens. 我们只是在昨天才与她偶然相遇。
动词follow的用法与搭配:
1. 表示“跟随”,可用作及物或不及物动词。如:
Follow close behind. 紧跟在后面。
Summer follows spring. 春去夏来。
The dog follows me wherever I go. 我不论到哪里,这狗都跟着。
表示某人或某物跟在另一人或另一物后面,一般不与介词behind 或after 连用,以免构成用词重复(尽管偶尔可见到这类用法,但在现代英语中很少见,初学者最好不用)。但有时可后接用作副词的behind。如:
You go ahead. We’ll follow behind. 你们先走,我们随后就来。
2. 有时与there搭配使用, 构成类似there be的结构。如:
There followed a long silence. 然后是一阵冗长的沉默。
There will follow an interval of five minutes. 随后将有5分钟休息。
3. 不要按照汉语习惯,将汉语表达中的“跟着某人做某事”直译为 follow sb to do sth, 而应根据情况选用适当的句型。如:
我跟他去了车站。
误:I followed him to go to the station.
正:I followed him to the station.
我跟着他读生词。
误:I followed him to read the new words.
正:I read the new words after him.
4. follow的用法很多,除表示“跟着”外,还可表示“听从”“遵循”“沿着”“仿效”“听懂”“明白”等义。如:
Do you follow me? 你能听懂我的话吗?
Follow the traffic rules. 遵循交通规则。
We should follow his advice. 我们应该听他的劝告。
He followed his sister’s example and went to college. 他效仿他的姐姐也进了大学。
Follow this road until you get to the corner, then turn left. 沿着这条路走到拐角处,然后向左拐。
