句子中如果没有实意动词之类的动词，就直接在主语后面加Be动词。下面小编告诉你小学五年级英语be动词用法，大家一起来看看吧!
小学五年级英语be动词用法：
1、系动词+表语”的结构
当be 动词做系动词使用时，主要构成“系动词+表语”的结构，在句子中做谓语。表语可以是名词、形容词、副词、介词短语等。例如：
The man is a science teacher.
Mary's new dresses are colourful.
Mother is in the kitchen now.
I have been there before.
They shall be here at 10:00 tommorow.
That can't be true.
You are not being very polite.
Your brother is being very annoying this evening
2、be 动词的一般疑问句，方法是把be 移到主语前面，也可说成是移到句首。
Is the man a science teacher? Yes, he is. / No, he isn't.
Are Mary's new dresses colourful? Yes, they are. / No, they aren't.
Was mother in the kitchen then? Yes, she was. / No, she wasn't.
Were you at home the day before yesterday? Yes, I was. / No, I wasn't.
Was she late this morning? Yes, she was. / No, she wasn't.
3、be 动词用在特殊疑问句
在特殊疑问句里，be 动词仍然移到主语前面，但特殊疑问句是以特殊疑问词开头的，所以be 动词只能说是移到主语前面，或者说是在特殊疑问词的后面。例如：
Whose bike is broken? Xiao Ming's bike is.
Who was singing in the room? Mr. Zhang was.
Where are you from? I am from Wuhu.
What class were you in? We were in Class 2.
How old is Tom? He is ten.
4、be 动词的否定句
be 动词做谓语时，它的否定形式是在be 后加not，并且可以缩写。例如：
It is not sunny today.
Tom and his friends are not in the park.
You were not nine years old when I went to the university.
He was not often late for his class when he was a student.
I wasn't here yesterday.
My parents weren't at home last Sunday.
5、be 动词的祈使句
be 动词的祈使句有肯定和否定两种形式。肯定形式是以be 动词开头，而否定形式或强调句形，要加don't 或do。例如：
Be careful!
Be a good boy!
Don't be silly!
Don't be a fool!
Do be obedient!
Do be careful.
动词congratulate的用法：
1. 其宾语通常是人，不是事;要表示因某事而祝贺某人，可用congratulate sb on [upon] sth。如：
我祝贺他取得成功。
正：I congratulate him on his success.
误：I congratulate his success.
2. 其后习惯上不接不定式的复合结构作宾语，即不说congratulate sb to do sth，可改为congratulate sb on doing sth。
He congratulated us on getting married. 他祝贺我们结婚大喜。
3. 有时接反身代词作宾语。如：
You can congratulate yourself on having done a good job. 你的工作干得出色，你应该感到自豪。
动词compare的用法：
1. 表示“把……与……比较”，通常用 compare...with...，但在现代英语中，也可用compare... to...，或者用 compare...and...。如：
If you compare his work with [and] hers, you’ll find hers is much better. 要是把他俩的工作比较一下，就会发现她的好得多。
Having compared the new dictionary with [to, and] the old one, he found the new one more helpful. 将新旧词典比较之后，他发现新词典更有用。
2. 表示“把……比作……”，通常用 compare...to...，一般不用 compare...with...。如：
Shakespeare compared the world to a stage. 莎士比亚把世界比作舞台。
The poet compares the woman he loves to a rose. 诗人把他所爱的女人比作玫瑰。
3. 在 compared to [with](与……相比)这一习语中，用 to 或 with 已没什么区别。如：
Compared with [to] him, I’m just a beginner. 和他相比，我只是一个初学者。
Compared to [with] many women, she was very fortunate. 和许多女人相比，她算是很幸运的了。
4. 用作不及物动词时，compare 后习惯上只接 with，多与情态动词 can 连用，表示“比得上”“能与……比美”，但一般用于否定句或疑问句中。如：
Nothing can compare with wool for warmth. 没有比羊毛更暖和的东西了。
Life in a town can’t compare with life in the country. 乡村的生活比城镇的生活好得多。
动词advance的用法：
(1) 表示朝着某个方面前进，通常后接介词 to, towards。如：
The troops advanced to the river. 部队行进到河边。
They advanced towards the castle. 他们向城堡推进。
He advanced towards me in aggressive style. 他向我步步进逼。
(2) 表示“朝……进发或挺进”，通常后接介词on, upon。如：
The army advanced on the capital. 部队向首都挺进。
Napoleon’s army advanced on Moscow. 拿破仑的军队向莫斯科推进。
(3) 表示进攻的对象，通常用介词 on, upon。如：
The soldiers advanced on the enemy. 士兵们向敌人进击。
They advanced upon the enemy. 他们向敌人进攻。
(3) 表示“把……提前”时，通常与from…to…短语搭配使用，与postpone互为反义词。如：
The date of the meeting was advanced from 10 to 3 June. 会议日期已由6月10日提前到6月3日。
(4) 表示“预支(钱)”“借(钱)”，通常接双宾语。如：
The bank advanced me $5,000. 银行借给我5,000美元。
He asked his employer to advance him a month’s salary. 他请求雇主先预支一个月的薪水。
