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。
