英語學習中如何掌握系動詞
系動詞又叫聯繫動詞，是聯繫主語和表語的成分，有時候在句子中的意思不翻譯，有的系動詞也有實際的意義。下面是小編給大家分享的英語系動詞用法，大家可以作爲學習的參考。
1、感官動詞
Feel, smell, sound, taste, touch
This flower smells very nice.
2、狀態系動詞,表主語狀態,只有be
He is a teacher.
3、持續性動詞,表示主語繼續或保持一種狀況或態度
Keep, rest, remain, stay, lie
He always keeps silent at class.
4、變化系動詞, 表示主語變成什麼樣
Become, grow, turn, fall, get, go, come, run
He became fat in winter holiday.
其實很多系動詞可以當系動詞,也可以當實義動詞,但用法有所不同。如:Look
Look at my hand 實義動詞,看
She looks amazing.系動詞
初中英語Be動詞定義及用法：
1、系動詞+表語”的結構
當be 動詞做系動詞使用時，主要構成“系動詞+表語”的結構，在句子中做謂語。表語可以是名詞、形容詞、副詞、介詞短語等。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 動詞的一般疑問句，方法是把be 移到主語前面，也可說成是移到句首。
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 動詞用在特殊疑問句
在特殊疑問句裏，be 動詞仍然移到主語前面，但特殊疑問句是以特殊疑問詞開頭的，所以be 動詞只能說是移到主語前面，或者說是在特殊疑問詞的後面。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 動詞的否定句
be 動詞做謂語時，它的否定形式是在be 後加not，並且可以縮寫。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 動詞的祈使句
be 動詞的祈使句有肯定和否定兩種形式。肯定形式是以be 動詞開頭，而否定形式或強調句形，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.
