1. 最基本的系动词就是be。
e.g. My sister is a good swimmer.
Jane is very quiet.
Who is she
He isn’t at home now.
To know everything is to know nothing.
系动词be后面可以跟各种各样的表语，如名词(短语)、形容词、代词、介词短语、不定式等。
e.g. This bed feels hard.
这张床摸起来硬邦邦的。
The biscuits taste sweet.
饼干吃起来甜甜的。
You look tired.
你看上去累了。
The milk smells sour.
牛奶闻起来有股馊味儿。
The idea sounds good.
这主意听起来不错。
2. 很多感官动词，如feel，taste，look等，也可以当系动词使用。
感官司动词后多跟形容词作表语。
3. go，get，become等动词也可以作为系动词。
e.g. The meat goes bad. 肉变质了。
It was getting very dark.
天越来越黑了。
Leaves become yellow in autumn.
叶子在秋天会变黄。
He turned scientist. 他变成科学家了。
变化系动词后多跟形容词或名词作表语。
go，get，become用于描述人或事物的状态发生某种变化。
e.g. Her room remains clean and tidy.
她的房间一直保持干净整洁的状态。
He remains calm in trouble.
在遇到麻烦时，他仍保持冷静。
Please keep quiet in the library.
在图书馆请保持安静。
Ann stayed in bed the whole morning.
Ann整个早上都呆在床上。
表示保持某种状态的系动词后，可跟形容词、副词、名词、介词短语等作表语。
4.在表示人或事物的状态保持一致、没有发生变化时，可使用remain，keep，stay。
5. 系动词seem（似乎、好像）后可跟形容词、名词等作表语。
e.g. Jane seems sick today.
Jane今天好像生病了。
That seems a good idea.
那似乎是个好主意。
He appeared calm.
他显得很冷静。
e.g. The dishes do not smell very nice.
这些菜肴闻起来不是很好。
Does he look worried
他看起来焦虑吗？
The cake does not taste very good.
这个蛋糕不是很好吃。
1.除 be 以外的系动词，其他否定形式和疑问形式的构成要借助助动词do、does。
有些动词既可作系动词，又可作实义动词，这时要根据其意思以及后面所接词的词性和词义作出判断。
He is looking at the picture.
(实义动词，本句用现在进行时，表示“看”。)
It looks beautiful.
(系动词，后接形容词作表语，表示“看起来”。)
2.部分表示变化的系动词可用于进行时态。
I feel someone touch my arm.
(实义动词，后接名词作宾语。)
I feel comfortable in my room.
(系动词，后接形容词作表语，表示“感觉”。)

(系动词，后接形容词作表语。)

(实义动词，后接名词作宾语，表示“种植”。)
