系動詞分為
完全聯繫動詞表狀態，只有一個be（以及它的變形）
不完全聯繫動詞，如：
表感官的系動詞：look,sound,taste,smell,feel（這些詞用形容詞作表語）
表似乎的系動詞：seem,appear
表變化的系動詞：become,get,turn,grow,make,come,go,fall,run
表依舊的系動詞：remain,keep,stay,continue,stand,rest,lie,hold
可帶名詞作表語的系動詞：become,make,look,sound,fall,prove,remain,turn（該詞後接的單數名詞前多不用冠詞。如：He turned teacher.）
英語系動詞用法口訣
1.我用am，你用are，is連著他，她，它;
2.要想掌握Be（am,is and are）的用法，先分清第一人稱、第二人稱和第三人稱：
其餘都是第三人稱：單數she（她） he （他） it （它） 複數they（他們）
3.there be+賓語+過去分詞：
There is nothing written on it. 上面沒寫東西。There were ten people killed in the accident. 事故中有10人喪生。有時過去分詞也可表示一種狀態(可轉換成被動結構)：There were some old men seated (=who were seated) in the back. 有些老人坐在後面。There is a red car parked (=which is parked) outside the house. 房子外邊停著一輛紅色汽車。
4.there be+名詞+現在分詞：
There is someone waiting for him. 有人在等他。There was a man standing in front of me. 我前面站著一個男人。There were some children swimming in the river. 有些小孩在河裡遊泳。There were a group of young people working in the fields. 有一群青年在地裡勞動。There’s a piano standing against the wall. 靠牆有一架鋼琴。There’re a lot of difficulties facing us. 我們面前有很多困難。There is a door leading to the garden. 有一座門通往花園。有個別現在分詞用於該結構時可以表示將來(正如它們可用進行時表示將來一樣)：There are ten people coming to dinner. 有10個人來吃晚飯。
5.there be+賓語+不定式：
There was nobody to look after the child. 沒有人照顧這孩子。There was a large crowd to send him off. 有一大群人要來給他送行。There was so much to lose that we couldn’t take any risks. 可能會有很大的損失，因此我們不能冒險。當其中的賓語與其後的不定式為被動關係時，可用主動表被動，也可用被動式：There is much work to do [to be done]. 有許多工作要做。There is nothing to be afraid of. 沒什麼可怕的。What was there to be afraid of. 有什麼可怕的?
