謂語
謂語(predicate verb)是對主語動作或狀態(tài)的陳述或說明,指出“做什么”、“是什么”或“怎么樣”。謂語動詞的位置一般在主語之后。
謂語由動詞充當,說明主語所作的動作或具有的特征和狀態(tài)。依據其在句中繁簡程度可把謂語分為簡單謂語和復合謂語兩類。不論何種時態(tài)、語態(tài)、語氣,凡由一個動詞(或動詞詞組)構成的謂語都是簡單謂語。
簡單謂語:
由動詞、動詞短語或者動詞的時態(tài)構成。如:
I like walking. (一般現在時主動語態(tài))
I made your birthday cake last night. (一般過去時主動語態(tài))
It is used by travellers and business people all over the world. (一般現在時被動語態(tài))
復合謂語:
1.由情態(tài)動詞或助動詞+不帶to的動詞不定式構成。如:
You may keep the book for two weeks.
He has caught a bad cold.
My sister is crying over there.
I have been waiting for you all the time.
I would stay at home all day.
2.由系動詞加表語構成。系動詞不能單獨作謂語,要和表語一起作謂語。
