1)修饰形容词或副词时,通常放在前面。 2)当句子的谓语动词是行为动词时,频度副词一般放在谓语动词之前。句中有be或助动词、情态动词时,放在其后。 【例如】 I often go to the cinema on weekend with my husband. I can hardly understand him for what he said was really confusing.have never been abroad until now. 3)程度副词修饰形容词或副词,通常放在被修饰的形容词之前。但是enough总是放在所修饰的形容词或副词之后。 【例如】 The boy didn’t work hard enough. He is quite diligent. But his achievement is not good enough. 4)only的位置比较灵活,修饰哪个词,就放在哪个词的前面,以示强调。 【例如】 I only saw John yesterday. I didn’t see his wife. I have bought two kilos of potatoes only. Only in the afternoon, can you borrow books from the university library.
