49、 day long(by the boss)短语动词变被动语态时,勿要掉“尾巴”。The children were taken good care of(by her).Your pronunciation and spelling should be paid attention to.情态动词和be going to、be to、be sure to、used to、have to、had better等结构变被动语态,只需将它们后面的动词原形变为be+过去分词。,当句子的谓语为say、believe、expect、think、know、write、consider、report等时,被

50、动语态有两种形式:(A)谓语动词用被动语态,动词不定式作主补。(B)用it作形式主语,真正的主语在后面用主语在后面用主语从句来表示。如:People say he is a smart boy.It is said that he is a smart boy.He is said to be a smart boy.People know paper was made in China first.It is known that paper was made in China first.Paper was known to be made in China first.类似句型有:It
